[Bug 1210373] [NEW] kernel crash at veth interface shutdown (net_carrier_off)


You have been subscribed to a public bug:

When destroying a veth interface when both members of the veth pair are
up, a kernel bug is triggered.

How to reproduce:

ip link add type veth
ip link set veth0 up
ip link set veth1 up
ip link del veth0

I've uploaded the kernel log to

In some cases, it completely locks up the machine. For instance, when a
LXC ocntainer is stopped, the bug happens, but the machine is then
frozen (no console, no reply to ping). I've uploaded the corresponding
kernel log to https://gist.github.com/jpetazzo/6190908.
