Bug 86729 – Bug in iproute2 (2.6.11.20050310) breaks dsmark qdiscs

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description dswhite42 2005-03-25 19:09:50 UTC]

A bug has been found in iproute2-2.6.11-0503xx that breaks the creation of dsmark qdiscs.  Below is a fairly simply tc command, but tc chokes on it (even though dsmark capabilities are built into both iproute2 and my gentoo kernel 2.6.11):

> tc qdisc add dev eth0 handle 1:0 root dsmark indices 8 default_index 0
RTNETLINK answers: Invalid argument

The bug report from the LARTC mailing list is here: http://mailman.ds9a.nl/pipermail/lartc/2005q1/015295.html
and the developer patch is here: 
http://mailman.ds9a.nl/pipermail/lartc/2005q1/015298.html

I will attach the patch, which I've applied to my portage overlay directory for iproute2.  It seems to have solved the problem.

In case you need it, my "emerge info" is below.  Thanks!
