Package: linux-image-2.6.32-5-xen-amd64
Version: 2.6.32-35
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
On debian 6.0.2 i am running a XEN guest with 2.6.32-5-xen-amd64
from linux-image-2.6.32-5-xen-amd64 (version 2.6.32-35).
The bug sounds like it comes from the openvirtuozzo patch.
When attempting to do:
# sh -x ./foo add 5038
+ what=add
+ port=5038
+ bitspersec=30000
+ bps=3750bps
+ burst=3kb
+ tc qdisc add dev eth0 root handle 1:0 htb
+ tc class add dev eth0 parent 1:0 classid 1:666 htb rate 100mbit ceil 100mbit
+ tc qdisc add dev eth0 parent 1:666 handle 2:0 sfq perturb 10
+ tc filter add dev eth0 parent 2:0 protocol ip u32 match ip sport 5038 0xff00
police rate 3750bps burst 3kb mpu 0 action drop/continue flowid 2:0
Killed
+ [ add = add ]
+ tc qdisc show dev eth0
[hangs forever]
dmesg tells me:

Hi,
your bug has been filed against the "linux-2.6" source package and was filed for
a kernel older than the recently released Debian 7.0 / Wheezy with a severity
less than important.
We don't have the ressources to reproduce the complete backlog of all older
kernel
bugs, so we're closing this bug for now. If you can reproduce the bug with
Debian Wheezy
or a more recent kernel from testing or unstable, please reopen the bug by
sending
a mail to [email protected] with the following three commands included in
the
mail:
reopen BUGNUMBER
reassign BUGNUMBER src:linux
thanks
Cheers,
Moritz
