commit 451c21571f40ca83eb3189e5c924b03c0561f853 Author: Lucian Petrut <[email protected]> Date: Thu Sep 12 17:34:04 2019 +0300 ovsdb monitor: handle modified ports This patch ensures that the ovsdb monitor propagates the events received for modified ports. We'll use a new list for the modified ports, which the neutron ovs agent can handle. In particular, this will cover the situation in which the ofport changes. When using recent OVS Windows versions, VM ofports change to -1 (invalid) when the VMs are shut down, receiving a valid ofport when the VMs are powered back on (different than the initial one). With this patch applied, "modify" events will be propagated to the ovs agent, which will then update the OpenFlow rules. The old rules are cleaned up by "update_stale_ofport_rules" once the invalid ofport is detected.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1843870 Title: ovsdb monitor ignores modified ports Status in neutron: Fix Released Bug description: The ovsdb monitor used by Neutron ignores modified ports. For this reason, some port changes will not be handled. One particular case comes from ofport changes. On Windows, depending on the OVS version, the ofport can change after VM reboots. The neutron ovs agent will have to update the flows in this situation, which it does, but only when "minimize_polling" is disabled. The neutron ovsdb monitor should propagate the events received for modified ports. Those can either be part of the "added" device list or have a separate one for modified ports.
