Description Beju 2010-03-12 20:06:13 UTC
I can't assign traffic to queues using u32 match. With the script I've used:
--------
tc qdisc add dev eth0 root handle 1: htb default 12

tc class add dev eth0 parent 1: classid 1:1  htb rate 100kbps ceil 100kbps
tc class add dev eth0 parent 1:1 classid 1:10 htb rate 50kbps ceil 50kbps
tc class add dev eth0 parent 1:1 classid 1:12 htb rate 30kbps ceil 30kbps

tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 classid 1:10
match ip src 192.168.0.193/32

tc qdisc add dev eth0 parent 1:10 handle 20: pfifo limit 5
tc qdisc add dev eth0 parent 1:12 handle 40: sfq perturb 10
--------
All traffic is assigned to default 1:12 class, even from 192.168.0.193. 
The same happens when I use 'match ip src 192.168.0.0/22' (internal network address), 'match ip dport' or 'match u32 0xc0a800c1 0xffffffff at 12'. The only case I found it to work is when I specify mask of 0, i.e. 'match ip src 0/0'. 

The problem is present on two gentoo boxes with 2.6.30 and 31 kernels. Is anyone else experiencing it? Do I need some specific kernel configuration?

Reproducible: Always

Steps to Reproduce:
1. Execute the commands in bug description.


Actual Results:  
Trafic from 192.168.0.193 goes to class 1:12

Expected Results:  
Trafic from 192.168.0.193 goes to class 1:10

2.6.31 kernel config
Comment 2 SpanKY gentoo-dev 2010-03-14 15:46:10 UTC
iproute2-2.6.33 is in the tree ... i would try that and if it still fails, try e-mailing the list at netdev@vger.kernel.org.  i'm not sure how many people here are actually familiar with the lower net internals.
Comment 3 Beju 2010-03-14 18:33:36 UTC
Thanks, I'll try that tomorrow, although I have already tried with iproute-2.6.33 compiled manually from source - it doesn't work. The worst thing is that I don't know if it's a kernel problem, iproute2 problem or maybe I've messed up with my script, because I cannot imagine how would all these network routers work if such a major feature would be broken, and google says nothing about the problem.
Comment 4 SpanKY gentoo-dev 2010-11-21 21:45:59 UTC
i noticed that iproute2 has been mishandling iptables for a while ... could you try the new iproute2-2.6.35-r3 ebuild ?
