| mmichelson | #startmeeting ovn_community_development_discussion | 17:22 |
| openstack | Meeting started Thu Jul 23 17:22:49 2020 UTC and is due to finish in 60 minutes. The chair is mmichelson. Information about MeetBot at http://wiki.debian.org/MeetBot. | 17:22 |
| openstack | Useful Commands: #action #agreed #help #info #idea #link #topic #startvote. | 17:22 |
| openstack | The meeting name has been set to 'ovn_community_development_discussion' | 17:22 |
| mmichelson | Sorry for the late start. Things are suddenly a bit crazy today | 17:23 |
| mmichelson | ovnkube CI is having problems with OVN 20.06 | 17:23 |
| mmichelson | Still gathering facts on the matter. | 17:23 |
| mmichelson | But as for my activity the past week | 17:23 |
| mmichelson | I put up a patch for lb_force_snat_ip and dnat_force_snat_ip to work for dual stack | 17:24 |
| mmichelson | And I put up a patch for ECMP symmetric replies | 17:24 |
| mmichelson | That ECMP patch needs fixing because there are some test failures that numans pointed out | 17:24 |
| mmichelson | blp, I know you're mostly lurking, but something to bring to your attention is that OVN committers should probably be made maintainers in patchwork | 17:25 |
| mmichelson | blp, if you have the proper contact info for getting that done, then OVN maintainers can update patch states when desired. | 17:25 |
| blp | mmichelson: I don't think there is any self-service administration for patchwork, that is, I don't think that I can do that myself. | 17:26 |
| mmichelson | blp, ok, imaximets said that you might know who to get in contact with though | 17:26 |
| blp | mmichelson: In the past, I've always emailed one of the owners of the patchwork instance. My guess is that they'd take requests from others too, or I could send an email recommending that they take it from you. | 17:26 |
| mmichelson | blp, OK. I'm willing to send the message myself. But not sure who to send to. | 17:27 |
| mmichelson | (I'd CC the OVN committers) | 17:27 |
| blp | Jeremy Kerr <jk@ozlabs.org> is who I | 17:27 |
| blp | ve emailed in the past | 17:27 |
| mmichelson | blp, OK thanks. | 17:28 |
| mmichelson | And that's all I wanted to bring up. | 17:28 |
| blp | OK. Do you want to start by contacting Jeremy? I'll back you up as needed. Or we can do it another way if you prefer. | 17:28 |
| zhouhan | I can go next. | 17:30 |
| *** qweghj has joined #openvswitch | 17:30 | |
| zhouhan | I am catching up after the vacation. I just submitted the formal patch series for avoid ARP related flow explosion: #link https://patchwork.ozlabs.org/project/openvswitch/list/?series=191714 | 17:31 |
| zhouhan | As I saw the test report from Girish for the RFC was effective | 17:31 |
| zhouhan | I will catch up with some reviews, first one would be the ECMP patch from mmichelson | 17:32 |
| zhouhan | That's my update | 17:32 |
| flaviof | Nice. Avoiding flow explosion is always a good thing. Let me jump next... | 17:34 |
| flaviof | I have just one small announcement to make to folks who may know or use ovn-org/ovn-fake-multinode. | 17:34 |
| flaviof | Thanks to Eelco, we now have the ability to build ovs/kernel and run test traffic. If that is something that interests you, take a look at: | 17:34 |
| flaviof | #link https://github.com/ovn-org/ovn-fake-multinode/blob/master/README_DEVELOPMENT.md Using ovn-fake-multinode for development and testing | 17:34 |
| flaviof | Huge thanks to chaudron! | 17:35 |
| flaviof | That is it from me. | 17:35 |
| zhouhan | thanks flaviof. That's helpful, but I don't use vagrant. Does it make big difference? | 17:37 |
| *** qweghj has quit IRC | 17:37 | |
| flaviof | oh not at all. you can use the scripts on any env. Vagrant just help getting the host to run the cluster. | 17:38 |
| zhouhan | I have tried it before, which worked well. But I didn't try the "change and retest" process on that yet. Does it require rebuilding the docker images? | 17:39 |
| flaviof | nope, which is a huge time saver. once you have the images you can restart very easily/fast | 17:39 |
| zhouhan | flaviof: oh that's great! | 17:40 |
| panda | oneline from me, I'm a but swamped at the moment with the rest, so even my OVN day was put on hold, not sure If I can do something tomorrow, but I'll try. I have two bugs on my list and one has a poste solution but needs improvement. | 17:42 |
| panda | :( sorry | 17:42 |
| mmichelson | panda, we've all been there. | 17:43 |
| blp | panda: Have we met before? I know at least one Panda. | 17:44 |
| * numans_ joins now and says Hi to everyone | 17:44 | |
| panda | blp: there are not many pandas out there, but probably we haven't met. | 17:44 |
| *** numans_ is now known as numans | 17:45 | |
| panda | numans: you can say you're early for next meeting. | 17:45 |
| blp | I guess you are probably not Aurojit Panda formerly at Berkeley. | 17:45 |
| zhouhan | (most pandas in the world are in my hometown :) | 17:45 |
| blp | zhouhan: :-) | 17:45 |
| panda | blp: nope, sorry to crush your expectation. I'm Gabriele Cerami when I'm not panda. I introduced myself in the mailing list a whil ago | 17:46 |
| flaviof | zhouhan++ | 17:46 |
| blp | panda: OK, pleased to meet you | 17:46 |
| panda | I was able to clear out some bugs from bugzilla, but they are activities that can go unnoticed sometimes | 17:46 |
| panda | especially if they don't require a patch | 17:46 |
| panda | blp: :) | 17:47 |
| panda | anyway, that's it for my update. | 17:47 |
| numans | I can go real quick | 17:47 |
| flaviof | I second what mmichelson said, panda. no worries. Is the patch you are talking about this one: | 17:47 |
| flaviof | #link https://patchwork.ozlabs.org/project/openvswitch/patch/20200710235515.GA998029@localhost/ ? | 17:47 |
| * flaviof sorry numans ! | 17:48 | |
| numans | flaviof, no worries. I can go after you | 17:48 |
| mmichelson | numans, flaviof already went, actually :) | 17:48 |
| flaviof | numans: go ahead, pls. | 17:48 |
| panda | flaviof: yep, it is. | 17:48 |
| numans | Ok. I submitted this small patch series to improve conntrack usage in OVN | 17:48 |
| numans | #link https://patchwork.ozlabs.org/project/openvswitch/list/?series=191630 | 17:48 |
| numans | There were some performance comparisons between OVN kubernetes and the default openshift SDN with openshift deployment | 17:49 |
| numans | and ovn deployment seemed to fair bad. | 17:49 |
| numans | While debugging noticed that we are sending the packet to conntrack many times when a logical switch has ACLs with allow-related and load balancers | 17:50 |
| numans | This patch series should help a bit. | 17:50 |
| numans | I didn't get much time this week on reviews. I have started looking into mmichelson ECMP patches. | 17:50 |
| numans | That's it from me. | 17:51 |
| mmichelson | Thanks. Anybody else? | 17:51 |
| flaviof | numans++ openshift SDN uses OVS directly? | 17:51 |
| numans | flaviof, yes it does. | 17:51 |
| flaviof | ack. ty | 17:52 |
| numans | it also uses iptables via kube proxy for load balancing. | 17:52 |
| zhouhan | numans: is the patch expected to bring it at the same performance level as the other one? | 17:52 |
| numans | zhouhan, it should improve | 17:52 |
| numans | zhouhan, with openshift SDN I see 2 recirculations. with this patch its just 1 recirculation for Pod to Pod traffic | 17:53 |
| zhouhan | numans: ok, just want to confirm there is no other known gap | 17:53 |
| numans | ok. | 17:53 |

| numans | mmichelson, probably I'm the last one to update. | 17:55 |
| mmichelson | numans, ok | 17:55 |
| mmichelson | Well in that case, everyone have a good day/afternoon/evening | 17:55 |
| mmichelson | Bye! | 17:55 |
| numans | Bye | 17:55 |
