Bug description:
[Impact]
Users of Open vSwitch on Focal will not be able to upgrade to v2.16.0 or
newer until this long standing kernel bug has been fixed.
Users of Open vSwitch on Jammy will be affected by this bug and
have no user space fix available. This bug currently blocks the
OpenStack Engineering team's charm product gate.
[Test Plan]
Execute the OVN system testsuite utilizing the kernel data path with the test
synthesis patch in comment #7 applied.
In addition to that validating that the OpenStack charm test gate is
unblocked would be valuable.
[Regression Potential]
The regression potential can be considered as low because:
- The calls added in the openvswitch kernel datapath code would
prior to Open vSwitch 2.16.0 have been initiated from the
userspace code and by chance concealed this bug.
- After an optimization done in 2.16.0 the kernel bug was
revealed and these calls now must be made from the kernel
datapath to retain functionality in use in the wild.
[Original Bug Description]
If you have two hvs where hv1 is the gateway chassis and you have an instance
running on hv2.
On instance on hv2 hairpin traffic works for the first session, but
not for the next:

We made an attempt at using OVN built with [0], but that did
unfortunately not help.
If we however revert [1] it works again:
