+ 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
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+This is a set of utilities for Linux networking.
+
+Information:
+ https://wiki.linuxfoundation.org/networking/iproute2
+
+Download:
+ http://www.kernel.org/pub/linux/utils/net/iproute2/
+
+Stable version repository:
+ git://git.kernel.org/pub/scm/network/iproute2/iproute2.git
+
+Development repository:
+ git://git.kernel.org/pub/scm/network/iproute2/iproute2-next.git
+
+How to compile this.
+--------------------
+1. libdbm
+
+arpd needs to have the berkeleydb development libraries. For Debian
+users this is the package with a name like libdbX.X-dev.
+DBM_INCLUDE points to the directory with db_185.h which
+is the include file used by arpd to get to the old format Berkeley
+database routines. Often this is in the db-devel package.
+
+2. make
+
+The makefile will automatically build a config.mk file which
+contains definitions of libraries that may or may not be available
+on the system such as: ATM, ELF, MNL, and SELINUX.
+
+3. To make documentation, cd to doc/ directory , then
+ look at start of Makefile and set correct values for
+ PAGESIZE=a4 , ie: a4 , letter ... (string)
+ PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
+ and make there. It assumes, that latex, dvips and psnup
+ are in your path.
+
+4. This package includes matching sanitized kernel headers because
+ the build environment may not have up to date versions. See Makefile
+ if you have special requirements and need to point at different
+ kernel include files.

+Iproute2 development is closely tied to Linux kernel networking
+development. Most new features require a kernel and a utility component.
+
+Please submit both to the Linux networking mailing list
+ <netdev@vger.kernel.org>
+
+The current source for the stable version is in the git repository:
+ git://git.kernel.org/pub/scm/network/iproute2/iproute2.git
+
+The development git repository is available at the following address:
+ git://git.kernel.org/pub/scm/network/iproute2/iproute2-next.git
+
+The stable repository contains the source corresponding to the
+current code in the Linux networking tree (net), which in turn is
+aligned on the mainline Linux kernel (ie follows Linus).
+The iproute2-next repository tracks the code intended for the next
+release; it corresponds with networking development tree (net-next)
+in the kernel.

+
+This documented is slightly dated but should give you idea of how things
+work.
+
+What is it?
+-----------
+
+An extension to the filtering/classification architecture of Linux Traffic
+Control.
+Up to 2.6.8 the only action that could be "attached" to a filter was policing.
+i.e you could say something like:
+
+-----
+tc filter add dev lo parent ffff: protocol ip prio 10 u32 match ip src \
+127.0.0.1/32 flowid 1:1 police mtu 4000 rate 1500kbit burst 90k
+-----
+
+which implies "if a packet is seen on the ingress of the lo device with
+a source IP address of 127.0.0.1/32 we give it a classification id of 1:1 and
+we execute a policing action which rate limits its bandwidth utilization
+to 1.5Mbps".
+
+The new extensions allow for more than just policing actions to be added.
+They are also fully backward compatible. If you have a kernel that doesn't
+understand them, then the effect is null i.e if you have a newer tc
+but older kernel, the actions are not installed. Likewise if you
+have a newer kernel but older tc, obviously the tc will use current
+syntax which will work fine. Of course to get the required effect you need
+both newer tc and kernel. If you are reading this you have the
+right tc ;->
+
+A side effect is that we can now get stateless firewalling to work with tc.
+Essentially this is now an alternative to iptables.
+I won't go into details of my dislike for iptables at times, but
+scalability is one of the main issues; however, if you need stateful
+classification - use netfilter (for now).
+
+This stuff works on both ingress and egress qdiscs.
+
+Features
+--------
+
+1) new additional syntax and actions enabled. Note old syntax is still valid.
+
+Essentially this is still the same syntax as tc with a new construct
+"action". The syntax is of the form:
+tc filter add <DEVICE> parent 1:0 protocol ip prio 10 <Filter description>
+flowid 1:1 action <ACTION description>*
+
+You can have as many actions as you want (within sensible reasoning).
+
+In the past the only real action was the policer; i.e you could do something
+along the lines of:
+tc filter add dev lo parent ffff: protocol ip prio 10 u32 \
+match ip src 127.0.0.1/32 flowid 1:1 \
+police mtu 4000 rate 1500kbit burst 90k
+
+Although you can still use the same syntax, now you can say:
+
+tc filter add dev lo parent 1:0 protocol ip prio 10 u32 \
+match ip src 127.0.0.1/32 flowid 1:1 \
+action police mtu 4000 rate 1500kbit burst 90k
+
+" generic Actions" (gact) at the moment are:
+{ drop, pass, reclassify, continue}
+(If you have others, no listed here give me a reason and we will add them)
++drop says to drop the packet
++pass and ok (are equivalent) says to accept it
++reclassify requests for reclassification of the packet
++continue requests for next lookup to match
+
+2)In order to take advantage of some of the targets written by the
+iptables people, a classifier can have a packet being massaged by an
+iptable target. I have only tested with mangler targets up to now.
+(infact anything that is not in the mangling table is disabled right now)
+
+In terms of hooks:
+*ingress is mapped to pre-routing hook
+*egress is mapped to post-routing hook
+I don't see much value in the other hooks, if you see it and email me good
+reasons, the addition is trivial.
+
+Example syntax for iptables targets usage becomes:
+tc filter add ..... u32 <u32 syntax> action ipt -j <iptables target syntax>
+
+example:
+tc filter add dev lo parent ffff: protocol ip prio 8 u32 \
+match ip dst 127.0.0.8/32 flowid 1:12 \
+action ipt -j mark --set-mark 2
+
+NOTE: flowid 1:12 is parsed flowid 0x1:0x12. Make sure if you want flowid
+decimal 12, then use flowid 1:c.
+
+3) A feature i call pipe
+The motivation is derived from Unix pipe mechanism but applied to packets.
+Essentially take a matching packet and pass it through
+action1 | action2 | action3 etc.
+You could do something similar to this with the tc policer and the "continue"
+operator but this rather restricts it to just the policer and requires
+multiple rules (and lookups, hence quiet inefficient);
+
+as an example -- and please note that this is just an example _not_ The
+Word Youve Been Waiting For (yes i have had problems giving examples
+which ended becoming dogma in documents and people modifying them a little
+to look clever);
+
+i selected the metering rates to be small so that i can show better how
+things work.
+
+The script below does the following:
+- an incoming packet from 10.0.0.21 is first given a firewall mark of 1.
+
+- It is then metered to make sure it does not exceed its allocated rate of
+1Kbps. If it doesn't exceed rate, this is where we terminate action execution.
+
+- If it does exceed its rate, its "color" changes to a mark of 2 and it is
+then passed through a second meter.
+
+-The second meter is shared across all flows on that device [i am surpised
+that this seems to be not a well know feature of the policer; Bert was telling
+me that someone was writing a qdisc just to do sharing across multiple devices;
+it must be the summer heat again; weve had someone doing that every year around
+summer -- the key to sharing is to use a operator "index" in your policer
+rules (example "index 20"). All your rules have to use the same index to
+share.]
+
+-If the second meter is exceeded the color of the flow changes further to 3.
+
+-We then pass the packet to another meter which is shared across all devices
+in the system. If this meter is exceeded we drop the packet.
+
+Note the mark can be used further up the system to do things like policy
+or more interesting things on the egress.
+
+------------------ cut here -------------------------------
+#
+# Add an ingress qdisc on eth0
+tc qdisc add dev eth0 ingress

+#
+# first give it a mark of 1
+action ipt -j mark --set-mark 1 index 2 \
+#
+# then pass it through a policer which allows 1kbps; if the flow
+# doesn't exceed that rate, this is where we stop, if it exceeds we
+# pipe the packet to the next action

+#

+# mark it as fwmark 3 if exceeded

+
+IFB is intended to replace IMQ.
+Advantage over current IMQ; cleaner in particular in in SMP;
+with a _lot_ less code.
+
+Known IMQ/IFB USES
+------------------
+
+As far as i know the reasons listed below is why people use IMQ.
+It would be nice to know of anything else that i missed.
+
+1) qdiscs/policies that are per device as opposed to system wide.
+IFB allows for sharing.
+
+2) Allows for queueing incoming traffic for shaping instead of
+dropping. I am not aware of any study that shows policing is
+worse than shaping in achieving the end goal of rate control.
+I would be interested if anyone is experimenting.
+
+3) Very interesting use: if you are serving p2p you may want to give
+preference to your own locally originated traffic (when responses come back)
+vs someone using your system to do bittorent. So QoSing based on state
+comes in as the solution. What people did to achieve this was stick
+the IMQ somewhere prelocal hook.
+I think this is a pretty neat feature to have in Linux in general.
+(i.e not just for IMQ).
+But i won't go back to putting netfilter hooks in the device to satisfy
+this. I also don't think its worth it hacking ifb some more to be
+aware of say L3 info and play ip rule tricks to achieve this.
+--> Instead the plan is to have a conntrack related action. This action will
+selectively either query/create conntrack state on incoming packets.
+Packets could then be redirected to ifb based on what happens -> eg
+on incoming packets; if we find they are of known state we could send to
+a different queue than one which didn't have existing state. This
+all however is dependent on whatever rules the admin enters.
+
+At the moment this 3rd function does not exist yet. I have decided that
+instead of sitting on the patch for another year, to release it and then
+if there is pressure i will add this feature.
+
+An example, to provide functionality that most people use IMQ for below:
+
+--------
+export TC="/sbin/tc"
+
+$TC qdisc add dev ifb0 root handle 1: prio
+$TC qdisc add dev ifb0 parent 1:1 handle 10: sfq
+$TC qdisc add dev ifb0 parent 1:2 handle 20: tbf rate 20kbit buffer 1600 limit 3000
+$TC qdisc add dev ifb0 parent 1:3 handle 30: sfq
+$TC filter add dev ifb0 protocol ip pref 1 parent 1: handle 1 fw classid 1:1
+$TC filter add dev ifb0 protocol ip pref 2 parent 1: handle 2 fw classid 1:2
+
+ifconfig ifb0 up
+
+$TC qdisc add dev eth0 ingress
+
+# redirect all IP packets arriving in eth0 to ifb0
+# use mark 1 --> puts them onto class 1:1
+$TC filter add dev eth0 parent ffff: protocol ip prio 10 u32 \
+match u32 0 0 flowid 1:1 \
+action ipt -j MARK --set-mark 1 \
+action mirred egress redirect dev ifb0

+Very funky action. I do plan to add to a few more things to it
+This is the basic stuff. Idea borrowed from the way ethernet switches
+mirror and redirect packets. The main difference with say a vannila
+ethernet switch is that you can use u32 classifier to select a
+flow to be mirrored. High end switches typically can select based
+on more than just a port (eg a 5 tuple classifier). They may also be
+capable of redirecting.
+
+Usage:
+
+mirred <DIRECTION> <ACTION> [index INDEX] <dev DEVICENAME>
+where:
+DIRECTION := <ingress | egress>
+ACTION := <mirror | redirect>
+INDEX is the specific policy instance id
+DEVICENAME is the devicename
+
+Direction:
+- Ingress is not supported at the moment. It will be in the
+future as well as mirror/redirecting to a socket.
+
+Action:
+- Mirror takes a copy of the packet and sends it to specified
+dev ("port" in ethernet switch/bridging terminology)
+- redirect
+steals the packet and redirects to specified destination dev.
+
+What NOT to do if you don't want your machine to crash:
+------------------------------------------------------
+
+Do not create loops!
+Loops are not hard to create in the egress qdiscs.
+
+Here are simple rules to follow if you don't want to get
+hurt:
+A) Do not have the same packet go to same netdevice twice
+in a single graph of policies. Your machine will just hang!
+This is design intent _not a bug_ to teach you some lessons.
+
+In the future if there are easy ways to do this in the kernel
+without affecting other packets not interested in this feature
+I will add them. At the moment that is not clear.
+
+Some examples of bad things NOT to do:
+1) redirecting eth0 to eth0
+2) eth0->eth1-> eth0
+3) eth0->lo-> eth1-> eth0
+
+B) Do not redirect from one IFB device to another.
+Remember that IFB is a very specialized case of packet redirecting
+device. Instead of redirecting it puts packets at the exact spot
+on the stack it found them from.
+Redirecting from ifbX->ifbY will actually not crash your machine but your
+packets will all be dropped (this is much simpler to detect
+and resolve and is only affecting users of ifb as opposed to the
+whole stack).
+
+In the case of A) the problem has to do with a recursive contention
+for the devices queue lock and in the second case for the transmit lock.
+
+Some examples:
+-------------
+
+1) Mirror all packets arriving on eth0 to be sent out on eth1.
+You may have a sniffer or some accounting box hooked up on eth1.
+
+---
+tc qdisc add dev eth0 ingress
+tc filter add dev eth0 parent ffff: protocol ip prio 10 u32 \
+match u32 0 0 flowid 1:2 action mirred egress mirror dev eth1
+---
+
+If you replace "mirror" with "redirect" then not a copy but rather
+the original packet is sent to eth1.
+
+2) Host A is hooked up to us on eth0
+
+# redirect all packets arriving on ingress of lo to eth0
+---
+tc qdisc add dev lo ingress
+tc filter add dev lo parent ffff: protocol ip prio 10 u32 \
+match u32 0 0 flowid 1:2 action mirred egress redirect dev eth0
+---
+
+On host A start a tcpdump on interface connecting to us.
+
+on our host ping -c 2 127.0.0.1
+
+Ping would fail since all packets are heading out eth0
+tcpudmp on host A would show them
+
+if you substitute the redirect with mirror above as in:
+tc filter add dev lo parent ffff: protocol ip prio 10 u32 \
+match u32 0 0 flowid 1:2 action mirred egress mirror dev eth0
+
+Then you should see the packets on both host A and the local
+stack (i.e ping would work).
+
+3) Even more funky example:
+
+#
+#allow 1 out 10 packets on ingress of lo to randomly make it to the
+# host A (Randomness uses the netrand generator)
+#
+---
+tc filter add dev lo parent ffff: protocol ip prio 10 u32 \
+match u32 0 0 flowid 1:2 \
+action drop random determ ok 10\
+action mirred egress mirror dev eth0
+---
+
+4)
+# for packets from 10.0.0.9 going out on eth0 (could be local
+# IP or something # we are forwarding) -
+# if exceeding a 100Kbps rate, then redirect to eth1
+#
+
+---
+tc qdisc add dev eth0 handle 1:0 root prio
+tc filter add dev eth0 parent 1:0 protocol ip prio 6 u32 \
+match ip src 10.0.0.9/32 flowid 1:16 \
+action police rate 100kbit burst 90k ok \
+action mirred egress mirror dev eth1
+---
+
+A more interesting example is when you mirror flows to a dummy device
+so you could tcpdump them (dummy by defaults drops all packets it sees).
+This is a very useful debug feature.
+
+Lets say you are policing packets from alias 192.168.200.200/32
+you don't want those to exceed 100kbps going out.
+
+---
+tc qdisc add dev eth0 handle 1:0 root prio
+tc filter add dev eth0 parent 1: protocol ip prio 10 u32 \
+match ip src 192.168.200.200/32 flowid 1:2 \
+action police rate 100kbit burst 90k drop
+---
+
+If you run tcpdump on eth0 you will see all packets going out
+with src 192.168.200.200/32 dropped or not (since tcpdump shows
+all packets being egressed).
+Extend the rule a little to see only the packets making it out.
+
+---
+tc qdisc add dev eth0 handle 1:0 root prio
+tc filter add dev eth0 parent 1: protocol ip prio 10 u32 \
+match ip src 192.168.200.200/32 flowid 1:2 \
+action police rate 10kbit burst 90k drop \
+action mirred egress mirror dev dummy0
+---
+
+Now fire tcpdump on dummy0 to see only those packets ..
+tcpdump -n -i dummy0 -x -e -t
+
+Essentially a good debugging/logging interface (sort of like
+BSDs speacialized log device does without needing one).
+
+If you replace mirror with redirect, those packets will be
+blackholed and will never make it out.
+
+cheers,
