| |
While looking at the "Soft-Lockup/Race in networking in 2.6.31-rc1+195 ( possibly caused by netem)" issue (http://lkml.org/lkml/2009/7/2/519) I noticed some serious problems in the hrtimer related code of net/sched/sched/sch_cbq.c.
The following patch series addresses these.
I'm not entirely sure whether patch [1/3] covers all possible concurrent modifications, but it fixes the most obvious ones. The remaining details are left to the networking experts.
Patches [1/3] and [2/3] might be stable material as well.
Thanks,
tglx
