+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 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 Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ 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 Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+ When we speak of free software, we are referring to freedom of use,
+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 and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+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 other code 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.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes a de-facto standard. To achieve this, non-free programs must
+be allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ 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, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser 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 combine 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) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) 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.
+
+ d) 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.
+
+ e) 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 materials to be 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 with
+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 Lesser 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.

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 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 Lesser GPL. It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+ 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 Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it. You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+ When we speak of free software, we are referring to freedom of use,
+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 and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+ To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+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 other code 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.
+
+ We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ To protect each distributor, we want to make it very clear that
+there is no warranty for the free library. Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+ Finally, software patents pose a constant threat to the existence of
+any free program. We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder. Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+ Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License. This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License. We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+ When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library. The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom. The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+ We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License. It also provides other free software developers Less
+of an advantage over competing non-free programs. These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries. However, the Lesser license provides advantages in certain
+special circumstances.
+
+ For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard. To achieve this, non-free programs must be
+allowed to use the library. A more frequent case is that a free
+library does the same job as widely used non-free libraries. In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+ In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software. For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+ Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+ 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, whereas the latter must
+be combined with the library in order to run.
+
+ GNU LESSER GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser 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 combine 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) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (1) uses at run time a
+ copy of the library already present on the user's computer system,
+ rather than copying library functions into the executable, and (2)
+ will operate properly with a modified version of the library, if
+ the user installs one, as long as the modified version is
+ interface-compatible with the version that the work was made with.
+
+ c) 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.
+
+ d) 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.
+
+ e) 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 materials to be 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 with
+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 Lesser 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.
+
+ <one line to give the library's name and a brief idea of what it does.>

+
+ This library 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
+ Lesser General Public License for more details.
+

+ License along with this library; 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.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:
+

+ * Netlink Attributes Construction/Parsing Interface
+ *
+ * \section attr_sec Netlink Attributes
+ * Netlink attributes allow for data chunks of arbitary length to be
+ * attached to a netlink message. Each attribute is encoded with a
+ * type and length field, both 16 bits, stored in the attribute header
+ * preceding the attribute data. The main advantage of using attributes
+ * over packing everything into the family header is that the interface
+ * stays extendable as new attributes can supersede old attributes while
+ * remaining backwards compatible. Also attributes can be defined optional
+ * thus avoiding the transmission of unnecessary empty data blocks.
+ * Special nested attributes allow for more complex data structures to
+ * be transmitted, e.g. trees, lists, etc.
+ *
+ * While not required, netlink attributes typically follow the family
+ * header of a netlink message and must be properly aligned to NLA_ALIGNTO:
+ * @code
+ * +----------------+- - -+---------------+- - -+------------+- - -+
+ * | Netlink Header | Pad | Family Header | Pad | Attributes | Pad |
+ * +----------------+- - -+---------------+- - -+------------+- - -+
+ * @endcode
+ *
+ * The actual attributes are chained together each separately aligned to
+ * NLA_ALIGNTO. The position of an attribute is defined based on the
+ * length field of the preceding attributes:
+ * @code
+ * +-------------+- - -+-------------+- - -+------
+ * | Attribute 1 | Pad | Attribute 2 | Pad | ...
+ * +-------------+- - -+-------------+- - -+------
+ * nla_next(attr1)------^
+ * @endcode
+ *
+ * The attribute itself consists of the attribute header followed by
+ * the actual payload also aligned to NLA_ALIGNTO. The function nla_data()
+ * returns a pointer to the start of the payload while nla_len() returns
+ * the length of the payload in bytes.
+ *
+ * \b Note: Be aware, NLA_ALIGNTO equals to 4 bytes, therefore it is not
+ * safe to dereference any 64 bit data types directly.
+ *
+ * @code
+ * <----------- nla_total_size(payload) ----------->
+ * <-------- nla_attr_size(payload) --------->

+ *
+ * @subsection attr_datatypes Attribute Data Types
+ * A number of basic data types are supported to simplify access and
+ * validation of netlink attributes. This data type information is
+ * not encoded in the attribute, both the kernel and userspace part
+ * are required to share this information on their own.
+ *
+ * One of the major advantages of these basic types is the automatic
+ * validation of each attribute based on an attribute policy. The
+ * validation covers most of the checks required to safely use
+ * attributes and thus keeps the individual sanity check to a minimum.
+ *
+ * Never access attribute payload without ensuring basic validation
+ * first, attributes may:
+ * - not be present even though required
+ * - contain less actual payload than expected
+ * - fake a attribute length which exceeds the end of the message
+ * - contain unterminated character strings
+ *
+ * Policies are defined as array of the struct nla_policy. The array is
+ * indexed with the attribute type, therefore the array must be sized
+ * accordingly.
+ * @code
+ * static struct nla_policy my_policy[ATTR_MAX+1] = {
+ * [ATTR_FOO] = { .type = ..., .minlen = ..., .maxlen = ... },
+ * };
+ *
+ * err = nla_validate(attrs, attrlen, ATTR_MAX, &my_policy);
+ * @endcode
+ *
+ * Some basic validations are performed on every attribute, regardless of type.
+ * - If the attribute type exceeds the maximum attribute type specified or
+ * the attribute type is lesser-or-equal than zero, the attribute will
+ * be silently ignored.
+ * - If the payload length falls below the \a minlen value the attribute
+ * will be rejected.
+ * - If \a maxlen is non-zero and the payload length exceeds the \a maxlen
+ * value the attribute will be rejected.
+ *
+ *
+ * @par Unspecific Attribute (NLA_UNSPEC)
+ * This is the standard type if no type is specified. It is used for
+ * binary data of arbitary length. Typically this attribute carries
+ * a binary structure or a stream of bytes.
+ * @par
+ * @code
+ * // In this example, we will assume a binary structure requires to
+ * // be transmitted. The definition of the structure will typically
+ * // go into a header file available to both the kernel and userspace
+ * // side.
+ * //
+ * // Note: Be careful when putting 64 bit data types into a structure.
+ * // The attribute payload is only aligned to 4 bytes, dereferencing
+ * // the member may fail.
+ * struct my_struct {
+ * int a;
+ * int b;
+ * };
+ *
+ * // The validation function will not enforce an exact length match to
+ * // allow structures to grow as required. Note: While it is allowed
+ * // to add members to the end of the structure, changing the order or
+ * // inserting members in the middle of the structure will break your
+ * // binary interface.
+ * static struct nla_policy my_policy[ATTR_MAX+1] = {
+ * [ATTR_MY_STRICT] = { .type = NLA_UNSPEC,
+ * .minlen = sizeof(struct my_struct) },
+ *
+ * // The binary structure is appened to the message using nla_put()
+ * struct my_struct foo = { .a = 1, .b = 2 };
+ * nla_put(msg, ATTR_MY_STRUCT, sizeof(foo), &foo);
+ *
+ * // On the receiving side, a pointer to the structure pointing inside
+ * // the message payload is returned by nla_get().
+ * if (attrs[ATTR_MY_STRUCT])
+ * struct my_struct *foo = nla_get(attrs[ATTR_MY_STRUCT]);
+ * @endcode
+ *
+ * @par Integers (NLA_U8, NLA_U16, NLA_U32, NLA_U64)
+ * Integers come in different sizes from 8 bit to 64 bit. However, since the
+ * payload length is aligned to 4 bytes, integers smaller than 32 bit are
+ * only useful to enforce the maximum range of values.
+ * @par
+ * \b Note: There is no difference made between signed and unsigned integers.
+ * The validation only enforces the minimal payload length required to store
+ * an integer of specified type.
+ * @par
+ * @code
+ * // Even though possible, it does not make sense to specify .minlen or
+ * // .maxlen for integer types. The data types implies the corresponding
+ * // minimal payload length.
+ * static struct nla_policy my_policy[ATTR_MAX+1] = {
+ * [ATTR_FOO] = { .type = NLA_U32 },
+ *
+ * // Numeric values can be appended directly using the respective
+ * // nla_put_uxxx() function
+ * nla_put_u32(msg, ATTR_FOO, 123);
+ *
+ * // Same for the receiving side.
+ * if (attrs[ATTR_FOO])
+ * uint32_t foo = nla_get_u32(attrs[ATTR_FOO]);
+ * @endcode
+ *
+ * @par Character string (NLA_STRING)
+ * This data type represents a NUL terminated character string of variable
+ * length. For binary data streams the type NLA_UNSPEC is recommended.
+ * @par
+ * @code
+ * // Enforce a NUL terminated character string of at most 4 characters
+ * // including the NUL termination.
+ * static struct nla_policy my_policy[ATTR_MAX+1] = {
+ * [ATTR_BAR] = { .type = NLA_STRING, maxlen = 4 },
+ *
+ * // nla_put_string() creates a string attribute of the necessary length
+ * // and appends it to the message including the NUL termination.
+ * nla_put_string(msg, ATTR_BAR, "some text");
+ *
+ * // It is safe to use the returned character string directly if the
+ * // attribute has been validated as the validation enforces the proper
+ * // termination of the string.
+ * if (attrs[ATTR_BAR])
+ * char *text = nla_get_string(attrs[ATTR_BAR]);
+ * @endcode
+ *
+ * @par Flag (NLA_FLAG)
+ * This attribute type may be used to indicate the presence of a flag. The
+ * attribute is only valid if the payload length is zero. The presence of
+ * the attribute header indicates the presence of the flag.
+ * @par
+ * @code
+ * // This attribute type is special as .minlen and .maxlen have no effect.
+ * static struct nla_policy my_policy[ATTR_MAX+1] = {
+ * [ATTR_FLAG] = { .type = NLA_FLAG },
+ *
+ * // nla_put_flag() appends a zero sized attribute to the message.
+ * nla_put_flag(msg, ATTR_FLAG);
+ *
+ * // There is no need for a receival function, the presence is the value.
+ * if (attrs[ATTR_FLAG])
+ * // flag is present
+ * @endcode
+ *
+ * @par Micro Seconds (NLA_MSECS)
+ *
+ * @par Nested Attribute (NLA_NESTED)
+ * Attributes can be nested and put into a container to create groups, lists
+ * or to construct trees of attributes. Nested attributes are often used to
+ * pass attributes to a subsystem where the top layer has no knowledge of the
+ * configuration possibilities of each subsystem.
+ * @par
+ * \b Note: When validating the attributes using nlmsg_validate() or
+ * nlmsg_parse() it will only affect the top level attributes. Each
+ * level of nested attributes must be validated seperately using
+ * nla_parse_nested() or nla_validate().
+ * @par
+ * @code
+ * // The minimal length policy may be used to enforce the presence of at
+ * // least one attribute.
+ * static struct nla_policy my_policy[ATTR_MAX+1] = {
+ * [ATTR_OPTS] = { .type = NLA_NESTED, minlen = NLA_HDRLEN },
+ *
+ * // Nested attributes are constructed by enclosing the attributes
+ * // to be nested with calls to nla_nest_start() respetively nla_nest_end().
+ * struct nlattr *opts = nla_nest_start(msg, ATTR_OPTS);
+ * nla_put_u32(msg, ATTR_FOO, 123);
+ * nla_put_string(msg, ATTR_BAR, "some text");
+ * nla_nest_end(msg, opts);
+ *
+ * // Various methods exist to parse nested attributes, the easiest being
+ * // nla_parse_nested() which also allows validation in the same step.
+ * if (attrs[ATTR_OPTS]) {
+ * struct nlattr *nested[ATTR_MAX+1];
+ *
+ * nla_parse_nested(nested, ATTR_MAX, attrs[ATTR_OPTS], &policy);
+ *
+ * if (nested[ATTR_FOO])
+ * uint32_t foo = nla_get_u32(nested[ATTR_FOO]);
+ * }
+ * @endcode
+ *
+ * @subsection attr_exceptions Exception Based Attribute Construction
+ * Often a large number of attributes are added to a message in a single
+ * function. In order to simplify error handling, a second set of
+ * construction functions exist which jump to a error label when they
+ * fail instead of returning an error code. This second set consists
+ * of macros which are named after their error code based counterpart
+ * except that the name is written all uppercase.
+ *
+ * All of the macros jump to the target \c nla_put_failure if they fail.
+ * @code
+ * void my_func(struct nl_msg *msg)
+ * {
+ * NLA_PUT_U32(msg, ATTR_FOO, 10);
+ * NLA_PUT_STRING(msg, ATTR_BAR, "bar");
+ *

+ * @defgroup cache_mngr Manager
+ * @brief Helps keeping caches up to date.
+ *
+ * The purpose of a cache manager is to keep track of caches and
+ * automatically receive event notifications to keep the caches
+ * up to date with the kernel state. Each manager has exactly one
+ * netlink socket assigned which limits the scope of each manager
+ * to exactly one netlink family. Therefore all caches committed
+ * to a manager must be part of the same netlink family. Due to the
+ * nature of a manager, it is not possible to have a cache maintain
+ * two instances of the same cache type. The socket is subscribed
+ * to the event notification group of each cache and also put into
+ * non-blocking mode. Functions exist to poll() on the socket to
+ * wait for new events to be received.
+ *

+ * libnl is a set of libraries to deal with the netlink protocol and some
+ * of the high level protocols implemented on top of it. Its goal is to
+ * simplify netlink protocol usage and to create an abstraction layer using
+ * object based interfaces for various netlink based subsystems.The library
+ * was developed and tested on the 2.6.x kernel releases but it may work with
+ * older kernel series.

+ *
+ * @section remarks Remarks
+ *
+ * @subsection cache_alloc Allocation of Caches
+ *
+ * Almost all subsystem provide a function to allocate a new cache
+ * of some form. The function usually looks like this:
+ * @code
+ * struct nl_cache *<object name>_alloc_cache(struct nl_sock *sk);
+ * @endcode
+ *
+ * These functions allocate a new cache for the own object type,
+ * initializes it properly and updates it to represent the current
+ * state of their master, e.g. a link cache would include all
+ * links currently configured in the kernel.
+ *
+ * Some of the allocation functions may take additional arguments
+ * to further specify what will be part of the cache.
+ *
+ * All such functions return a newly allocated cache or NULL
+ * in case of an error.
+ *
+ * @subsection addr Setting of Addresses
+ * @code
+ * int <object name>_set_addr(struct nl_object *, struct nl_addr *)
+ * @endcode
+ *
+ * All attribute functions avaiable for assigning addresses to objects
+ * take a struct nl_addr argument. The provided address object is
+ * validated against the address family of the object if known already.
+ * The assignment fails if the address families mismatch. In case the
+ * address family has not been specified yet, the address family of
+ * the new address is elected to be the new requirement.
+ *
+ * The function will acquire a new reference on the address object
+ * before assignment, the caller is NOT responsible for this.
+ *
+ * All functions return 0 on success or a negative error code.
+ *
+ * @subsection flags Flags to Character StringTranslations
+ * All functions converting a set of flags to a character string follow
+ * the same principles, therefore, the following information applies
+ * to all functions convertings flags to a character string and vice versa.
+ *
+ * @subsubsection flags2str Flags to Character String
+ * @code
+ * char *<object name>_flags2str(int flags, char *buf, size_t len)
+ * @endcode
+ * @arg flags Flags.
+ * @arg buf Destination buffer.
+ * @arg len Buffer length.
+ *
+ * Converts the specified flags to a character string separated by
+ * commas and stores it in the specified destination buffer.
+ *
+ * @return The destination buffer
+ *
+ * @subsubsection str2flags Character String to Flags
+ * @code
+ * int <object name>_str2flags(const char *name)
+ * @endcode
+ * @arg name Name of flag.
+ *
+ * Converts the provided character string specifying a flag
+ * to the corresponding numeric value.
+ *
+ * @return Link flag or a negative value if none was found.
+ *
+ * @subsubsection type2str Type to Character String
+ * @code
+ * char *<object name>_<type>2str(int type, char *buf, size_t len)
+ * @endcode
+ * @arg type Type as numeric value
+ * @arg buf Destination buffer.
+ * @arg len Buffer length.
+ *
+ * Converts an identifier (type) to a character string and stores
+ * it in the specified destination buffer.
+ *
+ * @return The destination buffer or the type encoded in hexidecimal
+ * form if the identifier is unknown.
+ *
+ * @subsubsection str2type Character String to Type
+ * @code
+ * int <object name>_str2<type>(const char *name)
+ * @endcode
+ * @arg name Name of identifier (type).
+ *
+ * Converts the provided character string specifying a identifier
+ * to the corresponding numeric value.
+ *
+ * @return Identifier as numeric value or a negative value if none was found.

+ * @page core_doc Core Library (-lnl)
+ *
+ * @section core_intro Introduction
+ *
+ * The core library contains the fundamentals required to communicate over
+ * netlink sockets. It deals with connecting and unconnecting of sockets,
+ * sending and receiving of data, provides a customizeable receiving state
+ * machine, and provides a abstract data type framework which eases the
+ * implementation of object based netlink protocols where objects are added,
+ * removed, or modified with the help of netlink messages.
+ *
+ * @section core_toc Table of Contents
+ *
+ * - \ref proto_fund
+ * - \ref sk_doc
+ * - \ref rxtx_doc
+ * - \ref cb_doc
+ *
+ * @section proto_fund Netlink Protocol Fundamentals
+ *
+ * The netlink protocol is a socket based IPC mechanism used for communication
+ * between userspace processes and the kernel. The netlink protocol uses the
+ * \c AF_NETLINK address family and defines a protocol type for each subsystem
+ * protocol (e.g. NETLINK_ROUTE, NETLINK_NETFILTER, etc). Its addressing
+ * schema is based on a 32 bit port number, formerly referred to as PID, which
+ * uniquely identifies each peer.
+ *
+ * The netlink protocol is based on messages each limited to the size of a
+ * memory page and consists of the netlink message header (struct nlmsghdr)
+ * plus the payload attached to it. The payload can consist of arbitary data
+ * but often contains a fixed sized family specifc header followed by a
+ * stream of \ref attr_doc. The use of attributes dramatically increases
+ * the flexibility of the protocol and allows for the protocol to be
+ * extended while maintaining backwards compatibility.
+ *
+ * The netlink message header (struct nlmsghdr):
+ * @code
+ * 0 1 2 3
+ * 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1
+ * +-------------------------------------------------------------+
+ * | Length |
+ * +------------------------------+------------------------------+
+ * | Type | Flags |
+ * +------------------------------+------------------------------+
+ * | Sequence Number |
+ * +-------------------------------------------------------------+
+ * | Port (Address) |
+ * +-------------------------------------------------------------+
+ * @endcode
+ *
+ * Netlink differs between requests, notifications, and replies. Requests
+ * are messages which have the \c NLM_F_REQUEST flag set and are meant to
+ * request an action from the receiver. A request is typically sent from
+ * a userspace process to the kernel. Every request should be assigned a
+ * sequence number which should be incremented for each request sent on the
+ * sending side. Depending on the nature of the request, the receiver may
+ * reply to the request with regular netlink messages which should contain
+ * the same sequence number as the request it relates to. Notifications are
+ * of informal nature and don't expect a reply, therefore the sequence number
+ * is typically set to 0. It should be noted that unlike in protocols such as
+ * TCP there is no strict enforcment of the sequence number. The sole purpose
+ * of sequence numbers is to assist a sender in relating replies to the
+ * corresponding requests.
+ *
+ * @msc
+ * A,B;
+ * A=>B [label="GET (seq=1, NLM_F_REQUEST)"];
+ * A<=B [label="PUT (seq=1)"];
+ * ...;
+ * A<=B [label="NOTIFY (seq=0)"];
+ * @endmsc
+ *
+ * If the size of a reply exceeds the size of a memory page and thus exceeds
+ * the maximum message size, the reply can be split into a series of multipart
+ * messages. A multipart message has the \c flag NLM_F_MULTI set and the
+ * receiver is expected to continue parsing the reply until the special
+ * message type \c NLMSG_DONE is received.
+ *
+ * @msc
+ * A,B;
+ * A=>B [label="GET (seq=1, NLM_F_REQUEST)"];
+ * A<=B [label="PUT (seq=1, NLM_F_MULTI)"];
+ * ...;
+ * A<=B [label="PUT (seq=1, NLM_F_MULTI)"];
+ * A<=B [label="NLMSG_DONE (seq=1)"];
+ * @endmsc
+ *
+ * Errors can be reported using the standard message type \c NLMSG_ERROR which
+ * can carry an error code and the netlink mesage header of the request.
+ * Error messages should set their sequence number to the sequence number
+ * of the message which caused the error.
+ *
+ * @msc
+ * A,B;
+ * A=>B [label="GET (seq=1, NLM_F_REQUEST)"];
+ * A<=B [label="NLMSG_ERROR code=EINVAL (seq=1)"];
+ * @endmsc
+ *
+ * The \c NLMSG_ERROR message type is also used to send acknowledge messages.
+ * An acknowledge message can be requested by setting the \c NLM_F_ACK flag
+ * message except that the error code is set to 0.
+ *

+ * @section sk_doc Dealing with Netlink Sockets
+ *
+ * In order to use the netlink protocol, a netlink socket is required. Each
+ * socket defines a completely independent context for sending and receiving
+ * of messages. The netlink socket and all its related attributes are
+ * represented by struct nl_sock.
+ *
+ * @code
+ * nl_socket_alloc() Allocate new socket structure.
+ * nl_socket_free(s) Free socket structure.
+ * @endcode
+ *
+ * @subsection local_port Local Port
+ * The local port number uniquely identifies the socket and is used to
+ * address it. A unique local port is generated automatically when the socket
+ * is allocated. It will consist of the Process ID (22 bits) and a random
+ * number (10 bits) to allow up to 1024 sockets per process.
+ *
+ * @code
+ * nl_socket_get_local_port(sk) Return the peer's port number.
+ * nl_socket_set_local_port(sk, port) Set the peer's port number.
+ * @endcode
+ *
+ * @subsection peer_port Peer Port
+ * A peer port can be assigned to the socket which will result in all unicast
+ * messages sent over the socket to be addresses to the corresponding peer. If
+ * no peer is specified, the kernel will try to automatically bind the socket
+ * to a kernel side socket of the same netlink protocol family. It is common
+ * practice not to bind the socket to a peer port as typically only one kernel
+ * side socket exists per netlink protocol family.
+ *
+ * @code
+ * nl_socket_get_peer_port(sk) Return the local port number.
+ * nl_socket_set_peer_port(sk, port) Set the local port number.
+ * @endcode
+ *
+ * @subsection sock_fd File Descriptor
+ * The file descriptor of the socket(2).
+ *
+ * @code
+ * nl_socket_get_fd(sk) Return file descriptor.
+ * nl_socket_set_buffer_size(sk, rx, tx) Set buffer size of socket.
+ * nl_socket_set_nonblocking(sk) Set socket to non-blocking state.
+ * @endcode
+ *
+ * @subsection group_sub Group Subscriptions
+ * Each socket can subscribe to multicast groups of the netlink protocol
+ * family it is bound to. The socket will then receive a copy of each
+ * message sent to any of the groups. Multicast groups are commonly used
+ * to implement event notifications. Prior to kernel 2.6.14 the group
+ * subscription was performed using a bitmask which limited the number of
+ * groups per protocol family to 32. This outdated interface can still be
+ * accessed via the function nl_join_groups even though it is not recommended
+ * for new code. Starting with 2.6.14 a new method was introduced which
+ * supports subscribing to an almost unlimited number of multicast groups.
+ *
+ * @code
+ * nl_socket_add_membership(sk, group) Become a member of a multicast group.
+ * nl_socket_drop_membership(sk, group) Drop multicast group membership.
+ * nl_join_groups(sk, groupmask) Join a multicast group (obsolete).
+ * @endcode
+ *
+ * @subsection seq_num Sequence Numbers
+ * The socket keeps track of the sequence numbers used. The library will
+ * automatically verify the sequence number of messages received unless
+ * the check was disabled using the function nl_socket_disable_seq_check().
+ * When a message is sent using nl_send_auto_complete(), the sequence number
+ * is automatically filled in, and replies will be verified correctly.
+ *
+ * @code
+ * nl_socket_disable_seq_check(sk) Disable checking of sequece numbers.
+ * nl_socket_use_seq(sk) Use sequence number and bump to next.
+ * @endcode
+ *
+ * @subsection sock_cb Callback Configuration
+ * Every socket is associated a callback configuration which enables the
+ * applications to hook into various internal functions and control the
+ * receiving and sendings semantics. For more information, see section
+ * \ref cb_doc.
+ *
+ * @code
+ * nl_socket_alloc_cb(cb) Allocate socket based on callback set.
+ * nl_socket_get_cb(sk) Return callback configuration.
+ * nl_socket_set_cb(sk, cb) Replace callback configuration.
+ * nl_socket_modify_cb(sk, ...) Modify a specific callback function.
+ * @endcode
+ *
+ * @subsection sk_other Other Functions
+ * @code
+ * nl_socket_enable_auto_ack(sock) Enable automatic request of ACK.
+ * nl_socket_disable_auto_ack(sock) Disable automatic request of ACK.
+ * nl_socket_enable_msg_peek(sock) Enable message peeking.
+ * nl_socket_disable_msg_peek(sock) Disable message peeking.
+ * nl_socket_set_passcred(sk, state) Enable/disable credential passing.
+ * nl_socket_recv_pktinfo(sk, state) Enable/disable packet information.

+ * Callbacks and overwriting capabilities are provided to control various
+ * semantics of the library. All callback functions are packed together in
+ * struct nl_cb which is attached to a netlink socket or passed on to
+ * the respective functions directly.
+ *
+ * @subsection cb_ret_doc Callback Return Values
+ * Callback functions can control the flow of the calling layer by returning
+ * appropriate error codes:
+ * @code
+ * Action ID | Description
+ * -----------------+-------------------------------------------------------
+ * NL_OK | Proceed with whatever comes next.
+ * NL_SKIP | Skip message currently being processed and continue
+ * | with next message.
+ * NL_STOP | Stop parsing and discard all remaining messages in
+ * | this set of messages.
+ * @endcode
+ *
+ * All callbacks are optional and a default action is performed if no
+ * application specific implementation is provided:
+ *
+ * @code
+ * Callback ID | Default Return Value
+ * ------------------+----------------------
+ * NL_CB_VALID | NL_OK
+ * NL_CB_FINISH | NL_STOP
+ * NL_CB_OVERRUN | NL_STOP
+ * NL_CB_SKIPPED | NL_SKIP
+ * NL_CB_ACK | NL_STOP
+ * NL_CB_MSG_IN | NL_OK
+ * NL_CB_MSG_OUT | NL_OK
+ * NL_CB_INVALID | NL_STOP
+ * NL_CB_SEQ_CHECK | NL_OK
+ * NL_CB_SEND_ACK | NL_OK
+ * |
+ * Error Callback | NL_STOP
+ * @endcode
+ *
+ * In order to simplify typical usages of the library, different sets of
+ * default callback implementations exist:
+ * @code
+ * NL_CB_DEFAULT: No additional actions
+ * NL_CB_VERBOSE: Automatically print warning and error messages to a file
+ * descriptor as appropriate. This is useful for CLI based
+ * applications.
+ * NL_CB_DEBUG: Print informal debugging information for each message
+ * received. This will result in every message beint sent or
+ * received to be printed to the screen in a decoded,
+ * human-readable format.
+ * @endcode
+ *
+ * @par 1) Setting up a callback set
+ * @code
+ * // Allocate a callback set and initialize it to the verbose default set
+ * struct nl_cb *cb = nl_cb_alloc(NL_CB_VERBOSE);
+ *
+ * // Modify the set to call my_func() for all valid messages
+ * nl_cb_set(cb, NL_CB_VALID, NL_CB_CUSTOM, my_func, NULL);
+ *
+ * // Set the error message handler to the verbose default implementation
+ * // and direct it to print all errors to the given file descriptor.
+ * FILE *file = fopen(...);

+ * Netlink Message Construction/Parsing Interface
+ *
+ * The following information is partly extracted from RFC3549
+ * (ftp://ftp.rfc-editor.org/in-notes/rfc3549.txt)
+ *
+ * @par Message Format
+ * Netlink messages consist of a byte stream with one or multiple
+ * Netlink headers and an associated payload. If the payload is too big
+ * to fit into a single message it, can be split over multiple Netlink
+ * messages, collectively called a multipart message. For multipart
+ * messages, the first and all following headers have the \c NLM_F_MULTI
+ * Netlink header flag set, except for the last header which has the
+ * Netlink header type \c NLMSG_DONE.
+ *
+ * @par
+ * The Netlink message header (\link nlmsghdr struct nlmsghdr\endlink) is shown below.
+ * @code
+ * 0 1 2 3
+ * 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

+ * +----------------------------+- - -+- - - - - - - - - - -+- - -+

+ * @par The ACK Netlink Message
+ * This message is actually used to denote both an ACK and a NACK.
+ * Typically, the direction is from FEC to CPC (in response to an ACK
+ * request message). However, the CPC should be able to send ACKs back
+ * to FEC when requested.

+ * @par Example
+ * @code
+ * // Various methods exist to create/allocate a new netlink
+ * // message.
+ * //
+ * // nlmsg_alloc() will allocate an empty netlink message with
+ * // a maximum payload size which defaults to the page size of
+ * // the system. This default size can be modified using the
+ * // function nlmsg_set_default_size().
+ * struct nl_msg *msg = nlmsg_alloc();
+ *
+ * // Very often, the message type and message flags are known
+ * // at allocation time while the other fields are auto generated:
+ * struct nl_msg *msg = nlmsg_alloc_simple(MY_TYPE, MY_FLAGS);
+ *
+ * // Alternatively an existing netlink message header can be used
+ * // to inherit the header values:
+ * struct nlmsghdr hdr = {
+ * .nlmsg_type = MY_TYPE,
+ * .nlmsg_flags = MY_FLAGS,
+ * };
+ * struct nl_msg *msg = nlmsg_inherit(&hdr);
+ *
+ * // Last but not least, netlink messages received from netlink sockets
+ * // can be converted into nl_msg objects using nlmsg_convert(). This
+ * // will create a message with a maximum payload size which equals the
+ * // length of the existing netlink message, therefore no more data can
+ * // be appened without calling nlmsg_expand() first.
+ * struct nl_msg *msg = nlmsg_convert(nlh_from_nl_sock);
+ *
+ * // Payload may be added to the message via nlmsg_append(). The fourth
+ * // parameter specifies the number of alignment bytes the data should
+ * // be padding with at the end. Common values are 0 to disable it or
+ * // NLMSG_ALIGNTO to ensure proper netlink message padding.
+ * nlmsg_append(msg, &mydata, sizeof(mydata), 0);
+ *
+ * // Sometimes it may be necessary to reserve room for data but defer
+ * // the actual copying to a later point, nlmsg_reserve() can be used
+ * // for this purpose:
+ * void *data = nlmsg_reserve(msg, sizeof(mydata), NLMSG_ALIGNTO);
+ *
+ * // Attributes may be added using the attributes interface.
+ *
+ * // After successful use of the message, the memory must be freed
+ * // using nlmsg_free()
+ * nlmsg_free(msg);

+ * @endcode
+ *
+ * @par Notes on IFF_PROMISC and IFF_ALLMULTI flags
+ * Although you can query the status of IFF_PROMISC and IFF_ALLMULTI
+ * they do not represent the actual state in the kernel but rather
+ * whether the flag has been enabled/disabled by userspace. The link
+ * may be in promiscious mode even if IFF_PROMISC is not set in a link
+ * dump request response because promiscity might be needed by the driver
+ * for a period of time.
+ *
+ * @note The unit of the transmission queue length depends on the
+ * link type, a common unit is \a packets.
+ *
+ * @par 1) Retrieving information about available links
+ * @code
+ * // The first step is to retrieve a list of all available interfaces within
+ * // the kernel and put them into a cache.
+ * struct nl_cache *cache = rtnl_link_alloc_cache(sk);
+ *
+ * // In a second step, a specific link may be looked up by either interface
+ * // index or interface name.
+ * struct rtnl_link *link = rtnl_link_get_by_name(cache, "lo");
+ *
+ * // rtnl_link_get_by_name() is the short version for translating the
+ * // interface name to an interface index first like this:
+ * int ifindex = rtnl_link_name2i(cache, "lo");
+ * struct rtnl_link *link = rtnl_link_get(cache, ifindex);
+ *
+ * // After successful usage, the object must be given back to the cache
+ * rtnl_link_put(link);
+ * @endcode
+ *
+ * @par 2) Changing link attributes
+ * @code
+ * // In order to change any attributes of an existing link, we must allocate
+ * // a new link to hold the change requests:
+ * struct rtnl_link *request = rtnl_link_alloc();
+ *
+ * // Now we can go on and specify the attributes we want to change:
+ * rtnl_link_set_weight(request, 300);
+ * rtnl_link_set_mtu(request, 1360);
+ *
+ * // We can also shut an interface down administratively
+ * rtnl_link_unset_flags(request, rtnl_link_str2flags("up"));
+ *
+ * // Actually, we should know which link to change, so let's look it up
+ * struct rtnl_link *old = rtnl_link_get(cache, "eth0");
+ *
+ * // Two ways exist to commit this change request, the first one is to
+ * // build the required netlink message and send it out in one single
+ * // step:
+ * rtnl_link_change(sk, old, request);
+ *
+ * // An alternative way is to build the netlink message and send it
+ * // out yourself using nl_send_auto_complete()
+ * struct nl_msg *msg = rtnl_link_build_change_request(old, request);
+ * nl_send_auto_complete(sk, nlmsg_hdr(msg));
+ * nlmsg_free(msg);
+ *
+ * // Don't forget to give back the link object ;->
+ * rtnl_link_put(old);
+ * @endcode
+ *
+ * @par 3) Link Type Specific Attributes
+ * @code
+ * // Some link types offer additional parameters and statistics specific
+ * // to their type. F.e. a VLAN link can be configured like this:
+ * //
+ * // Allocate a new link and set the info type to "vlan". This is required
+ * // to prepare the link to hold vlan specific attributes.
+ * struct rtnl_link *request = rtnl_link_alloc();
+ * rtnl_link_set_info_type(request, "vlan");
+ *
+ * // Now vlan specific attributes can be set:
+ * rtnl_link_vlan_set_id(request, 10);
+ * rtnl_link_vlan_set_ingress_map(request, 2, 8);
+ *
+ * // Of course the attributes can also be read, check the info type
+ * // to make sure you are using the right access functions:
+ * char *type = rtnl_link_get_info_type(link);
+ * if (!strcmp(type, "vlan"))
+ * int id = rtnl_link_vlan_get_id(link);
+ * @endcode

+ * @ingroup rtnl
+ * @defgroup neigh Neighbours
+ * @brief
+ *
+ * The neighbour table establishes bindings between protocol addresses and
+ * link layer addresses for hosts sharing the same physical link. This
+ * module allows you to access and manipulate the content of these tables.
+ *
+ * @par Neighbour States
+ * @code
+ * NUD_INCOMPLETE
+ * NUD_REACHABLE
+ * NUD_STALE
+ * NUD_DELAY
+ * NUD_PROBE
+ * NUD_FAILED
+ * NUD_NOARP
+ * NUD_PERMANENT
+ * @endcode
+ *
+ * @par Neighbour Flags
+ * @code
+ * NTF_PROXY
+ * NTF_ROUTER
+ * @endcode
+ *
+ * @par Neighbour Identification
+ * A neighbour is uniquely identified by the attributes listed below, whenever
+ * you refer to an existing neighbour all of the attributes must be set.
+ * Neighbours from caches automatically have all required attributes set.
+ * - interface index (rtnl_neigh_set_ifindex())
+ * - destination address (rtnl_neigh_set_dst())
+ *
+ * @par Changeable Attributes
+ * \anchor neigh_changeable
+ * - state (rtnl_neigh_set_state())
+ * - link layer address (rtnl_neigh_set_lladdr())
+ *
+ * @par Required Caches for Dumping
+ * In order to dump neighbour attributes you must provide the following
+ * caches via nl_cache_provide()
+ * - link cache holding all links
+ *
+ * @par TODO
+ * - Document proxy settings
+ * - Document states and their influence
+ *
+ * @par 1) Retrieving information about configured neighbours
+ * @code
+ * // The first step is to retrieve a list of all available neighbour within
+ * // the kernel and put them into a cache.
+ * struct nl_cache *cache = rtnl_neigh_alloc_cache(sk);
+ *
+ * // Neighbours can then be looked up by the interface and destination
+ * // address:
+ * struct rtnl_neigh *neigh = rtnl_neigh_get(cache, ifindex, dst_addr);
+ *
+ * // After successful usage, the object must be given back to the cache
+ * rtnl_neigh_put(neigh);
+ * @endcode
+ *
+ * @par 2) Adding new neighbours
+ * @code
+ * // Allocate an empty neighbour handle to be filled out with the attributes
+ * // of the new neighbour.
+ * struct rtnl_neigh *neigh = rtnl_neigh_alloc();
+ *
+ * // Fill out the attributes of the new neighbour
+ * rtnl_neigh_set_ifindex(neigh, ifindex);
+ * rtnl_neigh_set_dst(neigh, dst_addr);
+ * rtnl_neigh_set_state(neigh, rtnl_neigh_str2state("permanent"));
+ *
+ * // Build the netlink message and send it to the kernel, the operation will
+ * // block until the operation has been completed. Alternatively the required
+ * // netlink message can be built using rtnl_neigh_build_add_request()
+ * // to be sent out using nl_send_auto_complete().
+ * rtnl_neigh_add(sk, neigh, NLM_F_CREATE);
+ *
+ * // Free the memory
+ * rtnl_neigh_put(neigh);
+ * @endcode
+ *
+ * @par 3) Deleting an existing neighbour
+ * @code
+ * // Allocate an empty neighbour object to be filled out with the attributes
+ * // matching the neighbour to be deleted. Alternatively a fully equipped
+ * // neighbour object out of a cache can be used instead.
+ * struct rtnl_neigh *neigh = rtnl_neigh_alloc();
+ *
+ * // Neighbours are uniquely identified by their interface index and
+ * // destination address, you may fill out other attributes but they
+ * // will have no influence.
+ * rtnl_neigh_set_ifindex(neigh, ifindex);
+ * rtnl_neigh_set_dst(neigh, dst_addr);
+ *
+ * // Build the netlink message and send it to the kernel, the operation will
+ * // block until the operation has been completed. Alternatively the required
+ * // netlink message can be built using rtnl_neigh_build_delete_request()
+ * // to be sent out using nl_send_auto_complete().
+ * rtnl_neigh_delete(sk, neigh, 0);
+ *
+ * // Free the memory
+ * rtnl_neigh_put(neigh);
+ * @endcode
+ *
+ * @par 4) Changing neighbour attributes
+ * @code
+ * // Allocate an empty neighbour object to be filled out with the attributes
+ * // matching the neighbour to be changed and the new parameters. Alternatively
+ * // a fully equipped modified neighbour object out of a cache can be used.
+ * struct rtnl_neigh *neigh = rtnl_neigh_alloc();
+ *
+ * // Identify the neighbour to be changed by its interface index and
+ * // destination address
+ * rtnl_neigh_set_ifindex(neigh, ifindex);
+ * rtnl_neigh_set_dst(neigh, dst_addr);
+ *
+ * // The link layer address may be modified, if so it is wise to change
+ * // its state to "permanent" in order to avoid having it overwritten.
+ * rtnl_neigh_set_lladdr(neigh, lladdr);
+ *
+ * // Secondly the state can be modified allowing normal neighbours to be
+ * // converted into permanent entries or to manually confirm a neighbour.
+ * rtnl_neigh_set_state(neigh, state);
+ *
+ * // Build the netlink message and send it to the kernel, the operation will
+ * // block until the operation has been completed. Alternatively the required
+ * // netlink message can be built using rtnl_neigh_build_change_request()
+ * // to be sent out using nl_send_auto_complete().
+ * rtnl_neigh_add(sk, neigh, NLM_F_REPLACE);
+ *
+ * // Free the memory
+ * rtnl_neigh_put(neigh);
+ * @endcode

+ * @par Qdisc Handles
+ * In general, qdiscs are identified by the major part of a traffic control
+ * handle (the upper 16 bits). A few special values exist though:
+ * - \c TC_H_ROOT: root qdisc (directly attached to the device)
+ * - \c TC_H_INGRESS: ingress qdisc (directly attached to the device)
+ * - \c TC_H_UNSPEC: unspecified qdisc (no reference)
+ *
+ * @par 1) Adding a Qdisc
+ * @code
+ * // Allocate a new empty qdisc to be filled out
+ * struct rtnl_qdisc *qdisc = rtnl_qdisc_alloc();
+ *
+ * // ... specify the kind of the Qdisc
+ * rtnl_qdisc_set_kind(qdisc, "pfifo");
+ *
+ * // Specify the device the qdisc should be attached to
+ * rtnl_qdisc_set_ifindex(qdisc, ifindex);
+ *
+ * // ... specify the parent qdisc
+ * rtnl_qdisc_set_parent(qdisc, TC_H_ROOT);
+ *
+ * // Specifying the handle is not required but makes reidentifying easier
+ * // and may help to avoid adding a qdisc twice.
+ * rtnl_qdisc_set_handle(qdisc, 0x000A0000);
+ *
+ * // Now on to specify the qdisc specific options, see the relevant qdisc
+ * // modules for documentation, in this example we set the upper limit of
+ * // the packet fifo qdisc to 64
+ * rtnl_qdisc_fifo_set_limit(qdisc, 64);
+ *
+ * rtnl_qdisc_add(handle, qdisc, NLM_R_REPLACE);
+ *
+ * // Free up the memory
+ * rtnl_qdisc_put(qdisc);
+ * @endcode
+ *
+ * @par 2) Deleting a Qdisc
+ * @code
+ * // Allocate a new empty qdisc to be filled out with the parameters
+ * // specifying the qdisc to be deleted. Alternatively a fully equiped
+ * // Qdisc object from a cache can be used.
+ * struct rtnl_qdisc *qdisc = rtnl_qdisc_alloc();
+ *
+ * // The interface index of the device the qdisc is on and the parent handle
+ * // are the least required fields to be filled out.
+ * // Note: Specify TC_H_ROOT or TC_H_INGRESS as parent handle to delete the
+ * // root respectively root ingress qdisc.
+ * rtnl_qdisc_set_ifindex(qdisc, ifindex);
+ * rtnl_qdisc_set_parent(qdisc, parent_handle);
+ *
+ * // If required for identification, the handle can be specified as well.
+ * rtnl_qdisc_set_handle(qdisc, qdisc_handle);
+ *
+ * // Not required but maybe helpful as sanity check, the kind of the qdisc
+ * // can be specified to avoid mistakes.
+ * rtnl_qdisc_set_kind(qdisc, "pfifo");
+ *
+ * // Finally delete the qdisc with rtnl_qdisc_delete(), alternatively
+ * // rtnl_qdisc_build_delete_request() can be invoked to generate an
+ * // appropritate netlink message to send out.
+ * rtnl_qdisc_delete(handle, qdisc);
