Subject: openvswitch: Respect conntrack zone even if invalid
From: Joe Stringer <joe@xxxxxxx>
[ Upstream commit d110986c5ddb1caf576e8576044c0c831e3e7fa4 ]
If userspace executes ct(zone=1), and the connection tracker determines
that the packet is invalid, then the ct_zone flow key field is populated
with the default zone rather than the zone that was specified. Even
though connection tracking failed, this field should be updated with the
value that the action specified. Fix the issue.
