some tc commands fail on 2.6.29-rc6-git5, works on 2.6.28.7

[Joao Correia]

Hello all

On a Fedora 9 box, with a 2.6.29-rc6-git5 compiled with the same
.config as the previously running 2.6.28.7, i get:

[root@duron ~]# /sbin/tc qdisc add dev eth2 handle ffff: ingress
[root@duron ~]# /sbin/tc filter add dev eth2 parent ffff: protocol ip
prio 50 u32 match ip src 0.0.0.0/0 police rate 30320kbit burst 500k
drop flowid :1
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
[root@duron ~]# uname -a
Linux duron 2.6.29-rc6-git5 #3 SMP Sun Mar 1 00:02:56 WET 2009 i686
athlon i386 GNU/Linux
[root@duron ~]#

There is no information regarding this event on dmesg or /var/log/messages.
eth2 exists and is working properly, under 2.6.28.7 it works (without
complaints).

Please advise on what steps I may take to provide more information. I have
both kernel sources and availability to apply patches/recompile as needed.

Thank you very much for your time,

Hi,

I've just repeated your commands (with eth0) on the current Linus' tree
and it works OK. Check your .config and "modules_install" again, and if
no result send gzipped .config and show "lsmod" and "tc -V" output after
these commands above.

Cheers,
Jarek P.

Hello again

Sorry for taking so long, been busy with some unexpected work.

I have checked the .config and can not (to the extent of my not-guru
knowledge) find anything out of place. Excuse me if its obvious and it
didnt strike me yet.

The commands asked plus some others i remembered give the output at the bottom.
Where can i send the gzipped .config? Not the list, I imagine?

I have confirmed again that the exact same commands (as on the
original message), work flawlessly on 2.6.28.7 without a hitch, and,
AFAIK, work as intended. I have also tried the latest 2.6.29-rc6-git7
and it still fails like on git6.

It happens even with other NIC's (both a D-Link gigabit and an onboard
Atheros A1L gigabit (output of lspci -vv at the end of this message).

Thank you very much for your time,
Joao Correia

Joao, you don't need to be sorry at all - on the contrary I'm
extremely sorry! I was so focused on the kernel version but ignored
updating iproute, and it looks like this matters here.

So you're right. Alas I'll not be able to look at it until "tomorrow"
in the evening.

Thanks for the report,
Jarek P.

I have also reproduced this on Linus' latest 2.6.29-rc6 tree, using tc
version iproute2-ss071016 and a kernel config with all traffic control
features enabled.

The error reported by tc comes from the kernel-level check added by:

	commit c1b56878fb68e9c14070939ea4537ad4db79ffae
	Author: Stephen Hemminger <shemminger@vyatta.com>
	Date:   Tue Nov 25 21:14:06 2008 -0800

    	tc: policing requires a rate estimator

    Found that while trying average rate policing, it was possible to
    request average rate policing without a rate estimator. This results
    in no policing which is harmless but incorrect.

    Since policing could be setup in two steps, need to check
    in the kernel.

I got the same error when using the tc version iproute2-ss090115 built
this evening from the public git repository.

Hello

Just to confirm that i also have all traffic control/shaping (QoS,
connection limits, scheduling, etc) enabled on the config i use.

Its not just the specific version of tc i posted, i tried one from
last year (october, but i didnt note the exact build) with the same
result.

Maybe good idea to use strace? (i dont know which flags useful, but usually i 
use "-s 65536")
Just maybe it will give a bit more ideas what is happening.
But sure netdev developers can tell, if it is useful or not.

Very nice diagnose, thanks!

PS: after upgrading iproute I couldn't reproduce this seemingly OK
test with older versions anymore...

------------------->
pkt_sched: act_police: Fix a rate estimator test.

A commit c1b56878fb68e9c14070939ea4537ad4db79ffae "tc: policing requires
a rate estimator" introduced a test which invalidates previously working
configs, based on examples from iproute2: doc/actions/actions-general.
This is too rigorous: a rate estimator is needed only when police's
"avrate" option is used.

Hello

Confirmed working now on latest 2.6.29-rc6 git.

Thank you very much all for the prompt answer and solution, really impressive.

Back to work on the ultimate custom firewall *evil laugh*.
