Existing Functionality Broken Bugs
- https://bugs.launchpad.net/neutron/+bug/1590041 (SHOULD-FIX) - Regression, snat_namespace object creation ahead of time does not solve some external_gateway_update condition.
- https://bugs.launchpad.net/neutron/+bug/1583266 (SHOULD FIX) - watch_log_file=True causes fip to slow down. Symptom seen more with DVR routers.
- https://bugs.launchpad.net/neutron/+bug/1585165 (SHOULD FIX) - Floating ip not reachable after VM live migration (Seen in Liberty with DVR) - Seems to me like a duplicate but should triage it more on the symptoms.
- https://bugs.launchpad.net/neutron/+bug/1571676 (MUST FIX) - Static routes not added to FloatingIP Namespace.
- This approach can't really work because adding a static route in the FIP namespace for one tenant could impact traffic for another tenant.

- https://bugs.launchpad.net/neutron/+bug/1564757 - (MUST FIX) (FloatingIPError while agent restarts)

- https://bugs.launchpad.net/neutron/+bug/1456073 (High) - Block Migration with FIP breaks with DVR (MUST FIX)
- https://review.openstack.org/275073 (Nova side change) - Needs review
- https://review.openstack.org/#/c/286855/ (Tempest change) - Needs work - must merge before Nova patch
- https://review.openstack.org/275420 (Merged) - Neutron Server side DVR change
- https://review.openstack.org/#/c/260738/ (Merged) - L3 Agent side patch
- https://bugs.launchpad.net/neutron/+bug/1414559 (OVS drops RARP packets)
- https://bugs.launchpad.net/neutron/+bug/1557290 - (MUST FIX) DVR FIP agent gateway does not pass traffic directed at fixed IP
- https://bugs.launchpad.net/neutron/+bug/1447227 (Low) - Connecting two or more distributed routers to a subnet. (No one is working on it) (GOOD TO HAVE)

Gate failures (haleyb)
- Current failure rate: https://goo.gl/L1WODG
- Functional test failures seen in the Check queue, root cause yet to be identified.
- Single node check job failure rates are more when compared to neutron full job.
- VM failing to get DHCP address typical problem
- Bugs in Nova:
- Old bug to help in debugging the gate
- https://bugs.launchpad.net/neutron/+bug/1515360 - Tempest "SSHTimeout" failures (only for debugging)
Stable backports (haleyb)
Ihar created a page tracking all the potential backports from Mitaka to the stable releases. I have been going through it with the help of Swami to get stable/liberty, well, more stable. Bugs are removed from list as they merge.
We need to continue to be aggressive at proactively backporting fixes to the stable branches
This is a list of bugs with a fix that has been committed to the master branch, and are tagged with 'neutron-proactive-backport-potential+l3-dvr-backlog' (the wiki thinks the link is spam so I had to put a space in it)
- https://goo. gl/sx0KL5
Need to escalate the nova patch for the live migration. Since we have the tempest test running right now, we need someone from the nova team to take a look at the nova live migration patch.
#action haleyb will get something specific done this week
