There is no much participants today. 17:24:25 <imaximets> But it's time for the OVN meeting, so let's start. 17:24:35 <panda> I count more as a lurker than a participant 17:25:03 <dceara> Hi! Me too, nothing much I have to share this week 17:25:40 <_lore_> hi all 17:25:45 <_lore_> me too as well 17:27:03 <imaximets> Who wants to go first anyway? 17:27:57 <imaximets> zhouhan_, are you here today? 17:28:17 <imaximets> :) 17:28:27 <panda> I have a one liner. I'm looking at something to review in the ML, and I think I completed my onboarding. I can work on OVN only one day per week right now, but tomorro I'll try to move forward the patch on router-preference on non-periodic RA. 17:28:46 <numans> Hello everyone. 17:28:59 <numans> (Joining late) 17:28:59 <panda> I think I'll post the onboarding experience somewhere. Whoops two lines. 17:29:08 <numans> panda, hope my reply made sense ? 17:29:19 <numans> panda, and welcome to OVN :) 17:29:33 <zhouhan> imaximets: sorry, in parallel meeting. just one moment 17:29:34 <panda> numans: yes, it did, but I still have other question, I'll look more again tomorrow 17:29:41 <numans> ack. 17:29:49 <imaximets> zhouhan, sure. np. 17:30:23 <imaximets> panda, thanks for update. 17:30:33 <imaximets> who wants to go next? 17:30:59 <zhouhan> I can go quickly 17:30:59 <numans> I can go real quick. 17:31:03 <numans> zhouhan, go ahead 17:31:04 <numans> :) 17:31:08 <zhouhan> numans: thx 17:31:33 <zhouhan> I was mainly on code reviews, and I think I finished reviewing the I-P v5 17:32:00 <zhouhan> I am also working on the flow explosion solution 17:32:37 <zhouhan> There is another problem regarding flow explosion brought up by Girish, and I proposed a solution, but no time to work on that yet. 17:33:30 <zhouhan> imaximets: did you get some time to review the dp_hash patch? 17:33:55 <numans> zhouhan, you mean v9 ? 17:34:15 <numans> because tht was the last version posted. 17:34:16 <zhouhan> numans: Ah, sorry, typo. Yes, v9 17:34:33 <numans> no worries. Just checking in case you were reviewing old one. 17:34:51 <zhouhan> v9 was in my brain but I typed just v5, I don't know why :D 17:34:55 <imaximets> zhouhan, I only had a quick glance. I'm a bit concerned about passing hash computed in userspace to kernel. blp said same couple of weeks ago. I'll reply to the patch by the end of this week. 17:37:25 <zhouhan> imaximets: thx for the review. Yes there were 2 options discussed. I explained in the email why I choose this option in the end. 17:38:07 <zhouhan> imaximets: I will wait for your reply :) 17:38:19 <imaximets> zhouhan, ack. :) 17:38:27 <zhouhan> That's my update. numans please go ahead 17:38:42 <numans> Thanks. 17:39:23 <numans> I've been working on the v10 of I-P. It's almost ready. But before posting the series, I'll be doing some scale testing internally to be sure that there are no regressions. 17:39:33 <numans> So please expect some delay. 17:39:49 <numans> zhouhan and dceara , Thanks a ton for the reviews so far 17:40:04 <zhouhan> numans: np 17:40:14 <numans> I also posted another patch for ovsdb IDL. 17:40:27 <dceara> numans, np 17:40:39 <numans> thanks for the review zhouhan. I'll submit v2 soon addressing your comment. 17:40:46 <numans> That's it from me. 17:40:57 <zhouhan> v10? :) 17:41:26 <zhouhan> oh, I see, you mean the IDL v2 17:42:34 <numans> zhouhan, Yes. the IDL v2. 17:42:41 <zhouhan> p.s. the new flow explosion problem brought up by Girish is: #link https://mail.openvswitch.org/pipermail/ovs-discuss/2020-June/050187.html 17:43:15 <imaximets> I have a quick question. 17:43:26 <imaximets> I'd like to ask about backporting of the patch "raft: Avoid sending equal snapshots.". What everyone thinks about it. It might be good to have it at least in 2.13. 17:43:45 <numans> zhouhan, I saw that email. Is it a regression ? Any idea ? 17:44:14 <numans> imaximets, I'm fine. But probably zhouhan can answer better. 17:45:32 <imaximets> It's always unclear what is something a bug fix or an enhancement while talking about scale issues. 17:45:47 <imaximets> zhouhan, what do you think? 17:45:52 <zhouhan> numans: it's not a regression. It is from day one that the rules were added per router port, which is unnecessary 17:46:52 <zhouhan> imaximets: I think it is better to be backported if it is a big impact on scale 17:46:57 <numans> zhouhan, Ok. thanks. I was worried if I'm the culprit. Because I had a patch to address one issue. 17:47:19 <imaximets> zhouhan, ok. thanks. 17:47:41 <panda> numans: quick noob question. Are the scale tests in the repo ? 17:48:06 <imaximets> In this case I'm going to backport this patch to 2.13. 17:48:21 <numans> panda, yes. https://github.com/ovn-org/ovn-scale-test 17:48:31 <panda> numans: ah in the other :) thanks. 17:48:51 <imaximets> that's it from me. 17:49:05 <numans> panda, there's another repo which internally uses ovn-scale-test. That's still not in official ovn-org repo. For now its here - https://github.com/dceara/ovn-heater 17:49:12 <dceara> panda, there's also https://github.com/dceara/ovn-heater which runs ovn-scale-test on an ovn-fake-multinode virtual cluster 17:49:25 <dceara> panda, numans beat me to it :) 17:49:33 <panda> wow :) ok. 17:50:40 <imaximets> OK. Who wants to go next? 17:52:23 <imaximets> Last call for updates. :) 17:52:55 <numans> Looks like we are done. 17:53:07 <imaximets> ok. Let's call it a meeting. 17:53:15 <imaximets> Thanks, everyone. 17:53:31 <panda> bye 17:53:34 <imaximets> #endmeeting
