Subject: OOPS: 2.6.8.1 QoS and routing conflict (bug)
Date: Mon, 16 Aug 2004 03:35:30 -0300 (BRT) [thread overview]
Message-ID: <XFMail.20040816033530.fraga@abusar.org> (raw)
Hi! First of all the most important:
a) the following "oops" was introduced in the 2.6.8 kernel (2.6.7 and
below are not affected)
b) this is a *reproducible* bug
***
[1.] One line summary of the problem:
Oops when trying to set default route when QoS is configured
and active
[2.] Full description of the problem/report:
When I upgraded from 2.6.7 to 2.6.8(.1) kernel, it showed an
Oops (below with ksymoops output) when the initialization scripts tried to
set the default route with the following command:
ip route add default via <ip>
I use wondershaper (lartc.org) script to control my network traffic.
The oops just happens when I use wondershaper script, in other words,
just when HTB is properly configured:

Otherwise (if htb is compiled but *not* configured), default route can
be set without problems. So I think the problem is related with the changes
kernel 2.6.8 had in the QoS section.

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
ip utility, iproute2-ss020116
[X.] Other notes, patches, fixes, workarounds:
The only workaround was to not use QoS at all.
Since the bug does not exist in the 2.6.7 kernel, I think
it will be easy to figure it out what's the problem with the
changes made in the 2.6.8 kernel regarding QoS section or even
networking.

Thank you very much.
Ps: I'll do everything I can to help solve this oops.
