[SRU][J][PATCH 0/1] net: openvswitch: fix misuse of the cached connection on tuple changes

[Frode Nordahl]

Buglink: https://launchpad.net/bugs/1967856

SRU Justification:

[Impact]

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.

[Fix]

* cba7c76ea1e15fddb95706eb64659644a6a02b38 "net: openvswitch: fix
misuse of the cached connection on tuple changes"

[Test Plan]

A reproducer has been attached to the bug and can be executed with
the OVS system testsuite.

[Where problems could occur]

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.
