+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 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

+Here are a few quick points about DECnet support...
+
+ o iproute2 is the tool of choice for configuring the DECnet support for
+ Linux. For many features, it is the only tool which can be used to
+ configure them.
+
+ o No name resolution is available as yet, all addresses must be
+ entered numerically.
+
+ o Remember to set the hardware address of the interface using:
+
+ ip link set ethX address xx:xx:xx:xx:xx:xx
+ (where xx:xx:xx:xx:xx:xx is the MAC address for your DECnet node
+ address)
+
+ if your Ethernet card won't listen to more than one unicast
+ mac address at once. If the Linux DECnet stack doesn't talk to
+ any other DECnet nodes, then check this with tcpdump and if its
+ a problem, change the mac address (but do this _before_ starting
+ any other network protocol on the interface)
+
+ o Whilst you can use ip addr add to add more than one DECnet address to an
+ interface, don't expect addresses which are not the same as the
+ kernels node address to work properly with 2.4 kernels. This should
+ be fine with 2.6 kernels as the routing code has been extensively
+ modified and improved.
+
+ o The DECnet support is currently self contained. It does not depend on
+ the libdnet library.

+I. About the distribution tables
+
+The table used for "synthesizing" the distribution is essentially a scaled,
+translated, inverse to the cumulative distribution function.
+
+Here's how to think about it: Let F() be the cumulative distribution
+function for a probability distribution X. We'll assume we've scaled
+things so that X has mean 0 and standard deviation 1, though that's not
+so important here. Then:
+
+ F(x) = P(X <= x) = \int_{-inf}^x f
+
+where f is the probability density function.
+
+F is monotonically increasing, so has an inverse function G, with range
+0 to 1. Here, G(t) = the x such that P(X <= x) = t. (In general, G may
+have singularities if X has point masses, i.e., points x such that
+P(X = x) > 0.)
+
+Now we create a tabular representation of G as follows: Choose some table
+size N, and for the ith entry, put in G(i/N). Let's call this table T.
+
+The claim now is, I can create a (discrete) random variable Y whose
+distribution has the same approximate "shape" as X, simply by letting
+Y = T(U), where U is a discrete uniform random variable with range 1 to N.
+To see this, it's enough to show that Y's cumulative distribution function,
+(let's call it H), is a discrete approximation to F. But
+
+ H(x) = P(Y <= x)
+ = (# of entries in T <= x) / N -- as Y chosen uniformly from T
+ = i/N, where i is the largest integer such that G(i/N) <= x
+ = i/N, where i is the largest integer such that i/N <= F(x)
+ -- since G and F are inverse functions (and F is
+ increasing)
+ = floor(N*F(x))/N
+
+as desired.
+
+II. How to create distribution tables (in theory)
+
+How can we create this table in practice? In some cases, F may have a
+simple expression which allows evaluating its inverse directly. The
+Pareto distribution is one example of this. In other cases, and
+especially for matching an experimentally observed distribution, it's
+easiest simply to create a table for F and "invert" it. Here, we give
+a concrete example, namely how the new "experimental" distribution was
+created.
+
+1. Collect enough data points to characterize the distribution. Here, I
+collected 25,000 "ping" roundtrip times to a "distant" point (time.nist.gov).
+That's far more data than is really necessary, but it was fairly painless to
+collect it, so...
+
+2. Normalize the data so that it has mean 0 and standard deviation 1.
+
+3. Determine the cumulative distribution. The code I wrote creates a table
+covering the range -10 to +10, with granularity .00005. Obviously, this
+is absurdly over-precise, but since it's a one-time only computation, I
+figured it hardly mattered.
+
+4. Invert the table: for each table entry F(x) = y, make the y*TABLESIZE
+(here, 4096) entry be x*TABLEFACTOR (here, 8192). This creates a table
+for the ("normalized") inverse of size TABLESIZE, covering its domain 0
+to 1 with granularity 1/TABLESIZE. Note that even with the granularity
+used in creating the table for F, it's possible not all the entries in
+the table for G will be filled in. So, make a pass through the
+inverse's table, filling in any missing entries by linear interpolation.
+
+III. How to create distribution tables (in practice)
+
+If you want to do all this yourself, I've provided several tools to help:
+
+1. maketable does the steps 2-4 above, and then generates the appropriate
+header file. So if you have your own time distribution, you can generate
+the header simply by:
+
+ maketable < time.values > header.h
+
+2. As explained in the other README file, the somewhat sleazy way I have
+of generating correlated values needs correction. You can generate your
+own correction tables by compiling makesigtable and makemutable with
+your header file. Check the Makefile to see how this is done.
+
+3. Warning: maketable, makesigtable and especially makemutable do
+enormous amounts of floating point arithmetic. Don't try running
+these on an old 486. (NIST Net itself will run fine on such a
+system, since in operation, it just needs to do a few simple integral
+calculations. But getting there takes some work.)
+
+4. The tables produced are all normalized for mean 0 and standard
+deviation 1. How do you know what values to use for real? Here, I've
+provided a simple "stats" utility. Give it a series of floating point
+values, and it will return their mean (mu), standard deviation (sigma),
+and correlation coefficient (rho). You can then plug these values
+directly into NIST Net.

+
+Micro-manual how to start it the first time
+-------------------------------------------
+
+A. Attach CBQ to eth1:
+
+tc qdisc add dev eth1 root handle 1: cbq bandwidth 10Mbit allot 1514 cell 8 \
+avpkt 1000 mpu 64
+
+B. Add root class:
+
+tc class add dev eth1 parent 1:0 classid 1:1 cbq bandwidth 10Mbit rate 10Mbit \
+allot 1514 cell 8 weight 1Mbit prio 8 maxburst 20 avpkt 1000
+
+C. Add default interactive class:
+
+tc class add dev eth1 parent 1:1 classid 1:2 cbq bandwidth 10Mbit rate 1Mbit \
+allot 1514 cell 8 weight 100Kbit prio 3 maxburst 20 avpkt 1000 split 1:0 \
+defmap c0
+
+D. Add default class:
+
+tc class add dev eth1 parent 1:1 classid 1:3 cbq bandwidth 10Mbit rate 8Mbit \
+allot 1514 cell 8 weight 800Kbit prio 7 maxburst 20 avpkt 1000 split 1:0 \
+defmap 3f
+
+etc. etc. etc. Well, it is enough to start 8) The rest can be guessed 8)
+Look also at more elaborated example, ready to start rsvpd,
+in rsvp/cbqinit.eth1.
+
+
+Terminology and advices about setting CBQ parameters may be found in Sally Floyd
+papers.
+
+
+Pairs X:Y are class handles, X:0 are qdisc handles.
+weight should be proportional to rate for leaf classes
+(I choosed it ten times less, but it is not necessary)
+
+defmap is bitmap of logical priorities served by this class.
+
+E. Another qdiscs are simpler. F.e. let's join TBF on class 1:2
+
+tc qdisc add dev eth1 parent 1:2 tbf rate 64Kbit buffer 5Kb/8 limit 10Kb
+
+F. Look at all that we created:
+
+tc qdisc ls dev eth1
+tc class ls dev eth1
+
+G. Install "route" classifier on root of cbq and map destination from realm
+1 to class 1:2
+
+tc filter add dev eth1 parent 1:0 protocol ip prio 100 route to 1 classid 1:2
+
+H. Assign routes to 10.11.12.0/24 to realm 1
+
+ip route add 10.11.12.0/24 dev eth1 via whatever realm 1
+
+etc. The same thing can be made with rules.
+I still did not test ipchains, but they should work too.
+
+
+Setup and code example of BPF classifier and action can be found under
+examples/bpf/, which should explain everything for getting started.
+
+
+Setup of rsvp and u32 classifiers is more hairy.
+If you read RSVP specs, you will understand how rsvp classifier
+works easily. What's about u32... That's example:
+
+
+#! /bin/sh
+
+TC=/home/root/tc
+
+# Setup classifier root on eth1 root (it is cbq)
+$TC filter add dev eth1 parent 1:0 prio 5 protocol ip u32
+
+# Create hash table of 256 slots with ID 1:
+$TC filter add dev eth1 parent 1:0 prio 5 handle 1: u32 divisor 256
+
+# Add to 6th slot of hash table rule to select tcp/telnet to 193.233.7.75
+# direct it to class 1:4 and prescribe to fall to best effort,
+# if traffic violate TBF (32kbit,5K)
+$TC filter add dev eth1 parent 1:0 prio 5 u32 ht 1:6: \

+lnstat - linux networking statistics
+(C) 2004 Harald Welte <laforge@gnumonks.org
+======================================================================
+
+This tool is a generalized and more feature-complete replacement for the old
+'rtstat' program.
+
+In addition to routing cache statistics, it supports any kind of statistics
+the linux kernel exports via a file in /proc/net/stat. In a stock 2.6.9
+kernel, this is
+ per-protocol neighbour cache statistics
+ (ipv4, ipv6, atm, decnet)
+ routing cache statistics
+ (ipv4)
+ connection tracking statistics
+ (ipv4)
+
+Please note that lnstat will adopt to any additional statistics that might be
+added to the kernel at some later point
+
+I personally always like examples more than any reference documentation, so I
+list the following examples. If somebody wants to do a manpage, feel free
+to send me a patch :)
+
+EXAMPLES:
+
+In order to get a list of supported statistics files, you can run
+
+ lnstat -d
+
+It will display something like
+
+/proc/net/stat/arp_cache:
+ 1: entries
+ 2: allocs
+ 3: destroys
+[...]
+/proc/net/stat/rt_cache:
+ 1: entries
+ 2: in_hit
+ 3: in_slow_tot
+
+You can now select the files/keys you are interested by something like
+
+ lnstat -k arp_cache:entries,rt_cache:in_hit,arp_cache:destroys
+
+arp_cach|rt_cache|arp_cach|
+ entries| in_hit|destroys|
+ 6| 6| 0|
+ 6| 0| 0|
+ 6| 2| 0|
+
+
+You can specify the interval (e.g. 10 seconds) by:
+
+ lnstat -i 10
+
+You can specify to only use one particular statistics file:
+
+ lnstat -f ip_conntrack
+
+You can specify individual field widths
+
+ lnstat -k arp_cache:entries,rt_cache:entries -w 20,8
+
+You can specify not to print a header at all
+
+ lnstat -s 0
+
+You can specify to print a header only at start of the program
+
+ lnstat -s 1
+
+You can specify to print a header at start and every 20 lines:
+
+ lnstat -s 20
+
+You can specify the number of samples you want to take (e.g. 5):
+
+ lnstat -c 5
+

+\section{Introduction.}
+
+Every IPv6 packet carries 28 bits of flow information. RFC2460 splits
+these bits to two fields: 8 bits of traffic class (or DS field, if you
+prefer this term) and 20 bits of flow label. Currently there exist
+no well-defined API to manage IPv6 flow information. In this document
+I describe an attempt to design the API for Linux-2.2 IPv6 stack.
+
+\vskip 1mm
+
+The API must solve the following tasks:
+
+\begin{enumerate}
+
+\item To allow user to set traffic class bits.
+
+\item To allow user to read traffic class bits of received packets.
+This feature is not so useful as the first one, however it will be
+necessary f.e.\ to implement ECN [RFC2481] for datagram oriented services
+or to implement receiver side of SRP or another end-to-end protocol
+using traffic class bits.
+
+\item To assign flow labels to packets sent by user.
+
+\item To get flow labels of received packets. I do not know
+any applications of this feature, but it is possible that receiver will
+want to use flow labels to distinguish sub-flows.
+
+\item To allocate flow labels in the way, compliant to RFC2460. Namely:
+
+\begin{itemize}
+\item
+Flow labels must be uniformly distributed (pseudo-)random numbers,
+so that any subset of 20 bits can be used as hash key.
+
+\item
+Flows with coinciding source address and flow label must have identical
+destination address and not-fragmentable extensions headers (i.e.\
+hop by hop options and all the headers up to and including routing header,
+if it is present.)
+
+\begin{NB}
+There is a hole in specs: some hop-by-hop options can be
+defined only on per-packet base (f.e.\ jumbo payload option).
+Essentially, it means that such options cannot present in packets
+with flow labels.
+\end{NB}
+\begin{NB}
+NB notes here and below reflect only my personal opinion,
+they should be read with smile or should not be read at all :-).
+\end{NB}
+
+
+\item
+Flow labels have finite lifetime and source is not allowed to reuse
+flow label for another flow within the maximal lifetime has expired,
+so that intermediate nodes will be able to invalidate flow state before
+the label is taken over by another flow.
+Flow state, including lifetime, is propagated along datagram path
+by some application specific methods
+(f.e.\ in RSVP PATH messages or in some hop-by-hop option).
+
+
+\end{itemize}
+
+\end{enumerate}
+
+\section{Sending/receiving flow information.}
+
+\paragraph{Discussion.}
+\addcontentsline{toc}{subsection}{Discussion}
+It was proposed (Where? I do not remember any explicit statement)
+to solve the first four tasks using
+\verb|sin6_flowinfo| field added to \verb|struct| \verb|sockaddr_in6|
+(see RFC2553).
+
+\begin{NB}
+ This method is difficult to consider as reasonable, because it
+ puts additional overhead to all the services, despite of only
+ very small subset of them (none, to be more exact) really use it.
+ It contradicts both to IETF spirit and the letter. Before RFC2553
+ one justification existed, IPv6 address alignment left 4 byte
+ hole in \verb|sockaddr_in6| in any case. Now it has no justification.
+\end{NB}
+
+We have two problems with this method. The first one is common for all OSes:
+if \verb|recvmsg()| initializes \verb|sin6_flowinfo| to flow info
+of received packet, we loose one very important property of BSD socket API,
+namely, we are not allowed to use received address for reply directly
+and have to mangle it, even if we are not interested in flowinfo subtleties.
+
+\begin{NB}
+ RFC2553 adds new requirement: to clear \verb|sin6_flowinfo|.
+ Certainly, it is not solution but rather attempt to force applications
+ to make unnecessary work. Well, as usually, one mistake in design
+ is followed by attempts to patch the hole and more mistakes...
+\end{NB}
+
+Another problem is Linux specific. Historically Linux IPv6 did not
+initialize \verb|sin6_flowinfo| at all, so that, if kernel does not
+support flow labels, this field is not zero, but a random number.
+Some applications also did not take care about it.
+
+\begin{NB}
+Following RFC2553 such applications can be considered as broken,
+but I still think that they are right: clearing all the address
+before filling known fields is robust but stupid solution.
+Useless wasting CPU cycles and
+memory bandwidth is not a good idea. Such patches are acceptable
+as temporary hacks, but not as standard of the future.
+\end{NB}
+
+
+\paragraph{Implementation.}
+\addcontentsline{toc}{subsection}{Implementation}
+By default Linux IPv6 does not read \verb|sin6_flowinfo| field
+assuming that common applications are not obliged to initialize it
+and are permitted to consider it as pure alignment padding.
+In order to tell kernel that application
+is aware of this field, it is necessary to set socket option
+\verb|IPV6_FLOWINFO_SEND|.
+
+\begin{verbatim}
+ int on = 1;
+ setsockopt(sock, SOL_IPV6, IPV6_FLOWINFO_SEND,
+ (void*)&on, sizeof(on));
+\end{verbatim}
+
+Linux kernel never fills \verb|sin6_flowinfo| field, when passing
+message to user space, though the kernels which support flow labels
+initialize it to zero. If user wants to get received flowinfo, he
+will set option \verb|IPV6_FLOWINFO| and after this he will receive
+flowinfo as ancillary data object of type \verb|IPV6_FLOWINFO|
+(cf.\ RFC2292).
+
+\begin{verbatim}
+ int on = 1;
+ setsockopt(sock, SOL_IPV6, IPV6_FLOWINFO, (void*)&on, sizeof(on));
+\end{verbatim}
+
+Flowinfo received and latched by a connected TCP socket also may be fetched
+with \verb|getsockopt()| \verb|IPV6_PKTOPTIONS| together with
+another optional information.
+
+Besides that, in the spirit of RFC2292 the option \verb|IPV6_FLOWINFO|
+may be used as alternative way to send flowinfo with \verb|sendmsg()| or
+to latch it with \verb|IPV6_PKTOPTIONS|.
+
+\paragraph{Note about IPv6 options and destination address.}
+\addcontentsline{toc}{subsection}{IPv6 options and destination address}
+If \verb|sin6_flowinfo| does contain not zero flow label,
+destination address in \verb|sin6_addr| and non-fragmentable
+extension headers are ignored. Instead, kernel uses the values
+cached at flow setup (see below). However, for connected sockets
+kernel prefers the values set at connection time.
+
+\paragraph{Example.}
+\addcontentsline{toc}{subsection}{Example}
+After setting socket option \verb|IPV6_FLOWINFO|
+flowlabel and DS field are received as ancillary data object
+of type \verb|IPV6_FLOWINFO| and level \verb|SOL_IPV6|.
+In the cases when it is convenient to use \verb|recvfrom(2)|,
+it is possible to replace library variant with your own one,
+sort of:
+
+\begin{verbatim}
+#include <sys/socket.h>
+#include <netinet/in6.h>
+
+size_t recvfrom(int fd, char *buf, size_t len, int flags,
+ struct sockaddr *addr, int *addrlen)
+{
+ size_t cc;
+ char cbuf[128];
+ struct cmsghdr *c;
+ struct iovec iov = { buf, len };
+ struct msghdr msg = { addr, *addrlen,
+ &iov, 1,
+ cbuf, sizeof(cbuf),
+ 0 };
+
+ cc = recvmsg(fd, &msg, flags);
+ if (cc < 0)
+ return cc;
+ ((struct sockaddr_in6*)addr)->sin6_flowinfo = 0;
+ *addrlen = msg.msg_namelen;
+ for (c=CMSG_FIRSTHDR(&msg); c; c = CMSG_NEXTHDR(&msg, c)) {
+ if (c->cmsg_level != SOL_IPV6 ||
+ c->cmsg_type != IPV6_FLOWINFO)
+ continue;
+ ((struct sockaddr_in6*)addr)->sin6_flowinfo = *(__u32*)CMSG_DATA(c);
+ }
+ return cc;
+}
+\end{verbatim}
+
+
+
+\section{Flow label management.}
+
+\paragraph{Discussion.}
+\addcontentsline{toc}{subsection}{Discussion}
+Requirements of RFC2460 are pretty tough. Particularly, lifetimes
+longer than boot time require to store allocated labels at stable
+storage, so that the full implementation necessarily includes user space flow
+label manager. There are at least three different approaches:
+
+\begin{enumerate}
+\item {\bf ``Cooperative''. } We could leave flow label allocation wholly
+to user space. When user needs label he requests manager directly. The approach
+is valid, but as any ``cooperative'' approach it suffers of security problems.
+
+\begin{NB}
+One idea is to disallow not privileged user to allocate flow
+labels, but instead to pass the socket to manager via \verb|SCM_RIGHTS|
+control message, so that it will allocate label and assign it to socket
+itself. Hmm... the idea is interesting.
+\end{NB}
+
+\item {\bf ``Indirect''.} Kernel redirects requests to user level daemon
+and does not install label until the daemon acknowledged the request.
+The approach is the most promising, it is especially pleasant to recognize
+parallel with IPsec API [RFC2367,Craig]. Actually, it may share API with
+IPsec.
+
+\item {\bf ``Stupid''.} To allocate labels in kernel space. It is the simplest
+method, but it suffers of two serious flaws: the first,
+we cannot lease labels with lifetimes longer than boot time, the second,
+it is sensitive to DoS attacks. Kernel have to remember all the obsolete
+labels until their expiration and malicious user may fastly eat all the
+flow label space.
+
+\end{enumerate}
+
+Certainly, I choose the most ``stupid'' method. It is the cheapest one
+for implementor (i.e.\ me), and taking into account that flow labels
+still have no serious applications it is not useful to work on more
+advanced API, especially, taking into account that eventually we
+will get it for no fee together with IPsec.
+
+
+\paragraph{Implementation.}
+\addcontentsline{toc}{subsection}{Implementation}
+Socket option \verb|IPV6_FLOWLABEL_MGR| allows to
+request flow label manager to allocate new flow label, to reuse
+already allocated one or to delete old flow label.
+Its argument is \verb|struct| \verb|in6_flowlabel_req|:
+
+\begin{verbatim}
+struct in6_flowlabel_req
+{
+ struct in6_addr flr_dst;
+ __u32 flr_label;
+ __u8 flr_action;
+ __u8 flr_share;
+ __u16 flr_flags;
+ __u16 flr_expires;
+ __u16 flr_linger;
+ __u32 __flr_reserved;
+ /* Options in format of IPV6_PKTOPTIONS */
+};
+\end{verbatim}
+
+\begin{itemize}
+
+\item \verb|dst| is IPv6 destination address associated with the label.
+
+\item \verb|label| is flow label value in network byte order. If it is zero,
+kernel will allocate new pseudo-random number. Otherwise, kernel will try
+to lease flow label ordered by user. In this case, it is user task to provide
+necessary flow label randomness.
+
+\item \verb|action| is requested operation. Currently, only three operations
+are defined:
+
+\begin{verbatim}
+#define IPV6_FL_A_GET 0 /* Get flow label */
+#define IPV6_FL_A_PUT 1 /* Release flow label */
+#define IPV6_FL_A_RENEW 2 /* Update expire time */
+\end{verbatim}
+
+\item \verb|flags| are optional modifiers. Currently
+only \verb|IPV6_FL_A_GET| has modifiers:
+
+\begin{verbatim}
+#define IPV6_FL_F_CREATE 1 /* Allowed to create new label */
+#define IPV6_FL_F_EXCL 2 /* Do not create new label */
+\end{verbatim}
+
+
+\item \verb|share| defines who is allowed to reuse the same flow label.
+
+\begin{verbatim}
+#define IPV6_FL_S_NONE 0 /* Not defined */
+#define IPV6_FL_S_EXCL 1 /* Label is private */
+#define IPV6_FL_S_PROCESS 2 /* May be reused by this process */
+#define IPV6_FL_S_USER 3 /* May be reused by this user */
+#define IPV6_FL_S_ANY 255 /* Anyone may reuse it */
+\end{verbatim}
+
+\item \verb|linger| is time in seconds. After the last user releases flow
+label, it will not be reused with different destination and options at least
+during this time. If \verb|share| is not \verb|IPV6_FL_S_EXCL| the label
+still can be shared by another sockets. Current implementation does not allow
+unprivileged user to set linger longer than 60 sec.
+
+\item \verb|expires| is time in seconds. Flow label will be kept at least
+for this time, but it will not be destroyed before user released it explicitly
+or closed all the sockets using it. Current implementation does not allow
+unprivileged user to set timeout longer than 60 sec. Proviledged applications
+MAY set longer lifetimes, but in this case they MUST save allocated
+labels at stable storage and restore them back after reboot before the first
+application allocates new flow.
+
+\end{itemize}
+
+This structure is followed by optional extension headers associated
+with this flow label in format of \verb|IPV6_PKTOPTIONS|. Only
+\verb|IPV6_HOPOPTS|, \verb|IPV6_RTHDR| and, if \verb|IPV6_RTHDR| presents,
+\verb|IPV6_DSTOPTS| are allowed.
+
+\paragraph{Example.}
+\addcontentsline{toc}{subsection}{Example}
+ The function \verb|get_flow_label| allocates
+private flow label.
+
+\begin{verbatim}
+int get_flow_label(int fd, struct sockaddr_in6 *dst, __u32 fl)
+{
+ int on = 1;
+ struct in6_flowlabel_req freq;
+
+ memset(&freq, 0, sizeof(freq));
+ freq.flr_label = htonl(fl);
+ freq.flr_action = IPV6_FL_A_GET;
+ freq.flr_flags = IPV6_FL_F_CREATE | IPV6_FL_F_EXCL;
+ freq.flr_share = IPV6_FL_S_EXCL;
+ memcpy(&freq.flr_dst, &dst->sin6_addr, 16);
+ if (setsockopt(fd, SOL_IPV6, IPV6_FLOWLABEL_MGR,
+ &freq, sizeof(freq)) == -1) {
+ perror ("can't lease flowlabel");
+ return -1;
+ }
+ dst->sin6_flowinfo |= freq.flr_label;
+
+ if (setsockopt(fd, SOL_IPV6, IPV6_FLOWINFO_SEND,
+ &on, sizeof(on)) == -1) {
+ perror ("can't send flowinfo");
+
+ freq.flr_action = IPV6_FL_A_PUT;
+ setsockopt(fd, SOL_IPV6, IPV6_FLOWLABEL_MGR,
+ &freq, sizeof(freq));
+ return -1;
+ }
+ return 0;
+}
+\end{verbatim}
+
+A bit more complicated example using routing header can be found
+in \verb|ping6| utility (\verb|iputils| package). Linux rsvpd backend
+contains an example of using operation \verb|IPV6_FL_A_RENEW|.
+
+\paragraph{Listing flow labels.}
+\addcontentsline{toc}{subsection}{Listing flow labels}
+List of currently allocated
+flow labels may be read from \verb|/proc/net/ip6_flowlabel|.
+
+\begin{verbatim}
+Label S Owner Users Linger Expires Dst Opt
+A1BE5 1 0 0 6 3 3ffe2400000000010a0020fffe71fb30 0
+\end{verbatim}
+
+\begin{itemize}
+\item \verb|Label| is hexadecimal flow label value.
+\item \verb|S| is sharing style.
+\item \verb|Owner| is ID of creator, it is zero, pid or uid, depending on
+ sharing style.
+\item \verb|Users| is number of applications using the label now.
+\item \verb|Linger| is \verb|linger| of this label in seconds.
+\item \verb|Expires| is time until expiration of the label in seconds. It may
+ be negative, if the label is in use.
+\item \verb|Dst| is IPv6 destination address.
+\item \verb|Opt| is length of options, associated with the label. Option
+ data are not accessible.
+\end{itemize}
+
+
+\paragraph{Flow labels and RSVP.}
+\addcontentsline{toc}{subsection}{Flow labels and RSVP}
+RSVP daemon supports IPv6 flow labels
+without any modifications to standard ISI RAPI. Sender must allocate
+flow label, fill corresponding sender template and submit it to local rsvp
+daemon. rsvpd will check the label and start to announce it in PATH
+messages. Rsvpd on sender node will renew the flow label, so that it will not
+be reused before path state expires and all the intermediate
+routers and receiver purge flow state.
+
+\verb|rtap| utility is modified to parse flow labels. F.e.\ if user allocated
+flow label \verb|0xA1234|, he may write:
+
+\begin{verbatim}
+RTAP> sender 3ffe:2400::1/FL0xA1234 <Tspec>
+\end{verbatim}
+
+Receiver makes reservation with command:
+\begin{verbatim}
+RTAP> reserve ff 3ffe:2400::1/FL0xA1234 <Flowspec>
+\end{verbatim}

+<title>ARPD Daemon
+<author>Alexey Kuznetsov, <tt/kuznet@ms2.inr.ac.ru/
+<date>some_negative_number, 20 Sep 2001
+<abstract>
+<tt/arpd/ is daemon collecting gratuitous ARP information, saving
+it on local disk and feeding it to kernel on demand to avoid
+redundant broadcasting due to limited size of kernel ARP cache.
+</abstract>
+
+
+<p><bf/Description/
+
+<p>The format of the command is:
+
+<tscreen><verb>
+ arpd OPTIONS [ INTERFACE [ INTERFACE ... ] ]
+</verb></tscreen>
+
+<p> <tt/OPTIONS/ are:
+
+<itemize>
+
+<item><tt/-l/ - dump <tt/arpd/ database to stdout and exit. Output consists
+of three columns: interface index, IP address and MAC address.
+Negative entries for dead hosts are also shown, in this case MAC address
+is replaced by word <tt/FAILED/ followed by colon and time when the fact
+that host is dead was proven the last time.
+
+<item><tt/-f FILE/ - read and load <tt/arpd/ database from <tt/FILE/
+in text format similar dumped by option <tt/-l/. Exit after load,
+probably listing resulting database, if option <tt/-l/ is also given.
+If <tt/FILE/ is <tt/-/, <tt/stdin/ is read to get ARP table.
+
+<item><tt/-b DATABASE/ - location of database file. Default location is
+<tt>/var/lib/arpd/arpd.db</tt>.
+
+<item><tt/-a NUMBER/ - <tt/arpd/ not only passively listens ARP on wire, but
+also send brodcast queries itself. <tt/NUMBER/ is number of such queries
+to make before destination is considered as dead. When <tt/arpd/ is started
+as kernel helper (i.e. with <tt/app_solicit/ enabled in <tt/sysctl/
+or even with option <tt/-k/) without this option and still did not learn enough
+information, you can observe 1 second gaps in service. Not fatal, but
+not good.
+
+<item><tt/-k/ - suppress sending broadcast queries by kernel. It takes
+sense together with option <tt/-a/.
+
+<item><tt/-n TIME/ - timeout of negative cache. When resolution fails <tt/arpd/
+suppresses further attempts to resolve for this period. It makes sense
+only together with option <tt/-k/. This timeout should not be too much
+longer than boot time of a typical host not supporting gratuitous ARP.
+Default value is 60 seconds.
+
+<item><tt/-R RATE/ - maximal steady rate of broadcasts sent by <tt/arpd/
+in packets per second. Default value is 1.
+
+<item><tt/-B NUMBER/ - number of broadcasts sent by <tt/arpd/ back to back.
+Default value is 3. Together with option <tt/-R/ this option allows
+to police broadcasting not to exceed <tt/B+R*T/ over any interval
+of time <tt/T/.
+
+</itemize>
+
+<p><tt/INTERFACE/ is name of networking inteface to watch.
+If no interfaces given, <tt/arpd/ monitors all the interfaces.
+In this case <tt/arpd/ does not adjust <tt/sysctl/ parameters,
+it is supposed user does this himself after <tt/arpd/ is started.
+
+
+<p> Signals
+
+<p> <tt/arpd/ exits gracefully syncing database and restoring adjusted
+<tt/sysctl/ parameters, when receives <tt/SIGINT/ or <tt/SIGTERM/.
+<tt/SIGHUP/ syncs database to disk. <tt/SIGUSR1/ sends some statistics
+to <tt/syslog/. Effect of another signals is undefined, they may corrupt
+database and leave <tt/sysctl/ parameters in an unpredictable state.
+
+<p> Note
+
+<p> In order to <tt/arpd/ be able to serve as ARP resolver, kernel must be
+compiled with the option <tt/CONFIG_ARPD/ and, in the case when interface list
+is not given on command line, variable <tt/app_solicit/
+on interfaces of interest should be set in <tt>/proc/sys/net/ipv4/neigh/*</tt>.
+If this is not made <tt/arpd/ still collects gratuitous ARP information
+in its database.
+
+<p> Examples
+
+<enum>
+<item> Start <tt/arpd/ to collect gratuitous ARP, but not messing
+with kernel functionality:
+
+<tscreen><verb>
+ arpd -b /var/tmp/arpd.db
+</verb></tscreen>
+
+<item> Look at result after some time:
+
+<tscreen><verb>
+ killall arpd
+ arpd -l -b /var/tmp/arpd.db
+</verb></tscreen>
+
+<item> To enable kernel helper, leaving leading role to kernel:
+
+<tscreen><verb>
+ arpd -b /var/tmp/arpd.db -a 1 eth0 eth1
+</verb></tscreen>
+
+<item> Completely replace kernel resolution on interfaces <tt/eth0/
+and <tt/eth1/. In this case kernel still does unicast probing to
+validate entries, but all the broadcast activity is suppressed
+and made under authority of <tt/arpd/:
+
+<tscreen><verb>
+ arpd -b /var/tmp/arpd.db -a 3 -k eth0 eth1
+</verb></tscreen>
+
+This is mode which <tt/arpd/ is supposed to work normally.
+It is not default just to prevent occasional enabling of too aggressive
+mode occasionally.

+\section{About this document}
+
+This document presents a comprehensive description of the \verb|ip| utility
+from the \verb|iproute2| package. It is not a tutorial or user's guide.
+It is a {\em dictionary\/}, not explaining terms,
+but translating them into other terms, which may also be unknown to the reader.
+However, the document is self-contained and the reader, provided they have a
+basic networking background, will find enough information
+and examples to understand and configure Linux-2.2 IP and IPv6
+networking.
+
+This document is split into sections explaining \verb|ip| commands
+and options, decrypting \verb|ip| output and containing a few examples.
+More voluminous examples and some topics, which require more elaborate
+discussion, are in the appendix.
+
+The paragraphs beginning with NB contain side notes, warnings about
+bugs and design drawbacks. They may be skipped at the first reading.
+
+\section{{\tt ip} --- command syntax}
+
+The generic form of an \verb|ip| command is:
+\begin{verbatim}
+ip [ OPTIONS ] OBJECT [ COMMAND [ ARGUMENTS ]]
+\end{verbatim}
+where \verb|OPTIONS| is a set of optional modifiers affecting the
+general behaviour of the \verb|ip| utility or changing its output. All options
+begin with the character \verb|'-'| and may be used in either long or abbreviated
+forms. Currently, the following options are available:
+
+\begin{itemize}
+\item \verb|-V|, \verb|-Version|
+
+--- print the version of the \verb|ip| utility and exit.
+
+
+\item \verb|-s|, \verb|-stats|, \verb|-statistics|
+
+--- output more information. If the option
+appears twice or more, the amount of information increases.
+As a rule, the information is statistics or some time values.
+
+\item \verb|-d|, \verb|-details|
+
+--- output more detailed information.
+
+\item \verb|-f|, \verb|-family| followed by a protocol family
+identifier: \verb|inet|, \verb|inet6| or \verb|link|.
+
+--- enforce the protocol family to use. If the option is not present,
+the protocol family is guessed from other arguments. If the rest of the command
+line does not give enough information to guess the family, \verb|ip| falls back to the default
+one, usually \verb|inet| or \verb|any|. \verb|link| is a special family
+identifier meaning that no networking protocol is involved.
+
+\item \verb|-4|
+
+--- shortcut for \verb|-family inet|.
+
+\item \verb|-6|
+
+--- shortcut for \verb|-family inet6|.
+
+\item \verb|-0|
+
+--- shortcut for \verb|-family link|.
+
+
+\item \verb|-o|, \verb|-oneline|
+
+--- output each record on a single line, replacing line feeds
+with the \verb|'\'| character. This is convenient when you want to
+count records with \verb|wc| or to \verb|grep| the output. The trivial
+script \verb|rtpr| converts the output back into readable form.
+
+\item \verb|-r|, \verb|-resolve|
+
+--- use the system's name resolver to print DNS names instead of
+host addresses.
+
+\begin{NB}
+ Do not use this option when reporting bugs or asking for advice.
+\end{NB}
+\begin{NB}
+ \verb|ip| never uses DNS to resolve names to addresses.
+\end{NB}
+
+\item \verb|-b|, \verb|-batch FILE|
+
+--- read commands from provided file or standart input and invoke them.
+First failure will cause termination of \verb|ip|.
+In batch \verb|FILE| everything which begins with \verb|#| symbol is
+ignored and can be used for comments.
+\paragraph{Example:}
+\begin{verbatim}
+kuznet@kaiser $ cat /tmp/ip_batch.ip
+# This is a comment
+tuntap add mode tap tap1 # This is an another comment
+link set up dev tap1
+addr add 10.0.0.1/24 dev tap1
+kuznet@kaiser $ sudo ip -b /tmp/ip_batch.ip
+\end{verbatim}
+or from standart input:
+\begin{verbatim}
+kuznet@kaiser $ cat /tmp/ip_batch.ip | sudo ip -b -
+\end{verbatim}
+
+\item \verb|-force|
+
+--- don't terminate ip on errors in batch mode.
+If there were any errors during execution of the commands,
+the application return code will be non zero.
+
+\item \verb|-l|, \verb|-loops COUNT|
+
+--- specify maximum number of loops the 'ip addr flush' logic will attempt
+before giving up. The default is 10. Zero (0) means loop until all
+addresses are removed.
+
+\end{itemize}
+
+\verb|OBJECT| is the object to manage or to get information about.
+The object types currently understood by \verb|ip| are:
+
+\begin{itemize}
+\item \verb|link| --- network device
+\item \verb|address| --- protocol (IP or IPv6) address on a device
+\item \verb|neighbour| --- ARP or NDISC cache entry
+\item \verb|route| --- routing table entry
+\item \verb|rule| --- rule in routing policy database
+\item \verb|maddress| --- multicast address
+\item \verb|mroute| --- multicast routing cache entry
+\item \verb|tunnel| --- tunnel over IP
+\end{itemize}
+
+Again, the names of all objects may be written in full or
+abbreviated form, f.e.\ \verb|address| is abbreviated as \verb|addr|
+or just \verb|a|.
+
+\verb|COMMAND| specifies the action to perform on the object.
+The set of possible actions depends on the object type.
+As a rule, it is possible to \verb|add|, \verb|delete| and
+\verb|show| (or \verb|list|) objects, but some objects
+do not allow all of these operations or have some additional commands.
+The \verb|help| command is available for all objects. It prints
+out a list of available commands and argument syntax conventions.
+
+If no command is given, some default command is assumed.
+Usually it is \verb|list| or, if the objects of this class
+cannot be listed, \verb|help|.
+
+\verb|ARGUMENTS| is a list of arguments to the command.
+The arguments depend on the command and object. There are two types of arguments:
+{\em flags\/}, consisting of a single keyword, and {\em parameters\/},
+consisting of a keyword followed by a value. For convenience,
+each command has some {\em default parameter\/}
+which may be omitted. F.e.\ parameter \verb|dev| is the default
+for the {\tt ip link} command, so {\tt ip link ls eth0} is equivalent
+to {\tt ip link ls dev eth0}.
+In the command descriptions below such parameters
+are distinguished with the marker: ``(default)''.
+
+Almost all keywords may be abbreviated with several first (or even single)
+letters. The shortcuts are convenient when \verb|ip| is used interactively,
+but they are not recommended in scripts or when reporting bugs
+or asking for advice. ``Officially'' allowed abbreviations are listed
+in the document body.
+
+
+
+\section{{\tt ip} --- error messages}
+
+\verb|ip| may fail for one of the following reasons:
+
+\begin{itemize}
+\item
+A syntax error on the command line: an unknown keyword, incorrectly formatted
+IP address {\em et al\/}. In this case \verb|ip| prints an error message
+and exits. As a rule, the error message will contain information
+about the reason for the failure. Sometimes it also prints a help page.
+
+\item
+The arguments did not pass verification for self-consistency.
+
+\item
+\verb|ip| failed to compile a kernel request from the arguments
+because the user didn't give enough information.
+
+\item
+The kernel returned an error to some syscall. In this case \verb|ip|
+prints the error message, as it is output with \verb|perror(3)|,
+prefixed with a comment and a syscall identifier.
+
+\item
+The kernel returned an error to some RTNETLINK request.
+In this case \verb|ip| prints the error message, as it is output
+with \verb|perror(3)| prefixed with ``RTNETLINK answers:''.
+
+\end{itemize}
+
+All the operations are atomic, i.e.\
+if the \verb|ip| utility fails, it does not change anything
+in the system. One harmful exception is \verb|ip link| command
+(Sec.\ref{IP-LINK}, p.\pageref{IP-LINK}),
+which may change only some of the device parameters given
+on command line.
+
+It is difficult to list all the error messages (especially
+syntax errors). However, as a rule, their meaning is clear
+from the context of the command.
+
+The most common mistakes are:
+
+\begin{enumerate}
+\item Netlink is not configured in the kernel. The message is:
+\begin{verbatim}
+Cannot open netlink socket: Invalid value
+\end{verbatim}
+
+\item RTNETLINK is not configured in the kernel. In this case
+one of the following messages may be printed, depending on the command:
+\begin{verbatim}
+Cannot talk to rtnetlink: Connection refused
+Cannot send dump request: Connection refused
+\end{verbatim}
+
+\item The \verb|CONFIG_IP_MULTIPLE_TABLES| option was not selected
+when configuring the kernel. In this case any attempt to use the
+\verb|ip| \verb|rule| command will fail, f.e.
+\begin{verbatim}
+kuznet@kaiser $ ip rule list
+RTNETLINK error: Invalid argument
+dump terminated
+\end{verbatim}
+
+\end{enumerate}
+
+
+\section{{\tt ip link} --- network device configuration}
+\label{IP-LINK}
+
+\paragraph{Object:} A \verb|link| is a network device and the corresponding
+commands display and change the state of devices.
+
+\paragraph{Commands:} \verb|set| and \verb|show| (or \verb|list|).
+
+\subsection{{\tt ip link set} --- change device attributes}
+
+\paragraph{Abbreviations:} \verb|set|, \verb|s|.
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+\item \verb|dev NAME| (default)
+
+--- \verb|NAME| specifies the network device on which to operate.
+
+\item \verb|up| and \verb|down|
+
+--- change the state of the device to \verb|UP| or \verb|DOWN|.
+
+\item \verb|arp on| or \verb|arp off|
+
+--- change the \verb|NOARP| flag on the device.
+
+\begin{NB}
+This operation is {\em not allowed\/} if the device is in state \verb|UP|.
+Though neither the \verb|ip| utility nor the kernel check for this condition.
+You can get unpredictable results changing this flag while the
+device is running.
+\end{NB}
+
+\item \verb|multicast on| or \verb|multicast off|
+
+--- change the \verb|MULTICAST| flag on the device.
+
+\item \verb|dynamic on| or \verb|dynamic off|
+
+--- change the \verb|DYNAMIC| flag on the device.
+
+\item \verb|name NAME|
+
+--- change the name of the device. This operation is not
+recommended if the device is running or has some addresses
+already configured.
+
+\item \verb|txqueuelen NUMBER| or \verb|txqlen NUMBER|
+
+--- change the transmit queue length of the device.
+
+\item \verb|mtu NUMBER|
+
+--- change the MTU of the device.
+
+\item \verb|address LLADDRESS|
+
+--- change the station address of the interface.
+
+\item \verb|broadcast LLADDRESS|, \verb|brd LLADDRESS| or \verb|peer LLADDRESS|
+
+--- change the link layer broadcast address or the peer address when
+the interface is \verb|POINTOPOINT|.
+
+\vskip 1mm
+\begin{NB}
+For most devices (f.e.\ for Ethernet) changing the link layer
+broadcast address will break networking.
+Do not use it, if you do not understand what this operation really does.
+\end{NB}
+
+\item \verb|netns PID|
+
+--- move the device to the network namespace associated with the process PID.
+
+\end{itemize}
+
+\vskip 1mm
+\begin{NB}
+The \verb|PROMISC| and \verb|ALLMULTI| flags are considered
+obsolete and should not be changed administratively, though
+the {\tt ip} utility will allow that.
+\end{NB}
+
+\paragraph{Warning:} If multiple parameter changes are requested,
+\verb|ip| aborts immediately after any of the changes have failed.
+This is the only case when \verb|ip| can move the system to
+an unpredictable state. The solution is to avoid changing
+several parameters with one {\tt ip link set} call.
+
+\paragraph{Examples:}
+\begin{itemize}
+\item \verb|ip link set dummy address 00:00:00:00:00:01|

+\subsection{{\tt ip link show} --- display device attributes}
+\label{IP-LINK-SHOW}
+
+\paragraph{Abbreviations:} \verb|show|, \verb|list|, \verb|lst|, \verb|sh|, \verb|ls|,
+\verb|l|.
+
+\paragraph{Arguments:}
+\begin{itemize}
+\item \verb|dev NAME| (default)
+
+--- \verb|NAME| specifies the network device to show.
+If this argument is omitted all devices are listed.
+
+\item \verb|up|
+
+--- only display running interfaces.
+
+\end{itemize}
+
+
+\paragraph{Output format:}
+
+\begin{verbatim}
+kuznet@alisa:~ $ ip link ls eth0
+3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc cbq qlen 100
+ link/ether 00:a0:cc:66:18:78 brd ff:ff:ff:ff:ff:ff

+ link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff
+kuznet@alisa:~ $
+\end{verbatim}
+
+
+The number before each colon is an {\em interface index\/} or {\em ifindex\/}.
+This number uniquely identifies the interface. This is followed by the {\em interface name\/}
+(\verb|eth0|, \verb|sit0| etc.). The interface name is also
+unique at every given moment. However, the interface may disappear from the
+list (f.e.\ when the corresponding driver module is unloaded) and another
+one with the same name may be created later. Besides that,
+the administrator may change the name of any device with
+\verb|ip| \verb|link| \verb|set| \verb|name|
+to make it more intelligible.
+
+The interface name may have another name or \verb|NONE| appended
+after the \verb|@| sign. This means that this device is bound to some other
+device,
+i.e.\ packets send through it are encapsulated and sent via the ``master''
+device. If the name is \verb|NONE|, the master is unknown.
+
+Then we see the interface {\em mtu\/} (``maximal transfer unit''). This determines
+the maximal size of data which can be sent as a single packet over this interface.
+
+{\em qdisc\/} (``queuing discipline'') shows the queuing algorithm used
+on the interface. Particularly, \verb|noqueue| means that this interface
+does not queue anything and \verb|noop| means that the interface is in blackhole
+mode i.e.\ all packets sent to it are immediately discarded.
+{\em qlen\/} is the default transmit queue length of the device measured
+in packets.
+
+The interface flags are summarized in the angle brackets.
+
+\begin{itemize}
+\item \verb|UP| --- the device is turned on. It is ready to accept
+packets for transmission and it may inject into the kernel packets received
+from other nodes on the network.
+
+\item \verb|LOOPBACK| --- the interface does not communicate with other
+hosts. All packets sent through it will be returned
+and nothing but bounced packets can be received.
+
+\item \verb|BROADCAST| --- the device has the facility to send packets
+to all hosts sharing the same link. A typical example is an Ethernet link.
+
+\item \verb|POINTOPOINT| --- the link has only two ends with one node
+attached to each end. All packets sent to this link will reach the peer
+and all packets received by us came from this single peer.
+
+If neither \verb|LOOPBACK| nor \verb|BROADCAST| nor \verb|POINTOPOINT|
+are set, the interface is assumed to be NMBA (Non-Broadcast Multi-Access).
+This is the most generic type of device and the most complicated one, because
+the host attached to a NBMA link has no means to send to anyone
+without additionally configured information.
+
+\item \verb|MULTICAST| --- is an advisory flag indicating that the interface
+is aware of multicasting i.e.\ sending packets to some subset of neighbouring
+nodes. Broadcasting is a particular case of multicasting, where the multicast
+group consists of all nodes on the link. It is important to emphasize
+that software {\em must not\/} interpret the absence of this flag as the inability
+to use multicasting on this interface. Any \verb|POINTOPOINT| and
+\verb|BROADCAST| link is multicasting by definition, because we have
+direct access to all the neighbours and, hence, to any part of them.
+Certainly, the use of high bandwidth multicast transfers is not recommended
+on broadcast-only links because of high expense, but it is not strictly
+prohibited.
+
+\item \verb|PROMISC| --- the device listens to and feeds to the kernel all
+traffic on the link even if it is not destined for us, not broadcasted
+and not destined for a multicast group of which we are member. Usually
+this mode exists only on broadcast links and is used by bridges and for network
+monitoring.
+
+\item \verb|ALLMULTI| --- the device receives all multicast packets
+wandering on the link. This mode is used by multicast routers.
+
+\item \verb|NOARP| --- this flag is different from the other ones. It has
+no invariant value and its interpretation depends on the network protocols
+involved. As a rule, it indicates that the device needs no address
+resolution and that the software or hardware knows how to deliver packets
+without any help from the protocol stacks.
+
+\item \verb|DYNAMIC| --- is an advisory flag indicating that the interface is
+dynamically created and destroyed.
+
+\item \verb|SLAVE| --- this interface is bonded to some other interfaces
+to share link capacities.
+
+\end{itemize}
+
+\vskip 1mm
+\begin{NB}
+There are other flags but they are either obsolete (\verb|NOTRAILERS|)
+or not implemented (\verb|DEBUG|) or specific to some devices
+(\verb|MASTER|, \verb|AUTOMEDIA| and \verb|PORTSEL|). We do not discuss
+them here.
+\end{NB}
+
+
+The second line contains information on the link layer addresses
+associated with the device. The first word (\verb|ether|, \verb|sit|)
+defines the interface hardware type. This type determines the format and semantics
+of the addresses and is logically part of the address.
+The default format of the station address and the broadcast address
+(or the peer address for pointopoint links) is a
+sequence of hexadecimal bytes separated by colons, but some link
+types may have their natural address format, f.e.\ addresses
+of tunnels over IP are printed as dotted-quad IP addresses.
+
+\vskip 1mm
+\begin{NB}
+ NBMA links have no well-defined broadcast or peer address,
+ however this field may contain useful information, f.e.\
+ about the address of broadcast relay or about the address of the ARP server.
+\end{NB}
+\begin{NB}
+Multicast addresses are not shown by this command, see
+\verb|ip maddr ls| in~Sec.\ref{IP-MADDR} (p.\pageref{IP-MADDR} of this
+document).
+\end{NB}
+
+
+\paragraph{Statistics:} With the \verb|-statistics| option, \verb|ip| also
+prints interface statistics:
+
+\begin{verbatim}
+kuznet@alisa:~ $ ip -s link ls eth0
+3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc cbq qlen 100
+ link/ether 00:a0:cc:66:18:78 brd ff:ff:ff:ff:ff:ff
+ RX: bytes packets errors dropped overrun mcast
+ 2449949362 2786187 0 0 0 0
+ TX: bytes packets errors dropped carrier collsns
+ 178558497 1783945 332 0 332 35172
+kuznet@alisa:~ $
+\end{verbatim}
+\verb|RX:| and \verb|TX:| lines summarize receiver and transmitter
+statistics. They contain:
+\begin{itemize}
+\item \verb|bytes| --- the total number of bytes received or transmitted
+on the interface. This number wraps when the maximal length of the data type
+natural for the architecture is exceeded, so continuous monitoring requires
+a user level daemon snapping it periodically.
+\item \verb|packets| --- the total number of packets received or transmitted
+on the interface.
+\item \verb|errors| --- the total number of receiver or transmitter errors.
+\item \verb|dropped| --- the total number of packets dropped due to lack
+of resources.
+\item \verb|overrun| --- the total number of receiver overruns resulting
+in dropped packets. As a rule, if the interface is overrun, it means
+serious problems in the kernel or that your machine is too slow
+for this interface.
+\item \verb|mcast| --- the total number of received multicast packets. This option
+is only supported by a few devices.
+\item \verb|carrier| --- total number of link media failures f.e.\ because
+of lost carrier.
+\item \verb|collsns| --- the total number of collision events
+on Ethernet-like media. This number may have a different sense on other
+link types.
+\item \verb|compressed| --- the total number of compressed packets. This is
+available only for links using VJ header compression.
+\end{itemize}
+
+
+If the \verb|-s| option is entered twice or more,
+\verb|ip| prints more detailed statistics on receiver
+and transmitter errors.
+
+\begin{verbatim}
+kuznet@alisa:~ $ ip -s -s link ls eth0

+
+\section{{\tt ip address} --- protocol address management}
+
+\paragraph{Abbreviations:} \verb|address|, \verb|addr|, \verb|a|.
+
+\paragraph{Object:} The \verb|address| is a protocol (IP or IPv6) address attached
+to a network device. Each device must have at least one address
+to use the corresponding protocol. It is possible to have several
+different addresses attached to one device. These addresses are not
+discriminated, so that the term {\em alias\/} is not quite appropriate
+for them and we do not use it in this document.
+
+The \verb|ip addr| command displays addresses and their properties,
+adds new addresses and deletes old ones.
+
+\paragraph{Commands:} \verb|add|, \verb|delete|, \verb|flush| and \verb|show|
+(or \verb|list|).
+
+
+\subsection{{\tt ip address add} --- add a new protocol address}
+\label{IP-ADDR-ADD}
+
+\paragraph{Abbreviations:} \verb|add|, \verb|a|.
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+\item \verb|dev NAME|
+
+\noindent--- the name of the device to add the address to.
+
+\item \verb|local ADDRESS| (default)
+
+--- the address of the interface. The format of the address depends
+on the protocol. It is a dotted quad for IP and a sequence of hexadecimal halfwords
+separated by colons for IPv6. The \verb|ADDRESS| may be followed by
+a slash and a decimal number which encodes the network prefix length.
+
+
+\item \verb|peer ADDRESS|
+
+--- the address of the remote endpoint for pointopoint interfaces.
+Again, the \verb|ADDRESS| may be followed by a slash and a decimal number,
+encoding the network prefix length. If a peer address is specified,
+the local address {\em cannot\/} have a prefix length. The network prefix is associated
+with the peer rather than with the local address.
+
+
+\item \verb|broadcast ADDRESS|
+
+--- the broadcast address on the interface.
+
+It is possible to use the special symbols \verb|'+'| and \verb|'-'|
+instead of the broadcast address. In this case, the broadcast address
+is derived by setting/resetting the host bits of the interface prefix.
+
+\vskip 1mm
+\begin{NB}
+Unlike \verb|ifconfig|, the \verb|ip| utility {\em does not\/} set any broadcast
+address unless explicitly requested.
+\end{NB}
+
+
+\item \verb|label NAME|
+
+--- Each address may be tagged with a label string.
+In order to preserve compatibility with Linux-2.0 net aliases,
+this string must coincide with the name of the device or must be prefixed
+with the device name followed by colon.
+
+
+\item \verb|scope SCOPE_VALUE|
+
+--- the scope of the area where this address is valid.
+The available scopes are listed in file \verb|/etc/iproute2/rt_scopes|.
+Predefined scope values are:
+
+ \begin{itemize}
+ \item \verb|global| --- the address is globally valid.
+ \item \verb|site| --- (IPv6 only) the address is site local,
+ i.e.\ it is valid inside this site.
+ \item \verb|link| --- the address is link local, i.e.\
+ it is valid only on this device.
+ \item \verb|host| --- the address is valid only inside this host.
+ \end{itemize}
+
+Appendix~\ref{ADDR-SEL} (p.\pageref{ADDR-SEL} of this document)
+contains more details on address scopes.
+
+\end{itemize}
+
+\paragraph{Examples:}
+\begin{itemize}
+\item \verb|ip addr add 127.0.0.1/8 dev lo brd + scope host|
+
+--- add the usual loopback address to the loopback device.
+
+\item \verb|ip addr add 10.0.0.1/24 brd + dev eth0 label eth0:Alias|
+
+--- add the address 10.0.0.1 with prefix length 24 (i.e.\ netmask
+\verb|255.255.255.0|), standard broadcast and label \verb|eth0:Alias|
+to the interface \verb|eth0|.
+\end{itemize}
+
+
+\subsection{{\tt ip address delete} --- delete a protocol address}
+
+\paragraph{Abbreviations:} \verb|delete|, \verb|del|, \verb|d|.
+
+\paragraph{Arguments:} coincide with the arguments of \verb|ip addr add|.
+The device name is a required argument. The rest are optional.
+If no arguments are given, the first address is deleted.
+
+\paragraph{Examples:}
+\begin{itemize}
+\item \verb|ip addr del 127.0.0.1/8 dev lo|
+
+--- deletes the loopback address from the loopback device.
+It would be best not to repeat this experiment.
+
+\item Disable IP on the interface \verb|eth0|:
+\begin{verbatim}
+ while ip -f inet addr del dev eth0; do
+ : nothing
+ done
+\end{verbatim}
+Another method to disable IP on an interface using {\tt ip addr flush}
+may be found in sec.\ref{IP-ADDR-FLUSH}, p.\pageref{IP-ADDR-FLUSH}.
+
+\end{itemize}
+
+
+\subsection{{\tt ip address show} --- display protocol addresses}
+
+\paragraph{Abbreviations:} \verb|show|, \verb|list|, \verb|lst|, \verb|sh|, \verb|ls|,
+\verb|l|.
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+\item \verb|dev NAME| (default)
+
+--- the name of the device.
+
+\item \verb|scope SCOPE_VAL|
+
+--- only list addresses with this scope.
+
+\item \verb|to PREFIX|
+
+--- only list addresses matching this prefix.
+
+\item \verb|label PATTERN|
+
+--- only list addresses with labels matching the \verb|PATTERN|.
+\verb|PATTERN| is a usual shell style pattern.
+
+
+\item \verb|dynamic| and \verb|permanent|
+
+--- (IPv6 only) only list addresses installed due to stateless
+address configuration or only list permanent (not dynamic) addresses.
+
+\item \verb|tentative|
+
+--- (IPv6 only) only list addresses which did not pass duplicate
+address detection.
+
+\item \verb|deprecated|
+
+--- (IPv6 only) only list deprecated addresses.
+
+
+\item \verb|primary| and \verb|secondary|
+
+--- only list primary (or secondary) addresses.
+
+\end{itemize}
+
+
+\paragraph{Output format:}
+
+\begin{verbatim}
+kuznet@alisa:~ $ ip addr ls eth0
+3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc cbq qlen 100
+ link/ether 00:a0:cc:66:18:78 brd ff:ff:ff:ff:ff:ff

+ valid_lft forever preferred_lft 604746sec
+ inet6 fe80::2a0:ccff:fe66:1878/10 scope link
+kuznet@alisa:~ $
+\end{verbatim}
+
+The first two lines coincide with the output of \verb|ip link ls|.
+It is natural to interpret link layer addresses
+as addresses of the protocol family \verb|AF_PACKET|.
+
+Then the list of IP and IPv6 addresses follows, accompanied by
+additional address attributes: scope value (see Sec.\ref{IP-ADDR-ADD},
+p.\pageref{IP-ADDR-ADD} above), flags and the address label.
+
+Address flags are set by the kernel and cannot be changed
+administratively. Currently, the following flags are defined:
+
+\begin{enumerate}
+\item \verb|secondary|
+
+--- the address is not used when selecting the default source address
+of outgoing packets (Cf.\ Appendix~\ref{ADDR-SEL}, p.\pageref{ADDR-SEL}.).
+An IP address becomes secondary if another address with the same
+prefix bits already exists. The first address is primary.
+It is the leader of the group of all secondary addresses. When the leader
+is deleted, all secondaries are purged too.
+There is a tweak in \verb|/proc/sys/net/ipv4/conf/<dev>/promote_secondaries|
+which activate secondaries promotion when a primary is deleted.
+To permanently enable this feature on all devices add
+\verb|net.ipv4.conf.all.promote_secondaries=1| to \verb|/etc/sysctl.conf|.
+This tweak is available in linux 2.6.15 and later.
+
+
+\item \verb|dynamic|
+
+--- the address was created due to stateless autoconfiguration~\cite{RFC-ADDRCONF}.
+In this case the output also contains information on times, when
+the address is still valid. After \verb|preferred_lft| expires the address is
+moved to the deprecated state. After \verb|valid_lft| expires the address
+is finally invalidated.
+
+\item \verb|deprecated|
+
+--- the address is deprecated, i.e.\ it is still valid, but cannot
+be used by newly created connections.
+
+\item \verb|tentative|
+
+--- the address is not used because duplicate address detection~\cite{RFC-ADDRCONF}
+is still not complete or failed.
+
+\end{enumerate}
+
+
+\subsection{{\tt ip address flush} --- flush protocol addresses}
+\label{IP-ADDR-FLUSH}
+
+\paragraph{Abbreviations:} \verb|flush|, \verb|f|.
+
+\paragraph{Description:}This command flushes the protocol addresses
+selected by some criteria.
+
+\paragraph{Arguments:} This command has the same arguments as \verb|show|.
+The difference is that it does not run when no arguments are given.
+
+\paragraph{Warning:} This command (and other \verb|flush| commands
+described below) is pretty dangerous. If you make a mistake, it will
+not forgive it, but will cruelly purge all the addresses.
+
+\paragraph{Statistics:} With the \verb|-statistics| option, the command
+becomes verbose. It prints out the number of deleted addresses and the number
+of rounds made to flush the address list. If this option is given
+twice, \verb|ip addr flush| also dumps all the deleted addresses
+in the format described in the previous subsection.
+
+\paragraph{Example:} Delete all the addresses from the private network
+10.0.0.0/8:
+\begin{verbatim}
+netadm@amber:~ # ip -s -s a f to 10/8
+2: dummy inet 10.7.7.7/16 brd 10.7.255.255 scope global dummy
+3: eth0 inet 10.10.7.7/16 brd 10.10.255.255 scope global eth0
+4: eth1 inet 10.8.7.7/16 brd 10.8.255.255 scope global eth1
+
+*** Round 1, deleting 3 addresses ***
+*** Flush is complete after 1 round ***
+netadm@amber:~ #
+\end{verbatim}
+Another instructive example is disabling IP on all the Ethernets:
+\begin{verbatim}
+netadm@amber:~ # ip -4 addr flush label "eth*"
+\end{verbatim}
+And the last example shows how to flush all the IPv6 addresses
+acquired by the host from stateless address autoconfiguration
+after you enabled forwarding or disabled autoconfiguration.
+\begin{verbatim}
+netadm@amber:~ # ip -6 addr flush dynamic
+\end{verbatim}
+
+
+
+\section{{\tt ip neighbour} --- neighbour/arp tables management}
+
+\paragraph{Abbreviations:} \verb|neighbour|, \verb|neighbor|, \verb|neigh|,
+\verb|n|.
+
+\paragraph{Object:} \verb|neighbour| objects establish bindings between protocol
+addresses and link layer addresses for hosts sharing the same link.
+Neighbour entries are organized into tables. The IPv4 neighbour table
+is known by another name --- the ARP table.
+
+The corresponding commands display neighbour bindings
+and their properties, add new neighbour entries and delete old ones.
+
+\paragraph{Commands:} \verb|add|, \verb|change|, \verb|replace|,
+\verb|delete|, \verb|flush| and \verb|show| (or \verb|list|).
+
+\paragraph{See also:} Appendix~\ref{PROXY-NEIGH}, p.\pageref{PROXY-NEIGH}
+describes how to manage proxy ARP/NDISC with the \verb|ip| utility.
+
+
+\subsection{{\tt ip neighbour add} --- add a new neighbour entry\\
+ {\tt ip neighbour change} --- change an existing entry\\
+ {\tt ip neighbour replace} --- add a new entry or change an existing one}
+
+\paragraph{Abbreviations:} \verb|add|, \verb|a|; \verb|change|, \verb|chg|;
+\verb|replace|, \verb|repl|.
+
+\paragraph{Description:} These commands create new neighbour records
+or update existing ones.
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+\item \verb|to ADDRESS| (default)
+
+--- the protocol address of the neighbour. It is either an IPv4 or IPv6 address.
+
+\item \verb|dev NAME|
+
+--- the interface to which this neighbour is attached.
+
+
+\item \verb|lladdr LLADDRESS|
+
+--- the link layer address of the neighbour. \verb|LLADDRESS| can also be
+\verb|null|.
+
+\item \verb|nud NUD_STATE|
+
+--- the state of the neighbour entry. \verb|nud| is an abbreviation for ``Neighbour
+Unreachability Detection''. The state can take one of the following values:
+
+\begin{enumerate}
+\item \verb|permanent| --- the neighbour entry is valid forever and can be only be removed
+administratively.
+\item \verb|noarp| --- the neighbour entry is valid. No attempts to validate
+this entry will be made but it can be removed when its lifetime expires.
+\item \verb|reachable| --- the neighbour entry is valid until the reachability
+timeout expires.
+\item \verb|stale| --- the neighbour entry is valid but suspicious.
+This option to \verb|ip neigh| does not change the neighbour state if
+it was valid and the address is not changed by this command.
+\end{enumerate}
+
+\end{itemize}
+
+\paragraph{Examples:}
+\begin{itemize}
+\item \verb|ip neigh add 10.0.0.3 lladdr 0:0:0:0:0:1 dev eth0 nud perm|
+
+--- add a permanent ARP entry for the neighbour 10.0.0.3 on the device \verb|eth0|.
+
+\item \verb|ip neigh chg 10.0.0.3 dev eth0 nud reachable|
+
+--- change its state to \verb|reachable|.
+\end{itemize}
+
+
+\subsection{{\tt ip neighbour delete} --- delete a neighbour entry}
+
+\paragraph{Abbreviations:} \verb|delete|, \verb|del|, \verb|d|.
+
+\paragraph{Description:} This command invalidates a neighbour entry.
+
+\paragraph{Arguments:} The arguments are the same as with \verb|ip neigh add|,
+except that \verb|lladdr| and \verb|nud| are ignored.
+
+
+\paragraph{Example:}
+\begin{itemize}
+\item \verb|ip neigh del 10.0.0.3 dev eth0|
+
+--- invalidate an ARP entry for the neighbour 10.0.0.3 on the device \verb|eth0|.
+
+\end{itemize}
+
+\begin{NB}
+ The deleted neighbour entry will not disappear from the tables
+ immediately. If it is in use it cannot be deleted until the last
+ client releases it. Otherwise it will be destroyed during
+ the next garbage collection.
+\end{NB}
+
+
+\paragraph{Warning:} Attempts to delete or manually change
+a \verb|noarp| entry created by the kernel may result in unpredictable behaviour.
+Particularly, the kernel may try to resolve this address even
+on a \verb|NOARP| interface or if the address is multicast or broadcast.
+
+
+\subsection{{\tt ip neighbour show} --- list neighbour entries}
+
+\paragraph{Abbreviations:} \verb|show|, \verb|list|, \verb|sh|, \verb|ls|.
+
+\paragraph{Description:}This commands displays neighbour tables.
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+
+\item \verb|to ADDRESS| (default)
+
+--- the prefix selecting the neighbours to list.
+
+\item \verb|dev NAME|
+
+--- only list the neighbours attached to this device.
+
+\item \verb|unused|
+
+--- only list neighbours which are not currently in use.
+
+\item \verb|nud NUD_STATE|
+
+--- only list neighbour entries in this state. \verb|NUD_STATE| takes
+values listed below or the special value \verb|all| which means all states.
+This option may occur more than once. If this option is absent, \verb|ip|
+lists all entries except for \verb|none| and \verb|noarp|.

+state machine can be found in~\cite{RFC-NDISC}. Here is the full list
+of the states with short descriptions:
+
+\begin{enumerate}
+\item\verb|none| --- the state of the neighbour is void.
+\item\verb|incomplete| --- the neighbour is in the process of resolution.
+\item\verb|reachable| --- the neighbour is valid and apparently reachable.
+\item\verb|stale| --- the neighbour is valid, but is probably already
+unreachable, so the kernel will try to check it at the first transmission.
+\item\verb|delay| --- a packet has been sent to the stale neighbour and the kernel is waiting
+for confirmation.
+\item\verb|probe| --- the delay timer expired but no confirmation was received.
+The kernel has started to probe the neighbour with ARP/NDISC messages.
+\item\verb|failed| --- resolution has failed.
+\item\verb|noarp| --- the neighbour is valid. No attempts to check the entry
+will be made.
+\item\verb|permanent| --- it is a \verb|noarp| entry, but only the administrator
+may remove the entry from the neighbour table.
+\end{enumerate}
+
+The link layer address is valid in all states except for \verb|none|,
+\verb|failed| and \verb|incomplete|.
+
+IPv6 neighbours can be marked with the additional flag \verb|router|
+which means that the neighbour introduced itself as an IPv6 router~\cite{RFC-NDISC}.
+
+\paragraph{Statistics:} The \verb|-statistics| option displays some usage
+statistics, f.e.\
+
+\begin{verbatim}
+kuznet@alisa:~ $ ip -s n ls 193.233.7.254
+193.233.7.254 dev eth0 lladdr 00:00:0c:76:3f:85 ref 5 used 12/13/20 \
+ nud reachable
+kuznet@alisa:~ $
+\end{verbatim}
+
+Here \verb|ref| is the number of users of this entry
+and \verb|used| is a triplet of time intervals in seconds
+separated by slashes. In this case they show that:
+
+\begin{enumerate}
+\item the entry was used 12 seconds ago.
+\item the entry was confirmed 13 seconds ago.
+\item the entry was updated 20 seconds ago.
+\end{enumerate}
+
+\subsection{{\tt ip neighbour flush} --- flush neighbour entries}
+
+\paragraph{Abbreviations:} \verb|flush|, \verb|f|.
+
+\paragraph{Description:}This command flushes neighbour tables, selecting
+entries to flush by some criteria.
+
+\paragraph{Arguments:} This command has the same arguments as \verb|show|.
+The differences are that it does not run when no arguments are given,
+and that the default neighbour states to be flushed do not include
+\verb|permanent| and \verb|noarp|.
+
+
+\paragraph{Statistics:} With the \verb|-statistics| option, the command
+becomes verbose. It prints out the number of deleted neighbours and the number
+of rounds made to flush the neighbour table. If the option is given
+twice, \verb|ip neigh flush| also dumps all the deleted neighbours
+in the format described in the previous subsection.
+
+\paragraph{Example:}
+\begin{verbatim}
+netadm@alisa:~ # ip -s -s n f 193.233.7.254
+193.233.7.254 dev eth0 lladdr 00:00:0c:76:3f:85 ref 5 used 12/13/20 \
+ nud reachable
+
+*** Round 1, deleting 1 entries ***
+*** Flush is complete after 1 round ***
+netadm@alisa:~ #
+\end{verbatim}

+\section{{\tt ip route} --- routing table management}
+\label{IP-ROUTE}
+
+\paragraph{Abbreviations:} \verb|route|, \verb|ro|, \verb|r|.
+
+\paragraph{Object:} \verb|route| entries in the kernel routing tables keep
+information about paths to other networked nodes.
+
+Each route entry has a {\em key\/} consisting of a {\em prefix\/}
+(i.e.\ a pair containing a network address and the length of its mask) and,
+optionally, the TOS value. An IP packet matches the route if the highest
+bits of its destination address are equal to the route prefix at least
+up to the prefix length and if the TOS of the route is zero or equal to
+the TOS of the packet.
+
+If several routes match the packet, the following pruning rules
+are used to select the best one (see~\cite{RFC1812}):
+\begin{enumerate}
+\item The longest matching prefix is selected. All shorter ones
+are dropped.
+
+\item If the TOS of some route with the longest prefix is equal to the TOS
+of the packet, the routes with different TOS are dropped.
+
+If no exact TOS match was found and routes with TOS=0 exist,
+the rest of routes are pruned.
+
+Otherwise, the route lookup fails.
+
+\item If several routes remain after the previous steps, then
+the routes with the best preference values are selected.
+
+\item If we still have several routes, then the {\em first\/} of them
+is selected.
+
+\begin{NB}
+ Note the ambiguity of the last step. Unfortunately, Linux
+ historically allows such a bizarre situation. The sense of the
+word ``first'' depends on the order of route additions and it is practically
+impossible to maintain a bundle of such routes in this order.
+\end{NB}
+
+For simplicity we will limit ourselves to the case where such a situation
+is impossible and routes are uniquely identified by the triplet
+\{prefix, tos, preference\}. Actually, it is impossible to create
+non-unique routes with \verb|ip| commands described in this section.
+
+One useful exception to this rule is the default route on non-forwarding
+hosts. It is ``officially'' allowed to have several fallback routes
+when several routers are present on directly connected networks.
+In this case, Linux-2.2 makes ``dead gateway detection''~\cite{RFC1122}
+controlled by neighbour unreachability detection and by advice
+from transport protocols to select a working router, so the order
+of the routes is not essential. However, in this case,
+fiddling with default routes manually is not recommended. Use the Router Discovery
+protocol (see Appendix~\ref{EXAMPLE-SETUP}, p.\pageref{EXAMPLE-SETUP})
+instead. Actually, Linux-2.2 IPv6 does not give user level applications
+any access to default routes.
+\end{enumerate}
+
+Certainly, the steps above are not performed exactly
+in this sequence. Instead, the routing table in the kernel is kept
+in some data structure to achieve the final result
+with minimal cost. However, not depending on a particular
+routing algorithm implemented in the kernel, we can summarize
+the statements above as: a route is identified by the triplet
+\{prefix, tos, preference\}. This {\em key\/} lets us locate
+the route in the routing table.
+
+\paragraph{Route attributes:} Each route key refers to a routing
+information record containing
+the data required to deliver IP packets (f.e.\ output device and
+next hop router) and some optional attributes (f.e. the path MTU or
+the preferred source address when communicating with this destination).
+These attributes are described in the following subsection.
+
+\paragraph{Route types:} \label{IP-ROUTE-TYPES}
+It is important that the set
+of required and optional attributes depend on the route {\em type\/}.
+The most important route type
+is \verb|unicast|. It describes real paths to other hosts.
+As a rule, common routing tables contain only such routes. However,
+there are other types of routes with different semantics. The
+full list of types understood by Linux-2.2 is:
+\begin{itemize}
+\item \verb|unicast| --- the route entry describes real paths to the
+destinations covered by the route prefix.
+\item \verb|unreachable| --- these destinations are unreachable. Packets
+are discarded and the ICMP message {\em host unreachable\/} is generated.
+The local senders get an \verb|EHOSTUNREACH| error.
+\item \verb|blackhole| --- these destinations are unreachable. Packets
+are discarded silently. The local senders get an \verb|EINVAL| error.
+\item \verb|prohibit| --- these destinations are unreachable. Packets
+are discarded and the ICMP message {\em communication administratively
+prohibited\/} is generated. The local senders get an \verb|EACCES| error.
+\item \verb|local| --- the destinations are assigned to this
+host. The packets are looped back and delivered locally.
+\item \verb|broadcast| --- the destinations are broadcast addresses.
+The packets are sent as link broadcasts.
+\item \verb|throw| --- a special control route used together with policy
+rules (see sec.\ref{IP-RULE}, p.\pageref{IP-RULE}). If such a route is selected, lookup
+in this table is terminated pretending that no route was found.
+Without policy routing it is equivalent to the absence of the route in the routing
+table. The packets are dropped and the ICMP message {\em net unreachable\/}
+is generated. The local senders get an \verb|ENETUNREACH| error.
+\item \verb|nat| --- a special NAT route. Destinations covered by the prefix
+are considered to be dummy (or external) addresses which require translation
+to real (or internal) ones before forwarding. The addresses to translate to
+are selected with the attribute \verb|via|. More about NAT is
+in Appendix~\ref{ROUTE-NAT}, p.\pageref{ROUTE-NAT}.
+\item \verb|anycast| --- ({\em not implemented\/}) the destinations are
+{\em anycast\/} addresses assigned to this host. They are mainly equivalent
+to \verb|local| with one difference: such addresses are invalid when used
+as the source address of any packet.
+\item \verb|multicast| --- a special type used for multicast routing.
+It is not present in normal routing tables.
+\end{itemize}
+
+\paragraph{Route tables:} Linux-2.2 can pack routes into several routing
+tables identified by a number in the range from 1 to 255 or by
+name from the file \verb|/etc/iproute2/rt_tables|. By default all normal
+routes are inserted into the \verb|main| table (ID 254) and the kernel only uses
+this table when calculating routes.
+
+Actually, one other table always exists, which is invisible but
+even more important. It is the \verb|local| table (ID 255). This table
+consists of routes for local and broadcast addresses. The kernel maintains
+this table automatically and the administrator usually need not modify it
+or even look at it.
+
+The multiple routing tables enter the game when {\em policy routing\/}
+is used. See sec.\ref{IP-RULE}, p.\pageref{IP-RULE}.
+In this case, the table identifier effectively becomes
+one more parameter, which should be added to the triplet
+\{prefix, tos, preference\} to uniquely identify the route.
+
+
+\subsection{{\tt ip route add} --- add a new route\\
+ {\tt ip route change} --- change a route\\
+ {\tt ip route replace} --- change a route or add a new one}
+\label{IP-ROUTE-ADD}
+
+\paragraph{Abbreviations:} \verb|add|, \verb|a|; \verb|change|, \verb|chg|;
+ \verb|replace|, \verb|repl|.
+
+
+\paragraph{Arguments:}
+\begin{itemize}
+\item \verb|to PREFIX| or \verb|to TYPE PREFIX| (default)
+
+--- the destination prefix of the route. If \verb|TYPE| is omitted,
+\verb|ip| assumes type \verb|unicast|. Other values of \verb|TYPE|
+are listed above. \verb|PREFIX| is an IP or IPv6 address optionally followed
+by a slash and the prefix length. If the length of the prefix is missing,
+\verb|ip| assumes a full-length host route. There is also a special
+\verb|PREFIX| --- \verb|default| --- which is equivalent to IP \verb|0/0| or
+to IPv6 \verb|::/0|.
+
+\item \verb|tos TOS| or \verb|dsfield TOS|
+
+--- the Type Of Service (TOS) key. This key has no associated mask and
+the longest match is understood as: First, compare the TOS
+of the route and of the packet. If they are not equal, then the packet
+may still match a route with a zero TOS. \verb|TOS| is either an 8 bit hexadecimal
+number or an identifier from {\tt /etc/iproute2/rt\_dsfield}.
+
+
+\item \verb|metric NUMBER| or \verb|preference NUMBER|
+
+--- the preference value of the route. \verb|NUMBER| is an arbitrary 32bit number.
+
+\item \verb|table TABLEID|
+
+--- the table to add this route to.
+\verb|TABLEID| may be a number or a string from the file
+\verb|/etc/iproute2/rt_tables|. If this parameter is omitted,
+\verb|ip| assumes the \verb|main| table, with the exception of
+\verb|local|, \verb|broadcast| and \verb|nat| routes, which are
+put into the \verb|local| table by default.
+
+\item \verb|dev NAME|
+
+--- the output device name.
+
+\item \verb|via ADDRESS|
+
+--- the address of the nexthop router. Actually, the sense of this field depends
+on the route type. For normal \verb|unicast| routes it is either the true nexthop
+router or, if it is a direct route installed in BSD compatibility mode,
+it can be a local address of the interface.
+For NAT routes it is the first address of the block of translated IP destinations.
+
+\item \verb|src ADDRESS|
+
+--- the source address to prefer when sending to the destinations
+covered by the route prefix.
+
+\item \verb|realm REALMID|
+
+--- the realm to which this route is assigned.
+\verb|REALMID| may be a number or a string from the file
+\verb|/etc/iproute2/rt_realms|. Sec.\ref{RT-REALMS} (p.\pageref{RT-REALMS})
+contains more information on realms.
+
+\item \verb|mtu MTU| or \verb|mtu lock MTU|
+
+--- the MTU along the path to the destination. If the modifier \verb|lock| is
+not used, the MTU may be updated by the kernel due to Path MTU Discovery.
+If the modifier \verb|lock| is used, no path MTU discovery will be tried,
+all packets will be sent without the DF bit in IPv4 case
+or fragmented to MTU for IPv6.
+
+\item \verb|window NUMBER|
+
+--- the maximal window for TCP to advertise to these destinations,
+measured in bytes. It limits maximal data bursts that our TCP
+peers are allowed to send to us.
+
+\item \verb|rtt NUMBER|
+
+--- the initial RTT (``Round Trip Time'') estimate.
+
+
+\item \verb|rttvar NUMBER|
+
+--- \threeonly the initial RTT variance estimate.
+
+
+\item \verb|ssthresh NUMBER|
+
+--- \threeonly an estimate for the initial slow start threshold.
+
+
+\item \verb|cwnd NUMBER|
+
+--- \threeonly the clamp for congestion window. It is ignored if the \verb|lock|
+ flag is not used.
+
+
+\item \verb|advmss NUMBER|
+
+--- \threeonly the MSS (``Maximal Segment Size'') to advertise to these
+ destinations when establishing TCP connections. If it is not given,
+ Linux uses a default value calculated from the first hop device MTU.
+
+\begin{NB}
+ If the path to these destination is asymmetric, this guess may be wrong.
+\end{NB}
+
+\item \verb|reordering NUMBER|
+
+--- \threeonly Maximal reordering on the path to this destination.
+ If it is not given, Linux uses the value selected with \verb|sysctl|
+ variable \verb|net/ipv4/tcp_reordering|.
+
+\item \verb|hoplimit NUMBER|
+
+--- [2.5.74+ only] Maximum number of hops on the path to this destination.
+ The default is the value selected with the \verb|sysctl| variable
+ \verb|net/ipv4/ip_default_ttl|.
+
+\item \verb|initcwnd NUMBER|
+--- [2.5.70+ only] Initial congestion window size for connections to
+ this destination. Actual window size is this value multiplied by the
+ MSS (``Maximal Segment Size'') for same connection. The default is
+ zero, meaning to use the values specified in~\cite{RFC2414}.
+
++\item \verb|initrwnd NUMBER|
+
++--- [2.6.33+ only] Initial receive window size for connections to
++ this destination. The actual window size is this value multiplied
++ by the MSS (''Maximal Segment Size'') of the connection. The default
++ value is zero, meaning to use Slow Start value.
+
+\item \verb|nexthop NEXTHOP|
+
+--- the nexthop of a multipath route. \verb|NEXTHOP| is a complex value
+with its own syntax similar to the top level argument lists:
+\begin{itemize}
+\item \verb|via ADDRESS| is the nexthop router.
+\item \verb|dev NAME| is the output device.
+\item \verb|weight NUMBER| is a weight for this element of a multipath
+route reflecting its relative bandwidth or quality.
+\end{itemize}
+
+\item \verb|scope SCOPE_VAL|
+
+--- the scope of the destinations covered by the route prefix.
+\verb|SCOPE_VAL| may be a number or a string from the file
+\verb|/etc/iproute2/rt_scopes|.
+If this parameter is omitted,
+\verb|ip| assumes scope \verb|global| for all gatewayed \verb|unicast|
+routes, scope \verb|link| for direct \verb|unicast| and \verb|broadcast| routes
+and scope \verb|host| for \verb|local| routes.
+
+\item \verb|protocol RTPROTO|
+
+--- the routing protocol identifier of this route.
+\verb|RTPROTO| may be a number or a string from the file
+\verb|/etc/iproute2/rt_protos|. If the routing protocol ID is
+not given, \verb|ip| assumes protocol \verb|boot| (i.e.\
+it assumes the route was added by someone who doesn't
+understand what they are doing). Several protocol values have a fixed interpretation.
+Namely:
+\begin{itemize}
+\item \verb|redirect| --- the route was installed due to an ICMP redirect.
+\item \verb|kernel| --- the route was installed by the kernel during
+autoconfiguration.
+\item \verb|boot| --- the route was installed during the bootup sequence.
+If a routing daemon starts, it will purge all of them.
+\item \verb|static| --- the route was installed by the administrator
+to override dynamic routing. Routing daemon will respect them
+and, probably, even advertise them to its peers.
+\item \verb|ra| --- the route was installed by Router Discovery protocol.
+\end{itemize}
+The rest of the values are not reserved and the administrator is free
+to assign (or not to assign) protocol tags. At least, routing
+daemons should take care of setting some unique protocol values,
+f.e.\ as they are assigned in \verb|rtnetlink.h| or in \verb|rt_protos|
+database.
+
+
+\item \verb|onlink|
+
+--- pretend that the nexthop is directly attached to this link,
+even if it does not match any interface prefix. One application of this
+option may be found in~\cite{IP-TUNNELS}.
+
+\item \verb|pref PREF|
+
+--- the IPv6 route preference.
+\verb|PREF| PREF is a string specifying the route preference as defined in
+RFC4191 for Router Discovery messages. Namely:
+\begin{itemize}
+\item \verb|low| --- the route has a lowest priority.
+\item \verb|medium| --- the route has a default priority.
+\item \verb|high| --- the route has a highest priority.
+\end{itemize}
+
+\end{itemize}
+
+
+\begin{NB}
+ Actually there are more commands: \verb|prepend| does the same
+ thing as classic \verb|route add|, i.e.\ adds a route, even if another
+ route to the same destination exists. Its opposite case is \verb|append|,
+ which adds the route to the end of the list. Avoid these
+ features.
+\end{NB}
+\begin{NB}
+ More sad news, IPv6 only understands the \verb|append| command correctly.
+ All the others are translated into \verb|append| commands. Certainly,
+ this will change in the future.
+\end{NB}
+
+\paragraph{Examples:}
+\begin{itemize}
+\item add a plain route to network 10.0.0/24 via gateway 193.233.7.65
+\begin{verbatim}
+ ip route add 10.0.0/24 via 193.233.7.65
+\end{verbatim}
+\item change it to a direct route via the \verb|dummy| device
+\begin{verbatim}
+ ip ro chg 10.0.0/24 dev dummy
+\end{verbatim}
+\item add a default multipath route splitting the load between \verb|ppp0|
+and \verb|ppp1|
+\begin{verbatim}
+ ip route add default scope global nexthop dev ppp0 \
+ nexthop dev ppp1
+\end{verbatim}
+Note the scope value. It is not necessary but it informs the kernel
+that this route is gatewayed rather than direct. Actually, if you
+know the addresses of remote endpoints it would be better to use the
+\verb|via| parameter.
+\item announce that the address 192.203.80.144 is not a real one, but
+should be translated to 193.233.7.83 before forwarding
+\begin{verbatim}
+ ip route add nat 192.203.80.144 via 193.233.7.83
+\end{verbatim}
+Backward translation is setup with policy rules described
+in the following section (sec.\ref{IP-RULE}, p.\pageref{IP-RULE}).
+\end{itemize}
+
+\subsection{{\tt ip route delete} --- delete a route}
+
+\paragraph{Abbreviations:} \verb|delete|, \verb|del|, \verb|d|.
+
+\paragraph{Arguments:} \verb|ip route del| has the same arguments as
+\verb|ip route add|, but their semantics are a bit different.
+
+Key values (\verb|to|, \verb|tos|, \verb|preference| and \verb|table|)
+select the route to delete. If optional attributes are present, \verb|ip|
+verifies that they coincide with the attributes of the route to delete.
+If no route with the given key and attributes was found, \verb|ip route del|
+fails.
+\begin{NB}
+Linux-2.0 had the option to delete a route selected only by prefix address,
+ignoring its length (i.e.\ netmask). This option no longer exists
+because it was ambiguous. However, look at {\tt ip route flush}
+(sec.\ref{IP-ROUTE-FLUSH}, p.\pageref{IP-ROUTE-FLUSH}) which
+provides similar and even richer functionality.
+\end{NB}
+
+\paragraph{Example:}
+\begin{itemize}
+\item delete the multipath route created by the command in previous subsection
+\begin{verbatim}
+ ip route del default scope global nexthop dev ppp0 \
+ nexthop dev ppp1
+\end{verbatim}
+\end{itemize}
+
+
+
+\subsection{{\tt ip route show} --- list routes}
+
+\paragraph{Abbreviations:} \verb|show|, \verb|list|, \verb|sh|, \verb|ls|, \verb|l|.
+
+\paragraph{Description:} the command displays the contents of the routing tables
+or the route(s) selected by some criteria.
+
+
+\paragraph{Arguments:}
+\begin{itemize}
+\item \verb|to SELECTOR| (default)
+
+--- only select routes from the given range of destinations. \verb|SELECTOR|
+consists of an optional modifier (\verb|root|, \verb|match| or \verb|exact|)
+and a prefix. \verb|root PREFIX| selects routes with prefixes not shorter
+than \verb|PREFIX|. F.e.\ \verb|root 0/0| selects the entire routing table.
+\verb|match PREFIX| selects routes with prefixes not longer than
+\verb|PREFIX|. F.e.\ \verb|match 10.0/16| selects \verb|10.0/16|,
+\verb|10/8| and \verb|0/0|, but it does not select \verb|10.1/16| and
+\verb|10.0.0/24|. And \verb|exact PREFIX| (or just \verb|PREFIX|)
+selects routes with this exact prefix. If neither of these options
+are present, \verb|ip| assumes \verb|root 0/0| i.e.\ it lists the entire table.
+
+
+\item \verb|tos TOS| or \verb|dsfield TOS|
+
+ --- only select routes with the given TOS.
+
+
+\item \verb|table TABLEID|
+
+ --- show the routes from this table(s). The default setting is to show
+\verb|table| \verb|main|. \verb|TABLEID| may either be the ID of a real table
+or one of the special values:
+ \begin{itemize}
+ \item \verb|all| --- list all of the tables.
+ \item \verb|cache| --- dump the routing cache.
+ \end{itemize}
+\begin{NB}
+ IPv6 has a single table. However, splitting it into \verb|main|, \verb|local|
+ and \verb|cache| is emulated by the \verb|ip| utility.
+\end{NB}
+
+\item \verb|cloned| or \verb|cached|
+
+--- list cloned routes i.e.\ routes which were dynamically forked from
+other routes because some route attribute (f.e.\ MTU) was updated.
+Actually, it is equivalent to \verb|table cache|.
+
+\item \verb|from SELECTOR|
+
+--- the same syntax as for \verb|to|, but it binds the source address range
+rather than destinations. Note that the \verb|from| option only works with
+cloned routes.
+
+\item \verb|protocol RTPROTO|
+
+--- only list routes of this protocol.
+
+
+\item \verb|scope SCOPE_VAL|
+
+--- only list routes with this scope.
+
+\item \verb|type TYPE|
+
+--- only list routes of this type.
+
+\item \verb|dev NAME|
+
+--- only list routes going via this device.
+
+\item \verb|via PREFIX|
+
+--- only list routes going via the nexthop routers selected by \verb|PREFIX|.
+
+\item \verb|src PREFIX|
+
+--- only list routes with preferred source addresses selected
+by \verb|PREFIX|.
+
+\item \verb|realm REALMID| or \verb|realms FROMREALM/TOREALM|
+
+--- only list routes with these realms.
+
+\end{itemize}
+
+\paragraph{Examples:} Let us count routes of protocol \verb|gated/bgp|
+on a router:
+\begin{verbatim}
+kuznet@amber:~ $ ip ro ls proto gated/bgp | wc
+ 1413 9891 79010
+kuznet@amber:~ $
+\end{verbatim}
+To count the size of the routing cache, we have to use the \verb|-o| option
+because cached attributes can take more than one line of output:
+\begin{verbatim}
+kuznet@amber:~ $ ip -o ro ls cloned | wc
+ 159 2543 18707
+kuznet@amber:~ $
+\end{verbatim}
+
+
+\paragraph{Output format:} The output of this command consists
+of per route records separated by line feeds.
+However, some records may consist
+of more than one line: particularly, this is the case when the route
+is cloned or you requested additional statistics. If the
+\verb|-o| option was given, then line feeds separating lines inside
+records are replaced with the backslash sign.
+
+The output has the same syntax as arguments given to {\tt ip route add},
+so that it can be understood easily. F.e.\
+\begin{verbatim}
+kuznet@amber:~ $ ip ro ls 193.233.7/24
+193.233.7.0/24 dev eth0 proto gated/conn scope link \
+ src 193.233.7.65 realms inr.ac
+kuznet@amber:~ $
+\end{verbatim}
+
+If you list cloned entries, the output contains other attributes which
+are evaluated during route calculation and updated during route
+lifetime. An example of the output is:
+\begin{verbatim}
+kuznet@amber:~ $ ip ro ls 193.233.7.82 tab cache
+193.233.7.82 from 193.233.7.82 dev eth0 src 193.233.7.65 \
+ realms inr.ac/inr.ac
+ cache <src-direct,redirect> mtu 1500 rtt 300 iif eth0
+193.233.7.82 dev eth0 src 193.233.7.65 realms inr.ac
+ cache mtu 1500 rtt 300
+kuznet@amber:~ $
+\end{verbatim}
+\begin{NB}
+ \label{NB-strange-route}
+ The route looks a bit strange, doesn't it? Did you notice that
+ it is a path from 193.233.7.82 back to 193.233.82? Well, you will
+ see in the section on \verb|ip route get| (p.\pageref{NB-nature-of-strangeness})
+ how it appeared.
+\end{NB}
+The second line, starting with the word \verb|cache|, shows
+additional attributes which normal routes do not possess.
+Cached flags are summarized in angle brackets:
+\begin{itemize}
+\item \verb|local| --- packets are delivered locally.
+It stands for loopback unicast routes, for broadcast routes
+and for multicast routes, if this host is a member of the corresponding
+group.
+
+\item \verb|reject| --- the path is bad. Any attempt to use it results
+in an error. See attribute \verb|error| below (p.\pageref{IP-ROUTE-GET-error}).
+
+\item \verb|mc| --- the destination is multicast.
+
+\item \verb|brd| --- the destination is broadcast.
+
+\item \verb|src-direct| --- the source is on a directly connected
+interface.
+
+\item \verb|redirected| --- the route was created by an ICMP Redirect.
+
+\item \verb|redirect| --- packets going via this route will
+trigger an ICMP redirect.
+
+\item \verb|fastroute| --- the route is eligible to be used for fastroute.
+
+\item \verb|equalize| --- make packet by packet randomization
+along this path.
+
+\item \verb|dst-nat| --- the destination address requires translation.
+
+\item \verb|src-nat| --- the source address requires translation.
+
+\item \verb|masq| --- the source address requires masquerading.
+This feature disappeared in linux-2.4.
+
+\item \verb|notify| --- ({\em not implemented}) change/deletion
+of this route will trigger RTNETLINK notification.
+\end{itemize}
+
+Then some optional attributes follow:
+\begin{itemize}
+\item \verb|error| --- on \verb|reject| routes it is error code
+returned to local senders when they try to use this route.
+These error codes are translated into ICMP error codes, sent to remote
+senders, according to the rules described above in the subsection
+devoted to route types (p.\pageref{IP-ROUTE-TYPES}).
+\label{IP-ROUTE-GET-error}
+
+\item \verb|expires| --- this entry will expire after this timeout.
+
+\item \verb|iif| --- the packets for this path are expected to arrive
+on this interface.
+\end{itemize}
+
+\paragraph{Statistics:} With the \verb|-statistics| option, more
+information about this route is shown:
+\begin{itemize}
+\item \verb|users| --- the number of users of this entry.
+\item \verb|age| --- shows when this route was last used.
+\item \verb|used| --- the number of lookups of this route since its creation.
+\end{itemize}
+
+\subsection{{\tt ip route save} -- save routing tables}
+\label{IP-ROUTE-SAVE}
+
+\paragraph{Description:} this command saves the contents of the routing
+tables or the route(s) selected by some criteria to standard output.
+
+\paragraph{Arguments:} \verb|ip route save| has the same arguments as
+\verb|ip route show|.
+
+\paragraph{Example:} This saves all the routes to the {\tt saved\_routes}
+file:
+\begin{verbatim}
+dan@caffeine:~ # ip route save > saved_routes
+\end{verbatim}
+
+\paragraph{Output format:} The format of the data stream provided by
+\verb|ip route save| is that of \verb|rtnetlink|. See
+\verb|rtnetlink(7)| for more information.
+
+\subsection{{\tt ip route restore} -- restore routing tables}
+\label{IP-ROUTE-RESTORE}
+
+\paragraph{Description:} this command restores the contents of the routing
+tables according to a data stream as provided by \verb|ip route save| via
+standard input. Note that any routes already in the table are left unchanged.
+Any routes in the input stream that already exist in the tables are ignored.
+
+\paragraph{Arguments:} This command takes no arguments.
+
+\paragraph{Example:} This restores all routes that were saved to the
+{\tt saved\_routes} file:
+
+\begin{verbatim}
+dan@caffeine:~ # ip route restore < saved_routes
+\end{verbatim}
+
+\subsection{{\tt ip route flush} --- flush routing tables}
+\label{IP-ROUTE-FLUSH}
+
+\paragraph{Abbreviations:} \verb|flush|, \verb|f|.
+
+\paragraph{Description:} this command flushes routes selected
+by some criteria.
+
+\paragraph{Arguments:} the arguments have the same syntax and semantics
+as the arguments of \verb|ip route show|, but routing tables are not
+listed but purged. The only difference is the default action: \verb|show|
+dumps all the IP main routing table but \verb|flush| prints the helper page.
+The reason for this difference does not require any explanation, does it?
+
+
+\paragraph{Statistics:} With the \verb|-statistics| option, the command
+becomes verbose. It prints out the number of deleted routes and the number
+of rounds made to flush the routing table. If the option is given
+twice, \verb|ip route flush| also dumps all the deleted routes
+in the format described in the previous subsection.
+
+\paragraph{Examples:} The first example flushes all the
+gatewayed routes from the main table (f.e.\ after a routing daemon crash).
+\begin{verbatim}
+netadm@amber:~ # ip -4 ro flush scope global type unicast
+\end{verbatim}
+This option deserves to be put into a scriptlet \verb|routef|.
+\begin{NB}
+This option was described in the \verb|route(8)| man page borrowed
+from BSD, but was never implemented in Linux.
+\end{NB}
+
+The second example flushes all IPv6 cloned routes:
+\begin{verbatim}
+netadm@amber:~ # ip -6 -s -s ro flush cache
+3ffe:2400::220:afff:fef4:c5d1 via 3ffe:2400::220:afff:fef4:c5d1 \

+
+*** Round 1, deleting 6 entries ***
+*** Flush is complete after 1 round ***
+netadm@amber:~ # ip -6 -s -s ro flush cache
+Nothing to flush.
+netadm@amber:~ #
+\end{verbatim}
+
+The third example flushes BGP routing tables after a \verb|gated|
+death.
+\begin{verbatim}
+netadm@amber:~ # ip ro ls proto gated/bgp | wc
+ 1408 9856 78730
+netadm@amber:~ # ip -s ro f proto gated/bgp
+
+*** Round 1, deleting 1408 entries ***
+*** Flush is complete after 1 round ***
+netadm@amber:~ # ip ro f proto gated/bgp
+Nothing to flush.
+netadm@amber:~ # ip ro ls proto gated/bgp
+netadm@amber:~ #
+\end{verbatim}
+

+\subsection{{\tt ip route get} --- get a single route}
+\label{IP-ROUTE-GET}
+
+\paragraph{Abbreviations:} \verb|get|, \verb|g|.
+
+\paragraph{Description:} this command gets a single route to a destination
+and prints its contents exactly as the kernel sees it.
+
+\paragraph{Arguments:}
+\begin{itemize}
+\item \verb|to ADDRESS| (default)
+
+--- the destination address.
+
+\item \verb|from ADDRESS|
+
+--- the source address.
+
+\item \verb|tos TOS| or \verb|dsfield TOS|
+
+--- the Type Of Service.
+
+\item \verb|iif NAME|
+
+--- the device from which this packet is expected to arrive.
+
+\item \verb|oif NAME|
+
+--- force the output device on which this packet will be routed.
+
+\item \verb|connected|
+
+--- if no source address (option \verb|from|) was given, relookup
+the route with the source set to the preferred address received from the first lookup.
+If policy routing is used, it may be a different route.
+
+\end{itemize}
+
+Note that this operation is not equivalent to \verb|ip route show|.
+\verb|show| shows existing routes. \verb|get| resolves them and
+creates new clones if necessary. Essentially, \verb|get|
+is equivalent to sending a packet along this path.
+If the \verb|iif| argument is not given, the kernel creates a route
+to output packets towards the requested destination.
+This is equivalent to pinging the destination
+with a subsequent {\tt ip route ls cache}, however, no packets are
+actually sent. With the \verb|iif| argument, the kernel pretends
+that a packet arrived from this interface and searches for
+a path to forward the packet.
+
+\paragraph{Output format:} This command outputs routes in the same
+format as \verb|ip route ls|.
+
+\paragraph{Examples:}
+\begin{itemize}
+\item Find a route to output packets to 193.233.7.82:
+\begin{verbatim}
+kuznet@amber:~ $ ip route get 193.233.7.82
+193.233.7.82 dev eth0 src 193.233.7.65 realms inr.ac
+ cache mtu 1500 rtt 300
+kuznet@amber:~ $
+\end{verbatim}
+
+\item Find a route to forward packets arriving on \verb|eth0|
+from 193.233.7.82 and destined for 193.233.7.82:
+\begin{verbatim}
+kuznet@amber:~ $ ip r g 193.233.7.82 from 193.233.7.82 iif eth0
+193.233.7.82 from 193.233.7.82 dev eth0 src 193.233.7.65 \
+ realms inr.ac/inr.ac
+ cache <src-direct,redirect> mtu 1500 rtt 300 iif eth0
+kuznet@amber:~ $
+\end{verbatim}
+\begin{NB}
+ \label{NB-nature-of-strangeness}
+ This is the command that created the funny route from 193.233.7.82
+ looped back to 193.233.7.82 (cf.\ NB on~p.\pageref{NB-strange-route}).
+ Note the \verb|redirect| flag on it.
+\end{NB}
+
+\item Find a multicast route for packets arriving on \verb|eth0|
+from host 193.233.7.82 and destined for multicast group 224.2.127.254
+(it is assumed that a multicast routing daemon is running.
+In this case, it is \verb|pimd|)
+\begin{verbatim}
+kuznet@amber:~ $ ip r g 224.2.127.254 from 193.233.7.82 iif eth0
+multicast 224.2.127.254 from 193.233.7.82 dev lo \
+ src 193.233.7.65 realms inr.ac/cosmos
+ cache <mc> iif eth0 Oifs: eth1 pimreg
+kuznet@amber:~ $
+\end{verbatim}
+This route differs from the ones seen before. It contains a ``normal'' part
+and a ``multicast'' part. The normal part is used to deliver (or not to
+deliver) the packet to local IP listeners. In this case the router
+is not a member
+of this group, so that route has no \verb|local| flag and only
+forwards packets. The output device for such entries is always loopback.
+The multicast part consists of an additional \verb|Oifs:| list showing
+the output interfaces.
+\end{itemize}
+
+
+It is time for a more complicated example. Let us add an invalid
+gatewayed route for a destination which is really directly connected:
+\begin{verbatim}
+netadm@alisa:~ # ip route add 193.233.7.98 via 193.233.7.254
+netadm@alisa:~ # ip route get 193.233.7.98
+193.233.7.98 via 193.233.7.254 dev eth0 src 193.233.7.90
+ cache mtu 1500 rtt 3072
+netadm@alisa:~ #
+\end{verbatim}
+and probe it with ping:
+\begin{verbatim}
+netadm@alisa:~ # ping -n 193.233.7.98
+PING 193.233.7.98 (193.233.7.98) from 193.233.7.90 : 56 data bytes

+\section{{\tt ip rule} --- routing policy database management}
+\label{IP-RULE}
+
+\paragraph{Abbreviations:} \verb|rule|, \verb|ru|.
+
+\paragraph{Object:} \verb|rule|s in the routing policy database control
+the route selection algorithm.
+
+Classic routing algorithms used in the Internet make routing decisions
+based only on the destination address of packets (and in theory,
+but not in practice, on the TOS field). The seminal review of classic
+routing algorithms and their modifications can be found in~\cite{RFC1812}.
+
+In some circumstances we want to route packets differently depending not only
+on destination addresses, but also on other packet fields: source address,
+IP protocol, transport protocol ports or even packet payload.
+This task is called ``policy routing''.
+
+\begin{NB}
+ ``policy routing'' $\neq$ ``routing policy''.
+
+\noindent ``policy routing'' $=$ ``cunning routing''.
+
+\noindent ``routing policy'' $=$ ``routing tactics'' or ``routing plan''.
+\end{NB}
+
+To solve this task, the conventional destination based routing table, ordered
+according to the longest match rule, is replaced with a ``routing policy
+database'' (or RPDB), which selects routes
+by executing some set of rules. The rules may have lots of keys of different
+natures and therefore they have no natural ordering, but one imposed
+by the administrator. Linux-2.2 RPDB is a linear list of rules
+ordered by numeric priority value.
+RPDB explicitly allows matching a few packet fields:
+
+\begin{itemize}
+\item packet source address.
+\item packet destination address.
+\item TOS.
+\item incoming interface (which is packet metadata, rather than a packet field).
+\end{itemize}
+
+Matching IP protocols and transport ports is also possible,
+indirectly, via \verb|ipchains|, by exploiting their ability
+to mark some classes of packets with \verb|fwmark|. Therefore,
+\verb|fwmark| is also included in the set of keys checked by rules.
+
+Each policy routing rule consists of a {\em selector\/} and an {\em action\/}
+predicate. The RPDB is scanned in the order of increasing priority. The selector
+of each rule is applied to \{source address, destination address, incoming
+interface, tos, fwmark\} and, if the selector matches the packet,
+the action is performed. The action predicate may return with success.
+In this case, it will either give a route or failure indication
+and the RPDB lookup is terminated. Otherwise, the RPDB program
+continues on the next rule.
+
+What is the action, semantically? The natural action is to select the
+nexthop and the output device. This is what
+Cisco IOS~\cite{IOS} does. Let us call it ``match \& set''.
+The Linux-2.2 approach is more flexible. The action includes
+lookups in destination-based routing tables and selecting
+a route from these tables according to the classic longest match algorithm.
+The ``match \& set'' approach is the simplest case of the Linux one. It is realized
+when a second level routing table contains a single default route.
+Recall that Linux-2.2 supports multiple tables
+managed with the \verb|ip route| command, described in the previous section.
+
+At startup time the kernel configures the default RPDB consisting of three
+rules:
+
+\begin{enumerate}
+\item Priority: 0, Selector: match anything, Action: lookup routing
+table \verb|local| (ID 255).
+The \verb|local| table is a special routing table containing
+high priority control routes for local and broadcast addresses.
+
+Rule 0 is special. It cannot be deleted or overridden.
+
+
+\item Priority: 32766, Selector: match anything, Action: lookup routing
+table \verb|main| (ID 254).
+The \verb|main| table is the normal routing table containing all non-policy
+routes. This rule may be deleted and/or overridden with other
+ones by the administrator.
+
+\item Priority: 32767, Selector: match anything, Action: lookup routing
+table \verb|default| (ID 253).
+The \verb|default| table is empty. It is reserved for some
+post-processing if no previous default rules selected the packet.
+This rule may also be deleted.
+
+\end{enumerate}
+
+Do not confuse routing tables with rules: rules point to routing tables,
+several rules may refer to one routing table and some routing tables
+may have no rules pointing to them. If the administrator deletes all the rules
+referring to a table, the table is not used, but it still exists
+and will disappear only after all the routes contained in it are deleted.
+
+
+\paragraph{Rule attributes:} Each RPDB entry has additional
+attributes. F.e.\ each rule has a pointer to some routing
+table. NAT and masquerading rules have an attribute to select new IP
+address to translate/masquerade. Besides that, rules have some
+optional attributes, which routes have, namely \verb|realms|.
+These values do not override those contained in the routing tables. They
+are only used if the route did not select any attributes.
+
+
+\paragraph{Rule types:} The RPDB may contain rules of the following
+types:
+\begin{itemize}
+\item \verb|unicast| --- the rule prescribes to return the route found
+in the routing table referenced by the rule.
+\item \verb|blackhole| --- the rule prescribes to silently drop the packet.
+\item \verb|unreachable| --- the rule prescribes to generate a ``Network
+is unreachable'' error.
+\item \verb|prohibit| --- the rule prescribes to generate
+``Communication is administratively prohibited'' error.
+\item \verb|nat| --- the rule prescribes to translate the source address
+of the IP packet into some other value. More about NAT is
+in Appendix~\ref{ROUTE-NAT}, p.\pageref{ROUTE-NAT}.
+\end{itemize}
+
+
+\paragraph{Commands:} \verb|add|, \verb|delete| and \verb|show|
+(or \verb|list|).
+
+\subsection{{\tt ip rule add} --- insert a new rule\\
+ {\tt ip rule delete} --- delete a rule}
+\label{IP-RULE-ADD}
+
+\paragraph{Abbreviations:} \verb|add|, \verb|a|; \verb|delete|, \verb|del|,
+ \verb|d|.
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+\item \verb|type TYPE| (default)
+
+--- the type of this rule. The list of valid types was given in the previous
+subsection.
+
+\item \verb|from PREFIX|
+
+--- select the source prefix to match.
+
+\item \verb|to PREFIX|
+
+--- select the destination prefix to match.
+
+\item \verb|iif NAME|
+
+--- select the incoming device to match. If the interface is loopback,
+the rule only matches packets originating from this host. This means that you
+may create separate routing tables for forwarded and local packets and,
+hence, completely segregate them.
+
+\item \verb|tos TOS| or \verb|dsfield TOS|
+
+--- select the TOS value to match.
+
+\item \verb|fwmark MARK|
+
+--- select the \verb|fwmark| value to match.
+
+\item \verb|priority PREFERENCE|
+
+--- the priority of this rule. Each rule should have an explicitly
+set {\em unique\/} priority value.
+\begin{NB}
+ Really, for historical reasons \verb|ip rule add| does not require a
+ priority value and allows them to be non-unique.
+ If the user does not supplied a priority, it is selected by the kernel.
+ If the user creates a rule with a priority value that
+ already exists, the kernel does not reject the request. It adds
+ the new rule before all old rules of the same priority.
+
+ It is mistake in design, no more. And it will be fixed one day,
+ so do not rely on this feature. Use explicit priorities.
+\end{NB}
+
+
+\item \verb|table TABLEID|
+
+--- the routing table identifier to lookup if the rule selector matches.
+
+\item \verb|realms FROM/TO|
+
+--- Realms to select if the rule matched and the routing table lookup
+succeeded. Realm \verb|TO| is only used if the route did not select
+any realm.
+
+\item \verb|nat ADDRESS|
+
+--- The base of the IP address block to translate (for source addresses).
+The \verb|ADDRESS| may be either the start of the block of NAT addresses
+(selected by NAT routes) or in linux-2.2 a local host address (or even zero).
+In the last case the router does not translate the packets,
+but masquerades them to this address; this feature disappered in 2.4.
+More about NAT is in Appendix~\ref{ROUTE-NAT},
+p.\pageref{ROUTE-NAT}.
+
+\end{itemize}
+
+\paragraph{Warning:} Changes to the RPDB made with these commands
+do not become active immediately. It is assumed that after
+a script finishes a batch of updates, it flushes the routing cache
+with \verb|ip route flush cache|.
+
+\paragraph{Examples:}
+\begin{itemize}
+\item Route packets with source addresses from 192.203.80/24
+according to routing table \verb|inr.ruhep|:
+\begin{verbatim}
+ip ru add from 192.203.80.0/24 table inr.ruhep prio 220
+\end{verbatim}
+
+\item Translate packet source address 193.233.7.83 into 192.203.80.144
+and route it according to table \#1 (actually, it is \verb|inr.ruhep|):
+\begin{verbatim}
+ip ru add from 193.233.7.83 nat 192.203.80.144 table 1 prio 320
+\end{verbatim}
+
+\item Delete the unused default rule:
+\begin{verbatim}
+ip ru del prio 32767
+\end{verbatim}
+
+\end{itemize}
+
+
+
+\subsection{{\tt ip rule show} --- list rules}
+\label{IP-RULE-SHOW}
+
+\paragraph{Abbreviations:} \verb|show|, \verb|list|, \verb|sh|, \verb|ls|, \verb|l|.
+
+
+\paragraph{Arguments:} Good news, this is one command that has no arguments.
+
+\paragraph{Output format:}
+
+\begin{verbatim}
+kuznet@amber:~ $ ip ru ls
+0: from all lookup local
+200: from 192.203.80.0/24 to 193.233.7.0/24 lookup main
+210: from 192.203.80.0/24 to 192.203.80.0/24 lookup main
+220: from 192.203.80.0/24 lookup inr.ruhep realms inr.ruhep/radio-msu
+300: from 193.233.7.83 to 193.233.7.0/24 lookup main
+310: from 193.233.7.83 to 192.203.80.0/24 lookup main
+320: from 193.233.7.83 lookup inr.ruhep map-to 192.203.80.144
+32766: from all lookup main
+kuznet@amber:~ $
+\end{verbatim}
+
+In the first column is the rule priority value followed
+by a colon. Then the selectors follow. Each key is prefixed
+with the same keyword that was used to create the rule.
+
+The keyword \verb|lookup| is followed by a routing table identifier,
+as it is recorded in the file \verb|/etc/iproute2/rt_tables|.
+
+If the rule does NAT (f.e.\ rule \#320), it is shown by the keyword
+\verb|map-to| followed by the start of the block of addresses to map.
+
+The sense of this example is pretty simple. The prefixes
+192.203.80.0/24 and 193.233.7.0/24 form the internal network, but
+they are routed differently when the packets leave it.
+Besides that, the host 193.233.7.83 is translated into
+another prefix to look like 192.203.80.144 when talking
+to the outer world.
+
+\subsection{{\tt ip rule save} -- save rules tables}
+\label{IP-RULE-SAVE}
+
+\paragraph{Description:} this command saves the contents of the rules

+\section{{\tt ip maddress} --- multicast addresses management}
+\label{IP-MADDR}
+
+\paragraph{Object:} \verb|maddress| objects are multicast addresses.
+
+\paragraph{Commands:} \verb|add|, \verb|delete|, \verb|show| (or \verb|list|).
+
+\subsection{{\tt ip maddress show} --- list multicast addresses}
+
+\paragraph{Abbreviations:} \verb|show|, \verb|list|, \verb|sh|, \verb|ls|, \verb|l|.
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+
+\item \verb|dev NAME| (default)
+
+--- the device name.
+
+\end{itemize}
+
+\paragraph{Output format:}
+
+\begin{verbatim}
+kuznet@alisa:~ $ ip maddr ls dummy
+2: dummy
+ link 33:33:00:00:00:01
+ link 01:00:5e:00:00:01
+ inet 224.0.0.1 users 2
+ inet6 ff02::1
+kuznet@alisa:~ $
+\end{verbatim}
+
+The first line of the output shows the interface index and its name.
+Then the multicast address list follows. Each line starts with the
+protocol identifier. The word \verb|link| denotes a link layer
+multicast addresses.
+
+If a multicast address has more than one user, the number
+of users is shown after the \verb|users| keyword.
+
+One additional feature not present in the example above
+is the \verb|static| flag, which indicates that the address was joined
+with \verb|ip maddr add|. See the following subsection.
+
+
+
+\subsection{{\tt ip maddress add} --- add a multicast address\\
+ {\tt ip maddress delete} --- delete a multicast address}
+
+\paragraph{Abbreviations:} \verb|add|, \verb|a|; \verb|delete|, \verb|del|, \verb|d|.
+
+\paragraph{Description:} these commands attach/detach
+a static link layer multicast address to listen on the interface.
+Note that it is impossible to join protocol multicast groups
+statically. This command only manages link layer addresses.
+
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+\item \verb|address LLADDRESS| (default)
+
+--- the link layer multicast address.
+
+\item \verb|dev NAME|
+
+--- the device to join/leave this multicast address.
+
+\end{itemize}
+
+
+\paragraph{Example:} Let us continue with the example from the previous subsection.
+
+\begin{verbatim}
+netadm@alisa:~ # ip maddr add 33:33:00:00:00:01 dev dummy
+netadm@alisa:~ # ip -0 maddr ls dummy
+2: dummy
+ link 33:33:00:00:00:01 users 2 static
+ link 01:00:5e:00:00:01
+netadm@alisa:~ # ip maddr del 33:33:00:00:00:01 dev dummy
+\end{verbatim}
+
+\begin{NB}
+ Neither \verb|ip| nor the kernel check for multicast address validity.
+ Particularly, this means that you can try to load a unicast address
+ instead of a multicast address. Most drivers will ignore such addresses,
+ but several (f.e.\ Tulip) will intern it to their on-board filter.
+ The effects may be strange. Namely, the addresses become additional
+ local link addresses and, if you loaded the address of another host
+ to the router, wait for duplicated packets on the wire.
+ It is not a bug, but rather a hole in the API and intra-kernel interfaces.
+ This feature is really more useful for traffic monitoring, but using it
+ with Linux-2.2 you {\em have to\/} be sure that the host is not
+ a router and, especially, that it is not a transparent proxy or masquerading
+ agent.
+\end{NB}

+\section{{\tt ip mroute} --- multicast routing cache management}
+\label{IP-MROUTE}
+
+\paragraph{Abbreviations:} \verb|mroute|, \verb|mr|.
+
+\paragraph{Object:} \verb|mroute| objects are multicast routing cache
+entries created by a user level mrouting daemon
+(f.e.\ \verb|pimd| or \verb|mrouted|).
+
+Due to the limitations of the current interface to the multicast routing
+engine, it is impossible to change \verb|mroute| objects administratively,
+so we may only display them. This limitation will be removed
+in the future.
+
+\paragraph{Commands:} \verb|show| (or \verb|list|).
+
+
+\subsection{{\tt ip mroute show} --- list mroute cache entries}
+
+\paragraph{Abbreviations:} \verb|show|, \verb|list|, \verb|sh|, \verb|ls|, \verb|l|.
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+\item \verb|to PREFIX| (default)
+
+--- the prefix selecting the destination multicast addresses to list.
+
+
+\item \verb|iif NAME|
+
+--- the interface on which multicast packets are received.
+
+
+\item \verb|from PREFIX|
+
+--- the prefix selecting the IP source addresses of the multicast route.
+
+
+\end{itemize}
+
+\paragraph{Output format:}
+
+\begin{verbatim}
+kuznet@amber:~ $ ip mroute ls
+(193.232.127.6, 224.0.1.39) Iif: unresolved
+(193.232.244.34, 224.0.1.40) Iif: unresolved
+(193.233.7.65, 224.66.66.66) Iif: eth0 Oifs: pimreg
+kuznet@amber:~ $
+\end{verbatim}
+
+Each line shows one (S,G) entry in the multicast routing cache,
+where S is the source address and G is the multicast group. \verb|Iif| is
+the interface on which multicast packets are expected to arrive.
+If the word \verb|unresolved| is there instead of the interface name,
+it means that the routing daemon still hasn't resolved this entry.
+The keyword \verb|oifs| is followed by a list of output interfaces, separated
+by spaces. If a multicast routing entry is created with non-trivial
+TTL scope, administrative distances are appended to the device names
+in the \verb|oifs| list.
+
+\paragraph{Statistics:} The \verb|-statistics| option also prints the
+number of packets and bytes forwarded along this route and
+the number of packets that arrived on the wrong interface, if this number is not zero.
+
+\begin{verbatim}
+kuznet@amber:~ $ ip -s mr ls 224.66/16
+(193.233.7.65, 224.66.66.66) Iif: eth0 Oifs: pimreg

+\section{{\tt ip tunnel} --- tunnel configuration}
+\label{IP-TUNNEL}
+
+\paragraph{Abbreviations:} \verb|tunnel|, \verb|tunl|.
+
+\paragraph{Object:} \verb|tunnel| objects are tunnels, encapsulating
+packets in IPv4 packets and then sending them over the IP infrastructure.
+
+\paragraph{Commands:} \verb|add|, \verb|delete|, \verb|change|, \verb|show|
+(or \verb|list|).
+
+\paragraph{See also:} A more informal discussion of tunneling
+over IP and the \verb|ip tunnel| command can be found in~\cite{IP-TUNNELS}.
+
+\subsection{{\tt ip tunnel add} --- add a new tunnel\\
+ {\tt ip tunnel change} --- change an existing tunnel\\
+ {\tt ip tunnel delete} --- destroy a tunnel}
+
+\paragraph{Abbreviations:} \verb|add|, \verb|a|; \verb|change|, \verb|chg|;
+\verb|delete|, \verb|del|, \verb|d|.
+
+
+\paragraph{Arguments:}
+
+\begin{itemize}
+
+\item \verb|name NAME| (default)
+
+--- select the tunnel device name.
+
+\item \verb|mode MODE|
+
+--- set the tunnel mode. Three modes are currently available:
+ \verb|ipip|, \verb|sit| and \verb|gre|.
+
+\item \verb|remote ADDRESS|
+
+--- set the remote endpoint of the tunnel.
+
+\item \verb|local ADDRESS|
+
+--- set the fixed local address for tunneled packets.
+It must be an address on another interface of this host.
+
+\item \verb|ttl N|
+
+--- set a fixed TTL \verb|N| on tunneled packets.
+ \verb|N| is a number in the range 1--255. 0 is a special value
+ meaning that packets inherit the TTL value.
+ The default value is: \verb|inherit|.
+
+\item \verb|tos T| or \verb|dsfield T|
+
+--- set a fixed TOS \verb|T| on tunneled packets.
+ The default value is: \verb|inherit|.
+
+
+
+\item \verb|dev NAME|
+
+--- bind the tunnel to the device \verb|NAME| so that
+ tunneled packets will only be routed via this device and will
+ not be able to escape to another device when the route to endpoint changes.
+
+\item \verb|nopmtudisc|
+
+--- disable Path MTU Discovery on this tunnel.
+ It is enabled by default. Note that a fixed ttl is incompatible
+ with this option: tunnelling with a fixed ttl always makes pmtu discovery.
+
+\item \verb|key K|, \verb|ikey K|, \verb|okey K|
+
+--- (only GRE tunnels) use keyed GRE with key \verb|K|. \verb|K| is
+ either a number or an IP address-like dotted quad.
+ The \verb|key| parameter sets the key to use in both directions.
+ The \verb|ikey| and \verb|okey| parameters set different keys for input and output.
+
+
+\item \verb|csum|, \verb|icsum|, \verb|ocsum|
+
+--- (only GRE tunnels) generate/require checksums for tunneled packets.
+ The \verb|ocsum| flag calculates checksums for outgoing packets.
+ The \verb|icsum| flag requires that all input packets have the correct
+ checksum. The \verb|csum| flag is equivalent to the combination
+ ``\verb|icsum| \verb|ocsum|''.
+
+\item \verb|seq|, \verb|iseq|, \verb|oseq|
+
+--- (only GRE tunnels) serialize packets.
+ The \verb|oseq| flag enables sequencing of outgoing packets.
+ The \verb|iseq| flag requires that all input packets are serialized.
+ The \verb|seq| flag is equivalent to the combination ``\verb|iseq| \verb|oseq|''.
+
+\begin{NB}
+ I think this option does not
+ work. At least, I did not test it, did not debug it and
+ do not even understand how it is supposed to work or for what
+ purpose Cisco planned to use it. Do not use it.
+\end{NB}
+
+
+\end{itemize}
+
+\paragraph{Example:} Create a pointopoint IPv6 tunnel with maximal TTL of 32.
+\begin{verbatim}
+netadm@amber:~ # ip tunl add Cisco mode sit remote 192.31.7.104 \
+ local 192.203.80.142 ttl 32
+\end{verbatim}
+
+\subsection{{\tt ip tunnel show} --- list tunnels}
+
+\paragraph{Abbreviations:} \verb|show|, \verb|list|, \verb|sh|, \verb|ls|, \verb|l|.
+
+
+\paragraph{Arguments:} None.
+
+\paragraph{Output format:}
+\begin{verbatim}
+kuznet@amber:~ $ ip tunl ls Cisco
+Cisco: ipv6/ip remote 192.31.7.104 local 192.203.80.142 ttl 32
+kuznet@amber:~ $
+\end{verbatim}
+The line starts with the tunnel device name followed by a colon.
+Then the tunnel mode follows. The parameters of the tunnel are listed
+with the same keywords that were used when creating the tunnel.
+
+\paragraph{Statistics:}
+
+\begin{verbatim}
+kuznet@amber:~ $ ip -s tunl ls Cisco
+Cisco: ipv6/ip remote 192.31.7.104 local 192.203.80.142 ttl 32

+TX: Packets Bytes Errors DeadLoop NoRoute NoBufs
+ 13445 1879677 0 0 0 0
+kuznet@amber:~ $
+\end{verbatim}
+Essentially, these numbers are the same as the numbers
+printed with {\tt ip -s link show}
+(sec.\ref{IP-LINK-SHOW}, p.\pageref{IP-LINK-SHOW}) but the tags are different
+to reflect that they are tunnel specific.
+\begin{itemize}
+\item \verb|CsumErrs| --- the total number of packets dropped
+because of checksum failures for a GRE tunnel with checksumming enabled.
+\item \verb|OutOfSeq| --- the total number of packets dropped
+because they arrived out of sequence for a GRE tunnel with
+serialization enabled.
+\item \verb|Mcasts| --- the total number of multicast packets
+received on a broadcast GRE tunnel.
+\item \verb|DeadLoop| --- the total number of packets which were not
+transmitted because the tunnel is looped back to itself.
+\item \verb|NoRoute| --- the total number of packets which were not
+transmitted because there is no IP route to the remote endpoint.
+\item \verb|NoBufs| --- the total number of packets which were not
+transmitted because the kernel failed to allocate a buffer.
+\end{itemize}
+
+
+\section{{\tt ip monitor} and {\tt rtmon} --- state monitoring}
+\label{IP-MONITOR}
+
+The \verb|ip| utility can monitor the state of devices, addresses
+and routes continuously. This option has a slightly different format.
+Namely,
+the \verb|monitor| command is the first in the command line and then
+the object list follows:
+\begin{verbatim}
+ ip monitor [ file FILE ] [ all | OBJECT-LIST ] [ label ]
+\end{verbatim}
+\verb|OBJECT-LIST| is the list of object types that we want to
+monitor. It may contain \verb|link|, \verb|address| and \verb|route|.
+Specifying \verb|label| indicates that output lines should be labelled
+with the type of object being printed --- this happens by default if
+\verb|all| is specified. If no \verb|file| argument is given,
+\verb|ip| opens RTNETLINK, listens on it and dumps state changes in
+the format described in previous sections.
+
+If a file name is given, it does not listen on RTNETLINK,
+but opens the file containing RTNETLINK messages saved in binary format
+and dumps them. Such a history file can be generated with the
+\verb|rtmon| utility. This utility has a command line syntax similar to
+\verb|ip monitor|.
+Ideally, \verb|rtmon| should be started before
+the first network configuration command is issued. F.e.\ if
+you insert:
+\begin{verbatim}
+ rtmon file /var/log/rtmon.log
+\end{verbatim}
+in a startup script, you will be able to view the full history
+later.
+
+Certainly, it is possible to start \verb|rtmon| at any time.
+It prepends the history with the state snapshot dumped at the moment
+of starting.
+
+
+\section{Route realms and policy propagation, {\tt rtacct}}
+\label{RT-REALMS}
+
+On routers using OSPF ASE or, especially, the BGP protocol, routing
+tables may be huge. If we want to classify or to account for the packets
+per route, we will have to keep lots of information. Even worse, if we
+want to distinguish the packets not only by their destination, but
+also by their source, the task gets quadratic complexity and its solution
+is physically impossible.
+
+One approach to propagating the policy from routing protocols
+to the forwarding engine has been proposed in~\cite{IOS-BGP-PP}.
+Essentially, Cisco Policy Propagation via BGP is based on the fact
+that dedicated routers all have the RIB (Routing Information Base)
+close to the forwarding engine, so policy routing rules can
+check all the route attributes, including ASPATH information
+and community strings.
+
+The Linux architecture, splitting the RIB (maintained by a user level
+daemon) and the kernel based FIB (Forwarding Information Base),
+does not allow such a simple approach.
+
+It is to our fortune because there is another solution
+which allows even more flexible policy and richer semantics.
+
+Namely, routes can be clustered together in user space, based on their
+attributes. F.e.\ a BGP router knows route ASPATH, its community;
+an OSPF router knows the route tag or its area. The administrator, when adding
+routes manually, also knows their nature. Providing that the number of such
+aggregates (we call them {\em realms\/}) is low, the task of full
+classification both by source and destination becomes quite manageable.
+
+So each route may be assigned to a realm. It is assumed that
+this identification is made by a routing daemon, but static routes
+can also be handled manually with \verb|ip route| (see sec.\ref{IP-ROUTE},
+p.\pageref{IP-ROUTE}).
+\begin{NB}
+ There is a patch to \verb|gated|, allowing classification of routes
+ to realms with all the set of policy rules implemented in \verb|gated|:
+ by prefix, by ASPATH, by origin, by tag etc.
+\end{NB}
+
+To facilitate the construction (f.e.\ in case the routing
+daemon is not aware of realms), missing realms may be completed
+with routing policy rules, see sec.~\ref{IP-RULE}, p.\pageref{IP-RULE}.
+
+For each packet the kernel calculates a tuple of realms: source realm
+and destination realm, using the following algorithm:
+
+\begin{enumerate}
+\item If the route has a realm, the destination realm of the packet is set to it.
+\item If the rule has a source realm, the source realm of the packet is set to it.
+If the destination realm was not inherited from the route and the rule has a destination realm,
+it is also set.
+\item If at least one of the realms is still unknown, the kernel finds
+the reversed route to the source of the packet.
+\item If the source realm is still unknown, get it from the reversed route.
+\item If one of the realms is still unknown, swap the realms of reversed
+routes and apply step 2 again.
+\end{enumerate}
+
+After this procedure is completed we know what realm the packet
+arrived from and the realm where it is going to propagate to.
+If some of the realms are unknown, they are initialized to zero
+(or realm \verb|unknown|).
+
+The main application of realms is the TC \verb|route| classifier~\cite{TC-CREF},
+where they are used to help assign packets to traffic classes,
+to account, police and schedule them according to this
+classification.
+
+A much simpler but still very useful application is incoming packet
+accounting by realms. The kernel gathers a packet statistics summary
+which can be viewed with the \verb|rtacct| utility.
+\begin{verbatim}
+kuznet@amber:~ $ rtacct russia
+Realm BytesTo PktsTo BytesFrom PktsFrom
+russia 20576778 169176 47080168 153805
+kuznet@amber:~ $
+\end{verbatim}
+This shows that this router received 153805 packets from
+the realm \verb|russia| and forwarded 169176 packets to \verb|russia|.
+The realm \verb|russia| consists of routes with ASPATHs not leaving
+Russia.
+
+Note that locally originating packets are not accounted here,
+\verb|rtacct| shows incoming packets only. Using the \verb|route|
+classifier (see~\cite{TC-CREF}) you can get even more detailed
+accounting information about outgoing packets, optionally
+summarizing traffic not only by source or destination, but
+by any pair of source and destination realms.

+
+\section{Source address selection}
+\label{ADDR-SEL}
+
+When a host creates an IP packet, it must select some source
+address. Correct source address selection is a critical procedure,
+because it gives the receiver the information needed to deliver a
+reply. If the source is selected incorrectly, in the best case,
+the backward path may appear different to the forward one which
+is harmful for performance. In the worst case, when the addresses
+are administratively scoped, the reply may be lost entirely.
+
+Linux-2.2 selects source addresses using the following algorithm:
+
+\begin{itemize}
+\item
+The application may select a source address explicitly with \verb|bind(2)|
+syscall or supplying it to \verb|sendmsg(2)| via the ancillary data object
+\verb|IP_PKTINFO|. In this case the kernel only checks the validity
+of the address and never tries to ``improve'' an incorrect user choice,
+generating an error instead.
+\begin{NB}
+ Never say ``Never''. The sysctl option \verb|ip_dynaddr| breaks
+ this axiom. It has been made deliberately with the purpose
+ of automatically reselecting the address on hosts with dynamic dial-out interfaces.
+ However, this hack {\em must not\/} be used on multihomed hosts
+ and especially on routers: it would break them.
+\end{NB}
+
+
+\item Otherwise, IP routing tables can contain an explicit source
+address hint for this destination. The hint is set with the \verb|src| parameter
+to the \verb|ip route| command, sec.\ref{IP-ROUTE}, p.\pageref{IP-ROUTE}.
+
+
+\item Otherwise, the kernel searches through the list of addresses
+attached to the interface through which the packets will be routed.
+The search strategies are different for IP and IPv6. Namely:
+
+\begin{itemize}
+\item IPv6 searches for the first valid, not deprecated address
+with the same scope as the destination.
+
+\item IP searches for the first valid address with a scope wider
+than the scope of the destination but it prefers addresses
+which fall to the same subnet as the nexthop of the route
+to the destination. Unlike IPv6, the scopes of IPv4 destinations
+are not encoded in their addresses but are supplied
+in routing tables instead (the \verb|scope| parameter to the \verb|ip route| command,
+sec.\ref{IP-ROUTE}, p.\pageref{IP-ROUTE}).
+
+\end{itemize}
+
+
+\item Otherwise, if the scope of the destination is \verb|link| or \verb|host|,
+the algorithm fails and returns a zero source address.
+
+\item Otherwise, all interfaces are scanned to search for an address
+with an appropriate scope. The loopback device \verb|lo| is always the first
+in the search list, so that if an address with global scope (not 127.0.0.1!)
+is configured on loopback, it is always preferred.
+
+\end{itemize}
+
+
+\section{Proxy ARP/NDISC}
+\label{PROXY-NEIGH}
+
+Routers may answer ARP/NDISC solicitations on behalf of other hosts.
+In Linux-2.2 proxy ARP on an interface may be enabled
+by setting the kernel \verb|sysctl| variable
+\verb|/proc/sys/net/ipv4/conf/<dev>/proxy_arp| to 1. After this, the router
+starts to answer ARP requests on the interface \verb|<dev>|, provided
+the route to the requested destination does {\em not\/} go back via the same
+device.
+
+The variable \verb|/proc/sys/net/ipv4/conf/all/proxy_arp| enables proxy
+ARP on all the IP devices.
+
+However, this approach fails in the case of IPv6 because the router
+must join the solicited node multicast address to listen for the corresponding
+NDISC queries. It means that proxy NDISC is possible only on a per destination
+basis.
+
+Logically, proxy ARP/NDISC is not a kernel task. It can easily be implemented
+in user space. However, similar functionality was present in BSD kernels
+and in Linux-2.0, so we have to preserve it at least to the extent that
+is standardized in BSD.
+\begin{NB}
+ Linux-2.0 ARP had a feature called {\em subnet\/} proxy ARP.
+ It is replaced with the sysctl flag in Linux-2.2.
+\end{NB}
+
+
+The \verb|ip| utility provides a way to manage proxy ARP/NDISC
+with the \verb|ip neigh| command, namely:
+\begin{verbatim}
+ ip neigh add proxy ADDRESS [ dev NAME ]
+\end{verbatim}
+adds a new proxy ARP/NDISC record and
+\begin{verbatim}
+ ip neigh del proxy ADDRESS [ dev NAME ]
+\end{verbatim}
+deletes it.
+
+If the name of the device is not given, the router will answer solicitations
+for address \verb|ADDRESS| on all devices, otherwise it will only serve
+the device \verb|NAME|. Even if the proxy entry is created with
+\verb|ip neigh|, the router {\em will not\/} answer a query if the route
+to the destination goes back via the interface from which the solicitation
+was received.
+
+It is important to emphasize that proxy entries have {\em no\/}
+parameters other than these (IP/IPv6 address and optional device).
+Particularly, the entry does not store any link layer address.
+It always advertises the station address of the interface
+on which it sends advertisements (i.e. it's own station address).
+
+\section{Route NAT status}
+\label{ROUTE-NAT}
+
+NAT (or ``Network Address Translation'') remaps some parts
+of the IP address space into other ones. Linux-2.2 route NAT is supposed
+to be used to facilitate policy routing by rewriting addresses
+to other routing domains or to help while renumbering sites
+to another prefix.
+
+\paragraph{What it is not:}
+It is necessary to emphasize that {\em it is not supposed\/}
+to be used to compress address space or to split load.
+This is not missing functionality but a design principle.
+Route NAT is {\em stateless\/}. It does not hold any state
+about translated sessions. This means that it handles any number
+of sessions flawlessly. But it also means that it is {\em static\/}.
+It cannot detect the moment when the last TCP client stops
+using an address. For the same reason, it will not help to split
+load between several servers.
+\begin{NB}
+It is a pretty commonly held belief that it is useful to split load between
+several servers with NAT. This is a mistake. All you get from this
+is the requirement that the router keep the state of all the TCP connections
+going via it. Well, if the router is so powerful, run apache on it. 8)
+\end{NB}
+
+The second feature: it does not touch packet payload,
+does not try to ``improve'' broken protocols by looking
+through its data and mangling it. It mangles IP addresses,
+only IP addresses and nothing but IP addresses.
+This also, is not missing any functionality.
+
+To resume: if you need to compress address space or keep
+active FTP clients happy, your choice is not route NAT but masquerading,
+port forwarding, NAPT etc.
+\begin{NB}
+By the way, you may also want to look at
+http://www.suse.com/\~mha/HyperNews/get/linux-ip-nat.html
+\end{NB}
+
+
+\paragraph{How it works.}
+Some part of the address space is reserved for dummy addresses
+which will look for all the world like some host addresses
+inside your network. No other hosts may use these addresses,
+however other routers may also be configured to translate them.
+\begin{NB}
+A great advantage of route NAT is that it may be used not
+only in stub networks but in environments with arbitrarily complicated
+structure. It does not firewall, it {\em forwards.}
+\end{NB}
+These addresses are selected by the \verb|ip route| command
+(sec.\ref{IP-ROUTE-ADD}, p.\pageref{IP-ROUTE-ADD}). F.e.\
+\begin{verbatim}
+ ip route add nat 192.203.80.144 via 193.233.7.83
+\end{verbatim}
+states that the single address 192.203.80.144 is a dummy NAT address.
+For all the world it looks like a host address inside our network.
+For neighbouring hosts and routers it looks like the local address
+of the translating router. The router answers ARP for it, advertises
+this address as routed via it, {\em et al\/}. When the router
+receives a packet destined for 192.203.80.144, it replaces
+this address with 193.233.7.83 which is the address of some real
+host and forwards the packet. If you need to remap
+blocks of addresses, you may use a command like:
+\begin{verbatim}
+ ip route add nat 192.203.80.192/26 via 193.233.7.64
+\end{verbatim}
+This command will map a block of 63 addresses 192.203.80.192-255 to
+193.233.7.64-127.
+
+When an internal host (193.233.7.83 in the example above)
+sends something to the outer world and these packets are forwarded
+by our router, it should translate the source address 193.233.7.83
+into 192.203.80.144. This task is solved by setting a special
+policy rule (sec.\ref{IP-RULE-ADD}, p.\pageref{IP-RULE-ADD}):
+\begin{verbatim}
+ ip rule add prio 320 from 193.233.7.83 nat 192.203.80.144
+\end{verbatim}
+This rule says that the source address 193.233.7.83
+should be translated into 192.203.80.144 before forwarding.
+It is important that the address after the \verb|nat| keyword
+is some NAT address, declared by {\tt ip route add nat}.
+If it is just a random address the router will not map to it.
+\begin{NB}
+The exception is when the address is a local address of this
+router (or 0.0.0.0) and masquerading is configured in the linux-2.2
+kernel. In this case the router will masquerade the packets as this address.
+If 0.0.0.0 is selected, the result is equivalent to one
+obtained with firewalling rules. Otherwise, you have the way
+to order Linux to masquerade to this fixed address.
+NAT mechanism used in linux-2.4 is more flexible than
+masquerading, so that this feature has lost meaning and disabled.
+\end{NB}
+
+If the network has non-trivial internal structure, it is
+useful and even necessary to add rules disabling translation
+when a packet does not leave this network. Let us return to the
+example from sec.\ref{IP-RULE-SHOW} (p.\pageref{IP-RULE-SHOW}).
+\begin{verbatim}
+300: from 193.233.7.83 to 193.233.7.0/24 lookup main
+310: from 193.233.7.83 to 192.203.80.0/24 lookup main
+320: from 193.233.7.83 lookup inr.ruhep map-to 192.203.80.144
+\end{verbatim}
+This block of rules causes normal forwarding when
+packets from 193.233.7.83 do not leave networks 193.233.7/24
+and 192.203.80/24. Also, if the \verb|inr.ruhep| table does not
+contain a route to the destination (which means that the routing
+domain owning addresses from 192.203.80/24 is dead), no translation
+will occur. Otherwise, the packets are translated.
+
+\paragraph{How to only translate selected ports:}
+If you only want to translate selected ports (f.e.\ http)
+and leave the rest intact, you may use \verb|ipchains|
+to \verb|fwmark| a class of packets.
+Suppose you did and all the packets from 193.233.7.83
+destined for port 80 are marked with marker 0x1234 in input fwchain.
+In this case you may replace rule \#320 with:
+\begin{verbatim}
+320: from 193.233.7.83 fwmark 1234 lookup main map-to 192.203.80.144
+\end{verbatim}
+and translation will only be enabled for outgoing http requests.
+
+\section{Example: minimal host setup}
+\label{EXAMPLE-SETUP}
+
+The following script gives an example of a fault safe
+setup of IP (and IPv6, if it is compiled into the kernel)
+in the common case of a node attached to a single broadcast
+network. A more advanced script, which may be used both on multihomed
+hosts and on routers, is described in the following
+section.
+
+The utilities used in the script may be found in the
+directory ftp://ftp.inr.ac.ru/ip-routing/:
+\begin{enumerate}
+\item \verb|ip| --- package \verb|iproute2|.
+\item \verb|arping| --- package \verb|iputils|.
+\item \verb|rdisc| --- package \verb|iputils|.
+\end{enumerate}
+\begin{NB}
+It also refers to a DHCP client, \verb|dhcpcd|. I should refrain from
+recommending a good DHCP client to use. All that I can
+say is that ISC \verb|dhcp-2.0b1pl6| patched with the patch that
+can be found in the \verb|dhcp.bootp.rarp| subdirectory of
+the same ftp site {\em does\/} work,
+at least on Ethernet and Token Ring.

+\section{Instead of introduction: micro-FAQ.}
+
+\begin{itemize}
+
+\item
+Q: In linux-2.0.36 I used:
+\begin{verbatim}
+ ifconfig tunl1 10.0.0.1 pointopoint 193.233.7.65
+\end{verbatim}
+to create tunnel. It does not work in 2.2.0!
+
+A: You are right, it does not work. The command written above is split to two commands.
+\begin{verbatim}
+ ip tunnel add MY-TUNNEL mode ipip remote 193.233.7.65
+\end{verbatim}
+will create tunnel device with name \verb|MY-TUNNEL|. Now you may configure
+it with:
+\begin{verbatim}
+ ifconfig MY-TUNNEL 10.0.0.1
+\end{verbatim}
+Certainly, if you prefer name \verb|tunl1| to \verb|MY-TUNNEL|,
+you still may use it.
+
+\item
+Q: In linux-2.0.36 I used:
+\begin{verbatim}
+ ifconfig tunl0 10.0.0.1
+ route add -net 10.0.0.0 gw 193.233.7.65 dev tunl0
+\end{verbatim}
+to tunnel net 10.0.0.0 via router 193.233.7.65. It does not
+work in 2.2.0! Moreover, \verb|route| prints a funny error sort of
+``network unreachable'' and after this I found a strange direct route
+to 10.0.0.0 via \verb|tunl0| in routing table.
+
+A: Yes, in 2.2 the rule that {\em normal} gateway must reside on directly
+connected network has not any exceptions. You may tell kernel, that
+this particular route is {\em abnormal}:
+\begin{verbatim}
+ ifconfig tunl0 10.0.0.1 netmask 255.255.255.255
+ ip route add 10.0.0.0/8 via 193.233.7.65 dev tunl0 onlink
+\end{verbatim}
+Note keyword \verb|onlink|, it is the magic key that orders kernel
+not to check for consistency of gateway address.
+Probably, after this explanation you have already guessed another method
+to cheat kernel:
+\begin{verbatim}
+ ifconfig tunl0 10.0.0.1 netmask 255.255.255.255
+ route add -host 193.233.7.65 dev tunl0
+ route add -net 10.0.0.0 netmask 255.0.0.0 gw 193.233.7.65
+ route del -host 193.233.7.65 dev tunl0
+\end{verbatim}
+Well, if you like such tricks, nobody may prohibit you to use them.
+Only do not forget
+that between \verb|route add| and \verb|route del| host 193.233.7.65 is
+unreachable.
+
+\item
+Q: In 2.0.36 I used to load \verb|tunnel| device module and \verb|ipip| module.
+I cannot find any \verb|tunnel| in 2.2!
+
+A: Linux-2.2 has single module \verb|ipip| for both directions of tunneling
+and for all IPIP tunnel devices.
+
+\item
+Q: \verb|traceroute| does not work over tunnel! Well, stop... It works,
+ only skips some number of hops.
+
+A: Yes. By default tunnel driver copies \verb|ttl| value from
+inner packet to outer one. It means that path traversed by tunneled
+packets to another endpoint is not hidden. If you dislike this, or if you
+are going to use some routing protocol expecting that packets
+with ttl 1 will reach peering host (f.e.\ RIP, OSPF or EBGP)
+and you are not afraid of
+tunnel loops, you may append option \verb|ttl 64|, when creating tunnel
+with \verb|ip tunnel add|.
+
+\item
+Q: ... Well, list of things, which 2.0 was able to do finishes.
+
+\end{itemize}
+
+\paragraph{Summary of differences between 2.2 and 2.0.}
+
+\begin{itemize}
+
+\item {\bf In 2.0} you could compile tunnel device into kernel
+ and got set of 4 devices \verb|tunl0| ... \verb|tunl3| or,
+ alternatively, compile it as module and load new module
+ for each new tunnel. Also, module \verb|ipip| was necessary
+ to receive tunneled packets.
+
+ {\bf 2.2} has {\em one\/} module \verb|ipip|. Loading it you get base
+ tunnel device \verb|tunl0| and another tunnels may be created with command
+ \verb|ip tunnel add|. These new devices may have arbitrary names.
+
+
+\item {\bf In 2.0} you set remote tunnel endpoint address with
+ the command \verb|ifconfig| ... \verb|pointopoint A|.
+
+ {\bf In 2.2} this command has the same semantics on all
+ the interfaces, namely it sets not tunnel endpoint,
+ but address of peering host, which is directly reachable
+ via this tunnel,
+ rather than via Internet. Actual tunnel endpoint address \verb|A|
+ should be set with \verb|ip tunnel add ... remote A|.
+
+\item {\bf In 2.0} you create tunnel routes with the command:
+\begin{verbatim}
+ route add -net 10.0.0.0 gw A dev tunl0
+\end{verbatim}
+
+ {\bf 2.2} interprets this command equally for all device
+ kinds and gateway is required to be directly reachable via this tunnel,
+ rather than via Internet. You still may use \verb|ip route add ... onlink|
+ to override this behaviour.
+
+\end{itemize}
+
+
+\section{Tunnel setup: basics}
+
+Standard Linux-2.2 kernel supports three flavor of tunnels,
+listed in the following table:
+\vspace{2mm}
+
+\begin{tabular}{lll}
+\vrule depth 0.8ex width 0pt\relax
+Mode & Description & Base device \\
+ipip & IP over IP & tunl0 \\
+sit & IPv6 over IP & sit0 \\
+gre & ANY over GRE over IP & gre0
+\end{tabular}
+
+\vspace{2mm}
+
+\noindent All the kinds of tunnels are created with one command:
+\begin{verbatim}
+ ip tunnel add <NAME> mode <MODE> [ local <S> ] [ remote <D> ]
+\end{verbatim}
+
+This command creates new tunnel device with name \verb|<NAME>|.
+The \verb|<NAME>| is an arbitrary string. Particularly,
+it may be even \verb|eth0|. The rest of parameters set
+different tunnel characteristics.
+
+\begin{itemize}
+
+\item
+\verb|mode <MODE>| sets tunnel mode. Three modes are available now
+ \verb|ipip|, \verb|sit| and \verb|gre|.
+
+\item
+\verb|remote <D>| sets remote endpoint of the tunnel to IP
+ address \verb|<D>|.
+\item
+\verb|local <S>| sets fixed local address for tunneled
+ packets. It must be an address on another interface of this host.
+
+\end{itemize}
+
+\let\thefootnote\oldthefootnote
+
+Both \verb|remote| and \verb|local| may be omitted. In this case we
+say that they are zero or wildcard. Two tunnels of one mode cannot
+have the same \verb|remote| and \verb|local|. Particularly it means
+that base device or fallback tunnel cannot be replicated.\footnote{
+This restriction is relaxed for keyed GRE tunnels.}
+
+Tunnels are divided to two classes: {\bf pointopoint} tunnels, which
+have some not wildcard \verb|remote| address and deliver all the packets
+to this destination, and {\bf NBMA} (i.e. Non-Broadcast Multi-Access) tunnels,
+which have no \verb|remote|. Particularly, base devices (f.e.\ \verb|tunl0|)
+are NBMA, because they have neither \verb|remote| nor
+\verb|local| addresses.
+
+
+After tunnel device is created you should configure it as you did
+it with another devices. Certainly, the configuration of tunnels has
+some features related to the fact that they work over existing Internet
+routing infrastructure and simultaneously create new virtual links,
+which changes this infrastructure. The danger that not enough careful
+tunnel setup will result in formation of tunnel loops,
+collapse of routing or flooding network with exponentially
+growing number of tunneled fragments is very real.
+
+
+Protocol setup on pointopoint tunnels does not differ of configuration
+of another devices. You should set a protocol address with \verb|ifconfig|
+and add routes with \verb|route| utility.
+
+NBMA tunnels are different. To route something via NBMA tunnel
+you have to explain to driver, where it should deliver packets to.
+The only way to make it is to create special routes with gateway
+address pointing to desired endpoint. F.e.\
+\begin{verbatim}
+ ip route add 10.0.0.0/24 via <A> dev tunl0 onlink
+\end{verbatim}
+It is important to use option \verb|onlink|, otherwise
+kernel will refuse request to create route via gateway not directly
+reachable over device \verb|tunl0|. With IPv6 the situation is much simpler:
+when you start device \verb|sit0|, it automatically configures itself
+with all IPv4 addresses mapped to IPv6 space, so that all IPv4
+Internet is {\em really reachable} via \verb|sit0|! Excellent, the command
+\begin{verbatim}
+ ip route add 3FFE::/16 via ::193.233.7.65 dev sit0
+\end{verbatim}
+will route \verb|3FFE::/16| via \verb|sit0|, sending all the packets
+destined to this prefix to 193.233.7.65.
+
+\section{Tunnel setup: options}
+
+Command \verb|ip tunnel add| has several additional options.
+\begin{itemize}
+
+\item \verb|ttl N| --- set fixed TTL \verb|N| on tunneled packets.
+ \verb|N| is number in the range 1--255. 0 is special value,
+ meaning that packets inherit TTL value.
+ Default value is: \verb|inherit|.
+
+\item \verb|tos T| --- set fixed tos \verb|T| on tunneled packets.
+ Default value is: \verb|inherit|.
+
+\item \verb|dev DEV| --- bind tunnel to device \verb|DEV|, so that
+ tunneled packets will be routed only via this device and will
+ not be able to escape to another device, when route to endpoint changes.
+
+\item \verb|nopmtudisc| --- disable Path MTU Discovery on this tunnel.
+ It is enabled by default. Note that fixed ttl is incompatible
+ with this option: tunnels with fixed ttl always make pmtu discovery.
+
+\end{itemize}
+
+\verb|ipip| and \verb|sit| tunnels have no more options. \verb|gre|
+tunnels are more complicated:
+
+\begin{itemize}
+
+\item \verb|key K| --- use keyed GRE with key \verb|K|. \verb|K| is
+ either number or IP address-like dotted quad.
+
+\item \verb|csum| --- checksum tunneled packets.
+
+\item \verb|seq| --- serialize packets.
+\begin{NB}
+ I think this option does not
+ work. At least, I did not test it, did not debug it and
+ even do not understand, how it is supposed to work and for what
+ purpose Cisco planned to use it.
+\end{NB}
+
+\end{itemize}
+
+
+Actually, these GRE options can be set separately for input and
+output directions by prefixing corresponding keywords with letter
+\verb|i| or \verb|o|. F.e.\ \verb|icsum| orders to accept only
+packets with correct checksum and \verb|ocsum| means, that
+our host will calculate and send checksum.
+
+Command \verb|ip tunnel add| is not the only operation,
+which can be made with tunnels. Certainly, you may get short help page
+with:
+\begin{verbatim}
+ ip tunnel help
+\end{verbatim}
+
+Besides that, you may view list of installed tunnels with the help of command:
+\begin{verbatim}
+ ip tunnel ls
+\end{verbatim}
+Also you may look at statistics:
+\begin{verbatim}
+ ip -s tunnel ls Cisco
+\end{verbatim}
+where \verb|Cisco| is name of tunnel device. Command
+\begin{verbatim}
+ ip tunnel del Cisco
+\end{verbatim}
+destroys tunnel \verb|Cisco|. And, finally,
+\begin{verbatim}
+ ip tunnel change Cisco mode sit local ME remote HE ttl 32
+\end{verbatim}
+changes its parameters.
+
+\section{Differences 2.2 and 2.0 tunnels revisited.}
+
+Now we can discuss more subtle differences between tunneling in 2.0
+and 2.2.
+
+\begin{itemize}
+
+\item In 2.0 all tunneled packets were received promiscuously
+as soon as you loaded module \verb|ipip|. 2.2 tries to select the best
+tunnel device and packet looks as received on this. F.e.\ if host
+received \verb|ipip| packet from host \verb|D| destined to our
+local address \verb|S|, kernel searches for matching tunnels
+in order:
+
+\begin{tabular}{ll}
+1 & \verb|remote| is \verb|D| and \verb|local| is \verb|S| \\
+2 & \verb|remote| is \verb|D| and \verb|local| is wildcard \\
+3 & \verb|remote| is wildcard and \verb|local| is \verb|S| \\
+4 & \verb|tunl0|
+\end{tabular}
+
+If tunnel exists, but it is not in \verb|UP| state, the tunnel is ignored.
+Note, that if \verb|tunl0| is \verb|UP| it receives all the IPIP packets,
+not acknowledged by more specific tunnels.
+Be careful, it means that without carefully installed firewall rules
+anyone on the Internet may inject to your network any packets with
+source addresses indistinguishable from local ones. It is not so bad idea
+to design tunnels in the way enforcing maximal route symmetry
+and to enable reversed path filter (\verb|rp_filter| sysctl option) on
+tunnel devices.
+
+\item In 2.2 you can monitor and debug tunnels with \verb|tcpdump|.
+F.e.\ \verb|tcpdump| \verb|-i Cisco| \verb|-nvv| will dump packets,
+which kernel output, via tunnel \verb|Cisco| and the packets received on it
+from kernel viewpoint.
+
+\end{itemize}
+
+
+\section{Linux and Cisco IOS tunnels.}
+
+Among another tunnels Cisco IOS supports IPIP and GRE.
+Essentially, Cisco setup is subset of options, available for Linux.
+Let us consider the simplest example:
+
+\begin{verbatim}
+interface Tunnel0
+ tunnel mode gre ip
+ tunnel source 10.10.14.1
+ tunnel destination 10.10.13.2
+\end{verbatim}
+
+
+This command set translates to:
+
+\begin{verbatim}
+ ip tunnel add Tunnel0 \
+ mode gre \
+ local 10.10.14.1 \
+ remote 10.10.13.2
+\end{verbatim}
+
+Any questions? No questions.
+
+\section{Interaction IPIP tunnels and DVMRP.}
+
+DVMRP exploits IPIP tunnels to route multicasts via Internet.
+\verb|mrouted| creates
+IPIP tunnels listed in its configuration file automatically.
+From kernel and user viewpoints there are no differences between
+tunnels, created in this way, and tunnels created by \verb|ip tunnel|.
+I.e.\ if \verb|mrouted| created some tunnel, it may be used to
+route unicast packets, provided appropriate routes are added.
+And vice versa, if administrator has already created a tunnel,
+it will be reused by \verb|mrouted|, if it requests DVMRP
+tunnel with the same local and remote addresses.
+
+Do not wonder, if your manually configured tunnel is
+destroyed, when mrouted exits.
+
+
+\section{Broadcast GRE ``tunnels''.}
+
+It is possible to set \verb|remote| for GRE tunnel to a multicast
+address. Such tunnel becomes {\bf broadcast} tunnel (though word
+tunnel is not quite appropriate in this case, it is rather virtual network).
+\begin{verbatim}
+ ip tunnel add Universe local 193.233.7.65 \
+ remote 224.66.66.66 ttl 16
+ ip addr add 10.0.0.1/16 dev Universe
+ ip link set Universe up
+\end{verbatim}
+This tunnel is true broadcast network and broadcast packets are
+sent to multicast group 224.66.66.66. By default such tunnel starts
+to resolve both IP and IPv6 addresses via ARP/NDISC, so that
+if multicast routing is supported in surrounding network, all GRE nodes
+will find one another automatically and will form virtual Ethernet-like
+broadcast network. If multicast routing does not work, it is unpleasant
+but not fatal flaw. The tunnel becomes NBMA rather than broadcast network.
+You may disable dynamic ARPing by:
+\begin{verbatim}
+ echo 0 > /proc/sys/net/ipv4/neigh/Universe/mcast_solicit
+\end{verbatim}
+and to add required information to ARP tables manually:
+\begin{verbatim}
+ ip neigh add 10.0.0.2 lladdr 128.6.190.2 dev Universe nud permanent
+\end{verbatim}
+In this case packets sent to 10.0.0.2 will be encapsulated in GRE
+and sent to 128.6.190.2. It is possible to facilitate address resolution
+using methods typical for another NBMA networks f.e.\ to start user
+level \verb|arpd| daemon, which will maintain database of hosts attached
+to GRE virtual network or ask for information
+dedicated ARP or NHRP server.
+
+
+Actually, such setup is the most natural for tunneling,
+it is really flexible, scalable and easily managable, so that
+it is strongly recommended to be used with GRE tunnels instead of ugly
+hack with NBMA mode and \verb|onlink| modifier. Unfortunately,
+by historical reasons broadcast mode is not supported by IPIP tunnels,
+but this probably will change in future.
+
+
+
+\section{Traffic control issues.}
+
+Tunnels are devices, hence all the power of Linux traffic control
+applies to them. The simplest (and the most useful in practice)
+example is limiting tunnel bandwidth. The following command:
+\begin{verbatim}
+ tc qdisc add dev tunl0 root tbf \
+ rate 128Kbit burst 4K limit 10K
+\end{verbatim}
+will limit tunneled traffic to 128Kbit with maximal burst size of 4K
+and queuing not more than 10K.
+
+However, you should remember, that tunnels are {\em virtual} devices
+implemented in software and true queue management is impossible for them
+just because they have no queues. Instead, it is better to create classes
+on real physical interfaces and to map tunneled packets to them.
+In general case of dynamic routing you should create such classes
+on all outgoing interfaces, or, alternatively,
+to use option \verb|dev DEV| to bind tunnel to a fixed physical device.
+In the last case packets will be routed only via specified device
+and you need to setup corresponding classes only on it.
+Though you have to pay for this convenience,
+if routing will change, your tunnel will fail.
+
+Suppose that CBQ class \verb|1:ABC| has been created on device \verb|eth0|
+specially for tunnel \verb|Cisco| with endpoints \verb|S| and \verb|D|.
+Now you can select IPIP packets with addresses \verb|S| and \verb|D|
+with some classifier and map them to class \verb|1:ABC|. F.e.\
+it is easy to make with \verb|rsvp| classifier:
+\begin{verbatim}
+ tc filter add dev eth0 pref 100 proto ip rsvp \
+ session D ipproto ipip filter S \
+ classid 1:ABC
+\end{verbatim}
+
+If you want to make more detailed classification of sub-flows
+transmitted via tunnel, you can build CBQ subtree,
+rooted at \verb|1:ABC| and attach to subroot set of rules parsing
+IPIP packets more deeply.

+<title>NSTAT, IFSTAT and RTACCT Utilities
+<author>Alexey Kuznetsov, <tt/kuznet@ms2.inr.ac.ru/
+<date>some_negative_number, 20 Sep 2001
+<abstract>
+<tt/nstat/, <tt/ifstat/ and <tt/rtacct/ are simple tools helping
+to monitor kernel snmp counters and network interface statistics.
+</abstract>
+
+<p> These utilities are very similar, so that I describe
+them simultaneously, using name <tt/Xstat/ in the places which apply
+to all of them.
+
+<p>The format of the command is:
+
+<tscreen><verb>
+ Xstat [ OPTIONS ] [ PATTERN [ PATTERN ... ] ]
+</verb></tscreen>
+
+<p>
+<tt/PATTERN/ is shell style pattern, selecting identifier
+of SNMP variables or interfaces to show. Variable is displayed
+if one of patterns matches its name. If no patterns are given,
+<tt/Xstat/ assumes that user wants to see all the variables.
+
+<p> <tt/OPTIONS/ is list of single letter options, using common unix
+conventions.
+
+<itemize>
+<item><tt/-h/ - show help page
+<item><tt/-?/ - the same, of course
+<item><tt/-v/, <tt/-V/ - print version of <tt/Xstat/ and exit
+<item><tt/-z/ - dump zero counters too. By default they are not shown.
+<item><tt/-a/ - dump absolute values of counters. By default <tt/Xstat/
+ calculates increments since the previous use.
+<item><tt/-s/ - do not update history, so that the next time you will
+ see counters including values accumulated to the moment
+ of this measurement too.
+<item><tt/-n/ - do not display anything, only update history.
+<item><tt/-r/ - reset history.
+<item><tt/-d INTERVAL/ - <tt/Xstat/ is run in daemon mode collecting
+ statistics. <tt/INTERVAL/ is interval between measurements
+ in seconds.
+<item><tt/-t INTERVAL/ - time interval to average rates. Default value
+ is 60 seconds.
+<item><tt/-e/ - display extended information about errors (<tt/ifstat/ only).
+</itemize>
+
+<p>
+History is just dump saved in file <tt>/tmp/.Xstat.uUID</tt>
+or in file given by environment variables <tt/NSTAT_HISTORY/,
+<tt/IFSTAT_HISTORY/ and <tt/RTACCT_HISTORY/.
+Each time when you use <tt/Xstat/ values there are updated.
+If you use patterns, only the values which you _really_ see
+are updated. If you want to skip an unintersting period,
+use option <tt/-n/, or just output to <tt>/dev/null</tt>.
+
+<p>
+<tt/Xstat/ understands when history is invalidated by system reboot
+or source of information switched between different instances
+of daemonic <tt/Xstat/ and kernel SNMP tables and does not
+use invalid history.
+
+<p> Beware, <tt/Xstat/ will not produce sane output,
+when many processes use it simultaneously. If several processes
+under single user need this utility they should use environment
+variables to put their history in safe places
+or to use it with options <tt/-a -s/.
+
+<p>
+Well, that's all. The utility is very simple, but nevertheless
+very handy.
+
+<p> <bf/Output of XSTAT/
+<p> The first line of output is <tt/#/ followed by identifier
+of source of information, it may be word <tt/kernel/, when <tt/Xstat/
+gets information from kernel or some dotted decimal number followed
+by parameters, when it obtains information from running <tt/Xstat/ daemon.
+
+<p>In the case of <tt/nstat/ the rest of output consists of three columns:
+SNMP MIB identifier,
+its value (or increment since previous measurement) and average
+rate of increase of the counter per second. <tt/ifstat/ outputs
+interface name followed by pairs of counter and rate of its change.
+
+<p> <bf/Daemonic Xstat/
+<p> <tt/Xstat/ may be started as daemon by any user. This makes sense
+to avoid wrapped counters and to obtain reasonable long counters
+for large time. Also <tt/Xstat/ daemon calculates average rates.
+For the first goal sampling interval (option <tt/-d/) may be large enough,
+f.e. for gigabit rates byte counters overflow not more frequently than
+each 40 seconds and you may select interval of 20 seconds.
+From the other hand, when <tt/Xstat/ is used for estimating rates
+interval should be less than averaging period (option <tt/-t/), otherwise
+estimation loses in quality.
+
+Client <tt/Xstat/, before trying to get information from the kernel,
+contacts daemon started by this user, then it tries system wide
+daemon, which is supposed to be started by superuser. And only if
+none of them replied it gets information from kernel.
+
+<p> <bf/Environment/
+<p> <tt/NSTAT_HISTORY/ - name of history file for <tt/nstat/.
+<p> <tt/IFSTAT_HISTORY/ - name of history file for <tt/ifstat/.
+<p> <tt/RTACCT_HISTORY/ - name of history file for <tt/rtacct/.

+
+<p>
+Here is some code for monitoring the route cache. For systems handling high
+network load, servers, routers, firewalls etc the route cache and its garbage
+collection is crucial. Linux has a solid implementation.
+
+<p>
+The kernel patch (not required since linux-2.4.7) adds statistics counters

+<title>SS Utility: Quick Intro
+<author>Alexey Kuznetsov, <tt/kuznet@ms2.inr.ac.ru/
+<date>some_negative_number, 20 Sep 2001
+<abstract>
+<tt/ss/ is one another utility to investigate sockets.
+Functionally it is NOT better than <tt/netstat/ combined
+with some perl/awk scripts and though it is surely faster
+it is not enough to make it much better. :-)
+So, stop reading this now and do not waste your time.
+Well, certainly, it proposes some functionality, which current
+netstat is still not able to do, but surely will soon.
+</abstract>
+
+<sect>Why?
+
+<p> <tt>/proc</tt> interface is inadequate, unfortunately.
+When amount of sockets is enough large, <tt/netstat/ or even
+plain <tt>cat /proc/net/tcp/</tt> cause nothing but pains and curses.
+In linux-2.4 the desease became worse: even if amount
+of sockets is small reading <tt>/proc/net/tcp/</tt> is slow enough.
+
+This utility presents a new approach, which is supposed to scale
+well. I am not going to describe technical details here and
+will concentrate on description of the command.
+The only important thing to say is that it is not so bad idea
+to load module <tt/tcp_diag/, which can be found in directory
+<tt/Modules/ of <tt/iproute2/. If you do not make this <tt/ss/
+will work, but it falls back to <tt>/proc</tt> and becomes slow
+like <tt/netstat/, well, a bit faster yet (see section "Some numbers").
+
+<sect>Old news
+
+<p>
+In the simplest form <tt/ss/ is equivalent to netstat
+with some small deviations.
+
+<itemize>
+<item><tt/ss -t -a/ dumps all TCP sockets
+<item><tt/ss -u -a/ dumps all UDP sockets
+<item><tt/ss -w -a/ dumps all RAW sockets
+<item><tt/ss -x -a/ dumps all UNIX sockets
+</itemize>
+
+<p>
+Option <tt/-o/ shows TCP timers state.
+Option <tt/-e/ shows some extended information.
+Etc. etc. etc. Seems, all the options of netstat related to sockets
+are supported. Though not AX.25 and other bizarres. :-)
+If someone wants, he can make support for decnet and ipx.
+Some rudimentary support for them is already present in iproute2 libutils,
+and I will be glad to see these new members.
+
+<p>
+However, standard functionality is a bit different:
+
+<p>
+The first: without option <tt/-a/ sockets in states
+<tt/TIME-WAIT/ and <tt/SYN-RECV/ are skipped too.
+It is more reasonable default, I think.
+
+<p>
+The second: format of UNIX sockets is different. It coincides
+with tcp/udp. Though standard kernel still does not allow to
+see write/read queues and peer address of connected UNIX sockets,
+the patch doing this exists.
+
+<p>
+The third: default is to dump only TCP sockets, rather than all of the types.
+
+<p>
+The next: by default it does not resolve numeric host addresses (like <tt/ip/)!
+Resolving is enabled with option <tt/-r/. Service names, usually stored
+in local files, are resolved by default. Also, if service database
+does not contain references to a port, <tt/ss/ queries system
+<tt/rpcbind/. RPC services are prefixed with <tt/rpc./
+Resolution of services may be suppressed with option <tt/-n/.
+
+<p>
+It does not accept "long" options (I dislike them, sorry).
+So, address family is given with family identifier following
+option <tt/-f/ to be algined to iproute2 conventions.
+Mostly, it is to allow option parser to parse
+addresses correctly, but as side effect it really limits dumping
+to sockets supporting only given family. Option <tt/-A/ followed
+by list of socket tables to dump is also supported.
+Logically, id of socket table is different of _address_ family, which is
+another point of incompatibility. So, id is one of
+<tt/all/, <tt/tcp/, <tt/udp/,
+<tt/raw/, <tt/inet/, <tt/unix/, <tt/packet/, <tt/netlink/. See?
+Well, <tt/inet/ is just abbreviation for <tt/tcp|udp|raw/
+and it is not difficult to guess that <tt/packet/ allows
+to look at packet sockets. Actually, there are also some other abbreviations,
+f.e. <tt/unix_dgram/ selects only datagram UNIX sockets.
+
+<p>
+The next: well, I still do not know. :-)
+
+
+
+
+<sect>Time to talk about new functionality.
+
+<p>It is builtin filtering of socket lists.
+
+<sect1> Filtering by state.
+
+<p>
+<tt/ss/ allows to filter socket states, using keywords
+<tt/state/ and <tt/exclude/, followed by some state
+identifier.
+
+<p>
+State identifier are standard TCP state names (not listed,
+they are useless for you if you already do not know them)
+or abbreviations:
+
+<itemize>
+<item><tt/all/ - for all the states
+<item><tt/bucket/ - for TCP minisockets (<tt/TIME-WAIT|SYN-RECV/)
+<item><tt/big/ - all except for minisockets
+<item><tt/connected/ - not closed and not listening
+<item><tt/synchronized/ - connected and not <tt/SYN-SENT/
+</itemize>
+
+<p>
+ F.e. to dump all tcp sockets except <tt/SYN-RECV/:
+
+<tscreen><verb>
+ ss exclude SYN-RECV
+</verb></tscreen>
+
+<p>
+ If neither <tt/state/ nor <tt/exclude/ directives
+ are present,
+ state filter defaults to <tt/all/ with option <tt/-a/
+ or to <tt/all/,
+ excluding listening, syn-recv, time-wait and closed sockets.
+
+<sect1> Filtering by addresses and ports.
+
+<p>
+Option list may contain address/port filter.
+It is boolean expression which consists of boolean operation
+<tt/or/, <tt/and/, <tt/not/ and predicates.
+Actually, all the flavors of names for boolean operations are eaten:
+<tt/&/, <tt/&&/, <tt/|/, <tt/||/, <tt/!/, but do not forget
+about special sense given to these symbols by unix shells and escape
+them correctly, when used from command line.
+
+<p>
+Predicates may be of the folowing kinds:
+
+<itemize>
+<item>A. Address/port match, where address is checked against mask
+ and port is either wildcard or exact. It is one of:
+
+<tscreen><verb>
+ dst prefix:port
+ src prefix:port
+ src unix:STRING
+ src link:protocol:ifindex
+ src nl:channel:pid
+</verb></tscreen>
+
+ Both prefix and port may be absent or replaced with <tt/*/,
+ which means wildcard. UNIX socket use more powerful scheme
+ matching to socket names by shell wildcards. Also, prefixes
+ unix: and link: may be omitted, if address family is evident
+ from context (with option <tt/-x/ or with <tt/-f unix/
+ or with <tt/unix/ keyword)
+
+<p>
+ F.e.
+
+<tscreen><verb>
+ dst 10.0.0.1
+ dst 10.0.0.1:
+ dst 10.0.0.1/32:
+ dst 10.0.0.1:*
+</verb></tscreen>
+ are equivalent and mean socket connected to
+ any port on host 10.0.0.1
+
+<tscreen><verb>
+ dst 10.0.0.0/24:22
+</verb></tscreen>
+ sockets connected to port 22 on network
+ 10.0.0.0...255.
+
+<p>
+ Note that port separated of address with colon, which creates
+ troubles with IPv6 addresses. Generally, we interpret the last
+ colon as splitting port. To allow to give IPv6 addresses,
+ trick like used in IPv6 HTTP URLs may be used:
+
+<tscreen><verb>
+ dst [::1]
+</verb></tscreen>
+ are sockets connected to ::1 on any port
+
+<p>
+ Another way is <tt/dst ::1/128/. / helps to understand that
+ colon is part of IPv6 address.
+
+<p>
+ Now we can add another alias for <tt/dst 10.0.0.1/:
+ <tt/dst [10.0.0.1]/. :-)
+
+<p> Address may be a DNS name. In this case all the addresses are looked
+ up (in all the address families, if it is not limited by option <tt/-f/
+ or special address prefix <tt/inet:/, <tt/inet6/) and resulting
+ expression is <tt/or/ over all of them.
+
+<item> B. Port expressions:
+<tscreen><verb>
+ dport >= :1024
+ dport != :22
+ sport < :32000
+</verb></tscreen>
+ etc.
+
+ All the relations: <tt/</, <tt/>/, <tt/=/, <tt/>=/, <tt/=/, <tt/==/,
+ <tt/!=/, <tt/eq/, <tt/ge/, <tt/lt/, <tt/ne/...
+ Use variant which you like more, but not forget to escape special
+ characters when typing them in command line. :-)
+
+ Note that port number syntactically coincides to the case A!
+ You may even add an IP address, but it will not participate
+ incomparison, except for <tt/==/ and <tt/!=/, which are equivalent
+ to corresponding predicates of type A. F.e.
+<p>
+<tt/dst 10.0.0.1:22/
+ is equivalent to <tt/dport eq 10.0.0.1:22/
+ and
+ <tt/not dst 10.0.0.1:22/ is equivalent to
+ <tt/dport neq 10.0.0.1:22/
+
+<item>C. Keyword <tt/autobound/. It matches to sockets bound automatically
+ on local system.
+
+</itemize>
+
+
+<sect> Examples
+
+<p>
+<itemize>
+<item>1. List all the tcp sockets in state <tt/FIN-WAIT-1/ for our apache
+ to network 193.233.7/24 and look at their timers:
+
+<tscreen><verb>
+ ss -o state fin-wait-1 \( sport = :http or sport = :https \) \
+ dst 193.233.7/24
+</verb></tscreen>
+
+ Oops, forgot to say that missing logical operation is
+ equivalent to <tt/and/.
+
+<item> 2. Well, now look at the rest...
+
+<tscreen><verb>
+ ss -o excl fin-wait-1
+ ss state fin-wait-1 \( sport neq :http and sport neq :https \) \
+ or not dst 193.233.7/24
+</verb></tscreen>
+
+ Note that we have to do _two_ calls of ss to do this.
+ State match is always anded to address/port match.
+ The reason for this is purely technical: ss does fast skip of
+ not matching states before parsing addresses and I consider the
+ ability to skip fastly gobs of time-wait and syn-recv sockets
+ as more important than logical generality.
+
+<item> 3. So, let's look at all our sockets using autobound ports:
+
+<tscreen><verb>
+ ss -a -A all autobound
+</verb></tscreen>
+
+
+<item> 4. And eventually find all the local processes connected
+ to local X servers:
+
+<tscreen><verb>
+ ss -xp dst "/tmp/.X11-unix/*"
+</verb></tscreen>
+
+ Pardon, this does not work with current kernel, patching is required.
+ But we still can look at server side:
+
+<tscreen><verb>
+ ss -x src "/tmp/.X11-unix/*"
+</verb></tscreen>
+
+</itemize>
+
+
+<sect> Returning to ground: real manual
+
+<p>
+<sect1> Command arguments
+
+<p> General format of arguments to <tt/ss/ is:
+
+<tscreen><verb>
+ ss [ OPTIONS ] [ STATE-FILTER ] [ ADDRESS-FILTER ]
+</verb></tscreen>
+
+<sect2><tt/OPTIONS/
+<p> <tt/OPTIONS/ is list of single letter options, using common unix
+conventions.
+
+<itemize>
+<item><tt/-h/ - show help page
+<item><tt/-?/ - the same, of course
+<item><tt/-v/, <tt/-V/ - print version of <tt/ss/ and exit
+<item><tt/-s/ - print summary statistics. This option does not parse
+socket lists obtaining summary from various sources. It is useful
+when amount of sockets is so huge that parsing <tt>/proc/net/tcp</tt>
+is painful.
+<item><tt/-D FILE/ - do not display anything, just dump raw information
+about TCP sockets to <tt/FILE/ after applying filters. If <tt/FILE/ is <tt/-/
+<tt/stdout/ is used.
+<item><tt/-F FILE/ - read continuation of filter from <tt/FILE/.
+Each line of <tt/FILE/ is interpreted like single command line option.
+If <tt/FILE/ is <tt/-/ <tt/stdin/ is used.
+<item><tt/-r/ - try to resolve numeric address/ports
+<item><tt/-n/ - do not try to resolve ports
+<item><tt/-o/ - show some optional information, f.e. TCP timers
+<item><tt/-i/ - show some infomration specific to TCP (RTO, congestion
+window, slow start threshould etc.)
+<item><tt/-e/ - show even more optional information
+<item><tt/-m/ - show extended information on memory used by the socket.
+It is available only with <tt/tcp_diag/ enabled.
+<item><tt/-p/ - show list of processes owning the socket
+<item><tt/-f FAMILY/ - default address family used for parsing addresses.
+ Also this option limits listing to sockets supporting
+ given address family. Currently the following families
+ are supported: <tt/unix/, <tt/inet/, <tt/inet6/, <tt/link/,
+ <tt/netlink/.
+<item><tt/-4/ - alias for <tt/-f inet/
+<item><tt/-6/ - alias for <tt/-f inet6/
+<item><tt/-0/ - alias for <tt/-f link/
+<item><tt/-A LIST-OF-TABLES/ - list of socket tables to dump, separated
+ by commas. The following identifiers are understood:
+ <tt/all/, <tt/inet/, <tt/tcp/, <tt/udp/, <tt/raw/,
+ <tt/unix/, <tt/packet/, <tt/netlink/, <tt/unix_dgram/,
+ <tt/unix_stream/, <tt/packet_raw/, <tt/packet_dgram/.
+<item><tt/-x/ - alias for <tt/-A unix/
+<item><tt/-t/ - alias for <tt/-A tcp/
+<item><tt/-u/ - alias for <tt/-A udp/
+<item><tt/-w/ - alias for <tt/-A raw/
+<item><tt/-a/ - show sockets of all the states. By default sockets
+ in states <tt/LISTEN/, <tt/TIME-WAIT/, <tt/SYN_RECV/
+ and <tt/CLOSE/ are skipped.
+<item><tt/-l/ - show only sockets in state <tt/LISTEN/
+</itemize>
+
+<sect2><tt/STATE-FILTER/
+
+<p><tt/STATE-FILTER/ allows to construct arbitrary set of
+states to match. Its syntax is sequence of keywords <tt/state/
+and <tt/exclude/ followed by identifier of state.
+Available identifiers are:
+
+<p>
+<itemize>
+<item> All standard TCP states: <tt/established/, <tt/syn-sent/,
+<tt/syn-recv/, <tt/fin-wait-1/, <tt/fin-wait-2/, <tt/time-wait/,
+<tt/closed/, <tt/close-wait/, <tt/last-ack/, <tt/listen/ and <tt/closing/.
+
+<item><tt/all/ - for all the states
+<item><tt/connected/ - all the states except for <tt/listen/ and <tt/closed/
+<item><tt/synchronized/ - all the <tt/connected/ states except for
+<tt/syn-sent/
+<item><tt/bucket/ - states, which are maintained as minisockets, i.e.
+<tt/time-wait/ and <tt/syn-recv/.
+<item><tt/big/ - opposite to <tt/bucket/
+</itemize>
+
+<sect2><tt/ADDRESS_FILTER/
+
+<p><tt/ADDRESS_FILTER/ is boolean expression with operations <tt/and/, <tt/or/
+and <tt/not/, which can be abbreviated in C style f.e. as <tt/&/,
+<tt/&&/.
+
+<p>
+Predicates check socket addresses, both local and remote.
+There are the following kinds of predicates:
+
+<itemize>
+<item> <tt/dst ADDRESS_PATTERN/ - matches remote address and port
+<item> <tt/src ADDRESS_PATTERN/ - matches local address and port
+<item> <tt/dport RELOP PORT/ - compares remote port to a number
+<item> <tt/sport RELOP PORT/ - compares local port to a number
+<item> <tt/autobound/ - checks that socket is bound to an ephemeral
+ port
+</itemize>
+
+<p><tt/RELOP/ is some of <tt/<=/, <tt/>=/, <tt/==/ etc.
+To make this more convinient for use in unix shell, alphabetic
+FORTRAN-like notations <tt/le/, <tt/gt/ etc. are accepted as well.
+
+<p>The format and semantics of <tt/ADDRESS_PATTERN/ depends on address
+family.
+
+<itemize>
+<item><tt/inet/ - <tt/ADDRESS_PATTERN/ consists of IP prefix, optionally
+followed by colon and port. If prefix or port part is absent or replaced
+with <tt/*/, this means wildcard match.
+<item><tt/inet6/ - The same as <tt/inet/, only prefix refers to an IPv6
+address. Unlike <tt/inet/ colon becomes ambiguous, so that <tt/ss/ allows
+to use scheme, like used in URLs, where address is suppounded with
+<tt/[/ ... <tt/]/.
+<item><tt/unix/ - <tt/ADDRESS_PATTERN/ is shell-style wildcard.
+<item><tt/packet/ - format looks like <tt/inet/, only interface index
+stays instead of port and link layer protocol id instead of address.
+<item><tt/netlink/ - format looks like <tt/inet/, only socket pid
+stays instead of port and netlink channel instead of address.
+</itemize>
+
+<p><tt/PORT/ is syntactically <tt/ADDRESS_PATTERN/ with wildcard
+address part. Certainly, it is undefined for UNIX sockets.
+
+<sect1> Environment variables
+
+<p>
+<tt/ss/ allows to change source of information using various
+environment variables:
+
+<p>
+<itemize>
+<item> <tt/PROC_SLABINFO/ to override <tt>/proc/slabinfo</tt>
+<item> <tt/PROC_NET_TCP/ to override <tt>/proc/net/tcp</tt>
+<item> <tt/PROC_NET_UDP/ to override <tt>/proc/net/udp</tt>
+<item> etc.
+</itemize>
+
+<p>
+Variable <tt/PROC_ROOT/ allows to change root of all the <tt>/proc/</tt>
+hierarchy.
+
+<p>
+Variable <tt/TCPDIAG_FILE/ prescribes to open a file instead of
+requesting kernel to dump information about TCP sockets.
+
+
+<p> This option is used mainly to investigate bug reports,
+when dumps of files usually found in <tt>/proc/</tt> are recevied
+by e-mail.
+
+<sect1> Output format
+
+<p>Six columns. The first is <tt/Netid/, it denotes socket type and
+transport protocol, when it is ambiguous: <tt/tcp/, <tt/udp/, <tt/raw/,
+<tt/u_str/ is abbreviation for <tt/unix_stream/, <tt/u_dgr/ for UNIX
+datagram sockets, <tt/nl/ for netlink, <tt/p_raw/ and <tt/p_dgr/ for
+raw and datagram packet sockets. This column is optional, it will
+be hidden, if filter selects an unique netid.
+
+<p>
+The second column is <tt/State/. Socket state is displayed here.
+The names are standard TCP names, except for <tt/UNCONN/, which
+cannot happen for TCP, but normal for not connected sockets
+of another types. Again, this column can be hidden.
+
+<p>
+Then two columns (<tt/Recv-Q/ and <tt/Send-Q/) showing amount of data
+queued for receive and transmit.
+
+<p>
+And the last two columns display local address and port of the socket
+and its peer address, if the socket is connected.
+
+<p>
+If options <tt/-o/, <tt/-e/ or <tt/-p/ were given, options are
+displayed not in fixed positions but separated by spaces pairs:
+<tt/option:value/. If value is not a single number, it is presented
+as list of values, enclosed to <tt/(/ ... <tt/)/ and separated with
+commas. F.e.
+
+<tscreen><verb>
+ timer:(keepalive,111min,0)
+</verb></tscreen>
+is typical format for TCP timer (option <tt/-o/).
+
+<tscreen><verb>
+ users:((X,113,3))
+</verb></tscreen>
+is typical for list of users (option <tt/-p/).
+
+
+<sect>Some numbers
+
+<p>
+Well, let us use <tt/pidentd/ and a tool <tt/ibench/ to measure
+its performance. It is 30 requests per second here. Nothing to test,
+it is too slow. OK, let us patch pidentd with patch from directory
+Patches. After this it handles about 4300 requests per second
+and becomes handy tool to pollute socket tables with lots of timewait
+buckets.
+
+<p>
+So, each test starts from pollution tables with 30000 sockets
+and then doing full dump of the table piped to wc and measuring
+timings with time:
+
+<p>Results:
+
+<itemize>
+<item> <tt/netstat -at/ - 15.6 seconds
+<item> <tt/ss -atr/, but without <tt/tcp_diag/ - 5.4 seconds
+<item> <tt/ss -atr/ with <tt/tcp_diag/ - 0.47 seconds
+</itemize>
+
+No comments. Though one comment is necessary, most of time
+without <tt/tcp_diag/ is wasted inside kernel with completely
+blocked networking. More than 10 seconds, yes. <tt/tcp_diag/
+does the same work for 100 milliseconds of system time.

+# CHANGES
+# -------
+# v0.3a2- fixed bug in "if" operator. Thanks kad@dgtu.donetsk.ua.
+# v0.3a- added TIME parameter. Example:
+# TIME=00:00-19:00;64Kbit/6Kbit
+# So, between 00:00 and 19:00 RATE will be 64Kbit.
+# Just start "cbq.init timecheck" periodically from cron (every 10
+# minutes for example).
+# !!! Anyway you MUST start "cbq.init start" for CBQ initialize.
+# v0.2 - Some cosmetique changes. Now it more compatible with
+# old bash version. Thanks to Stanislav V. Voronyi
+# <stas@cnti.uanet.kharkov.ua>.
+# v0.1 - First public release
+#
+# README
+# ------
+#
+# First of all - this is just a SIMPLE EXAMPLE of CBQ power.
+# Don't ask me "why" and "how" :)
+#
+# This is an example of using CBQ (Class Based Queueing) and policy-based
+# filter for building smart ethernet shapers. All CBQ parameters are
+# correct only for ETHERNET (eth0,1,2..) linux interfaces. It works for
+# ARCNET too (just set bandwidth parameter to 2Mbit). It was tested
+# on 2.1.125-2.1.129 linux kernels (KSI linux, Nostromo version) and
+# ip-route utility by A.Kuznetsov (iproute2-ss981101 version).
+# You can download ip-route from ftp://ftp.inr.ac.ru/ip-routing or
+# get iproute2*.rpm (compiled with glibc) from ftp.ksi-linux.com.
+#
+#
+# HOW IT WORKS
+#
+# Each shaper must be described by config file in $CBQ_PATH
+# (/etc/sysconfig/cbq/) directory - one config file for each CBQ shaper.
+#
+# Some words about config file name:
+# Each shaper has its personal ID - two byte HEX number. Really ID is
+# CBQ class.
+# So, filename looks like:
+#
+# cbq-1280.My_first_shaper
+# ^^^ ^^^ ^^^^^^^^^^^^^
+# | | |______ Shaper name - any word
+# | |___________________ ID (0000-FFFF), let ID looks like shaper's rate
+# |______________________ Filename must begin from "cbq-"
+#
+#
+# Config file describes shaper parameters and source[destination]
+# address[port].
+# For example let's prepare /etc/sysconfig/cbq/cbq-1280.My_first_shaper:
+#
+# ----------8<---------------------
+# DEVICE=eth0,10Mbit,1Mbit
+# RATE=128Kbit
+# WEIGHT=10Kbit
+# PRIO=5
+# RULE=192.168.1.0/24
+# ----------8<---------------------
+#
+# This is minimal configuration, where:
+# DEVICE: eth0 - device where we do control our traffic
+# 10Mbit - REAL ethernet card bandwidth
+# 1Mbit - "weight" of :1 class (parent for all shapers for eth0),
+# as a rule of thumb weight=batdwidth/10.
+# 100Mbit adapter's example: DEVICE=eth0,100Mbit,10Mbit
+# *** If you want to build more than one shaper per device it's
+# enough to describe bandwidth and weight once - cbq.init
+# is smart :) You can put only 'DEVICE=eth0' into cbq-*
+# config file for eth0.
+#
+# RATE: Shaper's speed - Kbit,Mbit or bps (bytes per second)
+#
+# WEIGHT: "weight" of shaper (CBQ class). Like for DEVICE - approx. RATE/10
+#
+# PRIO: shaper's priority from 1 to 8 where 1 is the highest one.
+# I do always use "5" for all my shapers.
+#
+# RULE: [source addr][:source port],[dest addr][:dest port]
+# Some examples:
+# RULE=10.1.1.0/24:80 - all traffic for network 10.1.1.0 to port 80
+# will be shaped.
+# RULE=10.2.2.5 - shaper works only for IP address 10.2.2.5
+# RULE=:25,10.2.2.128/25:5000 - all traffic from any address and port 25 to
+# address 10.2.2.128 - 10.2.2.255 and port 5000
+# will be shaped.
+# RULE=10.5.5.5:80, - shaper active only for traffic from port 80 of
+# address 10.5.5.5
+# Multiple RULE fields per one config file are allowed. For example:
+# RULE=10.1.1.2:80
+# RULE=10.1.1.2:25
+# RULE=10.1.1.2:110
+#
+# *** ATTENTION!!!
+# All shapers do work only for outgoing traffic!
+# So, if you want to build bidirectional shaper you must set it up for
+# both ethernet card. For example let's build shaper for our linux box like:
+#
+# --------- 192.168.1.1
+# BACKBONE -----eth0-| linux |-eth1------*[our client]
+# ---------
+#
+# Let all traffic from backbone to client will be shaped at 28Kbit and
+# traffic from client to backbone - at 128Kbit. We need two config files:
+#
+# ---8<-----/etc/sysconfig/cbq/cbq-28.client-out----
+# DEVICE=eth1,10Mbit,1Mbit
+# RATE=28Kbit
+# WEIGHT=2Kbit
+# PRIO=5
+# RULE=192.168.1.1
+# ---8<---------------------------------------------
+#
+# ---8<-----/etc/sysconfig/cbq/cbq-128.client-in----
+# DEVICE=eth0,10Mbit,1Mbit
+# RATE=128Kbit
+# WEIGHT=10Kbit
+# PRIO=5
+# RULE=192.168.1.1,
+# ---8<---------------------------------------------
+# ^pay attention to "," - this is source address!
+#
+# Enjoy.

+/*
+ * eBPF user space agent part
+ *
+ * Simple, _self-contained_ user space agent for the eBPF kernel
+ * ebpf_prog.c program, which gets all map fds passed from tc via unix
+ * domain socket in one transaction and can thus keep referencing
+ * them from user space in order to read out (or possibly modify)
+ * map data. Here, just as a minimal example to display counters.
+ *
+ * The agent only uses the bpf(2) syscall API to read or possibly
+ * write to eBPF maps, it doesn't need to be aware of the low-level
+ * bytecode parts and/or ELF parsing bits.
+ *
+ * ! For more details, see header comment in bpf_prog.c !
+ *
+ * gcc bpf_agent.c -o bpf_agent -Wall -O2
+ *
+ * For example, a more complex user space agent could run on each
+ * host, reading and writing into eBPF maps used by tc classifier
+ * and actions. It would thus allow for implementing a distributed
+ * tc architecture, for example, which would push down central
+ * policies into eBPF maps, and thus altering run-time behaviour.
+ *
+ * -- Happy eBPF hacking! ;)

+ * eBPF kernel space program part
+ *
+ * Toy eBPF program for demonstration purposes, some parts derived from
+ * kernel tree's samples/bpf/sockex2_kern.c example.
+ *
+ * More background on eBPF, kernel tree: Documentation/networking/filter.txt
+ *
+ * Note, this file is rather large, and most classifier and actions are
+ * likely smaller to accomplish one specific use-case and are tailored
+ * for high performance. For performance reasons, you might also have the
+ * classifier and action already merged inside the classifier.
+ *
+ * In order to show various features it serves as a bigger programming
+ * example, which you should feel free to rip apart and experiment with.
+ *
+ * Compilation, configuration example:
+ *
+ * Note: as long as the BPF backend in LLVM is still experimental,
+ * you need to build LLVM with LLVM with --enable-experimental-targets=BPF
+ * Also, make sure your 4.1+ kernel is compiled with CONFIG_BPF_SYSCALL=y,
+ * and you have libelf.h and gelf.h headers and can link tc against -lelf.
+ *
+ * In case you need to sync kernel headers, go to your kernel source tree:
+ * # make headers_install INSTALL_HDR_PATH=/usr/
+ *
+ * $ export PATH=/home/<...>/llvm/Debug+Asserts/bin/:$PATH
+ * $ clang -O2 -emit-llvm -c bpf_prog.c -o - | llc -march=bpf -filetype=obj -o bpf.o

+ * # tc qdisc add dev em1 handle ffff: ingress
+ * # tc filter add dev em1 parent ffff: bpf obj ...
+ *
+ * Notes on BPF agent:
+ *
+ * In the above example, the bpf_agent creates the unix domain socket
+ * natively. "tc exec" can also spawn a shell and hold the socktes there:
+ *
+ * # tc exec bpf imp /tmp/bpf-uds
+ * # tc filter add dev em1 parent 1: bpf obj bpf.o exp /tmp/bpf-uds flowid 1:1 \
+ * action bpf obj bpf.o sec action-mark \
+ * action bpf obj bpf.o sec action-rand ok
+ * sh-4.2# (shell spawned from tc exec)
+ * sh-4.2# bpf_agent
+ * [...]
+ *
+ * This will read out fds over environment and produce the same data dump
+ * as below. This has the advantage that the spawned shell owns the fds
+ * and thus if the agent is restarted, it can reattach to the same fds, also
+ * various programs can easily read/modify the data simultaneously from user
+ * space side.
+ *
+ * If the shell is unnecessary, the agent can also just be spawned directly
+ * via tc exec:
+ *
+ * # tc exec bpf imp /tmp/bpf-uds run bpf_agent
+ * # tc filter add dev em1 parent 1: bpf obj bpf.o exp /tmp/bpf-uds flowid 1:1 \
+ * action bpf obj bpf.o sec action-mark \

+ * This now means, the below classifier and action pipeline has been loaded
+ * as eBPF bytecode into the kernel, the kernel has verified that the
+ * execution of the bytecode is "safe", and it has JITed the programs
+ * afterwards, so that upon invocation they're running on native speed. tc
+ * has transferred all map file descriptors to the bpf_agent via IPC and
+ * even after tc exits, the agent can read out or modify all map data.
+ *
+ * Note that the export to the uds is done only once in the classifier and
+ * not in the action. It's enough to export the (here) shared descriptors
+ * once.
+ *
+ * If you need to disassemble the generated JIT image (echo with 2), the
+ * kernel tree has under tools/net/ a small helper, you can invoke e.g.
+ * `bpf_jit_disasm -o`.
+ *
+ * Please find in the code below further comments.

+# VERSION HISTORY
+# ---------------
+# v0.7.3- Deepak Singhal <singhal at users.sourceforge.net>
+# - fix timecheck to not ignore regular TIME rules after
+# encountering a TIME rule that spans over midnight
+# - Nathan Shafer <nicodemus at users.sourceforge.net>
+# - allow symlinks to class files
+# - Seth J. Blank <antifreeze at users.sourceforge.net>
+# - replace hardcoded ip/tc location with variables
+# - Mark Davis <mark.davis at gmx.de>
+# - allow setting of PRIO_{MARK,RULE,REALM} in class file
+# - Fernando Sanch <toptnc at users.sourceforge.net>
+# - allow underscores in interface names
+# v0.7.2- Paulo Sedrez
+# - fix time2abs to allow hours with leading zero in TIME rules
+# - Svetlin Simeonov <zvero at yahoo.com>
+# - fix cbq_device_list to allow VLAN interfaces
+# - Mark Davis <mark.davis at gmx.de>
+# - ignore *~ backup files when looking for classes
+# - Mike Boyer <boyer at administrative.com>
+# - fix to allow arguments to be passed to "restart" command
+# v0.7.1- Lubomir Bulej <pallas at kadan.cz>
+# - default value for PERTURB
+# - fixed small bug in RULE parser to correctly parse rules with
+# identical source and destination fields
+# - faster initial scanning of DEVICE fields
+# v0.7 - Lubomir Bulej <pallas at kadan.cz>
+# - lots of various cleanups and reorganizations; the parsing is now
+# some 40% faster, but the class ID must be in range 0x0002-0xffff
+# (again). Because of the number of internal changes and the above
+# class ID restriction, I bumped the version to 0.7 to indicate
+# something might have got broken :)
+# - changed PRIO_{U32,FW,ROUTE} to PRIO_{RULE,MARK,REALM}
+# for consistency with filter keywords
+# - exposed "compile" command
+# - Catalin Petrescu <taz at dntis.ro>
+# - support for port masks in RULE (u32) filter
+# - Jordan Vrtanoski <obeliks at mt.net.mk>
+# - support for week days in TIME rules
+# v0.6.4- Lubomir Bulej <pallas at kadan.cz>
+# - added PRIO_* variables to allow easy control of filter priorities
+# - added caching to speed up CBQ start, the cache is invalidated
+# whenever any of the configuration files changes
+# - updated the readme section + some cosmetic fixes
+# v0.6.3- Lubomir Bulej <pallas at kadan.cz>
+# - removed setup of (unnecessary) class 1:1 - all classes
+# now use qdisc's default class 1:0 as their parent
+# - minor fix in the timecheck branch - classes
+# without leaf qdisc were not updated
+# - minor fix to avoid timecheck failure when run
+# at time with minutes equal to 08 or 09
+# - respect CBQ_PATH setting in environment
+# - made PRIO=5 default, rendering it optional in configs
+# - added support for route filter, see notes about REALM keyword
+# - added support for fw filter, see notes about MARK keyword
+# - added filter display to "list" and "stats" commands
+# - readme section update + various cosmetic fixes
+# v0.6.2- Catalin Petrescu <taz at dntis.ro>
+# - added tunnels interface handling
+# v0.6.1- Pavel Golubev <pg at ksi-linux.com>
+# - added sch_prio module loading
+# (thanks johan at iglo.virtual.or.id for reminding)
+# - resolved errors resulting from stricter syntax checking in bash2
+# - Lubomir Bulej <pallas at kadan.cz>
+# - various cosmetic fixes
+# v0.6 - Lubomir Bulej <pallas at kadan.cz>
+# - attempt to limit number of spawned processes by utilizing
+# more of sed power (use sed instead of grep+cut)
+# - simplified TIME parser, using bash builtins
+# - added initial support for SFQ as leaf qdisc
+# - reworked the documentation part a little
+# - incorporated pending patches and ideas submitted by
+# following people for versions 0.3 into version 0.6
+# - Miguel Freitas <miguel at cetuc.puc-rio.br>
+# - in case of overlapping TIME parameters, the last match is taken
+# - Juanjo Ciarlante <jjo at mendoza.gov.ar>
+# - chkconfig tags, list + stats startup parameters
+# - optional tc & ip command logging (into /var/run/cbq-*)
+# - Rafal Maszkowski <rzm at icm.edu.pl>
+# - PEAK parameter for setting TBF's burst peak rate
+# - fix for many config files (use find instead of ls)
+# v0.5.1- Lubomir Bulej <pallas at kadan.cz>
+# - fixed little but serious bug in RULE parser
+# v0.5 - Lubomir Bulej <pallas at kadan.cz>
+# - added options PARENT, LEAF, ISOLATED and BOUNDED. This allows
+# (with some attention to config file ordering) for creating
+# hierarchical structures of shapers with classes able (or unable)
+# to borrow bandwidth from their parents.
+# - class ID check allows hexadecimal numbers
+# - rewritten & simplified RULE parser
+# - cosmetic changes to improve readability
+# - reorganization to avoid duplicate code (timecheck etc.)
+# - timecheck doesn't check classes without TIME fields anymore
+# v0.4 - Lubomir Bulej <pallas at kadan.cz>
+# - small bugfix in RULE parsing code
+# - simplified configuration parsing code
+# - several small cosmetic changes
+# - TIME parameter can be now specified more than once allowing you to
+# differentiate RATE throughout the whole day. Time overlapping is
+# not checked, first match is taken. Midnight wrap (eg. 20:00-6:00)
+# is allowed and taken care of.
+# v0.3a4- fixed small bug in IF operator. Thanks to
+# Rafal Maszkowski <rzm at icm.edu.pl>
+# v0.3a3- fixed grep bug when using more than 10 eth devices. Thanks to David
+# Trcka <trcka at poda.cz>.
+# v0.3a2- fixed bug in "if" operator. Thanks kad at dgtu.donetsk.ua.
+# v0.3a - added TIME parameter. Example: TIME=00:00-19:00;64Kbit/6Kbit
+# So, between 00:00 and 19:00 the RATE will be 64Kbit.
+# Just start "cbq.init timecheck" periodically from cron
+# (every 10 minutes for example). DON'T FORGET though, to run
+# "cbq.init start" for CBQ to initialize.
+# v0.2 - Some cosmetic changes. Now it is more compatible with old bash
+# version. Thanks to Stanislav V. Voronyi <stas at cnti.uanet.kharkov.ua>.
+# v0.1 - First public release
+#
+#
+# README
+# ------
+#
+# First of all - this is just a SIMPLE EXAMPLE of CBQ power.
+# Don't ask me "why" and "how" :)
+#
+# This script is meant to simplify setup and management of relatively simple
+# CBQ-based traffic control on Linux. Access to advanced networking features
+# of Linux kernel is provided by "ip" and "tc" utilities from A. Kuznetsov's
+# iproute2 package, available at ftp://ftp.inr.ac.ru/ip-routing. Because the
+# utilities serve primarily to translate user wishes to RTNETLINK commands,
+# their interface is rather spartan, intolerant and requires quite a lot of
+# typing. And typing is what this script attempts to reduce :)
+#
+# The advanced networking stuff in Linux is pretty flexible and this script
+# aims to bring some of its features to the not-so-hard-core Linux users. Of
+# course, there is a tradeoff between simplicity and flexibility and you may
+# realize that the flexibility suffered too much for your needs -- time to
+# face "ip" and "tc" interface.
+#
+# To speed up the "start" command, simple caching was introduced in version
+# 0.6.4. The caching works so that the sequence of "tc" commands for given
+# configuration is stored in a file (/var/cache/cbq.init by default) which
+# is used next time the "start" command is run to avoid repeated parsing of
+# configuration files. This cache is invalidated whenever any of the CBQ
+# configuration files changes. If you want to run "cbq.init start" without
+# caching, run it as "cbq.init start nocache". If you want to force cache
+# invalidation, run it as "cbq.init start invalidate". Caching is disabled
+# if you have logging enabled (ie. CBQ_DEBUG is not empty).
+#
+# If you only want cqb.init to translate your configuration to "tc" commands,
+# use "compile" command which will output "tc" commands required to build
+# your configuration. Bear in mind that "compile" does not check if the "tc"
+# commands were successful - this is done (in certain places) only when the
+# "start nocache" command is used, which is also useful when creating the
+# configuration to check whether it is completely valid.
+#
+# All CBQ parameters are valid for Ethernet interfaces only, The script was
+# tested on various Linux kernel versions from series 2.1 to 2.4 and several
+# distributions with KSI Linux (Nostromo version) as the premier one.
+#
+#
+# HOW DOES IT WORK?
+# -----------------
+#
+# Every traffic class must be described by a file in the $CBQ_PATH directory
+# (/etc/sysconfig/cbq by default) - one file per class.
+#
+# The config file names must obey mandatory format: cbq-<clsid>.<name> where
+# <clsid> is two-byte hexadecimal number in range <0002-FFFF> (which in fact
+# is a CBQ class ID) and <name> is the name of the class -- anything to help
+# you distinguish the configuration files. For small amount of classes it is
+# often possible (and convenient) to let <clsid> resemble bandwidth of the
+# class.
+#
+# Example of valid config name:
+# cbq-1280.My_first_shaper
+#
+#
+# The configuration file may contain the following parameters:
+#
+### Device parameters
+#
+# DEVICE=<ifname>,<bandwidth>[,<weight>] mandatory
+# DEVICE=eth0,10Mbit,1Mbit
+#
+# <ifname> is the name of the interface you want to control
+# traffic on, e.g. eth0
+# <bandwidth> is the physical bandwidth of the device, e.g. for
+# ethernet 10Mbit or 100Mbit, for arcnet 2Mbit
+# <weight> is tuning parameter that should be proportional to
+# <bandwidth>. As a rule of thumb: <weight> = <bandwidth> / 10
+#
+# When you have more classes on one interface, it is enough to specify
+# <bandwidth> [and <weight>] only once, therefore in other files you only
+# need to set DEVICE=<ifname>.
+#
+### Class parameters
+#
+# RATE=<speed> mandatory
+# RATE=5Mbit
+#
+# Bandwidth allocated to the class. Traffic going through the class is
+# shaped to conform to specified rate. You can use Kbit, Mbit or bps,
+# Kbps and Mbps as suffices. If you don't specify any unit, bits/sec
+# are used. Also note that "bps" means "bytes per second", not bits.
+#
+# WEIGHT=<speed> mandatory
+# WEIGHT=500Kbit
+#
+# Tuning parameter that should be proportional to RATE. As a rule
+# of thumb, use WEIGHT ~= RATE / 10.
+#
+# PRIO=<1-8> optional, default 5
+# PRIO=5
+#
+# Priority of class traffic. The higher the number, the lesser
+# the priority. Priority of 5 is just fine.
+#
+# PARENT=<clsid> optional, default not set
+# PARENT=1280
+#
+# Specifies ID of the parent class to which you want this class be
+# attached. You might want to use LEAF=none for the parent class as
+# mentioned below. By using this parameter and carefully ordering the
+# configuration files, it is possible to create simple hierarchical
+# structures of CBQ classes. The ordering is important so that parent
+# classes are constructed prior to their children.
+#
+# LEAF=none|tbf|sfq optional, default "tbf"
+#
+# Tells the script to attach specified leaf queueing discipline to CBQ
+# class. By default, TBF is used. Note that attaching TBF to CBQ class
+# shapes the traffic to conform to TBF parameters and prevents the class
+# from borrowing bandwidth from its parent even if you have BOUNDED set
+# to "no". To allow the class to borrow bandwith (provided it is not
+# bounded), you must set LEAF to "none" or "sfq".
+#
+# If you want to ensure (approximately) fair sharing of bandwidth among
+# several hosts in the same class, you might want to specify LEAF=sfq to
+# attach SFQ as leaf queueing discipline to that class.
+#
+# BOUNDED=yes|no optional, default "yes"
+#
+# If set to "yes", the class is not allowed to borrow bandwidth from
+# its parent class in overlimit situation. If set to "no", the class
+# will be allowed to borrow bandwidth from its parent.
+#
+# Note: Don't forget to set LEAF to "none" or "sfq", otherwise the class will
+# have TBF attached to itself and will not be able to borrow unused
+# bandwith from its parent.
+#
+# ISOLATED=yes|no optional, default "no"
+#
+# If set to "yes", the class will not lend unused bandwidth to
+# its children.
+#
+### TBF qdisc parameters
+#
+# BUFFER=<bytes>[/<bytes>] optional, default "10Kb/8"
+#
+# This parameter controls the depth of the token bucket. In other
+# words it represents the maximal burst size the class can send.
+# The optional part of parameter is used to determine the length
+# of intervals in packet sizes, for which the transmission times
+# are kept.
+#
+# LIMIT=<bytes> optional, default "15Kb"
+#
+# This parameter determines the maximal length of backlog. If
+# the queue contains more data than specified by LIMIT, the
+# newly arriving packets are dropped. The length of backlog
+# determines queue latency in case of congestion.
+#
+# PEAK=<speed> optional, default not set
+#
+# Maximal peak rate for short-term burst traffic. This allows you
+# to control the absolute peak rate the class can send at, because
+# single TBF that allows 256Kbit/s would of course allow rate of
+# 512Kbit for half a second or 1Mbit for a quarter of second.
+#
+# MTU=<bytes> optional, default "1500"
+#
+# Maximum number of bytes that can be sent at once over the
+# physical medium. This parameter is required when you specify
+# PEAK parameter. It defaults to MTU of ethernet - for other
+# media types you might want to change it.
+#
+# Note: Setting TBF as leaf qdisc will effectively prevent the class from
+# borrowing bandwidth from the ancestor class, because even if the
+# class allows more traffic to pass through, it is then shaped to
+# conform to TBF.
+#
+### SFQ qdisc parameters
+#
+# The SFQ queueing discipline is a cheap way for sharing class bandwidth
+# among several hosts. As it is stochastic, the fairness is approximate but
+# it will do the job in most cases. If you want real fairness, you should
+# probably use WRR (weighted round robin) or WFQ queueing disciplines. Note
+# that SFQ does not do any traffic shaping - the shaping is done by the CBQ
+# class the SFQ is attached to.
+#
+# QUANTUM=<bytes> optional, default not set
+#
+# This parameter should not be set lower than link MTU, for ethernet
+# it is 1500b, or (with MAC header) 1514b which is the value used
+# in Alexey Kuznetsov's examples.
+#
+# PERTURB=<seconds> optional, default "10"
+#
+# Period of hash function perturbation. If unset, hash reconfiguration
+# will never take place which is what you probably don't want. The
+# default value of 10 seconds is probably a good one.
+#
+### Filter parameters
+#
+# RULE=[[saddr[/prefix]][:port[/mask]],][daddr[/prefix]][:port[/mask]]
+#
+# These parameters make up "u32" filter rules that select traffic for
+# each of the classes. You can use multiple RULE fields per config.
+#
+# The optional port mask should only be used by advanced users who
+# understand how the u32 filter works.
+#
+# Some examples:
+#
+# RULE=10.1.1.0/24:80
+# selects traffic going to port 80 in network 10.1.1.0
+#
+# RULE=10.2.2.5
+# selects traffic going to any port on single host 10.2.2.5
+#
+# RULE=10.2.2.5:20/0xfffe
+# selects traffic going to ports 20 and 21 on host 10.2.2.5
+#
+# RULE=:25,10.2.2.128/26:5000
+# selects traffic going from anywhere on port 50 to
+# port 5000 in network 10.2.2.128
+#
+# RULE=10.5.5.5:80,
+# selects traffic going from port 80 of single host 10.5.5.5
+#
+#
+#
+# REALM=[srealm,][drealm]
+#
+# These parameters make up "route" filter rules that classify traffic
+# according to packet source/destination realms. For information about
+# realms, see Alexey Kuznetsov's IP Command Reference. This script
+# does not define any realms, it justs builds "tc filter" commands
+# for you if you need to classify traffic this way.
+#
+# Realm is either a decimal number or a string referencing entry in
+# /etc/iproute2/rt_realms (usually).
+#
+# Some examples:
+#
+# REALM=russia,internet
+# selects traffic going from realm "russia" to realm "internet"
+#
+# REALM=freenet,
+# selects traffic going from realm "freenet"
+#
+# REALM=10
+# selects traffic going to realm 10
+#
+#
+#
+# MARK=<mark>
+#
+# These parameters make up "fw" filter rules that select traffic for
+# each of the classes accoring to firewall "mark". Mark is a decimal
+# number packets are tagged with if firewall rules say so. You can
+# use multiple MARK fields per config.
+#
+#
+# Note: Rules for different filter types can be combined. Attention must be
+# paid to the priority of filter rules, which can be set below using
+# PRIO_{RULE,MARK,REALM} variables.
+#
+### Time ranging parameters
+#
+# TIME=[<dow>,<dow>, ...,<dow>/]<from>-<till>;<rate>/<weight>[/<peak>]
+# TIME=0,1,2,5/18:00-06:00;256Kbit/25Kbit
+# TIME=60123/18:00-06:00;256Kbit/25Kbit
+# TIME=18:00-06:00;256Kbit/25Kbit
+#
+# This parameter allows you to differentiate the class bandwidth
+# throughout the day. You can specify multiple TIME parameters, if
+# the times overlap, last match is taken. The fields <rate>, <weight>
+# and <peak> correspond to parameters RATE, WEIGHT and PEAK (which
+# is optional and applies to TBF leaf qdisc only).
+#
+# You can also specify days of week when the TIME rule applies. <dow>
+# is numeric, 0 corresponds to sunday, 1 corresponds to monday, etc.
+#
+###
+#
+# Sample configuration file: cbq-1280.My_first_shaper
+#
+# --------------------------------------------------------------------------
+# DEVICE=eth0,10Mbit,1Mbit
+# RATE=128Kbit
+# WEIGHT=10Kbit
+# PRIO=5
+# RULE=192.128.1.0/24
+# --------------------------------------------------------------------------
+#
+# The configuration says that we will control traffic on 10Mbit ethernet
+# device eth0 and the traffic going to network 192.168.1.0 will be
+# processed with priority 5 and shaped to rate of 128Kbit.
+#
+# Note that you can control outgoing traffic only. If you want to control
+# traffic in both directions, you must set up CBQ for both interfaces.
+#
+# Consider the following example:
+#
+# +---------+ 192.168.1.1
+# BACKBONE -----eth0-| linux |-eth1------*-[client]
+# +---------+
+#
+# Imagine you want to shape traffic from backbone to the client to 28Kbit
+# and traffic in the opposite direction to 128Kbit. You need to setup CBQ
+# on both eth0 and eth1 interfaces, thus you need two config files:
+#
+# cbq-028.backbone-client
+# --------------------------------------------------------------------------
+# DEVICE=eth1,10Mbit,1Mbit
+# RATE=28Kbit
+# WEIGHT=2Kbit
+# PRIO=5
+# RULE=192.168.1.1
+# --------------------------------------------------------------------------
+#
+# cbq-128.client-backbone
+# --------------------------------------------------------------------------
+# DEVICE=eth0,10Mbit,1Mbit
+# RATE=128Kbit
+# WEIGHT=10Kbit
+# PRIO=5
+# RULE=192.168.1.1,
+# --------------------------------------------------------------------------
+#
+# Pay attention to comma "," in the RULE field - it denotes source address!
+#
+# Enjoy.

+AFCBQ
+-----
+AF PHB built using CBQ, DSMARK,GRED (default in GRIO mode) ,RED for BE
+and the tcindex classifier with some algorithmic mapping
+
+EFCBQ

+EF PHB built using CBQ (for rate control and prioritization),
+DSMARK( to remark DSCPs), tcindex classifier and RED for the BE
+traffic.

+CB-3(1|2)-(u32/chains)
+======================
+
+
+The major differences are that the classifier is u32 on -u32 extension
+and IPchains on the chains extension. CB stands for color Blind
+and 31 is for the mode where only a CIR and CBS are defined whereas
+32 stands for a mode where a CIR/CBS + PIR/EBS are defined.
+
+Color Blind (CB)
+==========-----=
+We look at one special subnet that we are interested in for simplicty
+reasons to demonstrate the capability. We send the packets from that
+subnet to AF4*, BE or end up dropping depending on the metering results.
+
+
+The algorithm overview is as follows:
+
+*classify:
+
+**case: subnet X
+----------------
+ if !exceed meter1 tag as AF41
+ else
+ if !exceed meter2 tag as AF42
+ else
+ if !exceed meter 3 tag as AF43
+ else
+ drop
+
+default case: Any other subnet
+-------------------------------
+ if !exceed meter 5 tag as AF43
+ else
+ drop
+
+
+One Egress side change the DSCPs of the packets to reflect AF4* and BE
+based on the tags from the ingress.
+
+-------------------------------------------------------------
+
+Color Aware
+===========
+
+Define some meters with + policing and give them IDs eg
+
+meter1=police index 1 rate $CIR1 burst $CBS1
+meter2=police index 2 rate $CIR2 burst $CBS2 etc
+
+General overview:
+classify based on the DSCPs and use the policer ids to decide tagging
+
+
+*classify on ingress:
+
+switch (dscp) {
+ case AF41: /* tos&0xfc == 0x88 */
+ if (!exceed meter1) break;
+ case AF42: /* tos&0xfc == 0x90 */
+ if (!exceed meter2) {
+ tag as AF42;
+ break;
+ }
+ case AF43: /* tos&0xfc == 0x98 */
+ if (!exceed meter3) {
+ tag as AF43;
+ break;
+ } else
+ drop;
+ default:
+ if (!exceed meter4) tag as BE;
+ else drop;
+}
+
+On the Egress side mark the proper AF tags

+These were the tests done to validate the Diffserv scripts.
+This document will be updated continously. If you do more
+thorough validation testing please post the details to the
+diffserv mailing list.
+Nevertheless, these tests should serve for basic validation.
+
+AFCBQ, EFCBQ, EFPRIO
+----------------------
+
+generate all possible DSCPs and observe that they
+get sent to the proper classes. In the case of AF also
+to the correct Virtual Queues.
+
+Edge1
+-----
+generate TOS values 0x0,0x10,0xbb each with IP addresses
+10.2.0.24 (mark 1), 10.2.0.3 (mark2) and 10.2.0.30 (mark 3)
+and observe that they get marked as expected.
+
+Edge2
+-----
+
+-Repeat the tests in Edge1
+-ftp with data direction from 10.2.0.2
+ *observe that the metering/policing works correctly (and the marking
+ as well). In this case the mark used will be 3
+
+Edge31-cb-chains
+----------------
+
+-ftp with data direction from 10.2.0.2
+
+ *observe that the metering/policing works correctly (and the marking
+ as well). In this case the mark used will be 1.
+
+ Metering: The data throughput should not exceed 2*CIR1 + 2*CIR2
+ which is roughly: 5mbps
+
+ Marking: the should be a variation of marked packets:
+ AF41(TOS=0x88) AF42(0x90) AF43(0x98) and BE (0x0)
+
+More tests required to see the interaction of several sources (other
+than subnet 10.2.0.0/24).
+
+Edge31-ca-u32
+--------------
+
+Generate data using modified tcpblast from 10.2.0.2 (behind eth2) to the
+discard port of 10.1.0.2 (behind eth1)
+
+1) generate with src tos = 0x88
+ Metering: Allocated throughput should not exceed 2*CIR1 + 2*CIR2
+ approximately 5mbps
+ Marking: Should vary between 0x88,0x90,0x98 and 0x0
+
+2) generate with src tos = 0x90
+ Metering: Allocated throughput should not exceed CIR1 + 2*CIR2
+ approximately 3.5mbps
+ Marking: Should vary between 0x90,0x98 and 0x0
+
+3) generate with src tos = 0x98
+ Metering: Allocated throughput should not exceed CIR1 + CIR2
+ approximately 2.5mbps
+ Marking: Should vary between 0x98 and 0x0
+
+4) generate with src tos any other than the above
+ Metering: Allocated throughput should not exceed CIR1
+ approximately 1.5mbps
+ Marking: Should be consistent at 0x0
+
+TODO: Testing on how each color shares when all 4 types of packets
+are going through the edge device

+Generate data using modified tcpblast from 10.2.0.2 (behind eth2) to the
+discard port of 10.1.0.2 (behind eth1)
+
+1) generate with src tos = 0x88
+ Metering: Allocated throughput should not exceed 2*CIR1 + 2*CIR2
+ +PIR1 -- approximately 4mbps
+ Marking: Should vary between 0x88,0x90,0x98 and 0x0
+
+2) generate with src tos = 0x90
+ Metering: Allocated throughput should not exceed CIR1 + 2*CIR2
+ + 2* PIR2 approximately 3mbps
+ Marking: Should vary between 0x90,0x98 and 0x0
+
+3) generate with src tos = 0x98
+ Metering: Allocated throughput should not exceed PIR1+ CIR1 + CIR2
+ approximately 2.5mbps
+ Marking: Should vary between 0x98 and 0x0
+
+4) generate with src tos any other than the above
+ Metering: Allocated throughput should not exceed CIR1
+ approximately 1mbps
+ Marking: Should be consistent at 0x0
+
+TODO: Testing on how each color shares when all 4 types of packets

+/*
+ * Compatibility interface for userspace libc header coordination:
+ *
+ * Define compatibility macros that are used to control the inclusion or
+ * exclusion of UAPI structures and definitions in coordination with another
+ * userspace C library.
+ *
+ * This header is intended to solve the problem of UAPI definitions that
+ * conflict with userspace definitions. If a UAPI header has such conflicting
+ * definitions then the solution is as follows:
+ *
+ * * Synchronize the UAPI header and the libc headers so either one can be
+ * used and such that the ABI is preserved. If this is not possible then
+ * no simple compatibility interface exists (you need to write translating
+ * wrappers and rename things) and you can't use this interface.
+ *
+ * Then follow this process:
+ *
+ * (a) Include libc-compat.h in the UAPI header.
+ * e.g. #include <linux/libc-compat.h>
+ * This include must be as early as possible.
+ *
+ * (b) In libc-compat.h add enough code to detect that the comflicting
+ * userspace libc header has been included first.
+ *
+ * (c) If the userspace libc header has been included first define a set of
+ * guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
+ * set their values to 0.
+ *
+ * (d) Back in the UAPI header with the conflicting definitions, guard the
+ * definitions with:
+ * #if __UAPI_DEF_FOO
+ * ...
+ * #endif
+ *
+ * This fixes the situation where the linux headers are included *after* the
+ * libc headers. To fix the problem with the inclusion in the other order the
+ * userspace libc headers must be fixed like this:
+ *
+ * * For all definitions that conflict with kernel definitions wrap those
+ * defines in the following:
+ * #if !__UAPI_DEF_FOO
+ * ...
+ * #endif
+ *
+ * This prevents the redefinition of a construct already defined by the kernel.

- *
- * Start of BPF helper function descriptions:
- *
- * void *bpf_map_lookup_elem(struct bpf_map *map, const void *key)
- * Description
- * Perform a lookup in *map* for an entry associated to *key*.
- * Return
- * Map value associated to *key*, or **NULL** if no entry was
- * found.
- *
- * int bpf_map_update_elem(struct bpf_map *map, const void *key, const void *value, u64 flags)
- * Description
- * Add or update the value of the entry associated to *key* in
- * *map* with *value*. *flags* is one of:
- *
- * **BPF_NOEXIST**
- * The entry for *key* must not exist in the map.
- * **BPF_EXIST**
- * The entry for *key* must already exist in the map.
- * **BPF_ANY**
- * No condition on the existence of the entry for *key*.
- *
- * Flag value **BPF_NOEXIST** cannot be used for maps of types
- * **BPF_MAP_TYPE_ARRAY** or **BPF_MAP_TYPE_PERCPU_ARRAY** (all
- * elements always exist), the helper would return an error.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_map_delete_elem(struct bpf_map *map, const void *key)
- * Description
- * Delete entry with *key* from *map*.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_probe_read(void *dst, u32 size, const void *src)
- * Description
- * For tracing programs, safely attempt to read *size* bytes from
- * address *src* and store the data in *dst*.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * u64 bpf_ktime_get_ns(void)
- * Description
- * Return the time elapsed since system boot, in nanoseconds.
- * Return
- * Current *ktime*.
- *
- * int bpf_trace_printk(const char *fmt, u32 fmt_size, ...)
- * Description
- * This helper is a "printk()-like" facility for debugging. It
- * prints a message defined by format *fmt* (of size *fmt_size*)
- * to file *\/sys/kernel/debug/tracing/trace* from DebugFS, if
- * available. It can take up to three additional **u64**
- * arguments (as an eBPF helpers, the total number of arguments is
- * limited to five).
- *
- * Each time the helper is called, it appends a line to the trace.
- * Lines are discarded while *\/sys/kernel/debug/tracing/trace* is
- * open, use *\/sys/kernel/debug/tracing/trace_pipe* to avoid this.
- * The format of the trace is customizable, and the exact output
- * one will get depends on the options set in
- * *\/sys/kernel/debug/tracing/trace_options* (see also the
- * *README* file under the same directory). However, it usually
- * defaults to something like:
- *
- * ::
- *
- * telnet-470 [001] .N.. 419421.045894: 0x00000001: <formatted msg>
- *
- * In the above:
- *
- * * ``telnet`` is the name of the current task.
- * * ``470`` is the PID of the current task.
- * * ``001`` is the CPU number on which the task is
- * running.
- * * In ``.N..``, each character refers to a set of
- * options (whether irqs are enabled, scheduling
- * options, whether hard/softirqs are running, level of
- * preempt_disabled respectively). **N** means that
- * **TIF_NEED_RESCHED** and **PREEMPT_NEED_RESCHED**
- * are set.
- * * ``419421.045894`` is a timestamp.
- * * ``0x00000001`` is a fake value used by BPF for the
- * instruction pointer register.
- * * ``<formatted msg>`` is the message formatted with
- * *fmt*.
- *
- * The conversion specifiers supported by *fmt* are similar, but
- * more limited than for printk(). They are **%d**, **%i**,
- * **%u**, **%x**, **%ld**, **%li**, **%lu**, **%lx**, **%lld**,
- * **%lli**, **%llu**, **%llx**, **%p**, **%s**. No modifier (size
- * of field, padding with zeroes, etc.) is available, and the
- * helper will return **-EINVAL** (but print nothing) if it
- * encounters an unknown specifier.
- *
- * Also, note that **bpf_trace_printk**\ () is slow, and should
- * only be used for debugging purposes. For this reason, a notice
- * bloc (spanning several lines) is printed to kernel logs and
- * states that the helper should not be used "for production use"
- * the first time this helper is used (or more precisely, when
- * **trace_printk**\ () buffers are allocated). For passing values
- * to user space, perf events should be preferred.
- * Return
- * The number of bytes written to the buffer, or a negative error
- * in case of failure.
- *
- * u32 bpf_get_prandom_u32(void)
- * Description
- * Get a pseudo-random number.
- *
- * From a security point of view, this helper uses its own
- * pseudo-random internal state, and cannot be used to infer the
- * seed of other random functions in the kernel. However, it is
- * essential to note that the generator used by the helper is not
- * cryptographically secure.
- * Return
- * A random 32-bit unsigned value.
- *
- * u32 bpf_get_smp_processor_id(void)
- * Description
- * Get the SMP (symmetric multiprocessing) processor id. Note that
- * all programs run with preemption disabled, which means that the
- * SMP processor id is stable during all the execution of the
- * program.
- * Return
- * The SMP id of the processor running the program.
- *
- * int bpf_skb_store_bytes(struct sk_buff *skb, u32 offset, const void *from, u32 len, u64 flags)
- * Description
- * Store *len* bytes from address *from* into the packet
- * associated to *skb*, at *offset*. *flags* are a combination of
- * **BPF_F_RECOMPUTE_CSUM** (automatically recompute the
- * checksum for the packet after storing the bytes) and
- * **BPF_F_INVALIDATE_HASH** (set *skb*\ **->hash**, *skb*\
- * **->swhash** and *skb*\ **->l4hash** to 0).
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_l3_csum_replace(struct sk_buff *skb, u32 offset, u64 from, u64 to, u64 size)
- * Description
- * Recompute the layer 3 (e.g. IP) checksum for the packet
- * associated to *skb*. Computation is incremental, so the helper
- * must know the former value of the header field that was
- * modified (*from*), the new value of this field (*to*), and the
- * number of bytes (2 or 4) for this field, stored in *size*.
- * Alternatively, it is possible to store the difference between
- * the previous and the new values of the header field in *to*, by
- * setting *from* and *size* to 0. For both methods, *offset*
- * indicates the location of the IP checksum within the packet.
- *
- * This helper works in combination with **bpf_csum_diff**\ (),
- * which does not update the checksum in-place, but offers more
- * flexibility and can handle sizes larger than 2 or 4 for the
- * checksum to update.

- *
- * int bpf_l4_csum_replace(struct sk_buff *skb, u32 offset, u64 from, u64 to, u64 flags)
- * Description
- * Recompute the layer 4 (e.g. TCP, UDP or ICMP) checksum for the
- * packet associated to *skb*. Computation is incremental, so the
- * helper must know the former value of the header field that was
- * modified (*from*), the new value of this field (*to*), and the
- * number of bytes (2 or 4) for this field, stored on the lowest
- * four bits of *flags*. Alternatively, it is possible to store
- * the difference between the previous and the new values of the
- * header field in *to*, by setting *from* and the four lowest
- * bits of *flags* to 0. For both methods, *offset* indicates the
- * location of the IP checksum within the packet. In addition to
- * the size of the field, *flags* can be added (bitwise OR) actual
- * flags. With **BPF_F_MARK_MANGLED_0**, a null checksum is left
- * untouched (unless **BPF_F_MARK_ENFORCE** is added as well), and
- * for updates resulting in a null checksum the value is set to
- * **CSUM_MANGLED_0** instead. Flag **BPF_F_PSEUDO_HDR** indicates
- * the checksum is to be computed against a pseudo-header.
- *
- * This helper works in combination with **bpf_csum_diff**\ (),
- * which does not update the checksum in-place, but offers more
- * flexibility and can handle sizes larger than 2 or 4 for the
- * checksum to update.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with

- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_tail_call(void *ctx, struct bpf_map *prog_array_map, u32 index)
- * Description
- * This special helper is used to trigger a "tail call", or in
- * other words, to jump into another eBPF program. The same stack
- * frame is used (but values on stack and in registers for the
- * caller are not accessible to the callee). This mechanism allows
- * for program chaining, either for raising the maximum number of
- * available eBPF instructions, or to execute given programs in
- * conditional blocks. For security reasons, there is an upper
- * limit to the number of successive tail calls that can be
- * performed.
- *
- * Upon call of this helper, the program attempts to jump into a
- * program referenced at index *index* in *prog_array_map*, a
- * special map of type **BPF_MAP_TYPE_PROG_ARRAY**, and passes
- * *ctx*, a pointer to the context.
- *
- * If the call succeeds, the kernel immediately runs the first
- * instruction of the new program. This is not a function call,
- * and it never returns to the previous program. If the call
- * fails, then the helper has no effect, and the caller continues
- * to run its subsequent instructions. A call can fail if the
- * destination program for the jump does not exist (i.e. *index*
- * is superior to the number of entries in *prog_array_map*), or
- * if the maximum number of tail calls has been reached for this
- * chain of programs. This limit is defined in the kernel by the
- * macro **MAX_TAIL_CALL_CNT** (not accessible to user space),
- * which is currently set to 32.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_clone_redirect(struct sk_buff *skb, u32 ifindex, u64 flags)
- * Description
- * Clone and redirect the packet associated to *skb* to another
- * net device of index *ifindex*. Both ingress and egress
- * interfaces can be used for redirection. The **BPF_F_INGRESS**
- * value in *flags* is used to make the distinction (ingress path
- * is selected if the flag is present, egress path otherwise).
- * This is the only flag supported for now.
- *
- * In comparison with **bpf_redirect**\ () helper,
- * **bpf_clone_redirect**\ () has the associated cost of
- * duplicating the packet buffer, but this can be executed out of
- * the eBPF program. Conversely, **bpf_redirect**\ () is more
- * efficient, but it is handled through an action code where the
- * redirection happens only after the eBPF program has returned.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * u64 bpf_get_current_pid_tgid(void)
- * Return
- * A 64-bit integer containing the current tgid and pid, and
- * created as such:
- * *current_task*\ **->tgid << 32 \|**
- * *current_task*\ **->pid**.
- *
- * u64 bpf_get_current_uid_gid(void)
- * Return
- * A 64-bit integer containing the current GID and UID, and
- * created as such: *current_gid* **<< 32 \|** *current_uid*.
- *
- * int bpf_get_current_comm(char *buf, u32 size_of_buf)
- * Description
- * Copy the **comm** attribute of the current task into *buf* of
- * *size_of_buf*. The **comm** attribute contains the name of
- * the executable (excluding the path) for the current task. The
- * *size_of_buf* must be strictly positive. On success, the
- * helper makes sure that the *buf* is NUL-terminated. On failure,
- * it is filled with zeroes.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * u32 bpf_get_cgroup_classid(struct sk_buff *skb)
- * Description
- * Retrieve the classid for the current task, i.e. for the net_cls
- * cgroup to which *skb* belongs.
- *
- * This helper can be used on TC egress path, but not on ingress.
- *
- * The net_cls cgroup provides an interface to tag network packets
- * based on a user-provided identifier for all traffic coming from
- * the tasks belonging to the related cgroup. See also the related
- * kernel documentation, available from the Linux sources in file
- * *Documentation/admin-guide/cgroup-v1/net_cls.rst*.
- *
- * The Linux kernel has two versions for cgroups: there are
- * cgroups v1 and cgroups v2. Both are available to users, who can
- * use a mixture of them, but note that the net_cls cgroup is for
- * cgroup v1 only. This makes it incompatible with BPF programs
- * run on cgroups, which is a cgroup-v2-only feature (a socket can
- * only hold data for one version of cgroups at a time).
- *
- * This helper is only available is the kernel was compiled with
- * the **CONFIG_CGROUP_NET_CLASSID** configuration option set to
- * "**y**" or to "**m**".
- * Return
- * The classid, or 0 for the default unconfigured classid.
- *
- * int bpf_skb_vlan_push(struct sk_buff *skb, __be16 vlan_proto, u16 vlan_tci)
- * Description
- * Push a *vlan_tci* (VLAN tag control information) of protocol
- * *vlan_proto* to the packet associated to *skb*, then update
- * the checksum. Note that if *vlan_proto* is different from
- * **ETH_P_8021Q** and **ETH_P_8021AD**, it is considered to
- * be **ETH_P_8021Q**.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_vlan_pop(struct sk_buff *skb)
- * Description
- * Pop a VLAN header from the packet associated to *skb*.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_get_tunnel_key(struct sk_buff *skb, struct bpf_tunnel_key *key, u32 size, u64 flags)
- * Description
- * Get tunnel metadata. This helper takes a pointer *key* to an
- * empty **struct bpf_tunnel_key** of **size**, that will be
- * filled with tunnel metadata for the packet associated to *skb*.
- * The *flags* can be set to **BPF_F_TUNINFO_IPV6**, which
- * indicates that the tunnel is based on IPv6 protocol instead of
- * IPv4.
- *
- * The **struct bpf_tunnel_key** is an object that generalizes the
- * principal parameters used by various tunneling protocols into a
- * single struct. This way, it can be used to easily make a
- * decision based on the contents of the encapsulation header,
- * "summarized" in this struct. In particular, it holds the IP
- * address of the remote end (IPv4 or IPv6, depending on the case)
- * in *key*\ **->remote_ipv4** or *key*\ **->remote_ipv6**. Also,
- * this struct exposes the *key*\ **->tunnel_id**, which is
- * generally mapped to a VNI (Virtual Network Identifier), making
- * it programmable together with the **bpf_skb_set_tunnel_key**\
- * () helper.
- *
- * Let's imagine that the following code is part of a program
- * attached to the TC ingress interface, on one end of a GRE
- * tunnel, and is supposed to filter out all messages coming from
- * remote ends with IPv4 address other than 10.0.0.1:
- *
- * ::
- *
- * int ret;
- * struct bpf_tunnel_key key = {};
- *
- * ret = bpf_skb_get_tunnel_key(skb, &key, sizeof(key), 0);
- * if (ret < 0)
- * return TC_ACT_SHOT; // drop packet
- *
- * if (key.remote_ipv4 != 0x0a000001)
- * return TC_ACT_SHOT; // drop packet
- *
- * return TC_ACT_OK; // accept packet
- *
- * This interface can also be used with all encapsulation devices
- * that can operate in "collect metadata" mode: instead of having
- * one network device per specific configuration, the "collect
- * metadata" mode only requires a single device where the
- * configuration can be extracted from this helper.
- *
- * This can be used together with various tunnels such as VXLan,
- * Geneve, GRE or IP in IP (IPIP).
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_set_tunnel_key(struct sk_buff *skb, struct bpf_tunnel_key *key, u32 size, u64 flags)
- * Description
- * Populate tunnel metadata for packet associated to *skb.* The
- * tunnel metadata is set to the contents of *key*, of *size*. The
- * *flags* can be set to a combination of the following values:
- *
- * **BPF_F_TUNINFO_IPV6**
- * Indicate that the tunnel is based on IPv6 protocol
- * instead of IPv4.
- * **BPF_F_ZERO_CSUM_TX**
- * For IPv4 packets, add a flag to tunnel metadata
- * indicating that checksum computation should be skipped
- * and checksum set to zeroes.
- * **BPF_F_DONT_FRAGMENT**
- * Add a flag to tunnel metadata indicating that the
- * packet should not be fragmented.
- * **BPF_F_SEQ_NUMBER**
- * Add a flag to tunnel metadata indicating that a
- * sequence number should be added to tunnel header before
- * sending the packet. This flag was added for GRE
- * encapsulation, but might be used with other protocols
- * as well in the future.
- *
- * Here is a typical usage on the transmit path:
- *
- * ::
- *
- * struct bpf_tunnel_key key;
- * populate key ...
- * bpf_skb_set_tunnel_key(skb, &key, sizeof(key), 0);
- * bpf_clone_redirect(skb, vxlan_dev_ifindex, 0);
- *
- * See also the description of the **bpf_skb_get_tunnel_key**\ ()
- * helper for additional information.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * u64 bpf_perf_event_read(struct bpf_map *map, u64 flags)
- * Description
- * Read the value of a perf event counter. This helper relies on a
- * *map* of type **BPF_MAP_TYPE_PERF_EVENT_ARRAY**. The nature of
- * the perf event counter is selected when *map* is updated with
- * perf event file descriptors. The *map* is an array whose size
- * is the number of available CPUs, and each cell contains a value
- * relative to one CPU. The value to retrieve is indicated by
- * *flags*, that contains the index of the CPU to look up, masked
- * with **BPF_F_INDEX_MASK**. Alternatively, *flags* can be set to
- * **BPF_F_CURRENT_CPU** to indicate that the value for the
- * current CPU should be retrieved.
- *
- * Note that before Linux 4.13, only hardware perf event can be
- * retrieved.
- *
- * Also, be aware that the newer helper
- * **bpf_perf_event_read_value**\ () is recommended over
- * **bpf_perf_event_read**\ () in general. The latter has some ABI
- * quirks where error and counter value are used as a return code
- * (which is wrong to do since ranges may overlap). This issue is
- * fixed with **bpf_perf_event_read_value**\ (), which at the same
- * time provides more features over the **bpf_perf_event_read**\
- * () interface. Please refer to the description of
- * **bpf_perf_event_read_value**\ () for details.
- * Return
- * The value of the perf event counter read from the map, or a
- * negative error code in case of failure.
- *
- * int bpf_redirect(u32 ifindex, u64 flags)
- * Description
- * Redirect the packet to another net device of index *ifindex*.
- * This helper is somewhat similar to **bpf_clone_redirect**\
- * (), except that the packet is not cloned, which provides
- * increased performance.
- *
- * Except for XDP, both ingress and egress interfaces can be used
- * for redirection. The **BPF_F_INGRESS** value in *flags* is used
- * to make the distinction (ingress path is selected if the flag
- * is present, egress path otherwise). Currently, XDP only
- * supports redirection to the egress interface, and accepts no
- * flag at all.
- *
- * The same effect can be attained with the more generic
- * **bpf_redirect_map**\ (), which requires specific maps to be
- * used but offers better performance.
- * Return
- * For XDP, the helper returns **XDP_REDIRECT** on success or
- * **XDP_ABORTED** on error. For other program types, the values
- * are **TC_ACT_REDIRECT** on success or **TC_ACT_SHOT** on
- * error.
- *
- * u32 bpf_get_route_realm(struct sk_buff *skb)
- * Description
- * Retrieve the realm or the route, that is to say the
- * **tclassid** field of the destination for the *skb*. The
- * indentifier retrieved is a user-provided tag, similar to the
- * one used with the net_cls cgroup (see description for
- * **bpf_get_cgroup_classid**\ () helper), but here this tag is
- * held by a route (a destination entry), not by a task.
- *
- * Retrieving this identifier works with the clsact TC egress hook
- * (see also **tc-bpf(8)**), or alternatively on conventional
- * classful egress qdiscs, but not on TC ingress path. In case of
- * clsact TC egress hook, this has the advantage that, internally,
- * the destination entry has not been dropped yet in the transmit
- * path. Therefore, the destination entry does not need to be
- * artificially held via **netif_keep_dst**\ () for a classful
- * qdisc until the *skb* is freed.
- *
- * This helper is available only if the kernel was compiled with
- * **CONFIG_IP_ROUTE_CLASSID** configuration option.
- * Return
- * The realm of the route for the packet associated to *skb*, or 0
- * if none was found.
- *
- * int bpf_perf_event_output(struct pt_regs *ctx, struct bpf_map *map, u64 flags, void *data, u64 size)
- * Description
- * Write raw *data* blob into a special BPF perf event held by
- * *map* of type **BPF_MAP_TYPE_PERF_EVENT_ARRAY**. This perf
- * event must have the following attributes: **PERF_SAMPLE_RAW**
- * as **sample_type**, **PERF_TYPE_SOFTWARE** as **type**, and
- * **PERF_COUNT_SW_BPF_OUTPUT** as **config**.
- *
- * The *flags* are used to indicate the index in *map* for which
- * the value must be put, masked with **BPF_F_INDEX_MASK**.
- * Alternatively, *flags* can be set to **BPF_F_CURRENT_CPU**
- * to indicate that the index of the current CPU core should be
- * used.
- *
- * The value to write, of *size*, is passed through eBPF stack and
- * pointed by *data*.
- *
- * The context of the program *ctx* needs also be passed to the
- * helper.
- *
- * On user space, a program willing to read the values needs to
- * call **perf_event_open**\ () on the perf event (either for
- * one or for all CPUs) and to store the file descriptor into the
- * *map*. This must be done before the eBPF program can send data
- * into it. An example is available in file
- * *samples/bpf/trace_output_user.c* in the Linux kernel source
- * tree (the eBPF program counterpart is in
- * *samples/bpf/trace_output_kern.c*).
- *
- * **bpf_perf_event_output**\ () achieves better performance
- * than **bpf_trace_printk**\ () for sharing data with user
- * space, and is much better suitable for streaming data from eBPF
- * programs.
- *
- * Note that this helper is not restricted to tracing use cases
- * and can be used with programs attached to TC or XDP as well,
- * where it allows for passing data to user space listeners. Data
- * can be:
- *
- * * Only custom structs,
- * * Only the packet payload, or
- * * A combination of both.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_load_bytes(const struct sk_buff *skb, u32 offset, void *to, u32 len)
- * Description
- * This helper was provided as an easy way to load data from a
- * packet. It can be used to load *len* bytes from *offset* from
- * the packet associated to *skb*, into the buffer pointed by
- * *to*.
- *
- * Since Linux 4.7, usage of this helper has mostly been replaced
- * by "direct packet access", enabling packet data to be
- * manipulated with *skb*\ **->data** and *skb*\ **->data_end**
- * pointing respectively to the first byte of packet data and to
- * the byte after the last byte of packet data. However, it
- * remains useful if one wishes to read large quantities of data
- * at once from a packet into the eBPF stack.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_get_stackid(struct pt_regs *ctx, struct bpf_map *map, u64 flags)
- * Description
- * Walk a user or a kernel stack and return its id. To achieve
- * this, the helper needs *ctx*, which is a pointer to the context
- * on which the tracing program is executed, and a pointer to a
- * *map* of type **BPF_MAP_TYPE_STACK_TRACE**.
- *
- * The last argument, *flags*, holds the number of stack frames to
- * skip (from 0 to 255), masked with
- * **BPF_F_SKIP_FIELD_MASK**. The next bits can be used to set
- * a combination of the following flags:
- *
- * **BPF_F_USER_STACK**
- * Collect a user space stack instead of a kernel stack.
- * **BPF_F_FAST_STACK_CMP**
- * Compare stacks by hash only.
- * **BPF_F_REUSE_STACKID**
- * If two different stacks hash into the same *stackid*,
- * discard the old one.
- *
- * The stack id retrieved is a 32 bit long integer handle which
- * can be further combined with other data (including other stack
- * ids) and used as a key into maps. This can be useful for
- * generating a variety of graphs (such as flame graphs or off-cpu
- * graphs).
- *
- * For walking a stack, this helper is an improvement over
- * **bpf_probe_read**\ (), which can be used with unrolled loops
- * but is not efficient and consumes a lot of eBPF instructions.
- * Instead, **bpf_get_stackid**\ () can collect up to
- * **PERF_MAX_STACK_DEPTH** both kernel and user frames. Note that
- * this limit can be controlled with the **sysctl** program, and
- * that it should be manually increased in order to profile long
- * user stacks (such as stacks for Java programs). To do so, use:
- *
- * ::
- *
- * # sysctl kernel.perf_event_max_stack=<new value>
- * Return
- * The positive or null stack id on success, or a negative error
- * in case of failure.
- *
- * s64 bpf_csum_diff(__be32 *from, u32 from_size, __be32 *to, u32 to_size, __wsum seed)
- * Description
- * Compute a checksum difference, from the raw buffer pointed by
- * *from*, of length *from_size* (that must be a multiple of 4),
- * towards the raw buffer pointed by *to*, of size *to_size*
- * (same remark). An optional *seed* can be added to the value
- * (this can be cascaded, the seed may come from a previous call
- * to the helper).
- *
- * This is flexible enough to be used in several ways:
- *
- * * With *from_size* == 0, *to_size* > 0 and *seed* set to
- * checksum, it can be used when pushing new data.
- * * With *from_size* > 0, *to_size* == 0 and *seed* set to
- * checksum, it can be used when removing data from a packet.
- * * With *from_size* > 0, *to_size* > 0 and *seed* set to 0, it
- * can be used to compute a diff. Note that *from_size* and
- * *to_size* do not need to be equal.
- *
- * This helper can be used in combination with
- * **bpf_l3_csum_replace**\ () and **bpf_l4_csum_replace**\ (), to
- * which one can feed in the difference computed with
- * **bpf_csum_diff**\ ().
- * Return
- * The checksum result, or a negative error code in case of
- * failure.
- *
- * int bpf_skb_get_tunnel_opt(struct sk_buff *skb, u8 *opt, u32 size)
- * Description
- * Retrieve tunnel options metadata for the packet associated to
- * *skb*, and store the raw tunnel option data to the buffer *opt*
- * of *size*.
- *
- * This helper can be used with encapsulation devices that can
- * operate in "collect metadata" mode (please refer to the related
- * note in the description of **bpf_skb_get_tunnel_key**\ () for
- * more details). A particular example where this can be used is
- * in combination with the Geneve encapsulation protocol, where it
- * allows for pushing (with **bpf_skb_get_tunnel_opt**\ () helper)
- * and retrieving arbitrary TLVs (Type-Length-Value headers) from
- * the eBPF program. This allows for full customization of these
- * headers.
- * Return
- * The size of the option data retrieved.
- *
- * int bpf_skb_set_tunnel_opt(struct sk_buff *skb, u8 *opt, u32 size)
- * Description
- * Set tunnel options metadata for the packet associated to *skb*
- * to the option data contained in the raw buffer *opt* of *size*.
- *
- * See also the description of the **bpf_skb_get_tunnel_opt**\ ()
- * helper for additional information.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_change_proto(struct sk_buff *skb, __be16 proto, u64 flags)
- * Description
- * Change the protocol of the *skb* to *proto*. Currently
- * supported are transition from IPv4 to IPv6, and from IPv6 to
- * IPv4. The helper takes care of the groundwork for the
- * transition, including resizing the socket buffer. The eBPF
- * program is expected to fill the new headers, if any, via
- * **skb_store_bytes**\ () and to recompute the checksums with
- * **bpf_l3_csum_replace**\ () and **bpf_l4_csum_replace**\
- * (). The main case for this helper is to perform NAT64
- * operations out of an eBPF program.
- *
- * Internally, the GSO type is marked as dodgy so that headers are
- * checked and segments are recalculated by the GSO/GRO engine.
- * The size for GSO target is adapted as well.
- *
- * All values for *flags* are reserved for future usage, and must
- * be left at zero.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_change_type(struct sk_buff *skb, u32 type)
- * Description
- * Change the packet type for the packet associated to *skb*. This
- * comes down to setting *skb*\ **->pkt_type** to *type*, except
- * the eBPF program does not have a write access to *skb*\
- * **->pkt_type** beside this helper. Using a helper here allows
- * for graceful handling of errors.
- *
- * The major use case is to change incoming *skb*s to
- * **PACKET_HOST** in a programmatic way instead of having to
- * recirculate via **redirect**\ (..., **BPF_F_INGRESS**), for
- * example.
- *
- * Note that *type* only allows certain values. At this time, they
- * are:
- *
- * **PACKET_HOST**
- * Packet is for us.
- * **PACKET_BROADCAST**
- * Send packet to all.
- * **PACKET_MULTICAST**
- * Send packet to group.
- * **PACKET_OTHERHOST**
- * Send packet to someone else.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_under_cgroup(struct sk_buff *skb, struct bpf_map *map, u32 index)
- * Description
- * Check whether *skb* is a descendant of the cgroup2 held by
- * *map* of type **BPF_MAP_TYPE_CGROUP_ARRAY**, at *index*.
- * Return
- * The return value depends on the result of the test, and can be:
- *
- * * 0, if the *skb* failed the cgroup2 descendant test.
- * * 1, if the *skb* succeeded the cgroup2 descendant test.
- * * A negative error code, if an error occurred.
- *
- * u32 bpf_get_hash_recalc(struct sk_buff *skb)
- * Description
- * Retrieve the hash of the packet, *skb*\ **->hash**. If it is
- * not set, in particular if the hash was cleared due to mangling,
- * recompute this hash. Later accesses to the hash can be done
- * directly with *skb*\ **->hash**.
- *
- * Calling **bpf_set_hash_invalid**\ (), changing a packet
- * prototype with **bpf_skb_change_proto**\ (), or calling
- * **bpf_skb_store_bytes**\ () with the
- * **BPF_F_INVALIDATE_HASH** are actions susceptible to clear
- * the hash and to trigger a new computation for the next call to
- * **bpf_get_hash_recalc**\ ().
- * Return
- * The 32-bit hash.
- *
- * u64 bpf_get_current_task(void)
- * Return
- * A pointer to the current task struct.
- *
- * int bpf_probe_write_user(void *dst, const void *src, u32 len)
- * Description
- * Attempt in a safe way to write *len* bytes from the buffer
- * *src* to *dst* in memory. It only works for threads that are in
- * user context, and *dst* must be a valid user space address.
- *
- * This helper should not be used to implement any kind of
- * security mechanism because of TOC-TOU attacks, but rather to
- * debug, divert, and manipulate execution of semi-cooperative
- * processes.
- *
- * Keep in mind that this feature is meant for experiments, and it
- * has a risk of crashing the system and running programs.
- * Therefore, when an eBPF program using this helper is attached,
- * a warning including PID and process name is printed to kernel
- * logs.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_current_task_under_cgroup(struct bpf_map *map, u32 index)
- * Description
- * Check whether the probe is being run is the context of a given
- * subset of the cgroup2 hierarchy. The cgroup2 to test is held by
- * *map* of type **BPF_MAP_TYPE_CGROUP_ARRAY**, at *index*.
- * Return
- * The return value depends on the result of the test, and can be:
- *
- * * 0, if the *skb* task belongs to the cgroup2.
- * * 1, if the *skb* task does not belong to the cgroup2.
- * * A negative error code, if an error occurred.
- *
- * int bpf_skb_change_tail(struct sk_buff *skb, u32 len, u64 flags)
- * Description
- * Resize (trim or grow) the packet associated to *skb* to the
- * new *len*. The *flags* are reserved for future usage, and must
- * be left at zero.
- *
- * The basic idea is that the helper performs the needed work to
- * change the size of the packet, then the eBPF program rewrites
- * the rest via helpers like **bpf_skb_store_bytes**\ (),
- * **bpf_l3_csum_replace**\ (), **bpf_l3_csum_replace**\ ()
- * and others. This helper is a slow path utility intended for
- * replies with control messages. And because it is targeted for
- * slow path, the helper itself can afford to be slow: it
- * implicitly linearizes, unclones and drops offloads from the
- * *skb*.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_pull_data(struct sk_buff *skb, u32 len)
- * Description
- * Pull in non-linear data in case the *skb* is non-linear and not
- * all of *len* are part of the linear section. Make *len* bytes
- * from *skb* readable and writable. If a zero value is passed for
- * *len*, then the whole length of the *skb* is pulled.
- *
- * This helper is only needed for reading and writing with direct
- * packet access.
- *
- * For direct packet access, testing that offsets to access
- * are within packet boundaries (test on *skb*\ **->data_end**) is
- * susceptible to fail if offsets are invalid, or if the requested
- * data is in non-linear parts of the *skb*. On failure the
- * program can just bail out, or in the case of a non-linear
- * buffer, use a helper to make the data available. The
- * **bpf_skb_load_bytes**\ () helper is a first solution to access
- * the data. Another one consists in using **bpf_skb_pull_data**
- * to pull in once the non-linear parts, then retesting and
- * eventually access the data.
- *
- * At the same time, this also makes sure the *skb* is uncloned,
- * which is a necessary condition for direct write. As this needs
- * to be an invariant for the write part only, the verifier
- * detects writes and adds a prologue that is calling
- * **bpf_skb_pull_data()** to effectively unclone the *skb* from
- * the very beginning in case it is indeed cloned.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * s64 bpf_csum_update(struct sk_buff *skb, __wsum csum)
- * Description
- * Add the checksum *csum* into *skb*\ **->csum** in case the
- * driver has supplied a checksum for the entire packet into that
- * field. Return an error otherwise. This helper is intended to be
- * used in combination with **bpf_csum_diff**\ (), in particular
- * when the checksum needs to be updated after data has been
- * written into the packet through direct packet access.
- * Return
- * The checksum on success, or a negative error code in case of
- * failure.
- *
- * void bpf_set_hash_invalid(struct sk_buff *skb)
- * Description
- * Invalidate the current *skb*\ **->hash**. It can be used after
- * mangling on headers through direct packet access, in order to
- * indicate that the hash is outdated and to trigger a
- * recalculation the next time the kernel tries to access this
- * hash or when the **bpf_get_hash_recalc**\ () helper is called.
- *
- * int bpf_get_numa_node_id(void)
- * Description
- * Return the id of the current NUMA node. The primary use case
- * for this helper is the selection of sockets for the local NUMA
- * node, when the program is attached to sockets using the
- * **SO_ATTACH_REUSEPORT_EBPF** option (see also **socket(7)**),
- * but the helper is also available to other eBPF program types,
- * similarly to **bpf_get_smp_processor_id**\ ().
- * Return
- * The id of current NUMA node.
- *
- * int bpf_skb_change_head(struct sk_buff *skb, u32 len, u64 flags)
- * Description
- * Grows headroom of packet associated to *skb* and adjusts the
- * offset of the MAC header accordingly, adding *len* bytes of
- * space. It automatically extends and reallocates memory as
- * required.
- *
- * This helper can be used on a layer 3 *skb* to push a MAC header
- * for redirection into a layer 2 device.
- *
- * All values for *flags* are reserved for future usage, and must
- * be left at zero.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_xdp_adjust_head(struct xdp_buff *xdp_md, int delta)
- * Description
- * Adjust (move) *xdp_md*\ **->data** by *delta* bytes. Note that
- * it is possible to use a negative value for *delta*. This helper
- * can be used to prepare the packet for pushing or popping
- * headers.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_probe_read_str(void *dst, int size, const void *unsafe_ptr)
- * Description
- * Copy a NUL terminated string from an unsafe address
- * *unsafe_ptr* to *dst*. The *size* should include the
- * terminating NUL byte. In case the string length is smaller than
- * *size*, the target is not padded with further NUL bytes. If the
- * string length is larger than *size*, just *size*-1 bytes are
- * copied and the last byte is set to NUL.
- *
- * On success, the length of the copied string is returned. This
- * makes this helper useful in tracing programs for reading
- * strings, and more importantly to get its length at runtime. See
- * the following snippet:
- *
- * ::
- *
- * SEC("kprobe/sys_open")
- * void bpf_sys_open(struct pt_regs *ctx)
- * {
- * char buf[PATHLEN]; // PATHLEN is defined to 256
- * int res = bpf_probe_read_str(buf, sizeof(buf),
- * ctx->di);
- *
- * // Consume buf, for example push it to
- * // userspace via bpf_perf_event_output(); we
- * // can use res (the string length) as event
- * // size, after checking its boundaries.
- * }
- *
- * In comparison, using **bpf_probe_read()** helper here instead
- * to read the string would require to estimate the length at
- * compile time, and would often result in copying more memory
- * than necessary.
- *
- * Another useful use case is when parsing individual process
- * arguments or individual environment variables navigating
- * *current*\ **->mm->arg_start** and *current*\
- * **->mm->env_start**: using this helper and the return value,
- * one can quickly iterate at the right offset of the memory area.
- * Return
- * On success, the strictly positive length of the string,
- * including the trailing NUL character. On error, a negative
- * value.
- *
- * u64 bpf_get_socket_cookie(struct sk_buff *skb)
- * Description
- * If the **struct sk_buff** pointed by *skb* has a known socket,
- * retrieve the cookie (generated by the kernel) of this socket.
- * If no cookie has been set yet, generate a new cookie. Once
- * generated, the socket cookie remains stable for the life of the
- * socket. This helper can be useful for monitoring per socket
- * networking traffic statistics as it provides a global socket
- * identifier that can be assumed unique.
- * Return
- * A 8-byte long non-decreasing number on success, or 0 if the
- * socket field is missing inside *skb*.
- *
- * u64 bpf_get_socket_cookie(struct bpf_sock_addr *ctx)
- * Description
- * Equivalent to bpf_get_socket_cookie() helper that accepts
- * *skb*, but gets socket from **struct bpf_sock_addr** context.
- * Return
- * A 8-byte long non-decreasing number.
- *
- * u64 bpf_get_socket_cookie(struct bpf_sock_ops *ctx)
- * Description
- * Equivalent to bpf_get_socket_cookie() helper that accepts
- * *skb*, but gets socket from **struct bpf_sock_ops** context.
- * Return
- * A 8-byte long non-decreasing number.
- *
- * u32 bpf_get_socket_uid(struct sk_buff *skb)
- * Return
- * The owner UID of the socket associated to *skb*. If the socket
- * is **NULL**, or if it is not a full socket (i.e. if it is a
- * time-wait or a request socket instead), **overflowuid** value
- * is returned (note that **overflowuid** might also be the actual
- * UID value for the socket).
- *
- * u32 bpf_set_hash(struct sk_buff *skb, u32 hash)
- * Description
- * Set the full hash for *skb* (set the field *skb*\ **->hash**)
- * to value *hash*.
- * Return
- * 0
- *
- * int bpf_setsockopt(struct bpf_sock_ops *bpf_socket, int level, int optname, char *optval, int optlen)
- * Description
- * Emulate a call to **setsockopt()** on the socket associated to
- * *bpf_socket*, which must be a full socket. The *level* at
- * which the option resides and the name *optname* of the option
- * must be specified, see **setsockopt(2)** for more information.
- * The option value of length *optlen* is pointed by *optval*.
- *
- * This helper actually implements a subset of **setsockopt()**.
- * It supports the following *level*\ s:
- *
- * * **SOL_SOCKET**, which supports the following *optname*\ s:
- * **SO_RCVBUF**, **SO_SNDBUF**, **SO_MAX_PACING_RATE**,
- * **SO_PRIORITY**, **SO_RCVLOWAT**, **SO_MARK**.
- * * **IPPROTO_TCP**, which supports the following *optname*\ s:
- * **TCP_CONGESTION**, **TCP_BPF_IW**,
- * **TCP_BPF_SNDCWND_CLAMP**.
- * * **IPPROTO_IP**, which supports *optname* **IP_TOS**.
- * * **IPPROTO_IPV6**, which supports *optname* **IPV6_TCLASS**.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_adjust_room(struct sk_buff *skb, s32 len_diff, u32 mode, u64 flags)
- * Description
- * Grow or shrink the room for data in the packet associated to
- * *skb* by *len_diff*, and according to the selected *mode*.
- *
- * There are two supported modes at this time:
- *
- * * **BPF_ADJ_ROOM_MAC**: Adjust room at the mac layer
- * (room space is added or removed below the layer 2 header).
- *
- * * **BPF_ADJ_ROOM_NET**: Adjust room at the network layer
- * (room space is added or removed below the layer 3 header).
- *
- * The following flags are supported at this time:
- *
- * * **BPF_F_ADJ_ROOM_FIXED_GSO**: Do not adjust gso_size.
- * Adjusting mss in this way is not allowed for datagrams.
- *
- * * **BPF_F_ADJ_ROOM_ENCAP_L3_IPV4**,
- * **BPF_F_ADJ_ROOM_ENCAP_L3_IPV6**:
- * Any new space is reserved to hold a tunnel header.
- * Configure skb offsets and other fields accordingly.
- *
- * * **BPF_F_ADJ_ROOM_ENCAP_L4_GRE**,
- * **BPF_F_ADJ_ROOM_ENCAP_L4_UDP**:
- * Use with ENCAP_L3 flags to further specify the tunnel type.
- *
- * * **BPF_F_ADJ_ROOM_ENCAP_L2**\ (*len*):
- * Use with ENCAP_L3/L4 flags to further specify the tunnel
- * type; *len* is the length of the inner MAC header.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_redirect_map(struct bpf_map *map, u32 key, u64 flags)
- * Description
- * Redirect the packet to the endpoint referenced by *map* at
- * index *key*. Depending on its type, this *map* can contain
- * references to net devices (for forwarding packets through other
- * ports), or to CPUs (for redirecting XDP frames to another CPU;
- * but this is only implemented for native XDP (with driver
- * support) as of this writing).
- *
- * The lower two bits of *flags* are used as the return code if
- * the map lookup fails. This is so that the return value can be
- * one of the XDP program return codes up to XDP_TX, as chosen by
- * the caller. Any higher bits in the *flags* argument must be
- * unset.
- *
- * When used to redirect packets to net devices, this helper
- * provides a high performance increase over **bpf_redirect**\ ().
- * This is due to various implementation details of the underlying
- * mechanisms, one of which is the fact that **bpf_redirect_map**\
- * () tries to send packet as a "bulk" to the device.
- * Return
- * **XDP_REDIRECT** on success, or **XDP_ABORTED** on error.
- *
- * int bpf_sk_redirect_map(struct bpf_map *map, u32 key, u64 flags)
- * Description
- * Redirect the packet to the socket referenced by *map* (of type
- * **BPF_MAP_TYPE_SOCKMAP**) at index *key*. Both ingress and
- * egress interfaces can be used for redirection. The
- * **BPF_F_INGRESS** value in *flags* is used to make the
- * distinction (ingress path is selected if the flag is present,
- * egress path otherwise). This is the only flag supported for now.
- * Return
- * **SK_PASS** on success, or **SK_DROP** on error.
- *
- * int bpf_sock_map_update(struct bpf_sock_ops *skops, struct bpf_map *map, void *key, u64 flags)
- * Description
- * Add an entry to, or update a *map* referencing sockets. The
- * *skops* is used as a new value for the entry associated to
- * *key*. *flags* is one of:
- *
- * **BPF_NOEXIST**
- * The entry for *key* must not exist in the map.
- * **BPF_EXIST**
- * The entry for *key* must already exist in the map.
- * **BPF_ANY**
- * No condition on the existence of the entry for *key*.
- *
- * If the *map* has eBPF programs (parser and verdict), those will
- * be inherited by the socket being added. If the socket is
- * already attached to eBPF programs, this results in an error.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_xdp_adjust_meta(struct xdp_buff *xdp_md, int delta)
- * Description
- * Adjust the address pointed by *xdp_md*\ **->data_meta** by
- * *delta* (which can be positive or negative). Note that this
- * operation modifies the address stored in *xdp_md*\ **->data**,
- * so the latter must be loaded only after the helper has been
- * called.
- *
- * The use of *xdp_md*\ **->data_meta** is optional and programs
- * are not required to use it. The rationale is that when the
- * packet is processed with XDP (e.g. as DoS filter), it is
- * possible to push further meta data along with it before passing
- * to the stack, and to give the guarantee that an ingress eBPF
- * program attached as a TC classifier on the same device can pick
- * this up for further post-processing. Since TC works with socket
- * buffers, it remains possible to set from XDP the **mark** or
- * **priority** pointers, or other pointers for the socket buffer.
- * Having this scratch space generic and programmable allows for
- * more flexibility as the user is free to store whatever meta
- * data they need.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_perf_event_read_value(struct bpf_map *map, u64 flags, struct bpf_perf_event_value *buf, u32 buf_size)
- * Description
- * Read the value of a perf event counter, and store it into *buf*
- * of size *buf_size*. This helper relies on a *map* of type
- * **BPF_MAP_TYPE_PERF_EVENT_ARRAY**. The nature of the perf event
- * counter is selected when *map* is updated with perf event file
- * descriptors. The *map* is an array whose size is the number of
- * available CPUs, and each cell contains a value relative to one
- * CPU. The value to retrieve is indicated by *flags*, that
- * contains the index of the CPU to look up, masked with
- * **BPF_F_INDEX_MASK**. Alternatively, *flags* can be set to
- * **BPF_F_CURRENT_CPU** to indicate that the value for the
- * current CPU should be retrieved.
- *
- * This helper behaves in a way close to
- * **bpf_perf_event_read**\ () helper, save that instead of
- * just returning the value observed, it fills the *buf*
- * structure. This allows for additional data to be retrieved: in
- * particular, the enabled and running times (in *buf*\
- * **->enabled** and *buf*\ **->running**, respectively) are
- * copied. In general, **bpf_perf_event_read_value**\ () is
- * recommended over **bpf_perf_event_read**\ (), which has some
- * ABI issues and provides fewer functionalities.
- *
- * These values are interesting, because hardware PMU (Performance
- * Monitoring Unit) counters are limited resources. When there are
- * more PMU based perf events opened than available counters,
- * kernel will multiplex these events so each event gets certain
- * percentage (but not all) of the PMU time. In case that
- * multiplexing happens, the number of samples or counter value
- * will not reflect the case compared to when no multiplexing
- * occurs. This makes comparison between different runs difficult.
- * Typically, the counter value should be normalized before
- * comparing to other experiments. The usual normalization is done
- * as follows.
- *
- * ::
- *
- * normalized_counter = counter * t_enabled / t_running
- *
- * Where t_enabled is the time enabled for event and t_running is
- * the time running for event since last normalization. The
- * enabled and running times are accumulated since the perf event
- * open. To achieve scaling factor between two invocations of an
- * eBPF program, users can can use CPU id as the key (which is
- * typical for perf array usage model) to remember the previous
- * value and do the calculation inside the eBPF program.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_perf_prog_read_value(struct bpf_perf_event_data *ctx, struct bpf_perf_event_value *buf, u32 buf_size)
- * Description
- * For en eBPF program attached to a perf event, retrieve the
- * value of the event counter associated to *ctx* and store it in
- * the structure pointed by *buf* and of size *buf_size*. Enabled
- * and running times are also stored in the structure (see
- * description of helper **bpf_perf_event_read_value**\ () for
- * more details).
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_getsockopt(struct bpf_sock_ops *bpf_socket, int level, int optname, char *optval, int optlen)
- * Description
- * Emulate a call to **getsockopt()** on the socket associated to
- * *bpf_socket*, which must be a full socket. The *level* at
- * which the option resides and the name *optname* of the option
- * must be specified, see **getsockopt(2)** for more information.
- * The retrieved value is stored in the structure pointed by
- * *opval* and of length *optlen*.
- *
- * This helper actually implements a subset of **getsockopt()**.
- * It supports the following *level*\ s:
- *
- * * **IPPROTO_TCP**, which supports *optname*
- * **TCP_CONGESTION**.
- * * **IPPROTO_IP**, which supports *optname* **IP_TOS**.
- * * **IPPROTO_IPV6**, which supports *optname* **IPV6_TCLASS**.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_override_return(struct pt_regs *regs, u64 rc)
- * Description
- * Used for error injection, this helper uses kprobes to override
- * the return value of the probed function, and to set it to *rc*.
- * The first argument is the context *regs* on which the kprobe
- * works.
- *
- * This helper works by setting setting the PC (program counter)
- * to an override function which is run in place of the original
- * probed function. This means the probed function is not run at
- * all. The replacement function just returns with the required
- * value.
- *
- * This helper has security implications, and thus is subject to
- * restrictions. It is only available if the kernel was compiled
- * with the **CONFIG_BPF_KPROBE_OVERRIDE** configuration
- * option, and in this case it only works on functions tagged with
- * **ALLOW_ERROR_INJECTION** in the kernel code.
- *
- * Also, the helper is only available for the architectures having
- * the CONFIG_FUNCTION_ERROR_INJECTION option. As of this writing,
- * x86 architecture is the only one to support this feature.
- * Return
- * 0
- *
- * int bpf_sock_ops_cb_flags_set(struct bpf_sock_ops *bpf_sock, int argval)
- * Description
- * Attempt to set the value of the **bpf_sock_ops_cb_flags** field
- * for the full TCP socket associated to *bpf_sock_ops* to
- * *argval*.
- *
- * The primary use of this field is to determine if there should
- * be calls to eBPF programs of type
- * **BPF_PROG_TYPE_SOCK_OPS** at various points in the TCP
- * code. A program of the same type can change its value, per
- * connection and as necessary, when the connection is
- * established. This field is directly accessible for reading, but
- * this helper must be used for updates in order to return an
- * error if an eBPF program tries to set a callback that is not
- * supported in the current kernel.
- *
- * *argval* is a flag array which can combine these flags:
- *
- * * **BPF_SOCK_OPS_RTO_CB_FLAG** (retransmission time out)
- * * **BPF_SOCK_OPS_RETRANS_CB_FLAG** (retransmission)
- * * **BPF_SOCK_OPS_STATE_CB_FLAG** (TCP state change)
- * * **BPF_SOCK_OPS_RTT_CB_FLAG** (every RTT)
- *
- * Therefore, this function can be used to clear a callback flag by
- * setting the appropriate bit to zero. e.g. to disable the RTO
- * callback:
- *
- * **bpf_sock_ops_cb_flags_set(bpf_sock,**
- * **bpf_sock->bpf_sock_ops_cb_flags & ~BPF_SOCK_OPS_RTO_CB_FLAG)**
- *
- * Here are some examples of where one could call such eBPF
- * program:
- *
- * * When RTO fires.
- * * When a packet is retransmitted.
- * * When the connection terminates.
- * * When a packet is sent.
- * * When a packet is received.
- * Return
- * Code **-EINVAL** if the socket is not a full TCP socket;
- * otherwise, a positive number containing the bits that could not
- * be set is returned (which comes down to 0 if all bits were set
- * as required).
- *
- * int bpf_msg_redirect_map(struct sk_msg_buff *msg, struct bpf_map *map, u32 key, u64 flags)
- * Description
- * This helper is used in programs implementing policies at the
- * socket level. If the message *msg* is allowed to pass (i.e. if
- * the verdict eBPF program returns **SK_PASS**), redirect it to
- * the socket referenced by *map* (of type
- * **BPF_MAP_TYPE_SOCKMAP**) at index *key*. Both ingress and
- * egress interfaces can be used for redirection. The
- * **BPF_F_INGRESS** value in *flags* is used to make the
- * distinction (ingress path is selected if the flag is present,
- * egress path otherwise). This is the only flag supported for now.
- * Return
- * **SK_PASS** on success, or **SK_DROP** on error.
- *
- * int bpf_msg_apply_bytes(struct sk_msg_buff *msg, u32 bytes)
- * Description
- * For socket policies, apply the verdict of the eBPF program to
- * the next *bytes* (number of bytes) of message *msg*.
- *
- * For example, this helper can be used in the following cases:
- *
- * * A single **sendmsg**\ () or **sendfile**\ () system call
- * contains multiple logical messages that the eBPF program is
- * supposed to read and for which it should apply a verdict.
- * * An eBPF program only cares to read the first *bytes* of a
- * *msg*. If the message has a large payload, then setting up
- * and calling the eBPF program repeatedly for all bytes, even
- * though the verdict is already known, would create unnecessary
- * overhead.
- *
- * When called from within an eBPF program, the helper sets a
- * counter internal to the BPF infrastructure, that is used to
- * apply the last verdict to the next *bytes*. If *bytes* is
- * smaller than the current data being processed from a
- * **sendmsg**\ () or **sendfile**\ () system call, the first
- * *bytes* will be sent and the eBPF program will be re-run with
- * the pointer for start of data pointing to byte number *bytes*
- * **+ 1**. If *bytes* is larger than the current data being
- * processed, then the eBPF verdict will be applied to multiple
- * **sendmsg**\ () or **sendfile**\ () calls until *bytes* are
- * consumed.
- *
- * Note that if a socket closes with the internal counter holding
- * a non-zero value, this is not a problem because data is not
- * being buffered for *bytes* and is sent as it is received.
- * Return
- * 0
- *
- * int bpf_msg_cork_bytes(struct sk_msg_buff *msg, u32 bytes)
- * Description
- * For socket policies, prevent the execution of the verdict eBPF
- * program for message *msg* until *bytes* (byte number) have been
- * accumulated.
- *
- * This can be used when one needs a specific number of bytes
- * before a verdict can be assigned, even if the data spans
- * multiple **sendmsg**\ () or **sendfile**\ () calls. The extreme
- * case would be a user calling **sendmsg**\ () repeatedly with
- * 1-byte long message segments. Obviously, this is bad for
- * performance, but it is still valid. If the eBPF program needs
- * *bytes* bytes to validate a header, this helper can be used to
- * prevent the eBPF program to be called again until *bytes* have
- * been accumulated.
- * Return
- * 0
- *
- * int bpf_msg_pull_data(struct sk_msg_buff *msg, u32 start, u32 end, u64 flags)
- * Description
- * For socket policies, pull in non-linear data from user space
- * for *msg* and set pointers *msg*\ **->data** and *msg*\
- * **->data_end** to *start* and *end* bytes offsets into *msg*,
- * respectively.
- *
- * If a program of type **BPF_PROG_TYPE_SK_MSG** is run on a
- * *msg* it can only parse data that the (**data**, **data_end**)
- * pointers have already consumed. For **sendmsg**\ () hooks this
- * is likely the first scatterlist element. But for calls relying
- * on the **sendpage** handler (e.g. **sendfile**\ ()) this will
- * be the range (**0**, **0**) because the data is shared with
- * user space and by default the objective is to avoid allowing
- * user space to modify data while (or after) eBPF verdict is
- * being decided. This helper can be used to pull in data and to
- * set the start and end pointer to given values. Data will be
- * copied if necessary (i.e. if data was not linear and if start
- * and end pointers do not point to the same chunk).
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- *
- * All values for *flags* are reserved for future usage, and must
- * be left at zero.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_bind(struct bpf_sock_addr *ctx, struct sockaddr *addr, int addr_len)
- * Description
- * Bind the socket associated to *ctx* to the address pointed by
- * *addr*, of length *addr_len*. This allows for making outgoing
- * connection from the desired IP address, which can be useful for
- * example when all processes inside a cgroup should use one
- * single IP address on a host that has multiple IP configured.
- *
- * This helper works for IPv4 and IPv6, TCP and UDP sockets. The
- * domain (*addr*\ **->sa_family**) must be **AF_INET** (or
- * **AF_INET6**). Looking for a free port to bind to can be
- * expensive, therefore binding to port is not permitted by the
- * helper: *addr*\ **->sin_port** (or **sin6_port**, respectively)
- * must be set to zero.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_xdp_adjust_tail(struct xdp_buff *xdp_md, int delta)
- * Description
- * Adjust (move) *xdp_md*\ **->data_end** by *delta* bytes. It is
- * only possible to shrink the packet as of this writing,
- * therefore *delta* must be a negative integer.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_skb_get_xfrm_state(struct sk_buff *skb, u32 index, struct bpf_xfrm_state *xfrm_state, u32 size, u64 flags)
- * Description
- * Retrieve the XFRM state (IP transform framework, see also
- * **ip-xfrm(8)**) at *index* in XFRM "security path" for *skb*.
- *
- * The retrieved value is stored in the **struct bpf_xfrm_state**
- * pointed by *xfrm_state* and of length *size*.
- *
- * All values for *flags* are reserved for future usage, and must
- * be left at zero.
- *
- * This helper is available only if the kernel was compiled with
- * **CONFIG_XFRM** configuration option.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_get_stack(struct pt_regs *regs, void *buf, u32 size, u64 flags)
- * Description
- * Return a user or a kernel stack in bpf program provided buffer.
- * To achieve this, the helper needs *ctx*, which is a pointer
- * to the context on which the tracing program is executed.
- * To store the stacktrace, the bpf program provides *buf* with
- * a nonnegative *size*.
- *
- * The last argument, *flags*, holds the number of stack frames to
- * skip (from 0 to 255), masked with
- * **BPF_F_SKIP_FIELD_MASK**. The next bits can be used to set
- * the following flags:
- *
- * **BPF_F_USER_STACK**
- * Collect a user space stack instead of a kernel stack.
- * **BPF_F_USER_BUILD_ID**
- * Collect buildid+offset instead of ips for user stack,
- * only valid if **BPF_F_USER_STACK** is also specified.
- *
- * **bpf_get_stack**\ () can collect up to
- * **PERF_MAX_STACK_DEPTH** both kernel and user frames, subject
- * to sufficient large buffer size. Note that
- * this limit can be controlled with the **sysctl** program, and
- * that it should be manually increased in order to profile long
- * user stacks (such as stacks for Java programs). To do so, use:
- *
- * ::
- *
- * # sysctl kernel.perf_event_max_stack=<new value>
- * Return
- * A non-negative value equal to or less than *size* on success,
- * or a negative error in case of failure.
- *
- * int bpf_skb_load_bytes_relative(const struct sk_buff *skb, u32 offset, void *to, u32 len, u32 start_header)
- * Description
- * This helper is similar to **bpf_skb_load_bytes**\ () in that
- * it provides an easy way to load *len* bytes from *offset*
- * from the packet associated to *skb*, into the buffer pointed
- * by *to*. The difference to **bpf_skb_load_bytes**\ () is that
- * a fifth argument *start_header* exists in order to select a
- * base offset to start from. *start_header* can be one of:
- *
- * **BPF_HDR_START_MAC**
- * Base offset to load data from is *skb*'s mac header.
- * **BPF_HDR_START_NET**
- * Base offset to load data from is *skb*'s network header.
- *
- * In general, "direct packet access" is the preferred method to
- * access packet data, however, this helper is in particular useful
- * in socket filters where *skb*\ **->data** does not always point
- * to the start of the mac header and where "direct packet access"
- * is not available.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_fib_lookup(void *ctx, struct bpf_fib_lookup *params, int plen, u32 flags)
- * Description
- * Do FIB lookup in kernel tables using parameters in *params*.
- * If lookup is successful and result shows packet is to be
- * forwarded, the neighbor tables are searched for the nexthop.
- * If successful (ie., FIB lookup shows forwarding and nexthop
- * is resolved), the nexthop address is returned in ipv4_dst
- * or ipv6_dst based on family, smac is set to mac address of
- * egress device, dmac is set to nexthop mac address, rt_metric
- * is set to metric from route (IPv4/IPv6 only), and ifindex
- * is set to the device index of the nexthop from the FIB lookup.
- *
- * *plen* argument is the size of the passed in struct.
- * *flags* argument can be a combination of one or more of the
- * following values:
- *
- * **BPF_FIB_LOOKUP_DIRECT**
- * Do a direct table lookup vs full lookup using FIB
- * rules.
- * **BPF_FIB_LOOKUP_OUTPUT**
- * Perform lookup from an egress perspective (default is
- * ingress).
- *
- * *ctx* is either **struct xdp_md** for XDP programs or
- * **struct sk_buff** tc cls_act programs.
- * Return
- * * < 0 if any input argument is invalid
- * * 0 on success (packet is forwarded, nexthop neighbor exists)
- * * > 0 one of **BPF_FIB_LKUP_RET_** codes explaining why the
- * packet is not forwarded or needs assist from full stack
- *
- * int bpf_sock_hash_update(struct bpf_sock_ops_kern *skops, struct bpf_map *map, void *key, u64 flags)
- * Description
- * Add an entry to, or update a sockhash *map* referencing sockets.
- * The *skops* is used as a new value for the entry associated to
- * *key*. *flags* is one of:
- *
- * **BPF_NOEXIST**
- * The entry for *key* must not exist in the map.
- * **BPF_EXIST**
- * The entry for *key* must already exist in the map.
- * **BPF_ANY**
- * No condition on the existence of the entry for *key*.
- *
- * If the *map* has eBPF programs (parser and verdict), those will
- * be inherited by the socket being added. If the socket is
- * already attached to eBPF programs, this results in an error.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_msg_redirect_hash(struct sk_msg_buff *msg, struct bpf_map *map, void *key, u64 flags)
- * Description
- * This helper is used in programs implementing policies at the
- * socket level. If the message *msg* is allowed to pass (i.e. if
- * the verdict eBPF program returns **SK_PASS**), redirect it to
- * the socket referenced by *map* (of type
- * **BPF_MAP_TYPE_SOCKHASH**) using hash *key*. Both ingress and
- * egress interfaces can be used for redirection. The
- * **BPF_F_INGRESS** value in *flags* is used to make the
- * distinction (ingress path is selected if the flag is present,
- * egress path otherwise). This is the only flag supported for now.
- * Return
- * **SK_PASS** on success, or **SK_DROP** on error.
- *
- * int bpf_sk_redirect_hash(struct sk_buff *skb, struct bpf_map *map, void *key, u64 flags)
- * Description
- * This helper is used in programs implementing policies at the
- * skb socket level. If the sk_buff *skb* is allowed to pass (i.e.
- * if the verdeict eBPF program returns **SK_PASS**), redirect it
- * to the socket referenced by *map* (of type
- * **BPF_MAP_TYPE_SOCKHASH**) using hash *key*. Both ingress and
- * egress interfaces can be used for redirection. The
- * **BPF_F_INGRESS** value in *flags* is used to make the
- * distinction (ingress path is selected if the flag is present,
- * egress otherwise). This is the only flag supported for now.
- * Return
- * **SK_PASS** on success, or **SK_DROP** on error.
- *
- * int bpf_lwt_push_encap(struct sk_buff *skb, u32 type, void *hdr, u32 len)
- * Description
- * Encapsulate the packet associated to *skb* within a Layer 3
- * protocol header. This header is provided in the buffer at
- * address *hdr*, with *len* its size in bytes. *type* indicates
- * the protocol of the header and can be one of:
- *
- * **BPF_LWT_ENCAP_SEG6**
- * IPv6 encapsulation with Segment Routing Header
- * (**struct ipv6_sr_hdr**). *hdr* only contains the SRH,
- * the IPv6 header is computed by the kernel.
- * **BPF_LWT_ENCAP_SEG6_INLINE**
- * Only works if *skb* contains an IPv6 packet. Insert a
- * Segment Routing Header (**struct ipv6_sr_hdr**) inside
- * the IPv6 header.
- * **BPF_LWT_ENCAP_IP**
- * IP encapsulation (GRE/GUE/IPIP/etc). The outer header
- * must be IPv4 or IPv6, followed by zero or more
- * additional headers, up to **LWT_BPF_MAX_HEADROOM**
- * total bytes in all prepended headers. Please note that
- * if **skb_is_gso**\ (*skb*) is true, no more than two
- * headers can be prepended, and the inner header, if
- * present, should be either GRE or UDP/GUE.
- *
- * **BPF_LWT_ENCAP_SEG6**\ \* types can be called by BPF programs
- * of type **BPF_PROG_TYPE_LWT_IN**; **BPF_LWT_ENCAP_IP** type can
- * be called by bpf programs of types **BPF_PROG_TYPE_LWT_IN** and
- * **BPF_PROG_TYPE_LWT_XMIT**.
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers
- * previously done by the verifier are invalidated and must be
- * performed again, if the helper is used in combination with
- * direct packet access.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_lwt_seg6_store_bytes(struct sk_buff *skb, u32 offset, const void *from, u32 len)
- * Description
- * Store *len* bytes from address *from* into the packet
- * associated to *skb*, at *offset*. Only the flags, tag and TLVs
- * inside the outermost IPv6 Segment Routing Header can be
- * modified through this helper.
- *
- * A call to this helper is susceptible to change the underlying

- * Description
- * Adjust the size allocated to TLVs in the outermost IPv6
- * Segment Routing Header contained in the packet associated to
- * *skb*, at position *offset* by *delta* bytes. Only offsets
- * after the segments are accepted. *delta* can be as well
- * positive (growing) as negative (shrinking).
- *
- * A call to this helper is susceptible to change the underlying
- * packet buffer. Therefore, at load time, all checks on pointers

- *
- * int bpf_lwt_seg6_action(struct sk_buff *skb, u32 action, void *param, u32 param_len)
- * Description
- * Apply an IPv6 Segment Routing action of type *action* to the
- * packet associated to *skb*. Each action takes a parameter
- * contained at address *param*, and of length *param_len* bytes.
- * *action* can be one of:
- *
- * **SEG6_LOCAL_ACTION_END_X**
- * End.X action: Endpoint with Layer-3 cross-connect.

- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_rc_repeat(void *ctx)
- * Description
- * This helper is used in programs implementing IR decoding, to
- * report a successfully decoded repeat key message. This delays
- * the generation of a key up event for previously generated
- * key down event.
- *
- * Some IR protocols like NEC have a special IR message for
- * repeating last button, for when a button is held down.
- *
- * The *ctx* should point to the lirc sample as passed into
- * the program.
- *
- * This helper is only available is the kernel was compiled with
- * the **CONFIG_BPF_LIRC_MODE2** configuration option set to
- * "**y**".
- * Return
- * 0
- *
- * int bpf_rc_keydown(void *ctx, u32 protocol, u64 scancode, u32 toggle)
- * Description
- * This helper is used in programs implementing IR decoding, to
- * report a successfully decoded key press with *scancode*,
- * *toggle* value in the given *protocol*. The scancode will be
- * translated to a keycode using the rc keymap, and reported as
- * an input key down event. After a period a key up event is
- * generated. This period can be extended by calling either
- * **bpf_rc_keydown**\ () again with the same values, or calling
- * **bpf_rc_repeat**\ ().
- *
- * Some protocols include a toggle bit, in case the button was
- * released and pressed again between consecutive scancodes.
- *
- * The *ctx* should point to the lirc sample as passed into
- * the program.
- *
- * The *protocol* is the decoded protocol number (see
- * **enum rc_proto** for some predefined values).
- *
- * This helper is only available is the kernel was compiled with
- * the **CONFIG_BPF_LIRC_MODE2** configuration option set to
- * "**y**".
- * Return
- * 0
- *
- * u64 bpf_skb_cgroup_id(struct sk_buff *skb)
- * Description
- * Return the cgroup v2 id of the socket associated with the *skb*.
- * This is roughly similar to the **bpf_get_cgroup_classid**\ ()
- * helper for cgroup v1 by providing a tag resp. identifier that
- * can be matched on or used for map lookups e.g. to implement
- * policy. The cgroup v2 id of a given path in the hierarchy is
- * exposed in user space through the f_handle API in order to get
- * to the same 64-bit id.
- *
- * This helper can be used on TC egress path, but not on ingress,
- * and is available only if the kernel was compiled with the
- * **CONFIG_SOCK_CGROUP_DATA** configuration option.
- * Return
- * The id is returned or 0 in case the id could not be retrieved.
- *
- * u64 bpf_get_current_cgroup_id(void)
- * Return
- * A 64-bit integer containing the current cgroup id based
- * on the cgroup within which the current task is running.
- *
- * void *bpf_get_local_storage(void *map, u64 flags)
- * Description
- * Get the pointer to the local storage area.
- * The type and the size of the local storage is defined
- * by the *map* argument.
- * The *flags* meaning is specific for each map type,
- * and has to be 0 for cgroup local storage.
- *
- * Depending on the BPF program type, a local storage area
- * can be shared between multiple instances of the BPF program,
- * running simultaneously.
- *
- * A user should care about the synchronization by himself.
- * For example, by using the **BPF_STX_XADD** instruction to alter
- * the shared data.
- * Return
- * A pointer to the local storage area.
- *
- * int bpf_sk_select_reuseport(struct sk_reuseport_md *reuse, struct bpf_map *map, void *key, u64 flags)
- * Description
- * Select a **SO_REUSEPORT** socket from a
- * **BPF_MAP_TYPE_REUSEPORT_ARRAY** *map*.
- * It checks the selected socket is matching the incoming
- * request in the socket buffer.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * u64 bpf_skb_ancestor_cgroup_id(struct sk_buff *skb, int ancestor_level)
- * Description
- * Return id of cgroup v2 that is ancestor of cgroup associated
- * with the *skb* at the *ancestor_level*. The root cgroup is at
- * *ancestor_level* zero and each step down the hierarchy
- * increments the level. If *ancestor_level* == level of cgroup
- * associated with *skb*, then return value will be same as that
- * of **bpf_skb_cgroup_id**\ ().
- *
- * The helper is useful to implement policies based on cgroups
- * that are upper in hierarchy than immediate cgroup associated
- * with *skb*.
- *
- * The format of returned id and helper limitations are same as in
- * **bpf_skb_cgroup_id**\ ().
- * Return
- * The id is returned or 0 in case the id could not be retrieved.
- *
- * struct bpf_sock *bpf_sk_lookup_tcp(void *ctx, struct bpf_sock_tuple *tuple, u32 tuple_size, u64 netns, u64 flags)
- * Description
- * Look for TCP socket matching *tuple*, optionally in a child
- * network namespace *netns*. The return value must be checked,
- * and if non-**NULL**, released via **bpf_sk_release**\ ().
- *
- * The *ctx* should point to the context of the program, such as
- * the skb or socket (depending on the hook in use). This is used
- * to determine the base network namespace for the lookup.
- *
- * *tuple_size* must be one of:
- *
- * **sizeof**\ (*tuple*\ **->ipv4**)
- * Look for an IPv4 socket.
- * **sizeof**\ (*tuple*\ **->ipv6**)
- * Look for an IPv6 socket.
- *
- * If the *netns* is a negative signed 32-bit integer, then the
- * socket lookup table in the netns associated with the *ctx* will
- * will be used. For the TC hooks, this is the netns of the device
- * in the skb. For socket hooks, this is the netns of the socket.
- * If *netns* is any other signed 32-bit value greater than or
- * equal to zero then it specifies the ID of the netns relative to
- * the netns associated with the *ctx*. *netns* values beyond the
- * range of 32-bit integers are reserved for future use.
- *
- * All values for *flags* are reserved for future usage, and must
- * be left at zero.
- *
- * This helper is available only if the kernel was compiled with
- * **CONFIG_NET** configuration option.
- * Return
- * Pointer to **struct bpf_sock**, or **NULL** in case of failure.
- * For sockets with reuseport option, the **struct bpf_sock**
- * result is from *reuse*\ **->socks**\ [] using the hash of the
- * tuple.
- *
- * struct bpf_sock *bpf_sk_lookup_udp(void *ctx, struct bpf_sock_tuple *tuple, u32 tuple_size, u64 netns, u64 flags)
- * Description
- * Look for UDP socket matching *tuple*, optionally in a child
- * network namespace *netns*. The return value must be checked,
- * and if non-**NULL**, released via **bpf_sk_release**\ ().
- *
- * The *ctx* should point to the context of the program, such as

- * **sizeof**\ (*tuple*\ **->ipv4**)
- * Look for an IPv4 socket.
- * **sizeof**\ (*tuple*\ **->ipv6**)
- * Look for an IPv6 socket.
- *
- * If the *netns* is a negative signed 32-bit integer, then the
- * socket lookup table in the netns associated with the *ctx* will
- * will be used. For the TC hooks, this is the netns of the device
- * in the skb. For socket hooks, this is the netns of the socket.
- * If *netns* is any other signed 32-bit value greater than or
- * equal to zero then it specifies the ID of the netns relative to

- *
- * This helper is available only if the kernel was compiled with

- * For sockets with reuseport option, the **struct bpf_sock**
- * result is from *reuse*\ **->socks**\ [] using the hash of the
- * tuple.
- *
- * int bpf_sk_release(struct bpf_sock *sock)
- * Description
- * Release the reference held by *sock*. *sock* must be a
- * non-**NULL** pointer that was returned from
- * **bpf_sk_lookup_xxx**\ ().
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_map_push_elem(struct bpf_map *map, const void *value, u64 flags)
- * Description
- * Push an element *value* in *map*. *flags* is one of:
- *
- * **BPF_EXIST**
- * If the queue/stack is full, the oldest element is
- * removed to make room for this.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_map_pop_elem(struct bpf_map *map, void *value)
- * Description

- * int bpf_msg_push_data(struct sk_buff *skb, u32 start, u32 len, u64 flags)
- * Description
- * For socket policies, insert *len* bytes into *msg* at offset
- * *start*.
- *
- * If a program of type **BPF_PROG_TYPE_SK_MSG** is run on a
- * *msg* it may want to insert metadata or options into the *msg*.
- * This can later be read and used by any of the lower layer BPF
- * hooks.
- *
- * This helper may fail if under memory pressure (a malloc
- * fails) in these cases BPF programs will get an appropriate
- * error and BPF programs will need to handle them.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_msg_pop_data(struct sk_msg_buff *msg, u32 start, u32 pop, u64 flags)
- * Description
- * Will remove *pop* bytes from a *msg* starting at byte *start*.
- * This may result in **ENOMEM** errors under certain situations if
- * an allocation and copy are required due to a full ring buffer.
- * However, the helper will try to avoid doing the allocation
- * if possible. Other errors can occur if input parameters are
- * invalid either due to *start* byte not being valid part of *msg*
- * payload and/or *pop* value being to large.
- * Return
- * 0 on success, or a negative error in case of failure.
- *
- * int bpf_rc_pointer_rel(void *ctx, s32 rel_x, s32 rel_y)
- * Description
- * This helper is used in programs implementing IR decoding, to
- * report a successfully decoded pointer movement.
- *
- * The *ctx* should point to the lirc sample as passed into
- * the program.
- *
- * This helper is only available is the kernel was compiled with
- * the **CONFIG_BPF_LIRC_MODE2** configuration option set to
- * "**y**".
- * Return
- * 0
- *
- * int bpf_spin_lock(struct bpf_spin_lock *lock)
- * Description
- * Acquire a spinlock represented by the pointer *lock*, which is
- * stored as part of a value of a map. Taking the lock allows to
- * safely update the rest of the fields in that value. The
- * spinlock can (and must) later be released with a call to
- * **bpf_spin_unlock**\ (\ *lock*\ ).
- *
- * Spinlocks in BPF programs come with a number of restrictions
- * and constraints:
- *
- * * **bpf_spin_lock** objects are only allowed inside maps of
- * types **BPF_MAP_TYPE_HASH** and **BPF_MAP_TYPE_ARRAY** (this
- * list could be extended in the future).
- * * BTF description of the map is mandatory.
- * * The BPF program can take ONE lock at a time, since taking two
- * or more could cause dead locks.
- * * Only one **struct bpf_spin_lock** is allowed per map element.
- * * When the lock is taken, calls (either BPF to BPF or helpers)
- * are not allowed.
- * * The **BPF_LD_ABS** and **BPF_LD_IND** instructions are not
- * allowed inside a spinlock-ed region.
- * * The BPF program MUST call **bpf_spin_unlock**\ () to release
- * the lock, on all execution paths, before it returns.
- * * The BPF program can access **struct bpf_spin_lock** only via
- * the **bpf_spin_lock**\ () and **bpf_spin_unlock**\ ()
- * helpers. Loading or storing data into the **struct
- * bpf_spin_lock** *lock*\ **;** field of a map is not allowed.
- * * To use the **bpf_spin_lock**\ () helper, the BTF description
- * of the map value must be a struct and have **struct
- * bpf_spin_lock** *anyname*\ **;** field at the top level.
- * Nested lock inside another struct is not allowed.
- * * The **struct bpf_spin_lock** *lock* field in a map value must
- * be aligned on a multiple of 4 bytes in that value.
- * * Syscall with command **BPF_MAP_LOOKUP_ELEM** does not copy
- * the **bpf_spin_lock** field to user space.
- * * Syscall with command **BPF_MAP_UPDATE_ELEM**, or update from
- * a BPF program, do not update the **bpf_spin_lock** field.
- * * **bpf_spin_lock** cannot be on the stack or inside a
- * networking packet (it can only be inside of a map values).
- * * **bpf_spin_lock** is available to root only.
- * * Tracing programs and socket filter programs cannot use
- * **bpf_spin_lock**\ () due to insufficient preemption checks
- * (but this may change in the future).
- * * **bpf_spin_lock** is not allowed in inner maps of map-in-map.
- * Return
- * 0
- *
- * int bpf_spin_unlock(struct bpf_spin_lock *lock)
- * Description
- * Release the *lock* previously locked by a call to
- * **bpf_spin_lock**\ (\ *lock*\ ).
- * Return
- * 0
- *
- * struct bpf_sock *bpf_sk_fullsock(struct bpf_sock *sk)
- * Description
- * This helper gets a **struct bpf_sock** pointer such
- * that all the fields in this **bpf_sock** can be accessed.
- * Return
- * A **struct bpf_sock** pointer on success, or **NULL** in
- * case of failure.
- *
- * struct bpf_tcp_sock *bpf_tcp_sock(struct bpf_sock *sk)
- * Description
- * This helper gets a **struct bpf_tcp_sock** pointer from a
- * **struct bpf_sock** pointer.
- * Return
- * A **struct bpf_tcp_sock** pointer on success, or **NULL** in
- * case of failure.
- *
- * int bpf_skb_ecn_set_ce(struct sk_buf *skb)
- * Description
- * Set ECN (Explicit Congestion Notification) field of IP header
- * to **CE** (Congestion Encountered) if current value is **ECT**
- * (ECN Capable Transport). Otherwise, do nothing. Works with IPv6
- * and IPv4.
- * Return
- * 1 if the **CE** flag is set (either by the current helper call
- * or because it was already present), 0 if it is not set.
- *
- * struct bpf_sock *bpf_get_listener_sock(struct bpf_sock *sk)
- * Description
- * Return a **struct bpf_sock** pointer in **TCP_LISTEN** state.

- * struct bpf_sock *bpf_skc_lookup_tcp(void *ctx, struct bpf_sock_tuple *tuple, u32 tuple_size, u64 netns, u64 flags)
- * Description
- * Look for TCP socket matching *tuple*, optionally in a child
- * network namespace *netns*. The return value must be checked,
- * and if non-**NULL**, released via **bpf_sk_release**\ ().
- *
- * This function is identical to **bpf_sk_lookup_tcp**\ (), except
- * that it also returns timewait or request sockets. Use
- * **bpf_sk_fullsock**\ () or **bpf_tcp_sock**\ () to access the
- * full structure.
- *
- * This helper is available only if the kernel was compiled with
- * **CONFIG_NET** configuration option.
- * Return
- * Pointer to **struct bpf_sock**, or **NULL** in case of failure.
- * For sockets with reuseport option, the **struct bpf_sock**
- * result is from *reuse*\ **->socks**\ [] using the hash of the
- * tuple.
- *
- * int bpf_tcp_check_syncookie(struct bpf_sock *sk, void *iph, u32 iph_len, struct tcphdr *th, u32 th_len)
- * Description
- * Check whether *iph* and *th* contain a valid SYN cookie ACK for
- * the listening socket in *sk*.
- *
- * *iph* points to the start of the IPv4 or IPv6 header, while
- * *iph_len* contains **sizeof**\ (**struct iphdr**) or
- * **sizeof**\ (**struct ip6hdr**).
- *
- * *th* points to the start of the TCP header, while *th_len*
- * contains **sizeof**\ (**struct tcphdr**).

- * Description
- * Get name of sysctl in /proc/sys/ and copy it into provided by
- * program buffer *buf* of size *buf_len*.
- *
- * The buffer is always NUL terminated, unless it's zero-sized.
- *
- * If *flags* is zero, full name (e.g. "net/ipv4/tcp_mem") is
- * copied. Use **BPF_F_SYSCTL_BASE_NAME** flag to copy base name
- * only (e.g. "tcp_mem").
- * Return
- * Number of character copied (not including the trailing NUL).
- *
- * **-E2BIG** if the buffer wasn't big enough (*buf* will contain
- * truncated name in this case).
- *
- * int bpf_sysctl_get_current_value(struct bpf_sysctl *ctx, char *buf, size_t buf_len)
- * Description
- * Get current value of sysctl as it is presented in /proc/sys
- * (incl. newline, etc), and copy it as a string into provided
- * by program buffer *buf* of size *buf_len*.
- *
- * The whole value is copied, no matter what file position user
- * space issued e.g. sys_read at.
- *
- * The buffer is always NUL terminated, unless it's zero-sized.
- * Return
- * Number of character copied (not including the trailing NUL).
- *
- * **-E2BIG** if the buffer wasn't big enough (*buf* will contain
- * truncated name in this case).
- *
- * **-EINVAL** if current value was unavailable, e.g. because
- * sysctl is uninitialized and read returns -EIO for it.
- *
- * int bpf_sysctl_get_new_value(struct bpf_sysctl *ctx, char *buf, size_t buf_len)
- * Description
- * Get new value being written by user space to sysctl (before
- * the actual write happens) and copy it as a string into

- *
- * User space may write new value at file position > 0.
- *
- * The buffer is always NUL terminated, unless it's zero-sized.
- * Return
- * Number of character copied (not including the trailing NUL).
- *
- * **-E2BIG** if the buffer wasn't big enough (*buf* will contain

- *
- * int bpf_sysctl_set_new_value(struct bpf_sysctl *ctx, const char *buf, size_t buf_len)
- * Description
- * Override new value being written by user space to sysctl with
- * value provided by program in buffer *buf* of size *buf_len*.
- *
- * *buf* should contain a string in same form as provided by user
- * space on sysctl write.
- *
- * User space may write new value at file position > 0. To override
- * the whole sysctl value file position should be set to zero.
- * Return
- * 0 on success.
- *
- * **-E2BIG** if the *buf_len* is too big.

- * Description
- * Convert the initial part of the string from buffer *buf* of
- * size *buf_len* to a long integer according to the given base
- * and save the result in *res*.
- *
- * The string may begin with an arbitrary amount of white space
- * (as determined by **isspace**\ (3)) followed by a single
- * optional '**-**' sign.
- *
- * Five least significant bits of *flags* encode base, other bits
- * are currently unused.
- *
- * Base must be either 8, 10, 16 or 0 to detect it automatically
- * similar to user space **strtol**\ (3).

- *
- * void *bpf_sk_storage_get(struct bpf_map *map, struct bpf_sock *sk, void *value, u64 flags)
- * Description
- * Get a bpf-local-storage from a *sk*.
- *
- * Logically, it could be thought of getting the value from
- * a *map* with *sk* as the **key**. From this
- * perspective, the usage is not much different from
- * **bpf_map_lookup_elem**\ (*map*, **&**\ *sk*) except this
- * helper enforces the key must be a full socket and the map must
- * be a **BPF_MAP_TYPE_SK_STORAGE** also.
- *
- * Underneath, the value is stored locally at *sk* instead of
- * the *map*. The *map* is used as the bpf-local-storage
- * "type". The bpf-local-storage "type" (i.e. the *map*) is
- * searched against all bpf-local-storages residing at *sk*.
- *
- * An optional *flags* (**BPF_SK_STORAGE_GET_F_CREATE**) can be
- * used such that a new bpf-local-storage will be
- * created if one does not exist. *value* can be used
- * together with **BPF_SK_STORAGE_GET_F_CREATE** to specify
- * the initial value of a bpf-local-storage. If *value* is
- * **NULL**, the new bpf-local-storage will be zero initialized.
- * Return
- * A bpf-local-storage pointer is returned on success.
- *
- * **NULL** if not found or there was an error in adding
- * a new bpf-local-storage.
- *
- * int bpf_sk_storage_delete(struct bpf_map *map, struct bpf_sock *sk)
- * Description
- * Delete a bpf-local-storage from a *sk*.
- * Return
- * 0 on success.
- *
- * **-ENOENT** if the bpf-local-storage cannot be found.
- *
- * int bpf_send_signal(u32 sig)
- * Description
- * Send signal *sig* to the current task.
- * Return
- * 0 on success or successfully queued.
- *
- * **-EBUSY** if work queue under nmi is full.
- *
- * **-EINVAL** if *sig* is invalid.
- *
- * **-EPERM** if no permission to send the *sig*.
- *
- * **-EAGAIN** if bpf program can try again.
- *
- * s64 bpf_tcp_gen_syncookie(struct bpf_sock *sk, void *iph, u32 iph_len, struct tcphdr *th, u32 th_len)
- * Description
- * Try to issue a SYN cookie for the packet with corresponding
- * IP/TCP headers, *iph* and *th*, on the listening socket in *sk*.
- *
- * *iph* points to the start of the IPv4 or IPv6 header, while
- * *iph_len* contains **sizeof**\ (**struct iphdr**) or
- * **sizeof**\ (**struct ip6hdr**).
- *
- * *th* points to the start of the TCP header, while *th_len*
- * contains the length of the TCP header.
- *
- * Return
- * On success, lower 32 bits hold the generated SYN cookie in
- * followed by 16 bits which hold the MSS value for that cookie,
- * and the top 16 bits are unused.
- *
- * On failure, the returned value is one of the following:
- *
- * **-EINVAL** SYN cookie cannot be issued due to error
- *
- * **-ENOENT** SYN cookie should not be issued (no SYN flood)
- *
- * **-EOPNOTSUPP** kernel configuration does not enable SYN cookies
- *
- * **-EPROTONOSUPPORT** IP packet version is not 4 or 6

- * Compatibility interface for userspace libc header coordination:
- *
- * Define compatibility macros that are used to control the inclusion or
- * exclusion of UAPI structures and definitions in coordination with another
- * userspace C library.
- *
- * This header is intended to solve the problem of UAPI definitions that
- * conflict with userspace definitions. If a UAPI header has such conflicting
- * definitions then the solution is as follows:
- *
- * * Synchronize the UAPI header and the libc headers so either one can be
- * used and such that the ABI is preserved. If this is not possible then
- * no simple compatibility interface exists (you need to write translating
- * wrappers and rename things) and you can't use this interface.
- *
- * Then follow this process:
- *
- * (a) Include libc-compat.h in the UAPI header.
- * e.g. #include <linux/libc-compat.h>
- * This include must be as early as possible.
- *
- * (b) In libc-compat.h add enough code to detect that the comflicting
- * userspace libc header has been included first.
- *
- * (c) If the userspace libc header has been included first define a set of
- * guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
- * set their values to 0.
- *
- * (d) Back in the UAPI header with the conflicting definitions, guard the
- * definitions with:
- * #if __UAPI_DEF_FOO
- * ...
- * #endif
- *
- * This fixes the situation where the linux headers are included *after* the
- * libc headers. To fix the problem with the inclusion in the other order the
- * userspace libc headers must be fixed like this:
- *
- * * For all definitions that conflict with kernel definitions wrap those
- * defines in the following:
- * #if !__UAPI_DEF_FOO
- * ...
- * #endif
- *
- * This prevents the redefinition of a construct already defined by the kernel.
