Hi Ben,
2016-11-30, Ben Pfaff:
Do you have any idea what in your OpenFlow pipeline might do that,
i.e. is there anything especially tricky in the OpenFlow flows?

The setup involves three OVS bridges connected with patch-ports: br-int
-- br-tun -- br-mpls, with the traffic that triggers the assert being
processed by br-int with a NORMAL action (ie. MAC learning).
The flows in this setup aren't particularly tricky, I think, although
I'm not sure what qualifies as tricky or non-tricky :)
Anyway, since yesterday I managed to identify the event that trigger the
assert, by adding more logging before the assert and displaying the
actions taken:

base_flow->nw_frag failed in commit_set_ipv4_action()
Noticing that the actions include two outputs (to ports 9 and 1, which
mapped respectively to an eth interface and to br-int linux kernel
network interface), I thought that the issue could be related to an
absence of MAC learning entry in br-int. I was then able to reliably
trigger the assert/crash/restart, without waiting for an unknown time,
by artificially expiring all MACs (ovs-appctl fdb/flush).
The file attached contains detailed information on the flow tables of
the three bridges, dpctl of active flows, and ofproto/trace of a flow
that on a MAC entry expiration, would trigger the assert.
I hope this information can help identify what ultimately ends up
triggering this assert.
As a side comment: I understand that this assert acts as a safeguard for
something that should never happen, but at the same time it would seem
nice to have OVS fail in a more smoother way than a crash/restart.
Best,
-Thomas
