Oh, the above killer.c code misses the IFF_NO_PI flag, but it happens to
make no difference in this case.

Hi,
Yesterday an upstream switch reboot segfaulted all our ovs-vswitchd
instances at the same time. There's no MPLS or flow config in our OVS
setups, they run a bridge over a bond and several 802.1q interfaces. I
mention it here, though, as the backtrace starts similarly, so maybe
this is a more
I can confirm this bug.
ovs-vswitchd crashes when push_mpls flow action is required and output port is
