To whom it may concern,
I recently attempted to use simple tc action pedit commands on the man
page and I ran into some errors. The following is some information
about my version of iproute and my machine:
----------------------------
the following is my iproute package information
Loaded plugins: fastestmirror, langpacks
iproute-3.10.0-74.el7.x86_64
changed_by = 0
checksum_data =
f18d9a19e6531081a605086e5003422a87846854a10a306d122b59ff7bebb9d7
checksum_type = sha256
command_line = update
from_repo = base
from_repo_revision = 1480942829
from_repo_timestamp = 1480942901
installed_by = 4294967295
origin_url =
http://mirror.confluxtech.com/centos/7/os/x86_64/Packages/iproute-3.10.0-74.el7.x86_64.rpm
reason = user
releasever = 7
var_uuid = df8acb3e-a9df-4ffe-b95f-0311b19b2d33
---------------------------------------------------------------------------------
I am running the latest version of Centos 7 with kernel version:
3.10.0-514.26.2.el7.x86_64
-------------
The following are the first three commands of the man page that I run
and their output
---------------------------------------------------------------------------------
tc qdisc replace dev eth0 root handle 1: htb
tc qdisc add dev eth0 ingress handle ffff:
tc filter add dev eth0 parent 1: u32 \
> match ip dport 23 0xffff \
> action pedit pedit munge ip dport set 22
bad pedit parsing
Illegal pedit construct (ip)
Usage: ... pedit munge <MUNGE>
Where: MUNGE := <RAW>|<LAYERED>
<RAW>:= <OFFSETC>[ATC]<CMD>
OFFSETC:= offset <offval> <u8|u16|u32>
ATC:= at <atval> offmask <maskval> shift <shiftval>
NOTE: offval is byte offset, must be multiple of 4
NOTE: maskval is a 32 bit hex number
NOTE: shiftval is a is a shift value
CMD:= clear | invert | set <setval>| retain
<LAYERED>:= ip <ipdata> | ip6 <ip6data>
| udp <udpdata> | tcp <tcpdata> | icmp <icmpdata>
For Example usage look at the examples directory
bad action parsing
parse_action: bad value (7:pedit)!
Illegal "action"
---------------------------------------------
The first two commands run without error. However the third command fails.
It apparently does not recognize the ip command. This seems strange to
me since the commands I run are on the tc-pedit man page. Any help on
this issue would be appreciated.
Sincerely,
Tyler Bautista

Can you reproduce the problem with vanilla iproute2? You are using RHEL7's iproute package, which has a number of known issues in pedit action: https://bugzilla.redhat.com/show_bug.cgi?id=1322406 These are planned to be resolved for RHEL7.5, not sure when it will land in CentOS.

I have gotten a solution working so feel free to ignore the rest of this email. By vanilla iproute2 do you mean the latest package through the yum or apt repository? All I can tell you is that in the example I gave the iproute2 package was the latest one through the RHEL 7 yum repository. Otherwise I will need clarification on what vanilla means. I attempted the above example code on two other Ubuntu machines, one of which I can confirm is Ubuntu 16.04 LTS. Unfortunately I am not at that machine right now so I cannot give you the output. Both machines gave similar error messages. The reason I emailed you via netdev was because the example code I used was taken verbatim from the tc-pedit man page on my machine. The man page also gave me email addresses to contact in case an error was found with the man page, which is what I did. I did get the code to work when using the latest version of iproute2, so I assume the only practical solution is to manually install the latest version of iproute2 or wait for the various distros of Linux to use updated iproute2. I appreciate your help. Have a nice day.

'Vanilla' is a widely used term[1], I meant using latest iproute2 from upstream[2], ideally from Git. You have to report problems with RHEL packages in Red Hat bugzilla[3].
