[Test Plan] 1. Execute the gate tests for the neutron-api-plugin-ovn charm, which performs a full cloud deployment and confirms two instances can spawn, get metadata and communicate with each other. 2. Enable IGMP snooping and have instances join a multicast group and validate that packets forward and check for RBAC errors. [Regression Potential] This is a very small patch that adds a static RBAC rule that ovn-northd writes into the database. The patch has already been available in the upstream branches since February 2021, we have also landed several similar patches upstream which have previously been made available to Focal through point release updates. [Original Bug Description] Hi, I've tested this on both 20.03 and 20.06. Looking into ovn-architecture.xml: https://github.com/ovn-org/ovn/blob/master/ovn-architecture.7.xml#L2530 It states that once RBAC is enabled, ovn-controllers will have access to some of the tables and that is hardcoded within OVN. That means once RBAC is enabled, IGMP_Group table is out of reach for ovn-controllers and will cause the following issue: 2021-02-06T17:17:40.916Z|00028|ovsdb_idl|WARN|transaction error: {"details":"RBAC rules for client "REDACTED" role "ovn-controller" prohibit row insertion into table "IGMP_Group".","error":"permission error"} Reported on upstream repo: https://github.com/ovn-org/ovn/issues/77 Proposed patch: https://github.com/phvalguima/ovn/commit/3419d9946c51b413f816ceb82372677e4afdbe9d To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1914988/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-translations-coordinators Post to : ubuntu-translations-coordinators@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-translations-coordinators More help : https://help.launchpad.net/ListHelp
