The current packet injection loses ct_state in the process. When
the ct_state is lost we might commit to DNAT zone and perform
zero SNAT after the packet injection. This causes the first session
to be wrong as the reply packets are not unDNATted.
Instead of re-injecting the packet back into the pipeline when
we get the MAC binding, use paused controller action. The paused
controller action stores ct_state, which is important for the behavior
of the resumed packet.
At the same time bump the OvS submodule latest branch-3.3. This is
mainly for [0], which fixes metering for paused controller actions.
In order to make sure that the paused action works during upgrade add
the output implicitly. Once the upgrade is done northd will create option
to inform controllers that the implicit action is no longer needed.
[0] c560f6ca3257 ("ofproto-dpif-xlate: Fix continuations with associated
metering.")
Reported-at: https://issues.redhat.com/browse/FDP-439
Signed-off-by: Ales Musil <amu...@redhat.com>
---
v4: Add flag to ensure that the paused action works during upgrade.
v3: Rebase on top of main.
v2: Fix the Jira link and add ack from Mark.
