15:02:28 <mlavalle> #topic Announcements
15:02:56 <mlavalle> Some time today, we are going to cut our final rc (2) for the Rocky release
15:03:32 <mlavalle> as many of you know from the Neutron meeting, we wanted to include bug fixes that were merged since rc-1 two weeks ago
15:03:41 <mlavalle> I think we are in good shape
15:04:09 <Swami> mlavalle: there was one critical bug that was mentioned in DVR, not sure if we need to include that. It is a revert.
15:04:33 <mlavalle> Swami: do you have the url handy?

15:11:51 <Swami> ok, will start
15:12:05 <Swami> As I mentioned the first one shown above is the critical one.
15:12:31 <Swami> #link https://bugs.launchpad.net/neutron/+bug/1783654
15:12:31 <openstack> Launchpad bug 1783654 in neutron "DVR process flow not installed on physical bridge for shared tenant network" [Critical,In progress] - Assigned to Swaminathan Vasudevan (swaminathan-vasudevan)
15:12:53 <Swami> Since I pushed in the revert patch please review it.
15:13:05 <slaweq> hi
15:13:07 <slaweq> sorry for late
15:13:41 <Swami> The next one is
15:13:45 <Swami> #link https://bugs.launchpad.net/neutron/+bug/1786169
15:13:45 <openstack> Launchpad bug 1786169 in neutron "DVR: Missing fixed_ips info for IPv6 subnets" [Medium,In progress] - Assigned to Dongcan Ye (hellochosen)
15:14:10 <Swami> There is a patch under review #link https://review.openstack.org/590157
15:14:20 <Swami> If not reviewed please review it.
15:14:55 <Swami> The next one in the list is #link https://bugs.launchpad.net/neutron/+bug/1786272
15:14:55 <openstack> Launchpad bug 1786272 in neutron "Connection between two virtual routers does not work with DVR" [Medium,Triaged] - Assigned to Brian Haley (brian-haley)
15:15:05 <Swami> haleyb: I tried the reproduce this problem.
15:15:32 <slaweq> Swami: I reproduced it
15:15:57 <Swami> haleyb: It seems that is by design. The only way you can communicate between two routers is you need to have a third common subnet connecting the two routers. I have updated my information in the bug report.
15:16:19 <Swami> slaweq: Yes I was also able to see the problem.
15:16:49 <haleyb> Swami: i thought we did have a subnet between them
15:17:30 <slaweq> today I was trying it a bit today and when I removed from both nodes rule added by https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/openvswitch/agent/ovs_dvr_neutron_agent.py#L457
15:17:47 <slaweq> then it connection between such 2 vms was working
15:17:59 <Swami> haleyb: If we have a subnet between the routers, and add a static route to reach the other subnet it should work. Only in isolated cases it should not work. By looking at your bug report, it says that you are only adding two subnets.
15:18:00 <slaweq> but I have no idea about other consequences of that :)
15:18:33 <slaweq> in this bug there are 3 different networks used
15:19:03 <haleyb> Swami: the third subnet in the bug report was on the Wan network, which is where both routers are attached
15:19:10 <Swami> haleyb: Ok, in that case I will have to relook into this issue, may be I missed something.
15:19:36 <haleyb> i think if that was an external network it would work
15:19:56 <slaweq> haleyb: yes, then it would work
15:20:05 <slaweq> also in non-dvr scenario it works fine
15:20:13 <Swami> haleyb: Yes that would have worked.
15:20:33 <Swami> haleyb: Anyway I will recheck it.
15:21:10 <Swami> The next one in the list is
15:21:14 <Swami> #link https://bugs.launchpad.net/neutron/+bug/1785227
15:21:14 <openstack> Launchpad bug 1785227 in neutron "Router port: no dataplane update on change" [Medium,Confirmed]
15:21:49 <Swami> It seems that when router port update happens, there is no notification in a specific case.
15:22:51 <haleyb> right, i reproduced but hadn't tracked down source
15:22:52 <Swami> Not patch yet for review on this bug. I will  try to see if I can push one.
15:23:36 <Swami> haleyb: yes I saw your message on the bug.
15:23:43 <Swami> The next one is #link https://bugs.launchpad.net/neutron/+bug/1774459
15:23:43 <openstack> Launchpad bug 1774459 in neutron "Update permanent ARP entries for allowed_address_pair IPs in DVR Routers" [High,Confirmed]
15:24:22 <Swami> I have added some comments in the bug, I am not a openvswitch expert, but if anyone in this group is, could you please look into my suggestions for this bug.
15:25:06 <Swami> Was thinking if we can address this issue through openflow rules and ARP Responder, please let me know your thoughts.
15:26:10 <mlavalle> yeah, t\we've been dealing with this issue for some time. I'll take alook
15:26:12 <mlavalle> again
15:26:36 <Swami> mlavalle: thanks
15:27:13 <Swami> mlavalle: haleyb: slaweq: #link https://review.openstack.org/#/c/577012/ This patch is failing a unit test that passed in queens and master, not sure what is wrong with the pike setup.
15:27:34 <Swami> can one of you take a look, or else should we suppress this unit test for pike and push this patch.
15:28:07 <slaweq> Swami: which UT is failing there?
15:28:14 <slaweq> I see al UT jobs green
15:28:17 <slaweq> *all

15:29:18 * mlavalle looking
15:30:03 <slaweq> I saw such error somewhere already but I don't remember when and where :/
15:30:22 * haleyb doesn't remember either
15:30:29 <slaweq> I can take a look for this one but probably not this week
15:30:36 <Swami> slaweq: ok thanks, if you remember please let me know or comment in the patch.
15:30:44 <Swami> slaweq: not urgent
15:30:45 <slaweq> Swami: sure
15:30:52 <Swami> mlavalle: that's all I had. Back to you
15:31:38 <mlavalle> Swami: I am looking at another functional test failure in Queens (as I will mention in a minute). I'll get back to you if I see relationship
