| mmichelson | Hi everyone. I'm going to start the meeting a touch early. | 17:15 |

| _lore_ | hi all | 17:15 |
| mmichelson | Hi everyone. NOt sure who all is here today, but I can give a brief update | 17:16 |
| zhouhan | Hi | 17:16 |
| dceara | Hi | 17:17 |
| mmichelson | I sent out an email last week announcing a soft freeze for OVN 20.09.0 for 11 September. So far I haven't got any replies for specific patches that people would like in that release. I've spent the week looking at what appear to be the most impactful patches, as well as the ones that are easiest to get merged. | 17:17 |
| mmichelson | I have a few more patches in my queue, but if anyone has specific ones they want in 20.09.0, please send a response to my email. | 17:18 |
| dceara | mmichelson: I have a couple, I'll reply to your email. | 17:18 |
| mmichelson | dceara, thanks! | 17:19 |
| mmichelson | complicating matters, I'm going to be out starting Monday for 2 weeks. So someone will need to volunteer to create the 20.09 branch once we have patches merged after the soft freeze. | 17:19 |
| mmichelson | I'll be back on 28 September, so I can actually push the release out when I get back. | 17:20 |
| mmichelson | And that's all from me | 17:21 |
| zhouhan | Thanks mmichelson. I can have quick update. | 17:22 |
| zhouhan | I got my i-p flow installation series and nbcfg measurement improvement series merged. Thanks mmichelson and numans for the reivews! | 17:23 |
| zhouhan | I will do some more reviews this week. | 17:24 |
| zhouhan | That's my update. | 17:24 |
| _lore_ | can I go next? very quick update also from me | 17:24 |
| zhouhan | _lore_: sure | 17:24 |
| _lore_ | this week I worked mainly downstream backporting upstream fixes | 17:24 |
| numans | Hello | 17:24 |
| _lore_ | then I resumed my iPXE work rebasing my old patch | 17:25 |
| _lore_ | the I started working on ovn-scale-test to run switch_per_node task in a single iteration to reuse the ssh connection | 17:25 |
| _lore_ | *then | 17:25 |
| _lore_ | the main issue there is the time estimation done by rally since w the current code it is performed per iteration | 17:26 |
| _lore_ | dceara suggested we can use a new feature in rally called like merge_atomic_timer that should merge timer w the same name | 17:26 |
| _lore_ | but it require to upgrade rally (out current version in quite old, like 5y) | 17:27 |
| *** dmellado has quit IRC | 17:27 | |
| _lore_ | so we need to understand explore this | 17:27 |
| _lore_ | zhouhan: even your version is quite old, right? | 17:27 |
| zhouhan | _lore_: yes, I think so. | 17:28 |
| _lore_ | I guess is aligned with our version more or less | 17:29 |
| _lore_ | have you ever tried to update it? | 17:29 |
| zhouhan | _lore_: I can remember clearly but just followed the document of ovn-scale-test to install | 17:29 |
| zhouhan | s/can/can't | 17:29 |
| _lore_ | from jakub? | 17:29 |
| zhouhan | _lore_: from ovn-scale-test repo | 17:30 |
| _lore_ | ok | 17:31 |
| _lore_ | then I will look into it | 17:31 |
| zhouhan | _lore_: and I never tried updating once it worked. So please explore and update the document for the steps if there is any change. | 17:31 |
| _lore_ | last I have a pending ovs-raft patch waiting for reviews | 17:31 |
| _lore_ | zhouhan: ack, will do | 17:31 |
| zhouhan | _lore_: thanks! could you remind the ovs-raft patch link if you have it? | 17:32 |
| _lore_ | I trying to open ovs patchwork | 17:32 |
| _lore_ | :) | 17:32 |
| _lore_ | but it seems very slow | 17:32 |
| zhouhan | _lore_: ok :) | 17:32 |
| _lore_ | not sure why | 17:32 |
| _lore_ | zhouhan: "[PATCH v2] ovsdb: raft: add some debugging information to cluster/status command" | 17:33 |
| _lore_ | I do not have the link at the moment | 17:33 |
| numans | _lore_, yeah looks like patchworks is slow | 17:33 |
| zhouhan | _lore_: I see. thanks! | 17:34 |
| numans | or down I think | 17:34 |
| _lore_ | that's all from my side | 17:34 |
| _lore_ | thx | 17:34 |
| imaximets | #link https://patchwork.ozlabs.org/project/openvswitch/patch/95b2a271bc6f04b91bed76847b70359b4234eeef.1599127790.git.lorenzo.bianconi@redhat.com/ | 17:34 |
| imaximets | patchwork is not responsive for some reason. | 17:35 |
| numans | I can go real quick next | 17:36 |
| numans | I spent much of this week on reviews. Thanks to mmichelson and the patchworks, it is much easier to find the ovn patches and to review. | 17:36 |
| numans | I also addressed comments from mmichelson for the expr cache patch series. | 17:37 |
| numans | and I applied it today. | 17:37 |
| numans | I'm also looking into some ovn issues seen in openshift deployments | 17:38 |
| numans | mmichelson, thanks for the reviews. | 17:38 |
| numans | That's it from me. | 17:38 |
| dceara | I have a brief update too. | 17:39 |
| dceara | I sent a few patches trying to make Chassis/Chassis_private processing work when the system-id changes. But as pointed by numans and zhouhan there's no bullet proof way to support this without external help from operators. I'll send a patch to properly document this and cleanup the chassis.c code. | 17:40 |
| dceara | I also sent a patch today to add a "default conflict resolution" behavior when we have multiple openflows with the same match and different actions. This is needed to avoid inconsistent behaviors when users configure overlapping ACLs (I know it's a misconfig but sometimes it can't be avoided easily) | 17:42 |
| dceara | #link http://patchwork.ozlabs.org/project/ovn/patch/1599743157-13626-1-git-send-email-dceara@redhat.com/ | 17:42 |
| mmichelson | dceara, I'm planning to give that a look today | 17:43 |
| dceara | Last thing is the series I sent last week for bypassing conntrack, it might not be worth merging patch 2/2 because it conflicts with numans' fix for load balancers but the first patch can be applied independently and optimizes openflow count for ACLs (as suggested by zhouhan) | 17:44 |
| dceara | #link http://patchwork.ozlabs.org/project/ovn/list/?series=199101 | 17:44 |
| dceara | That's it from me this week. Thanks! | 17:44 |
| dceara | mmichelson: thanks! | 17:44 |
| zhouhan | dceara: thanks. I am looking at the "default conflict resolution" patch, and have some comments. | 17:45 |
| dceara | zhouhan: sure, do you want to discuss here or on the mailing list? | 17:45 |
| zhouhan | dceara: let me reply in ML | 17:46 |
| *** dmellado has joined #openvswitch | 17:46 | |
| dceara | zhouhan: ok, thanks | 17:46 |
| *** ohama has quit IRC | 17:46 | |
| mmichelson | OK, does anybody else have an update to give? | 17:47 |
| *** ohama has joined #openvswitch | 17:47 | |
| mmichelson | All right, I guess that's everyone then | 17:50 |
| zhouhan | dceara: just replied :) | 17:50 |
| mmichelson | Have a good day/evening/morning everyone. As I mentioned, I'll be out the next two weeks. Bye | 17:50 |
| zhouhan | bye everyone! | 17:50 |
