Mon Apr 10 15:27:59 UTC 2023

Hello Jakub, or anyone else affected,

Accepted neutron into ussuri-proposed. The package will build now and be
available in the Ubuntu Cloud Archive in a few hours, and then in the
-proposed repository.

Please help us by testing this new package. To enable the -proposed
repository:

  sudo add-apt-repository cloud-archive:ussuri-proposed
  sudo apt-get update

Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-ussuri-needed to verification-ussuri-done. If it does
not fix the bug for you, please add a comment stating that, and change
the tag to verification-ussuri-failed. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at

Bug description:
  [Impact]
  Backport fix to Focal/Ussuri so that neutron-ovn-db-sync-util does not trip up when it finds ovn ACL table entries with a "label" column that does not exist in neutron db.

  [Test Plan]
   * Deploy Openstack Ussuri
   * Upgrade OVN to 22.03 (https://charmhub.io/ovn-chassis/configure?channel=22.03/stable#ovn-source)
   * Create a network with security groups
   * Create an instance using this network so that ports get tied to SGs
   * Go to neutron-api unit (neutron-server) and do the following
   * cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.no_keystone_authtoken
   * remove "auth_section = keystone_authtoken" in the [nova] section of neutron.conf.no_keystone_authtoken
   * run 'neutron-ovn-db-sync-util --config-file /etc/neutron/neutron.conf.no_keystone_authtoken --config-file /etc/neutron/plugins/ml2/ml2_conf.ini --ovn-neutron_sync_mode repair'
   * the above should not produce any errors like the following:

      RuntimeError: ACL ... already exists

  [Regression Potential]
  there is no regression potential expected with this patch.

  --------------------------------------------------------------------------

  OVN introduced a new column in ACL table. The column name is label and
  when running db-sync script, we compare ACL generated by the ovn mech
  driver from Neutron DB with the actual ACLs in the OVN DB. Because of
  the new label column, everything seems like a new ACL because the
  column differs to what Neutron generated. Thus the script attempts to
  create a new ACL that already exists.
