Title:
[Ussuri] Neutron API writes to the Southbound DB, does not play well
with OVN RBAC
Status in charm-neutron-api-plugin-ovn:
Fix Released
Status in charm-ovn-central:
Fix Released
Status in neutron:
Confirmed
Bug description:
At Ussuri Neutron API has begun doing writes directly to the
Southbound DB, there does not appear to be a accompanying RBAC role
for this, so do we need to give it access to the private port
currently reserved for ovn-northd?
The offending change in upstream Neutron arrived here:
https://github.com/openstack/networking-
ovn/commit/70c3d06656e15e11a0daf9c3732a21c8ce601c4d
