+Notes on the Free Translation Project
+*************************************
+
+ Free software is going international! The Free Translation Project
+is a way to get maintainers of free software, translators, and users all
+together, so that will gradually become able to speak many languages.
+A few packages already provide translations for their messages.
+
+ If you found this `ABOUT-NLS' file inside a distribution, you may
+assume that the distributed package does use GNU `gettext' internally,
+itself available at your nearest GNU archive site. But you do _not_
+need to install GNU `gettext' prior to configuring, installing or using
+this package with messages translated.
+
+ Installers will find here some useful hints. These notes also
+explain how users should proceed for getting the programs to use the
+available translations. They tell how people wanting to contribute and
+work at translations should contact the appropriate team.
+
+ When reporting bugs in the `intl/' directory or bugs which may be
+related to internationalization, you should tell about the version of
+`gettext' which is used. The information can be found in the
+`intl/VERSION' file, in internationalized packages.
+
+Quick configuration advice
+==========================
+
+ If you want to exploit the full power of internationalization, you
+should configure it using
+
+ ./configure --with-included-gettext
+
+to force usage of internationalizing routines provided within this
+package, despite the existence of internationalizing capabilities in the
+operating system where this package is being installed. So far, only
+the `gettext' implementation in the GNU C library version 2 provides as
+many features (such as locale alias, message inheritance, automatic
+charset conversion or plural form handling) as the implementation here.
+It is also not possible to offer this additional functionality on top
+of a `catgets' implementation. Future versions of GNU `gettext' will
+very likely convey even more functionality. So it might be a good idea
+to change to GNU `gettext' as soon as possible.
+
+ So you need _not_ provide this option if you are using GNU libc 2 or
+you have installed a recent copy of the GNU gettext package with the
+included `libintl'.
+
+INSTALL Matters
+===============
+
+ Some packages are "localizable" when properly installed; the
+programs they contain can be made to speak your own native language.
+Most such packages use GNU `gettext'. Other packages have their own
+ways to internationalization, predating GNU `gettext'.
+
+ By default, this package will be installed to allow translation of
+messages. It will automatically detect whether the system already
+provides the GNU `gettext' functions. If not, the GNU `gettext' own
+library will be used. This library is wholly contained within this
+package, usually in the `intl/' subdirectory, so prior installation of
+the GNU `gettext' package is _not_ required. Installers may use
+special options at configuration time for changing the default
+behaviour. The commands:
+
+ ./configure --with-included-gettext
+ ./configure --disable-nls
+
+will respectively bypass any pre-existing `gettext' to use the
+internationalizing routines provided within this package, or else,
+_totally_ disable translation of messages.
+
+ When you already have GNU `gettext' installed on your system and run
+configure without an option for your new package, `configure' will
+probably detect the previously built and installed `libintl.a' file and
+will decide to use this. This might be not what is desirable. You
+should use the more recent version of the GNU `gettext' library. I.e.
+if the file `intl/VERSION' shows that the library which comes with this
+package is more recent, you should use
+
+ ./configure --with-included-gettext
+
+to prevent auto-detection.
+
+ The configuration process will not test for the `catgets' function
+and therefore it will not be used. The reason is that even an
+emulation of `gettext' on top of `catgets' could not provide all the
+extensions of the GNU `gettext' library.
+
+ Internationalized packages have usually many `po/LL.po' files, where
+LL gives an ISO 639 two-letter code identifying the language. Unless
+translations have been forbidden at `configure' time by using the
+`--disable-nls' switch, all available translations are installed
+together with the package. However, the environment variable `LINGUAS'
+may be set, prior to configuration, to limit the installed set.
+`LINGUAS' should then contain a space separated list of two-letter
+codes, stating which languages are allowed.
+
+Using This Package
+==================
+
+ As a user, if your language has been installed for this package, you
+only have to set the `LANG' environment variable to the appropriate
+`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code,
+and `CC' is an ISO 3166 two-letter country code. For example, let's
+suppose that you speak German and live in Germany. At the shell
+prompt, merely execute `setenv LANG de_DE' (in `csh'),
+`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
+This can be done from your `.login' or `.profile' file, once and for
+all.
+
+ You might think that the country code specification is redundant.
+But in fact, some languages have dialects in different countries. For
+example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The
+country code serves to distinguish the dialects.
+
+ The locale naming convention of `LL_CC', with `LL' denoting the
+language and `CC' denoting the country, is the one use on systems based
+on GNU libc. On other systems, some variations of this scheme are
+used, such as `LL' or `LL_CC.ENCODING'. You can get the list of
+locales supported by your system for your country by running the command
+`locale -a | grep '^LL''.
+
+ Not all programs have translations for all languages. By default, an
+English message is shown in place of a nonexistent translation. If you
+understand other languages, you can set up a priority list of languages.
+This is done through a different environment variable, called
+`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG'
+for the purpose of message handling, but you still need to have `LANG'
+set to the primary language; this is required by other parts of the
+system libraries. For example, some Swedish users who would rather
+read translations in German than English for when Swedish is not
+available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
+
+ In the `LANGUAGE' environment variable, but not in the `LANG'
+environment variable, `LL_CC' combinations can be abbreviated as `LL'
+to denote the language's main dialect. For example, `de' is equivalent
+to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
+(Portuguese as spoken in Portugal) in this context.
+
+Translating Teams
+=================
+
+ For the Free Translation Project to be a success, we need interested
+people who like their own language and write it well, and who are also
+able to synergize with other translators speaking the same language.
+Each translation team has its own mailing list. The up-to-date list of
+teams can be found at the Free Translation Project's homepage,
+`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
+area.
+
+ If you'd like to volunteer to _work_ at translating messages, you
+should become a member of the translating team for your own language.
+The subscribing address is _not_ the same as the list itself, it has
+`-request' appended. For example, speakers of Swedish can send a
+message to `sv-request@li.org', having this message body:
+
+ subscribe
+
+ Keep in mind that team members are expected to participate
+_actively_ in translations, or at solving translational difficulties,
+rather than merely lurking around. If your team does not exist yet and
+you want to start one, or if you are unsure about what to do or how to
+get started, please write to `translation@iro.umontreal.ca' to reach the
+coordinator for all translator teams.
+
+ The English team is special. It works at improving and uniformizing
+the terminology in use. Proven linguistic skill are praised more than
+programming skill, here.
+
+Available Packages
+==================
+
+ Languages are not equally supported in all packages. The following
+matrix shows the current state of internationalization, as of August
+2002. The matrix shows, in regard of each package, for which languages
+PO files have been submitted to translation coordination, with a
+translation percentage of at least 50%.

+ Some counters in the preceding matrix are higher than the number of
+visible blocks let us expect. This is because a few extra PO files are
+used for implementing regional variants of languages, or language
+dialects.
+
+ For a PO file in the matrix above to be effective, the package to
+which it applies should also have been internationalized and
+distributed as such by its maintainer. There might be an observable
+lag between the mere existence a PO file and its wide availability in a
+distribution.
+
+ If August 2002 seems to be old, you may fetch a more recent copy of

+
+Using `gettext' in new packages
+===============================
+
+ If you are writing a freely available program and want to
+internationalize it you are welcome to use GNU `gettext' in your
+package. Of course you have to respect the GNU Library General Public
+License which covers the use of the GNU `gettext' library. This means
+in particular that even non-free programs can use `libintl' as a shared
+library, whereas only free software can use `libintl' as a static
+library or use modified versions of `libintl'.
+
+ Once the sources are changed appropriately and the setup can handle
+to use of `gettext' the only thing missing are the translations. The
+Free Translation Project is also available for packages which are not
+developed inside the GNU project. Therefore the information given above
+applies also for every other Free Software Project. Contact
+`translation@iro.umontreal.ca' to make the `.pot' files available to
+the translation teams.

+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program

+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+
+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL. It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it. You can use it for
+your libraries, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library. If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software. To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+ Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs. This
+license, the GNU Library General Public License, applies to certain
+designated libraries. This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+ The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it. Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program. However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+ Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries. We
+concluded that weaker conditions might promote sharing better.
+
+ However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves. This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them. (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.) The hope is that this
+will lead to faster development of free libraries.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+ Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License"). Each licensee is
+addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ c) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ d) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.

+ To install the second extended file system management programs,
+just follow the steps:
+
+1) Change directory into the top of the e2fsprogs source tree
+
+2) Create a build directory and cd into it:
+
+ mkdir build; cd build
+
+3) Run the configure script
+
+ ../configure
+
+ If you wish to turn on ELF shared libraries, add the option
+--enable-elf-shlibs. If you wish to build profiling libraries, add
+the option --enable-profile.
+
+ Note that if you are building on an older system (i.e., a 2.4
+kernel and/or glibc 2.2), the use of thread local storage will probably
+cause programs that use the uuid library to core dump. To disable
+thread local storage, use the configure option --disable-tls.
+
+4) Compile the programs
+
+ make
+
+5) Check to make sure the installation built correctly:
+
+ make check
+
+6) Install the programs
+
+ Run `make install'
+
+7) Install the include files and libraries
+
+ You can run `make install-libs' to install the include files and
+libraries. Please note that this installation is not needed for the
+programs to work. It is only needed if you expect to develop other
+programs using the libraries or if you want to compile other program
+using these libraries (like the 4.4BSD dump and restore port).
+
+8) Remove any pre-formatted man pages.
+
+ Some distributions will have pre-formatted manual pages which
+will always be displayed in preference to newer man pages in /usr/man.
+If this is the case, you may need to manually remove them in order to
+see the correct manual pages. The shell script in
+install-utils/remove_preformat_manpages may be helpful in doing so.
+
+9) Make sure your /etc/fstab file is correct.
+
+ Some distributions install an /etc/fstab which is missing the
+fifth and sixth field of filesystem entry, which are the dump
+frequency, and the fsck pass number, respectively. The problem with
+this is that the getmntent() library routine interprets those missing
+fields as "0", and a pass number of 0 is documented as meaning that
+fsck should not check that particular filesystem. If your entries in
+your /etc/fstab file look liks this:
+
+/dev/hda4 / ext2 defaults
+
+you should add "1 1" at the end of each line, so that they look like this:
+
+/dev/hda4 / ext2 defaults 1 1
+
+ There is a script in install-utils/convfstab (donated by
+Michael Weller) that may help you correct your /etc/fstab file.

+NOTE: This is the ELF version of the binary distribution. If you have
+a DLL system, please compile e2fsprogs from sources yourself. (In
+fact, in general you're better off compiling e2fsprogs from sources
+instead of using precompiled binaries.)
+
+Also please note that these binaries assume the use of the GNU Libc.
+If you're still using libc5, you'll need build e2fsprogs from source.
+
+ To install the binary distribution of the second extended file
+system management programs, just follow the steps:
+
+1) Install this tar file using the following command:
+
+ gunzip < e2fsprogs-1.13-elfbin.tar.gz | (cd /; tar Sxvpf - )
+
+2) Run ldconfig to update the shared library pointers.
+
+ As root, type /sbin/ldconfig. This will update the links to
+the shared libraries included in the distribution. You can then remove
+the old versions of the libraries from /lib.
+
+3) Remove any pre-formatted man pages.
+
+ Some distributions will have pre-formatted manual pages which
+will always be displayed in preference to newer man pages in /usr/man.
+If this is the case, you may need to manually remove them in order to

+/dev/hda4 / ext2 defaults 1 1
+
+ There is a script in install-utils/convfstab (donated by
+Michael Weller) that may help you correct your /etc/fstab file.
+
+5) Cleanup files from the installation.
+
+ When you're done with the installation, you will probably want
+to remove /INSTALL (this file), /README, and /install-utils from your
+root directory

+ This is the new version (1.42.13) of the second extended file

+
+ From time to time, I release new versions of e2fsprogs, to fix

+information about the latest version at the the e2fsprogs web page,
+which is:
+
+ http://e2fsprogs.sourceforge.net

+E2fsprogs 1.42.13 (May 17, 2015)
+================================
+
+Fixed a potential buffer overflow while closing a file system in
+libext2fs. (CVE-2015-1572, Addresses Debian Bug: #778948)
+
+Fixed a bug which could cause e2fsck to corrupt Hurd file systems.
+(Addresses Debian Bug: #760275)
+
+Fixed a deadlock which occurs when using systemd and e2fsck.conf's
+logging feature. (Addresses Debian Bug: #775234)
+
+Fixed a bug which could cause programs using libext2's inode table
+scanning functions from crashing on certain corrupted file systems.
+(Addresses Debian Bug: #773795)
+
+Fixed dumpe2fs so it won't crash if the user doesn't specify a block
+device (file system). (Addresses Debian Bug: #764293)
+
+Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it
+will report the correct directory inode containing the inconsistency.
+
+If e2fsck fails to grow the dir_info structure due realloc(3) not
+having enough memory, it will now fail with explanatory message
+instead of staggering on failing with a confusing internal error
+messages.
+
+The tune2fs program will zero out the superblock journal backup
+information when removing a journal from a file system.
+
+The mke2fs program now enables the large_file feature by default.
+
+Fixed a bug which could cause badblocks to crash if there are millions
+and millions of bad blocks.
+
+Fixed some use-after-free bug in resize2fs and e2fsck.
+
+Fixed a memory leak in tune2fs.
+
+Fixed some bigendian bugs that had crept into both indirect and extent
+handling inside libext2fs.
+
+Updated/fixed various man pages.
+
+Update Esperanto, German, and Spanish translations. Added Danish
+translation.
+
+Programmer's Notes
+------------------
+
+Fixed coverity, sparce gcc -Wall, and clang warnings/nits.
+
+Clean up some build system problems (build failures with various
+configure options, fix Posix portability issues, etc.)
+
+The functions ext2fs_inode_alloc_stats[2]() and
+ext2fs_block_alloc_stats[2]() now check the inode and block numbers
+passed to them, to avoid crashes caused by buggy callers.
+
+The libext2fs directory iterator will now check for an invalid
+directory entry length instead of possibly walking off the end of the
+directory buffer.
+
+
+E2fsprogs 1.42.12 (August 25, 2014)
+===================================
+
+Fix various e2fsck bugs when trying to repair bigalloc file systems.
+
+E2fsck can now repair a file system with an overly large
+s_first_meta_bg field, which had previously caused all e2fsprogs
+programs to crash when trying to open such a file system.
+
+Fix e2fsck so that it can correctly fix a number of rare file system
+corruptions that were discovered when using a file system fuzzer.
+
+Fix e2fsck so it does not try to write back block group descriptors if
+they have not been modified.
+
+Mke2fs program will now place metadata blocks in the last flex_bg so
+they are contiguous. This reduces free space fragmentation in a
+freshly created file system, as well as allowing mke2fs commands which
+request extremely large flex_bg size to succeed.
+
+Mke2fs now creates hugefiles more efficiently (with fewer extent tree
+blocks).
+
+Fix a 32/64-bit overflow bug that could cause resize2fs to loop
+forever. (Addresses-Launchpad-Bug: #1321958)
+
+The resize2fs program will now use much less memory when resizing very
+large file systems.
+
+Fix a bug which could cause resize2fs to get confused and produce a
+corrupted file system when shrinking a file system that had been
+previously expanded and converted to use the meta_bg file system
+format, but which no longer needs to use the meta_bg file system
+format any longer. This typically happened with large (> 16TB) file
+systems. (Addresses Debian Bug: #756922)
+
+The e4defrag program will now defrag backwards-allocated files.
+
+Fix tune2fs updating UUID's when manipulating file systems with
+external journals (both the file system and journal UUID).
+
+Fix tune2fs so it can remove an external journal for file systems with
+a 1k block size.
+
+Add a new debugfs command, "inode_dump", which prints the inode in hex
+and ASCII format.
+
+The debugfs's "set_inode_field" will now automatically allocate blocks
+for indirect blocks and extent tree blocks.
+
+Fix debugfs's "set_inode_field" so can properly handle
+"block[IND|DIND|TIND]".
+
+The debugfs "rdump" command will now take multiple source arguments.
+
+Fixed a double close(2) bug in "rdump" and "rdump -p".
+
+Fix debugfs's argument parsing for the freefrag command.
+
+Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
+(Addresses Launchpad Bug: #1356496)
+
+Clarified messages that were confusing users in debugfs, e2fsck,
+mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
+#757544)
+
+Dumpe2fs will now complain if extra arguments are given to it.
+(Addresses Debian Bug: #758074)
+
+Updated/fixed various man pages. (Addresses-Debian-Bug: #726760)
+
+Update Czech, Dutch, French, Polish, Spanish, Sweedish, Ukrainian, and
+Vietnamese translations.
+
+Programmer's Notes
+------------------
+
+The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
+number of system calls issued.
+
+Fixed profiled build.
+
+The libext2fs library will now more efficiently split an extent tree
+index block when appending to an end of a file.
+
+Fixed free block accounting for 64-bit file systems.
+
+Add a new function ext2s_inode_size_set() which takes care of all of
+the required feature flag modifications.
+
+The regression tests no longer require the presence of the md5sum
+program.
+
+Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
+#754605)
+
+Fix various Coverity warnings (#1225003, #1229243, #1252003)
+
+
+E2fsprogs 1.42.11 (July 9, 2014)
+================================
+
+Add support so that mke2fs can create hugefiles so that they are
+aligned relative to the beginning of the disk, instead of relative to
+the beginning of the partition, using the mke2fs.conf configuration
+parameter "hugefiles_align_disk".
+
+Fix a bug which causes e2fsck to abort a journal replay on a file
+system with bigalloc enabled. (Addresses Debian Bug: #744953)
+
+Add sanity checks so that mke2fs will refuse insanely large flex_bg
+counts specified by the -G option. Insanely large flex_bg sizes can
+result in a file system which can't be unmounted, or with extremely
+pessimal metadata layouts.
+
+The mke2fs program will provide a better metadata layout for
+moderately large (but believable) flex_bg counts, such as 133,072.
+
+The mke2fs progam will also check the kernel version number to
+determine whether the lazy_itable_init option is supported, so that
+lazy inode table initialization can be used even if the ext4 is
+compiled as a module which isn't loaded at the time that mke2fs is
+run.
+
+Add description of ext4's mount options to the ext4 section 5 man
+page.
+
+Improve the chattr man page and clean up the chattr usage message.
+
+E2fsck will now automatically fix a last mount time or last write time
+which is in the future in preen mode, instead of aborting the fsck
+check.
+
+Mke2fs will now check the file system revision number requested by the
+command line, and reject it if it is too large. A file system with an
+unsupported revision number will not be accepted by any of the other
+file system tools, and this command line option is rarely used, so
+let's try to help the user not shoot their own foot off.
+
+The debugfs progam can now set the error count and associated
+first_error and last_error fields in the superblock using the
+set_super_value command.
+
+Resize2fs will not try to calculate the minimum size of a file system
+if it contains errors. Otherwise a very badly corrupted file system
+image can cause the minimum size calculation to loop forwever. Since
+resize2fs will not allow a file system marked as containing errors to
+be resized. It's pointless to calculate the minimum size, so just
+skip it.
+
+Fixed a typo in one of mke2fs's error message.
+
+If filefrag runs into an error, it will continue processing the rest
+of the files specified on thec ommand line, but then exit with an
+error code.
+
+Filefrag now prints some additional new flags (such as
+FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
+
+Fixed support in filefrag for files with > 2**32 blocks on 32-bit
+platforms.
+
+Fixed a file descriptor leak in debugfs when copying files.
+
+Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
+to create file systems larger than 2GB on 32-bit platforms.
+(Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
+
+Add Esparanto and Ukrainian translations, and update Czech, Dutch,
+French, German, Italian, Polish, Sweedish, and Vietnamese
+translations.
+
+Fixed various compiler warnings.
+
+
+Programmer's Notes
+------------------
+
+The gcc "-checker" option has been long deprecated, so remove support
+from e2fsprogs. It was causing a few people to be confused when they
+tried enabling the configure option.
+
+Update to the latest version of the config.status and config.rpath
+files, as well as newer versions of the autoconf files in aclocal.m4.
+Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
+people who want to use autoreconf to do so.
+
+Make the use of strptime() function in debugfs to be more portable to
+fix regression test failures for FreeBSD and MacOS.
+
+A few miscellaneous changes designed to make life easier for
+translators.
+
+Fix the f_quota test and some Makefile dependencies if quota support
+is not enabled.
+
+Fix cross-compilation support, which got broken in 1.42.10.
+(Addresses Debian Bug: #753375)
+
+Delete lib/ext2_types.h on a make clean, and build it as necessary.
+
+Add a debug program used for libext2fs unit tests.
+
+Clean up the tests so that it avoids using GNU-specific behaviour in
+mktemp. Make sure the temporary files are cleaned up if the tests are
+interrupted.
+
+Add a new ext2fs_close_free() helper function which automatically
+takes care of freeing the ext2_filsys structure even if ext2fs_close()
+returns an error.
+
+
+E2fsprogs 1.42.10 (May 18, 2014)
+================================
+
+Mke2fs now creates file systems in regular files (which is very often
+used when maintaining virtual machine images) without requiring the
+user to use the force option. In addition, the mke2fs output has been
+made much less verbose and only displays information that users will
+be more likely to find useful by default.
+
+Mke2fs now will ask the user to confirm that they want to continue
+before wiping out a pre-existing file system, partition table, or LVM
+physical volume.
+
+Mke2fs now has the ability to create file systems where all the
+metadata is located at the very beginning of the device. This can be
+useful for flash devices which have SLC flash at the beginning of the
+disk, for FAT compatibility, for example. As part of this, mke2fs and
+tune2fs can control the location of the data blocks used by the
+journal inode. In addition, the new sparse_super2 feature allows for
+even fewer (anywhere from zero to two) backup superblocks.
+
+Mke2fs now uses much less CPU when allocating the blocks used for very
+large file systems.
+
+Mke2fs can now support creating a file system at an offset. This can
+be useful when creating a disk image for virtual machines (Addresses
+Debian Bug: #497984)
+
+Previously, e2fsck had a number of very serious bugs when checking a
+file system wich used the new the quota file system option (where the
+quota inodes were stored in hidden inodes) and the quota inode was
+inconsistent with the actual usage data. This problem was documented
+in https://ext4.wiki.kernel.org/index.php/Quota. These problems have
+been fixed in 1.42.10, so the quota should be safe to use with
+e2fsprogs 1.42.10.
+
+Fixed in a bug in resize2fs which could cause shrink operation fail in
+the unlikely situation when the inode table needs to be moved to a
+location before the current location.
+
+Resize2fs now has a much more accurate (and less conservative)
+estimation of how far the file system can be shrunk. This allows a
+mostly empty filesystem which is a few terabytes, to be shrunk to a
+few megabytes in a single resize2fs -M operation.
+
+E2fsck will now force a full file system check if there are any file
+system inconsistencies detected in the super block.
+
+The filefrag program will now display hte shared extent flag, which is
+used by file systems such as btrfs.
+
+If the number of inodes in the file systems is larger than the time
+that file sytem was created (as measured by the number of seconds
+since January 1, 1970) e2fsck would print a scary (but otherwise
+harmless) warning of file system corruption for each inode in the
+orphan list. This false positive has been fixed.
+
+The e4defrag program has been fixed so it will no longer refuse with
+filesystem with the 64-bit or the bigalloc feature enabled.
+
+The logsave progam will print a much less scary message which could
+lead users to believe something has gone very wrong with e2fsck exits
+with a non-zero exit status (since this is normal after e2fsck has
+automatically fixed a file system corruption during a preen
+operation). (Addresses Debian Bug: #468821)
+
+When creating a file system which is larger than 16TB, the
+resize_inode option must be disabled -- since the resize_inode simply
+doesn't support reserving metadata block numbers which is larger than
+32 bits. The mke2fs program does this automatically if the file
+system size is determined automatically. It will now also do this if
+the file size is specified explicitly.
+
+Fixed bugs associated with resize2fs and shrinking bigalloc file
+systems.
+
+The e2fsck program will no longer try to add a UUID on a mounted file
+system with checksums enabled, since this could leave the file system
+checksums broken.
+
+Tune2fs will allow the removal of an external journal from file system
+which is marked as needing the journal replayed when the force ("-f")
+option is given twice. (Addresses Debian Bug: #559301)
+
+Tune2fs will no longer support enabling sparse_super if the meta_bg
+file system feature is enabled, since it could result in data loss.
+In practice, all modern file systems have sparse_super is enabled, so
+it's not worth trying to change how tune2fs handles enabling the
+sparse_super feature.
+
+Fixed support for 1k block file systems with the meta_bg feature.
+
+When the superblock is corrupt, e2fsck can't figure out the location
+of the alternate superblock. Unfortunately, the routine that
+calculates the location of the alternate superblock uses 8193 if it
+can't figure this out, so the message printed by e2fsck always
+suggests using "e2fsck -b 8193". This message has been fixed to
+suggest both the superblock location of 8193 and and 32768.
+(Addresses Debian Bug: #719185)
+
+The lookback mount detection code that was introduced in 1.42.9 wasn't
+actually compiled in due to an autoconf oops, so it's fixed now in
+1.42.10. (Addresses Debian Bug: #497984)
+
+A bug introduced in 1.42.9 would cause debugfs to print two error
+messages if it found an error while parsing a user-supplied block
+number. This has been fixed in 1.42.10.
+
+Update Czech, Dutch, French, German, Polish, Spanish, Sweedish, and
+Vietnamese translations. (Addresses Debian Bug: #703048)
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #719189,
+#719184)
+
+Fixed various Debian Packaging Issues. (Addresses Debian Bug: #718725)
+
+
+Programmer's Notes
+------------------
+
+Fixed a lot of coverity, sparce gcc -Wall, and clang warnings/nits.
+
+Allow the location of pkg-config files to be specified independent of
+the libdir location via a makefile variable.
+
+Fixed parse-types.sh not to complain when cross-compiling and the
+sizes of types are different between the target architecture and the
+architecture of the build system
+
+Allow the regression test suite to work correctly on systems which do
+not have the "truncate" or "mksawp" programs.
+
+Allow e2fsck to build correctly on systems (such as Android) that do
+not have the signal.h file.
+
+E2fsprogs now has code coverage testing which can be enbled using
+"configure --enable-gcov".
+
+The libe2p.h header file can now be used included by C++ programs.
+
+The profile/config file used by e2fsck and mke2fs will interpret
+numbers with a leading 0 character to mean that they should be
+interpreted as an octal integer.
+
+The extent handling functions in libext2fs have been improved so they
+have proper rollback when there is an error splitting an extent. Also
+fix a number of bugs when punching holes in files, and fix an
+off-by-one bug when inserting an extent into an empty inode.
+
+The libext2fs library now handles the support of BLOCK_UNINIT by
+clearing the portion of block bitmap when it is loaded, instead of
+when it is used. This reduces the chances of bugs, and and simplifies
+the code. It also means that debugfs will properly show that blocks
+in uninitialized block groups as being unused when using the testb
+command.
+
+The e4defrag program will try to use fadvise64 or posix_fadvise64() if
+it is present, which allows 64-bit offsets on 32-bit systems.
+
+
+E2fsprogs 1.42.9 (December 28, 2013)
+====================================
+
+Mke2fs will detect an attempt to create a file system on a loop
+mounted file and complain without the -FF option. Also fixed mke2fs
+so it allows the creation of a file system on a mounted device with
+two -F options, as documented in the man page, instead of three -F
+options.
+
+Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
+libext2fs to correctly handle bigalloc and 64-bit file systems. There
+were many corner cases that had not been noticed in previous uses of
+these file systems, since they are not as common. Some of the bugs
+could cause file system corruption or data loss, so users of 64-bit or
+bigalloc file systems are strongly urged to upgrade to e2fsprogs
+1.42.9.
+
+The tune2fs program will now not allow changing the uuid on a mounted
+file system which has the uninit_bg feature enabled. This avoids a
+nasty race where the kernel and tune2fs are both retrying rewrite the
+group descriptors at the same time, with different ideas about what
+the UUID should be.
+
+When e2fsck is rehashing an extent-mapped directory, it's possible
+(although very rare) that an extent block will need to be allocated;
+fix e2fsck to make sure that the block gets marked as used.
+
+Mke2fs will now properly set the LARGE_FILE feature when creating a
+journal >= 2GB --- which can happen when using 64k block size.
+
+Fixed debugfs so that its freei command will correctly handle a request
+to free a range of consecutive inodes.
+
+Fixed 2fsck so it will not erroneously complain that an external journal
+is invalid if it is exactly 2**32 blocks.
+
+Fixed e2fsck so it won't try checking for, and adding, a missing
+lost+found directory when running in read-only mode.
+
+Fixed e2image to avoid some buffer overruns which would cause it to when
+creating a "standard (non-raw, non-qcow2) image file. Standard
+e2image files are actually very rarely used, so we didn't notice when
+the changes to enable the qcow2 format broke this e2image mode.
+
+Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
+on the resize_inode feature when the meta_bg feature is set, since
+these two features can not be set at the same time.
+
+Fixed tune2fs so that when it disables the quota feature, it updates all
+of the backup superblocks.
+
+Fixed dumpe2fs that would cause it to abort when run using an image file
+when trying to print the journal information (which is not present in
+an e2image created image file).
+
+Fixed a potential integer overflow in e2reefrag.
+(Addresses-Debian-Bug: #718205)
+
+Enhance debugfs so that when copying a sparse file from a native file
+system into the file system image using the "write" command, it will
+create a sparse file into the destination file system.
+
+Enhanced debugfs so it can support a command line which is up to 8k
+long.
+
+E2image will refuse (unless the -f option is specified to force the
+issue) to create a raw or qcow image using a mounted file system,
+unless the -f option is specified to force the issue.
+
+E2image has been optimized for using it to efficiently copy a file
+system by only copying the allocated blocks, by using the options -ra.
+New options (-o and -O) have been added so that a source and
+destination offset can be given. The -p option will print progress
+information so the user will know how far along the copy is going.
+And finally, the new option -c is useful for updating a file system on
+an SSD, by avoiding unnecessary writes. E2image can also shift a file
+system image by doing an in place move.
+
+Fix a regression introduced in 1.42.8 which would cause e2fsck to
+erroneously report uninitialized extents past the EOF (as determined by
+i_size) to be invalid.
+
+Fixed resize2fs so under a corner case when an inode has a complex
+extent tree, it will not corrupt an interior node in the extent tree.
+
+Fixed resize2fs which would sometimes corrupt a file system when
+shrinking a file system to a minimum size using resize2fs -M.
+(Addresses Debian Bug: #660793)
+
+Fixed resize2fs so that it will relocate inode table blocks if this
+becomes necessary when shrinking the file system.
+
+Fixed resize2fs and e2fsck so they will not crash when hit a failure
+while operating on a file system with the MMP feature enabled.
+
+Fixed a bug in debugfs which caused it create an invalid inode when
+trying to write a zero-length file.
+
+E2fsck will no longer crash if it tries to delete an invalid
+extent-mapped symlink.
+
+E2fsck will no longer crash if it comes across an directory which is
+larger than 2GB (which is not allowed in valid file systems).
+
+Fixed debugfs's help texts to fully document all options and otherwise
+be more helpful.
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #586218,
+#669730, #698076)
+
+Fixed various Debian Packaging Issues (#698879, #721365)
+
+
+Programmer's Notes
+------------------
+
+Fix sparse, gcc -Wall and clang nits.
+
+Update config.{guess,sub} to the latest version
+
+Fixed various memory and file descriptor leaks on various error paths,
+as well as some missing error return checks, which were found using
+Coverity.
+
+Run sparse against source files when building e2fsprogs with 'make
+C=1'. If instead C=2, it configures basic ext2 types for bitwise
+checking with sparse, which can help find the (many many) spots where
+conversion errors are (possibly) happening.
+
+Allow the regression test to be run in chrooted environments where
+/etc/mtab might be missing.
+
+The ext2fs_punch() function, which was introduced in 1.42, was broken
+in many ways, but this was never noticed since it wasn't used for
+anything significant. Some of the bugs include failing when trying to
+punch a completely sparse file, failing when punching an extent-mapped
+inode when the starting block was at the beginning of the inode, and
+not being able to punch a single block (where start_blk == end_block).
+It also didn't handle being passed an invalid, too-large ending block
+number, and didn't handle properly terminate at the right place when
+operating on an indirect-mapped inode.
+
+Fixed some minor typo's in the error catalog for libext2fs.
+
+Fixed ext2fs_file_set_size2() so that if it truncates an inode by
+setting the file size, to zero the rest of the block to the end of the
+file, so that if an ext4 FUSE driver tries to extended the file, that
+we don't avoid stale data from being returned.
+
+Fixed ext2fs_bmap() to disallow clients from trying to map or set
+logical blocks which are larger than what an extent-mapped or indirect
+block-mapped inode can allow.
+
+If debugfs (or some userspace program using libext2fs) creates a file
+which is larger than 2GB, make sure the large_file feature flag gets
+set.
+
+Fix a bug in ext2fs_link() where if there is multiple empty slots in the
+directory which are large enough, the directory entry could get
+inserted more than once in the directory.
+
+If quota support is disabled (which is the default), make sure that
+all traces of the quota support is removed from usage messages, man
+pages, and tune2fs must not be able to enable the quota file system
+feature. (Addresses Red Hat Bugzilla: #1010709)
+
+The ext2fs_file_write() now updates i_size on a successful write,
+instead of only updating i_size wen the file is closed via
+ext2fs_file_close().
+
+Added a shell script, populate-extfs.sh which uses debugfs to populate
+an ext2/3/4 file system image from a given directory. It is similar
+to the genext2fs program, but it supports ext3 and ext4 file system.
+
+Add changes to the libext2fs library to support block group
+descriptors larger than 64 bytes (for future compatibility).
+
+Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
+leave an extra block in the file when truncating the file down to
+size.
+
+The html version info pages are now built using makeinfo --html
+instead of the unmaintained and now-obsolete texi2html program.
+
+
+E2fsprogs 1.42.8 (June 20, 2013)
+================================
+
+As a part of mke2fs's option parsing cleanup, the use of the -R option
+will give a warning that it is depreated (it has been so documented
+since 2005) and -E should be used instead.
+
+Mke2fs will not give warnings about the bigalloc and quota options in
+quiet mode.
+
+If an invalid journal size is given to mke2fs, it will now complain
+and exit sooner.
+
+Debugfs was erroneously giving spurious error messages for certain
+extent_inode subcommands which take arguments (split_node,
+replace_node, and insert_node). This has been fixed.
+
+Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
+other programs is used by mke2fs.
+
+Change mke2fs so that it does not set the root directory to the real
+uid/gid of the mke2fs process. Add the extended option root_owner to
+override this behavior.
+
+Fix resize2fs when shrinking file systems to make sure that bitmap
+blocks aren't left outside the bounds of the shrunken file system.
+This could happen with flex_bg file systems that were grown using
+the old online resizing algorithm.
+
+E2fsck will now detect and repair corrupted extent trees which contain
+invalid extents at the end of the extent tree leaf block.
+
+E2fsck will now longer complain about zero length extended attribute
+values.
+
+Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
+to crash.
+
+Add safety check so tune2fs will not attempt to set the inode size to
+be larger than the block size.
+
+Fix e2fsck so it can check a read-only root file system with an
+external journal. (Addresses Debian Bug: #707030

+Programmer's Notes
+------------------
+
+Use secure_getenv() in preference to __secure_getenv().
+
+Optimize CPU utilization of ext2fs_bg_has_super().
+
+Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
+SEEK_CUR is used with large files.
+
+The ext2fs_read_inode_full() function will no longer use
+fs->read_inode() if the caller has requested more than the base 128
+byte inode structure and the inode size is greater than 128 bytes.
+
+Fix build failure with --enable-jbd-debug.
+
+Clean up filtering of outputs for the regression tests by using a

+
+Fix gcc -Wall and clang nits.
+
+
+E2fsprogs 1.42.7 (January 21, 2013)
+===================================
+
+Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
+quota features are still under development. For more information
+please see:
+ * https://ext4.wiki.kernel.org/index.php/Bigalloc
+ * https://ext4.wiki.kernel.org/index.php/Quota
+
+Add some new options to filefrag from Lustre's patches to e2fsprogs:
+ * add -k option to print extents in kB-sized units (like df -k)
+ * add -b {blocksize} to print extents in blocksize units
+ * add -e option to print extent format, even when FIBMAP is used
+ * add -X option to print extents in hexadecimal format
+
+Fix resize2fs so that it can handle off-line resizes of file systems
+with the flex_bg feature but without a resize_inode (or if we run out
+of reserved gdt blocks). This also fixes a problem where if the user
+creates a filesystem with a restricted number of reserved gdt blocks,
+an off-line resize which grows the file system could potentially
+result in file system corruption.
+
+Fix a resize2fs bug which could cause it to corrupt bigalloc file
+systems when doing an off-line resize.
+
+Further optimize resize2fs so it doesn't use quite as much CPU when
+resizing very large file systems.
+
+Fixed 32-bit overflow bugs which could cause resize2fs to fail and
+possibly corrupt the file system while resizing 64-bit file systems.
+
+Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
+mke2fs crash due to a divide-by-zero if the 64bit file system feature
+is enabled.
+
+Add better error checking to mke2fs to check for invalid parameters
+when creating bigalloc file system.
+
+When creating bigalloc filesystems, the -g option to mke2fs will now
+specify the number of clusters per block group.
+
+Add to debugfs the functionality to corrupt a specific file system
+block via the "zap_block" command.
+
+Add to debugfs the functionality to print out a hex dump of a block in
+the file system via the "block_dump" command.
+
+Add to debugfs the functionality to manipulate the extent tree
+directly via the "extent_open" command.
+
+Fixed debugfs's mknod command so that it updates the block group
+statistics.
+
+Fix e2fsck so it can detect and fix inconsistencies in the interior
+nodes of an inode's extent tree.
+
+Fix a potential memory corruption failure in e2fsck's error path if
+the call to ext2fs_open2() fails.
+
+Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
+resulting file name for the log file is longer than 100 bytes, that it
+properly handles this situation instead of crashing.
+
+E2fsck will now report the amount of memory that it attempted to
+allocate when a memory allocation request fails, to make it easier to
+track down the problem.
+
+Fix mke2fs's handling of the mmp_update_interval option. (Addresses
+Lustre Bug: LU-1888)
+
+E2image can now include all data blocks in the e2image output file
+when the user specifies the -a option.
+
+If e2fsprogs is compiled without --enable-quota, make sure that
+tune2fs can not turn on the feature for new-style quota support, since
+afterwards, none of the e2fsprogs tools will be willing to touch that
+file system.
+
+Optimize e2fsck's so that it uses much less CPU for large file
+systems. This can result in significant speedups, especially on
+CPU-constrained systems. This was primarily done by optimizing
+libext2fs's bitmap functions. (Addresses Google Bug: #7534813)
+
+Fix debugfs's htree command so that all its messages are sent through
+the pager.
+
+Fixed debugfs's "dump_file" and "cat" functions work correctly
+on file systems whose block size is greater than 8k.
+
+Fix e2freefrag so it works on 64-bit file systems, and so it uses much
+less memory. (Addresses Google Bug: 7269948)
+
+Update the spd_readdir.c file in the contrib directory to include some
+additions which were made in 2008 that didn't get folded into the
+version which we checked into the e2fsprogs source tree. These
+enhancements include thread safety, support for readdir64_r(), and
+safe_getenv() support in case spd_readdir.so is used for setuid binaries.
+
+Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
+translations
+
+Add a command to debugfs to create symlinks.
+
+Document the bigalloc feature in the mke2fs man page. (Addresses
+Debian Bug: #669730)
+
+
+Programmer's Notes
+------------------
+
+Fix gcc -Wall nits.
+
+Fix a spelling typo in the libext2fs texinfo documentation.
+
+Change the output from "make check" so that tools such as emacs's "M-x
+compile" does not mistake the output as containing a compiler error.
+
+Export two new functions from libext2fs: ext2fs_extent_node_split()
+and ext2fs_extent_goto2().
+
+The ext2fs_extents_fix_parents() was fixed so it does not modify the
+location of the extent handle if its current location is at an
+interior node, rather than a leaf node of an inode's extent tree.
+
+Add a regression test to assure that e2fsck can correctly fix an
+inconsistent interior node in an inode's extent tree.
+
+The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
+correctly support bigalloc file systems which use store block usage
+information in units of clusters.
+
+Fixed the help text in the configure script for --enable-quota.
+
+The m68k-specific bitops code has been removed since they were
+incorrectly treating bit numbers with the high bit set as signed
+integers. Furthermore, modern compilers do a good enough job
+optimizing the generic code there is no point in having the m68k
+specific asm statements.
+
+Fixed how we link the test programs so they always use the static
+libraries, so that we test using the libraries which we have just
+built.
+
+Update config.guess and config.sub to the latest versions from the GNU
+project.
+
+Fixed the com_err.texinfo file so that it can produce a valid
+postscript/pdf printed output.
+
+Add a regression test which checks debugfs's ability to create
+symlinks, named FIFO's, and device nodes.
+
+Add a function ext2fs_symlink(), which creates symlinks to the
+libext2fs library.
+
+Add debugging code so we can test old kernel interfaces for online
+resize to resize2fs. This backwards compatibility checking is keyed
+off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
+test the functionality of the kernel's older resize ioctls without
+needing to install an old version of resize2fs, and to also test a
+modern resize2fs's ability to work with older kernels without having
+to install an older version of the kernel.
+
+
+E2fsprogs 1.42.6 (September 21, 2012)
+=====================================
+
+When mke2fs creates file systems with lazy itable initialization, the
+progress updates for writing the inode table happens so quickly that
+on a serial console, the time to write the progress updates can be the
+bottleneck. So mke2fs will now only update its progress indicators
+once a second.
+
+Resize2fs will skip initializing the inode tables if the kernel
+supports lazy_itable_init, which speeds up growing off-line growth of
+uninit_bg file systems significantly. Resize2fs will now also
+correctly set the itable_unused field in the block group descriptor to
+speed up the first e2fsck after the file system is grown.
+
+Resize2fs has been fixed so that on-line resizing of meta_bg file
+systems work correctly. This is needed to grow file system which are
+larger than 16T.
+
+Resize2fs will now correctly handle resizing file systems to 16TB on
+32-bit file systems when "16TB" is specified on the command line.
+
+Fix mke2fs so that it will be careful to set the reserved blocks ratio
+larger than 50%; this can happen when creating small file systems and
+when the last block group is dropped because there are not enough
+blocks to support the metadata blocks in the last block group.
+
+Fixed spelling mistake in debugfs's help message.
+
+Fixed a potential seg fault in e2fsck when there is an I/O error while
+reading the superblock.
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
+
+Updated/fixed various man pages. (Addresses Sourceforge Bug:
+#3559210)
+
+Programmer's Notes
+------------------
+
+The configure option --enable-relative-symlink was broken so that it
+needed to be --enable-symlink-relative-symlinks. We will support both
+for at least two years, but then the worng configure option will be
+removed.
+
+Fixed a regression introduced in 1.42.5 so the link order for
+e2fsprogs' libraries will be correct for both static and shared
+linking. (Addresses Sourceforge Bug: #3554345)
+
+Add support for e2fsprogs to be compiled using clang/LLVM.
+
+Fix portability problems on non-Linux systems: avoid compile failures
+on systems that don't have malloc.h
+
+Fix f_mmp regression test suite so that debugfs gets killed if the
+test is interrupted.
+
+
+
+E2fsprogs 1.42.5 (July 29, 2012)
+================================
+
+Fixed a bug with mke2fs where if there is only 8 inodes per block
+group, the calculation of the number of uninitialized inodes in the
+first block group would go negative. This resulted in "mke2fs -N 256
+-t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
+would run out of space. (Addresses Sourceforge Bug: #3528892)
+
+Fixed a bug in how e2fsck would uniquify directory entry names.
+(AddressesSourceforge Bug: #3540545)
+
+Previously, e2fsck would only allow a mounted file system to be
+checked if it was the root file system and it was mounted read-only.
+Now it will allow any file system mounted read-only to be checked if
+the -f option is specified. This makes it easier to test how e2fsck
+handles checking file systems which are mounted without having to test
+on the root file system.
+
+Fixed a problem if e2fsck where if the root file system is mounted
+read-only, e2fsck would not clear an error indication in the journal
+superblock. Combined with a kernel bug, this would cause the e2fsck
+to check the file system after every single boot.
+
+The e4defrag program can now handle device symlinks, such as
+/dev/mapper/testvg-testlv, instead of insisting on a less
+human-friendly name such as /dev/dm-2. (Addresses Red Hat Bugzilla:
+#707209)
+
+Fixed filefrag so it will not crash with a segfault on files from a
+virtual file system such as /proc. (e.g., "filefrag
+/proc/partitions")
+
+Fixed filefrag so that it correctly reports the number of extents.
+(Addresses Red Hat Bugzilla: #840848)
+
+Fixed a file descriptor leak in logsave which could cause it to hang.
+(Addresses Debian Bug: #682592)
+
+Fixed e2fsck so that the file system is marked as containing an error
+if the user chooses not to fix the quota usage information.
+
+Fixed tune2fs so that it correctly removes the quota feature when the
+last quota inode is removed.
+
+Fix tune2fs so that after removing a quota inode, the block bitmap is
+updated; otherwise, e2fsck would complain after running 'tune2fs -O
+^quota <dev>'.
+
+Fix tune2fs so that when converting a file system from using legacy
+quota files to the new quota file system feature with hidden quota
+files, the accounting for these files is handled correctly so that
+e2fsck doesn't complain.
+
+Improved e2fsck's verbose reporting statistics, and allow the more
+verbose reporting to be enabled via /etc/e2fsck.conf.
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #680114)
+
+
+Programmer's Notes
+------------------
+
+Fixed portability problems on other operating systems (e.g., Hurd and
+FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
+
+Make sure that shared libraries link with the shared libraries built
+in the build tree, instead of the system provided libraries.
+Previously, libraries and executables were linked with the system
+libraries if present, and possibly using static archives instead of
+shared libraries. This was also problematic since if libext2fs.so is
+linked with a static libcom_err.a from system, the build system would
+attempt to link without -lpthread. (Addresses Sourceforge Bug:
+#3542572)
+
+
+E2fsprogs 1.42.4 (June 12, 2012)
+================================
+
+Fixed more 64-bit block number bugs (which could end up corrupting
+file systems!) in e2fsck, debugfs, and libext2fs.
+
+Fixed e2fsck's handling of the journal's s_errno field. E2fsck was
+not properly propagating the journal's s_errno field to the superblock
+field; it was not checking this field if the journal had already been
+replayed, and if the journal *was* being replayed, the "error bit"
+wasn't getting flushed out to disk.
+
+Fixed a false positive complaint by e2fsck if all of the extents in
+the last extent tree block are uninitalized and located after the end
+of the file as defined by i_size.
+
+The dumpe2fs will now display the journal's s_errno field if it is
+non-zero, and it will also display the journal's 64-bit feature flag
+if present.
+
+Fix e2fsck so that it always opens the device file in exclusive mode
+when it might need to modify the file system, and never if the -n
+option is specified. (Previously, there were a few corner cases where
+it might get things wrong in either direction.)
+
+E2fsck now correctly truncates or deallocates extent-mapped inodes on
+the orphan list. The root cause was a bug in libext2fs's block
+iterator which could end up skipping an extent when the last block in
+an extent is removed, causing the current extent to be removed from
+the extent tree.
+
+E2fsck now correctly sets the global free block and inode counts when
+truncating or removing inodes on the orphan list in preen mode.
+Previously, it would leave these values would be set incorrectly,
+which is largely a cosmetic issue since the kernel no longer pays
+attention to those fields, but it can cause spurious complaints in
+subsequent e2fsck runs.
+
+Fix i_blocks accounting when the libext2fs library needs to add or
+remove an extent tree block on bigalloc file systems.
+
+The lsattr and chattr programs now support the No_COW flag for the
+benefit of btrfs.
+
+Debugfs now interprets date strings of the form @ddd as ddd seconds
+after the beginning of the epoch. This is handy when setting an inode
+number into the d_time field when debugging orphan list handling.
+
+Fix a precedence bug with built-in quota support which might result in
+e2fsck paying attention to the quota inode field even if the built-in
+quota feature flag is not set. Fortunately, in practice that
+superblock field should be zero for non-built-in quota file systems,
+so it's unlikely this bug would have caused problems.
+
+Updated/fixed various man pages. (Addresses Debian Bugs: #674453,
+#674694)
+
+Programmer's Notes
+------------------
+
+The regression test suite can now run the integration tests in the
+tests directory in parallel, via "make -jN check".
+
+Add new test, f_zero_extent_length which tests e2fsck's handling of
+the case where all of the extents in the last extent tree block are
+uninitialized extents after i_size.
+
+Add a new test, f_jnl_errno, which checks handling of an error
+indication set in the journal superblock.
+
+Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
+of a 64-bit journal.
+
+Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
+tests e2fsck's handling of orphan inodes in preen mode, and truncation
+of extent inodes on the orphan list.
+
+Fixed more OS X portability issues.
+
+
+E2fsprogs 1.42.3 (May 14, 2012)
+===============================
+
+Fix a bug in the Unix I/O manager which could cause corruption of file
+systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
+(i.e., when unsigned long is 32-bits). Also fix a bug which caused
+dumpe2fs to incorrectly display block numbers > 32-bits.
+
+Improve the support for integrated quota files (where quota is a first
+class supported feature using hidden files in the ext4 file system).
+Previously the quota file was getting rewritten even when it was not
+necessary, and e2fsck would erroneously try to hide quota files which
+were already hidden.
+
+Quiet complaints in e2fsck when the total free blocks or inodes are
+incorrect in the superblock after an system crash, since we don't
+update nor depend on the superblock summaries at each commit boundary.
+
+Fixed a regression introduced in 1.42.2 which would cause applications
+outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
+would were still using the legacy 32-bit bitmaps) to crash. This was
+due to missing 32-bit compat code in side the function
+ext2fs_find_first_zero_generic_bmap(). (Addresses Red Hat Bugzilla:
+#808421)
+
+Fix a bug which would cause mke2fs to fail creating the journal if
+/etc/mtab and /proc/mounts are missing. (Addresses Sourceforge Bug:
+#3509398)
+
+Updated/fixed various man pages.
+
+Update Czech, Dutch, French, German, Polish, Sweedish, and Vietnamese
+translations
+
+Fixed various Debian Packaging issues.
+
+
+Programmer's Notes
+------------------
+
+Change the nonsensically wrong types in the function signature of the
+inline function ext2fs_find_first_zero_block_bitmap2(). This was
+caused by a cut and paste error; fortunately no code in e2fsprogs used
+this inline function, and there are any users of this functions
+outside of e2fsprogs.
+
+Add support for systems which have valloc(), but which do have
+posix_memalign() nor memalign() (such as MacOS 10.5).
+
+Refactor and clean up the allocation of aligned buffers for Direct I/O
+support. Previously some allocations were requesting a greater
+alignment factor that what was strictly necessary. Also optimize
+reading and writing bitmaps using Direct I/O when the size of the
+bitmap did not fully cover the file system blocksize.
+
+Reserve the codepoints for the INCOMPAT features LARGEDATA and
+INLINEDATA.
+
+Improved the regression test suite by adding some new integration
+tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
+jbd2 format, as well as f_eofblocks which tests the new handling of
+uninitialized and initialized blocks beyond i_size. Also add a new
+unit test which verifies 32-bit bitmaps support and the new
+find_first_zero primitives.
+
+Add a few dependencies to fix parallel (make -j) builds.
+
+Removed bash'isms which were breaking the regression test suite on
+systems where /bin/sh is not bash.
+
+The config.guess and config.sub have been updated to the 2012-02-10
+version.
+
+Fix a portability problem caused by assuming the present of mntent.h
+means that setmntent() exists. Instead, explicitly test for this in
+the configure script.
+
+If the sys/signal.h header file does not exist, don't try to include
+it, since it's not available on all systems.
+
+Add support for systems that do not support getpwuid_r()
+
+The configure script now supports a new option,
+--enable-relative-symlinks, which will install relative symlinks for
+the ELF shared library files. (Addresses Sourceforge Bug: #3520767).
+
+When building BSD shared libraries make sure the LDFLAGS variable is
+passed to the linker. Fixing this allows, for example, e2fsprogs to
+be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
+#3517272)
+
+Fix gcc -Wall nitpicks
+
+
+E2fsprogs 1.42.2 (March 27, 2012)
+=================================
+
+The resize2fs program uses much less CPU and is much faster for very
+large file systems. (Addresses Debian Bug: #663237)
+
+The seti and freei commands in debugfs can now take an optional length
+argument to set and clear a contiguous range of inodes.
+
+E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
+plan to remove support for it from the kernel file system driver. It
+really wasn't very useful and was causing more problems than it
+solves. Since e2fsck will complain if inodes that should have
+EOFBLOCKS_FL do not have the flag set, we are going to remove this
+check from e2fsprogs first, and then only remove the flag from the
+kernel much later.
+
+The mke2fs program can now use direct I/O via "mke2fs -D". This will
+slow down the mke2fs, but it makes it more polite on a loaded server
+by limiting the amount of memory that gets dirtied by mke2fs when it
+is using buffered I/O.
+
+E2fsck was needlessly closing and re-opening the file system as a side
+effect of adding Multiple Mount Protection (MMP). This isn't
+necessary for non-MMP file systems, so drop it.
+
+Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
+can more easily diagnose memory allocation failures caused by
+insufficient memory. E2fsck will now abort if there are memory
+allocation failures when the file system is initially opened and
+during the block group descriptor checks. (Addresses Google Bug:
+#6208183)
+
+If there are incorrect block group checks, e2fsck will now report the
+incorrect and corrected checksum values.
+
+The e2fsck progam can now write log files containing the details of
+the problems that were found and fixed directly, via configuration
+parameters in /etc/e2fsck.conf.
+
+Added the ability to limit the number of messages reported by e2fsck
+for a given problem type. This avoids a potential bottleneck if there
+is a serial console which can cause a boot sequence to take a long
+time if e2fsck needs to report many, many file system errors.
+
+The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
+them to use much less memory for large file systems.
+
+The dumpe2fs program will now print the expected block group checksum
+if it is incorrect. This helps to diagnose problems caused by
+incorrect block group checksums.
+
+E2fsck now checks for extents with a zero length, since the kernel
+will oops if it comes accross such a corrupted data structure. (See
+https://bugzilla.kernel.org/show_bug.cgi?id=42859)
+
+E2fsck has a number of bugs relating to discard that have been fixed.
+(1) Fixed a bug which could cause e2fsck to discard portions of the
+inode table which were actually in use. (2) E2fsck will now avoid
+using discard if the block device doesn't zero data on discard, since
+otherwise this could cause problems if the file system gets corrupted
+in the future. (3) E2fsck will now avoid using discard when it is run
+in read-only mode. (4) Fixed a bug which caused e2fsck to not issue
+discards in the last block group.
+
+E2fsck's CPU utilization in pass 5 has been optimized, which will
+speed up e2fsck slightly.
+
+E2image will now skip copying uninitialized bitmap and inode table
+blocks.
+
+Fixed mke2fs -S so it does not corrupt the first block group's
+information.
+
+E2fsck will now check the new sysfs interface to determine if we are
+using the battery or AC mains. (Addresses SourceForge Bug: #3439277)
+
+Updated/fixed various man pages. (Addresses Debian Bug: #665427)
+
+Fixed various Debian Packaging issues. (Addresses Debian Bug: #665885)
+
+Programmer's Notes
+------------------
+
+Fixed various portability issues for non-Linux systems, particularly
+MacOS X, as well as Linux systems running with the just-released glibc
+2.15.
+
+Fix file descriptor leak in ext2fs_close() if the file system with
+uninit_bg is opened read/only with a backup superblock. (Addresses
+SourceForge Bug: #3444351)
+
+Fixed an invalid return in a non-void function in the quota code.
+(Addresses SourceForge Bug: #3468423)
+
+Fixed the debian rules file so that the calls to dpkg-buildflags works
+when the shell is dash.
+
+The debian package build now uses V=1 so that there is more
+information about potential build failures in debian buildd logs.
+
+If the uninit flags get cleared by functions such as
+ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
+superblock is marked dirty and the block group descriptor checksum is
+updated if necessary.
+
+The debian rules file will now try to load debian/rules.custom of it
+exists. This flie can skip various builds for speed reasons if there
+is no need for the e2fsck-static or udeb packages. Available
+customizations in the rules file includes SKIP_STATIC=yes,
+SKIP_BF=yes, and SKIP_DIETLIBC=yes.
+
+In addition, if the file misc/mke2fs.conf.custom.in exists in the
+source tree, it will be used instead of the standard misc.conf file in
+the upstream sources. This makes it easier for Debian-derived systems
+to distribute a custom mke2fs.conf file without having to worry about
+merge issues if future versions of e2fsprogs makes changes in the
+upstream default version of mke2fs.conf.
+
+
+E2fsprogs 1.42.1 (February 17, 2012)
+===================================
+
+The mke2fs and e2fsck now use significantly less memory when creating
+or checking very large file systems. This was enabled by adding
+extent-based bitmaps which are stored using a red-block tree, since
+block and inode allocations tend to be contiguous.
+
+The command mke2fs -S is used as a last ditch recovery command to
+write new superblock and block group descriptors, but _not_ to destroy
+the inode table in hopes of recovering from a badly corrupted file
+system. So if the uninit_bg feature is enabled, mke2fs -S will now
+set the unused inodes count field to zero. Otherwise, e2fsck -fy
+after using mke2fs -S would leave the file system completely empty.
+
+Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
+honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
+installed an mke2fs binary using that name.
+
+The usage and help messages for the -G, -t and -T options in mke2fs
+have been fixed.
+
+If e2fsck needs to use the backup group descriptors, the
+ext2fs_open2() function clears the UNINIT bits to ensure all of the
+inodes in the file systems get scanned. However, the code which reset
+the UNINIT flags did not also recalculate the checksum, which produced
+many spurious (and scary) e2fsck messages. This has been fixed by
+resetting cheksums when the UNINIT bits are cleared.
+
+Relax a check in e2fsck which required that the block bitmap to be
+initialized when the inode bitmap is in use. This will allow us to
+eventually eliminate code from the kernel which forcibly initialized
+the block bitmap when the inode bitmap is first used, requiring an
+extra journal credit and disk write. (Addresses Google Bug: #5944440)
+
+Make sure rdebugfs (which may be installed setuid or setgid disk) does
+not honor environment variables if euid != uid or egid != gid.
+
+Debugfs's ncheck command has been optimized and now is much more
+robust with faced with corrupted file systems. The ncheck command
+also now has a -c option which will verify the file type information
+in the directory entry to see if matches the inode's mode bits. This
+is extremely useful when trying to use debugsfs to determine which
+parts of the file system metadata can be trusted.
+
+E2image will try to use ftruncate64() to set the i_size for raw
+images, instead of writing a single null byte. This avoid allocating
+an extra block to the raw image, for those file systems and/or
+operating systems that support this. (Linux does.) In addition, fix
+a logic bug that caused the file to not be properly extended if the
+size of the last hole was exactly an multiple of a megabyte.
+
+Fixed a bug in resize2fs where for 1k and 2k file systems, where
+s_first_data_block is non-zero, this wasn't taken into account when
+calculate the minimum file system size for use with the -M option.
+
+Fixed the badblocks program to honor the -s flag when in read-only -t
+mode. (Addresses Debian Bug #646629)
+
+Update Czech, Dutch, French, Polish, and Sweedish translation from the
+Translation Project.
+
+Fixed various Debian Packaging issues so that dpkg-buildflags is used
+if present, which allows e2fsprogs to be built with security hardening
+flags. (Addresses Debian Bugs: #654457)
+
+Programmer's Notes
+------------------
+
+Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
+This was only an issue for programs compiled against e2fsprogs 1.41
+that manipulate bitmaps directly. (Addresses Sourceforge Bugs:
+#3451486)
+
+The libext2fs library now uses sysconf() to fetch the page size, instead
+of the deprecated getpagesize().
+
+The ext2fs_get_pathname() function will return a partial path if an a
+directory in the path is not a directory, displaying it as an inode
+number in angle brackets instead of giving up and displaying an error.
+This is much more helpful when a user is trying to debug a corrupted
+file system.
+
+Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
+
+Added a new library function, ext2fs_file_get_inode_num(), for use by
+fuse2fs.
+
+Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
+file, it actually works.
+
+The block iterator now properly honors the BLOCK_ABORT flag for
+extent-based flags. Previously, it didn't, which generally made code
+be less efficient, but it could cause bugs in ext2fs_link(), for
+example, by causing it to insert multiple directory entries.
+
+Fixed an (harmless other than causing a compiler warning) use of an
+uninitialized variable in e2fsck's MMP code.
+
+
+E2fsprogs 1.42 (November 29, 2011)
+==================================
+
+This release of e2fsprogs has support for file systems > 16TB. Online
+resize requires kernel support which will hopefully be in Linux
+version 3.2. Offline support is not yet available for > 16TB file
+systems, but will be coming.
+
+This release of e2fsprogs has support for clustered allocation. This
+reduces the number of block (now cluster) bitmaps by allocating and
+deallocating space in contiguous power-of-2 collections of blocks,
+which are called clustered. This is a file system level feature,
+called 'bigalloc', which must be enabled when the file system is
+initially formatted. It is not backwards compatible with older
+kernels.
+
+Added support for the Multi-Mount Protection (MMP) feature.
+
+E2fsck more efficiently uses scratch files for really big file
+systems. (This is a feature that has to be turned on explicitly; see
+[scratch_files] in the e2fsck.conf man page.)
+
+Fix a bug in e2fsck where if the free blocks and inodes counts are
+incorrect, e2fsck would fix them without printing an error message.
+This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
+any explanation of what was fixed.
+
+E2fsck will no longer attempt to clone an extended attribute block in
+pass1b handling if the file system does not support extended
+attributes.
+
+E2fsck will be more careful accidentally asking the user to continue
+if the file system is mounted, so that an escape sequence won't cause
+a false positive. (Addresses Debian Bug: #619859)
+
+E2fsck now uses less cpu time in pass 5 when large portions of the
+bitmaps are uninitialized.
+
+E2fsck will no longer segault when a corrupted file system has a bad
+extent, and removing it leads to a block needing to be deallocated.
+(Addresses SourceForge Bug: #2971800)
+
+E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
+and print debugging information to make it easier to find potential
+problems.
+
+E2fsck will check to see if the bad block inode looks insane, and will
+skip trying to use if it certain fields which should be zero look
+non-zero. This is to avoid a corrupted bad block inode causing e2fsck
+to get confused and do more harm than good.
+
+If e2fsck modifies certain superblock fields which the kernel doesn't
+look at, it will now mark the superblock as dirty without marking the
+file system as changed. This avoids signalling the init scripts that
+a reboot is necessary, since the kernel isn't going to look at those
+fields, so it won't care if they have been changed.
+
+Fixed a bug in the libext2fs library (in the binary search routine of
+the icount abstraction) that could (very, very rarely) cause e2fsck to
+die in the middle of pass 1 or pass 2 processing.
+
+E2fsck will not try to do a discard operation if the -n option was
+specified on the command line.
+
+E2fsck now supports an extended "discard" option which will cause
+e2fsck to attempt discard all unused blocks after a full, successful
+file system check.
+
+E2fsck will check for the bad block inode to make sure it looks sane
+before trusting it, to avoid causing more harm than good to the file
+system.
+
+E2fsck now returns additional status bits in its exit code if it
+aborts early in the e2fsck run.
+
+E2fsck now correctly calculates the maximum file size in the case of
+the huge_file file system feature enabled without extents.
+
+The mke2fs and e2fsck programs now tries to use the punch hole command
+as a "discard" when operating on normal files.
+
+The e2image program now supports the qcow2 format, which is a more
+efficient way of capturing file system dumps.
+
+Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
+per-device defaults to be specified in the configuration file.
+
+Mke2fs now supports the reserved_ratio relation in the [defaults] and
+[fs_types] section in mke2fs.conf.
+
+Mke2fs now creates extent-mapped directories for the root and
+lost+found directories.
+
+Mke2fs will skip zero'ing the journal if the extended option
+"lazy_journal_init" is specified. This can save a lot of time, but it
+does add a small amount of risk if the system crashes before the
+journal is overwritten entirely once. It is epsecially useful for
+testing.
+
+Mke2fs will now create file systems that enable user namespace
+extended attributes and with time- and mount count-based file
+system checks disabled.
+
+Mke2fs will not set a stride or strip size of one block based on block
+device attributes obtained from sysfs.
+
+Mke2fs now displays a progress report during the discard process.
+
+Mke2fs now handles extreme file system parameters correctly which
+previously caused the inodes per group to drop below 8, leading to a
+segfault. (The inodes per group must be a multiple of 8, but the code
+didn't correctly deal with an inodes per group count less than 8.)
+
+Mke2fs and tune2fs previously would give an error if the user tried
+setting the stride and stripe-width parameters to zero; but this is
+necessary to disable the stride and stripe-width settings. So allow
+setting these superblock fields to zero. (Addresses Google Bug:
+#4988557)
+
+Mke2fs now gives a warning if the auto-detected block size exceeds the
+system's page size.
+
+If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
+is the default), mke2fs will now set the s_max_mnt_count superblock
+field to -1, instead of 0. Kernels older then 3.0 will print a
+spurious message on each mount then they see a s_max_mnt_count set to
+0, which will annoy users. (Addresses Debian Bug: #632637)
+
+The default mke2fs.conf now has entries for "big" and "huge", which
+are needed for very big file systems.
+
+The resize2fs program now has support for a new online resize ioctl
+that can support file systems > 16TB, once it arrives in v3.x kernels.
+
+Fixed bug which caused resize2fs to fail when shrinking an empty file
+system down to its minimal size. (Addresses Sourceforge Bug #3404051)
+
+Fixed tune2fs's mount options parsing. (Addresses Debian Bug: #641667)
+
+Allow tune2fs to remove external journals if the device can not be
+found.
+
+Debugfs's icheck will now correctly find inodes which use the
+searched-for block as an extended attribute block.
+
+Debugfs now has a new "punch" command which remove blocks from the
+middle of an inode.
+
+Debugfs now has a new "e2freefrag" command which analyzes the free
+space fragmentation of the file system, using the same code as the
+e2freefrag program.
+
+Debugfs now has a "filefrag" command which displays information about
+a file's fragmentation.
+
+Add support to build a metadata-only, read-only, stripped-down version
+of debugfs called rdebugfs.
+
+Fixed a potential stack overrun bug in debugfs.
+
+The badblocks program now correctly recovers from I/O errors when
+direct I/O is being used. The badblocks command now also supports a
+-B option which forces the use of buffered I/O, and the -v option will
+provide a more detailed breakdown of read, write, and failed
+comparison errors.
+
+Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
+
+Added support for journals larger than 2GB.
+
+Support using both hard links and symlinks when installing e2fsprogs.
+
+Add overflow checking to tune2fs -i's fsck interval, which must fit in
+a 32-bit field.
+
+The debugfs command now has a new 'blocks' command which prints out
+data blocks of a particular inode in a format which is useful for
+scripting.
+
+Filefrag will report 0 extents correctly in verbose mode. (Addresses
+RedHat Bugzilla: #653234)
+
+Filefrag has been fixed so its -v report prints the correct expected
+block number (previously there had been an off-by-one error). In
+addition, it will now display the number of contiguous extents when -v
+is not specified. This makes it consistent with the number of extents
+printed when the -v option was specified. In addition, the number of
+contiguous extents is far more interesting/useful than the number of
+physical extents for very large files. (Addresses Debian Bug:
+#631498, #644792)
+
+Logsave's usage message has been fixed. (Addresses Debian Bug:
+#619788)
+
+Avoid an infinite loop in ext2fs_find_block_device() if there are
+symlink loops in /dev caused by a buggy udev.
+
+Added a useful "fallocate" program to the contrib directory.
+
+Fixed an ABI compatibility problem in libext2fs which broke the dump
+program. Also added back some macros which dump needed so it could
+compile against the latest version of ext2_fs.h (Addresses Debian Bug:
+#636418)
+
+Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
+Debian Bug: #641667)
+
+Added internationalization support for libcom_err error table strings.
+
+Fixed various spelling mistakes found in various output strings found
+by I18N translators.
+
+Update translations: French, Chinese, Germany, Indonesian, Swedish,
+Vietnamese, Polish, Dutch, Czech. (Addresses Debian Bugs: #520985,
+#620659)
+
+Fixed various Debian Packaging issues. (Addresses Debian Bugs:
+#614662, #632169, #641838, #627535, #629355)
+
+Updated/clarified man pages. (Addresses Debian Bugs: #639411,
+#642193, #634883)
+
+Programmer's Notes
+------------------
+
+Initial support for quota as an integrated feature, where the quota
+files are hidden system files that are automatically maintained by
+e2fsck is present, although disabled by default. It must be enabled
+by using the configure option --enable-quota.
+
+Reserved the on-disk fields for the metadata checksum and snapshot
+features, which are currently in development.
+
+The ext2fs library now has the new functions ext2fs_punch(),
+ext2fs_get_memzero() and ext2fs_file_get_inode().
+
+The ext2fs library now has support for calculating the crc32c checksum
+(via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
+
+The I/O manager now supports the discard operation.
+
+Reserved file system code points for new 1st class quota feature.
+
+Shortened the compilation lines by moving the autoconf defines to
+a config.h header file.
+
+Fixed a potential free of an unitialized pointer in
+ext2fs_update_bb_inode().
+
+Fixed miscellaneous gcc -Wall and coverity warnings.
+
+Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
+
+Fixed a build failure when OMIT_COM_ERR is defined.
+
+Improved error checking and fixed memory leaks caused by error return
+paths.
+
+Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
+the fsync() to be skipped.
+
+Added a test for extent-mapped journals by mke2fs and tune2fs.
+
+Added a test for creating a large (over 4GB) journal using mke2fs.
+
+Added a test to make sure the inode size remains constant.
+
+The regression test script now prints the list of which tests failed.
+
+The regression test system now uses /tmp for its scratch files, which
+is often a tmpfs mounted file system and hence much faster.
+
+The i_e2image test was fixed so it works with valgrind.
+
+Tests that rely on debugfs are now skipped if debugfs wasn't built.
+
+Fixed the dependencies for "make check" so all required dependencies
+are built before running the gression tests.
+
+A link to com_err.h is installed in $(includedir) during a "make install".
+
+The po/*.gmo files are automatically rebuilt if they are missing or
+out of date. This helps out Debian packaging.
+
+Allow ext2fs_get_memalign() to compile on systems that don't have
+posix_memalign().
+
+Fixed a namespace leak in libext2fs (tdb_null).
+
+
+E2fsprogs 1.41.14 (December 22, 2010)
+=====================================
+
+Fix spurious complaint in mke2fs where it would complain if the file
+system type "default" is not defined in mke2fs.conf.
+
+The resize2fs program will no longer clear the resize_inode feature
+when the number reserved group descriptor blocks reaches zero. This
+allows for subsequent shrinks of the file system to work cleanly for
+flex_bg file systems.
+
+The resize2fs program now handles devices which are exactly 16T;
+previously it would give an error saying that the file system was too
+big.
+
+E2fsck (and the libext2fs library) will not use the extended rec_len
+encoding for file systems whose block size is less than 64k, for
+consistency with the kernel.
+
+Programming notes
+-----------------
+
+E2fsprogs 1.41.13 would not compile on big-endian systems. This has
+been fixed. (Addresses Sourceforge Bug: #3138115)
+
+The ext2fs_block_iterator2() function passed an incorrect ref_offset
+to its callback function in the case of sparse files. (Addresses
+Sourceforge Bug: #3081087)
+
+Fix some type-punning warnings generated by newer versions of gcc.
+
+
+E2fsprogs 1.41.13 (December 13, 2010)
+=====================================
+
+E2fsck now supports the extended option "-E journal_only", which
+causes it to only do a journal replay. This is useful for scripts
+that want to first replay the journal and then check to see if it
+contains errors.
+
+E2fsck will now support UUID= and LABEL= specifiers for the -j option
+(which specifies where to find the external journal). (Addresses
+Debian Bug #559315)
+
+E2fsck now has support for the problems/<problem code>/force_no
+configuration option in e2fsck.conf, which forces a problem to not be
+fixed.
+
+Dumpe2fs will now avoid printing large negative offsets for the bitmap
+blocks and instead print a message which is a bit more helpful for
+flex_bg file systems.
+
+Mke2fs will now check the file system type (specified with the -t
+option) to make sure it is defined in the mke2fs.conf file; if it is
+not, it will print an error and abort. If the usage type (specified
+with the -T option) is not defined in mke2fs.conf, mke2fs will print a
+warning but will continue. (Addresses Debian Bug #594609)
+
+Clarified error message from resize2fs clarifying that on-line
+shrinking is not supported at all. (Addresses Debian Bug #599786)
+
+Fix an e2fsck bug that could cause a PROGRAMMING BUG error to be
+displayed. (Addresses Debian Bug #555456)
+
+E2fsck will open the external journal in exclusive mode, to prevent
+the journal from getting truncated while it is in use due to a user
+accidentally trying to run e2fsck on a snapshotted file system volume.
+(Addresses Debian Bug #587531)
+
+Fix a bug in e2fsck so it has the correct test for the EOFBLOCKS_FL
+flag.
+
+The tune2fs program can now set the uninit_bg feature without
+requiring an fsck.
+
+The tune2fs, dumpe2fs, and debugfs programs now support the new ext4
+default mount options settings which were added in 2.6.35.
+
+The e2fsck and dumpe2fs programs now support the new ext4 superblock
+fields which track where and when the first and most recent file
+system errors occurred. These fields are displayed by dumpe2fs and
+cleared by e2fsck. These new superblock fields were added in 2.6.36.
+
+Debugfs now uses a more concicse format for listing extents in its
+stat command. This format also includes the interior extent tree
+blocks, which previously was missing from stat's output for
+extent-based files.
+
+Debugfs has a new option, -D, which will request Direct I/O access of
+the file system.
+
+Mke2fs will skip initializing the inode table if a device supports
+discard and the discard operation will result in zero'ed blocks.
+
+Badblocks will now correctly backspace over UTF-8 characters when
+displaying its progress bar. (Addresses Gentoo Bug #309909; Addresses
+Debian Bugs #583782 and #587834)
+
+E2freefrag will now display the total number of free extents.
+
+Resize2fs -P no longer requires a freshly checked filesystem before
+printing the minimum resize size.
+
+Fixed a floating point precision error in a binary tree search routine
+that can lead to seg fault in e2fsck and resize2fs.
+
+Fixed a bug in e2fsck where if both the original and backup superblock
+are invalid in some way, e2fsck will fail going back to the original
+superblock because it didn't close the backup superblock first, and
+the exclusive open prevented the file system from being reopened.
+
+Fixed a big in e2freefrag which caused getopt parsing to fail on
+architectures with unsigned chars. (Addresses Gentoo Bug: #299386)
+
+Clarified an mke2fs error message so a missed common in an -E option
+(i.e., mke2fs -t ext4 -E stride=128 stripe-width=512 /dev/sda1")
+results in a more understandable explanation to the user.
+
+Mke2fs now displays the correct valid inode ratio range when
+complaining about an invalid inode ratio specified by the user.
+
+Mke2fs now understands the extended option "discard" and "nodiscard",
+and the older option -K is deprecated. The default of whether
+discards are enabled by default can be controled by the mke2fs.conf
+file.
+
+Mke2fs's handling of logical and physical sector sizes has been
+improved to reflect the fact that there will be some SSD's with 8k and
+16k physical sectors arriving soon. Mke2fs will no longer force block
+size to be the physical sector size, since there will be devices where
+the physical sector size is larger than the system's page size, and
+hence larger than the maximal supported block size. In addition, if
+the minimal and optimal io size are not exported by the device, and
+the physical sector size is larger than the block size, the physical
+sector size will be used to set the Raid I/O optimization hints in the
+superblock.
+
+E2fsck will now display a better, more specific error message when the
+user enters a typo'ed device name, instead of blathering on about
+alternate superblocks.
+
+Fixed various Debian Packaging Issues
+
+Updated/clarified man pages (Addresses Debian Bugs: #580236, #594004,
+#589345, #591083; Addresses Launchpad Bug: #505719)
+
+Update the Chinese, Chzech, Dutch, French, Germany, Indonesian,
+Polish, Swedish, and Vietnamese translations.
+
+
+Programmer's Notes
+------------------
+
+Fix a dependency definition for the static and profiled blkid
+libraries which could cause compile failures in some configurations.
+(Addresses Debian Bug: #604629)
+
+Add support for Direct I/O in the Unix I/O access layer.
+
+Fixed a memory leak in the Unix I/O layer when changing block sizes.
+
+Fixed minor memory leaks in mke2fs.
+
+Added a new function to the ext2fs library, ext2fs_get_memalign().
+
+The tst_super_size test program will check to make sure the superblock
+fields are correctly aligned and will print them out so they can be
+manually checked for correctness.
+
+Fixed some makefile dependencies for test programs in lib/ext2fs.
+
+Reserved the feature flags and superblock fields needed for the Next3
+snapshot feature.
+
+Reserved the feature flags for EXT4_FEATURE_INCOMPAT_DIRDATA and
+EXT4_INCOMPAT_EA_INODE.
+
+
+E2fsprogs 1.41.12 (May 17, 2010)
+================================
+
+Mke2fs now gives a correct error message if the external journal
+device is not found. (Addresses Red Hat Bug #572935)
+
+Resize2fs -P will now refuse to print a minimum size if the file
+system is not clean. Previously it would go ahead and print a minimum
+size anyway, which might not be correct, leading to user confusion.
+
+E2fsck now tests for extents that begin at physical block 0 and
+rejects them as invalid. (Addresses Google Bug: #2573806)
+
+Fixed a bug in e2fsck which could cause it to crash when trying to
+remove an invalid extent and the block bitmaps hadn't yet been loaded.
+(Addresses SourceForge Bug: #2971800)
+
+E2fsck now will completely skip time-based checks if the system clock
+looks insane or the option broken_system_clock is set in
+/etc/e2fsck.conf.
+
+E2fsck would previously report an i_blocks corruption for a 4T file
+created using posix_fallocate; this bug has been fixed.
+
+E2fsck will now correctly mark a sparse journal as invalid and will
+delete and recreate the journal to address the problem.
+
+E2fsck would previously incorrectly ask the user whether she would
+like to abort the file system check after finding a problem --- and
+then abort regardless of the user's answer. This is annoying, and
+has been fixed.
+
+E2fsck can now continue even if it fails to recreate the resize
+inode; previously it would just abort the file system check
+altogether.
+
+E2fsck could potentially remove directory entries for inodes found in
+the unused region of the inode table; this would generally happen on
+ext4 file systems that do not use journaling. This bug has been fixed
+by not clearing these directory entries once it has been established
+that bg_unused_inodes may not be trustworthy; once pass #2 has been
+completed, e2fsck will restart the file system check from the
+beginning, and then it will be safe to delete any directory entries
+pointing to inodes that appear to be deleted. (Addresses Google Bug:
+#2642165)
+
+E2fsck will not try to set the block group checksums if the user
+cancels the fsck with a control-C. It's a bad idea to set the
+checksums if e2fsck hasn't been completed, and it often results an the
+error message, "Inode bitmap not loaded while setting block group
+checksum info". (Addresses Launchpad Bug: #582035)
+
+The mke2fs program now queries the kernel for the physical as well as
+the logical sector size, and will not allow a blocksize below the
+logical, and will strongly encourage a blocksize at least as big as
+the physical blocksize. This is needed for 4k sector drives that
+emulate 512 byte sector sizes.
+
+Mke2fs will now allow a flex_bg size of 1. This is unusual, and
+rarely needed, but it is a legal value.
+
+E2fsck will check for cases where the EOFBLOCKS_FL is set when it is
+not needed, and offer to clear it; this is a sign of a kernel bug, but
+more importantly, some released kernels may crash when this situation
+is encountered on ext4 file systems. (Addresses Google Bug: #2604224)
+
+E2fsck will use the EOFBLOCKS_FL flag exclusively to check whether
+i_size is correct. (Kernels starting with 2.6.34 will set
+EOFBLOCKS_FL.)
+
+The com_err library will now only output ^M (a CR character) when the
+tty is in raw mode.
+
+Update the Czech, Chinese, Dutch, French, Germany, Indonesian, Polish,
+and Vietnamese translations.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #571247, #563487)
+
+
+Programmer's Notes
+------------------
+
+The regression test suite now uses its own mke2fs.conf file, so that
+downstream distributions want change the mke2fs.conf file which is
+distributed in the RPM or dpkg file, without worrying about screwing
+up the regression test results.
+
+Always build namei.o so that building with configure --disable-debugfs
+works correctly. Long-term, if we care about reduced e2fsprogs
+builds, we need a more general solution for deciding what .o files are
+needed for a particular build. Given that install floppies are going
+(gone?) the way the dodo bird, we probably don't care, though.
+(Addresses Sourceforge Bug: #2911433)
+
+Add configure options --enable-symlink-build and
+--enable-symlink-install, which allow e2fsprogs be built using
+symlinks instad of hard links, and to be installed using symlinks
+instead of hard links, respectively. It is useful when the file
+system where the build is taking place, or the file system where
+e2fsprogs is installed, can't handle hard links for some reason.
+(Addresses Sourceforge Bug: #1436294)
+
+Fixed compile warning in mke2fs.c.
+
+
+E2fsprogs 1.41.11 (March 14, 2010)
+==================================
+
+E2fsck will no longer give a fatal error and abort if the physical
+device has been resized beyond 2**32 blocks. (Addresses Launchpad
+Bug: #521648)
+
+Debugfs has a bug fixed so that "logdump -b <blk>" now properly shows
+the allocation status of the block <blk>. (Addresses Debian Bug:
+#564084)
+
+E2fsck now prints a much more emphatic and hopefully scary message
+when a file system is detected as mounted while doing a read/write
+check of the filesystem. Hopefully this will dissuade users from
+thinking, "surely that message doesn't apply to *me*" :-(
+
+E2fsck -n will now always open the file system read-only. We now
+disallow certain combination of options which previously were manual
+exceptions; this is bad because it causes users to think they are
+smarter than they really are. So "-n -c", "-n -l", "-n -L", and "-n
+-D" are no longer supported. (Addresses Launchpad Bug: #537483)
+
+In e2fsprogs 1.41.10, mke2fs would ask for confirmation to proceed if
+it detected a badly aligned partition. Unfortunately, this broke some
+distribution installation scripts, so it now just prints the warning
+message and proceeds. (Addresses Red Hat Bug: #569021. Addresses
+Launchpad Bug: #530071)
+
+Mke2fs would take a long time to create very large journal files for
+ext4. This was caused by a bug in ext2fs_block_iterate2(), which is
+now fixed.
+
+E2fsck now understands the EOFBLOCKS_FL flag which will be used in
+2.6.34 kernels to make e2fsck not complain about blocks deliberately
+fallocated() beyond an inode's i_size.
+
+E2fsprogs 1.41.10 introduced a regression (in commit b71e018) where
+e2fsck -fD can corrupt non-indexed directories when are exists one or
+more file names which alphabetically sort before ".". This can happen
+with ext2 filesystems or for small directories (take less than a lock)
+which contain filenames that begin with a space or some other
+punctuation mark. (Addresses Debian Bug: #573923, Addresses Launchpad
+Bug: #525114)
+
+
+Programmer's Notes
+------------------
+
+Add new test, f_rehash_dir, which checks to make sure e2fsck -D works
+correctly.
+
+The libcom_err function now has support for Heimdal's com_right_r
+function(). (Addresses Sourceforge Bug: #2963865, Addresses Debian
+Bug: #558910)
+
+
+E2fsprogs 1.41.10 (February 7, 2010)
+====================================
+
+Fix resize2fs bug which causes it to access invalid memory.
+
+Add libss support for libreadline.so.6.
+
+Fix e2fsck's check for extent-mapped directory with an incorrect file
+type.
+
+Add new e2fsck.conf configuration option, default/broken_system_clock
+to support systems with broken CMOS hardware clocks. Also, since too
+many distributions seem to have broken virtualization scripts now,
+e2fsck will by default accept dates which are off by up to 24 hours by
+default. (Addresses Debian Bugs: #559776, #557636)
+
+Fix a bug where mke2fs may not use the best placement of the inode
+table when there is only room for a single block group in the last
+flex_bg.
+
+E2fsck is now smarter when it needs to allocate blocks in the course
+of fixing file system problems. This reduces the number of spurious
+differences found in pass #5.
+
+E2fsck will no longer rehash directories which fit in a single
+directory block.
+
+E2fsck now correctly handles holes in extent-mapped directories (i.e.,
+sparse directories which use extents).
+
+Fix big-endian problems with ext2fs_bmap() and ext2fs_bmap2().
+
+Fix a bug in filefrag where on platforms which can allow file systems
+with 8k blocks, that it doesn't core dump when it sees a file system
+with 8k block sizes. (Thanks to Mikulas Patocka for pointing this
+out.)
+
+E2fsck will correctly fix directories that are have an inaccurate
+i_size as well as other problems in a single pass, instead of
+requiring two e2fsck runs before the file system is fully fixed.
+
+Fix e2fsck so it will correctly find and detect duplicate directory
+entries for non-indexed directories. ( Addresses Sourceforge Bug:
+#2862551)
+
+Mke2fs will use BLKDISCARD to pre-discard all blocks on an SSD or
+thinly-provisioned storage device. This can be disabled using the -K
+option.
+
+Enhance libext2fs so it works around bug in Linux version 2.6.19
+and earlier where the /proc/swaps file was missing the header on
+the first line.
+
+Fix bug in Linux version 2.6.19 and earlier where the /proc/swaps file
+was missing the header on the first line.
+
+Fix some big-endian bugs in e2fsck and libext2fs.
+
+Fix resize2fs so it works correctly on file systems with external
+journals instead of failing early with the error "Illegal inode
+number".
+
+Fix libss so that it does not seg fault when using a readline library
+which does not supply a readline_shutdown() function.
+
+Updated dumpe2fs's usage message so it correctly gives the right
+arguments summary for "-o superblock=<num>" and "-o blocksize=<num>".
+(Addresses Launchpad Bug: #448099)
+
+Teach libext2fs to ignore the high 32 bits of the i_blocks field
+when huge_file file system feature is set, but the inode does not
+have the HUGE_FILE_FL flag set.
+
+Fix e2fsck's handling of 64-bit i_blocks fields.
+
+E2fsck will now print "Illegal indirect block", "Illegal
+double-indirect block", etc., instead of "Illegal block #-1" or
+"Illegal block #-2", etc. This makes it easier for users to
+understand what has gone wrong. (Addresses SourceForge Bug: #2871782)
+
+Mke2fs now will obtain get device topology information from blkid and
+use it to populate the superblock stride and stripe sizes. It will
+also warn if the block device is misaligned
+
+Fix file descriptor leaks in fsck and debugfs. (Addresses Novell Bug:
+##524526)
+
+Fix the libext2fs library code to round up the bitmap size to a 4-byte
+boundary, to prevent spurious seg faults caused by the x86
+architecture. This doesn't affect Linux systems, but was a major
+problem on a number of *BSD systems. (Addresses Sourceforge Bug:
+#2328708)
+
+Fix resize2fs's minimum size required for a file system so it doesn't
+fail when "resize2fs -M" is run. (Addresses RedHat Bugzilla: #519131)
+
+Dumpe2fs now prints summary information about the contents of the
+journal.
+
+Avoid printing scary error messages when e2fsck starts running
+problems on low-memory systems, as it tends to panic and mislead the
+user. (Addresses Debian Bug: #509529)
+
+Fix blkid's modules.dep parser so it handles compressed (.ko.gz)
+modules files. (Address Red Hat Bug: #518572)
+
+Fix tune2fs so it can add a journal when an extent-enabled file system
+is mounted. (Addresses Launchpad bug: #416648)
+
+Update Czech, Indonesian, Polish and Vietnamese translations (from the
+Translation Project).
+
+Update/clarify man pages. (Addresses Sourceforge Bug: #2822186)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #540111)
+
+Programmer's Notes
+------------------
+
+The configure script supports the --with-cc, --with-ccopts, and
+--with-ldopts options. Instead, the more standard use of CC=,
+CCFLAGS=, and LDFLAGS= in the configure command line is used instead.
+Also, --with-ld, which never worked, was also removed.
+(Addresses Sourceforge Bug: #2843248)
+
+The in-tree header files are only used if the in-tree uuid or blkid
+libraries are used. Otherwise, use the system-provided uuid or blkid
+header files if using the system-provided libraries.
+
+Fix some build failures caused by --disable-* configure options.
+
+Work around a bug in autoconf 2.64.
+
+
+E2fsprogs 1.41.9 (August 22, 2009)
+==================================
+
+Fix a bug in e2fsck routines for reallocating an inode table which
+could cause it to loop forever on an ext4 filesystem with the FLEX_BG
+filesystem feature with a relatively rare (and specific) filesystem
+corruption. This fix causes e2fsck to try to find space for a new
+portion of the inode table in the containing flex_bg, and if that
+fails, the new portion of the inode table will be allocated in any
+free space available in the filesystem.
+
+Make e2fsck less annoying by only asking for permission to relocate a
+block group's inode table once, instead of for every overlapping
+block. Similarly, only ask once to recompute the block group
+checksums, instead of once for each corrupted block group's checksum.
+
+Fix filefrag to avoid print the extent header if the FIEMAP ioctl is
+not present, and it needs to fall back to using the FIBMAP ioctl.
+
+Fix filefrag to correctly print the number of extents for zero-length
+files. (Addresses Debian Bug: #540376)
+
+Filefrag now has a -B option which forces the use of the FIBMAP ioctl
+to more easily debug the FIBMAP code.
+
+Fixed filefrag for non-extent based files.
+
+Add a new program, e2freefrag, which displays information about the
+free space fragmentation in an ext2/3/4 filesystem.
+
+Fix inode resizing via tune2fs -I so that it works correctly in the
+face of non-empty bad blocks inodes, and if the filesystem was
+formatted using the "mke2fs -E stride=N" option for RAID arrays.
+
+Fix regression in ext2fs_extent_set_bmap() caused e2fsck -fD to fail
+and corrupt large directories if the directory needs to shrink by more
+than one block. (Addresses Debian Bug: #537510)
+
+Fix e2fsck's buggy_init_scritps=1 so that the if the last write and/or
+last mount times are in the future, they are corrected even if
+buggy_init_scripts is set. This is needed because otherwise resize2fs
+will refuse to resize the filesystem, even after running "e2fsck -f".
+(Addresses Launchpad bug: #373409)
+
+E2fsck will now print much fuller information when the last mount time
+or last written time is in the future, since most people can't seem to
+believe their distribution has buggy init scripts, or they have a
+failed CMOS/RTS clock battery.
+
+Enhance dumpe2fs to dump the extent information via the 'stat'
+command, and more detailed extent information via the new command
+'dump_extents'.
+
+Update French, Polish, Czech, and Sweedish translation from the
+Translation Project.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Programmer's Notes
+------------------
+
+Fixed miscellaneous gcc -Wall warnings.
+
+Fixed memory leak in error path in ext2fs_block_iterate2()
+
+Fixed non-Linux build of the intl directory by adding support for the
+E/Q/V macros.
+
+The bitmap read/write functions now treat uninitialized bitmaps as
+unallocated; this fixes a number of problems in all e2fsprogs for ext4
+filesystems when there is a need to allocate new blocks or inodes, and
+there aren't any free blocks or inodes in the already-used block
+groups.
+
+Improve ext2fs_extent_set_bmap() to avoid creating new extents which
+get inserted into the extent tree when they are not needed.
+
+
+E2fsprogs 1.41.8 (July 11, 2009)
+================================
+
+Fix resize2fs's online resizing, fixing a regression which in
+e2fpsrogs 1.41.7. (Addresses Debian Bug: #535452)
+
+Fix potential filesystem corruptions caused by using resize2fs to
+shrinking ext4 filesystems with extents enabled. (Addresses Red Hat
+Bug: #510379)
+
+Optimize uuid_generate() to avoid running uuidd if it is not setuid or
+setgid and the currently running program doesn't have write access to
+the uuidd work directory.
+
+Add safety checks (for non-Linux systems) so that uuidd isn't run with
+file descriptors 0, 1, and 2 closed; and if they are closed, uuidd
+will be careful not to close the file descriptor for its unix domain
+socket when it detaches itself from the controlling tty. Also add
+safety checks so that if the unix domain socket between the uuid
+library and uuidd program is closed for any reason, both the library
+and the uuidd will return an appropriate error code instead of looping
+in an infinite loop.
+
+The e2croncheck script, which creates an LVM snapshot and then checks
+the ext3/4 filesystem via the LVM snapshot, has been added to the
+contrib directory.
+
+Fix filefrag program for files that have more than 144 extents.
+
+Update French, Polish, Czech, Indonsian, and Sweedish translation from
+the Translation Project.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug #535530)
+
+Update/clarify man pages.
+
+Programmer's Notes
+------------------
+
+Fix compilation problem when configured with --disable-uuid.
+
+Don't build uuidgen if configured with --disable-uuid.
+
+Add the new library function ext2fs_test_inode_bitmap_range(), and
+optimized ext2fs_test_block_bitmap_range(), which will be needed for
+future optimizations for e2fsck.
+
+Fix makefile dependencies for libcom_err so that the Makefiles work
+well on non-GNU make program. (Addresses Sourceforge Patches: #2813809)
+
+Enhance the build system so that the full set of commands executed by
+the Makefiles are displayed, instead of the Linux kernel summary
+output, if the build was configured with --enable-verbose-makecmds, or
+if GNU make is in use and the V variable is non-null, i.e., via "make
+V=1".
+
+
+E2fsprogs 1.41.7 (June 29, 2009)
+================================
+
+Fix a bug in libext2fs which can cause e2fsck and resize2fs to write
+uninitalized data into the portion of the inode beyond the first 128
+bytes when operating on inodes mapped via extents; potentially
+corrupting filesystems.
+
+Fix memory leaks in e2fsprogs, including a very large memory leak
+which can cause e2fsck to run out of memory when checking very large
+filesystems using extents.
+
+The logsave program will now filter out the ^A and ^B characters when
+writing to the console.
+
+Harden ext2fs_validate_entry() so that lsdel will not read beyond the
+end of the block even if the directory block is corrupted.
+
+Fix debugfs from core dumping if the logdump command fails to open the
+output file.
+
+Enhance badblocks to print the currently tested block number when
+interrupted with ^C.
+
+Fix lsattr to exit with a non-zero status when it encounters errors.
+(Addresses RedHat Bugzilla #489841)
+
+Fix e2fsprogs to use the same encoding for rec_len in 64k (and larger)
+filesystems as the kernel when encoding rec_len >= 64k. For 64k
+filesystems (currently all that is supported by e2fsprogs, this is
+only a minor corner case).
+
+Resize2fs will now update the journal backup fileds in the sup0erblock
+if the journal is moved; this avoids an unnecessary full fsck after
+resizing the filesystem. (Addresses RedHat Bugzilla: #505339)
+
+Fix libext2fs to properly initialize i_extra_size when creating the
+journal and resize inodes.
+
+Change badblocks to allow block sizes larger than 4k.
+
+Fix filefrag progam so it correctly checks for errors from the fiemap ioctl.
+
+Update Chinese and Czech translation from the Translation Project.
+
+Clean up various man pages. (Addresses Debian Bug #531385 and #523063)
+
+
+Programmer's Notes
+------------------
+
+Add --disable-libuuid option to configure which uses an in-system
+installed version of libuuid; the private version is enabled by
+default.
+
+Add --valgrind-leakcheck option to the test_script program which runs
+valgrind with the appropriate options to find memory leaks.
+
+
+E2fsprogs 1.41.6 (May 30, 2009)
+===============================
+
+Fix a critical regression in e2fsck introduced version 1.41.5 which
+can undo updates to the block group descriptors after a journal replay.
+
+If e2fsck receives an I/O error while replaying the journal, prompt
+the user whether they want to ignore the error or not; if e2fsck is
+run in preen mode, force fsck to abort the preen pass.
+
+Fix a bug which would cause e2fsck to core dump if the filesystem
+contains a corrupt extent header, and the user declines to clear the
+inode. (Addresses Sourceforge Bug: #2791794)
+
+Fix e2fsck to restart only once in the case of multiple block groups
+which inodes in use that are in the uninitialized part of the block
+group's inode table.
+
+To reduce user confusion, if the /etc/mtab file is missing
+ext2fs_check_mount_point and ext2fs_check_if_mounted will return a
+new, explicit error code to indicate this case. This will cause
+e2fsck to give a clearer error message when the user is using buggy
+rescue CD's that don't properly set up /etc/mtab. (Addresses Debian
+Bug: #527859)
+
+Fix e2fsck so that if the primary group descriptors are corrupted, but
+the backup superblock is entirely invalid, to go back to using (and
+fixing) the priary group descriptors instead of completely giving up
+on the filesystem. (Addresses Debian Bug: #516820)
+
+Change e2fsck to not abort a preen pass if an inode is found to have
+i_file_acl_hi non-zero. Ext3 filesystems don't care, and newer
+kernels (post 2.6.29) will ignore this field. So let's fix it
+automatically during the preen pass instead of forcing the user to fix
+this up manually. (Addresses Debian Bug: #526524)
+
+Add resource tracking for e2fsck passes 1b through 1d.
+
+Speed up e2fsck by eliminating unnecessary journal checks if the
+filesystem is already mounted and doesn't need recovery (since the
+kernel would have run the journal when the filesystem was mounted.)
+Also speed up e2fsck by avoiding unnecessary block group descriptor
+updates in ext2fs_close().
+
+Add support to chattr to migrate inodes from using direct/indirect
+blocks to extents.
+
+Avoid corrupting the filesystem if there is an attempt to shrink a
+filesystem using resize2fs smaller than posible by making
+ext2fs_set_bmap() more careful not to delete the old block until the
+new block can be inserted. In addition, fix a bug in how the minimum
+size of the filesystem (plus a safety margin) is calculated, and
+modify resize2fs to refuse to shrink the filesystem below that minimum
+size without the force flag.
+
+Teach blkid to try to figure out DM device names using take advantage
+of information in sysfs when running on kernels (2.6.29 and later)
+which provide this information in /sys/block/dm-<N>/dm/name; this is
+much faster than scanning for the devncie number in /dev/mapper.
+
+Fix blkid to prefer /dev/mapper/<name> device names instad of the
+private /dev/dm-X names.
+
+Add an -a option to debugfs's close_filesys command which writes any
+changes to the superblock or block group descriptors to all of the
+backup superblock locations.
+
+Add support to the filefrag program to use the FIEMAP ioctl.
+
+Update Chinese translation from the Translation Project.
+
+Clean up various man pages. (Addresses Red Hat Bugzilla: #502971 and
+Launchpad Bug: #381854)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug #506064)
+
+
+Programmer's Notes
+------------------
+
+Add test code to make sure e2fsck's problem.c doesn't have two problem
+codes assigned to duplicate values.
+
+Avoid using a hard-coded path for /bin/rm in block's test_probe.in.
+(Addresses Sourceforge Bug: #2780205)
+
+Clean up e2fsck by removing #ifdef RESOURCE_TRACK by adding an empty
+function declaration for init_resource_track() and
+print_resource_track() when RESOURCE_TRACK is not defined.
+
+The test code which is used to build the tst_csum progam has been
+moved from from tst_csum.c into csum.c under an #ifdef DEBUG to to
+avoid compile problems caused by not having a prototype for
+ext2fs_group_desc_csum(). (Addresses Sourceforge Bug #2484331)
+
+Update the config.guess and config.sub file to the latest from the
+FSF, to allow e2fsprogs to build on the avr32 platform. (Addresses
+Debian Bug: #528330)
+
+Add a new function, ext2fs_extent_open2(), which behaves like
+pext2fs_extent_open(), but uses the user-supplied inode structure
+when opening an extent instead of reading the inode from disk.
+
+
+E2fsprogs 1.41.5 (April 23, 2009)
+=================================
+
+Fix a number of filesystem corruption bugs in resize2fs when growing
+or shrinking ext4 filesystems off-line (i.e., when the ext4 filesystem
+is not mounted).
+
+Debugfs can now set i_file_acl_high via the set_inodes_field command,
+and print a 64-bit file acl. This is useful for debugging filesystem
+corruptions where the high bits of i_file_acl_high are set. E2fsck
+will detect and fix non-zero i_file_acl_high on 32-bit filesystems
+since some Linux kernel versions pay attention to this field even when
+they shouldn't.
+
+Speed up e2fsck when checking clean filesystems by avoiding
+unnecessary block reads, and coalescing the block group descriptor
+blocks so they are read using a single read operation.
+
+The libuuid library will now close all file descriptors before running
+uuidd. This avoids problems when the calling program has open sockets
+which then never get closed because uuidd is a long-running helper
+daeomn. (Addresses Launchpad bug: #305057)
+
+In order to avoid unnecessary full filesystem checks by e2fsck after
+an on-line resize, e2fsck will ignore the NEEDS_RECOVERY flag set on
+the backup superblocks. (Addresses Red Hat Bugzilla: #471925)
+
+Mke2fs will avoid trying to create the journal when run in
+superblock-only mode (mke2fs -S), since the left-over journal in the
+inode table will cause mke2fs to fail.
+
+Fix a bug in libext2fs functions that check to see if a particular
+device or filesystem image is mounted, which would cause these
+functions to report that a file identical to the (relative) pathname
+used by a pseudo-filesystem was mounted when in fact it was not.
+
+Update Czech translation from the Translation Project.
+
+Add Chinese (simplified) translation from the Translation Project.
+
+Fix support for external journals (which was broken in e2fsprogs
+1.41.4).
+
+Fix a regression in debugfs where the "stat" command when no
+filesystem was open would cause debugfs to crash with a segmentation
+violation.
+
+Starting in the 2.6.29 linux kernel, the ext4 filesystem driver can be
+used to support filesystems without a journal. Update the blkid
+library so it understands this.
+
+The blkid library will remove an entry from the blkid cache
+representing the entire disk if partitions are found, since presuambly
+the device previously had no partition table, but has now transitioned
+to using a partition table.
+
+Add a check to mke2fs and tune2fs that the argument to the -m option
+(which specifies the reserved ratio) must be greater than zero.
+(Addresses Debian Bug: #517015)
+
+Add support for tracking the number kilobytes written to the
+filesystem via the superblock field s_kbytes_written. It will be
+updated by the kernel as well as by e2fsprogs programs which write to
+the filesystem. This is useful for tracking the wear to filesystems
+on Solid Sstate Drives.
+
+Fix compatibility issue in the libext2fs info file and makeinfo
+version 4.12. (Addresses Red Hat Bugzilla: #481620)
+
+Update/clarify man pages. (Addresses Debian Bug: #515693, #365619)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug: #506279)
+
+Programmer's Notes
+------------------
+
+Fix Hurd compilation problem in e2fsck and tune2fs (Addresses Debian
+Bug: #521602)
+
+Fix various gcc compilation warnings and other programming cleanups.
+(Addresses Red Hat Bugzilla: #486997)
+
+Add support for building the blkid command statically.
+
+Add support for disabling the built-in blkid library in favor of a
+system-installed blkid implementation via the configure option
+--disable-libblkid.
+
+
+E2fsprogs 1.41.4 (January 27, 2009)
+===================================
+
+Fixed a bug which could sometimes cause blkid to return an exit value
+of zero for a non-existent device (Addresses Debian Bug: #502541)
+
+Blkid will now recognize ext3 filesystems that have the test_fs flag
+set as ext3 filesystems.
+
+The blkid library will now recognize btrfs filesystems and swap
+devices currently used by user-level software suspend.
+
+Tune2fs now updates the block group checksums when changing the UUID
+to avoid causing e2fsck to complain vociferously at the next reboot.
+
+Tune2fs's inode size resizing algorithms have been fixed so it is not
+vastly inefficient for moderate-to-large filesystems, due to some
+O(n**2) and O(n*m) algorithms that didn't scale well at all.
+
+Fix tune2fs's inode resizing algorithm so it will not corrupt
+filesystems laid out for RAID filesystems; in addition, tune2fs will
+refuse to change the inode size for filesystems that have the flex_bg
+feature enabled. (This is a limitation in the current implementation
+of tune2fs -I.)
+
+E2fsprogs 1.41 broke debugfs's logdump command for normal ext3/4
+filesystems with 32-bit block numbers, when the headers for 64-bit
+block numbers was added. This regression has been fixed.
+
+Debugfs's ncheck command has been fixed to avoid printing garbage
+characters at the end of file names.
+
+Fix resize2fs for ext4 filesystems. Some blocks that that need moving
+when shrinking filesystems with uninit_bg feature would not be moved.
+In addition, blocks and inode table blocks were not being correctly
+freed when shrinking filesystems with the flex_bg feable, which caused
+resize2fs -M to fail. Finally, when blocks are moved, make sure the
+uninitialized flag in extents is preserved.
+
+Fix bug which caused dumpe2fs to abort with an error if run on a
+filesystem that contained an external journal.
+
+Some distributions used "mke3fs" as an alias for "mkfs.ext3"; check
+for this in argv[0] to provide better legacy support for these
+distributions. This is a practice that should NOT be continued,
+however.
+
+Mke2fs now has a new option -U, which allows the user to specify the
+UUID that should be used for the new filesystem.
+
+Mke2fs will treat devices that are exactly 16TB as if they were 16TB
+minus one block. This allows users who have read that ext3 supports
+up to 16TB filesystems and who create a 16TB LVM to not get confused,
+since the true limit is really 16TB minus one block.
+
+E2fsck will no longer abort an fsck run if block group has an errant
+INODE_UNINIT flag.
+
+E2fsck now distinguishes between fragmented directories and fragmented
+files in verbose mode statistics and in the fragcheck report.
+
+Fix a bug in e2fsck which casued it double count non-contiguous
+extent-based inodes.
+
+E2fsck will leave some slack space when repacking directories to allow
+room for a few directory entries to be added without causing leaf
+nodes to be split right away.
+
+Fix a bug which caused e2fsck to crash when it comes across a
+corrupted interior node in an extent tree with the error message:
+"Error1: Corrupt extent header on inode XXXXXX"
+
+E2fsck problem descriptions involving the journal are no longer
+referred to as "ext3" problems, since ext4 filesystems also have
+journals.
+
+Fix a long-standing bug in e2fsck which would cause it to crash when
+replying journals for filesystems with block sizes greater than 8k.
+
+Update Catalan translation from the Translation Project.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #503057, #502323, #511207)
+
+Programmer's Notes
+------------------
+
+Fix build of e2fsck.profiled, and add support for building profiled
+binaries in the misc directory if configured with --enable-profile.
+
+The ext2fs_open() function now performs more sanity checks on the
+superblock to avoid potential divide by zero errors by other parts of
+library.
+
+The ext2fs_read_inode_full() function now has a safety check to avoid
+a segmentation fault on corrupted filesystems.
+
+The ext2fs_new_inode() function now has a sanity check so that if the
+s_first_inode field in the superblock is insane, it will return
+EXT2_ET_INODE_ALLOC_FAIL instead of returning an invalid inode number.
+
+To avoid segmentation faults, ext2fs_block_alloc_stats() and
+ext2fs_inode_alloc_stats() now validates the passed inode or block
+number to avoid overrunning an array boundary.
+
+Various signed/unsigned errors for variables containing block numbers
+have been fixed.
+
+Accomodations for gcc's stupidity in not realizing that constant
+strings that do not contain a '%' character are safe to use in format
+strings have been made so that distributions that want to compile
+e2fsprogs with -Werror=format-security have an easier time doing so.
+
+Added a new 64-bit getsize interface, ext2fs_get_device_size2().
+
+Added the utility make-sparse.c to the contrib directory.
+
+The ext2fs_block_iterate2() function now reflects errors from
+ext2fs_extent_set_bmap() to the caller, if the callback tries to
+change a block on an extent-based file, and ext2fs_extent_set_bmap()
+fails for some reason (for example, there isn't enough disk space to
+split a node and expand the extent tree.
+
+The ext2fs_block_iterate2() function will preserve the uninit flag in
+extents when the callback function modifies a block in an extent-based
+file.
+
+E2fsck will now flag filesystems that have an insane s_first_ino field
+in their superblock, and attempt to use a backup superblock to repair
+the filesystem.
+
+
+E2fsprogs 1.41.3 (October 12, 2008)
+===================================
+
+E2fsck has been fixed so it prints the correct inode number for
+uinit_bg related problems.
+
+E2fsck will now offer to clear the test_fs flag if the ext4 filesystem
+is available on linux. This can be disabled via a configuration
+option in /etc/e2fsck.conf.
+
+Fix a file descriptor leak in libblkid when checking to see if an ext4
+or ext4dev module exists.
+
+Fix a bug in e2fsck where in preen mode, if there are disk I/O errors
+while trying to close a filesystem can lead to infinite loops.
+(Addresses Red Hat Bugzilla #465679)
+
+Fix a bug in resize2fs where passing in a bogus new size of 0 blocks
+will cause resize2fs to drop into an infinite loop. (Addresses Red
+Hat Bugzilla: #465984)
+
+Add a check in the Unix I/O functions in libext2fs so that when a
+device is opened read/write, return an error if the device is
+read-only using the BLKROGET ioctl.
+
+Fix debugfs's ncheck command so that it prints all of the names of
+hardlinks in the same directory.
+
+Fix a bug in libblkid so it correctly detects whether the ext4 and
+ext4dev filesystems are available, so that the ext4dev->ext4
+fallback code works correctly.
+
+Programmer's Notes
+------------------
+
+Fix a parallel build problem by making sure util/subst is built before
+trying to build the lib/et directory. (Addresses Sourceforge Bug:
+#2143281)
+
+Updated "make depend" information for crc16.o
+
+
+E2fsprogs 1.41.2 (October 2, 2008)
+==================================
+
+Fix e2fsck's automatic blocksize detection. This fixes a regression
+from e2fsprogs 1.40.7 which caused e2fsck to fail if the user
+specifies a block number using the -b option if the blocksize option
+isn't also specified using -B. Unfortunately, users very commonly
+invoke e2fsck using "e2fsck -b 32768 /dev/hdXXX" to use the backup
+superblock; in fack e2fsck will often suggest this kind of command
+line. Oops.
+
+Enhance the debugfs's "ncheck" command so it will print all of the
+pathnames for the specified inodes. (Previously, in some cases ncheck
+might not print a pathname for an inode at all if some of the other
+inodes had multiple hard links.)
+
+Enhance debugfs's "hash" command so the hash seed can be specified via
+a command-line option. In addition, allow the hash algorithm to be
+specified by name instead of just by number.
+
+Fix e2fsck so that we don't accidentally print the translation file's
+header when asking the user a custom question so there is no prompt
+defined for a particular problem record. For example, the question
+"Run journal anyway" will get the PO header tacked on because e2fsck
+erroneously passed the null string to _(). (Addresses Launchpad Bug:
+#246892)
+
+Enhance badblocks so that it can test a normal file which is greater
+than 2GB.
+
+Enhance the badblocks command so that it displays the time and
+percentage complete when in verbose mode. (Addresses Debian Bug:
+#429739)
+
+Fix a potential memory leak in a error handling path in debugfs's
+ncheck function.
+
+Fix a potential memory corruption problem if a memory allocation fails
+in resize2fs.
+
+Fix the usage message for debugfs's logdump command to be consistent
+with its man manpage.
+
+Update Polish, French, Vietnamese, Dutch, Indonesian, German, Czech,
+and Sweedish translation from the Translation Project.
+
+Add documentation for the file I/O functions to the libext2fs.texinfo
+file. (Addresses Debian Bug: #484877)
+
+Update and clarified various man pages. (Addresses Launchpad Bug
+#275272; Addresses Debian Bugs: #498100, #498101, #498102, #498103)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug: #497619)
+
+Programmer's Notes
+------------------
+
+Fix a potential file descriptor leack in libcom_err by setting the
+close-on-exec flag for a fd used for debugging. (Addresses Red Hat
+Bugzilla #464689)
+
+Fix a potential race in libcom_err by using sem_post/sem_init. SuSE
+has been carrying a patch for a long time to prevent a largely
+theoretical race condition if a multi-threaded application adds and
+removes error tables in multiple threads. Unfortunately SuSE's
+approach breaks compatibility by forcing applications to link and
+compile with the -pthread option; using pthread mutexes has
+historically been problematic. We fix this by using sem_post/sem_init
+instead.
+
+Fix e2fsprogs-libs build failure due to 'subs' target. (Addresses
+Sourceforge Bug: #2087502)
+
+Avoid linking e2initrd_helper, debugfs, blkid, and fsck with unneeded
+libraries when using ELF shared libraries.
+
+Fix ELF shared library when building on systems that don't already
+have the e2fsprogs shared libraries already installed. (Addresses
+Sourceforge Bug: #2088537)
+
+Fix the pkg-config files so they work correctly when linking with
+static libraries and fix the include directory so programs don't have
+to use #include <ext2fs/ext2fs.h>, but can use #include <ext2fs.h>
+instead. (Addresses Sourceforge Bug: #2089537)
+
+Make sure ext2fs_swab64() is compiled for all platforms, and not just
+for x86. (Addresses Debian Bug: #497515)
+
+Remove the unused ext2fs_find_{first,ext}_bit_set() functions for all
+non-x86 platforms. (They had been removed for x86 earlier.)
+
+Fix diet libc compilation support, which had bitrotted due to lack of
+TLC. Fixing this improves general portability.
+
+When installing the link library when using ELF shared libraries,
+avoid using absolute pathnames if the link library and the shared
+library are installed in the same directory. (Addresses Sourceforge
+Bug: #1782913)
+
+Fix gen-tarball so it will work even if the top-level directory has
+been renamed to something other than "e2fsprogs". Also make
+gen-tarball print the size of the resulting tar.gz file.
+
+
+E2fsprogs 1.41.1 (September 1, 2008)
+====================================
+
+Many people are forgetting to update their mke2fs.conf file, and this
+causes ext3, ext4, and ext4dev filesystems won't get created with the
+proper features enabled. We address this in two ways. First, mke2fs
+will issue a warning if there is not definition for an ext3, ext4, or
+ext4dev filesystem and the user is trying to create such a filesystem
+type. Secondly, when installing from a source build, "make install"
+will provide basic configuration file handling for /etc/mke2fs.conf.
+If it exists, and does not mention ext4dev, it will be moved aside to
+/etc/mke2fs.conf.e2fpsrogs-old and the new /etc/mke2fs.conf file will
+be installed. If the existing /etc/mke2fs.conf file does mention
+ext4dev, then "make install" will install official mke2fs.conf file as
+/etc/mke2fs.conf.e2fsprogs-new and issue a message to the user that
+they should look to see if any changes need to be merged.
+
+The mke2fs program will now create the journal in the middle of the
+filesystem, since this minimizes seek times on average for fsync-heavy
+workloads. In addition, mke2fs will now create journals using extents
+for filesystems that support them. This results in a more efficient
+encoding for the journal since it eliminates the need for using
+indirect blocks.
+
+The mke2fs program will avoid allocating an extra block to the
+journal. (Addresses Sourceforge Bug: #1483791)
+
+Mke2fs will correctly enforce the prohibition against features
+(specifically read-only features) in revision 0 filesystems. (Thanks
+to Benno Schulenberg for noticing this problem.)
+
+Mke2fs previously would occasionaly create some slightly non-optimally
+placed inode tables; this bug has been fixed.
+
+The mke2fs and tune2fs programs now print the correct usage message
+describing the maximum journal size. (Addresses Debian Bug: #491620)
+
+Add support for setting the default hash algorithm used in b-tree
+directories in tune2fs (from a command-line option) or mke2fs (via
+mke2fs.conf). In addition, change the default hash algorithm to
+half_md4, since it is faster and better.
+
+The blkid library will now recognize MacOS hfsx filesystems, and
+correctly extract the label and uuid for hfs, hfsx, and hfsplus
+filesystems. (Addresses Sourceforge Feature Requests: #2060292)
+
+The blkid library has improved detection of JFS and HPFS filesystems.
+(Addresses Launchpad Bug: #255255)
+
+The blkid library is now much more efficiently handling devicemapper
+devices, mainly by no longer using the devicemapper library. This can
+speed up access for systems with a large number of device mapper
+devices.
+
+Blkid had a number of cache validation bugs in libblkid that have been
+fixed. (Addresses Debian Bug: #493216)
+
+Resize2fs will now properly close out the "updating inode references"
+progress bar so there is a newline printed before printing the final
+"resize is successful" message.
+
+Resize2fs will now correctly handle filesystems with extents and/o
+uninitialized block groups correctly when file/directory blocks need
+to relocated (i.e., when shrinking a filesystem or if the resize_inode
+is not present). To support this, the ext2fs library now supports
+initializing inode and block bitmaps that are not yet initialized when
+allocating them using ext2fs_new_block() and ext2fs_new_inode(). In
+addition, e2fs_block_iterate2() can now support changing the location
+of interior nodes of an extent tree, and ext2fs_extent_set_bmap() has
+been optimized to avoid creating unnecessary new extents when updating
+the location of blocks in the extent tree. This will also help out
+e2fsck's recovery of obscurely corrupted filesystems with extents,
+when blocks are claimed by multiple inodes.
+
+Add support for on-line resizing ext4 filesystem with the flex_bg
+filesystem feature. The method for doing so is not optimal, but to do
+a better job will require kernel support.
+
+E2fsprogs 1.41.0 intrduced a bug in libext2fs which casued e2image and
+debugfs programs to not be able to read e2image files; the signed
+vs. unsigned bug in the code which read bitmaps from the e2image has
+been fixed. (Addresses Debian Bug: #495830)
+
+Resize2fs is now correctly managing the directory in-use counts when
+shrinking filesystems and directory inodes needed to be moved from one
+block group to another. This bug has been around since e2fsprogs
+1.26, and is largely harmless, but does cause a filesystem corruption
+which will be flagged by e2fsck after the filesystem has been shrunk.
+
+E2fsck will no longer issue spurious complaints about the inode size
+caused by very large extent-based files, and by blocks reallocated
+using fallocate() with the FALLOC_FL_KEEP_SIZE option. (Addresses
+Kernel Bugzilla: #11341)
+
+Mke2fs will now set the creation timestamp on the lost+found directory
+and the root directory. (More generally, all new inodes created using
+the ext2fs library will correctly set the creation timestamp.)
+
+E2fsck now correctly calculates ind/dind/tind statistics in the
+presence of extent-based files. In addition, "e2fsck -v" will report
+statistics of the depth of extent trees in the filesystem. E2fsck can
+also give an inode fragmentation report using "e2fsck -E fragcheck"
+which can be useful when debugging the kernel block allocation
+routines.
+
+Fix support for empty directory blocks in ext4 filesystems with 64k
+blocksize filesystems.
+
+E2fsck will now print the depth of corrupt htree directories.
+
+Debugfs's htree command now correctly understands extent-based
+directories. It will also print out the minor hash as well as the
+major hash.
+
+Debugfs has a new command which will print the supported features of
+e2fsprogs, to enable scripts to know whether the installed version of
+e2fsprogs can support a specific feature.
+
+Debugfs will now write files using extents for filesystems that
+support them.
+
+The error message printed by "tune2fs -I" if the inode size was too
+small was rather confusing, so it has been improved. Also, we won't
+try to create an undo log until we know that command-line-specified
+parameters such as "tune2fs -I <inode size>" are valid.
+
+Given some filesystems found "in the wild" that had non-zero block
+group checksums even though the uninit_bg/gdt_sum feature was not
+enabled, e2fsck would issue spurious error messages. Teach
+ext2fs_group_desc_csum_verify() to ignore the block group checksum
+entirely if the feature flag is not set. (Addresses Debian Bug:
+#490637)
+
+The blkid program will now print out a user-friendly listing of all of
+the block devices in the system and what they contain when given the
+-L option. (Addresses Debian Bug: #490527)
+
+The filefrag program now has a more accurate calculation for the
+number of ideal extents. (Addresses Debian Bug: #458306)
+
+The test I/O manager is now enabled by default, but its overhead is
+only incurred when it would be enabled via the TEST_IO_FLAGS or
+TEST_IO_BLOCK environment variables.
+
+Typographical errors in various program strings and usage messages
+have been fixed; most of these were pointed out by the e2fsprogs
+message catalog translators. (Thanks, translators!)
+
+Update and clarified various man pages, as well as some typographical
+errors in the libext2fs texinfo file.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Add Indonesian and update French, Polish, Dutch, German, Sweedish,
+Czech, and Vietnamese Translations. (Addresses Debian Bugs: #313697,
+#401092)
+
+Programmer's Notes
+------------------
+
+Fix portability problem with the badblocks group; for systems that
+don't have nanosleep(), try using usleep() instead.
+
+The "make check" target in the e2fsck directory now sets
+LD_LIBRARY_PATH before running the various e2fsck internal library
+regression tests.
+
+The crc32 regression test in the e2fsck library is now portable to
+greater varienty of environments, including big-endian systems and
+when cross-building e2fsprogs for embedded systems. (Addresses
+Sourceforge Bug: #2019287)
+
+The ext2fs_extent_set_bmap() had some bugs when setting the first
+block in a file, or when replacing a single block extent. Those cases
+fortunately were came up relatively rarely when e2fsck was checking
+files, but caused some problems when resize2fs was shrinking
+extent-based files.
+
+Fix a potential core-dumping bug in libe2p's iterate_on_dir()
+function.
+
+Various ext2fs library functions --- ext2fs_block_iterate2(),
+ext2fs_initialize() and ext2fs_extent_open() --- now correctly free
+allocated memory to avoid memory leaks in all of their error return
+paths.
+
+Ext2ed was failing to build because masix support had been removed in
+the rest of e2fsprogs, so ext2ed no longer has masix support, either.
+
+The configure script now respects the LDFLAGS environment variable if
+it is set when configure is called. (Addresses Sourceforge Feature
+Request: #1937287)
+
+Libuuid is now more portable to the Windows platform. (Addresses
+Sourceforge Feature Request: #1937287)
+
+The configure script now uses AC_MSG_{RESULT,WARN,ERROR} instead of
+bare echo commands so that configure flags such as --quiet work
+correctly. (Addresses Sourceforge Patches: #2058794)
+
+A few uses of sprintf have been removed from the ext2fs library to
+make life easier for bootloaders with a limited libc environment.
+(Addresses Sourceforge Bug: #2049120)
+
+The ext2fs_read_inode() checks the validity of the inode number passed
+to it earlier, to avoid doing some needless work when it would fail
+anyway.
+
+The ext2fs_open() checks the validity of the blocksize parameter
+passed to it earlier, to avoid doing some needless work when it would
+fail anyway.
+
+Disable a very annoying automatic "%.sh -> %" GNU make rule in the
+top-level Makefile. That automatic rule is used to better support
+SCCS, but it caused problems for a particular niche distribution which
+likes to use configure.sh files to store the configure options used to
+build a package. Unfortuntaely GNU make will use the configure.sh to
+replace the configure script, resulting in a self-inflicted fork bomb
+leading to an out-of-memory crash.
+
+To support old GNU C compilers don't use C99/C++ comments, but only
+K&R style comments, and don't try to use __builtin_expect if __GNUC__
+is less than 3. (__builtin_expect is only supported for gcc versions
+2.96 and up, and it's tricky to check for gcc 2.95 vs gcc 2.96; since
+this is an optimization, we only try to use __builtin_expect for gcc 3
+and up.)
+
+In e2fsck's crc routines, make sure we use WORDS_BIGENDIAN instead of
+__LITTLE_ENDIAN, which are only defined by glibc's header files and
+hence isn't portable.
+
+For the convenience for some distributions that need a static tune2fs,
+the Makefile for misc/ now has a tune2fs.static target.
+
+The ext2fs_block_iterate2() function now supports BLOCK_FLAG_APPEND
+for extent-based files
+
+The ext2fs_bmap() function now supports BMAP_ALLOC for extent-based
+files.
+
+All source files no longer have any trailing white space.
+
+The io_channel_read_blk64() and io_channel_write_blk64() functions are
+now functions instead of C preprocessor macros to provide better
+forward compatibility.
+
+The e2fpsrogs translation template now expands the @x abbrevation.
+
+Various namespace leackages in libblkid, libe2p, and libext2fs have
+been fixed.
+
+Fix a parallel build problem in e2fsprogs.
+
+E2fsprogs is now more portable to Solaris.
+ * blkid no longer assumes that the TIOCGSIZE and TIOCGWINSZ ioctl's
+ are always present.
+ * Scripts do not assume that /bin/true is always in /bin
+ * Don't use __FUNCTION__ since Solaris's C99 doesn't support it.
+ * Flush stdio handles before calling setbuf(), since Solaris will
+ discard any pending output to the stream.
+ * Define _XOPEN_SOURCE to 600 since Solaris's header files are very
+ picky about which C compiler can beused for SUSv3 conformance.
+ Use of C99 is not compatible with SUSv2 (_XOPEN_SOURCE=500),
+ and C89 is not compatible with SUSv3 (_XOPEN_SOURCE=600).
+ Since we need some SUSv3 functions, consistently use SUSv3 so
+ that e2fsprogs will build on Solaris using c99.
+ * Solaris C99 does not support varargs C preprocessor macros
+ * Solaris header files pollute the C namespace if in/netinet.h
+ is included, which conflicts with e2fsprogs' use of the kmem_cache_t
+ typedef.
+ * Solaris ships with a pathetically ancient shell in /bin/sh so we
+ avoid the use of various more avanced shell constructs such as $().
+
+The "make rpm" command will now take some extra configure optiosn from
+the build environment without needing to patch the source tree.
+
+The ext2fs_add_dir_block() function will now grow the dblist more
+aggressively as an optimization to avoid copying the array too often.
+
+The e2fsck_write_bitmaps() will write the block and inode bitmaps
+together instead of in two passes.
+
+
+E2fsprogs 1.41 (July 10, 2008)
+==============================
+
+Add support for ext4 filesystem features, in particular extents,
+uninit_bg, flex_bg, huge_file, and dir_nlink features. Also add
+support for checking journal checksums. Debugfs will print new
+superblock and inode fields that were defined for ext4. For example,
+the nanosecond and i_version fields of an inode, and the
+s_min_extra_isize and s_wanted_extra_isize fields from the superblock.
+Note: Resize2fs doesn't currently support the combination of flex_bg
+and !resize_inode. (Addresses Debian Bug: #388452, #425477)
+
+Tune2fs can support migrating a filesystem from using 128 byte inodes
+to 256 byte inodes, so it can take advantage of the full features of
+ext4.
+
+Add support for "undo" support. E2fsck and mke2fs can optionally
+record an undo log which can replayed by the program e2undo.
+
+E2fsck could damage a filesystem by trying to relocate inode tables
+due to corrupted block group descriptors, where the attempted inode
+table relocation would do far more harm than good. E2fsck has been
+fixed to detect this these sorts of corrupted block group descriptors
+much earlier in e2fsck processing, so it can try to use the backup
+superblock and block group descriptors first. This should be a much
+better strategy for recovering these types of corrupted filesystems.
+(Addresses Sourceforge Bug: #1840291)
+
+E2fsck will display a more understandable message when the last check
+field in the superblock is in the future. (Addresses Debian Bug:
+#446005).
+
+E2fsck now performs more extensive and careful checks of extended
+attributes stored in the inode.
+
+Enhance mke2fs to print a more explanatory error message when
+ext2fs_get_device_size() returns EFBIG. (Addresses Debian Bug:
+#488663)
+
+Fix mke2fs to use a default block size of 4k when formatting an
+external journal device. This is done by using a fixed filesystem
+type list that consists only of the single filesystem type "journal"
+when looking up configuration keys in /etc/mke2fs.conf. (Addresses
+Debian Bug: #488663)
+
+Speed up how mke2fs writes the journal data blocks by writing the disk
+blocks in larger chunks.
+
+Fix blkid handling of stale devices. Fix a bug which could cause a
+core dump while garbage collecting the blkid cache, and assure that
+blkid_find_dev_with_tag() never returns a non-existent device. Also,
+if a filesystem is found at a new /dev location, eliminate any
+duplicate stale entries which can not be verified.
+(Addresses Debian Bugs: #487758, #487783)
+
+Add more paranoid checks for LVM volumes and swap partitions in
+blkid's probe function, to reduce the chances of false positives.
+
+The mke2fs program now has a much more sophisticated system for
+controlling configuration parameters of a newly created filesystem
+based on a split filesystem and usage type system. The -t option to
+mke2fs was a deprecated alias to -c; it now specifies a filesystem
+type (ext2, ext3, ext4, etc.), while the -T option can now be a comma
+separated usage list. The filesystem type information and type
+information is used to extract configuration parameters from the
+/etc/mke2fs.conf file.
+
+The mke2fs program will no longer complain and request the -f option
+when the user tries to create a filesystem with greater than 2**31
+blocks.
+
+When creating a filesystem for the GNU Hurd use a fs-type of Hurd and
+adjust the mke2fs.conf file so filesystems for the Hurd are created
+with a blocksize of 4096 and inode size of 128, which is all it knows
+how to handle. (Addresses Debian Bug: #471977)
+
+Mke2fs will always make sure that lost+found always has at least 2
+blocks, even for filesystems with very large blocksizes (i.e., 64kb).
+
+Resize2fs will now print the minimum needed filesystem size if given
+the -P option, and will resize the filesystem to the smallest possible
+size if given the -M option.
+
+Fix resize2fs to clean up the resize_inode if all of the reserved gdt
+blocks are consumed during an off-line resize.
+
+The "ls" command in debugfs now supports the -p option, which causes
+it to quote the filenames so that spaces or tabs in directory entries
+are easily visible. (Addresses Red Hat Bugzilla: #149480; Addresses
+Sourceforge Feature Request: #1201667)
+
+Fix a potential off-by-one buffer oveflow in the fs_device_name in an
+e2image file.
+
+The chattr program will return a non-zero exit code in case of
+failures, and error messages can be suppressed with the -f option.
+(Addresses Red Hat Bugzilla: #180596)
+
+Fix a bug in badblocks which caused it to overrun an array and likely
+crash if more than 8 test patterns are specified using the -t option.
+(Addresses Debian Bug: #487298)
+
+Add support to badblocks to limit how quickly it reads from the disk
+drive (so it can be used for background scrubbing), and so it will
+abort after finding a given number of errors.
+
+Remove support for the legacy big-endian filesystem format which only
+existed on extremely long-dead PowerPC kernels almost a decade ago.
+
+Remove MASIX support from e2fsprogs.
+
+Add I/O statistics reporting to e2fsck.
+
+Update Vietnamese, Polish, French, Spanish, German, Catalan, Dutch,
+Czech translations.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #487443, #487675, #490003)
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.

+Programmer's Notes
+------------------
+
+Factor out bitmap code in preparation for adding 64-bit new-style
+bitmaps.
+
+Fix gcc -Wall warnings
+
+Fix the pkg-config files so that private librares are specified in
+"Libs.private:".
+
+Fix the libext2fs.texinfo manual so it builds with modern versions of
+texinfo.
+
+Silence the makefile from showing the awk command used to build the
+
+Clean up the badblocks group so to make it more portable and robust.
+
+Avoid using predictable filenames in /tmp in blkid's regression test
+suite. Also remove bashism's in the regression test script.
+
+If the configure script is given --with-diet-libc, don't use thread
+local storage, since diet libc doesn't support TLS. (Addresses
+Sourceforge Bug: #2000654)
+
+Fix the blkid regression test suite to tolerate older versions of
+mkswap that don't support the -U option.
+
+A few library routines have been converted to support 64-bit block
+numbers; in particular, the I/O manager functions, the test_io,
+inode_io, and unix_io managers have all be converted to support 64-bit
+operation.
+
+Debugfs can now be extended for use by test programs. See
+lib/ext2fs/extents.c for an example for how it can be used. The test
+program links against the debugfs object files, and provides
+additional commands by defining an auxiliary libss command table.
+
+The lazy_bg filesystem feature, which was only used by developer's
+testing, has been removed since it has been largely supplanted by
+uninit_bg. This also simplifies the code.
+
+
+E2fsprogs 1.40.11 (June 17, 2008)
+=================================
+
+Mke2fs, tune2fs, and resize2fs now use floating point to calculate the
+percentage of reserved blocks. (Addresses Debian Bug: #452639)
+
+Updated Spanish and Catalan translations.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #483962, #483023)
+
+Add detection for ZFS volumes to the libblkid library.
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+(Addresses Debian Bug: #486463)
+
+Programmer's notes:
+-------------------
+
+Fix marginal C code in probe_lvm2() function to the blkid library more
+portable for older compilers.
+
+Fix build problems on MacOS X. (Addresses Sourceforge Bug: #1972473)
+
+Fix ext2fs_swap{16,32,64} functions so they can be used by external
+applications on big-endian machines. (Addresses Debian Bug: #484879)
+
+
+E2fsprogs 1.40.10 (May 21, 2008)
+================================
+
+When deciding whether or not to revalidate a blkid cache entry, if the
+device's mtime is newer than the last time the cached entry was
+validated, force a revalidation.
+
+Fix a potential data corruption bug in e2fsck in the journal replay.
+The chances of this is happening is extremely remote, especially the
+default data=ordered or data=writeback modes. However, if a block
+which has been journalled starts with the first four bytes 0xc03b3998,
+when e2fsck replays the journal, those four bytes will be replaced
+with zero's. Fortunately, it is highly, highly unlikely for e2fsck
+metadata to begin with those fatal 4 byte sequence, and unless
+data=ordered mode is in use, data blocks are never journaled.
+
+Updated German, Dutch, Sweedish, and Vietnamese translations.
+
+Programmer's notes:
+-------------------
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Remove default sizes of types when cross compiling, since autoconf
+2.50 can figure this out automatically now.
+
+
+E2fsprogs 1.40.9 (April 27, 2008)
+=================================
+
+SuSE's security team audited uuidd and came up with a few minor
+issues. None of them are serious given that uuidd runs setuid as a
+unprivileged user which has no special access other than libuuid
+directory, but it's good to get them fixed.
+
+One additional fix in ext2fs_swap_inode_full() needed for resize2fs to
+work correctly with in-inode extended attributes.
+
+Updated German, Czech, Dutch, French, Polish, Sweedish, and Vietnamese
+translations.
+
+Debugfs will avoid using a pager if the standard output is not a tty.
+
+Fix debugfs and tune2fs to correctly handle daylight savings time when
+parsing a time string.
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+
+Fix fsck completion bars when multiple filesystems were being checked
+in parallel. (Addresses Debian Bug: #432865, Addresses Launchpad Bug:
+#203323, Addresses Sourceforge Bug: #1926023)
+
+Fix fsck so that progress information is sent back correctly when
+multiple filesystems are being check and the output of fsck is being
+redirected to a file descriptor. Also, include the device name (w/o
+spaces) in the progress information sent back via a file descriptor.
+(Addresses Launchpad Bug: #203323, Addresses Sourceforge Bug:
+#1926023)
+
+Teach fsck to treat "ext4" and "ext4dev" as ext* filesystems.
+
+If logsave receives a SIGTERM or SIGINT signal, it will now pass that
+signal to its child process.
+
+Fix mke2fs's creation of are resize inode when there is a non-standard
+s_first_data_block setting.
+
+Fix bug in blkid when run by an unprivileged user; most devices were
+not reported correctly. 9Addresses Launchpad Bug: #220275)
+
+Mke2fs will not allow the logically incorect combination of
+resize_inode and meta_bg, which had previously caused mke2fs to create
+a corrupt fileystem.
+
+Fix fsck in German locales so that a 'j' means yes.
+(Addresses Sourceforge Bug: #1947683)
+
+
+Programmer's notes:
+-------------------
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Update valgrind options in test_script to work with valgrind 3.2.3
+
+Update texinfo.tex to a much newer version from the FSF.
+
+Remove bashism for configure script and from the lib/ss Makefile.
+Addresses Sourceforge Bug: 1921969
+
+Fix some silently broken tests: m_no_opt, m_meta_bg, and m_raid_opt.
+
+Fix build system so that if texinfo is not installed, it won't print a
+(harmless) error message.
+
+
+E2fsprogs 1.40.8 (March 13, 2008)
+=================================
+
+Fixed e2image -I so it works on image files which are larger than 2GB.
+
+Fixed e2fsck's handling of directory inodes with a corrupt size field. If
+the size is larger than the number of blocks found in the inode, don't
+try to allocate extra empty blocks at the end of the directory to make
+up the difference; there's no point to doing that. In addition, if
+the size is not a multiple of a blocksize, always fix it.
+
+E2fsck handled a pass 2 "should never happen error" by not giving
+enough information and then core dumping. Unfortunately, it was all
+too easy to trigger the "should never happen" situation if a
+directory's inode size was not correct. This has been fixed, but
+e2fsck has also been taught how to handle this situation more
+gracefully, by simply removing the inode hash tree information, so
+that it can be rebuilt again after e2fsck's pass 3. (Addresses
+Launchpad Bug: #129395)
+
+Resize2fs had a bug resizing large inodes with extended attributes
+that was fixed in 1.40.6; unfortunately, it turned out it wasn't fixed
+completely on big-endian systems such as PowerPC. The bug should be
+completely fixed now. Yay for regression test suites. (Addresses Red
+Hat Bugzilla: #434893)
+
+Updated German, Czech, Dutch, Polish, Sweedish, and Vietnamese
+translations. Many thanks to Philipp Thomas from Novell for stepping
+up to become the new German translation maintainer! (Addresses Debian
+Bugs: #302512, #370247, #401092, #412882).
+
+When e2fsck is clearing a corrupt inode's HTREE directory information,
+make it clear that it is just clearing the HTREE information, not the
+entire inode.
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+
+Programmer's notes
+------------------
+
+Add new functions, ext2fs_dblist_get_last() and
+ext2fs_dblist_drop_last(), which allows the caller to examine the last
+directory block entry added to the list, and to drop if it necessary.
+
+Fixed a portability problem in libblkid with DJGPP.
+
+Fix an obvious typo in an "internal error" message in e2fsck. Thanks
+to Philipp Thomas for pointing this out.
+
+If the info files are not built, change "make install" so it doesn't
+fail with an error code.
+
+
+E2fsprogs 1.40.7 (February 28, 2008)
+====================================
+
+Remove support for clearing the SPARSE_SUPER feature from tune2fs, and
+depreciate the -s option, since it can result in filesystems which
+e2fsck can't fix easily. There are very good reasons for wanting to
+disable sparse_super; users who wants to turn off sparse_super can use
+debugfs. (Addresses Sourceforge Bug: #1840286)
+
+Add missing options to mke2fs's usage message. (Addresses Sourceforge
+Bug: #1751393)
+
+Fix bug in resize2fs when large (greater than 128 byte) inodes are
+moved when a filesystem is shrunk; it was only moving the first 128
+bytes, so extended attributes were not getting moved. (Addresses Red
+Hat Bugzilla: #434893)
+
+E2fsck now prints an explicit message when the bad block inode is
+updated, to avoid confusion about why the filesystem was modified.
+(Addresses Sourceforge Bug: #756460)
+
+Allow mke2fs and tune2fs manipulate the large_file feature.
+Previously we just let the kernel and e2fsck do this automatically,
+but e2fsck will no longer automatically clear the large_file feature.
+It still isn't really necessary to worry about this feature flag
+explicitly, but some users seem to care. (Addresses Red Hat Bugzilla:
+#258381)
+
+Suppress message about an old-style fstab if the fstab file is empty.
+(Addresses Debian Bug: #468176)
+
+Fix (really minor) bug in debugfs's find_free_block so it avoids
+reporting a free block more than once if there are too few free blocks
+in the filesystem. (Addresses Sourceforge Bug: #1096315)
+
+Change e2fsck to no longer clear the LARGE_FILES feature flag
+automatically, when there are no more > 2GB files in the filesystem.
+It's been almost a decade since there have been kernels that don't
+support this flag, and e2fsck clears it quietly without telling the
+user why the filesystem has been changed.
+
+Fix bug which could cause libblkid to seg fault if a device mapper
+volume disappears while it is being probed. (Addresses RedHat
+Bugzilla: #433857)
+
+Inhance e2fsck's reporting of unsupported filesystem feature flags.
+(Addresses Sourceforge Feature Request: #1175808)
+
+Fix option syntax in dumpe2fs for explicit superblock and blocksize
+parameters. What was currently documented in the man page has been
+broken for some time, due to getopt() implementation changes. The
+option sytax has been changed to one which is can be more portable
+supported and which is consistent with the format for extended options
+in mke2fs and tune2fs. (Addresses Sourceforge Bug: #1830994)
+
+Add support to tune2fs to clear the resize_inode feature. This
+requires an fsck afterwards. (Addresses Red Hat Bugzilla: #167816)
+
+Teach blkid to detect LVM2 physical volumes. (Addresses Red Hat
+Bugzilla: #409321)
+
+Add support for setting RAID stride and stripe-width via mke2fs and
+tune2fs. Teach dumpe2fs to print the RAID parameters.
+
+Add support for setting new superblock fields to debugfs's
+set_super_value.
+
+Add support for printing "mostly-printable" extended attributes in
+Debugfs.
+
+Add support for the -M option to fsck, which causes it to ignore
+mounted filesystem.
+
+Fix uuidd so that it creates the pid file with the correct pid number.
+(Addresses Sourceforge Bug: #1893244)
+
+Fix various gcc -Wall warnings.
+
+Update Czech, Dutch, Polish, Sweedish, and Vietnamese translations
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+(Addresses Sourceforge Patch: #1399325)
+
+
+Programmer's notes:
+-------------------
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bug: #466929)
+
+Add new flag EXT2_FLAG_NONFREE_ON_ERROR ext2fs_open2() which returns a
+partially filled-in filesystem object on an error, so that e2fsck can
+print more intelligent error messages.
+
+Add a new function e2p_edit_feature2() which allows the caller to
+specify which feature flags are OK to set or clear, and which returns
+more specific information about feature flags which are not allowed to
+be set/cleared.
+
+Set the C locale in the test_script driver since it uses [A-Za-z].
+(Addresses Sourceforge Bug: #1890526)
+
+Use fcntl locking instead of lockf in libuuid since Cygwin doesn't
+support lockf().
+
+Change configure.in to avoid using the 'dc' command unless it is
+absolutely needed. (i.e., when using parsing a WIP-style version
+number) (Addresses Sourceforge Bug: #1893024)
+
+Add portability checks to support compilation under DJGPP.
+
+Update to the latest samba tdb code before the LGPLv3 change, which

+
+Fix memory leak in ext2fs_alloc_block().
+
+Fix makefile dependency issues for various install targets.

+Improve descriptions for the r_move_itable and r_resize_inode tests.
+
+
+E2fsprogs 1.40.6 (February 9, 2008)
+===================================
+
+Add support for returning labels for UDF filesystems in the blkid
+library.
+
+Fix bug in the blkid library where cached filesystems was not being
+flushed when opening USB devices returned the error ENOMEDIUM.
+(Addresses Debian Bug: #463787)
+
+Added logic to the blkid library to automatically choose whether a
+filesystem should be mounted as ext4 or ext4dev, as appropriate.
+
+Allow tune2fs to set and clear the test_fs flag on ext4 filesystems.
+
+Fix a bug in e2fsck which caused it to core dump if e2fsprogs had been
+configured with --enable-jbd-debug.
+
+Document the BLKID_FILE environment variable in the libblkid man page
+
+Programmer's Notes:
+-------------------
+
+Update e2fsprogs translation template and Vietnamese and Czech translations
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #436058)
+
+Don't try to create $DESTDIR/etc/init.d as part of make install as we
+don't install the init.d script (and it's not the recommended way to
+start uuidd anyway). (Addresses Sourceforge Bug: #1885085)
+
+Use thread local storage to fix a theoretical race condition if two
+threads try to format an unknown error code at the same time in the
+com_err library.
+
+
+E2fsprogs 1.40.5 (January 27, 2008)
+===================================
+
+Fix a potential overflow big in e2image if the device name is too
+long.
+
+Mke2fs will now create new filesystems with 256 byte inodes and the
+ext_attr feature flag by default. This allows for much better future
+compatibity with ext4 and speeds up extended attributes even on ext3
+filesystems.
+
+Teach e2fsck to ignore certain "safe" filesystem features which are
+set automatically by the kernel. Having the kernel set features
+automagically behind the user's back is a bad idea, and we should try
+to break the kernel of this habit, especially for the newer ext4
+feature flags. But for now, we will try to avoid needless full checks
+which can annoy users who are doing fresh installs.
+
+Add support in tune2fs and mke2fs for making a filesystem as being "ok
+to be used with test kernel code". This will be needed for using test
+filesystems with the latest ext4 kernel code.
+
+Change e2fsck -fD so that it sorts non-htree directories by inode
+numbers instead of by name, since that optimizes performances much
+more significantly. (Addresses-Sourceforge-Feature-Request: #532439)
+
+If e2image fills the disk, fix it so it exits right away instead of
+spewing large numbers of error messages.
+(Addresses-Sourceforge-Feature-Request: #606508)
+
+If ftruncate64() is not available for resize2fs, let it use ftrucate()
+instead, but have it check to see if the size would get truncated, and
+skip calling ftruncate in that case.
+
+Add support for detecting HFS+ filesystems in the blkid library.
+
+Add supprt in the blkid library for ext4/ext4dev filesystems.
+
+Fix a bug in blkid where it could die on a floating point exception
+when presented with a corrupt reiserfs image.
+
+Fix blkid's handling of ntfs UUID's so that leading zeros are printed
+such that UUID string is a fixed length.
+
+Add sample python bindings for the uuid library to the contrib
+directory. (Addresses-Sourceforge-Patches: #778817)
+
+Fix debugfs's 'lsdel' command so it uses ext2fs_block_iterate2 so it
+will work with large files. (Addresses Sourceforge Feature Request:
+#1257500 and Sourceforge Support Request: #1253511)
+
+Allow the debugfs 'undel' command to undelete an inode without linking
+it to a specific destination directory, since this might require
+allocating blocks that could overwrite some yet-to-be-recovered
+deleted files. (Addresses-Sourceforge-Feature-Request: #967141)
+
+Update Swedish translations from the Translation Project.
+
+Programmer's Notes:
+-------------------
+
+Fix configure handling of --sbindir (which should rarely be used, but
+someone did complain, so let's fix it). (Addresses Sourceforge Bug:
+#498381)
+
+Updated e2fsprogs.spec file to include a new uuidd package
+
+Use pkg-config to determine where to find the devmapper library so we

+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs: #459403, #459475, #459614)
+
+Remove the --enable-dynamic-static configure option, and build e2fsck
+dynamically by default. If the user wants e2fsck.static, he/she will
+need to build it via "make -C e2fsck e2fsck.static"

+Fix various build warnings due to missing prototypes.
+(Addresses Sourceforge Patch: #1861663, #1861659)
+
+
+E2fsprogs 1.40.4 (December 31, 2007)
+====================================
+
+Improve time-based UUID generation. A new daemon uuidd, is started
+automatically by libuuid if necessary. This daemon is setuid to allow
+updates to /var/lib/libuuid, so the clock sequence number can be
+stored and so if the clock is set backwards, it can be detected.
+(Addresses Sourceforge Bug: #1529672, Addresses Red Hat Bugzilla:
+#233471)
+
+Filter out the NEEDS_RECOVERY feature flag when writing out the backup
+superblocks. This avoids e2fsck from concluding that a full
+filesystem check is required before backing up the superblock due to
+changes in the feature flags. (Addresses Debian Bug: #454926)
+
+Fix fsck to only treat the '#' character as a comment at the beginning
+of the line in /etc/fstab. Otherwise fstabs for the fuse filesystem
+will cause fsck to issue an bogus warning message.
+(Addresses Gentoo bug: #195405, Addresses Sourceforge bug: #1826147)
+
+Format control characters and characters with the high eighth bit set
+when printing the contents of the blkid cache, to prevent filesystems
+with garbage labels from sending escape sequences to the user's screen
+that might, for example place it in graphics mode. (Addresses Ubuntu

+
+Fix sign-extension problem on 64-bit systems in in the com_err

+
+E2fsprogs 1.40.3 (December 5, 2007)
+===================================
+
+Fix a potential security vulnerability where an untrusted filesystem
+can be corrupted in such a way that a program using libext2fs will
+allocate a buffer which is far too small. This can lead to either a
+crash or potentially a heap-based buffer overflow crash. No known
+exploits exist, but main concern is where an untrusted user who
+possesses privileged access in a guest Xen environment could corrupt a
+filesystem which is then accessed by the pygrub program, running as
+root in the dom0 host environment, thus allowing the untrusted user to
+gain privileged access in the host OS. Thanks to the McAfee AVERT
+Research group for reporting this issue. (Addresses CVE-2007-5497.)
+
+Fix hueristics in blkid which could cause a disk without partitions to
+be incorrectly skipped when a loopback device is present. (Addresses
+Red Hat Bugzilla #400321.)
+
+Fix e2image so that in raw mode it does not create an image file which
+is one byte too large.
+
+Change mke2fs's usage message so it recommends the preferred -E option
+instead of the deprecated -R option.
+
+Enhance the blkid library so it will recognize squashfs filesystems.
+(Addresses Red Hat Bugzilla #305151.)
+
+Enhance e2fsck so it will force the backup superblocks to be backed up
+if the filesystem is consistent and key constants have been changed
+(i.e., by an on-line resize) or by e2fsck in the course of its
+operations.
+
+Enhance blkid's detection of FAT filesystems; so that USB disks with
+only a single bootable partition will not get missed.
+
+E2fsck will no longer mark a filesystem as invalid if it has time
+errors (i.e., if superblock mount time or last write time is in the
+future) and the user refuses to fix the problem.
+
+The Ubuntu init scripts don't properly set the system time correctly
+from hardware clock if the hardware clock is configured to tick local
+time instead of GMT time. Work around this as best as we can by
+providing an option, buggy_init_scripts, in /etc/e2fsck.conf which can
+be set on Ubuntu systems. (Addresses Debian Bug #441093, and Ubuntu
+Bug #131201.)
+
+Fix fsck to ignore /etc/fstab entries for bind mounts. (Addresses Red
+Hat Bugzilla #151533.)
+
+Fix e2fsck so that if the superblock is corrupt, but still looks
+vaguely like an ext2/3/4 superblock, that it automatically tries to
+fall back to the backup superblock, instead of failing with a hard
+error.
+
+Make the e2fsprogs program more robust so that they will not crash
+when opening a corrupt filesystem where s_inode_size is zero.
+
+Change e2fsck so it uses sscanf() instead of atoi() so it non-numeric
+arguments are detected as such and the parse error is reported to the
+user. (Addresses Debian Bug #435381.)
+
+Change e2fsck so it will not complain if a file has blocks reallocated
+up to the next multiple of a system's page size.
+
+Fix bug in ext2fs_check_desc() which will cause e2fsck to complain
+about (valid) filesystems where the inode table extends to the last
+block of the block group. (Addresses Red Hat Bugzilla #214765.)
+
+Fix a bug in ext2fs_initialize() which causes mke2fs to fail while
+allocating inode tables for some relatively rare odd disk sizes.
+(Addresses Red Hat Bugzilla #241767.)
+
+Add Catalan translation and update Dutch and Swedish translations
+from the Translation Project.
+
+Fix big-endian byte-swapping bug in ext2fs_swap_inode_full(). We
+still had an issue when trying to figure out whether we need to
+byte-swap fast symlinks that contained extended attributes.
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+(Addresses SourceForge Bug #1821333.)
+
+
+Programmer's Notes:
+-------------------
+
+Fix mke2fs tests to avoid needing any significant ^M (CR) characters
+
+Add "make check" to the RPM spec file
+
+Fix "make install" and 'make unstall" in misc/Makefile.in so that it
+works correctly when the prefix is not the root directory.
+
+Fix the resize2fs tests, r_move_itable and r_resize_inode, so they
+clena up after themselves by deleting the test.img temporary file
+after completing the test.
+
+Fixed a corner case bug ext2fs_unlink() when trying to delete the
+first directory entry in a directory block and the last directory
+entry in the previous directory block is not in use. Fortunately
+ext2fs_unlink() is only used by debugfs and e2fsck, and in e2fsck in
+places where it is extremely unlikely to run into this corner case.
+
+Fix missing dependency which would cuase parallel builds to fail.
+(Addresses Sourceforge Bug #1842331.)
+
+Fix a build error on newer gcc caused by lib/ext2fs/ismounted.c
+calling open(O_CREATE) with a missing mode parameter.
+
+Fix the test_ss.c in lib/ss so it can be used as an example
+application program for the library as well as a regression test
+suite.
+
+Fix ext2fs_dblist_dir_iterate() so that error codes and abort codes
+are properly passed back up through the call stack.
+
+E2fsprogs 1.40.2 (July 12, 2007)
+================================
+
+A recent change to e2fsck_add_dir_info() to use tdb files to check
+filesystems with a very large number of filesystems had a typo which
+caused us to resize the wrong data structure. This would cause a
+array overrun leading to malloc pointer corruptions and segfaults.
+Since we normally can very accurately predict how big the the dirinfo
+array needs to be, this bug only got triggered on very badly corrupted
+filesystems.
+
+Fix a bug in e2fsck which caused it to incorrectly salvange
+directories when the last entry's rec_len is bogusly too big. This
+resulted in a nonsense filesystem corruption to be reported, and
+required a second run of e2fsck to fully fix up the directory.
+
+Update tune2fs man page to include more discussion of reserved blocks
+(Addresses Launchpad bug #47817)
+
+Update Turkish, Polish, Dutch, and Vietnamese PO files from the
+Translation Project
+
+
+E2fsprogs 1.40.1 (July 7, 2007)
+===============================
+
+Fix bug which could cause libblkid to loop forever. When revalidating
+a partition where there is obsolete information in /etc/blkid.tab, we
+end up freeing a the type tag without clearing dev->bid_type, causing
+blkid_verify() to loop forever. (Addresses Debian Bug: #432052)
+
+The Turkish translation has a bug in it where it has the translation
+of "E@e '%Dn' in %p (%i)" to "E@E". This causes @E to be expanded at
+@E, recursively, forever, until the stack fills up and e2fsck core
+dumps. We fix this by making e2fsck stop @-expansions after a
+recursive depth of 10, which is far more than we need.
+(Addresses Sourceforge Bug: #1646081)
+
+Compile the default mke2fs.conf into mke2fs program. People are
+getting surprised by mke2fs creating filesystems with different
+defaults than earlier versions of mke2fs if mke2fs.conf is not
+present. So we now create a built in version of mke2fs.conf file
+which is used by mke2fs if the /etc/mke2fs.conf is not present.
+(Addresses SourceforgeBug: #1745818)
+
+Improve the config/parse_types.sh helper script. Fix a potential
+security problem if e2fsprogs is built as root (as Gentoo does!). In
+addition fix the script and how it is called from the configure script
+so that it does the right thing when cross-compiling. (Fixes Gentoo
+bug: #146903)
+
+Update Vietnamese, French, and Dutch PO files from the Translation
+Project. Also created a new e2fsprogs.pot file for translator.
+
+Fix bogus strip permission errors when building under Debian. When
+building the e2fsprogs dpkg's, the dh_strip command emits a large
+number of error messages caused by the permissions not being right.
+So run dh_fixperms before running dh_strip.
+
+Programmer's Notes:
+-------------------
+
+Add new function: profile_set_default(). This function sets the value
+of the pseudo file "<default>". If the file "<default>" had
+previously been passed to profile_init(), then def_string parameter
+will be parsed and used as the profile information for the "<default>"
+file.
+
+Fix mk_cmds's error reporting so that it is unambiguous that it is the
+mk_cmds script which is generating the error. (Obviates Gentoo patch:
+e2fsprogs-1.32-mk_cmds-cosmetic.patch)
+
+Fix the test suite to use LC_ALL instead of LANG. LC_ALL is the "high
+priority" environment variable that overrides all others, where as
+LANG is the lowest priorty environment variable. If LC_ALL is set, it
+doesn't matter whether LANG, LANGUAGE, LC_COLLATE, LC_MESSAGES, and
+the all the rest are set. This will assure that the locale when
+running the test suites is the "C" locale. (Obviates Gentoo patch:
+e2fsprogs-1.38-tests-locale.patch)
+
+
+E2fsprogs 1.40 (June 29, 2007)
+==============================
+
+Fix divide by zero error in blkid's NTFS probing logic.
+
+Add new blkid -g option which causes the blkid cache to be garbage
+collected.
+
+Fix a bug in libblkid which could cause the internal field bid_type to
+become corrupted. Fortunately bid_type isn't used much, and bid_label
+and bid_uuid is only used by debugging code, so the impact of this bug
+was very minor.
+
+Mke2fs will now store the RAID stride value when a filesystem is
+created with a requested RAID stride, and then use it automatically in
+resize2fs.
+
+Mke2fs has a sanity check added to make sure (inode_size * num_inodes)
+isn't too big. In some cases Lustre users have tried specifying an
+inode size of 4096 bytes, while keeping an inode ratio of one inode
+per 4096 bytes.
+
+Improve sanity check in e2fsck's algorithm for finding a backup
+superblock, so that it won't accidentally find a superblock that was
+located in the journal, and then later reject it as being not a valid
+backup superblock.
+
+Fix e2fsck get_size logic so that it will work with the Linux floppy
+driver. The Linux floppy driver is a bit different from the other
+block device drivers, in that if the device has been opened with
+O_EXCL, it disallows another open(), even if the second open() does
+not have the O_EXCL flag. (Addresses Debian Bug: #410569)
+
+Fix error checking of badblock's last-block and start-block arguments.
+(Addresses Debian Bug: #416477)
+
+Fix e2fsck so that it doesn't overwrite the backup superblocks when
+recovering a journal until the master superblock has been confirmed as
+being sane.
+
+Change the blkid library to be much more paranoid about concluding
+that a partition contains an NTFS filesystem, and fetch the UUID and
+LABEL information from NTFS filesystems. (Addresses Launchpad Bug:
+#110138)
+
+Factor out the code which sets the default journal size and move it
+into libext2fs.
+
+Enhance e2fsck so it will recreate the ext3 journal if the original
+journal inode was cleared to due it being corrupt after finishing the
+filesystem check.
+
+Fix e2fsck so that it updates the journal inode if it is corrupted and
+the backup journal information from the superblock was successfully
+used to recover the filesystem.
+
+Fix e2fsck so that it checks all of the blocks in the journal inode
+for validity. The original code only checked the direct blocks to
+make sure the journal inode was sane. Unfortunately, if some or all
+of the indirect or doubly indirect blocks were corrupted, this would
+not be caught.
+
+Add support in blkid to detect LUKS encrypted partitions.
+
+Add extra sanity checks for extended attributes in the case where the
+size is zero but the offset is very large.
+
+Fix byte-swapping issues for large inodes in ext2fs_read_inode_full()
+and ext2fs_get_next_inode_full().
+
+Clarify the copyright licenses used by the various libraries in
+the top-level COPYING file (Red Hat Bugzilla: 166058)
+
+Make mke2fs's defaults when /etc/mke2fs.conf doesn't exist more sane.
+
+Fix mke2fs and debugfs to support large (> 16 bit) uid's and gid's.
+
+Remove check in e2fsck which requires EA's in inodes to be sorted;
+they don't need to be sorted, and e2fsck was previously wrongly
+clearing unsorted EA's stored in the inode structure.
+
+Allow mke2fs or tune2fs to create a substantially larger journal (up
+to 10,240,000 blocks).
+
+Fix MD superblock detection, and make sure the correct UUID is
+reported from the MD superblock.
+
+Fix a signed vs. unsigned bug in debugfs.
+
+Enhance debugfs's date parser so that it accepts integer values.
+
+Fix e2fsck's pass1c accounting so it doesn't terminate too early if a
+file with multiply claimed blocks is hard linked. or not at all if the
+root directory contains shared blocks
+
+Enhance debugfs so it can modify the block group descriptors using the
+command set_block_group_descriptor.
+
+Improve e2fsck's reporting of I/O errors so it's clearer what it was
+trying to do when an error happens
+
+Fix a bug in in how e2fsprogs byte swaps inodes containing fast
+symlinks that have extended attributes. (Addresses Red Hat Bugzilla:
+#232663 and LTC Bugzilla: #27634)
+
+Fix potential file descriptor leak in ext2fs_get_device_size() in an
+error case.
+
+Add libreadline.so.5 support to libss.
+
+Impove badblocks -n/-w exclusive usage message.
+
+Fix dump_unused segfault in debugfs when a filesystem is not open
+
+Fix memory leak in blkid library. (Addresses Debian Bug: #413661)
+
+Allow the debugfs lcd command to work w/o a filesystem being open.
+(Addresses LTC Bugzilla #27513)
+
+Fix e2fsck to clear i_size for special devices with a bogus i_blocks
+field on the first pass.
+
+Fix e2fsck to set the file type of the '..' entry when connecting
+a directory to lost+found. (Addresses Lustre Bug: #11645)
+
+Enhance e2fsck to recover directories whose modes field were corrupted
+to look like special files. This is probably only useful in
+artificial test cases, but it will be useful if we ever do the "inodes
+in directory" idea for ext4.
+
+Allow debugfs to dump (and rdump) > 2GB files. (Addresses Debian Bug:
+#412614)
+
+Fix resize2fs parsing of size parameter (in sector units). This was
+actually a bug in libe2p's parse_num_blocks() function. When handling
+the 's' suffix, it was ignoring the blocksize information passed in
+from the caller and always interpreting the number in terms of a 1k
+blocksize. (Addresses Debian Bug: #408298)
+
+There was a floating point precision error which could cause e2fsck to
+loop forever on really big filesystems with a large inode count.
+(Addresses Debian Bug: #411838)
+
+Fix memory leak in ext2fs_write_new_inode()
+
+Add support for using a scratch files directory to reduce e2fsck's
+memory utilization on really big filesystems. This uses the TDB
+library. See the [scratch_files] section of the e2fsck.conf man page
+for more details.
+
+Fixed type-punning bug which caused dumpe2fs to crash on the Arm
+platform (Addresses Debian Bug: #397044)
+
+Add explanatory message to badblocks that -n and -w are mutually exclusive
+(Addresses Debian Bug: #371869)
+
+Allow debugfs and dumpe2fs to support fs features under development.
+
+Add support for the new flag EXT2_FLAG_SOFTSUPP_FEATURES flag to
+ext2fs_open() , which allows application to open filesystes with features
+which are currently only partially supported by e2fsprogs.
+
+Allow unix_io to support offsets greater than 2G (Addresses
+SourceForge Bug: #1547922)
+
+Fixed overflow and signed/unsigned problems caused by the number of
+blocks or inodes exceeding 2**31 or being close to 2**32-1.
+
+Add support for unsigned directory hash calculations with hints in the
+superblock to fix cross-architectural portability for htree
+directories with filenames where the high 8th bit is set. (Addresses
+Debian: #389772)
+
+Fix resize2fs so that it gives user-intelligible error messages if the
+filesystem or the kernel does not support on-line resizing.
+(Addresses Debian Bug: #380548)
+
+Require mke2fs -F -F for really dangerous operations, since -F is
+needed for less dangerous operations such as creating filesystems
+images in regular files, or creating filesystems on whole block
+devices. These relatively innocuous usages should NOT be confused
+with running mke2fs on an apparently-mounted or in-use filesystem.
+
+Allow the default inode size to be specified into the mke2fs.conf
+file.
+
+Make the smallest default journal size is big enough so that on-line
+resizing should always work.
+
+Fix silly spelling error in e2fsck. (Addresses SourceForge bug:
+#1531372)
+
+Fix debugfs coredump when lsdel is run without an open filesystem
+(Addresses Debian Bug: #378335)
+
+Fix debugfs display bug us that bytes that have the high bit set are
+displayed as "ec" instead of "ffffffec".
+
+Add support in lsattr so it will display the EXT4_EXTENTS_FL flag.
+
+Device mapper scanning wasn't working in the blkid library because the
+pathnames had an extra "/dev" when they were being probed.
+
+Add GFS/GFS2 support to the blkid library.
+
+Fix blkid support of empty FAT filesystem labels.
+
+Avoid recursing forever (or for a long time) when the blkid library
+searches for a device and there are symlinks to directories in /dev.
+
+Avoid unaligned halfword access in blkid when accessing FAT
+superblocks, as this will cause Sparc/Solaris systems to throw a
+SIGBUS error.
+
+The latest devmapper libraries requires pthreads, add -lpthreads to
+the static link libraries for e2fsck.static if devmapper is enabled.
+(Addresses Debian bug: #388718)
+
+Improve the (non-installed, for experts only) findsuper program by
+printing the uuid and label from the superblocks, as well as the
+starting and ending offsets of the filesystem given the information in
+the superblock. Omit by default printing superblocks that are likely
+found in located in an ext3 journal unless an explicit -j option is
+given.
+
+Updated Spanish, French and Dutch translations and added Catalan
+translation. (Addresses Debian bug: #411562)
+
+Use FreeBSD's DIOCGMEDIASIZE and DIOCGDINFO ioctls if available when
+determining a partition's size, since binary searching to determine
+the device doesn't work on FreeBSD.
+
+Documentation about UUID's is available in enough places, and it's
+awkward to deal with debian-legal's insanities. So I'm caving in the
+"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we
+don't have do the dfsg tarball. Also remove the rule that only tried
+to install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
+e2fsprogs exclusively from Debian. (Addresses Debian Bug: #407107)
+
+Fix the info-dir line so that the menu name does not contain a .info
+prefix. First of all, it's ugly, secondly, it causes the install-info
+command to fail to remove the com_err info file from the
+/usr/share/info/dir file when the comerr-dev package is removed and
+purged. (Addresses Debian Bug: #401711)
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+(Addresses Debian Bug: #369761, #373004, #379695)
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs #389554, #390664, #413208, #419605,
+#408352, #415560, #399155)
+
+
+Programmer's notes:
+-------------------
+
+E2fsck now supports the %It expansion when printing a problem report.
+It will print the type of the inode in the problem context.
+
+Fix misc/Makefile.in so that it builds even if e2fsck hasn't been built yet
+(Addresses Sourceforge Bug: #1565561)
+
+Remove unused variables and other lint/gcc -Wall cleanups
+
+Add check to ext2fs_get_device_size() so it will return EFBIG for for
+filesystems contained in regular files where the filesystem image size
+is returned by stat64().
+
+Set local environment variables to C so mk_cmds and compile_et always
+work. (Addresses SourceForge Bug: #1532177)
+
+Added the 64-bit byte swapping function ext2fs_swab64().
+
+Added two new helper functions to prevent 2**31/2**32-1 overflow
+problems: ext2fs_div_ceil() and e2p_percent().
+
+Create new ext2fs library inline functions ext2fs_group_first_block()
+and ext2fs_group_last_block() in order to calculate the starting and
+ending blocks in a block group.
+
+Create the generated files read-only to remind developers not to edit them.
+
+Add support for autoconf 2.60 (with backwards compatibility for older
+versions of autoconf).
+
+Added an "make rpm" target to top-level Makefile
+
+Added various FreeBSD portability fixes.
+
+Exclude mercurial files from the RPM build tree to speed up copy/build.
+
+Use root_sysconfdir to define the locations of mke2fs.conf and
+e2fsck.conf instead of using a hard-coded /etc pathname.
+
+Prevent e2fsck.h and ext2_ext_attr.h from getting included multiple times.
+
+Fixed "make clean" in blkid's Makefile.in file from removing tst_*.c files.
+
+If diff -u is supported, use it to report test failures.
+
+Updates/improvements to RPM spec file
+
+Add on-disk format definitions for the following new features:
+EXT4_FEATURE_RO_COMPAT_HUGE_FILE, EXT4_FEATURE_RO_COMPAT_GDT_CSUM,
+EXT4_FEATURE_RO_COMPAT_DIR_NLINK, EXT4_FEATURE_INCOMPAT_64BIT,
+EXT4_FEATURE_RO_COMPAT_EXTRA_ISIZE
+
+Add a new make target "checked-failed" in the tests directory which
+reruns any failed tests
+
+Update draft-leach-uuids-guids-01.txt with rfc4122.txt
+
+Fix miscellaneous bugs reported by Coverity: Dead code, potential nul
+pointer dereferences, memory leaks, etc. None were security-criticial
+problems.
+
+Fix up usage and decrement error messages in the test_icount program
+
+Add debugging code to the com_err library; if the environment variable
+COMERR_DEBUG is set to 1, print out debugging messages as error tables
+are added and removed from the com_err library. If the
+COMERR_DEBUG_FILE environment variable is set (and the process is not
+setuid) the debugging messages may be redirected to a file.
+
+Change all of the e2fsprogs programs to use the newer add_error_table()
+and remove_error_table() interfaces instead of the much older
+initialize_*_error_table() function.
+
+Add TDB support into the ext2fs library. This allows us to have a
+guaranteed library we can count on always being present so we can
+store data in an on-disk database.
+
+Add support for using TDB to store the icount data, so we don't run out
+of memory when checking really large filesystems.
+
+Change the regression test suite so that it skips empty test directories.
+
+Define the l_i_iversion field in ext2_inode. The l_i_version field is
+now defined from the old l_i_reserved1 field in the ext2 inode. This
+field will be used to store high 32 bits of the 64-bit inode version
+number.
+
+Add Makefile production rule for e2fsprogs.spec in case it gets
+deleted.
+
+Add new function profile_get_uint() to allow for a clean way to fetch
+unsigned integers from the context.
+
+Add test to make sure the ext2 superblock structure is 1024 bytes.
+
+Fix typo in name of f_dup4 regression test
+
+Add new function blkid_gc_cache() which performs a garbage collection
+pass on the /etc/blkid.tab file.
+
+The ext2fs_open() function now sets EXT2_FLAG_MASTER_SB_ONLY. In
+general, only e2fsck (after the filesystem is clean), tune2fs, and
+resize2fs should change the backup superblocks by default. Most
+callers of ext2fs_open() should not be touching any superblock fields
+which require the backups to be touched.
+
+Add new function to libext2fs, ext2fs_default_journal_size(), which
+returns the default journal size.
+
+
+E2fsprogs 1.39 (May 29, 2006)
+=============================
+
+Fix 32-bit cleanliness in e2fsprogs so that we can support filesystems
+between 2**31 and 2**32 blocks.
+
+Change mke2fs to use /etc/mke2fs.conf as a configuration file to
+configure the filesystem features, blocksize, and inode_ratio for
+different filesystem types.
+
+Mke2fs will now create filesystems hash trees and on-line resizing
+enabled by default, based on the new /etc/mke2fs.conf file.
+
+The e2fsprogs tools (resize2fs, e2fsck, mke2fs) will open the
+filesystem device node in exclusive mode to prevent accidents by
+system administrators. In the case of resize2fs and mke2fs, it will
+only use exclusive mode if the filesystem is not mounted.
+
+Fixed a bug in mke2fs which caused it to to fail when creating the
+resize inode for large filesystems. (Addresses Debian Bug #346580)
+
+When allocating space for the RAID filesystems with the stride
+parameter, mke2fs will now place each portion of the group's inode
+table right up after the superblock (if present) in order to minimize
+fragmentation of the freespace.
+
+Speed up mke2fs and e2fsck by writing inode and block bitmaps more
+efficiently by writing the inode and block bitmaps in one pass, thus
+reducing the number of disk seeks required.
+
+Add support for on-line resizing to resize2fs.
+
+Fix blkid library so that logic to determine whether or not a device's
+cached information in /etc/blkid.tab needs to be verified or not
+doesn't get confused by a system clock which is insane (for example,
+if the battery is dead on a Macintosh running PPC Linux. (Addresses
+Red Hat Bug: #182188)
+
+The blkid library will now store the UUID of the external journal used
+by ext3 filesystems, so that in the future, the userspace mount binary
+can use this to find the location of the external journal and pass
+this information to the kernel.
+
+E2fsck will now consult a configuration file, /etc/e2fsck.conf to
+control how various options should be handled. See the e2fsck.conf
+man page for more details. (Addresses Debian Bug: #150295)
+
+E2fsck now prints an explanatory message when delaying a filesystem
+check when the system is running on battery. (Addresses Debian Bug:
+#350306)
+
+E2fsck will detect if the superblock's last mount field or last write
+field is in the future, and offer to fix if so. (Addresses Debian Bug
+#327580) These problems will be fixed automatically in preen mode
+since Debian's boot sequence bogusly doesn't set the time correctly
+until potentially very late in the bootup process, and this can cause
+false positives which will cause users' systems to fail to boot.
+(Addresses Debian Bugs #343662 and #343645)
+
+E2fsck now checks to see if the superblock hint for the location of
+the external journal is incorrect, and if so, offer to update it.
+(Addresses Debian Bug: #355644)
+
+Fix e2fsck from segfaulting on disconnected inodes that contain one or
+more extended attributes. (Addresses Debian Bug: #316736, #318463)
+
+E2fsck will stop and print a warning if the user tries running a
+read/write badblocks test on a read-only mounted root filesystem.
+
+Fix a memory leak in e2fsck's error paths. (Thanks to Michael
+C. Thompson for pointing these out; they were originally found using
+Coverity.)
+
+When resizing a file containing a filesystem, resize2fs will expand or
+truncate a file as necessary. (Addresses Debian Bug: #271607)
+
+Resize2fs will now automatically determine the RAID stride parameter that
+had been used to create the filesystem, and use that for newly created
+block groups. The RAID stride parameter may also be manually specified
+on the command line using the new -S option to resize2fs.
+
+Fix mke2fs so that it correctly creates external journals on
+big-endian machines (such as a S/390).
+
+Fix a bug in the e2p library which could cause dumpe2fs to (rarely)
+fail to print out the journal or hash seed UUID. (Thanks to Guillaume
+Chambraud for pointing this out.)
+
+Dumpe2fs will now print the size of the journal (if present).
+
+Fix debugfs's set_inode_field command so it can properly set the frag,
+fsize, uid_high, gid_high, and author fields in the inode instead of
+silently failing, and so that setting the i_size actually sets i_size
+correctly.
+
+Add a new debugfs command, set_current_time, which sets fs->now so
+that regression test suites can repeatedly modify the filesystem's
+last_write fields.
+
+Fix a bug in debugfs's icheck which would incorrectly report the owner
+of an extended attribute block.
+
+Fix the debugfs commands htree_dump, dx_hash, and list_dir so they print a
+print a usage message when an illegal option character is given.
+
+Fix debugfs's dump_unsued command on filesystems with a 64k blocksize
+so it won't core dump. (Addresses SourceForge bug #1424311)
+
+Fix mklost+found so that it creates a full-sized directory on
+filesystems with larger block sizes.
+
+Fix a file descriptor leak in blkid library.
+
+Fix a display bug in "badblocks -sv" so that the done message properly
+clears the block number at the end of the test. (Addresses Debian Bug
+#322231)
+
+Allow fractional percentages to the -m option in mke2fs and tune2fs
+(Addresses Debian Bug: #80205)
+
+Use fstat/fstat64 in getsize.c if the the target is a regular file,
+instead of attempting to do a binary search. Fix some fd leaks in
+error cases.
+
+Add support for device mapper library to the blkid library to ensure
+that the "best" (i.e., leaf) device is probed by the blkid library.
+
+Fix the blkid library so that it notices when an ext2 filesystem is
+upgraded to ext3.
+
+Improve the blkid's library VFAT/FAT detection; it now understands
+labels stored in the root directory, and is more paranoid about
+checking the FAT superblock values.
+
+Fixed a fd leak in the uuid library which was causing problems for the
+LVM tools. (Addresses Debian Bug: #345832)
+
+Add support for the reiser4 and software suspend partitions to the
+blkid library. Also add support for extract the label from iso9660
+filesystems.
+
+Fix a compile_et bug which miscount the number of error messages if
+continuations are used in the .et file.
+
+Add extra sanity checks to protect users from unusual cirucmstances
+where /etc/mtab may not be sane, by checking to see if the device is
+reported busy (works on Linux 2.6) kernels. (Addresses Debian Bug
+#319002)
+
+Updated French, Dutch, Polish, and Swedish translations. (Addresses Debian
+Bug: #343149, #341911, #300871, #316604, #316782, #330789)
+
+Fix use-after-free bug in e2fsck when finishing up the use of the
+e2fsck context structure.
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages and
+documentation. (Addresses Debian Bugs: #329859, #322188, #316811,

+
+
+Programmer's notes:
+-------------------
+
+Update config.guess and config.sub to latest version (2006-02-23) from
+FSF.
+
+Fix asm_types.h type conflicts on AMD 64 platforms. (Addresses Debian
+Bugs: #360661, #360317)
+
+Fixed the Makefile so that they work correctly on newer versions of
+GNU make (i.e., 3.81).
+
+Add valgrind support to the regression test suites, and eliminate
+false positives from valgrind.
+
+Add a regression test suite for the blkid library.
+
+Fix a fencepost error in resize2fs caught by valgrind.
+
+Fix compiler warnings about missing memcpy prototypes.
+
+We no longer have the sparc assembly code in the header file any more,
+so we shouldn't set _EXT2_HAVE_HAS_BITOPS_ for the sparc. This would
+break compiles on the sparc architectures when using gcc.
+
+In the libext2fs library, add the new field fs->now which if non-zero
+is used instead of the system time when setting various filesystem
+fields (last modified time, last write time, etc.)
+
+Fix gcc 4.01 complaints by adding a missing #include <string.h> to
+ext2fs.h which is needed since the inline functions use memcpy().
+(Addresses Sourceforge Bug #1251062)
+
+Use BUILD_CFLAGS and BUILD_LDFLAGS instead of CFLAGS and LDFLAGS in
+the build system when building files in the util directory which are
+needed during the build process. This avoids potential problems when
+cross-compiling and some of the options specified in CFLAGS or LDFLAGS
+are not recognized as valid by the host compiler. (Addresses
+Sourceforge Bug #1261547)
+
+Clean up the blkid library by making the superblock and generic i/o
+functions to be more generic. Clean up interface to the probe
+function, and fix memory leak. Finallly, remove an unneeded reference
+to probe.h in the lib/blkid/resolve.c
+
+Add an ext2fs_read_bb_FILE regression test to confirm proper detection
+of invalid block #'s.
+
+The x86 asm constraints for ext2fs_{set/clear}_bit have been fixed to
+indicate that the the function read/writes the memory location.
+
+Fix various gcc -Wall complaints.
+
+Add a dependency to make sure that the subdirectories are created
+before creating all of the object files, in order to address parallel
+build problem in the library Makefiles. (Addresses Sourceforge Bug:
+#1261553)
+
+Add $(LDFLAGS) to the command line argument when generating an ELF or
+Solaris shared library, to allow cross-compile and other builds that
+might need to specify -L paths to needed libraries. (Addresses
+Sourceforge Bug #1261549)
+
+Add a new feature, EXT2_FEATURE_COMPAT_LAZY_BG, which is initially
+intended for testing purposes. It allows an ext2/ext3 developer to
+create very large filesystems using sparse files where most of the
+block groups are not initialized and so do not require much disk
+space. Eventually it could be used as a way of speeding up mke2fs and
+e2fsck for large filesystem, but that would be best done by adding an
+RO_COMPAT extension to the filesystem to allow the inode table to be
+lazily initialized on a per-block basis, instead of being entirely
+initialized or entirely unused on a per-blockgroup basis.
+
+Fix backwards compatibility so e2fsprogs will better compile on Linux
+2.0.35 systems.
+
+Make test scripts more robust against locale-related environment variables
+
+Fix type warning problem with sizeof() in ext2fs_open2().
+
+Fix type warning problem with time_t in debugfs.
+
+
+E2fsprogs 1.38 (June 30, 2005)
+==============================
+
+Fix blkid's test programs (built with "make check") compile correctly
+even without "configure --enable-blkid-debug".
+
+Fix ia64 core dump bug caused by e2fsprogs running afoul of C99 strict
+type aliasing rules on newer gcc compilers. (Addresses Red Hat
+Bugzilla ##161183.)
+
+Fix com_err library to make it more compatible with recent changes
+made to the com_err library in MIT Kerberos V5 version 1.4.
+(Addresses Sourcefroge Bug #1150146)
+
+General cleanup of messages printed by e2fsprogs programs for grammar,
+consistency, and to make life easier for translators. Fixed a few
+strings containing English that had not been marked as needing
+translations. Removed strings that do not need to be translated, to
+make life easier for translators.
+
+Mke2fs and badblocks will take advantage of a feature in Linux 2.6 to
+test to see if a device appears to be in use instead of just relying
+on /proc/mounts and /etc/mtab. (Addresses Debian Bug #308594).
+
+Fix portability problem in the filefrag program affecting platforms
+where the size of an integer is smaller than the size of a long.
+(Addresses Debian Bug #309655)
+
+Mke2fs will now use a larger journal by default for filesystems
+greater than 4GB. (128 MB instead of 32MB).
+
+Mke2fs will refuse to create filesystems greater than 2**31-1 blocks,
+unless forced. This is to avoid signed vs. unsigned kernel bugs in
+block numbers that still need to be fixed.
+
+The blkid program has a new option which will more efficiently search
+for device when it is known (or expected) that only one matching
+device will be found in the system, such as when doing a lookup by
+UUID.
+
+Debian's e2fsprogs-specific initrd fragment will avoid including
+unnecessary libraries into the initrd ramdisk by unsetting LD_PRELOAD
+and LD_LIBRARY_PATH, and filtering out libraries found in
+/etc/ld.so.preload. (Addresses Debian Bug: #304003)
+
+Fixed a potential portability issue in the blkid programs for
+architectures where the char type is unsigned. (Addresses Sourceforge
+Bug: #1180585)
+
+Fix a bug in filefrag so that it doesn't falsely count an extra
+discontinuity when the first block found is an indirect block.
+(Addresses Debian Bug #307607).
+
+Fix blkid's recognition of cramfs filesystems, and enhance it to be
+able to handle cramfs labels.
+
+Fix debugfs's stat command to not core dump when a filesystem is not
+open.
+
+Fix e2fsck's handling of error conditions caused by the resize inode
+claiming blocks that are also used by other inodes, a filesystem
+corruption which was commonly caused by a bug in Fedora Core 3's
+resize2fs program.
+
+Fixed bug in filefrag which caused it to fail on non-ext2/3
+filesystems. (Addresses Debian Bug: #303509)
+
+If the superblock last mount time indicates that the system clock may
+not be accurate, then e2fsck will omit checking inodes' deletion time
+field for indications of a potential corrupted orphaned inode list.
+(Previously e2fsck only ommited these LOW_DTIME checks when the
+superblock's last write time looked insane.)
+
+Fixed a IA64 core dump bug in the e2p library which affected dumpe2fs.
+(Addresses Debian bug #302200)
+
+Make the blkid library more paranoid about being run from setgid
+programs, and to use __secure_getenv() from libc if it is available.
+
+Fixed spelling mistakes, typos, and otherwise clarified man pages.
+(Addresses Debian Bugs: #304591, #304592, #304594, #304597, #304593
+and Sourceforge Bug: #1189803)
+
+Updated and fixed translations.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details.
+
+Programmer's notes:
+-------------------
+
+Ext2fs_set_bit(), ext2fs_clear_bit(), and ext2fs_test_bit( have been
+changed to take an unsigned int for the bit number. Negative bit
+numbers were never allowed (and didn't make any sense), so this should
+be a safe change. This is needed to allow safe use of block numbers
+greater than or equal to 2**31.
+
+The compile_et program will avoid recreating generated foo_err.c and
+foo_err.h files if no changes are necessary. The compile_et program
+will also atomically replace these files to avoid a potential parallel
+build race problem on SMP systems. (Addresses Sourceforge Bug:
+#1157933)
+
+Added a new function to the blkid library, blkid_probe_all_new(),
+which only probes newly added disk devices, and change
+blkid_find_dev_with_tag() to use this function so that when a
+requested tag is not found, devices that were previously not checked
+are searched before searching all devices in the system.
+
+Added new functions to the blkid library, blkid_dev_set_search() and
+blkid_dev_has_tag().
+
+E2fsck's problem strings can now use @m and @n as abbrevations for
+"multiply-claimed" and "invalid", respectively.
+
+The e2fsprog.pot file now has an explanation of how the @-expansion
+and %-expansion works, and strings in e2fsck/problem.c which contain @
+characters now have comments in e2fsprogs.pot with the @-expansion to
+make life easier for translators.
+
+Fixed missing return values in the ext2fs library which could cause it
+to return random garbage in certain error conditions.
+
+Allow the current time to be overriden via the E2FSCK_TIME environment
+variable for use in regression tests.
+
+The test scrpit driver program now exits with a non-zero status if
+there any of its test that it ran failed.
+
+Fixed problems with parabuilds on SMP systems. (Addresses Sourceforge
+Bug: #1157933)
+
+Fixed "make check" so that it compiles correctly even when e2fsprogs'
+header files have not be installed in the system include directories.
+(Addresses Sourceforge Bug: #1180572)
+
+Fixed gcc -Wall nits.
+
+
+E2fsprogs 1.37 (March 21, 2005)
+===============================
+
+Add support for checking the validity of Extended Attributes stored in
+inodes to e2fsck.
+
+Add support for dumping the contents of large inodes to debugfs,
+including the extended attributes stored in inodes.
+
+Fix mke2fs, e2fsck, debugfs, and the ext2fs_mkdir function so that
+when we create a new inode we make sure that the extra information in
+the inode (any extra fields in a large inode and any ea-in-inode
+information) is initialized correctly. This can take place when
+mke2fs creates the root and lost+found directory, when e2fsck creates
+a new root inode or a new lost+found directory, and when the user uses
+the debugfs write, mknod, or mkdir commands. Otherwise, the newly
+create inode could inherit garbage (or old EA information) from a
+previously deleted inode.
+
+Fixed a bug in e2fsck so it would notice if a file with an extended
+attribute block was exactly 2**32 blocks, such that i_blocks wrapped
+to zero.
+
+Added support to filefrag to detect files which are using the new
+experimental file extents format, and use the non-ext2 algorithm in
+that case. Fixed a bug to avoid reporting a false discontinuity if
+there is one or more unallocated blocks at the beginning of a file.
+
+Duplicated a check for noticing whether or not the number of blocks
+(given a certain blocksize) is greater than 2**32 when the
+BLKGETSIZE64 ioctl is not available to ext2fs_get_device_size(). This
+allows mke2fs to automatically use a larger blocksize when creating a
+filesystem on a very large device when run on systems that do not
+support BLKGETSIZE64.
+
+Fix the I18N build which was broken in e2fsprogs 1.36 because the
+build system had been switched to treat the .gmo files as shipped
+files (for backwards compatibility with systems that have older GNU
+I18N tools installed), but the gen_tarball.in script was still
+removing the .gmo files from the official source distribution.
+
+Fixed various Debian packaging issues --- see debian/changelog for
+details. (Addresses Debian Bugs ##296769, #299341)
+
+Programmer's notes:
+-------------------
+
+Added new functions to the e2p library which convert between a string
+and os_type: e2p_os2string() and e2p_string2os(), and used them to
+make the generated binaries more compact.
+
+Fixed a compile-time error on Darwin systems.
+
+Cleaned up the lib/ext2fs Makefile slightly.
+
+
+E2fsprogs 1.36 (February 4, 2005)
+=================================
+
+All of the patches that were applied to Fedore Core 3's
+e2fsprogs-1.35-11.2 have been integrated, although sometimes with a
+lot of bug fixes first. Users of Fedora Core 3 are strongly
+encouraged to upgrade to e2fsprogs 1.36 as soon as possible.
+
+Add support for filesystem with the online resizing via resize inode
+feature. Fixed numerous bugs from the Fedora patches. The Fedora
+patches also didn't bother to do any consistency checking on the
+resize inode, or add any tests to the regression test suite. The "-R
+resize=4g" option to mke2fs was a no-op in the Fedora patches, despite
+being listed in mke2fs's usage message. All of these shortcomings
+have been corrected.
+
+E2fsck can also also fix filesystems trashed by Fedora's resize2fs
+program. In order to do this, the user must run the commands:
+
+ debugfs -w /dev/hdXXX -R "features ^resize_inode"
+ e2fsck -f /dev/hdXXX
+
+Optionally, the ext2prepare command can be used to re-enable online
+resizing after the filesystem has been fixed.
+
+The fsck program will now accept an optional filedescriptor argument
+to the -C option. (The Fedora version of this patch would sometimes
+cause fsck to ignore a parameter on fsck's command line in some rare
+cases, sigh.)
+
+Make sure e2fsprogs doesn't write garbage into the reserved portion of
+large inodes.
+
+Make sure resize2fs releases the blocks belonging to the old inode
+table blocks when moving the inode table. (Addresses Debian Bug:
+#290894)
+
+Skip the r_resize_inode test if resize2fs is not compiled (due to
+configure --disable-resizer)
+
+E2fsck now checks the summary filesystem accounting information, and
+if any of the information is obviously wrong, it will force a full
+filesystem check. (Addresses Debian Bug #291571)
+
+Fix e2fsck to not complain when the resize_inode feature is enabled,
+s_reserved_gdt_blocks is zero, and there is no DIND block allocated in
+the resize inode.
+
+Fix e2fsck to note delete symlinks that contain an extended attribute
+after the ext_attr feature flag has been cleared. (Addresses Red Hat
+Bugzilla #146284).
+
+Add new utility program, copy_sparse.c, which is very useful
+for dealing with large sparse files (such as e2image files).
+
+Add support for jnl_blocks[] for debugfs's set_super_value.
+
+Fix filefrag so that it works correctly with sparse files.
+
+Filefrag -v will print first and last blocks.
+
+Add interpretation of OS Creator values for FreeBSD and Lites in mke2fs
+and dumpe2fs.
+
+Add mke2fs support so that it can support filesystems larger than 4TB
+automatically, by retrying with a 4k blocksize if the device size is
+too big to be expressed using a 1k blocksize. (Addresses Sourceforge
+bug #1106631)
+
+Change blkid to test for NTFS first because Windows sometimes doesn't
+clear enough of the parition to confuse the probing routines into
+thinking the old filesystem type is still valid. (Addresses Debian
+Bug #291990)
+
+Add support for swap partition label and uuid's in the blkid library.
+
+Add support to the blkid library to recognize Oracle ASM volumes.
+
+Make blkid -t display all devices that match the specified criteria,
+not just the first one, and work more consistently when the blkid
+cache file is not available or set to /dev/null. (Addresses Debian
+Bug #290530 and #292425)
+
+Badblocks will now correctly display block numbers greater than
+999,999,999 in its progress display.
+
+The tune2fs program will not allow the user from setting a ridiculous
+number of reserved blocks which would cause e2fsck to assume the
+superblock was corrupt. E2fsck's standards for what is a ridiculous
+number of reserved block has also been relaxed to 50% of the blocks in
+the filesystem.
+
+The blkid library will return vfat in preference to msdos, and ext3 in
+preference to ext2 (if the journalling flag is set) so that mount will
+do the right thing. (Addresses Debian bug #287455)
+
+Mke2fs will now use the -E option for extended options; the old -R
+(raid options) option is still accepted for backwards compatibility.
+Fix a double-free problem in resize2fs. (Red Hat Bugzilla #132707)
+
+Mke2fs will now accept a size in megabytes, gigabytes, and other units
+(via "32m" or "4g" on the command line) if the user finds this more
+convenient than specifying a block count.
+
+Fix an obscure, hard-to find bug in "e2fsck -S" caused by an inode
+cache conherency problem.
+
+Debugfs now supports a new command, set_inode_field, which allows a
+user to manually set a specific inode field more conveniently, as well
+as set entries in the indirect block map.
+
+Debugfs's set_super_value command has been enhanced so that the user
+can set most superblock fields, including the date/time fields and
+some of the more newsly added superblock fields.
+
+E2fsprogs programs now accept an offset to be passed to the file
+specifiers, via the syntax: "/tmp/test.img?offset=1024".
+
+E2fsprogs programs will now accept blocksizes up to 65536; kernel
+support on the x86 doesn't exist for now, but it can be useful on
+other architectures with page sizes greater than 4k. There are 2.6
+kernel patches out there which enable this, but they are of this
+writing still experimental.
+
+The e2image command now takes the -s option which will scramble
+directory entries for raw image files.
+
+Fix a file descriptor leak in the filefrag program.
+
+Make sure e2fsck doesn't crash when /proc/acpi/ac_adapter is not
+present.
+
+Fix bug in debugfs where kill_file would lead to errors when deleting
+devices and symlinks. (Sourceforge Bugs #954741 and #957244)
+
+Fix bug in the blkid library when detecting the ocfs1 filesystem
+
+Remove obsolete EVMS 1.x and a.out DLL support.
+
+E2fsck will attempt to recover from a journal containing illegal blocks.
+
+Fixed two potential ordering constraint problems in e2fsck which might
+cause the filesystem to be corrupted if e2fsck is interrupted during a
+(extremely narrow) race window. Thanks to Junfeng Yang from the
+Stanford Metacompilation group for pointing this out.
+
+Fixed bug in e2fsck where it would not accurately detect whether or
+not the system is running on adaptor if the ACPI device representing
+the AC adapter didn't correspond to the what was used on IBM
+Thinkpads.
+
+Change e2fsck to accept directories greater than 32MB.
+
+Fix e2fsck so that a checkinterval of zero disables a time-based check
+of the filesystem.
+
+Debugfs will check the DEBUGFS_PAGER enviroment variable in preference
+to the PAGER environment variable. (Addresses Debian Bug #239547)
+
+Tune2fs will not mark rewrite the superblock if the feature bitmasks
+are not modified.
+
+The debugfs program will set the filetype information when creating a
+link.
+
+Add debugfs -d option to use a separate source of data blocks when
+reading from an e2image file.
+
+Add e2image -I option which allows the e2image metadata to be
+installed into a filesystem.
+
+Fixed bug in the badblocks program which caused "done" to always
+appear in english even when a translation was available. (Addresses
+Debian Bug #252836)
+
+The blkid program has a new option -o which controls the output format
+of the blkid program; this is makes blkid more convenient to use in
+shell scripts.
+
+Fix a minor bug in uuid library, which was not using the full 14 bits
+of clock sequence when generating UUID's.
+
+Fix a Y8.8888K problem in the uuid library.
+
+Logsave now creates a new session id for itself to avoid getting
+killed by init whan transitioning between init levels.
+
+Change the licensing of the UUID library to be the 3-clause BSD-style
+license; this allows Apple to use the uuid library in Darwin.
+
+Add ocfs and ocfs2 probe support into the blkid library.
+
+Fix a memory and file descriptor leak in the blkid library.
+
+The blkid library will revalidate the device if the system time is
+earlier than last verification time of the device, since that
+indicates that the system time is probably nottrustworthy.
+
+The blkid library will override the default location of the blkid.tab
+file by the BLKID_FILE environment variable, if it is available.
+
+Change the getsize functions to use the BLKGETSIZE64 ioctl on Linux 2.6.
+
+Add various portability fixes for lame new versions of glibc, Darwin
+and GNU/KFreeBSD, as well as removing XSI:ism's. (Addresses Debian
+Bugs #239934, #264630, #269044, #255589, #289133)
+
+Add support for Windows 9x/NT under Cygwin.
+
+Updated and clarified various man pages. (Addresses Debian Bugs #236383,
+ #241940, #238741, #242995, #256669, #268148, #256760, #273679)
+
+Updated and fixed translations. (Addresses Debian bugs #244105, #262836)
+
+Update the rpm spec files so that it works better with Fedora core 2
+and RH9.
+
+Fixed various Debian packaging issues (see debian/changelog). In
+particular, fixed the Debian initrd scripts. (#241183, #248050,
+#253595, #247775)
+
+
+Programmer's notes:
+-------------------
+
+Fixed various gcc -Wall warnings.
+
+The uuid library now has new functions uuid_unparse_upper() and
+uuid_unparse_lower() which forces the case of the hex digits to be
+upper case, or lower case.
+
+The build process has been speeded up by enhancing the subst program
+to update the modtime on the generated files even when the generated
+file hasn't changed.
+
+The uuid library now uses C99 stdint.h types instead of custom types.
+
+Updated config.guess and config.sub with newer versions from the FSF.
+
+Removed out of date .cvsignore files from the source distribution.
+
+The ext2fs_unlink() function will return an error if both the name and
+inode number are unspecified, to avoid doing something surprising
+(such as unconditionally deleting the first directory entry).
+Directory entries are now deleted by coalescing them with the previous
+directory entry if possible, to avoid directory fragmentation. This
+is not an issue with the e2fsprogs suite, but may be a problem for
+some of the users of libext2fs, such as e2tools.
+
+Add support for version numbers of the form "1.36-rc1".
+
+Fix build of mke2fs.static.
+
+Add basic ext2fs library support for large (EA in inode) inodes.
+
+The test_io mechanism can now abort after n reads or writes to a
+particular block. The block is specified by TEST_IO_BLOCK environment
+variable, and the read/write count by the TEST_IO_READ_ABORT and
+TEST_IO_WRITE_ABORT environment variables. The block data is now only
+dumped if the 0x10 bit is set in TEST_IO_FLAGS.
+
+UUID_DEFINE() in the uuid library now creates a static variable, with
+__attribute__ ((unused)) if we are using GCC, so that UUID_DEFINE can
+be used in header files.
+
+Add support for the install-strip and install-shlibs-strip targets, as
+suggested by the GNU coding guielines. "make install" no longer
+strips the binaries which are installed.
+
+Remove support for the --enable-old-bitops configure option which was
+only for very old sparc systems.
+
+Remove support for --enable-clear-htree; this was only needed during
+the early development of the htree patch.
+
+Use Linux-kernel-style makefile output so it is easier to see compiler
+warnings.
+
+Update gettext files to version 0.14.1.
+
+Update to use autoconf 2.5x.
+
+Improved support for compiling e2fsprogs under dietlibc.
+
+Make e2fsprogs portable to Solaris and FreeBSD systems.
+
+Add blkid_verify(), blkid_get_library_version(), and
+blkid_parse_version_string() functions to the blkid library.
+
+Add pkg-config files for e2fsprogs's libraries.
+
+Fix "make uninstall" to so that it removes everything that is installed.
+
+Add a configure --enable-maintainer-mode option which enables the
+makefile rules to rebuild the configure script from configure.in, and
+to reubuild the .gmo files in po directory.
+
+Drop the sparc assembly bitwise operations; it's less efficient
+than the GCC 3.4 compile code and triggers compiler warnings on
+sparc64. Thanks to Matthias Andree for his analysis and suggestions.

+
+
+E2fsprogs 1.35 (February 28, 2004)
+==================================
+
+E2fsck has a new -k option, which in conjunction with the -c options,
+preserves the existing badblocks list.
+
+Cleaned up e2fsck's preen-mode messages during the passes 1b, 1c, and 1d.
+
+E2fsprogs will now deal correctly with symlinks that contain
+extended attribute information, which can be created using SE Linux.
+(Addresses Debian Bug #232328)
+
+Remove a double longjump into an invalid stack frame bug in e2fsck.
+(This was during an abort sequence, which normally worked on Linux and
+caused a core dump on other operating systems.)
+
+Fix NLS bug in e2fsck, by avoiding trying to expand an empty string
+(the NLS library will replace "" with the .po header information).
+
+Fix a bug in mke2fs which caused -T largefile or -T largefile4 to core
+dump due to a division by zero error. (Addresses Debian bug #207082)
+
+Fixed a bug in e2fsck which caused it to incorrectly fix a filesystem
+when reconnecting a directory requires creating a lost+found
+directory. (Addresses Debian bug #219640).
+
+Fixed a bug where e2fsck would bomb out if a journal needed to be
+replayed when using an alternate superblock.
+
+E2fsck will give an extra grace period before actually forcing a check
+if the laptop is running on battery. The next time fsck runs while
+the system is on the AC mains, or after the grace period is exceeded,
+the filesystem will be checked. (Addresses Debian bug #205177)
+
+E2fsck will inform the user when there are 5 or fewer mounts before a
+filesystem check will be forced. (Addresses Debian bug #157194)
+
+Fix e2fsck's handling of corrupted indirect blocks in the bad block.
+We now correctly handle the case where there is an overlap between a
+block group descriptor or a superblock and a bad block indirect block.
+In the case where the indirect block is corrupted, we now suggest
+"e2fsck -c".
+
+Fix byte swap bugs in e2fsck that caused the journal backup location
+in the superblock and symlinks created by SE Linux to be cleared
+by e2fsck on big-endian machines. (Addresses Debian bug #228723)
+
+E2fsck -c now replaces the current list of bad blocks with the ones
+found by badblocks.
+
+Fix bugs in e2fsck and tune2fs which could cause a core dump if a
+non-existent LABEL or UUID specifier is to e2fsck or tune2fs.
+
+Fix a potential bug in e2fsck which could cause it to core dump when
+trying to print the location of the backup superblock.
+
+Protect against a potential core dump in e2fsck when printing a
+message about backup superblocks.
+
+Add support for backing up the journal inode location in the
+superblock. E2fsck will automatically save the journal information in
+the superblock if it is not there already, and will use it if the
+journal inode appears to be corrupted. ext2fs_add_journal_inode()
+will also save the backup information, so that new filesystems created
+by mke2fs and filesystems that have journals added via tune2fs will
+also have journal location written to the superblock as well.
+Debugfs's logdump command has been enhanced so that it can use the
+journal information in the superblock.
+
+E2fsck will now update all superblocks when moving the journal inode.
+
+Shrink the size of the e2fsck executable by moving some initialized
+variables to the BSS segment.
+
+E2fsck will avoid printing the ^A and ^B characters which bracket the
+progress bar when stdout and stdin are a tty device instead of a pipe
+to another program. (Addresses Debian bug #204137)
+
+Debugfs's mkdir command will automatically expand the directory if
+necessary. (Addresses Debian Bug: #217892)
+
+Fixed a bug in debugfs so that copying a file from /dev/null uses the
+correct mode bits. (Addresses Debian Bug: #217456)
+
+If the environment variables DEBUFS_PAGER and PAGER are not set,
+debugfs now searches for the appropriate pager to use, beginning with
+/usr/bin/pager, and then falling back to 'more' and 'less'.
+(Addresses Debian bug #221977)
+
+Debugfs will now support 2.6 device numbers where the major or minor
+number may be larger than 255. (Addresses Sourceforge bug #865289)
+
+Fix debugging printf in resize2fs. (Addresses Debian Bug #271605)
+
+Chattr now stops processing options when it sees '--'. (Addresses
+Debian bug #225188)
+
+Fix regression tests so they work correctly when e2fsprogs is compiled
+with configure --disable-htree.
+
+Fix bug in uuid library when there is no network card and the library
+is generating a time-based uuid. The random MAC address was not
+correctly generated to be a multicast address.
+
+Add compile_et extensions from Heimdall that were missed the first time
+around.
+
+Fix bug in badblocks when using O_DIRECT; we need to make sure that
+we're reading from an offset which is page aligned. For read-only and
+read-write tests, we try to recover after an error so that we can
+continue reading on page-aligned boundaries. (Addresses Debian Bug
+#203713)
+
+Badblocks now checks 64 blocks at a time instead of 16. (Addresses
+Debian bug #232240)
+
+Updated and clarified various man pages. (Addresses Debian Bug
+#206845, #222606, #214920, #232406)
+
+Updated and fixed translations. (Addresses Debian bugs #200086, #214633)
+
+Fixed various Debian packaging issues (see debian/changelog).
+
+Programmer's notes:
+-------------------
+
+Fixed a build problem so that e2fsprogs would compile with the
+--enable-profile option to configure selected. (Addresses Sourceforge
+bug #811408)
+
+Fixed C++ problems with the ext2fs.h header. (Addresses Red Hat
+Bugzilla Bug #112448)
+
+Centralize code which calculates the location of the superblock
+and block group descriptors so that it is in a single library routine.
+
+Added two new functions, ext2fs_file_open2() and
+ext2fs_inode_io_intern2() which take a pointer to an inode structure.
+
+Fix compile_et to output the correct prototype for
+initialize_xxx_err_table_r() in the header file. (Addresses Debian
+bug #204332)
+
+In the lib/et makefile, make sure com_err.info is deleted on "make clean".
+
+Fix 64-bit warnings in e2fsprogs pass1b by using inttypes.h if
+present. This is for when we try stuffing an int into void * pointer.
+
+Fix type-punning which can cause gcc 3.x to miscompile code by getting
+confused about pointer aliasing. ext2fs_getmem(), ext2fs_free_mem(),
+and ext2fs_resize_mem() all now take a 'void *' instead of a 'void
+**'. The EVMS code uses an ugly union approach since we don't want to
+modify the EVMS interfaces.
+
+Make sure all Makefiles use $(MAKE) rather than hardcoded "make", to
+aid build process on systems can use invoke GNU make as "gmake".
+
+Added regression testing for mke2fs.
+
+Fixed gcc -Wall nitpicks.
+
+Fixed various compiler warnings.
+
+Add portability fixes for FreeBSD and for using fsctl under Darwin to
+support ext2 ioctl's.
+
+
+E2fsprogs 1.34 (July 25, 2003)
+===============================
+
+Fixed a bug introduced in E2fsprogs 1.30 which caused fsck to spin in
+a tight loop while waiting for a child fsck to exit in some cases.
+This burns CPU times which slows down the low-level filesystem check.
+
+Added code to mke2fs to assure that the default block size for a
+filesystem is at least as big as the sector size of the device, if it
+can be determined.
+
+Changed mke2fs and resize2fs to round the default size of a filesystem
+to be an even multiple of the VM pagesize in order to avoid a Linux
+kernel bug introduced when the storage of the buffer cache was moved
+into the page cache.
+
+Mke2fs will warn the user when creating a filesystem with journaling
+and a blocksize greater than 4096. (Addresses Debian bug #193773)
+
+Fixed a bug in resize2fs which caused it to fail on filesystems with a
+non-empty bad block list. Resize2fs now discards any blocks on the
+badblock list which are no longer part of the filesystem as the result
+of a filesystem shrink. (Note: this means that shrinking and then
+enlarging a filesystem is no longer a reversible operation;
+information about bad blocks in the part of the filesystem which is to
+be chopped off will be lost.)
+
+Changed resize2fs so the user can use prefixes to specify the units of
+the new filesystem size (sectors, kilobytes, megabytes, or gigabytes),
+and to make the error and informational messages explicitly display
+the blocksize used by the filesystem, in order to avoid confusion.
+(Addresses Debian bug: #189814)
+
+Added a new debugfs command, dump_unused, which dumps the contents of
+all unused blocks to stdout. (Useful as an emergency try-to-find
+deleted data command.)
+
+Added a new debugfs command, imap, which prints the location of a
+specified inode in the inode table.
+
+Fixed a bug in the badblocks program which caused it to use one bit of
+randomness in its non-destructive read/write test, instead of using a
+full 8 bits of randomness.
+
+Added a new option (-t) to badblocks, which allows the user to control
+the test pattern(s) used when checking a disk.
+
+The blkid probe function now more correctly detects UDF filesystems.
+
+Fixed a bug in the blkid library which caused it to not update its
+cache if a filesystem changes from having a label to not having a
+label.
+
+Fixed a bug in the blkid library wihch could avoid an infinite loop
+in blkid_find_dev_with_tag() if /proc is not mounted and there the
+/etc/blkid.tab file has not yet been created.
+
+Fixed the badblocks program so that the destructive read/write test
+honors the -c option, and to use O_DIRECT when possible to avoid
+thrashing the system block buffer cache.
+
+Fixed various NLS issues.
+ - Added Czech and Swedish translations
+ - Removed testing NYC translation
+ - Fixed NLS support for message abbrevations in e2fsck
+ - Remove de-utf.po, since we shouldn't have two versions using different
+ charset encodings.
+ - Used ngettext() (abbreivated with the macro P_(str1, str2, n)) to
+ simplify the statistics reporting in e2fsck.
+
+Changed configure.in so that its defaults for *BSD systems no longer
+build an fsck wrapper, and not to install in /usr/local by default.
+
+Fixed some minor spelling errors/typo's in e2fsck and the configure
+script.
+
+Fixed various Debian packaging issues (see debian/changelog).
+
+Updated and clarified man pages. (Addresses Debian Bug #195616)
+
+Programmer's notes:
+-------------------
+
+Fix gcc -Wall nitpicks.
+
+Updated gettext implementation used by e2fsprogs to 0.11.5, and enable
+NLS support by default. (Added partial workaround for gettext/Darwin
+incompatibility problems.)
+
+Added full MIT KRB5 and Himdall compaibility support to the com_err
+library and the compile_et program. (Addresses Debian bug #191900)
+
+Added the blkid_known_fstype() function to the blkid library, which
+returns true if it is passed a filesystem type which is recognized by
+the blkid probing functions.
+
+Improved the documentation for the blkid library.
+
+Added the ext2fs_get_device_sectsize() function the the ext2fs library, which
+returns the hardware sector size of a device, if it is available.
+
+Added a dependency in the blkid library's .so file to the uuid
+library, since the former uses the latter. (Addresses Debian bug
+#194094)
+
+Added --with-diet-libc and --disable-evms to the configure script.
+
+Fixed a minor memory leak in the badblocks program.
+
+Fixed a portability problem in tune2fs --- not all systems have strptime().
+
+Fixed a portability problem in debugfs with the use of getopt() more
+than once. Old-style BSD, new-style BSD, and Linux C libraries all do
+things differently.
+
+Add support Windows support to ext2fs_get_device_size().
+
+Added (normally disabled) debugging code to the Unix I/O manager which
+causes it to disable all userspace caching if the NO_IO_CACHE is
+defined.
+
+Changed the test I/O manager so it can always be linked into e2fsck,
+mke2fs, and tune2fs if enabled via --enable-test-io-debug to the
+configure script. The test I/O manager will only print any debugging
+information if the TEST_IO_FLAGS or TEST_IO_BLOCK environment
+variables are set, which specifies which I/O operations are logged and
+a block number to watch, respectively. The log messages are sent to
+stderr by default, unless a filename is specified via the
+TEST_IO_LOGFILE environment variable.
+
+
+E2fsprogs 1.33 (April 21, 2003)
+===============================
+
+Added a new utility program, logsave, which captures the output of a
+command in a log file, even if the containing directory hasn't been
+mounted yet (in which case the it saves the output in memory until it
+can write out the logfile). This is useful for capturing the
+output of fsck during the boot sequence.
+
+Fixed some portability problems that were causing problems under
+the Cygwin32 environment.
+
+Mke2fs now interprets a negative number to the -b option as a minimum
+block size.
+
+Fixed a bug in mke2fs which was incorrectly checking the argument to
+the -g option if the default block size was used. (Addresses Debian
+bug #188319)
+
+Fsck now explicitly ignores tmpfs and devpts, and it will complain if
+it can not find filesystem checkers for jfs, reseirfs, and xfs.
+
+E2fsck now updates the global free block and inode counters from the
+block group specific counters quietly. This is needed for an
+experimental patch which eliminates locking the entire filesystem when
+allocating blocks or inodes; if the filesystem is not unmounted
+cleanly, the global counts may not be accurate.
+
+Imported bug fixes to the EVMS plugin from the EVMS 2.0 tree. (EVMS
+2.0 is not yet supported; this only pulled in the bug fixes: fixed
+possible hangs caused by bugs in calling waitpid, and not setting the
+pipe to non-blocking mode; also fixed a file descriptor leak; made
+sure all functions call log entry/exit functions.)
+
+Badblocks now flushes its output file as bad blocks are discovered.
+
+The uuid library is now more paranoid about assuming the correctness
+of the /dev/random device; it mixes in a stream of bytes from
+random/srandom, just in case.
+
+Update Debian files to reflect the fact that I am now the Debian
+maintainer of e2fsprogs. Other various Debian-specific packaging
+cleanups.
+
+Move the source tarball generation functions from the top-level
+makefile to the util/gen-tarball script.
+
+Updated the Turkish .po translation file.
+
+Added Heimdal and MIT krb5 extensions to the com_err library to make
+it more compatible with com_err libraries from those distributions.
+
+Changed dumpe2fs to always display the superblock fields relating to
+the journalling and/or directory indexing feature even if those
+features are not enabled.
+
+Updated and clarify copyright statement vis-a-vis alpha releases of
+e2fsprogs.
+
+The ss library will now try to dynamically link to the readline
+library and use it if it is present in the system. This means that
+the debugfs program now has line editing and history features. The
+SS_READLINE_PATH environment variable is used to find a readline or
+readline-compatible library.
+
+E2fsck now finds most duplicate filenames (all when rebuilding all
+directories via the -D option) and offers to delete or rename
+duplicate filenames/directory entries. (Addresses Debian Bug #176814).
+
+Fix bug in e2image. When writing out a raw image file, include data
+blocks from symlinks that do not store the symlink within the inode.
+
+Fix bug in resize2fs which incorrectly moved the block and inode
+bitmaps for sparse superblock filesystems and incorrectly marked
+blocks as in use. (Addresses Debian bug #174766)
+
+Added a new shared library, the blkid library, which efficiently
+allows fsck, mke2fs, e2fsck, and tune2fs to be able to look up LABEL
+and UUID filesystem specifiers without needing to search all of the
+devices in the system. Instead, the device is looked up in a cache
+file, and then verified to make sure the blkid cache is correct.
+
+Tune2fs and e2label will accept LABEL=xxx and UID=yyy specifiers for
+the device name, using the blkid library. (Addresses Debian bugs
+#166048, #179671)
+
+Fsck now supports backslash escapes in /etc/fstab so that \040 can be
+used for spaces in device labels.
+
+Removed 32-bit limitations for debugfs's dump command.
+
+If the user specifies a large number of inodes, Mke2fs will
+automatically adjust the number of blocks per group to find a valid
+set of filesystem parameters.
+
+Add workaround to detect broken MD devices where when some of the
+underlying devices are marked read-only, writes to the MD device are
+silently dropped. E2fsck will detect if there is an attempt to run
+the journal twice, and abort with an error if this is the case.
+(Addresses IBM Bugzilla bug #1226)
+
+E2fsck will print an error if more than one of the -p/-a, -n or -y
+options are specified.
+
+E2fsck will fix HTREE corruptions in preen mode, without stopping the
+boot process. This is needed because the 2.4 ext2 filesystem
+accidentally had the INDEX_FL backwards compatibility code removed.
+
+Mke2fs no longer creates filesystems with the dir_index flag set by
+default; the user has to specifically request it.
+
+Update and clarified various man pages. (Addresses Debian bugs
+#173612, #175233, #175113, and #170497, #185945, #188318)
+
+Created man page for the mk_cmds program (from the libss library).
+
+Programmer's notes:
+-------------------
+
+Fix various gcc -Wall nits.
+
+Fixed a lot of portability problems that caused e2fsprogs not to build
+successfully under Solaris and Apple/Darwin.
+
+Fixed a Makefile dependency to allow building e2fsprogs using parallel
+make jobs.
+
+Changes to create a subset distribution which consists only of the
+et, ss, uuid, and blkid libraries. The configure script and top-level
+makefile were changed to support working with a subset distribution.
+
+Removed EXT2_FEATURE_RO_COMPAT_BTREE_DIR mention of since it's not
+actually used, and might people who are looking for
+EXT2_FEATURE_COMPAT_DIR_INDEX, which is in use.
+
+Updated debian files to fix a number of Lintian warnings.
+
+Updated config.guess and config.sub with newer versions from the FSF.
+
+Removed unnecessary libraries from being linked into the fsck, lsattr,
+chattr, and blkid executables.
+
+E2fsprogs 1.32 (Nomvember 9, 2002)
+==================================
+
+Fixed a bug in the Unix I/O routines which caused needless writebacks
+of clean blocks from the unix_io cache (they were erroneously marked
+as being dirty, so they were getting written back to disk before
+getting evicted from the disk cache). This was harmless, but it
+significantly slowed down e2fsck.
+
+Made some other minor optimizations to the Unix I/O routines to save a
+small amount of CPU time.
+
+Updated internationalization files.
+
+
+E2fsprogs 1.31 (Nomvember 8, 2002)
+==================================
+
+Update EVMS ext2fsim plugin with EVMS 1.2. (We still support
+compiling the fsim plugin with EVMS 1.0 and 1.1.) Add better error
+handling for child process that die unexpectly. Add a hack to force
+mkfs to create filesystems that won't cause problems with hardware
+that has 2k or 4k minimum blocksize requirements. Read from child
+processes in non-blocking mode, so that the GUI continues to update.
+
+Fix e2fsck so that it returns the appropriate exit code when the root
+filesystem has been changed, so that system's rc scripts will be told that
+the system needs to be rebooted.
+
+Fix a bug in ext2fs_flush/ext2fs_close; when the MASTER_SB_ONLY flag
+was set, some of the descriptor blocks that should have been written
+out were getting skipped.
+
+Changed e2fsck to force out changes to the backup copies of the
+superblock and block group descriptors when important changes are made
+to those data structures.
+
+Fix a bug where e2fsck could erroneously mark a filesystem as being
+clean if a check of dirty filesystem is interrupted with a ^C. (Bug
+introduced in e2fsprogs 1.28.)
+
+If journal debuging is enabled using --enable-jbd-debug, the debugging
+level is now set via the E2FSCK_JBD_DEBUG environment variable.
+
+If byteswapping support is disabled using configure --disable-swapfs,
+skip the tests which depend on byte-swapping, so that "make check"
+won't bomb out.
+
+Lshattr will now display the indexed directory flag. Also, some of
+the more esoteric compression flags are supressed unless compression
+support has been enabled.
+
+Update man pages.
+
+
+E2fsprogs 1.30 (October 31, 2002)
+=================================
+
+When resizing a filesystem, and inodes need to moved, resize2fs will
+update the inode's ctime field, and the mtime field of the containing
+directories, so that incremental backups using dump/restore will work
+correctly.
+
+In order to avoid spurious errors, e2fsck wil check the last
+superblock write time to determine whether or not it can safely use
+the LOW_DTIME checks to determine if there are inodes on the orphan
+inode linked list that had somehow gotten disconnected. (Addresses
+Sourceforge bug #620980)
+
+Partition in /proc/partitions that being with the string "lvm" are
+considered real partitions even if they do not end with a number.
+
+Fixed a bug in the the uuid generation function, where if /dev/urandom
+is not present, but /dev/random is, and there isn't sufficient
+entropy, the get_random_byte function could spin a loop forever.
+
+E2fsck, mke2fs, etc. will now reliably notice when image files are
+mounted using the loopback interface. (Addresses Sourceforge bug
+#619119)
+
+When flushing buffers (as is done by badblocks, for example) check to
+see if the BLKFLSBUF ioctl succeeds, and if so, avoid using the
+FDFLUSH ioctl which causes the MD device driver which causes confusing
+syslog messages about obselete ioctl messages. (Addresses Sourceforge
+bug #545832).
+
+Debugfs's write command now checks to see if the destination filename
+exists before creating it. (Addresses Sourceforge bug #478195.)
+
+When installing man pages, search for compressed man pages using all
+commonly used compression extensions (i.e., .Z, .gz, .bz2, etc.)
+
+Fixed a bug in fsck where multiple filesystems specified on the
+command were not being checked in parallel due to a logic bug
+introduced to support the FSCK_MAX_INST environment variable.
+
+We have added a new superblock field, s_mkfs_time, which indicates
+when a filesystem was created. It is set via mke2fs, and printed out
+by dumpe2fs, but is not actually touched by the kernel.
+
+Dumpe2fs has been made more robust by not aborting if there is an
+error reading the block/inode bitmaps; instead it will still print out
+the location of the block/inode bitmaps and inode table.
+
+Add support for the an alternative block group descriptor layout which
+allows for on-line resizing without needing to prepare the filesystem
+in advance. (This is the incomat feature flag meta_bg.)
+
+Add support for storing default mount options in the superblock, so
+that the filesystem can be mounted with specific mount options without
+needing to specify them on the mount command line or in the /etc/fstab
+file.
+
+Add support for a new inode flag, which is to be used for indicating
+the top of directory hierarchies for the Orlov block allocator.
+
+Fix e2fsck so that if it creates the lost+found directory, it does so
+with the more apporpriate permissions of 0700. Also change
+mklost+found so that it also creates the directory 0700.
+
+Fixed format bug in e2fsck if NLS is in use.
+
+Add a German translation for e2fsprogs's NLS support.
+
+Fixed e2fsck so that it more handles BAD_BLOCK_IN_INODE_TABLE even at
+the beginning of the inode table. This won't matter much, since if
+there is a bad block at the beginning of the inode table, the root
+directory won't be available. But at least e2fsck won't crash in this
+case.
+
+Fixed endian problems in the htree code for e2fsck and debugfs.
+
+When byte-swapping a filesystem on a PPC architecture, byte-swap the
+bitmaps since the historical big-endian ext2 variant had byte-swapped
+bitmaps, and the ext2fs library assumes this. This fixes the
+regression test suite on PPC machines.
+
+Fix e2image so that it handles a bad block in the inode table
+appropriately.
+
+E2fsck now uses a more sophisticated algorithm to salvage corrupted
+directories that recovers more information in the corrupted directory
+block.
+
+E2fsck now performs additional consistency checks on indexed (HTREE)
+directories.
+
+Fix bug where efsck might get confused about whether a completely
+empty directory block is an empty leaf block or an interior htree
+node. This could cause e2fsck to get confused into think that a valid
+indexed directory was corrupted.
+
+E2fsck no longer creates an empty directory entry at the end of a
+directory block when optimizing a directory. This would cause some
+earlier versions of the dxdir kernel code to corrupt the directory
+when attempting to split a node containing an empty directory entry.
+
+E2fsck could sometimes in rare circumstances leave the indexed flag
+set after a small directory was optimized by compressing it instead of
+indexing it. (This should never happen in real life, since
+directories that small wouldn't have been indexed, but better safe
+than sorry.)
+
+E2fsck now only updates the master superblock in all cases. This
+slightly shortens its run time.
+
+Ext2ed can deal with directory entries of length 0; previously it
+would get stuck in an infinite loop.
+
+Fsck now has support for reiserfs volumes when parsing LABEL= and UUID=
+specifiers. (Sourceforge patch #613447)
+
+Badblocks will now work correctly on read-only devices such as
+CD-ROM's. (Sourceforge patch #600451)
+
+Updated and clarified man pages. (Addresses Debian bug #167108)
+
+
+E2fsprogs 1.29 (September 24, 2002)
+===================================
+
+Fixed a bug in e2fsck which could corrupt a directory when optimizing
+it (via the -D option) or rebuiliding the hash tree index with a 1 in
+512 probability, due to a fence post error.
+
+Fixed a bug in the LVM support code which caused LABEL='xxx' not to
+work correctly.
+
+Mke2fs now enables the directory indexing flag by default. (Since
+this is a compatible feature flag, it's safe to do so.)
+
+Tune2fs will support setting the directory indexing feature flag. It
+will automatically set up the default hash algorithm and hash seed
+fields in the superblock.
+
+If the bone-headed user enters the root filesystem twice in
+/etc/fstab, the -R option which skips the root filesystem will skip
+all of them. (Addresses Debian bug #159423). Note! This is not a
+precedent for dealing intelligently with any other kind of doubled
+entry in /etc/fstab!
+
+
+Programmer's notes:
+-------------------
+
+Removed perror declaration in lib/et/internal.h. All modern systems
+can be expected to define perror() these days. Besides, the lib/et
+code wasn't using perror at all anyway. :-)
+
+
+E2fsprogs 1.28 (August 31, 2002)
+================================
+
+Add support for the Hashed-Tree Directory Indexing to e2fsck. Support
+for setting the htree flag is not included yet, although it can be
+manually turned on via the debugfs program.
+
+Clarified e2fsck error message which is printed when it cannot find
+sufficient contiguous block when relcating filesystem metadata.
+
+Added support for building an EVMS plugin module for ext2/3. This
+module is substantially the same as the EVMS module shipping with EVMS
+1.1, with one or two bugfixes. E2fsprogs can also build this plugin
+for use with EVMS 1.0 (which did not include the ext2 plugin module),
+if the configure --enable-old-evms flag is given.
+
+Fsck will search through EVMS volumes when trying to resolve
+filesystem specifications such as LABEL=xxx or UUID=xxx.
+
+Added a new utility program, /sbin/findfs, which will return
+filesystem specifications such as LABEL=xxx or UUID=xxx, and prints
+the device name.
+
+Update and clarified various man pages. (addresses Debian Bug #145044,
+#146437, #131350, #151990, #144621, #141938)
+
+If there are no filesystems specified on fsck's command line, fsck now
+treat that as if the -As options were given. Previously it would
+simply do nothing. (Addresses Debian Bug #153102)
+
+Mke2fs no longer treats a failure to be able to clear the MD signature
+at the end of the filesystem as a fatal error. (Addresses Debian Bug
+#155007)
+
+The e2p library functions (which are used by lsattr and chattr) now
+double check to make sure the file is a regular file or directory
+before attempting to use the ext2 ioctls. Some device drivers
+unfortunately respond to the ext2 ioctl's with unknown behaviour.
+(Addresses Debian Bug #152029).
+
+The extended attribute handling has been updated to correspond with
+the latest V2 bestbits ACL code.
+
+Fixed bug in e2fsck which caused it to not clear the dtime field when
+processing truncated inodes on the orphan list. This could cause data
+loss(!) if a filesystem is rebooted before a truncate has been
+committed.
+
+E2fsck now uses red/black trees in pass1b, which removes some O(n**2)
+algorithms. This makes e2fsck much faster in the case of severely
+corrupted filesystems where a large number of blocks are claimed by a
+large number of inodes. (Thanks to the 2.5 IDE device driver for
+inspiring this work.)
+
+Resize2fs has been significantly sped up when shrinking and expanding
+a filesystem by a very small number of blocks (for example, when EVMS
+is converting a partition to be an EVMS legacy volume).
+
+Added a new option to e2fsck, -D, which will optimize or compress all
+of the directories in the filesystem.
+
+E2fsck now catches SIGINT and SIGTERM to make sure it will can
+properly clean up and only exit at safe points. Fsck will pass
+SIGINT/SIGTERM to its child processes, and wait until they have all
+exited before it exits.
+
+The uuid parsing code in the uuid library now properly complains when
+an illegally formated uuid is presented to it. (Addresses Debian bug
+#152891)
+
+Restrict use of the 2.4 setrlimit ABI f*ckup to kernels between 2.4.10
+and 2.4.17, since the workaround can cause problems when using a 2.4
+kernel with an old version of glibc built with the 2.2 headers.
+
+Fixed a bug in mke2fs where it wasn't properly clearing the initial
+superblock used by other filesystems. (Addresses Debian bug #147256.)
+
+Added support for the synchronous directory feature written by Andrew
+Morton.
+
+The debugfs program can delete directories using the rmdir command.
+
+Add support for 8k and 16k filesystems (for systems with page sizes
+that are greater or equal to 8k or 16k, respectively). Note that
+these filesystems can not be mounted on x86 systems, or other systems
+with only 4k page sizes, due to limitations in the current Linux VM
+code.
+
+Resize2fs requires that the filesystem state be valid and have no
+errors; otherwise, e2fsck -f must be run first. (Previously it simply
+required that the last fsck time be greater than the last mount time.)
+
+Configure now defaults the man pages directory to /usr/share/man on
+Linux systems.
+
+E2fsck now offers to truncate inodes which contain too many blocks (so
+that i_blocks would overflow. Also fixed handling of large sparse
+files.
+
+E2fsck now more completely checks for symlink validity, including
+requiring NULL termination and length checks.
+
+E2fsck will offer to try forcing a disk write to remap a bad block
+after finding a read error when reading a filesystem metadata block.
+
+Fixed a bug in debugfs which caused the -b and -s options to crash
+debugfs, as well as breaking the testb, setb, and clearb functions.
+
+Added a bmap command to debugfs which calculates the logical to
+physical block mapping for a particular inode.
+
+Fixed a bug in code which checked to see if a device was mounted which
+sometimes (rarely) failed in the case of a plain file.
+
+Fixed a bug in resize2fs where when it reported an error, it would
+print a message erroneously indicating that the filesystem had been
+resized before it aborted.
+
+When resizing a plain file which is smaller than the requested size,
+resize2fs will attempt to extended the file so that programs like
+e2fsck will not complain that the file is too small.
+
+Resize2fs will print the actual new size of the filesystem when it is
+finished resizing.
+
+Fixed a bug in debugfs where "ls -l" would report incorrectl file type
+information on big-endian systems.
+
+
+Programmer's notes:
+-------------------
+
+Fixed collisions with C++ reserved words.
+
+Added portability fixes for building e2fsprogs on the HURD and AIX.
+
+Added the ext2ed program for creation of test cases. (ext2ed has many
+limitations and bugs which make it unsuitable for production use.)
+
+The ext2fs_read_dir_block2 and ext2fs_write_dir_block now take a new
+flag, EXT2_DIRBLOCK_V2_STRUCT, which will will reverse when the
+name_len field is byte swampped on big-endian machines, since in the
+V2 structure, name_len is a char field which is doesn't need to be
+byte swapped --- except if an old-style kernel had byte-swapped the
+name_len field as part of the V1 structure.
+
+
+E2fsprogs 1.27 (March 8, 2002)
+==============================
+
+The warning messages for mke2fs now go to standard error.
+
+Fixed to make sure "make check" runs all of the test programs with
+LD_LIBRARY_PATH set, so that we test the libraries in the build tree.
+
+The mke2fs program checks the boot sector for the BSD disk label, and
+avoids erasing it if it is there.
+
+Fixed a bug in e2fsck which caused it to core dump if the journal
+inode was missing when it was supposed to be there.
+
+E2fsck now prints ranges in pass 5 when printing deltas for the block
+and inode bitmaps.
+
+Debugfs's "ls -l" command now will print out the file type information
+in the directory entry.
+
+Create man pages and hard links for fsck.ext3 and mkfs.ext3. If
+mke2fs is invoked as mkfs.ext3, create the filesystem with a journal.
+
+Debugfs can now examine the experimental directory indexing
+information.
+
+Fixed bug in debugfs which caused it to core dump if modify_inode is
+called without an open filesystem.
+
+The debugfs lsdel command now runs its output through a pager first.
+
+When installing manual pages, remove the compressed manual pages first.
+
+Synchronized with Debian's packaging information for e2fsprogs-1.26-1.
+
+Fix the 2.4 resource limitation workaround introduced in 1.26 which
+actually broke things on mips32, sparc32, and Alpha platforms.
+
+Updated the I18N code so that calls to setlocate(LC_CTYPE, 0) are made
+(which is required by the newer libintl libraries).
+
+Programmer's notes:
+-------------------
+
+Fixed various gcc -Wall complaints.
+
+Fixed a few memory leaks in the e2fsck journaling code, and in the
+ismounted code checking for a swap device.
+
+Add new inode I/O abstraction interface which exports an inode as
+an I/O object.
+
+Exported ext2_file_flush as a public interface.
+
+In ext2_file_write, we now mark the buffer void * argument as a const, since ext2_file_write doesn't modify the buffer.
+
+Lots of small random portability fixes to make e2fsprogs build under
+AIX --- even without the 5L compatibility toolkit, and even using the
+uber-crippled AIX native C compiler.
+
+
+E2fsprogs 1.26 (February 3, 2002)
+=================================
+
+Dumpe2fs will keep going now if the bad block inode can't be read.
+(Previously it stopped with a fatal error.)
+
+E2fsck will now give an opportunity to run the journal even if the
+recovery flag is not set. This is the default behaviour if e2fsck is
+using a backup superblock, since the needs_recovery flag will never be
+set in the backup superblock copies.
+
+E2fsck now automatically finds the backup superblock/group descriptors
+even when the primary superblock is completely destroyed for 2k and 4k
+filesystems. (Previously it just guessed/assumed that we were dealing
+with a 1k filesystem in that case, and users had to manually specify
+the backup superblock number.)
+
+Fixed a bug in e2fsck where it dereferences a null pointer when there
+is a problem opening a filesystem in preen mode.
+
+E2fsck now handles external journals correctly; previously it trashed
+the external journal device if the journal needed to be replayed.
+
+Work around ulimit incompatibility problem caused by recent 2.4
+kernels; the unix IO module will automatically try to set any resource
+limits to be infinite on startup.
+
+Fixed a bug in e2fsck where it wasn't allocating a new block or inode
+bitmap if it wasn't present and the blocksize was 2k or 4k.
+ (Addresses Debian Bug #116975)
+
+E2fsck will check and fix botched ext3 V1 to V2 superblock updates by
+clearing the new V2 fields if they do not make sense or if the ext3
+superblock is version 1 superblock.
+
+E2fsck will automatically relocate the ext3 journal from a visible
+file (i.e., /.journal) to an hidden inode if the filesystem has been
+opened read/write. This allows the users to add a journal while the
+filesystem is mounted, but the next time the system is rebooted, the
+journal file will disappear. This avoids problems with backups,
+stupid operators with superuser bits, etc.
+
+Fix a bug in fsck where it would not support a filesystem type of
+"auto" if the device was specified in terms of LABEL=xxx or UUID=xxx.
+
+Fsck now supports fstab entries of the form "ext3,ext2". It will also
+automatically identify reiserfs filesystems.
+
+The number of processes spawned by fsck can now be limited using the
+FSCK_MAX_INST environment variable.
+
+Fsck now searchs the LVM proc hierarchy to find logical volumes which
+should be searched for UUID and label information.
+
+Work around a bug in 2.4.10+ kernels by trying to unset the filesize
+limit if at all possible, when opening a block device. (The filesize
+limit shouldn't be applied against writes to a block device.)
+
+In mke2fs and e2fsck, specifying the -c option twice will now do
+a read/write test on the disk. Update the man pages to encourage
+using the -c option, and to discouraging running badblocks separately,
+since users tend to forget to set the blocksize when running
+badblocks.
+
+Mke2fs now automatically clears the immutable attribute on a
+pre-existing .journal file left over from a previous failed attempt to
+add a journal to an alreadyy-mounted filesystem.
+
+Fixed mke2fs's exit codes to consistently indicate when the mke2fs
+operation failed.
+
+Mke2fs now creates the lost+found directory with permissions of 0700,
+so that files that had previously lived in protected directory are
+safe if they get dropped in lost+found and the system administrator
+doesn't deal with immediately. (Addresses Debian #bug 118443)
+
+Mke2fs and e2fsck (and all programs that use the
+ext2fs_check_if_mounted function) will now properly identify that a
+device is mounted, even in cases where devfs has confused things with
+multiple devices names with the same identity, or if a dim-witted
+system administrator has done something stupid like creating device
+file aliases in their home directory. Also now checks for swap devices
+by using /proc/swaps. (Addresses Debian bug #106622)
+
+Added a new option (-T) to tune2fs which sets the time a filesystem
+was last checked.
+
+Speed up e2image when creating sparse raw image files by optimizing
+away excess lseek() system calls.
+
+Fix support of large (> 2GB) files when used as a filesystem in
+mke2fs, tune2fs, debugfs, and findsuper.
+
+Debugfs's stat and icheck commands now properly deals with large (>
+2GB) files.
+
+Debugfs's set_super_value command now prints out the list of valid
+superblock fields which can be set using the command.
+
+Debugfs's rm and kill_file command now updates the superblock free block
+and inode counts, thus keeping the filesystem consistent.
+
+Debugfs's lsdel command now takes an optional argument which allows
+the user to only see the most recently deleted files.
+
+A new command (undel) was added to debugfs which automates
+undeleting a deleted inode and linking it back to a directory.
+
+Debugfs's ls command now takes a new option, -d, which lists
+deleted directory entries.
+
+Debugfs's testb, freeb, setb, and find_free_block commands now take an
+optional count argument.
+
+Add support for a new ext2 file attribute, EXT2_NOTAIL_FL, which will
+be used to signal that a particular inode should not be eligible for
+tail-merging --- this is needed for programs like LILO.
+
+The findsuper (an unreleased, uninstalled utility program) has been
+improved to add extra validity checks and to add a progress meter.
+(It is still an unsupported program; the officially supported way to
+recover from a trashed partition table is to use gpart; findsuper is
+for wizards only. :-)
+
+Debugfs was fixed to compile with "configure --disable-swapfs".
+
+Cleaned up various manual pages. (Addresses Debian bug #119624, #120171)
+
+Added new translation file for Turkish.
+
+Programmer's notes:
+-------------------
+
+Fix general gcc -Wall complaints.
+
+E2fsprogs (mostly) works with the dietlibc.
+
+The programming texinfo file has been expanded to include description
+of additional libext2fs functions. (Still not compeltely done, but a
+lot of the more important functions have been documented.)
+
+Added a umask structure to struct_ext2_filsys, which currently only
+modifies the behaviour of ext2fs_mkdir(), but if we add any file
+creation functions to libext2fs, we should also make sure they respect
+the umask setting.
+
+The build-rpm script was fixed to be a bit more safe.
+
+The tests' Makefile now has a way of automating test case creation
+for e2fsck, using "make testnew".
+
+Created a new function, ext2fs_dir_iterate2 which passes more
+information to the callback function (identical to the one used by
+ext2fs_dblist_dir_iterate). The directory iterator functions take a
+new flag, DIRENT_FLAG_INCLUDE_REMOVED, which will return deleted
+directory entries. If the directory entry is deleted, the callback
+function will be called with the entry paraemter set to
+DIRENT_DELETED_FILE.
+
+Added new functions, ext2fs_inode_alloc_stats and
+ext2fs_block_alloc_stats, which takes updates block/inode allocation
+statistics in the bitmaps, block group descriptors, and superblock
+when inodes or blocks are allocated or deallocated.
+
+
+E2fsprogs 1.25 (September 20, 2001)
+===================================
+
+This is primarily a bug-fix release; no new features were added, but
+there are a number of embarassing bug fixes and cleanups applied.
+
+Fix a bug mke2fs which causes stack garbage to be written to disk when
+zapping disk sectors. (This bug could cause mke2fs to core dump for
+some kernels, I suspect with security enhancement patches.)
+
+Remove unneeded #include of <linux/config.h> which was breaking
+building e2fsprogs on the Hurd. (Addresses Debian bug #112414.)
+
+Updated tune2fs man page to reflect the fact that adding or removing a
+journal doesn't require running e2fsck.
+
+Remove use of AC_REQUIRE from autoconf which had been used to prevent
+AC_CANONICAL_HOST from being called twice; unfortunately this causes
+recent autoconf to bomb out since they don't allow AC_REQUIRE to be
+used outside of autoconf macros. Fortunately, it doesn't seem to be
+necessary any more, anyway.
+
+E2fsck will now not fall back to an alternate superblock if the user
+specifies the superblock location explicitly on the command-line.
+This allows easier recovery from a situation where the primary
+superblock and block groups are slightly corrupted, but the backup
+superblocks are completely broken.
+
+Fix problem which caused compile_et and mk_cmds to blow up if
+e2fsprogs was in a directory with a pathname that contained spaces.
+
+We are now more paranoid about checking the entry in /etc/mtab to make
+sure the filesystem is really mounted, since some broken distributions
+(read: Slackware) don't initialize /etc/mtab before checking non-root
+filesystems. (Slackware also doesn't check the root filesystem
+separately, and reboot if the root filesystem had changes applied to
+it, which is dangerous and broken, but there's nothing I can do about
+that.)
+
+Make UUID library C++ friendly by adding appropriate extern "C"
+declarations and using const in the function declarations.
+
+Fix up the com_err texinfo file so that it can product a valid info
+file (previously, it could only be used to generate paper
+documentation using texinfo.tex).
+
+
+E2fsprogs 1.24a (September 2, 2001)
+===================================
+
+Fix brown-paper bug in mke2fs which caused it to segfault when
+printing the version string.
+
+
+E2fsprogs 1.24 (August 30, 2001)
+================================
+
+Revert the BLKGETSIZE64 support, since for some distributions, this
+ioctl has been used by an unofficial kernel patch to update the last
+sector on the disk, and this was causing disk corruption problems as a
+result.
+
+Mke2fs is now more careful about zapping swap space signatures and
+other filesystem/raid superblock magic values so that programs like
+mount who try to use hueristics to determine the filesystem type of a
+partition are less likely to be confused.
+
+E2fsck will no longer complain if the the mode of EXT2_RESIZE_INO is a
+regular file (since Andreas Dilger's on-line resizing tools will set
+its mode bits).
+
+Fixed some minor texinfo, man pages nits for spelling errors,
+texinfo warnings, etc. (Addresses Debian bug #110621.)
+
+E2fsprogs program no longer print the filesystem version number
+(i.e. 0.5b), since it only confuses people and doesn't serve any real
+purpose.
+
+E2fsck will once again compile under libc5, since it will supply its
+own version of strnlen if necesssary.
+
+mke2fs and tune2fs will allow the use of UUID= or LABEL= specifiers
+when specifying the external journal device. tune2fs will also search
+devices looking for the externla journal debice when removing.
+
+E2fsprogs 1.23 (August 15, 2001)
+================================
+
+Add initial support for extended attributes (EA); e2fsck will
+correctly handle a filesystem with EA's and check the EA blocks for
+corruptions.
+
+E2fsck's symlink sanity checking has been cleaned up. It now checks
+the i_size value of fast symlinks, and checks for immutable flags
+being set of symlinks, etc.
+
+E2fsck now offers to clear inodes which are special files that have a
+non-zero i_blocks or i_size field. (The i_size field check was in the
+previous version of the code, but due to a bug it didn't offer to
+clear the inode unless i_size and i_size_high were both non-zero.)
+
+E2image can now create "raw" image files, which only contain the
+filesystem metadata placed in a spare file so that e2fsck, dumpe2fs,
+debugfs, etc., can be run directly on the raw image file.
+
+Add support for the 64-bit block device patches.
+
+Fixed bugs in creating external journals with a 1k blocksize.
+
+Add initial support for external journals (so long as the external
+journal only supports a single filesystem) in e2fsck.
+
+Remove requirement for needing to run fsck on a filesystem after
+removing a journal (either internal or external).
+
+The man pages now document how to create and manage external journals.
+
+Speed up the check of an ext3 filesystems by avoiding a needless flush
+of all of the superblock and block group descriptors.
+
+Speed up creating an internal journal using tune2fs in the case where
+the filesystem has a lot blocks already allocated.
+
+Tune2fs has been fixed to make sure that only error messages go to
+stderr, and normal message go to stdout. (Addresses Debian bug #108555)
+
+Fixed a minor bug in mke2fs; if -O none is passed to mke2fs, it will
+now not set the sparse_super feature. (Addresses Debian bug #108165)
+
+Add support in fsck for the filesystem type "auto".
+
+Fsck -A will not try to interpret device names for filesystems which
+have a pass number is 0. (Addresses Debian bug #106696).
+
+Fsck prints a warning message if now valid filesystems are passed to
+it. (Addresses Debian Bug #107458.)
+
+E2fsck now gives an explicit warning if there filesystem still has
+errors at the end of the run. (Addresses Debian bug #104502)
+
+E2fsck will set the EXT2_ERROR_FS flag if the journal superblock
+reflects an error. E2fsck will also not run the orphan list if the
+filesystem contains errors, since the orphan list might be corrupted.
+
+E2fsck now prints the number of large files when given the -v option.
+
+Fixed minor memory leaks in e2fsck.
+
+Some minor man pages updates. (Addresses Debian bug #30833, #108174)
+
+
+E2fsprogs 1.22 (June 22, 2001)
+==============================
+
+Fixed a bug in e2fsck's handling of orphan inodes which are special
+files (i.e., block/character device files, named FIFO's, etc.).
+
+Fixed a bug accidentally introduced in e2fsprogs 1.21 which caused
+tune2fs to fail at adding a journal to a mounted filesystem.
+
+Fixed a few big-endian bugs in e2fsprogs
+ * The directory block functions were accidentally reporting
+ some directories as corrupted when they weren't.
+ * If e2fsprogs is compiled --disable-swapfs, the C language
+ equivalents weren't being included for big-endian platforms.
+ (Fixes Debian bug #101686).
+
+Fixed a Hurd compilation problem. (Addresses Debian bug #101361)
+
+Programmer's notes:
+-------------------
+
+Use platform independent method of defining the BLKFLSBUF and FDFLUSH
+ioctls, and allow them to be defined for non-i386 platforms.
+
+The uuid.h header file is now protected against multiple inclusions.
+
+E2fsprogs is now being developed using BitKeeper. Changed the test
+scripts to deal with BK's stripping CR characgters from text files,
+and changed the top-level Makefile.in to avoid including BitKeeper
+files when generating the source tarball.
+
+
+E2fsprogs 1.21 (June 15, 2001)
+==============================
+
+Added new configure flags which allow a subset e2fsprogs to be built;
+this is most useful for boot floopies, since the resulting shared
+libraries and programs are slimmed down by removing features that
+aren't necessary for a boot floppy. The new flags that were added
+are: --disable-swapfs, which removes support for byte swapping old
+legacy PPC/68k filesystems, --disable-debugfs, which removes support
+for debugfs from the libext2fs library, --disable-imager, which
+removes support for the e2image program, and --disable-resizer, which
+removes support for resize2fs.
+
+E2fsck now prints the number of mounts or days elapsed since the last
+check when e2fsck is forced to check an otherwise clean filesystem.
+
+Tune2fs now prints an informative message about how often a filesystem
+will be checked when adding a journal to the filesystem, to remind the
+user that he/she may want to adjust those parameters using tune2fs
+-c/-i.
+
+Worked around hurd brain-damage which causes e2fsck to sometimes
+believe a filesystem is the root filesystem based on device numbers
+(since Hurd doesn't have dev_t's, which is arguably a POSIX.1
+violation).
+
+Fixed a bug introduced in 1.20 which caused e2fsck to abort with an
+erroneous error with the -F option was specified.
+
+Fixed a ext3 recovery bug in the revoke handling; synchronized with
+ext3 0.7a.
+
+Fixed two bugs in e2fsck's handling of dup block handling, dealing
+with relatively uncommon edge cases: a directory with an indirect
+block which is claimed by another file, and when the last inode in the
+filesystem has blocks claimed by another file.
+
+E2fsck now checks to see if the i_size field of a fast symlink is too
+big, and offers to clear the symlink if so.
+
+E2fsck now checks to see if i_size_high of special files is non-zero,
+and offers to clear i_size_high.
+
+Fix e2fsck's handling of incompatible journal flags so that the user
+has chance to abort, and then has the option to clear out the journal
+entirely. (Addresses Debian bug #98527.)
+
+Fixed a bug in fsck which could cause it to core dump if a mix of
+standard and non-standard device names are used in /etc/fstab.
+(Debian bug #100559)
+
+Fixed a bug in debugfs which caused read errors when copying a file to
+not be noticed.
+
+The debugfs set_super_value command can now modify the s_lastcheck field.
+
+Fixed a bug in lsattr and chattr which was accidentally introduced in
+1.20 to support > 2GB files; both lsattr and chattr wasn't reading
+directories correctly because the change modified the layout of struct
+dirent to be incompatible with the libe2p shared library.
+
+Cleaned up the mke2fs manual page and included a discussion about why
+it's good to periodically check the filesystem even when journaling is
+enabled.
+
+Programmer's notes:
+-------------------
+
+Fix general gcc -Wall complaints.
+
+The types needed by the ext2 header files are now provided by
+lib/ext2fs/ext2_types.h, instead of include/asm/types.h.
+
+Integers are now preferred to longs when trying to find a 32-bit type
+in ext2_types.h. Also, if linux/types.h has already been defined,
+don't try to redefine the types.
+
+Fixed make depend script so that it automatically corrects the
+pathname cleanups performed by make -M, so I don't have to fix them up
+by hand.
+
+Fixed the d_loaddump test case to be more robust, and not depend on
+bash'isms.
+
+Removed debugfs's dependence on pread(), which was accidentally
+intrudced in e2fsprogs 1.20
+
+Fixed a performance bug in the libext2fs's icount routine; the size
+estimate of the icount array was incorrectly being calculated.
+
+Removed use of the badblocks compatibility functions in the e2fsprogs
+programs.
+
+Added paranoia code which protects against strange cases where /etc
+isn't on the root filesystem, or if /etc/mtab doesn't exist.
+
+The header file ext2_types.h is now installed.
+
+Autoconf is used to determine when we are on big-endian machines,
+instead of doing run-time tests, to save a few bytes of code.
+
+The ext2fs_mark_generic_bitmap and ext2fs_unmark_generic_bitmap
+functions are no longer inline functions, which saves space and
+doesn't really cost any real performance.
+
+The ext2fs library no longer depends on the e2p library. (What need
+there was of it --- namely, fsetflags, was coded in-line).
+
+Fixed the makefile so that lib/ext2fs/ext2_types.h is generated even
+when the user is stupid and tries compiling the package using "make
+install" as root.
+
+Miscellaneous code cleanups:
+ * Added missing files from Makefile.in's SRCS file, so that
+ their dependencies would be properly calculated.
+ * Removed redundant code
+ * Fixed comments in code
+ * Removed no-longer unneeded argsused #pragma.
+
+
+E2fsprogs 1.20 (May 20, 2001)
+=============================
+
+Add support for replaying the ext3 journal purely in user mode,
+including handling the orphaned inode list. Used code contributed by
+Andreas Dilger, with bug fixes and the orphaned inode handling done
+by Theodore Ts'o.
+
+The mke2fs and tune2fs programs can create or modify a filesystem to
+include an ext3 journal. Tune2fs also can be used to remove an ext3
+journal from a filesystem.
+
+E2fsck will now check for the existence of a linked list of orphan
+inodes in the superblock, and clear those inodes before starting the
+rest of the filesystem check (but after the journal playback).
+
+E2fsck now validates the file descriptor passed to the -C option,
+which saves against the completion bar getting written to an
+unexpected location, such as the disk being checked. (Debian
+bug/wishlist #55220)
+
+E2fsck will now bump the filesystem revision number from zero to one
+if any of the compatibility bits are set.
+
+Fixed a bug where a badly corrupted directory on a big endian system
+could cause e2fsck to die with a bus error. The
+ext2fs_read_dir_block() and ext2fs_process_dir_block() functions in
+the ext2 library now does alignment sanity checks on the rec_len field
+of the directory entry before using it.
+
+The ext2 library has been enhanced to make tune2fs safe to run on
+mounted filesystems. (Users could usually get away with using tune2fs
+on mounted filesystems before, but with the advent of ext3 and
+journaling, it became important to make tune2fs was *really* safe for
+use even when the filesystem being modified is mounted.) E2label is
+now implemented by tune2fs using an argv[0] dispatch, so that e2label
+is also now safe for use on mounted filesystems.
+
+Added a new program, e2image, which creates a backup of critical ext2
+filesystem data structures. The generated image file can be examined
+using dumpe2fs and debugfs. In the future, e2fsck will be able to use
+the image file to help recover very badly damaged filesystems.
+
+Fixed a number of LFS bugs in e2fsck; very, very large (> 2**42) files
+no longer cause e2fsck to bomb out. Also treat files > 2GB as being
+large file when deciding whether or not the filesystem has large files.
+
+Fixed lsattr and chattr so that they work correctly on large files.
+(Fixes Debian bug #72690.)
+
+Removed limitation in get_device_size() which imposed a one terrabyte
+filesystem limitation. (Most 2.2 kernels still have a signed int
+problem which cause 1 TB block device limitation. Fortunately, the
+kernel patches to fix this are much easier than fixing the 2TB
+limitation in the kernel. :-)
+
+A max_mount_count of zero is now treated as if no mount count were
+set. (Previously, no mount count was indicated by using -1, and a
+mount count of zero caused e2fsck to always be run.)
+
+Mke2fs supports two new filesystem types largefile and largefile4.
+
+Mke2fs now adds some randomness in s_max_mount_count so that multiple
+filesystems won't be all checked at the same time under normal
+operations.
+
+Fixed bug in the progress bar printing code which could cause e2fsck
+to core dump on an illegal filesystem.
+
+Fixed bug in fsck which could allow more than one instance of e2fsck
+to be printing a progress bar. (Debian bug #65267)
+
+Fsck using a UUID or a LABEL specifier will work even if devfs is
+compiled into the kernel and not mounted. If the pathnames in
+/proc/partitions are incorrect, fsck will search /dev for the correct
+device (using the new ext2fs_find_block_device library function).
+Fsck now also checks the RAID devices first so that they are properly
+found when they are in use. Support has also been added to support
+additional IDE disks and the DAC 960 device names. (Debian bug #94159)
+
+Fixed a bug in fsck which caused it not deal properly with 16
+byte long filesystem labels.
+
+Fsck's -t option has been made a lot more flexible. The semantics for
+what happens if a comma-separated list to fsck has been regularized,
+and it is now possible to filter what filesystems will get checked
+based what is in the filesystem's fstab entry's option field. (Debian
+bug #89483.)
+
+The dumpe2fs program can now print out the group description
+information in hex, and also prints the location of the superblock and
+block group descriptor for those block groups that have them.
+
+Mke2fs now clears the ext2 superblock before it starts creating a
+filesystem, so that the superblock magic number is only written if the
+filesystem creation process successfully completes.
+
+The debugfs program's stat command now pretty-prints the blocks used
+by an inode so that it's more compact and informative.
+
+The debugfs stats command now uses the same libe2p code (which is used
+by dumpe2fs) to print the superblock header information. This is more
+complete, and it avoids a bit of code duplication.
+
+Added a new debugfs command, set_super_value (ssv) which allows the
+user to set arbitrary superblock fields.
+
+Debugfs was extended to support inode numbers in hex (by prefixing
+them with 0x), and so that modify_inode can set the inode generation
+number. Also, there is now a new function command called logdump
+which will dump an ext3 journal.
+
+Fixed a bug in debugfs so that quitting out of the pager doesn't kill
+debugfs.
+
+Debugfs's dump command now stops immediately upon reporting a disk
+read error. (Fixed a bug in ext2fs_file_read library routine which
+caused debugfs not to stop.) (Debian bug #79163)
+
+On systems with /proc/mounts (mainly Linux systems), /proc/mounts is
+checked before /etc/mtab is used, since /proc/mounts is more likely to
+be accurate.
+
+Added portability fixes for Solaris and Linux/ia64.
+
+Various manual pages were clarified and cleaned up. (Fixed debian
+bugs #63442, #67446, and #87216)
+
+
+Programmer's notes:
+-------------------
+
+The e2fsck message printer now supports %Iu and %Ig, which will print
+out the inode's user and group owners, respectively.
+
+E2fsprogs now includes its own version of include/linux/ext2_fs.h, so
+that no longer dependent on the system having the correct version of
+the kernel header files.
+
+Added a new function to libext2, ext2fs_find_block_device(), which
+searches the system (i.e., /dev, /devfs, /devices) for a pathname to a
+device given its device number.
+
+Added a new function to libext2, ext2fs_sync_device, which centralizes
+all of the places which might try to use the BLKFLSBUF or FDFLUSH
+ioctls (and usually failing to define them since the system header
+files don't usually do this for us, and we're trying to avoid usage of
+kernel include files now).
+
+Added new utility programs in tests/progs: random_exercise and
+hold_inode. They aren't built by default; they're useful for
+exercising ext3 filesystem code.
+
+Added a new ext2 filesystem flag, EXT2_FLAG_SUPER_ONLY, which causes
+the filesystem close functions to only update the superblock, and to
+not touch the block group descriptors. Needed by tune2fs when
+modifying a mounted filesystem.
+
+Got rid of struct ext2fs_sb and replaced it with the standard struct
+ext2_super_block from include/linux/ext2_fs.h. Note: this may break
+source (but not binary) compatibility of some users of the ext2
+library. Those applications should just simply do a global search and
+replace of struct ext2fs_sb with struct ext2_super_block, and include
+the new header file <ext2fs/ext2_fs.h> which defines it.
+
+The ino_t type has been renamed ext2_ino_t to protect applications
+that attempt to compile -D_FILE_OFFSET_BITS=64, since this
+inexplicably changes ino_t(!?). So we use ext2_ino_t to avoid an
+unexpected ABI change.
+
+The Makefiles have been reworked so that "make check" can be run from
+the top-level Makefile.
+
+Fix general gcc -Wall complaints and removed dead code.
+
+Remove use of NOARGS, because we assume everyone does ANSI C these
+days.
+
+Added build-rpm script from sct.
+
+New functions ext2fs_image_{inode,super,bitmap}_{read,write} added
+to support e2image.
+
+New function ext2fs_flush_icache which must be called if the
+application program modifies the inode table blocks without going
+through ext2fs_write_inode() interface.
+
+New ext2fs_check_mount_point() function, which will return the mount
+point of a device if mounted.
+
+The io_channel abstraction now has an optional interface,
+io_channel_write_range, which allows specific byte ranges to be
+written.
+
+The unix_io IO channel now supports write-through caching, so that
+journal creation is more efficient.
+
+Added x86 assembly language routines to support byte swapping, to
+reduce executable size.
+
+Fixed bug in the utility program subst so that it's possible to
+replace a substitution variable with a zero-length string.
+
+Fixed numbering e2fsck pass1 problem numbers; an extra zero had
+slipped into some of the problem number.
+
+E2fsprogs 1.19 (July 13, 2000)
+==============================
+
+Release the resize2fs program since the timeout before it could
+be released under the GPL has finally expired.
+
+Add experimental support needed for the ext2 compression patches.
+This requires compiling e2fsprogs with the --enable-compression flag
+to the configure script.
+
+Added ext3 journalling support. E2fsck will run the journal (if
+necessary) by temporarily mounting the filesystem. /sbin/fsck.ext3 is
+installed as a symlink to e2fsck. Fsck has been taught about ext3,
+and treats it the same as ext2 in terms of the progress bar logic.
+Dumpe2fs will display the superblock journaling information if the
+filesystem has a journal. The ext2 library will now permit opening an
+ext3 filesystem with the recovery flag set. This is necessary for
+on-line dump's to work correctly, but there may be issues with this
+working well since ext3 is much less agressive about syncing blocks to
+the filesystem, since they're safe on the journal.
+
+Tune2fs and e2fsck have been changed to allow the mount_count check to
+be disabled by setting max_mount_count to -1. (This was already
+supported by the kernel.)
+
+Create a symbolic link for fsck.ext3, since the e2fsprogs utilities
+are used for ext3 as well.
+
+Added internationalization support for e2fsprogs; must be enabled
+by passing --enable-nls to configure.
+
+Always use the provided ext2fs header files to insulate ourselves from
+kernel version changes. Which include files are used by e2fsprogs
+have also been cleaned up to improve portability.
+
+Limit the number of times that e2fsck updates the progress bar so that
+people who are booting using a 9600 baud console don't get swampped by
+too many updates.
+
+Improved the loop detection algorithm in e2sck's pass #3 so that it is
+much, much faster for large filesystems with a large number of
+directories.
+
+The memory footprint for e2fsck is now slightly smaller than before.
+
+E2fsck now checks if special devices have a non-zero size, and offers
+to clear the size field if it finds such an inode.
+
+E2fsck now checks if special devices have the append-only flag set,
+and offers to clear the inode.
+
+E2fsck now properly handles some "should never fail" cases during a
+bitmap copy in pass5.
+
+E2fsck now properly prints control characters in filenames as ^A .. ^Z.
+
+E2fsck now calculates the correct location of the backup superblock in
+the case of filesystem blocksizes > 1k.
+
+Fixed a bug in e2fsck's calculation of the number of inodes_per_block
+which normally didn't cause problems under most filesystem parameters,
+but could cause a valid superblock to be rejected in extreme cases.
+Other checks for validating superblock values were made more
+stringent.
+
+Added non-destructive write testing to the badblocks program, courtesy
+of David Beattie. The badblocks also now has an option to input the
+current set of bad blocks, so that known bad blocks are skipped to
+speed up the badblocks test. There is also a persistent rescan
+feature which causes badblocks to run until it has completed some
+number of passes without discovering any new bad blocks.
+
+Badblocks now checks to see if the device is mounted and refuses to do
+the tests involving writing to the device if it is mounted. Also,
+badblocks now allows the number of blocks to be checked to be
+defaulted to the size of the partition.
+
+Fixed a bug in fsck which didn't allow non-root users to be able to
+check filesystems if there were any LABEL= or UUID= entries in
+/etc/fstab.
+
+The Hurd doesn't support the filetype filesystem feature. The mke2fs
+program now makes sure that for the Hurd, the filestype feature is
+turned off. E2fsck will check to see if the filetype feature is
+turned on for Hurd filesystems, and offer to turn off the feature.
+
+Mke2fs now has a safety check to make sure the number of blocks do not
+exceed 32 bits even on a 64 bit platform.
+
+Really fixed a bug in fsck to allow "fsck -As" to run interactive
+fsck's. (For those people who like to do interactive fsck's in the
+/etc/rc scripts!?!)
+
+Debugfs has a few new features: the rdump command, which will do a
+recursive dump of a directory and all of its contents, and the lcd
+command which does a local chdir (much like the ftp command of the
+same name). In addition, the debugfs program and the open_filesystem
+command now takes three new options: -b and -s, which allows the
+blocksize and superblock location to be specified, and the -c option
+which is used in catastrophic situations where the block group
+descriptors are corrupt. If the -c option is specified, debugfs will
+skip trying to read in the block and inode bitmaps.
+
+Debufs's lsdel command was fixed to handle bad blocks in the inode
+table.
+
+A Y2K bug in debugfs's "ls -l" handling was fixed by switching to use
+4 digit years.
+
+General improvements in error messages
+
+ - Mke2fs prints a sane error message if the partition size is zero
+ (usually because the partition table wasn't reread by the
+ kernel due to the partition being busy), instead of "invalid
+ argument passed to ext2 library while initializing superblock".
+
+ - Fsck now prints more self-explanatory message if an invalid UUID=
+ or LABEL= specification is passed to it.
+
+UUID library changed to use the LGPL.
+
+Fixed a bug in the UUID library where very rapid calls to the
+time-based UUID generator could cause duplicate UUID's to be returned.
+This was not a problem for e2fsprogs, but it could be a problem for
+other users of the library.
+
+Make the UUID library more robust in the face of missing or an
+improper /dev/urandom or /dev/random files.
+
+Added some random portability fixes for Solaris.
+
+Some minor man page updates.
+
+Fixed a memory leak in the ss library.
+
+
+Programmer's notes:
+-------------------
+
+We now try to use lseek64 and open64 from the LFS if possible.
+
+The 3rd parameter in e2p's print_flags is now a flags word, instead of
+a boolean option.
+
+The mark and unmark bitmap functions now return the previous state of
+the bit that was being changed, which is useful for some speed
+optimizations.
+
+The following functions have been added to enhance the badblocks list
+handling in libext2fs: ext2fs_write_bb_FILE, ext2fs_read_bb_FILE2, and
+ext2fs_badblocks_equal.
+
+The ext2 header files now have the latest journalling fields to the
+superblock.
+
+The ext2fs_mkdir function in libext2fs now properly backs out of error
+conditions robustly.
+
+Cleaned up makefiles:
+ - to cleanly compile with the -j flag.
+ - so distclean removes all generated files.
+ - so in case of an error while installing header files, the make aborts.
+
+Fix test_script so that it works correctly when compiling in the
+source directory.
+
+The random UUID generation routine has been made slightly better in
+the case where /dev/random doesn't exist. (Use of randomly-based UUID
+is still not recommended if /dev/random doesn't exist, however; it's
+better to use the time/ethernet MAC address UUID in this case.)
+
+Clean up the build process so it's more friendly in case of missing
+directories.
+
+The ext2fs header file can now be #include'd into C++ programs.
+
+The e2p.h header file is now installed.
+
+Added workaround to a gawk 3.0.5 bug in lib/ss/mk_cmds.
+
+
+
+E2fsprogs 1.18 (November 10, 1999)
+==================================
+
+Fix a core dumping bug in e2fsck if an imagic inode is present or
+(more rarely) if the filesystem is badly corrupted enough that e2fsck
+has to restart pass 1 processing. E2fsck now closes the filesystem
+before freeing a large number of its data structures, so in the case
+of future memory faults, at least the fixed filesystem will be fully
+written out.
+
+If a filesystem doesn't support imagic inodes, and e2fsck discovers an
+imagic inode, it will offer to clear the imagic flag.
+
+E2fsck will now offer to clear the immutable flag on special files
+(device/socket/fifos) when running it in non-preen mode.
+
+E2fsck will now set the filetype when creating /lost+found, and when
+connected orphaned inodes to /lost+found.
+
+Debugfs's ncheck and icheck commands now handles the case where there
+are bad blocks in the inode table without bombing out.
+
+The badblocks list processing code has been made more efficiently for
+appending a large number of (ordered) badblocks to the badblocks list.
+
+Some minor man page updates.
+
+Fsck now allows interactive e2fsck's when using fsck -As (not a common
+mode, but some people like to do this in boot scripts for silly reasons).
+
+Programmer's notes:
+-------------------
+
+The internal e2fsck problem code for PR_2_SPLIT_DOT was fixed to meet
+with the problem code convention.
+
+The badblocks list regression test program has been updated to work
+with previously made API name changes.
+
+The ext2fs_free() command now uses the new badblocks API to avoid
+using the compatibility layer.
+
+Added new regression test cases; the run_e2fsck test script now
+supports the ability for a test case to run a prepratory command
+before running e2fsck.
+
+E2fsprogs 1.17 (October 26, 1999)
+=================================
+
+Fixed nasty typo in fsck which caused parallelized fsck's to go into an
+infinite loop.
+
+Fixed a bug in fsck where it used strncmp to compare a binary UUID,
+thus potentially causing problems if a binary UUID contained a NULL
+character.
+
+E2fsck now uses stricter checks for directory entries in pass 2:
+zero-length filenames are not allowed; neither are 8 byte long
+directory entries.
+
+The debugfs "dirty" command now clears the filesystem valid bit.
+(Previously this just set the dirty-as-in-needs-writing-out-to-disk
+bit in the in-core superblock image. The new functionality is more
+what the user expects, and is more useful.)
+
+Added a debugging hook to test parallel fsck; if the environment
+variable FSCK_FORCE_ALL_PARALLEL, then filesystems on the same drive
+will be checked in parallel when they normally would not be.
+
+Programmer's notes:
+-------------------
+
+Fixed some #ifdef's for compilation under the Hurd OS.
+
+Fixed minor W2K compatibility problems.
+
+Fixed some miscellaneous GCC warnings.
+
+
+E2fsprogs 1.16 (October 22, 1999)
+=================================
+
+Fixed a race condition bug in fsck; when printing a progress bar, if
+checking multiple filesystems in parallel, it was possible for fsck to
+send e2fsck a SIGUSR1 signal before e2fsck had installed its signal
+handler, which would cause it to terminate with a signal 10.
+
+E2fsck now properly handles filesystems that have the
+INCOMPAT_FILETYPE feature turned on. It can be used to convert a
+filesystem into using or not using FILETYPE feature.
+
+E2fsck now properly handles filesystems that have the IMAGIC feature
+turned on (this is used on Linux AFS servers).
+
+The mke2fs program now creates filesystems that have the filetype and
+sparse_superblock features enabled by default, unless it is run on a
+pre-2.2 kernel. These features are not supported by a pre-2.2 kernel,
+so there is now a new flag -O which allows the user to specify with
+which features she would like to create the filesystem; "mke2fs -O
+none" will create a filesystsem compatible with 2.0 kernels.
+
+The tune2fs program now has a -O option which allows the user to set
+and reset "safe" filesystem features. Currently, the only ones which
+allows to be modified are the filetype and sparse_superblock features.
+Note setting or clearing either feature will require running e2fsck on
+the filesystem afterwards. (n.b. Clearing the sparse_superblock feature
+requires that there is enough free space on the filesystem for the
+extra superblocks which will be created by e2fsck.)
+
+Debugfs can now set and print filesystem features in the superblock
+using the "features" command. Dumpe2fs will print out the complete
+set of features when listing the superblock.
+
+Dumpe2fs has new options -f (force) and -h (header-only).
+
+Fixed a bug in e2fsck which could cause the PROGRAMMING ERROR/bonehead
+message to come up. This could happen when decrementing or
+incrementing a link count could result in an overflow.
+
+Fixed a bug in e2fsck where the block count on the lost+found
+directory would not be properly incremented when the directory was
+expanded to the point where an indirect block needed to be allocated.
+
+E2fsck now makes some additional sanity checks on the superblock to
+avoid crashing or giving a memory allocation error if some of the
+values in the superblock are unresonable (but the superblock otherwise
+looks valid).
+
+Fixed a bug in e2fsck where a very badly corrupted filesystem might
+require two passes to completely fix the filesystem. This happened if
+an inode claimed blocks that was part of the filesystem metadata
+(typically, when garbage was written into an inode table or indirect
+block, since this kind of filesystem corruption normally doesn't
+happen otherwise).
+
+On the Alpha, glibc declares st_flags although it isn't actually used;
+the configure script was improved to detect this case so that
+e2fsprogs can avoid using the non-functional stat field.
+
+The manual pages were updated to use a more consistent formatting
+style consistent with standard Unix man pages. Mke2fs's man page
+added documentation for a few previously undocumented options.
+
+Fixed minor display bugs in tune2fs and mke2fs.
+
+Programmer's notes:
+-------------------
+
+Improved portability of e2fsprogs to non-Unix systems (in particular, NT).
+
+Added features to parse and print feature strings into the e2p library.
+(e2p_feature2string, e2p_string2feature, e2p_edit_feature).
+
+ext2fs_mkdir() and ext2fs_new_dir_block() now creates directories
+whose directory entries contain proper filetype information if the
+filesystem supports it.
+
+ext2fs_link() now uses the low 3 bits of its flags parameter to pass
+the directory entry filetype information. This is used to set the
+directory entry filetype information if the filesystem supports it.
+
+Fixed a bug in ext2fs_expand_dir() where the block count in a
+directory's inode would not be properly incremented when the directory
+was expanded to the point where an indirect block needed to be
+allocated.
+
+
+E2fsprogs 1.15 (July 18, 1999)
+==============================
+
+Add configuration checks so that e2fsprogs will compile cleanly on
+Linux 2.3 kernels that have renamed i_version to i_generation.
+
+E2fsck now prints a progress/completion bar (and not just a simple
+spinner) if the -C0 option is requested or if it receives a SIGUSR1
+signal. Fsck will automatically manage the (potentially muliple)
+e2fsck processes to print completion bars if it is given a -C option,
+with the right thing happening if multiple filesystems are being
+checked in parallel.
+
+Mke2fs now has better automatic hueristics to determine the filesystem
+parameters to be used for a particular filesystem. Added a new option
+-T which allows the user to specify how the filesystem is to be used,
+which helps mke2fs do a better job selecting the filesystem parameters.
+
+Mke2fs now creates revision 1 filesystems by default, and with the
+sparse superblock feature enabled. The sparse superblock feature is
+not understood by Linux 2.0 kernels, so they will only allow read-only
+mounts of filesystems with this sparse superblocks.
+
+Fix bug where if /dev/null couldn't be opened (should never happen),
+e2fsck would hang in a tight loop.
+
+Make e2fsck handle the case where /lost+found isn't a directory.
+
+E2fsck now uses mallinfo if it exists to get accurate statistics about
+its memory usage.
+
+Fix bug in e2fsck where it wouldn't check to see if a disconnected
+inode had any problems before connecting it to /lost+found.
+
+Add check to e2fsck so it makes sure that total number of inodes in
+the filesystem is a sane number.
+
+Fix fencepost error when clearing an the end of the block bitmap which
+caused the last block in the bitmap not to get cleared.
+
+Cleaned up a number of messages in e2fsck:
+ * The message "Group's #'s copy of the group descriptor..."
+ was fixed so that the correct number would be displayed.
+ * Added missing space in the "disk write-protected" error messsage
+ * Cleaned up the error message printed when a non-interactive
+ e2fsck needs to abort a check because the filesystem
+ appears to be mounted.
+
+Added a new command-line utility, uuidgen, which will create and print
+a UUID.
+
+Make debugfs's icheck command more robust by checking to make sure an
+inode has valid blocks before interarting over the inode's blocks.
+
+UUID generation now uses a random-based scheme whenever possible to
+prevent potential privacy problems.
+
+Man pages for all of the UUID functions in the lirbary were added.
+
+Fixed bug in fsck so it won't coredump if a filesystem not in
+/etc/fstab is given to it.
+
+Fsck now understands the UUID=xxxx and LABEL=yyyy forms in /etc/fstab
+that most of the other mount utilities understands.
+
+Mke2fs will make a filesystem even if it appears mounted if the force
+option is given.
+
+Dumpe2fs has new command-line options which allow a filesystem expert
+to specify the superblock and blocksize when opening a filesystem.
+This is mainly useful when examining the remains of a toasted
+filesystem.
+
+The badblocks program has been updated to display correctly on disks
+with large block numbers.
+
+The badblocks program no longer gives spurious errors when errors
+occur on non-block boundaries, which is common if the blocksize is
+larger than 1k.
+
+Mke2fs will sync the disk device every MKE2FS_SYNC block groups if the
+MKE2FS_SYNC environment variable is set. This is to work around a VM
+bug in the 2.0 kernel. I've heard a report that a RAID user was able
+to trigger it even using a 2.2 kernel, but hopefully it will not be
+needed for most Linux 2.2 users.
+
+Fixed miscellaneous documentation and man pages.
+
+Programmer's notes:
+-------------------
+
+Cleaned up functions such as pass1_get_blocks, pass1_read_inode which
+in e2fsck's pass1.c really should have been static.
+
+The return value of the uuid_compare() function was changed to make it
+match with the convetions used by strcmp, memcmp, and Paul Leach's
+UUID sample document.
+
+The "make depend" process has now been made more automated; it now
+automatically word-wraps the dependencies, and only replaces source
+Makefile.in if there has been a change in the dependencies. Also, a
+top-level "make depend" now recurses through all the subdirectories
+automatically.
+
+The Makefile in .../util has been changed so that subst is built using
+the native C compiler during a cross-compilation, since the subst
+program is only used during the build process. Also add an explicit
+rule to build util/subst by cd'ing to the correct directory and
+running Makefile.
+
+The man directories are defined in terms mandir, so that the configure
+script can override the location of the manual pages.
+
+The config files have been updated to recognize new machine types for
+both the i386 and alpha families.
+
+Fsck has been modified so that it will accurately create an
+fsck_instance even when the noexecute flag is set. This allows for
+accurate debugging of the fsck pass structure. Also, when the verbose
+flag is given twice, fsck will print debugging information about when
+fsck is waiting for jobs to finish.
+
+
+E2fsprogs 1.14 (January 9, 1999)
+================================
+
+Fix the fstab parsing code so that it can handle blank lines and
+comment characters. Also, missing pass numbers need to be treated as
+zero.
+
+Fixed a bug in e2fsck where under some circumstances (when e2fsck
+needs to restart processing after fixing an egregious inconsistency)
+it would try to access already freed memory.
+
+E2fsck now prints non-printable characters in directory entries and
+pathnames using '^' and 'M-' notation.
+
+Fixed chattr so that it will ignore symbolic links when doing
+recursive descent traversals. For both chattr and lsattr, no longer
+print the version string unless the -V option is given.
+
+Allow the system administrator to directly specify the number of
+inodes desired in the filesystem, for some special cases where this is
+necessary.
+
+Fix portability problems so that e2fsprogs can be compiled under Linux
+1.2 systems and Solaris systems.
+
+Update the config.guess file with a more recent version that will
+identify newer Linux platforms.
+
+Programmer's notes
+------------------
+
+Ext2fs_read_inode and ext2fs_write_inode will now return an error if
+an inode number of zero is passed to them.
+
+E2fsprogs 1.13 (December 15, 1998)
+==================================
+
+Fixed a bug in debugfs where an error messages weren't getting printed
+when the ext2 library routines to read inodes returned errors in the
+stat, cmri and rm commands.
+
+Fixed a bug in mke2fs so that if a ridiculous inode ratio parameter is
+provided, it won't create an inode table smaller than the minimum
+number of inodes required for a proper ext2 filesystem.
+
+Fsck now parses the /etc/fstab file directly (instead of using
+getmntent()), so that it can distinguish between a missing pass number
+field and pass number field of zero. This caused problems for
+diskless workstations where all of the filesystems in /etc/fstab have
+an explicit pass number of zero, and fsck could not distinguish this
+from a /etc/fstab file with missing pass numbers.
+
+E2fsck will create a /lost+found directory if there isn't one in the
+filesystem, since it's safer to create the lost+found directory before
+it's needed.
+
+Fixed e2fsck so that it would detect bogus immutable inodes which
+happen to be sockets and FIFO files, and offer to clear them.
+
+If a filesystem has multiple reasons why it needs to be checked, and
+one of the reasons is that it is uncleanly mounted, e2fsck will print
+that as the reason why the filesystem is being checked.
+
+Cleaned up the output routines of mke2fs so that it doesn't overflow
+an 80 column display when formating really big filesystems.
+
+Added a sanity check to e2fsck to make sure that file descriptors 0,
+1, 2 are open before opening the hard disk. This avoids a problem
+where a broken program might exec e2fsck with those file descriptors
+closed, which would cause disastrous results if the kernel returns a
+file descriptor for the block device which is also used by FILE *
+stdout.
+
+Fixed up the e2fsck progress reporting functions so that the values
+reliably reach 100% at the completion of all of the e2fsck passes.
+
+Fixed minor documentation bugs in man pages and usage messages.
+
+Programmer's notes:
+-------------------
+
+Fixed a number of lint warnings in the ext2fs library and potential
+portability problems from other OS's header files that might define
+CPP macros for names like "max" and "min".
+
+ext2fs_badblocks_list_add() has been made more efficient when it needs
+to grow the bad blocks list.
+
+Fixed a bug in e2fsck which caused it to dereference a freed pointer
+just before exiting.
+
+Fixed the substition process for generating the mk_cmds and compile_et
+scripts so that they will work outside of the build tree.
+
+Add sanity check to e2fsck so that if an internal routine
+(ext2fs_get_dir_info) returns NULL, avoid dereferencing the pointer
+and causing a core dump. This should never happen, but...
+
+E2fsprogs 1.12 (July 9, 1998)
+==================================
+
+E2fsprogs now works with glibc (at least with the version shipped wtih
+RedHat 5.0). The ext2fs_llseek() function should now work even with
+i386 ELF shared libraries and if llseek() is not present. We also
+explicitly do a configure test to see if (a) llseek is in libc, and
+(b) if llseek is declared in the system header files. (See standard
+complaints about libc developers don't understand the concept of
+compatibility with previous versions of libc.)
+
+The ext2fs library now writes out the block group number in each of
+the superblock copies. This makes it easier to automatically
+determine the starting block group of the filesystem when the block
+group information is trashed.
+
+Added support for the EXT2_FEATURE_INCOMPAT_FILETYPE feature,
+which means that e2fsprogs will ignore the high 8 bits of the
+directory entry's name_len field, so that it can be used for other
+purposes.
+
+Added support for the EXT2_FEATURE_RO_COMPAT_LARGE_FILE feature.
+E2fsprogs will now support filesystems with 64-bit sized files.
+
+Added support for the EXT2_FEATURE_COMPAT_DIR_PREALLOC feature.
+
+Added new program "e2label", contributed by Andries Brouwer. E2label
+provides an easy-to-use interface to modify the filesystem label.
+
+Fixed bug so that lsattr -v works instead of producing a core dump.
+
+Fixed a minor bug in mke2fs so that all groups with bad superblock
+backup blocks are printed (not just the first one).
+
+Mke2fs will check the size of the device, and if the user specifies a
+filesystem size larger than the apparent size of the device it will
+print a warning message and ask if the user wants to proceed.
+
+E2fsck has a new option -C, which sends completion information to the
+specified file descriptor. For the most part, this is intended for
+programs to use, although -C 0 will print a spinning character to the
+stdout device, which may be useful for users who want to see something
+happening while e2fsck goes about its business.
+
+Fixed a bug in e2fsck which could cause a core dump when it needs to
+expand the /lost+found directory, and sometimes the bitmaps haven't
+been merged in. Also fixed a related bug where ext2fs_write_dir_block
+was used to write out a non-directory block. (Which would be bad on a
+non-Intel platform with byte swapping going on.)
+
+Fixed bug in e2fsck where it would print a "programming error" message
+instead of correctly identifying where a bad block was in used when
+the bad block was in a non-primary superblock or block group
+descriptor. Also fixed a related bug when sparse superblocks are in
+use and there is a bad block where a superblock or block group
+descriptor would have been in a group that doesn't include a
+superblock.
+
+Fixed a bug in e2fsck (really in libext2fs's dblist function) where if
+the block group descriptor table is corrupt, it was possible to try to
+allocate a huge array, fail, and then abort e2fsck.
+ext2fs_get_num_dirs() now sanity checks the block group descriptor,
+and subsitutes reasonable values if the descriptors are obviously bogus.
+
+If e2fsck finds a device file which has the immutable flag set and the
+i_blocks beyond the normal device number are non-zero, e2fsck will
+offer to remove it, since it's probably caused by garbage in the inode
+table.
+
+When opening a filesystem, e2fsck specially checks for the EROFS error
+code, and prints a specific error message to the user which is more
+user friendly.
+
+If the filesystem revision is too high, change the e2fsck to print
+that this is either because e2fsck is out of date, or because the
+superblock is corrupt.
+
+E2fsck now checks for directories that have duplicate '.' and '..'
+entries, and fixes this corruption.
+
+E2fsck no longer forces a sync of the filesystem (with attendant sleep
+calls) at all times. The ext2fs_flush() function now performs a sync
+only if it needed to write data blocks to disk.
+
+Fixed a minor bug in e2fsck's pass1b's file cloning function, where
+certain errors would not be properly reported.
+
+Updated and expanded a few points in the man pages which users
+complained wheren't explicit enough.
+
+Added special case byte-swapping code if compiling on the PowerPC, to
+accomodate the strange big-endian variant of the ext2 filesystem that
+was previously used on the PowerPC port.
+
+
+Programmer's notes:
+-------------------
+
+Removed C++ keywords from the ext2fs libraries so that it could be
+compiled with C++.
+
+E2fsck's internal organization has now been massively reorganized so
+that pass*.c don't have any printf statements. Instead, all problems
+are reported through the fix_problem() abstraction interface. E2fsck
+has also been revamped so that it can be called as a library from a
+application.
+
+Added new fileio primitives in libext2fs for reading and writing
+files on an unmounted ext2 filesystem. This interface is now used by
+debugfs.
+
+Added a new libext2fs function for mapping logical block numbers of
+a file to a physical block number.
+
+Added a new libext2fs function, ext2fs_alloc_block(), which allocates
+a block, zeros it, and updates the filesystem accounting records
+appropriately.
+
+Added a new libext2fs function, ext2fs_set_bitmap_padding(), which
+sets the padding of the bitmap to be all one's. Used by e2fsck pass 5.
+
+The libext2fs functions now use a set of memory allocation wrapper
+functions: ext2fs_get_mem, ext2fs_free_mem, and ext2fs_resize_mem,
+instead of malloc, free, and resize. This makes it easier for us to
+be ported to strange environments where malloc, et. al. aren't
+necessarily available.
+
+Change the libext2fs fucntion to return ext2-specific error codes
+(EXT2_DIR_EXISTS and EXT2_DB_NOT_FOUND, for example) instead of using
+and depending on the existence of system error codes (such as EEXIST
+and ENOENT).
+
+Renamed io.h to ext2_io.h to avoid collision with other OS's header
+files.
+
+Add protection against ext2_io.h and ext2fs.h being included multiple
+times.
+
+The types used for memory lengths, etc. have been made more portable.
+In generla, the code has been made 16-bit safe. Added Mark
+Habersack's contributed DOS disk i/o routines.
+
+Miscellaneous portability fixes, including not depending on char's
+being signed.
+
+The io_channel structure has a new element, app_data, which is
+initialized by the ext2fs routines to contain a copy of the filesystem
+handle.
+
+ext2fs_check_directory()'s callback function may now return the error
+EXT2_ET_CALLBACK_NOTHANDLED if it wishes ext2fs_check_directory() to
+really do the checking, despite the presence of the callback function.
+
+
+E2fsprosg 1.11 (June 17, 1997)
+==============================
+
+Fixed e2fsck to detect (previously ignored) conflicts between the
+superblock or block group descriptors and block bitmaps, inode
+bitmaps, and inode tables.
+
+Fixed bug in e2fsck so that when the message printed out when a block
+or inode bitmap conflicts with other data, it has the correct group
+number.
+
+Fixed bug in e2fsck and mke2fs where the blocksize wasn't being passed
+to badblocks. This meant that not all of the filesystem was being
+tested for bad blocks!
+
+Fixed an array boundary overrun case which cropped up in
+ext2fs_badblocks_list_test when a user tried running "mke2fs -c
+-b 4096".
+
+Adjusted the number of columns printed by mke2fs when displaying the
+superblock backups to avoid running over 80 columns when making a
+really big filesystem.
+
+Fixed up the man pages for e2fsck, debugfs, badblocks, chattr,
+dumpe2fs, fsck, mke2fs, and tune2fs (typos and other minor grammar
+fixes), thanks to some suggestions from Bill Hawes (whawes@star.net).
+
+Programmer's notes:
+-------------------
+
+Fixed install rule in lib/ss so that ss_err.h is actually getting
+installed.
+
+Fixed bug in ext2fs_copy_bitmap; the destination bitmap wasn't getting
+bassed back to the caller.
+
+Fixed bug in ext2fs_inode_scan_goto_blockgroup; it had not been
+setting the current inode number (which meant this function wasn't
+working at all).
+
+Fixed bug in ext2fs_resize_generic_bitmap; it had not be zeroing all
+blocks in the bitmap when increasing the size of the bitmap.
+
+Changed the initial number of blocks allocated by ext2fs_init_dblist()
+to be more realistic.
+
+Added a new function ext2fs_allocate_group_table, which sets up the
+group descriptor information (and allocates inode and block bitmaps,
+and inode tables for a particular group). The function was created by
+factoring out code form ext2fs_allocate_tables().
+
+Added a new function ext2fs_move_blocks which takes a bitmap of the
+blocks to be moved, and moves them to another location on the
+boardboard.
+
+Make the unix_io channel's io_channel_flush implementation calls sync()
+to to flush the kernel buffers to disk.
+
+Added a new function ext2fs_dblist_count returns the number of
+directory blocks in dblist.
+
+
+E2fsprogs 1.10 (April 24, 1997)
+===============================
+
+Mke2fs once again defaults to creating revision #0 filesystems, since
+people were complaining about breaking compatibility with 1.2 kernels.
+Warning messages were added to the mke2fs and tune2fs man pages that
+the sparse superblock option isn't supported by most kernels yet (1.2
+and 2.0 both don't support parse superblocks.)
+
+Added new flag to mke2fs, -R <raid options>, which allows the user to
+tell mke2fs about the RAID configuration of the filesystem. Currently
+the only supported raid option is "stride" which specifies the width
+of the RAID stripe.
+
+Fixed bug in e2fsck where pass1b would bomb out if there were any
+blocks marked bad in the inode table.
+
+Fixed rare bug in mke2fs where if the user had a very unlucky number
+of blocks in a filesystem (probability less than .002) the resulting
+filesystem would be corrupt in the last block group.
+
+Fixed bug where if e2fsck tried to allocate a block to fix a
+filesystem corruption problem and the filesystem had no free blocks,
+ext2fs_new_block() would loop forever.
+
+The configure script now checks explicitly to see if "-static" works,
+since that can't be assumed to be true --- RedHat doesn't install
+libc-static by default.
+
+Fixed bug in libext2's block iterator functions where under some
+cirmcustances, file with holes would cause the bcount parameter to the
+callback function to be incorrect. This bug didn't affect any of
+e2fsprogs programs, but it was discovered by Paul Mackerras, the
+author of the PPC boot loader.
+
+Removed use of static variables to store the inode cache in libext2fs.
+This caused problems if more than one filesystem was accessed via
+libext2fs (static variables in libraries are generally a bad idea).
+Again, this didn't affect e2fsprogs programs, but it was discovered by
+Paul Mackerras.
+
+Fixed minor bugs and version code drift to assure that e2fsprogs 1.10
+will compile cleanly with 1.2.13 kernels (even with a.out shared
+libraries!)
+
+Programmer's notes:
+-------------------
+
+Added new functions to duplicate an ext2 filesystem handle, and its
+associated substructure. New functions: ext2fs_dup_handle(),
+ext2fs_copy_dblist(), ext2fs_badblocks_copy(), ext2fs_copy_bitmap().
+Other structures, such as the io_channel and the inode_cache, now have
+a ref count so that they only get freed when they are no longer used
+by any filesystem handle. (These functions were added as part of the
+development effort for an ext2 resizer).
+
+E2fsprogs 1.09 (April 14, 1997)
+===============================
+
+Fixed bug in mke2fs (really in lib/ext2fs/initialize.c) which was
+accidentally introduced in the 1.08 release. The overhead calculation
+was accidentally removed, which caused ext2fs_initialize() to not
+notice when the filesystem size needed to be adjusted down because
+there wasn't enough space in the last block group.
+
+Fixed bug in version parsing library routine; it was always parsing
+the library version string, instead of using the passed-in string.
+
+Clarified chattr man page.
+
+E2fsprogs 1.08 (April 10, 1997)
+===============================
+
+E2fsck 1.07 was very slow when checking very large filesystems with a
+lot of files that had hard links (i.e., news spools). This was fixed
+by seriously revamping the icount abstraction. Added a formal test
+suite for the icount abstraction.
+
+Debugfs now has a "-l" option to the "ls" command, which lists the
+inode number, permissions, owner, group, size, and name of the files
+in the directory.
+
+Fix a bug in e2fsck where when a directory had its blocks moved to
+another location during the pass 1b processing, the directory block
+list wasn't updated, so pass 2 wouldn't check (and correct) the
+correct directory block.
+
+E2fsck will now treat inodes which contain blocks which are claimed by
+the filesystem metadata by treating them as multiply claimed blocks.
+This way, the data in those blocks can be copied to a new block during
+the pass 1b--1d processing.
+
+E2fsck will attempt to determine the correct superblock number and
+display it in the diagnostic and warning messages if possible.
+
+Add support for a new (incompatible) feature, "sparse_super". This
+feature reduces the number of blocks which contain copies of backup
+superblocks and block group descriptors. (It is only an incompatible
+feature because of a bug in ext2_free_blocks.) mke2fs and tune2fs now
+support a new -s option; e2fsck will recognize filesystems built with
+this feature turned on.
+
+E2fsck now checks the library to make sure is the correct version,
+using new library functions. (This helps to diagnose incorrectly
+installed e2fsprogs distributions.)
+
+Dumpe2fs now prints more information; its now prints the the
+filesystem revision number, the filesystem sparse_super feature (if
+present), the block ranges for each block group, and the offset from
+the beginning of the block group.
+
+Mke2fs now distributes the inode and block bitmap blok so that the
+won't be concentrated in one or two disks in RAID/striping setups.
+Also, if the user chooses a 2k or 4k block group, mke2fs will try to
+choose the largest blocks per group that be chosen. (For 2k blocks,
+you can have up to 16384 blocks/group; for 4k blocks, you can have up
+to 32768 blocks/group.) Previously mke2fs would not allow
+specification of more than 8192 blocks per group, even if you were
+using a 2k or 4k block group.
+
+Programmer's notes:
+-------------------
+
+Added a new function ext2fs_create_icount2() which takes a "hint"
+argument. This hint argument presets the icount array with the list
+of inodes which actually need to be in the icount array. This really
+helps to speed up e2fsck.
+
+Added a new function ext2fs_icount_validate() which checks the rep
+invariant for the icount structure. This is used mostly for testing.
+
+The error mesasage given when a bad inode number is passed to
+test_generic_bitmap to reflect EXT2FS_TEST_ERROR (instead of
+EXT2FS_UNMARK_ERROR).
+
+Added a new function ext2fs_set_dir_block which sets the block of a
+dblist entry, given the directory inode and blockcnt.
+
+Added a new function ext2fs_get_library_version() which returns the
+current library version, and ext2fs_parse_version_string() which
+returns a version number based on a e2fsprogs version string.
+
+The icount functions will return EINVAL if the passed in inode number
+is out of bounds.
+
+E2fsprogs 1.07 (March 9, 1997)
+==============================
+
+E2fsck is now uses much less memory when checking really large
+filesystems (or rather, filesystems with a large number of inodes).
+Previously a filesystem with 1 million inodes required 4 megabytes of
+memory to store inode count statistics; that storage requirement has
+now been reduced to roughly half a megabyte.
+
+E2fsck can now properly deal with bad blocks appearing inside the
+inode table. Instead of trying to relocate the inode table (which
+often failed because there wasn't enough space), the inodes in the bad
+block are marked as in use.
+
+E2fsck will automatically try to use the backup superblocks if the
+primary superblocks have a bad magic number or have missing meta-data
+blocks (or meta-data blocks which are out of range).
+
+E2fsck's pass 3 has been made more efficient; most noticeable on
+filesystems with a very large number of directories.
+
+Completely revamped e2fsck's system of printing problem reports. It
+is now table driven, to make them more easily customizeable and
+extendable. Error messages which can be printed out during preen mode
+are now one line long.
+
+Fixed e2fsck's filesystem swapping code so that it won't try to swap
+fast symbolic links or deleted files.
+
+Fixed e2fsck core dumping when fixing a filesystem which has no
+directories (not even a root directory).
+
+Added a check to e2fsck to make sure that the length of every
+directory entry is a multiple of 4 (since the kernel complains if it
+isn't).
+
+Added a check to e2fsck to make sure that a directory entry isn't a
+link to the root directory, since that isn't allowed.
+
+Added a check to e2fsk to now make sure the '.' and '..' directory
+entries are null terminated, since the 2.0 kernel requires it.
+
+Added check to write_bitmaps() to make sure the superblock doesn't get
+trashed if the inode or block bitmap is marked as being block zero.
+
+Added checking of the new feature set fields in the superblock, to
+avoid dealing with new filesystem features that this package wasn't
+set up to handle.
+
+Fixed a fencepost error in ext2fs_new_block() which would occasionally
+try to allocate a block beyond the end of a filesystem.
+
+When the UUID library picks a random IEEE 802 address (because it
+can't find one from a network card), it sets the multicast bit, to
+avoid conflicting with a legitimate IEEE 802 address.
+
+Mke2fs now sets the root directory's owner to be the real uid of the
+user running mke2fs. If the real uid is non-zero, it also sets
+the group ownership of the root directory to be the real group-id of
+the user running mke2fs.
+
+Mke2fs now has more intelligent error checking when it is given a
+non-existent device.
+
+When badblocks is given the -vv option, it now updates the block that
+it is currently testing on every block.
+
+Fixed a bug in fsck where it wouldn't modify the PATH envirnoment
+currently correctly if PATH wasn't already set.
+
+Shared libraries now built with dependencies. This allows the shared
+library files to be used with dlopen(); it also makes the transition
+to libc 6 easier, since ld.so can tell which libc a particular shared
+library expects to use.
+
+Programmer's notes:
+-------------------
+
+Added new abstraction (defined in dblist.c) for maintaining a list of
+blocks which belongs to directories. This is used in e2fsck and other
+programs which need to iterate over all directories.
+
+Added new functions which test to see if a contiguous range of blocks
+(or inodes) are available. (ext2fs_*_bitmap_range).
+
+Added new function (ext2_inode_has_valid_blocks) which returns true if
+an inode has valid blocks. (moved from e2fsck code).
+
+Added new function (ext2fs_allocate_tables) which allocates the
+meta-data blocks as part of initializing a filesystem. (moved from
+mke2fs code).
+
+Added a new I/O manager for testing purposes. It will either allow a
+program to intercept I/O requests, or print debugging messages to
+trace the activity of a program using the I/O manager.
+
+The badblocks_list functions now store the bad blocks in a sorted
+order, and use a binary search to speed up badblocks_list_test.
+
+The inode scan function ext2fs_get_next_inode() may now return a soft
+error returns: MISSING_INODE_TABLE and BAD_BLOCK_IN_INODE_TABLE in
+those cases where part of an inode table is missing or there is a bad
+block in the inode table.
+
+Added a new function (ext2fs_block_iterate2) which adds new arguments to
+the callback function to return a pointer (block and offset) to the
+reference of the block.
+
+Added new function (ext2fs_inode_scan_goto_blockgroup) which allows an
+application to jump to a particular block group while doing an inode
+scan.
+
+The badblocks list functions were renamed from badblocks_* to
+ext2fs_badblocks_*. Backwards compatibility functions are available
+for now, but programs should be modified to use the new interface.
+
+Some of the library functions were reorganized into separate files to
+reduce the size of some programs which statically link against the
+ext2 library.
+
+Put in some miscellaneous fixes for the Alpha platform.
+
+
+E2fsprogs 1.06 (October 7, 1996)
+================================
+
+Fixed serious bug in e2fsck: if the block descriptors are bad, don't
+smash the backup copies in ext2fs_close(). (The problem was that when
+e2fsck -p discovered the problem, while it was closing the filesystem
+and exiting, it was also blowing away the backup superblocks on the
+disk, which was less than friendly.) We now make it the case that we
+only write out the backup superblock and the back block descriptors if
+the filesystem is completely free from problems.
+
+Fixed a bug in block_interate in the lib/ext2fs library which caused
+e2fsck to fail on GNU Hurd-created filesystems.
+
+Add support for Linux/FT's bootloader, which actually uses
+EXT2_BOOT_LOADER, and sets its mode bits which caused e2fsck to want
+to clear the inode.
+
+Add support for the "A" (no atime update) attribute. (Note: this
+attribute is not yet in production kernels.)
+
+The test suite is not automatically run when doing a "make all" from
+the top level directory. Users should manually run "make check" if
+they wish to run the test suite.
+
+Upon a preenhalt(), make the printed message more explicit that
+running e2fsck "MANAULLY" means without the -p or -a options.
+
+In e2fsck, if a disconnected inode is zero-length, offer to clear it
+instead of offering to connect it to lost+found.
+
+In e2fsck, if a filesystem was just unmounted uncleanly, and needs
+e2fsck to be run over it, change e2fsck to explicitly display this
+fact.
+
+For dumpe2fs and e2fsck, cause the -V option to print out which
+version of the ext2fs library is actually getting used. (This will
+help detect mismatches of using a 1.06 utility with a 1.05 library,
+etc.)
+
+Programmers' notes:
+-------------------
+
+EXT2_SWAP_BYTES was changed to EXT2_FLAG_SWAP_BYTES, which better fits
+the naming convention.
+
+In ext2fs_initialize(), make sure the description for the inode bitmap
+is correctly initialize.
+
+Fixed minor type typo in ext2fs_allocate_generic_bitmap();
+
+E2fsprogs 1.05 (September 7, 1996)
+==================================
+
+Add support for new fields in the ext2 superblock --- volume name,
+volume UUID, and last mounted field. Dumpe2fs displays these fields,
+tune2fs and mke2fs allows you to set them. E2fsck will automatically
+generate a UUID for those volumes that don't have them.
+
+Put in support for e2fsck to recognize HURD specific ext2 features ---
+most notably, the translator block. The e2fsprogs tools will now use
+the creator_os field in the superblock to correctly handle different
+OS-specific variants of the ext2 filesystem.
+
+E2fsck now fixes inodes which have a the deletion time set, but which
+have a non-zero i_link_count field by offering to clear the deletion
+time. Previously e2fsck assumed that the inode was deleted (per 0.3c
+ext2 kernel behavior) and offered to unlink the file.
+
+If e2fsck sets the clean bit, but nothing else, set the exit code
+FSCK_NONDESTRUCT. After all, e2fsck did fix a filesystem error --- it
+set the filesystem valid bit when it was previously cleared. :-) This
+was needed to make the HURD fsck driver happy.
+
+If the user refuses to attach an unattached inode, e2fsck will no
+longer set the inode's link count. Otherwise, the inode would end up
+getting marked as unused, which might cause loss of data later.
+
+Make the message issued by e2fsck when the superblock is corrupt less
+confusing for users. It now mentions that another reason for the
+"corrupt superblock" message might be that the partition might not be
+an ext2 filesystem at all (it might swap, msdos filesystem, ufs, etc.)
+
+Make the libext2 library more robuest so that e2fsck won't coredump on
+an illegal superblock where the blocksize is zero. (f_crashdisk is
+the test case).
+
+By default, create filesystems where the default checkinterval is 6
+months (180 days). Linux servers can be robust enough that 20 reboots
+can be a long, long time.
+
+Added configure flag --enable-old-bitops, which forces the bitops to
+use the old (native) bitmask operations. By default on the sparc
+platform, the standard ext2 bit ordering is now used.
+
+Added a new feature to e2fsck to byte-swap filesystems; this can be
+used to convert old m68k filesystems to use the standard byte-order
+storage for the superblock, inodes, and directory blocks. This
+function is invoked by using the '-s' option to e2fsck.
+
+Debugfs's "dump" command has been enhanced so that it writes out the
+exact size of the file so that the nulls at the end of the file are
+eliminated. The command also accept a new "-p" option which will
+attempt preserve to preserve the ownernship, permissions, and
+file modification/access times.
+
+Debugfs has two new options, -f and -R. The -R option allows the user
+to execute a single debugfs command from the command line. The -f
+option allows the user to specify a "command file" containing debugfs
+commands which will get executed.
+
+Dumpe2fs now pretty prints the check interval, instead of just
+printing the check interval as a number of seconds.
+
+Fix bugs in debugfs: the params command when no filesystem is opened
+no longer causes a core dump. It is now possible to unlink a file
+when a pathame containing a '/' is specified.
+
+Tune2fs has a new -C option which sets the number of times the
+filesystem has been mounted.
+
+Fix the chattr '-v' option so that it actually works. Chattr was
+being buggy about the -v option parsing.
+
+Programmers' notes:
+-------------------
+
+The directory lib/uuid contains a set of library routines to generate
+DCE compatible UUIDs.
+
+Extended ext2fs_namei() to handle symbolic links. Added new function
+ext2fs_nami_follow() which will follow last symbolic link in the case
+where the pathname points to a sym link.
+
+The ext2fs_block_iterate function will now return the HURD translator
+block, if present. The new flag BLOCK_FLAG_DATA_ONLY will cause the
+iterator to return data blocks only. The ext2fs.h file now defines
+constants BLOCK_COUNT_IND, BLOCK_COUNT_DIND, BLOCK_COUNT_TIND, and
+BLOCK_COUNT_TRANSLATOR, which are the magic values passed in the block
+count field of the iterator callback function.
+
+The test script driver now takes an optional second argument, which is
+the test case to be run. This allows you to run a test case without
+needing to run the entire test suite.
+
+On Linux ELF systems, install the .so files in the correct places
+(/usr/lib). The .so files must be stored in the same directory as the
+.a files.
+
+Fixed miscellaneous HURD compilation issues with header file being
+included in the right order.
+
+Fixed debugfs so that it resets optind to zero, not one, since setting
+optind to zero is more correct.
+
+
+E2fsprogs 1.04 (May 16, 1996)
+=============================
+
+First "official" (1.03 was a limited release only) to support building
+e2fsprogs under Linux 2.0 kernels (as well as late model 1.3 and 1.99
+kernels).
+
+This package includes a RPM specs file, that it can be built using the
+RedHat Package Manager.
+
+E2fsck now prints a hint that if there are lots of incorrectly located
+inode bitmaps, block bitmaps, and inode table blocks, the user might
+want to try using e2fsck -b 8193 first, to see if that fares any
+better.
+
+For ext2 filesystem written with the hurd, debugfs will now print out
+the translator field when printing an inode structure.
+
+Lots of miscellaneous linking/installation cleanups:
+
+ Libraries are now linked using a relative pathname, instead of
+ relying on -L working correct. It doesn't, in many cases, including
+ current versions of GNU ld. This guarantees that the build tree is
+ linking with the right libraries, instead of the ones installed in
+ /usr/lib.
+
+ Header files, man pages, and the et/ss shell scripts are now
+ generated using a custom substitution script, instead of relying on
+ the configure script. This prevents needless recompilation of
+ files; in addition, the custom substitution script is much faster.
+
+ e2fsck may now be linked dynamically, by using the
+ --enable-dynamic-e2fsck flag to configure. This is not recommended,
+ since it increases e2fsck's dependence on other files, but some
+ people need to save disk space, and other critical programs on their
+ systems were being linked dynamically anyway.
+
+ Programs such as fsck which didn't need to be linked against
+ libext2fs (or mke2fs which didn't need to be linked against libe2p)
+ only link against libraries they actually need. Otherwise, those
+ programs would require the presense of libraries that otherwise
+ could be removed from a rescuse diskette.
+
+ The ss include files are now installed correctly so they can
+ actually be used by another package.
+
+ If the profiling libraries are built, they are now installed on a
+ "make install-libs".
+
+
+E2fsprogs 1.03 (March 27, 1996)
+===============================
+
+Change the m68k bit numbering for bitmasks to match the bit numbering
+used by all other ext2 implementations. (This change was requested by
+the m68k kernel development team.)
+
+Support (in-development) filesystem format revision which supports
+(among other things) dynamically sized inodes.
+
+Fixed a bug in the ext2 library so that an intelligent error is
+returned if mke2fs is run with a ridiculously small number of blocks
+for a partition.
+
+Fixed a bug in the ext2 library which required that the device be
+openable in read/write mode in order to determine its size. This
+caused e2fsck -n to require read/write access when it was not
+previously necessary.
+
+Fixed a bug in e2fsck which casued it to occasionally fail the test
+suite depending on which version of the floating point library it was
+using.
+
+Fixed a bug in e2fsck so that it now halts with a fatal error when
+certain superblock consistency checks fail. Previously it continued
+running e2fsck, with some potential confusing/damaging consequences.
+
+Added new flag to fsck which allows the root to be checked in parallel
+with other filesytems. This is not the safest thing in the world to
+do, but some system administrators really wanted it.
+
+Fixed -Wall flames in lib/ss.
+
+
+E2fsprogs 1.02 (January 16, 1996)
+=================================
+
+Fix to allow e2fsprogs to be compiled on recent 1.3 (pl45+) kernels.
+
+Change e2fsck to print statistics of how many non-contiguous files are
+on the system. Note that a file which is larger than 8k blocks, it is
+guaranteed to be non-contiguous.
+
+In mke2fs, print a warning message if a user tries to format a whole
+disk (/dev/hda versus /dev/hda1). If a user really wants to format a
+whole disk, the -F (force) option forces mke2fs to format a whole disk
+as a filesytem.
+
+Fix a bug in fsck where in some cases it might start checking
+partitions in the next pass before it finishes checking partitions in
+the current pass. This still won't cause two partitions on the same
+disk will be checked, so it's rarely a problem in real life.
+
+Patch lsattr so that it won't hang when checking a named pipe.
+
+Minor compilation fixes:
+ * Fix the order of libraries that were linked in debugfs.
+ * Allow the sources to be compiled with -ansi turned on.

+#
+# SYNOPSIS
+#
+# CHECK_GNU_MAKE()
+#
+# DESCRIPTION
+#
+# This macro searches for a GNU version of make. If a match is found, the
+# makefile variable `ifGNUmake' is set to the empty string, otherwise it
+# is set to "#". This is useful for including a special features in a
+# Makefile, which cannot be handled by other versions of make. The
+# variable _cv_gnu_make_command is set to the command to invoke GNU make
+# if it exists, the empty string otherwise.
+#
+# Here is an example of its use:
+#
+# Makefile.in might contain:
+#
+# # A failsafe way of putting a dependency rule into a makefile
+# $(DEPEND):
+# $(CC) -MM $(srcdir)/*.c > $(DEPEND)
+#
+# @ifGNUmake@ ifeq ($(DEPEND),$(wildcard $(DEPEND)))
+# @ifGNUmake@ include $(DEPEND)
+# @ifGNUmake@ endif
+#
+# Then configure.in would normally contain:
+#
+# CHECK_GNU_MAKE()
+# AC_OUTPUT(Makefile)
+#
+# Then perhaps to cause gnu make to override any other make, we could do
+# something like this (note that GNU make always looks for GNUmakefile
+# first):
+#
+# if ! test x$_cv_gnu_make_command = x ; then
+# mv Makefile GNUmakefile
+# echo .DEFAULT: > Makefile ;
+# echo \ $_cv_gnu_make_command \$@ >> Makefile;
+# fi
+#
+# Then, if any (well almost any) other make is called, and GNU make also
+# exists, then the other make wraps the GNU make.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl default (if it is not specified or empty) is 'no-libtool'.
+dnl INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl depending on --{enable,disable}-{shared,static} and on the presence of
+dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl implementations (in libc or libintl) without the ngettext() function
+dnl will be ignored. If NEEDSYMBOL is specified and is
+dnl 'need-formatstring-macros', then GNU gettext implementations that don't
+dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries. If empty,
+dnl the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl and used.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl Catalog format: none
+dnl Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ PKG_CONFIG path to pkg-config utility
+ PKG_CONFIG_PATH
+ directories to add to pkg-config's search path
+ PKG_CONFIG_LIBDIR
+ path overriding pkg-config's built-in search path
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+ mmap private fixed at somewhere currently unmapped
+ mmap private fixed at somewhere already mapped
+ mmap shared not fixed
+ mmap shared fixed at somewhere currently unmapped
+ mmap shared fixed at somewhere already mapped
+ For private mappings, we should verify that changes cannot be read()
+ back from the file, nor mmap's back from the file at a different
+ address. (There have been systems where private was not correctly
+ implemented like the infamous i386 svr4.0, and systems where the
+ VM page cache was not coherent with the file system buffer cache
+ like early versions of FreeBSD and possibly contemporary NetBSD.)
+ For shared mappings, we should conversely verify that changes get
+ propagated back to all the places they're supposed to be.
+
+ Grep wants private fixed already mapped.
+ The main things grep needs to know about mmap are:
+ * does it exist and is it safe to write into the mmap'd area
+ * how to use it (BSD variants) */

+Description: The headers and static libraries for ext2fs-aware tools-development.
+ EXT2FS stands for "Extended Filesystem", version 2. It's the filesystem
+ type used for hard disks on Debian and other Linux systems.
+ .
+ This package contains the headers and shared libraries needed to compile
+ ext2fs-aware programs. Only programmers that really manipulate
+ features specific to the ext2 filesystem will need this. Most
+ programmers will use the generic filesystem-independent interface
+ from libc.
+ .
+ It also contains dev files for 2 other libs (e2p and uuid) used by
+ the e2fsprogs, but which are not yet packaged all by themselves
+ because they lack documentation. They may also lack some support
+ files, by I can't really know until someone uses them...
+ .
+ libe2p is for user-level e2fsprogs commands. It's used by dumpe2fs,
+ chattr, and lsattr. Functions in libe2p typically have two
+ characteristics (a) don't require that block device containing the
+ filesystem be opened directly (functions in libext2fs do), and (b)
+ libe2p typically contains printf statements or parse user input, and so
+ have more internationalization issues.
+ .
+ libuuid generates and parses 128-bit universally unique id's (UUID's),
+ using a standard which is blessed by both Microsoft and DCE, and is
+ being proposed as an internet standard. See the internet-draft:
+ .
+ draft-leach-uuids-guids-01.txt
+ .
+ for more information.

+e2fsprogs (1.42.12-1) unstable; urgency=low
+
+ * New upstream version
+ * Fix various e2fsck bugs when trying to repair bigalloc file systems.
+ * E2fsck can now repair a file system with an overly large
+ s_first_meta_bg field, which had previously caused all e2fsprogs
+ programs to crash when trying to open such a file system.
+ * Fix e2fsck so that it can correctly fix a number of rare file system
+ corruptions that were discovered when using a file system fuzzer.
+ * Fix e2fsck so it does not try to write back block group descriptors
+ if they have not been modified.
+ * The mke2fs program will now place metadata blocks in the last
+ flex_bg so they are contiguous. This reduces free space
+ fragmentation in a freshly created file system, as well as allowing
+ mke2fs commands which request extremely large flex_bg size to succeed.
+ * Mke2fs now creates hugefiles more efficiently (with fewer extent
+ tree blocks).
+ * Fix a 32/64-bit overflow bug that could cause resize2fs to loop
+ forever.
+ * Reduce the memory consumption of resize2fs for very large file
+ systems.
+ * Fix a bug that could cause resize2fs to create a corrupted file
+ system when shrinking a very large file system (typically > 16TB)
+ that had been previously grown using resize2fs. (Closes: #756922)
+ * Fix tune2fs updating UUID's when manipulating file systems with
+ external journals (both the file system and journal UUID).
+ * Fix tune2fs so it can remove an external journal for file systems
+ with a 1k block size.
+ * Add a new debugfs command, "inode_dump", which prints the inode in
+ hex and ASCII format.
+ * The debugfs command "set_inode_field" will now automatically
+ allocate blocks for indirect blocks and extent tree blocks.
+ * Fix debugfs's "set_inode_field" so can properly handle
+ "block[IND|DIND|TIND]".
+ * The debugfs "rdump" command will now take multiple source arguments.
+ * Fix debugfs's argument parsing for the freefrag command.
+ * Fixed a double close(2) bug in "rdump" and "rdump -p".
+ * Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
+ * e4defrag will now defrag backwards-allocated files
+ * Clarified messages that were confusing users in debugfs, e2fsck,
+ mke2fs, and resize2fs (Closes: #758029, #757543, #757544)
+ * Dumpe2fs will now complain if extra arguments are given to it.
+ (Closes: #758074)
+ * Update/clarify various man pages (Closes: #726760)
+ * Update Czech, Dutch, French, Polish, Spanish, Sweedish, Ukrainian,
+ and Vietnamese translations

+ even on ext3 filesystems.

+ * Fix blkid's ntfs UUID handling so it is compatible with vol_id
+ * Avoid a floating point exception when blkid tries to probe a corrpt
+ reiserfs filesystem.

+ * E2fsck will no longer backup superblocks when the kernel makes
+ certain "safe" feature set changes behind the user's back.
+ * Fix debugfs's lsdel command so it works on large files
+ * Allow a user to undelete an inode with linking to a destination

+
+ * Make sure that programs like tune2fs, when modifying a mounted
+ filesystem do not write the backup superblocks with the
+ NEEDS_RECOVERY flag, to avoid e2fsck from needlessly forcing a
+ full fsck because it thinks the feature flags need to be backed up
+ from the master to the backup superblocks. (Closes: #454926)
+ * Improve time-based UUID generation to guarantee uniqueness even when
+ UUID's are being generated at very high rates on SMP systems. To
+ do this we use an optional setuid helper daemon (uuidd) which is
+ started by libuuid when it is needed. The uuidd daemon is
+ packaged in the (new) uuid-runtime package, which now also includes
+ the uuidgen program (which had been previously been included as
+ part of the e2fsprogs package).
+ * Fix fsck to only treat '#' characters at the beginning of /etc/fstab
+ lines as starting a comment. This avoids spurious warnings printed
+ for filesystems such as fuse that often use '#' as part of the
+ filesystem specifier (i.e., wdfs#https://dav.hoster.com/foo).
+ * Enhance the blkid program to pretty-print control and meta
+ characters to avoid garbage filesystem labels from screwing up the
+ user's terminal
+ * Fix potential integer overflows passed to malloc() in resize2fs
+ * Update Dutch, Polish, and Vietnamese translations from the
+ Translation Project. Remove the Rwandan translation upon advice
+ of the Translation Project.

+ (Closes: #451172, #437720)

+ choice for woody.
+
+ * New upstream release (Closes: #106622, #116975, #118443, #119624,
+ #120171, #120077, #129828, #132764).
+ ** Fixes for data-corruption bugs not reported to the BTS: e2fsck
+ trashed external journals needing to be replayed, e2fsck now hides
+ visible journal files (data corruption problems when not excluded from
+ a backup and then restored) (Closes: #132654).
+ ** Other noticable bugs fixed include: e2fsck null pointer
+ dereferencing, fsck did not finds LVM volumes by UUID or by label,
+ largefile support (ie. dealing with filesystems inside 2GB+ files) was
+ broken in several programs.
+ * Switch to debhelper v3 to get ldconfig automatically handled
+ (lintian reported that it was broken). Now call dh_makeshlibs, but
+ still override its generated shlibs file with ours, to get compiled
+ packages depend of the correct virtual packages, which include
+ full sonames.
+ * Removed call do dh_installman (Closes: #115526).
+ * Cleaned up maintainer scripts with dead code - most things are now
+ more properly handled by debhelper. Removed an "exit 0" lurking in
+ preinst - can't find a reason for it in the changelog, it was probably
+ here for ages.
+ * Remove obsolete maint-scripts in binary-arch, as they are provided by
+ upstream.
+ * Also remove upstream-shipped config.cache before configuring. That
+ shouldn't impact us, but well, that makes lintian happy :)

+In order to santize e2fsprogs to be DFSG free, the file
+draft-leach-uuids-guids-01.txt has been removed. It can be obtained
+by downloading e2fsprogs from the upstream sources. It may also be
+available from other sites on the network, if you do a quick web
+search for the string "draft-leach-uuids-guids-01".
+
+Note that debian/rules is set up to include the file on Ubuntu
+systems, so for people trying to build e2fsprogs on Ubuntu systems,
+they should start from the upstream sources, and not the
+Debian-expurgated sources found in the Debian repository. (n.b., for
+WIP releases the command "./util/gen-tarball ubuntu" will help create
+tar file which is appropriately named to make life easier for
+dpkg-buildpackage.) Since Ubuntu doesn't have the DFSG restrictions,
+the documentation which has been removed for Debian's DFSG license
+purity shouldn't be denied to Ubuntu users.

+.SH DESCRIPTION
+The
+.B debugfs
+program is an interactive file system debugger. It can be used to
+examine and change the state of an ext2, ext3, or ext4 file system.
+.br
+.I device
+is the special file corresponding to the device containing the
+file system (e.g /dev/hdXX).
+.SH OPTIONS
+.TP
+.I \-w
+Specifies that the file system should be opened in read-write mode.
+Without this option, the file system is opened in read-only mode.
+.TP
+.I \-c
+Specifies that the file system should be opened in catastrophic mode, in
+which the inode and group bitmaps are not read initially. This can be
+useful for filesystems with significant corruption, but because of this,
+catastrophic mode forces the filesystem to be opened read-only.
+.TP
+.I \-i
+Specifies that
+.I device
+represents an ext2 image file created by the
+.B e2image
+program. Since the ext2 image file only contains the superblock, block
+group descriptor, block and inode allocation bitmaps, and
+the inode table, many
+.B debugfs
+commands will not function properly.
+.B Warning:
+no safety checks are in place, and
+.B debugfs
+may fail in interesting ways if commands such as
+.IR ls ", " dump ", "
+etc. are tried without specifying the
+.I data_source_device
+using the
+.I \-d
+option.
+.B debugfs
+is a debugging tool. It has rough edges!
+.TP
+.I -d data_source_device
+Used with the
+.I \-i
+option, specifies that
+.I data_source_device
+should be used when reading blocks not found in the ext2 image file.
+This includes data, directory, and indirect blocks.
+.TP
+.I -b blocksize
+Forces the use of the given block size for the file system, rather than
+detecting the correct block size as normal.
+.TP
+.I -s superblock
+Causes the file system superblock to be read from the given block
+number, instead of using the primary superblock (located at an offset of
+1024 bytes from the beginning of the filesystem). If you specify the
+.I -s
+option, you must also provide the blocksize of the filesystem via the
+.I -b
+option.
+.TP
+.I -f cmd_file
+Causes
+.B debugfs
+to read in commands from
+.IR cmd_file ,
+and execute them. When
+.B debugfs
+is finished executing those commands, it will exit.
+.TP
+.I -D
+Causes
+.B debugfs
+to open the device using Direct I/O, bypassing the buffer cache. Note
+that some Linux devices, notably device mapper as of this writing, do
+not support Direct I/O.
+.TP
+.I -R request
+Causes
+.B debugfs
+to execute the single command
+.IR request ,
+and then exit.
+.TP
+.I -V
+print the version number of
+.B debugfs
+and exit.
+.SH SPECIFYING FILES
+Many
+.B debugfs
+commands take a
+.I filespec
+as an argument to specify an inode (as opposed to a pathname)
+in the filesystem which is currently opened by
+.BR debugfs .
+The
+.I filespec
+argument may be specified in two forms. The first form is an inode
+number surrounded by angle brackets, e.g.,
+.IR <2> .
+The second form is a pathname; if the pathname is prefixed by a forward slash
+('/'), then it is interpreted relative to the root of the filesystem
+which is currently opened by
+.BR debugfs .
+If not, the pathname is
+interpreted relative to the current working directory as maintained by
+.BR debugfs .
+This may be modified by using the
+.B debugfs
+command
+.IR cd .
+.\"
+.\"
+.\"
+.SH COMMANDS
+This is a list of the commands which
+.B debugfs
+supports.
+.TP
+.BI blocks " filespace"
+Print the blocks used by the inode
+.I filespec
+to stdout.
+.TP
+.BI bmap " filespec logical_block"
+Print the physical block number corresponding to the logical block number
+.I logical_block
+in the inode
+.IR filespec .
+.TP
+.BI block_dump " [-f filespec] block_num"
+Dump the filesystem block given by
+.I block_num
+in hex and ASCII format to the console. If the
+.I -f
+option is specified, the block number is relative to the start of the given
+.BR filespec .
+.TP
+.BI cat " filespec"
+Dump the contents of the inode
+.I filespec
+to stdout.
+.TP
+.BI cd " filespec"
+Change the current working directory to
+.IR filespec .
+.TP
+.BI chroot " filespec"
+Change the root directory to be the directory
+.IR filespec .
+.TP
+.BI close " [-a]"
+Close the currently open file system. If the
+.I -a
+option is specified, write out any changes to the superblock and block
+group descriptors to all of the backup superblocks, not just to the
+master superblock.
+.TP
+.BI clri " filespec"
+Clear the contents of the inode
+.IR filespec .
+.TP
+.BI dirsearch " filespec filename"
+Search the directory
+.I filespec
+for
+.IR filename .
+.TP
+.B dirty
+Mark the filesystem as dirty, so that the superblocks will be written on exit.
+.TP
+.BI dump " [-p] filespec out_file"
+Dump the contents of the inode
+.I filespec
+to the output file
+.IR out_file .
+If the
+.I -p
+option is given set the owner, group and permissions information on
+.I out_file
+to match
+.IR filespec .
+.TP
+.B dump_mmp
+Display the multiple-mount protection (mmp) field values.
+.TP
+.BI dx_hash " [-h hash_alg] [-s hash_seed] filename"
+Calculate the directory hash of
+.IR filename .
+The hash algorithm specified with
+.I -h
+may be
+.BR legacy , " half_md4" ", or " tea .
+The hash seed specified with
+.I -s
+must be in UUID format.
+.TP
+.BI dump_extents " [-n] [-l] filespec"
+Dump the the extent tree of the inode
+.IR filespec .
+The
+.I -n
+flag will cause
+.B dump_extents
+to only display the interior nodes in the extent tree. The
+.I -l
+flag will cause
+.B dump_extents
+to only display the leaf nodes in the extent tree.
+.IP
+(Please note that the length and range of blocks for the last extent in
+an interior node is an estimate by the extents library functions, and is
+not stored in filesystem data structures. Hence, the values displayed
+may not necessarily by accurate and does not indicate a problem or
+corruption in the file system.)
+.TP
+.BI expand_dir " filespec"
+Expand the directory
+.IR filespec .
+.TP
+.BI feature " [fs_feature] [-fs_feature] ..."
+Set or clear various filesystem features in the superblock. After setting
+or clearing any filesystem features that were requested, print the current
+state of the filesystem feature set.
+.TP
+.BI filefrag " [-dvr] filespec"
+Print the number of contiguous extents in
+.IR filespec .
+If
+.I filespec
+is a directory and the
+.I -d
+option is not specified,
+.I filefrag
+will print the number of contiguous extents for each file in
+the directory. The
+.I -v
+option will cause
+.I filefrag
+print a tabular listing of the contiguous extents in the
+file. The
+.I -r
+option will cause
+.I filefrag
+to do a recursive listing of the directory.
+.TP
+.BI find_free_block " [count [goal]]"
+Find the first
+.I count
+free blocks, starting from
+.I goal
+and allocate it. Also available as
+.BR ffb .
+.TP
+.BI find_free_inode " [dir [mode]]"
+Find a free inode and allocate it. If present,
+.I dir
+specifies the inode number of the directory
+which the inode is to be located. The second
+optional argument
+.I mode
+specifies the permissions of the new inode. (If the directory bit is set
+on the mode, the allocation routine will function differently.) Also
+available as
+.BR ffi .
+.TP
+.BI freeb " block [count]"
+Mark the block number
+.I block
+as not allocated.
+If the optional argument
+.I count
+is present, then
+.I count
+blocks starting at block number
+.I block
+will be marked as not allocated.
+.TP
+.BI freefrag " [-c chunk_kb]"
+Report free space fragmentation on the currently open file system.
+If the
+.I \-c
+option is specified then the filefrag command will print how many free
+chunks of size
+.I chunk_kb
+can be found in the file system. The chunk size must be a power of two
+and be larger than the file system block size.
+.TP
+.BI freei " filespec [num]"
+Free the inode specified by
+.IR filespec .
+If
+.I num
+is specified, also clear num-1 inodes after the specified inode.
+.TP
+.B help
+Print a list of commands understood by
+.BR debugfs .
+.TP
+.BI htree_dump " filespec"
+Dump the hash-indexed directory
+.IR filespec ,
+showing its tree structure.
+.TP
+.BI icheck " block ..."
+Print a listing of the inodes which use the one or more blocks specified
+on the command line.
+.TP
+.BI inode_dump " filespec"
+Print the contents of the inode data structure in hex and ASCII format.
+.TP
+.BI imap " filespec"
+Print the location of the inode data structure (in the inode table)
+of the inode
+.IR filespec .
+.TP
+.BI init_filesys " device blocksize"
+Create an ext2 file system on
+.I device
+with device size
+.IR blocksize .
+Note that this does not fully initialize all of the data structures;
+to do this, use the
+.BR mke2fs (8)
+program. This is just a call to the low-level library, which sets up
+the superblock and block descriptors.
+.TP
+.BI kill_file " filespec"
+Deallocate the inode
+.I filespec
+and its blocks. Note that this does not remove any directory
+entries (if any) to this inode. See the
+.BR rm (1)
+command if you wish to unlink a file.
+.TP
+.BI lcd " directory"
+Change the current working directory of the
+.B debugfs
+process to
+.I directory
+on the native filesystem.
+.TP
+.BI ln " filespec dest_file"
+Create a link named
+.I dest_file
+which is a hard link to
+.IR filespec .
+Note this does not adjust the inode reference counts.
+.TP
+.BI logdump " [-acs] [-b block] [-i filespec] [-f journal_file] [output_file]"
+Dump the contents of the ext3 journal. By default, dump the journal inode as
+specified in the superblock. However, this can be overridden with the
+.I \-i
+option, which dumps the journal from the internal inode given by
+.IR filespec .
+A regular file containing journal data can be specified using the
+.I \-f
+option. Finally, the
+.I \-s
+option utilizes the backup information in the superblock to locate the
+journal.
+.IP
+The
+.I \-a
+option causes the
+.B logdump
+program to print the contents of all of the descriptor blocks.
+The
+.I \-b
+option causes
+.B logdump
+to print all journal records that are refer to the specified block.
+The
+.I \-c
+option will print out the contents of all of the data blocks selected by
+the
+.I \-a
+and
+.I \-b
+options.
+.TP
+.BI ls " [-d] [-l] [-p] filespec"
+Print a listing of the files in the directory
+.IR filespec .
+The
+.I \-d
+flag will list deleted entries in the directory.
+The
+.I \-l
+flag will list files using a more verbose format.
+The
+.I \-p
+flag will list the files in a format which is more easily parsable by
+scripts, as well as making it more clear when there are spaces or other
+non-printing characters at the end of filenames.
+.TP
+.BI list_deleted_inodes " [limit]"
+List deleted inodes, optionally limited to those deleted within
+.I limit
+seconds ago. Also available as
+.BR lsdel .
+.IP
+This command was useful for recovering from accidental file deletions
+for ext2 file systems. Unfortunately, it is not useful for this purpose
+if the files were deleted using ext3 or ext4, since the inode's
+data blocks are no longer available after the inode is released.
+.TP
+.BI modify_inode " filespec"
+Modify the contents of the inode structure in the inode
+.IR filespec .
+Also available as
+.BR mi .
+.TP
+.BI mkdir " filespec"
+Make a directory.
+.TP
+.BI mknod " filespec [p|[[c|b] major minor]]"
+Create a special device file (a named pipe, character or block device).
+If a character or block device is to be made, the
+.I major
+and
+.I minor
+device numbers must be specified.
+.TP
+.BI ncheck " [-c] inode_num ..."
+Take the requested list of inode numbers, and print a listing of pathnames
+to those inodes. The
+.I -c
+flag will enable checking the file type information in the directory
+entry to make sure it matches the inode's type.
+.TP
+.BI open " [-weficD] [-b blocksize] [-s superblock] device"
+Open a filesystem for editing. The
+.I -f
+flag forces the filesystem to be opened even if there are some unknown
+or incompatible filesystem features which would normally
+prevent the filesystem from being opened. The
+.I -e
+flag causes the filesystem to be opened in exclusive mode. The
+.IR -b ", " -c ", " -i ", " -s ", " -w ", and " -D
+options behave the same as the command-line options to
+.BR debugfs .
+.TP
+.BI punch " filespec start_blk [end_blk]"
+Delete the blocks in the inode ranging from
+.I start_blk
+to
+.IR end_blk .
+If
+.I end_blk
+is omitted then this command will function as a truncate command; that
+is, all of the blocks starting at
+.I start_blk
+through to the end of the file will be deallocated.
+.TP
+.BI symlink " filespec target"
+Make a symbolic link.
+.TP
+.B pwd
+Print the current working directory.
+.TP
+.B quit
+Quit
+.B debugfs
+.TP
+.BI rdump " directory[...] destination"
+Recursively dump
+.IR directory ,
+or multiple
+.IR directories ,
+and all its contents (including regular files, symbolic links, and other
+directories) into the named
+.IR destination ,
+which should be an existing directory on the native filesystem.
+.TP
+.BI rm " pathname"
+Unlink
+.IR pathname .
+If this causes the inode pointed to by
+.I pathname
+to have no other references, deallocate the file. This command functions
+as the unlink() system call.
+.I
+.TP
+.BI rmdir " filespec"
+Remove the directory
+.IR filespec .
+.TP
+.BI setb " block [count]"
+Mark the block number
+.I block
+as allocated.
+If the optional argument
+.I count
+is present, then
+.I count
+blocks starting at block number
+.I block
+will be marked as allocated.
+.TP
+.BI set_block_group " bgnum field value"
+Modify the block group descriptor specified by
+.I bgnum
+so that the block group descriptor field
+.I field
+has value
+.IR value .
+Also available as
+.BR set_bg .
+.TP
+.BI seti " filespec [num]"
+Mark inode
+.I filespec
+as in use in the inode bitmap. If
+.I num
+is specified, also set num-1 inodes after the specified inode.
+.TP
+.BI set_inode_field " filespec field value"
+Modify the inode specified by
+.I filespec
+so that the inode field
+.I field
+has value
+.I value.
+The list of valid inode fields which can be set via this command
+can be displayed by using the command:
+.B set_inode_field -l
+Also available as
+.BR sif .
+.TP
+.BI set_mmp_value " field value"
+Modify the multiple-mount protection (MMP) data so that the MMP field
+.I field
+has value
+.I value.
+The list of valid MMP fields which can be set via this command
+can be displayed by using the command:
+.B set_mmp_value -l
+Also available as
+.BR smmp .
+.TP
+.BI set_super_value " field value"
+Set the superblock field
+.I field
+to
+.I value.
+The list of valid superblock fields which can be set via this command
+can be displayed by using the command:
+.B set_super_value -l
+Also available as
+.BR ssv .
+.TP
+.BI show_super_stats " [-h]"
+List the contents of the super block and the block group descriptors. If the
+.I -h
+flag is given, only print out the superblock contents. Also available as
+.BR stats .
+.TP
+.BI stat " filespec"
+Display the contents of the inode structure of the inode
+.IR filespec .
+.TP
+.BI testb " block [count]"
+Test if the block number
+.I block
+is marked as allocated in the block bitmap.
+If the optional argument
+.I count
+is present, then
+.I count
+blocks starting at block number
+.I block
+will be tested.
+.TP
+.BI testi " filespec"
+Test if the inode
+.I filespec
+is marked as allocated in the inode bitmap.
+.TP
+.BI undel " <inode_number> [pathname]"
+Undelete the specified inode number (which must be surrounded by angle
+brackets) so that it and its blocks are marked in use, and optionally
+link the recovered inode to the specified pathname. The
+.B e2fsck
+command should always be run after using the
+.B undel
+command to recover deleted files.
+.IP
+Note that if you are recovering a large number of deleted files, linking
+the inode to a directory may require the directory to be expanded, which
+could allocate a block that had been used by one of the
+yet-to-be-undeleted files. So it is safer to undelete all of the
+inodes without specifying a destination pathname, and then in a separate
+pass, use the debugfs
+.B link
+command to link the inode to the destination pathname, or use
+.B e2fsck
+to check the filesystem and link all of the recovered inodes to the
+lost+found directory.
+.TP
+.BI unlink " pathname"
+Remove the link specified by
+.I pathname
+to an inode. Note this does not adjust the inode reference counts.
+.TP
+.BI write " source_file out_file"
+Copy the contents of
+.I source_file
+into a newly-created file in the filesystem named
+.IR out_file .
+.TP
+.BI zap_block " [-f filespec] [-o offset] [-l length] [-p pattern] block_num"
+.TP
+Overwrite the block specified by
+.I block_num
+with zero (NUL) bytes, or if
+.I -p
+is given use the byte specified by
+.IR pattern .
+If
+.I -f
+is given then
+.I block_num
+is relative to the start of the file given by
+.IR filespec .
+The
+.I -o
+and
+.I -l
+options limit the range of bytes to zap to the specified
+.I offset
+and
+.I length
+relative to the start of the block.
+.TP
+.BI zap_block " [-f filespec] [-b bit] block_num"
+Bit-flip portions of the physical
+.IR block_num .
+If
+.I -f
+is given, then
+.I block_num
+is a logical block relative to the start of
+.IR filespec .
+.SH ENVIRONMENT VARIABLES
+.TP
+.B DEBUGFS_PAGER, PAGER
+The
+.B debugfs
+program always pipes the output of the some commands through a
+pager program. These commands include:
+.IR show_super_stats " (" stats ),
+.IR list_directory " (" ls ),
+.IR show_inode_info " (" stat ),
+.IR list_deleted_inodes " (" lsdel ),
+and
+.IR htree_dump .
+The specific pager can explicitly specified by the
+.B DEBUGFS_PAGER
+environment variable, and if it is not set, by the
+.B PAGER
+environment variable.
+.IP
+Note that since a pager is always used, the
+.BR less (1)
+pager is not particularly appropriate, since it clears the screen before
+displaying the output of the command and clears the output the screen
+when the pager is exited. Many users prefer to use the
+.BR less (1)
+pager for most purposes, which is why the
+.B DEBUGFS_PAGER
+environment variable is available to override the more general
+.B PAGER
+environment variable.

+libblkid - a library to handle device identification and token extraction
+
+Basic usage is as follows - there are two normal usage patterns:
+
+For cases where a program wants information about multiple devices, or
+expects to be doing multiple token searches, the program should
+directly initialize cache file via (second parameter is cache
+filename, NULL = default):
+
+ blkid_cache cache = NULL;
+ if (blkid_get_cache(&cache, NULL) < 0)
+ /* error reading the cache file, not really fatal */
+
+Note that if no cache file exists, an empty cache struct is still
+allocated. Usage of libblkid functions will use the cache to avoid
+needless device scans.
+
+The model of the blkid cache is that each device has a number of
+attributes that can be associated with it. Currently the attributes
+which are supported (and set) by blkid are:
+
+ TYPE filesystem type
+ UUID filesystem uuid
+ LABEL filesystem label
+
+
+How to use libblkid? Normally, you either want to find a device with
+a specific NAME=value token, or you want to output token(s) from a
+device. To find a device that matches a following attribute, you
+simply call the blkid_get_devname() function:
+
+ if ((devname = blkid_get_devname(cache, attribute_name, value))) {
+ /* do something with devname */
+ string_free(devname);
+ }
+
+The cache parameter is optional; if it is NULL, then the blkid library
+will load the default blkid.tab cache file, and then release the cache
+before function call returns. The return value is an allocated string
+which holds the resulting device name (if it is found). If the value
+is NULL, then attribute_name is parsed as if it were
+"<attribute_name>=<value>"; if it cannot be so parsed, then the
+original attribute_name is returned in a copied allocated string.
+This is a convenience to allow user programs to want to translate user
+input, whether it is of the form: "/dev/hda1", "LABEL=root",
+"UUID=082D-26E3", and get back a device name that it can use.
+
+Alternatively, of course, the programmer can pass an attribute name of
+"LABEL", and value of "root", if that is more convenient.
+
+Another common usage is to retrieve the value of a specific attribute
+for a particular device. This can be used to determine the filesystem
+type, or label, or uuid for a particular device:
+
+ if ((value = blkid_get_tag_value(cache, attribute_name, devname))) {
+ /* do something with value */
+ string_free(value);
+ }
+
+If a program needs to call multiple blkid functions, then passing in a
+cache value of NULL is not recommended, since the /etc/blkid.tab file
+will be repeatedly parsed over and over again, with memory allocated
+and deallocated. To initialize the blkid cache, blkid_get_cache()
+function is used:
+
+ if (blkid_get_cache(&cache, NULL) < 0)
+ goto errout;
+
+The second parameter of blkid_get_cache (if non-zero) is the alternate
+filename of the blkid cache file (where the default is
+/etc/blkid.tab). Normally, programs should just pass in NULL.
+
+If you have called blkid_get_cache(), you should call blkid_put_cache()
+when you are done using the blkid library functions. This will save the
+cache to the blkid.tab file, if you have write access to the file. It
+will also free all associated devices and tags:
+
+ blkid_put_cache(cache);

+@section Filesystem-level functions
+
+The following functions operate on a filesystem handle. Most EXT2FS
+Library functions require a filesystem handle as their first argument.
+There are two functions which create a filesystem handle,
+@code{ext2fs_open} and @code{ext2fs_initialize}.
+
+The filesystem can also be closed using @code{ext2fs_close}, and any
+changes to the superblock and group descripts can be written out to disk
+using @code{ext2fs_flush}.

+@subsection Opening an ext2 filesystem
+
+Most libext2fs functions take a filesystem handle of type
+@code{ext2_filsys}. A filesystem handle is created either by opening
+an existing function using @code{ext2fs_open}, or by initializing a new
+filesystem using @code{ext2fs_initialize}.
+
+@deftypefun errcode_t ext2fs_open (const char *@var{name}, int @var{flags}, int @var{superblock}, int @var{block_size}, io_manager @var{manager}, ext2_filsys *@var{ret_fs})
+
+Opens a filesystem named @var{name}, using the the io_manager
+@var{manager} to define the input/output routines needed to read and
+write the filesystem. In the case of the @code{unix_io} io_manager,
+@var{name} is interpreted as the Unix filename of the filesystem image.
+This is often a device file, such as @file{/dev/hda1}.
+
+The @var{superblock} parameter specifies the block number of the
+superblock which should be used when opening the filesystem.
+If @var{superblock} is zero, @code{ext2fs_open} will use the primary
+superblock located at offset 1024 bytes from the start of the filesystem
+image.
+
+The @var{block_size} parameter specifies the block size used by the
+filesystem. Normally this is determined automatically from the
+filesystem uperblock. If @var{block_size} is non-zero, it must match
+the block size found in the superblock, or the error
+@code{EXT2_ET_UNEXPECTED_BLOCK_SIZE} will be returned. The
+@var{block_size} parameter is also used to help fund the superblock when
+@var{superblock} is non-zero.
+
+The @var{flags} argument contains a bitmask of flags which control how
+the filesystem open should be handled.
+
+@table @code
+@item EXT2_FLAG_RW
+Open the filesystem for reading and writing. Without this flag, the
+filesystem is opened for reading only.
+
+@item EXT2_FLAG_FORCE
+Open the filesystem regardless of the feature sets listed in the
+superblock.

+@subsection Closing and flushing out changes
+
+@deftypefun errcode_t ext2fs_flush (ext2_filsys @var{fs})
+
+Write any changes to the high-level filesystem data structures in the
+@var{fs} filesystem. The following data structures will be written out:
+
+@itemize @bullet
+@item The filesystem superblock
+@item The filesystem group descriptors
+@item The filesystem bitmaps, if read in via @code{ext2fs_read_bitmaps}.
+@end itemize
+
+@end deftypefun
+
+@deftypefun void ext2fs_free (ext2_filsys @var{fs})
+
+Close the io_manager abstraction for @var{fs} and release all memory
+associated with the filesystem handle.
+@end deftypefun
+
+@deftypefun errcode_t ext2fs_close (ext2_filsys @var{fs})
+
+Flush out any changes to the high-level filesystem data structures using
+@code{ext2fs_flush} if the filesystem is marked dirty; then close and
+free the filesystem using @code{ext2fs_free}.

+@subsection Initializing a filesystem
+
+An ext2 filesystem is initializing by the @code{mke2fs} program. The
+two functions described here, @code{ext2fs_initialize} and
+@code{ext2fs_allocate_tables} do much of the initial work for setting up
+a filesystem. However, they don't do the whole job. @code{mke2fs}
+calls @code{ext2fs_initialize} to set up the filesystem superblock, and
+calls @code{ext2fs_allocate_tables} to allocate space for the inode
+table, and the inode and block bitmaps. In addition, @code{mke2fs} must
+also initialize the inode tables by clearing them with zeros, create the
+root and lost+found directories, and reserve the reserved inodes.
+
+@deftypefun errcode_t ext2fs_initialize (const char *@var{name}, int @var{flags}, struct ext2_super_block *@var{param}, io_manager @var{manager}, ext2_filsys *@var{ret_fs})
+
+This function is used by the @code{mke2fs} program to initialize a
+filesystem. The @code{ext2fs_initialize} function creates a filesystem
+handle which is returned in @var{ret_fs} that has been properly setup
+for a filesystem to be located in @var{name}, using the io_manager
+@var{manager}. The prototype superblock in @var{param} is used to
+supply parameters such as the number of blocks in the filesystem, the
+block size, etc.
+
+The @code{ext2fs_initialize} function does not actually do any I/O; that
+will be done when the application program calls @code{ext2fs_close} or
+@code{ext2fs_flush}. Also, this function only initializes the
+superblock and group descriptor structures. It does not create the
+inode table or the root directory. This must be done by the calling
+application, such as @code{mke2fs}.
+
+The following values may be set in the @var{param} prototype superblock;
+if a value of 0 is found in a field, @code{ext2fs_initialize} will use a
+default value. The calling application should zero out the prototype
+entire superblock, and then fill in any appropriate values.
+
+@table @code
+
+@item s_blocks_count
+The number of blocks in the filesystem. This parameter is mandatory and
+must be set by the calling application.
+
+@item s_inodes_count
+The number of inodes in the filesystem. The
+default value is determined by calculating the size of the filesystem,
+and creating one inode for every 4096 bytes.

+The first data block for the filesystem. For filesystem with a

+blocksizes, the superblock is still located at an offset of 1024 bytes,

+and returns a file handle in @var{ret}. If an inode structure is

+
+Iterate over all of the blocks in inode number @var{ino} in filesystem
+@var{fs}, by calling the function @var{func} for each block in the
+inode. The @var{block_buf} parameter should either be NULL, or if the
+@code{ext2fs_block_iterate} function is called repeatedly, the overhead
+of allocating and freeing scratch memory can be avoided by passing a
+pointer to a scratch buffer which must be at least as big as three times the
+filesystem's blocksize.
+
+The @var{flags} parameter controls how the iterator will function:
+
+@table @samp
+
+@item BLOCK_FLAG_HOLE
+This flag indiciates that the interator function should be called on
+blocks where the block number is zero (also known as ``holes''.) It is
+also known as BLOCK_FLAG_APPEND, since it is also used by functions
+such as ext2fs_expand_dir() to add a new block to an inode.
+
+@item BLOCK_FLAG_DEPTH_TRAVERSE
+This flag indicates that the iterator function for the
+indirect, doubly indirect, etc. blocks should be called after all
+of the blocks containined in the indirect blocks are processed.
+This is useful if you are going to be deallocating blocks from an
+inode.
+
+@item BLOCK_FLAG_DATA_ONLY
+This flag indicates that the iterator function should be
+called for data blocks only.
+
+@end table
+
+The callback function @var{func} is called with a number of parameters;
+the @var{fs} and @var{private} parameters are self-explanatory, and
+their values are taken from the parameters to
+@code{ext2fs_block_iterate}. (The @var{private} data structure is
+generally used by callers to @code{ext2fs_block_iterate} so that some
+private data structure can be passed to the callback function. The
+@var{blockcnt} parameter, if non-negative, indicates the logical block
+number of a data block in the inode. If @var{blockcnt} is less than

+will be one of the following values: BLOCK_COUNT_IND, BLOCK_COUNT_DIND,
+BLOCK_COUNT_TIND, or BLOCK_COUNT_TRANSLATOR. The @var{blocknr} is a
+pointer to the inode or indirect block entry listing physical block
+number. The callback function may modify the physical block number, if

+This function is much like @code{ext2fs_block_iterate}, except that the

+The dblist abstraction stores a list of blocks belonging to

+@subsection Inode count functions
+
+The icount abstraction is a specialized data type used by @code{e2fsck}
+to store how many times a particular inode is referenced by the
+filesystem. This is used twice; once to store the actual number of times
+that the inode is reference; and once to store the claimed number of times
+the inode is referenced according to the inode structure.
+
+This abstraction is designed to be extremely efficient for storing this
+sort of information, by taking advantage of the following properties of
+inode counts, namely (1) inode counts are very often zero (because
+the inode is currrently not in use), and (2) many files have a inode
+count of 1 (because they are a file which has no additional hard links).
+
+@deftypefun errcode_t ext2fs_create_icount2 (ext2_filsys @var{fs}, int @var{flags}, int @var{size}, ext2_icount_t @var{hint}, ext2_icount_t *@var{ret})
+
+Creates an icount stucture for a filesystem @var{fs}, with initial space
+for @var{size} inodes whose count is greater than 1. The @var{flags}
+parameter is either 0 or @code{EXT2_ICOUNT_OPT_INCREMENT}, which
+indicates that icount structure should be able to increment inode counts
+quickly. The icount structure is returned in @var{ret}. The returned
+icount structure initially has a count of zero for all inodes.
+
+The @var{hint} parameter allows the caller to optionally pass in another
+icount structure which is used to initialize the array of inodes whose
+count is greater than 1. It is used purely as a speed optimization so
+that the icount structure can determine in advance which inodes are
+likely to contain a count grater than 1.

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item first col stuff @tab second col stuff @tab third col
+% @item
+% first col stuff
+% @tab
+% second col stuff
+% @tab
+% third col
+% @item first col stuff @tab second col stuff
+% @tab Many paragraphs of text may be used in any column.
+%
+% They will wrap at the width determined by the template.
+% @item@tab@tab This will be in third column.
+% @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+% to baseline.

+[tytso:19940101.1200EST]
+
+Add new options -l and -L, to append to and modify the bad-blocks list.
+
+Fix bugs in bad-block cloning.
+
+[tytso:19931230.1832EST]
+
+Clean up e2fsck and library to be clean even when compiling with full
+warnings enabled.
+
+Make e2fsck deal with zero-length directories correctly.
+
+Deleted inodes from old ext2fs code (inodes with dtime set but
+non-zero link count) are detected, and the user is given the
+opportunity to clear them.
+
+The last bit in the last group of the block bitmap badding was not
+being checked; now fixed.
+
+The free_blocks and free_inodes count in the last group weren't being
+checked. Now fixed.
+
+[tytso:19931101.0007EST]
+
+Fixed bugs with root reallocation; previously the parent pointers in
+the dirinfo structure would get corrupted, causing many different '..'
+links to be wrong. Also, the inode link count for the root directory
+wasn't always being set correctly. (All of this would be fixed on
+the second e2fsck, however).
+
+Fixed to recognize filesystem corruption caused by mke2fs 0.2b (where
+/ and /lost+found had non-zero dtime entries). Offers to fix /'s
+dtime entry.
+
+e2fsck will now expand the /lost+found directory if it runs out of room.
+
+Fixed dependency on BLOCK_SIZE in pass2. e2fsck will now handle 4k
+filesystems w/o problems.
+
+e2fsck will now move bad blocks found in the inode bitmaps, block
+bitmaps, and in the inode tables. (Can't handle bad blocks found in
+the superblock and the group descriptors.) (Doesn't update alternate
+superblocks, group descriptors.)
+
+e2fsck now supports the -b option, to allow a user to specify an
+alternate superblock.
+
+The -B option now specifies the blocksize of the filesystem. (If not
+specified, and the -b option is specified, e2fsck will attempt to
+search through various blocksizes to find the correct one.)
+
+Added manual page.

+ * and the whole thing (message+CRC) is a multiple of the given
+ * CRC polynomial. To check the CRC, you can either check that the
+ * CRC matches the recomputed value, *or* you can check that the
+ * remainder computed on the message+CRC is 0. This latter approach
+ * is used by a lot of hardware implementations, and is why so many
+ * protocols put the end-of-frame flag after the CRC.
+ *
+ * It's actually the same long division you learned in school, except that
+ * - We're working in binary, so the digits are only 0 and 1, and
+ * - When dividing polynomials, there are no carries. Rather than add and
+ * subtract, we just xor. Thus, we tend to get a bit sloppy about
+ * the difference between adding and subtracting.
+ *
+ * A 32-bit CRC polynomial is actually 33 bits long. But since it's
+ * 33 bits long, bit 32 is always going to be set, so usually the CRC
+ * is written in hex with the most significant bit omitted. (If you're
+ * familiar with the IEEE 754 floating-point format, it's the same idea.)
+ *
+ * Note that a CRC is computed over a string of *bits*, so you have
+ * to decide on the endianness of the bits within each byte. To get
+ * the best error-detecting properties, this should correspond to the
+ * order they're actually sent. For example, standard RS-232 serial is
+ * little-endian; the most significant bit (sometimes used for parity)
+ * is sent last. And when appending a CRC word to a message, you should
+ * do it in the right order, matching the endianness.
+ *
+ * Just like with ordinary division, the remainder is always smaller than
+ * the divisor (the CRC polynomial) you're dividing by. Each step of the
+ * division, you take one more digit (bit) of the dividend and append it
+ * to the current remainder. Then you figure out the appropriate multiple
+ * of the divisor to subtract to being the remainder back into range.
+ * In binary, it's easy - it has to be either 0 or 1, and to make the
+ * XOR cancel, it's just a copy of bit 32 of the remainder.
+ *
+ * When computing a CRC, we don't care about the quotient, so we can
+ * throw the quotient bit away, but subtract the appropriate multiple of
+ * the polynomial from the remainder and we're back to where we started,
+ * ready to process the next bit.
+ *
+ * A big-endian CRC written this way would be coded like:
+ * for (i = 0; i < input_bits; i++) {
+ * multiple = remainder & 0x80000000 ? CRCPOLY : 0;
+ * remainder = (remainder << 1 | next_input_bit()) ^ multiple;
+ * }
+ * Notice how, to get at bit 32 of the shifted remainder, we look
+ * at bit 31 of the remainder *before* shifting it.
+ *
+ * But also notice how the next_input_bit() bits we're shifting into
+ * the remainder don't actually affect any decision-making until
+ * 32 bits later. Thus, the first 32 cycles of this are pretty boring.
+ * Also, to add the CRC to a message, we need a 32-bit-long hole for it at
+ * the end, so we have to add 32 extra cycles shifting in zeros at the
+ * end of every message,
+ *
+ * So the standard trick is to rearrage merging in the next_input_bit()
+ * until the moment it's needed. Then the first 32 cycles can be precomputed,
+ * and merging in the final 32 zero bits to make room for the CRC can be
+ * skipped entirely.
+ * This changes the code to:
+ * for (i = 0; i < input_bits; i++) {
+ * remainder ^= next_input_bit() << 31;
+ * multiple = (remainder & 0x80000000) ? CRCPOLY : 0;
+ * remainder = (remainder << 1) ^ multiple;
+ * }
+ * With this optimization, the little-endian code is simpler:
+ * for (i = 0; i < input_bits; i++) {
+ * remainder ^= next_input_bit();
+ * multiple = (remainder & 1) ? CRCPOLY : 0;
+ * remainder = (remainder >> 1) ^ multiple;
+ * }
+ *
+ * Note that the other details of endianness have been hidden in CRCPOLY
+ * (which must be bit-reversed) and next_input_bit().
+ *
+ * However, as long as next_input_bit is returning the bits in a sensible
+ * order, we can actually do the merging 8 or more bits at a time rather
+ * than one bit at a time:
+ * for (i = 0; i < input_bytes; i++) {
+ * remainder ^= next_input_byte() << 24;
+ * for (j = 0; j < 8; j++) {
+ * multiple = (remainder & 0x80000000) ? CRCPOLY : 0;
+ * remainder = (remainder << 1) ^ multiple;
+ * }
+ * }
+ * Or in little-endian:
+ * for (i = 0; i < input_bytes; i++) {
+ * remainder ^= next_input_byte();
+ * for (j = 0; j < 8; j++) {
+ * multiple = (remainder & 1) ? CRCPOLY : 0;
+ * remainder = (remainder << 1) ^ multiple;
+ * }
+ * }
+ * If the input is a multiple of 32 bits, you can even XOR in a 32-bit
+ * word at a time and increase the inner loop count to 32.
+ *
+ * You can also mix and match the two loop styles, for example doing the
+ * bulk of a message byte-at-a-time and adding bit-at-a-time processing
+ * for any fractional bytes at the end.
+ *
+ * The only remaining optimization is to the byte-at-a-time table method.
+ * Here, rather than just shifting one bit of the remainder to decide
+ * in the correct multiple to subtract, we can shift a byte at a time.
+ * This produces a 40-bit (rather than a 33-bit) intermediate remainder,
+ * but again the multiple of the polynomial to subtract depends only on
+ * the high bits, the high 8 bits in this case.
+ *
+ * The multiple we need in that case is the low 32 bits of a 40-bit
+ * value whose high 8 bits are given, and which is a multiple of the
+ * generator polynomial. This is simply the CRC-32 of the given
+ * one-byte message.
+ *
+ * Two more details: normally, appending zero bits to a message which
+ * is already a multiple of a polynomial produces a larger multiple of that
+ * polynomial. To enable a CRC to detect this condition, it's common to
+ * invert the CRC before appending it. This makes the remainder of the
+ * message+crc come out not as zero, but some fixed non-zero value.
+ *
+ * The same problem applies to zero bits prepended to the message, and
+ * a similar solution is used. Instead of starting with a remainder of
+ * 0, an initial remainder of all ones is used. As long as you start
+ * the same way on decoding, it doesn't make a difference.

+e2fsck \- check a Linux ext2/ext3/ext4 file system

+]
+.I device
+.SH DESCRIPTION
+.B e2fsck
+is used to check the ext2/ext3/ext4 family of file systems.
+For ext3 and ext4 filesystems that use a journal, if the system has been
+shut down uncleanly without any errors, normally, after replaying the
+committed transactions in the journal, the file system should be
+marked as clean. Hence, for filesystems that use journalling,
+.B e2fsck
+will normally replay the journal and exit, unless its superblock
+indicates that further checking is required.
+.PP
+.I device
+is the device file where the filesystem is stored (e.g.
+.IR /dev/hdc1 ).
+.PP
+Note that in general it is not safe to run
+.B e2fsck
+on mounted filesystems. The only exception is if the
+.B \-n
+option is specified, and
+.BR \-c ,
+.BR \-l ,
+or
+.B -L
+options are
+.I not
+specified. However, even if it is safe to do so, the results printed by
+.B e2fsck
+are not valid if the filesystem is mounted. If
+.B e2fsck
+asks whether or not you should check a filesystem which is mounted,
+the only correct answer is ``no''. Only experts who really know what
+they are doing should consider answering this question in any other way.
+.SH OPTIONS
+.TP
+.B \-a
+This option does the same thing as the
+.B \-p
+option. It is provided for backwards compatibility only; it is
+suggested that people use
+.B \-p
+option whenever possible.
+.TP
+.BI \-b " superblock"
+Instead of using the normal superblock, use an alternative superblock
+specified by
+.IR superblock .
+This option is normally used when the primary superblock has been
+corrupted. The location of the backup superblock is dependent on the
+filesystem's blocksize. For filesystems with 1k blocksizes, a backup
+superblock can be found at block 8193; for filesystems with 2k
+blocksizes, at block 16384; and for 4k blocksizes, at block 32768.
+.IP
+Additional backup superblocks can be determined by using the
+.B mke2fs
+program using the
+.B \-n
+option to print out where the superblocks were created. The
+.B \-b
+option to
+.BR mke2fs ,
+which specifies blocksize of the filesystem must be specified in order
+for the superblock locations that are printed out to be accurate.
+.IP
+If an alternative superblock is specified and
+the filesystem is not opened read-only, e2fsck will make sure that the
+primary superblock is updated appropriately upon completion of the
+filesystem check.
+.TP
+.BI \-B " blocksize"
+Normally,
+.B e2fsck
+will search for the superblock at various different
+block sizes in an attempt to find the appropriate block size.
+This search can be fooled in some cases. This option forces
+.B e2fsck
+to only try locating the superblock at a particular blocksize.
+If the superblock is not found,
+.B e2fsck
+will terminate with a fatal error.
+.TP
+.B \-c
+This option causes
+.B e2fsck
+to use
+.BR badblocks (8)
+program to do a read-only scan of the device in order to find any bad
+blocks. If any bad blocks are found, they are added to the bad block
+inode to prevent them from being allocated to a file or directory. If
+this option is specified twice, then the bad block scan will be done
+using a non-destructive read-write test.
+.TP
+.BI \-C " fd"
+This option causes
+.B e2fsck
+to write completion information to the specified file descriptor
+so that the progress of the filesystem
+check can be monitored. This option is typically used by programs
+which are running
+.BR e2fsck .
+If the file descriptor number is negative, then absolute value of
+the file descriptor will be used, and the progress information will be
+suppressed initially. It can later be enabled by sending the
+.B e2fsck
+process a SIGUSR1 signal.
+If the file descriptor specified is 0,
+.B e2fsck
+will print a completion bar as it goes about its business. This requires
+that e2fsck is running on a video console or terminal.
+.TP
+.B \-d
+Print debugging output (useless unless you are debugging
+.BR e2fsck ).
+.TP
+.B \-D
+Optimize directories in filesystem. This option causes e2fsck to
+try to optimize all directories, either by reindexing them if the
+filesystem supports directory indexing, or by sorting and compressing
+directories for smaller directories, or for filesystems using
+traditional linear directories.
+.IP
+Even without the
+.B \-D
+option,
+.B e2fsck
+may sometimes optimize a few directories --- for example, if
+directory indexing is enabled and a directory is not indexed and would
+benefit from being indexed, or if the index structures are corrupted
+and need to be rebuilt. The
+.B \-D
+option forces all directories in the filesystem to be optimized. This can
+sometimes make them a little smaller and slightly faster to search, but
+in practice, you should rarely need to use this option.
+.IP
+The
+.B \-D
+option will detect directory entries with duplicate names in a single
+directory, which e2fsck normally does not enforce for performance reasons.
+.TP
+.BI \-E " extended_options"
+Set e2fsck extended options. Extended options are comma
+separated, and may take an argument using the equals ('=') sign. The
+following options are supported:
+.RS 1.2i
+.TP
+.BI ea_ver= extended_attribute_version
+Set the version of the extended attribute blocks which
+.B e2fsck
+will require while checking the filesystem. The version number may
+be 1 or 2. The default extended attribute version format is 2.
+.TP
+.BI journal_only
+Only replay the journal if required, but do not perform any further checks
+or repairs.
+.TP
+.BI fragcheck
+During pass 1, print a detailed report of any discontiguous blocks for
+files in the filesystem.
+.TP
+.BI discard
+Attempt to discard free blocks and unused inode blocks after the full
+filesystem check (discarding blocks is useful on solid state devices and sparse
+/ thin-provisioned storage). Note that discard is done in pass 5 AFTER the
+filesystem has been fully checked and only if it does not contain recognizable
+errors. However there might be cases where
+.B e2fsck
+does not fully recognize a problem and hence in this case this
+option may prevent you from further manual data recovery.
+.TP
+.BI nodiscard
+Do not attempt to discard free blocks and unused inode blocks. This option is
+exactly the opposite of discard option. This is set as default.
+.RE
+.TP
+.B \-f
+Force checking even if the file system seems clean.
+.TP
+.B \-F
+Flush the filesystem device's buffer caches before beginning. Only
+really useful for doing
+.B e2fsck
+time trials.
+@JDEV@.TP
+@JDEV@.BI \-j " external-journal"
+@JDEV@Set the pathname where the external-journal for this filesystem can be
+@JDEV@found.
+.TP
+.BI \-k
+When combined with the
+.B \-c
+option, any existing bad blocks in the bad blocks list are preserved,
+and any new bad blocks found by running
+.BR badblocks (8)
+will be added to the existing bad blocks list.
+.TP
+.BI \-l " filename"
+Add the block numbers listed in the file specified by
+.I filename
+to the list of bad blocks. The format of this file is the same as the
+one generated by the
+.BR badblocks (8)
+program. Note that the block numbers are based on the blocksize
+of the filesystem. Hence,
+.BR badblocks (8)
+must be given the blocksize of the filesystem in order to obtain correct
+results. As a result, it is much simpler and safer to use the
+.B -c
+option to
+.BR e2fsck ,
+since it will assure that the correct parameters are passed to the
+.B badblocks
+program.
+.TP
+.BI \-L " filename"
+Set the bad blocks list to be the list of blocks specified by
+.IR filename .
+(This option is the same as the
+.B \-l
+option, except the bad blocks list is cleared before the blocks listed
+in the file are added to the bad blocks list.)
+.TP
+.B \-n
+Open the filesystem read-only, and assume an answer of `no' to all
+questions. Allows
+.B e2fsck
+to be used non-interactively. This option
+may not be specified at the same time as the
+.B \-p
+or
+.B \-y
+options.
+.TP
+.B \-p
+Automatically repair ("preen") the file system. This option will cause
+.B e2fsck
+to automatically
+fix any filesystem problems that can be safely fixed without human
+intervention. If
+.B e2fsck
+discovers a problem which may require the system administrator
+to take additional corrective action,
+.B e2fsck
+will print a description of the problem and then exit with the value 4
+logically or'ed into the exit code. (See the \fBEXIT CODE\fR section.)
+This option is normally used by the system's boot scripts. It may not
+be specified at the same time as the
+.B \-n
+or
+.B \-y
+options.
+.TP
+.B \-r
+This option does nothing at all; it is provided only for backwards
+compatibility.
+.TP
+.B \-t
+Print timing statistics for
+.BR e2fsck .
+If this option is used twice, additional timing statistics are printed
+on a pass by pass basis.
+.TP
+.B \-v
+Verbose mode.
+.TP
+.B \-V
+Print version information and exit.
+.TP
+.B \-y
+Assume an answer of `yes' to all questions; allows
+.B e2fsck
+to be used non-interactively. This option
+may not be specified at the same time as the
+.B \-n
+or
+.B \-p
+options.
+.SH EXIT CODE
+The exit code returned by
+.B e2fsck
+is the sum of the following conditions:
+.br
+\ 0\ \-\ No errors
+.br
+\ 1\ \-\ File system errors corrected
+.br
+\ 2\ \-\ File system errors corrected, system should
+.br
+\ \ \ \ be rebooted
+.br
+\ 4\ \-\ File system errors left uncorrected
+.br
+\ 8\ \-\ Operational error
+.br
+\ 16\ \-\ Usage or syntax error
+.br
+\ 32\ \-\ E2fsck canceled by user request
+.br
+\ 128\ \-\ Shared library error
+.br
+.SH SIGNALS
+The following signals have the following effect when sent to
+.BR e2fsck .
+.TP
+.B SIGUSR1
+This signal causes
+.B e2fsck
+to start displaying a completion bar or emitting progress information.
+(See discussion of the
+.B \-C
+option.)
+.TP
+.B SIGUSR2
+This signal causes
+.B e2fsck
+to stop displaying a completion bar or emitting progress information.
+.SH REPORTING BUGS
+Almost any piece of software will have bugs. If you manage to find a
+filesystem which causes
+.B e2fsck
+to crash, or which
+.B e2fsck
+is unable to repair, please report it to the author.
+.PP
+Please include as much information as possible in your bug report.
+Ideally, include a complete transcript of the
+.B e2fsck
+run, so I can see exactly what error messages are displayed. (Make sure
+the messages printed by
+.B e2fsck
+are in English; if your system has been
+configured so that
+.BR e2fsck 's
+messages have been translated into another language, please set the the
+.B LC_ALL
+environment variable to
+.B C
+so that the transcript of e2fsck's output will be useful to me.)
+If you
+have a writable filesystem where the transcript can be stored, the
+.BR script (1)
+program is a handy way to save the output of
+.B e2fsck
+to a file.
+.PP
+It is also useful to send the output of
+.BR dumpe2fs (8).
+If a specific inode or inodes seems to be giving
+.B e2fsck
+trouble, try running the
+.BR debugfs (8)
+command and send the output of the
+.BR stat (1u)
+command run on the relevant inode(s). If the inode is a directory, the
+.B debugfs
+.I dump
+command will allow you to extract the contents of the directory inode,
+which can sent to me after being first run through
+.BR uuencode (1).
+The most useful data you can send to help reproduce
+the bug is a compressed raw image dump of the filesystem, generated using
+.BR e2image (8).
+See the
+.BR e2image (8)
+man page for more details.
+.PP
+Always include the full version string which
+.B e2fsck
+displays when it is run, so I know which version you are running.

+.SH NAME
+e2fsck.conf \- Configuration file for e2fsck
+.SH DESCRIPTION
+.I e2fsck.conf
+is the configuration file for
+.BR e2fsck (8).
+It controls the default behavior of
+.BR e2fsck (8)
+while it is checking ext2, ext3, or ext4 filesystems.
+.PP
+The
+.I e2fsck.conf
+file uses an INI-style format. Stanzas, or top-level sections, are
+delimited by square braces: [ ]. Within each section, each line
+defines a relation, which assigns tags to values, or to a subsection,
+which contains further relations or subsections.
+.\" Tags can be assigned multiple values
+An example of the INI-style format used by this configuration file
+follows below:
+.P
+ [section1]
+.br
+ tag1 = value_a
+.br
+ tag1 = value_b
+.br
+ tag2 = value_c
+.P
+ [section 2]
+.br
+ tag3 = {
+.br
+ subtag1 = subtag_value_a
+.br
+ subtag1 = subtag_value_b
+.br
+ subtag2 = subtag_value_c
+.br
+ }
+.br
+ tag1 = value_d
+.br
+ tag2 = value_e
+.br
+ }
+.P
+Comments are delimited by a semicolon (';') or a hash ('#') character
+at the beginning of the comment, and are terminated by the end of
+line character.
+.P
+Tags and values must be quoted using double quotes if they contain
+spaces. Within a quoted string, the standard backslash interpretations
+apply: "\en" (for the newline character),
+"\et" (for the tab character), "\eb" (for the backspace character),
+and "\e\e" (for the backslash character).
+.P
+The following stanzas are used in the
+.I e2fsck.conf
+file. They will be described in more detail in future sections of this
+document.
+.TP
+.I [options]
+This stanza contains general configuration parameters for
+.BR e2fsck 's
+behavior.
+.TP
+.I [problems]
+This stanza allows the administrator to reconfigure how e2fsck handles
+various filesystem inconsistencies.
+.TP
+.I [scratch_files]
+This stanza controls when e2fsck will attempt to use scratch files to
+reduce the need for memory.
+.SH THE [options] STANZA
+The following relations are defined in the
+.I [options]
+stanza.
+.TP
+.I allow_cancellation
+If this relation is set to a boolean value of true, then if the user
+interrupts e2fsck using ^C, and the filesystem is not explicitly flagged
+as containing errors, e2fsck will exit with an exit status of 0 instead
+of 32. This setting defaults to false.
+.TP
+.I accept_time_fudge
+Unfortunately, due to Windows' unfortunate design decision
+to configure the hardware clock to tick localtime, instead
+of the more proper and less error-prone UTC time, many
+users end up in the situation where the system clock is
+incorrectly set at the time when e2fsck is run.
+.IP
+Historically this was usually due to some distributions
+having buggy init scripts and/or installers that didn't
+correctly detect this case and take appropriate
+countermeasures. Unfortunately, this is occasionally
+true even today, usually due to a
+buggy or misconfigured virtualization manager or the
+installer not having access to a network time server
+during the installation process. So by default, we allow
+the superblock times to be fudged by up to 24 hours.
+This can be disabled by setting
+.I accept_time_fudge
+to the
+boolean value of false. This setting defaults to true.
+.TP
+.I broken_system_clock
+The
+.BR e2fsck (8)
+program has some heuristics that assume that the system clock is
+correct. In addition, many system programs make similar assumptions.
+For example, the UUID library depends on time not going backwards in
+order for it to be able to make its guarantees about issuing universally
+unique ID's. Systems with broken system clocks, are well, broken.
+However, broken system clocks, particularly in embedded systems, do
+exist. E2fsck will attempt to use heuristics to determine if the time
+can not be trusted; and to skip time-based checks if this is true. If
+this boolean is set to true, then e2fsck will always assume that the
+system clock can not be trusted.
+.TP
+.I buggy_init_scripts
+This boolean relation is an alias for
+.I accept_time_fudge
+for backwards compatibility; it used to
+be that the behavior defined by
+.I accept_time_fudge
+above defaulted to false, and
+.I buggy_init_scripts
+would enable superblock time field to be wrong by up to 24 hours. When
+we changed the default, we also renamed this boolean relation to
+.IR accept_time_fudge.
+.TP
+.I clear_test_fs_flag
+This boolean relation controls whether or not
+.BR e2fsck (8)
+will offer to clear
+the test_fs flag if the ext4 filesystem is available on the system. It
+defaults to true.
+.TP
+.I defer_check_on_battery
+This boolean relation controls whether or not the interval between
+filesystem checks (either based on time or number of mounts) should
+be doubled if the system is running on battery. This setting defaults to
+true.
+.TP
+.I indexed_dir_slack_percentage
+When
+.BR e2fsck (8)
+repacks a indexed directory, reserve the specified percentage of
+empty space in each leaf nodes so that a few new entries can
+be added to the directory without splitting leaf nodes, so that
+the average fill ratio of directories can be maintained at a
+higher, more efficient level. This relation defaults to 20
+percent.
+.TP
+.I log_dir
+If the
+.I log_filename
+relation contains a relative pathname, then the log file will be placed
+in the directory named by the
+.I log_dir
+relation.
+.TP
+.I log_dir_fallback
+This relation contains an alternate directory that will be used if the
+directory specified by
+.I log_dir
+is not available or is not writeable.
+.TP
+.I log_dir_wait
+If this boolean relation is true, them if the directories specified by
+.I log_dir
+or
+.I log_dir_fallback
+are not available or are not yet writeable, e2fsck will save the output
+in a memory buffer, and a child process will periodically test to see if
+the log directory has become available after the boot sequence has
+mounted the requiste filesytem for reading/writing. This implements the
+functionality provided by
+.BR logsave (8)
+for e2fsck log files.
+.TP
+.I log_filename
+This relation specifies the file name where a copy of e2fsck's output
+will be written. If certain problem reports are suppressed using the
+.I max_count_problems
+relation, (or on a per-problem basis using the
+.I max_count
+relation), the full set of problem reports will be written to the log
+file. The filename may contain various percent-expressions (%D, %T, %N,
+etc.) which will be expanded so that the file name for the log file can
+include things like date, time, device name, and other run-time
+parameters. See the
+.B LOGGING
+section for more details.
+.TP
+.I max_count_problems
+This relation specifies the maximum number of problem reports of a
+particular type will be printed to stdout before further problem reports
+of that type are squelched. This can be useful if the console is slow
+(i.e., connected to a serial port) and so a large amount of output could
+end up delaying the boot process for a long time (potentially hours).
+.TP
+.I report_features
+If this boolean relation is true, e2fsck will print the file system
+features as part of its verbose reporting (i.e., if the
+.B -v
+option is specified)
+.TP
+.I report_time
+If this boolean relation is true, e2fsck will run as if the options
+.B -tt
+are always specified. This will cause e2fsck to print timing statistics
+on a pass by pass basis for full file system checks.
+.TP
+.I report_verbose
+If this boolean relation is true, e2fsck will run as if the option
+.B -v
+is always specified. This will cause e2fsck to print some additional
+information at the end of each full file system check.
+.SH THE [problems] STANZA
+Each tag in the
+.I [problems]
+stanza names a problem code specified with a leading "0x" followed by
+six hex digits.
+The value of the tag is a subsection where the relations in that
+subsection override the default treatment of that particular problem
+code.
+.P
+Note that inappropriate settings in this stanza may cause
+.B e2fsck
+to behave incorrectly, or even crash. Most system administrators should
+not be making changes to this section without referring to source code.
+.P
+Within each problem code's subsection, the following tags may be used:
+.TP
+.I description
+This relation allows the message which is printed when this filesystem
+inconsistency is detected to be overridden.
+.TP
+.I preen_ok
+This boolean relation overrides the default behavior controlling
+whether this filesystem problem should be automatically fixed when
+.B e2fsck
+is running in preen mode.
+.TP
+.I max_count
+This integer relation overrides the
+.I max_count_problems
+parameter (set in the options section) for this particular problem.
+.TP
+.I no_ok
+This boolean relation overrides the default behavior determining
+whether or not the filesystem will be marked as inconsistent if the user
+declines to fix the reported problem.
+.TP
+.I no_default
+This boolean relation overrides whether the default answer for this
+problem (or question) should be "no".
+.TP
+.I preen_nomessage
+This boolean relation overrides the default behavior controlling
+whether or not the description for this filesystem problem should
+be suppressed when
+.B e2fsck
+is running in preen mode.
+.TP
+.I no_nomsg
+This boolean relation overrides the default behavior controlling
+whether or not the description for this filesystem problem should
+be suppressed when a problem forced not to be fixed, either because
+.B e2fsck
+is run with the
+.B -n
+option or because the
+.I force_no
+flag has been set for the problem.
+.TP
+.I force_no
+This boolean option, if set to true, forces a problem to never be fixed.
+That is, it will be as if the user problem responds 'no' to the question
+of 'should this problem be fixed?'. The
+.I force_no
+option even overrides the
+.B -y
+option given on the command-line (just for the specific problem, of course).
+.SH THE [scratch_files] STANZA
+The following relations are defined in the
+.I [scratch_files]
+stanza.
+.TP
+.I directory
+If the directory named by this relation exists and is writeable, then
+e2fsck will attempt to use this directory to store scratch files instead
+of using in-memory data structures.
+.TP
+.I numdirs_threshold
+If this relation is set, then in-memory data structures be used if the
+number of directories in the filesystem are fewer than amount specified.
+.TP
+.I dirinfo
+This relation controls whether or not the scratch file directory is used
+instead of an in-memory data structure for directory information. It
+defaults to true.
+.TP
+.I icount
+This relation controls whether or not the scratch file directory is used
+instead of an in-memory data structure when tracking inode counts. It
+defaults to true.
+.SH LOGGING
+E2fsck has the facility to save the information from an e2fsck run in a
+directory so that a system administrator can review its output at their
+leisure. This allows information captured during the automatic e2fsck
+preen run, as well as a manually started e2fsck run, to be saved for
+posterity. This facility is controlled by the
+.IR log_filename ,
+.IR log_dir ,
+.IR log_dir_fallback ,
+and
+.I log_dir_wait
+relations in the
+.I [options]
+stanza.
+.PP
+The filename in
+.I log_filename
+may contain the following percent-expressions that will be expanded as
+follows.
+.TP
+.B %d
+The current day of the month
+.TP
+.B %D
+The current date; this is a equivalent of
+.B %Y%m%d
+.TP
+.B %h
+The hostname of the system.

+.SH EXAMPLES
+The following recipe will prevent e2fsck from aborting during the boot
+process when a filesystem contains orphaned files. (Of course, this is
+not always a good idea, since critical files that are needed for the
+security of the system could potentially end up in lost+found, and
+starting the system without first having a system administrator check
+things out may be dangerous.)

+.br
+ }
+.P
+The following recipe will cause an e2fsck logfile to be written to the
+directory /var/log/e2fsck, with a filename that contains the device
+name, the hostname of the system, the date, and time: e.g.,
+"e2fsck-sda3.server.INFO.20120314-112142". If the directory containing
+/var/log is located on the root file system
+which is initially mounted read-only, then the output will be saved in
+memory and written out once the root file system has been remounted
+read/write. To avoid too much detail from being written to the serial
+console (which could potentially slow down the boot sequence), only print
+no more than 16 instances of each type of file system corruption.

+ * Pass 1 of e2fsck iterates over all the inodes in the filesystems,
+ * and applies the following tests to each inode:
+ *
+ * - The mode field of the inode must be legal.
+ * - The size and block count fields of the inode are correct.
+ * - A data block must not be used by another inode
+ *
+ * Pass 1 also gathers the collects the following information:
+ *
+ * - A bitmap of which inodes are in use. (inode_used_map)
+ * - A bitmap of which inodes are directories. (inode_dir_map)
+ * - A bitmap of which inodes are regular files. (inode_reg_map)
+ * - A bitmap of which inodes have bad fields. (inode_bad_map)
+ * - A bitmap of which inodes are in bad blocks. (inode_bb_map)
+ * - A bitmap of which inodes are imagic inodes. (inode_imagic_map)
+ * - A bitmap of which blocks are in use. (block_found_map)
+ * - A bitmap of which blocks are in use by two inodes (block_dup_map)
+ * - The data blocks of the directory inodes. (dir_map)
+ *
+ * Pass 1 is designed to stash away enough information so that the
+ * other passes should not need to read in the inode information
+ * during the normal course of a filesystem check. (Althogh if an
+ * inconsistency is detected, other passes may need to read in an
+ * inode to fix it.)
+ *
+ * Note that pass 1B will be invoked if there are any duplicate blocks

+ * pass1b.c --- Pass #1b of e2fsck
+ *
+ * This file contains pass1B, pass1C, and pass1D of e2fsck. They are
+ * only invoked if pass 1 discovered blocks which are in use by more
+ * than one inode.
+ *
+ * Pass1B scans the data blocks of all the inodes again, generating a
+ * complete list of duplicate blocks and which inodes have claimed
+ * them.
+ *
+ * Pass1C does a tree-traversal of the filesystem, to determine the
+ * parent directories of these inodes. This step is necessary so that
+ * e2fsck can print out the pathnames of affected inodes.
+ *
+ * Pass1D is a reconciliation pass. For each inode with duplicate
+ * blocks, the user is prompted if s/he would like to clone the file
+ * (so that the file gets a fresh copy of the duplicated blocks) or
+ * simply to delete the file.

+ * left in the directory block.
+ * - The length of the name in the directory entry (name_len)
+ * should be less than (rec_len - 8).
+ * - The inode number in the directory entry should be within
+ * legal bounds.
+ * - The inode number should refer to a in-use inode.
+ * - The first entry should be '.', and its inode should be
+ * the inode of the directory.
+ * - The second entry should be '..'.
+ *
+ * To minimize disk seek time, the directory blocks are processed in
+ * sorted order of block numbers.
+ *
+ * Pass 2 also collects the following information:

+ * Pass #3 assures that all directories are connected to the
+ * filesystem tree, using the following algorithm:
+ *
+ * First, the root directory is checked to make sure it exists; if
+ * not, e2fsck will offer to create a new one. It is then marked as
+ * "done".
+ *
+ * Then, pass3 interates over all directory inodes; for each directory
+ * it attempts to trace up the filesystem tree, using dirinfo.parent
+ * until it reaches a directory which has been marked "done". If it
+ * can not do so, then the directory must be disconnected, and e2fsck
+ * will offer to reconnect it to /lost+found. While it is chasing
+ * parent pointers up the filesystem tree, if pass3 sees a directory
+ * twice, then it has detected a filesystem loop, and it will again
+ * offer to reconnect the directory to /lost+found in to break the
+ * filesystem loop.
+ *
+ * Pass 3 also contains the subroutine, e2fsck_reconnect_file() to
+ * reconnect inodes to /lost+found; this subroutine is also used by
+ * pass 4. e2fsck_reconnect_file() calls get_lost_and_found(), which
+ * is responsible for creating /lost+found if it does not exist.
+ *
+ * Pass 3 frees the following data structures:
+ * - The dirinfo directory information cache.
