Build Update for ovsrobot/ovn
Duration: 21 mins and 53 secs
Commit: 0883707 (series_192940)
Author: Mark Michelson
Message: Add ECMP symmetric replies.
When traffic arrives over an ECMP route, there is no guarantee that the
reply traffic will egress over the same route. Sometimes, the nature of
the traffic (or the intervening equipment) means that it is important
for reply traffic to go out the same route it came in.
This commit introduces optional ECMP symmetric reply behavior. If
configured, then traffic to or from the ECMP route will be sent to
conntrack. New incoming traffic over the route will have the source MAC
address and incoming port saved in the ct_label. Reply traffic then uses
this saved information to send the packet back out the same way it came
To facilitate this, a new table was added to the ingress logical router
pipeline. The ECMP_STATEFUL table is responsible for committing to
conntrack and setting the ct_label when it detects new incoming traffic
from the route.
Since ingress pipeline logic on the logical router depends on ct state
of a particular hypervisor, this feature is only usable on gateway
