|---|---|---|
| tryauuum | there is a package python-networking-ovn in ubuntu, it probably provides all the features I need. But it is kind of huge and full of openstack-related things | 07:22 |

| mmichelson | Hi everyone. Time slipped away from me | 17:18 |
| mmichelson | #startmeeting ovn_community_development_discussion | 17:18 |
| openstack | Meeting started Thu Jul 16 17:18:51 2020 UTC and is due to finish in 60 minutes. The chair is mmichelson. Information about MeetBot at http://wiki.debian.org/MeetBot. | 17:18 |
| openstack | Useful Commands: #action #agreed #help #info #idea #link #topic #startvote. | 17:18 |
| openstack | The meeting name has been set to 'ovn_community_development_discussion' | 17:18 |
| mmichelson | I can get things started. | 17:19 |
| mmichelson | I'm finishing up testing a patch that will allow dnat_force_snat and lb_force_snat options to work with dual-stack routers. | 17:19 |
| mmichelson | Planning on submitting the patch to the list as soon as this meeting is done. | 17:20 |
| mmichelson | Also still working on my patch for forcing symmetric replies to incoming traffic on ECMP routes. | 17:20 |
| mmichelson | I've hit a snag there where the ct_commit() command is very restrictive with what you can set ct_label and ct_mark to | 17:20 |
| mmichelson | I can't just do something like ct_commit(ct_label=eth.src) | 17:20 |
| _lore_ | hi all | 17:21 |
| mmichelson | Because "eth.src" isn't an integer. So I need to expand the command to be able to accept tokens instead of just literals. | 17:21 |
| mmichelson | In doing so, I'll also likely expand it to allow for specific chunks of ct_label and ct_mark to be set (i.e. ct_label[0..47]=eth.src) | 17:21 |
| mmichelson | Only other bit of news is that the ovn.org "Releases" section now actually has content on it instead of placeholder text | 17:22 |
| mmichelson | #link https://www.ovn.org/en/releases/ | 17:22 |
| mmichelson | And that's all from me. | 17:23 |
| numans | Hi | 17:23 |
| numans | I can go real quick. | 17:23 |
| numans | Nothing much this week. dceara found an issue yesterday with monitor-all set to true | 17:24 |
| numans | It was the side effect of the I-P patches. | 17:24 |
| *** acidfu has joined #openvswitch | 17:24 | |
| numans | thanks to dceara for finding 3 bugs so far in the I-P patches | 17:25 |
| numans | I submitted the fix and it is merged to master and branch-20.06 | 17:25 |
| numans | I have been working on optimizing the conntrack stuff in ovn. | 17:25 |
| numans | But nothing concrete yet. although I've a WIP RFC patch which is working | 17:25 |
| numans | If some one wants to take a look | 17:26 |
| numans | #link https://github.com/numansiddique/ovn/commit/7fe68a080c1db09c0fcdcad3a1557f9f1ba23534 | 17:26 |
| numans | I couldn't spend much time in reviews this week, | 17:26 |
| numans | That's it from me. | 17:26 |
| mmichelson | Thanks. I should also schedule some review time this week :( | 17:27 |
| *** yamamoto has joined #openvswitch | 17:27 | |
| dceara | numans: thanks for the quick fix for the I-P bug! | 17:28 |
| numans | dceara, thanks for the review :) | 17:28 |
| mmichelson | Who would like to go next? | 17:29 |
| dceara | I have a quick note this week: I played a bit with imaximets's stream record/replay series and it's great! And I really hope we can get it to the state where it can be used as a debugging tool in production. | 17:31 |
| imaximets | dceara, thanks! | 17:32 |
| dceara | I don't know how relevant it is for this meeting but just in case, ovn-heater supports now running the OVN scale tests on CentOS/RHEL platforms too. Thanks to Jianlin Shi! | 17:33 |
| mmichelson | That'll probably be useful for us RH folks :) | 17:33 |
| numans | dceara, may be we can consider moving it under ovn-org/ovn-heater if everyone is fine | 17:33 |
| dceara | numans: sure, if people think it fits there, I'm all for it. | 17:34 |
| mmichelson | +1 from me | 17:34 |
| numans | +1 from me too. may be we can check with zhouhan and if he is fine | 17:35 |
| dceara | numans: mmichelson: I'll bring it up on the mailing list then. | 17:35 |
| numans | sounds good | 17:35 |
| _lore_ | can I go next? | 17:36 |
| dceara | That's it on my side, thanks! | 17:36 |
| _lore_ | dceara: sorry :( | 17:36 |
| dceara | _lore_: no pb :) | 17:37 |
| _lore_ | so this week I started working on this bz: https://bugzilla.redhat.com/show_bug.cgi?id=1847570 | 17:37 |
| openstack | bugzilla.redhat.com bug 1847570 in OVN "[RFE] Add support for BFD from OVN routers to other directly connected L3 devices" [Urgent,New] - Assigned to lorenzo.bianconi | 17:37 |
| _lore_ | the capability to monitor ecmp next hop for HA | 17:37 |
| _lore_ | I found the discussion upstream between tom and zhouhan | 17:38 |
| _lore_ | and I would like to have their opnionion about next steps | 17:38 |
| _lore_ | *opinions | 17:38 |
| _lore_ | as suggested by numans, we can implement bfd monitoring in ovn-controller, using lib/bfd from ovs | 17:39 |
| _lore_ | another approach would be to rely on ovs implementation, but this will trigger the issue about ovs interface to use for monitoring | 17:40 |
| numans | since ovn can't be sure which interface to use, I personally prefer implementing in ovn. | 17:41 |
| _lore_ | and last approch would be to extend svc_monitorning for that, but this would be non rfc compliant | 17:41 |
| mmichelson | _lore_, do you have a link to the discussion between tom and zhouhan? | 17:41 |
| dceara | _lore_: we do something similar for IGMP/MLD, we reuse the OVS library and we implement the protocol in ovn-conroller. | 17:41 |
| _lore_ | uhm, let me look for it | 17:41 |
| numans | mmichelson, _lore_ its actually trozet :) | 17:41 |
| mmichelson | Ah, Tim, not Tom :) | 17:42 |
| _lore_ | mmichelson: sorry :) | 17:42 |
| _lore_ | https://www.mail-archive.com/ovs-discuss@openvswitch.org/msg07197.html | 17:42 |
| mmichelson | _lore_, Thanks! | 17:42 |
| _lore_ | so 2 for first option :) | 17:43 |
| _lore_ | no other opinions?? | 17:45 |
| mmichelson | _lore_, my initial reaction was to use the ovs BFD library in ovn-controller. zhouhan points out a good point that determining the ovn-controller that is responsible for performing the BFD is important | 17:46 |
| _lore_ | yes | 17:46 |
| _lore_ | for the moment I was thinking about running it on the gw_router or node where gw router port is scheduled | 17:47 |
| *** its-surya has quit IRC | 17:48 | |
| _lore_ | ok, I will exmplore the first option | 17:49 |
| _lore_ | that's all from my side | 17:49 |
| _lore_ | thx | 17:49 |
| mmichelson | OK, do we have anyone else? | 17:50 |
| imaximets | I don't have anything OVN specific. Mostly just reviewing things for OVS 2.14 branching. | 17:50 |
| mmichelson | OK. I didn't notice anybody else in here talking. Is it safe to assume we're done? | 17:52 |
| mmichelson | OK, I'll take the silence to assume we're done. By everyone! | 17:53 |
| mmichelson | *Bye | 17:53 |
