Re: HFSC warning issue

Re: HFSC warning issue

[Michal Pokrywka]

Through serveral days my friend has done some tests with kernels 2.6.39.x

2.6.39.1, 2.6.39.2 and 2.6.39.3 are still affected.

2.6.39 (debian version 2.6.39-1 from http://snapshot.debian.org/binary/?cat=l)
works for several hours without triggering the bug. If it persist for some hours
more we will bisect 2.6.39 and 2.6.39.1 and try to find the related patch.

HFSC warning issue

[François Delawarde]

Hi all,

I'm having the same HFSC issues as described here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=631945

Some user reports that he made it work by reverting this patch:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blobdiff;f=net/sched/sch_hfsc.c;h=47496098d35c2876cd0b5a88e1365922cc369ce9;hp=abd904be428717462395d62adb682023e64e17a5;hb=3b2eb6131e2f6ff646abb0fc69648179b8b70216;hpb=9c01ae58d4fee39e2af5b1379ee5431dd585cf62


Is this the correct solution? Any "clean" patch I could test that would
resolve this issue?

Thanks,
François.

Hmmm,

This commit in mention is the patch I submitted 
a while ago, namely:

http://kerneltrap.org/mailarchive/linux-netdev/2010/8/30/6284141

Whole rationale and short discussion regarding the 
change is in that thread. 

In a nutshell - it fixed certain scenario which could cause 
bursty traffic, but the change is just a minor adjustment. Let 
me sit a bit on this thing, and why it manages to trigger that 
warning ...

For a quick fix - reverting that commit should be perfectly 
safe - there were no other patches related to this one.

Missed explanation behind the change:

Not sure if its relevant but it seems that the ones that reported the
issue either use IFB or IMQ devices.

In my case, I use IMQ.
