slaweqrelease calendar updates:14:02
slaweqWe just reached Victoria-2 milestone, next one will be in the week of 7th September which is also Feature and Requirements freeze14:02
slaweqso we should now focus on implementation of the BPs which are accepted and scheduled for this cycle14:03
slaweqnext one14:03
slaweqNetworking-midonet - my last call for maintainers email seems that was success14:03
slaweqthere is guy from the Netways company who wants to maintain it still14:04
*** obondarev has joined #openstack-meeting-314:04
amotokireally good news14:04
slaweqfor now I pointed him to sync with yamamoto14:04
slaweqbut I will not start "deprecating" it this cycle14:04
slaweqlets see how it will be14:04
*** yamamoto has joined #openstack-meeting-314:05
amotokiperhaps he needs to sync information including not only networking-midonet but also midonet with yamamoto14:05
slaweqamotoki: yes, I think so14:05
slaweqand I also told him that first step will be probably fix of the networking-midonet's gate jobs14:05
njohnstono/14:05
slaweqwhich I can try to help14:05
bcafarelyes that should be a good test :)14:06
slaweqnow I'm waiting for response from them14:06
slaweqlast announcement from me for today:14:07
slaweqCFP deadline for virtual Open Infrastructure Summit is today: http://lists.openstack.org/pipermail/openstack-discuss/2020-August/016245.html14:07

*** radez has joined #openstack-meeting-314:08
bcafarelin most projects14:09
radezo/ sry was in the wrong meeting room :)14:09
slaweqbcafarel: yes, thx for the heads up14:09
slaweqso if Your patch failed on the lower-constraints job, please don't recheck yet - it will not help for sure14:10
slaweqradez: welcome14:10
slaweqbtw. radez is our new squad member in RH and he is starting working on Neutron now14:10
slaweq:)14:10
amotokibcafarel: it looks like pip behavior has been changed somehow.... pip seems to check requirement inconsistency but we need more detali check14:10
radezHello everyone14:10
ralonsohbtw, now we have a problem with grenade jobs14:10
ralonsohjust another heads-up14:10
bcafarel:'(14:10
lajoskatonaralonsoh: I've seen that, but personally I never debugged grenade....14:11
bcafarelralonsoh: because we have lower-constraints issue also in stable branches, or another issue?14:11
ralonsohother issue14:12
ralonsohan example: https://026716e2072b41f3360b-f5b932bfaec6245f8b3ddc87df48d7a4.ssl.cf2.rackcdn.com/640258/23/check/neutron-grenade-multinode/bcc8e1e/job-output.txt14:12
slaweqseems like some issue with OSC syntax: https://026716e2072b41f3360b-f5b932bfaec6245f8b3ddc87df48d7a4.ssl.cf2.rackcdn.com/640258/23/check/neutron-grenade-multinode/bcc8e1e/controller/logs/grenade.sh_log.txt ?14:14
slaweqor with nova's _get_inventory_value function14:14
slaweqralonsoh: do You know if that is reported somewhere?14:14
slaweqas it doesn't seems like neutron related problem14:15
ralonsohslaweq, no, I'm still investigating14:15
ralonsohI'll ping Nova folks14:15
amotokiplacement project provides OSC plugin14:15
slaweqralonsoh: thx14:15
ralonsohand I'll open a LP bug just to track it14:15
amotokiI wonder something is changed....14:15
toskyI think they should see the same issue; have you checked their grenade jobs?14:15
ralonsohstill checking14:16
amotokiit looks like nova grenade job is failing for example https://review.opendev.org/#/c/743319/14:17
*** yamamoto has quit IRC14:17
ralonsohbut not in current zuul jobs14:17
slaweqbut it seems for me that nova grenade jobs are failing on some other issue14:18
lajoskatonaI checked and the rp uuid is missing before the VCPU class name14:18
slaweqralonsoh: please open LP for that and we can discuss it later also14:18
ralonsohsure14:18
slaweqand lets move on here with the agenda14:18
slaweq#topic Blueprints14:19
*** openstack changes topic to "Blueprints (Meeting topic: networking)"14:19
slaweqI updated list of our BPs for Victoria-3: https://launchpad.net/neutron/+milestone/victoria-314:19
slaweqdo You have any updates about any of them?14:19
rubasovI'm working on some tempest (or neutron-tempest-plugin) tests for metadata-ipv614:21
slaweqrubasov: thx, that would be great14:21
slaweqI still need to review Your opened patches14:21
rubasovthank you in advance14:21
slaweqand others, please review them too: https://review.opendev.org/#/q/topic:metadata-ipv6+(status:open+OR+status:merged)14:22
rubasovplease note there's a small doc change in nova too14:22
rubasovbecause that's where we have metadata end-user docs14:22
slaweqrubasov: sure14:23
rubasovthat's all from me14:23
slaweqit has the same topic so is in the list already14:23
slaweqmlavalle: I have a question to You about https://blueprints.launchpad.net/neutron/+spec/dns-records-in-neutron14:24
slaweqdid You talk with hamza to check if we can mark it as done?14:24
mlavalleslaweq: yes, we can14:25
slaweqmlavalle: thx14:25
mlavalleI think I mentioned it to you last week in the channel14:25
slaweqYou said that You will ask hamza if there is for sure nothing else todo there :)14:25
mlavallecool14:27
*** Luzi has quit IRC14:27
slaweqI will try next week to focus on https://blueprints.launchpad.net/neutron/+spec/enginefacade-switch also as there is no a lot of patches to do14:27
slaweqralonsoh: I also have a question about https://bugs.launchpad.net/neutron/+bug/188848714:28
openstackLaunchpad bug 1888487 in neutron "Change the default value of "propagate_uplink_status" to True" [Wishlist,In progress] - Assigned to Rodolfo Alonso (rodolfo-alonso-hernandez)14:28
* bcafarel remembers he said he would try to help there too...14:28
slaweqis the neutron-lib patch which You send the only one needed? or some changes on neutron's side will be needed too?14:28
ralonsohboth14:28
ralonsohlet me write the changes14:28
ralonsohhttps://review.opendev.org/#/q/topic:bug/1888487+(status:open+OR+status:merged)14:28
slaweqralonsoh: ok, thx for the link14:30
slaweqhere it should be easy as both patches are small so easy to review :)14:30
slaweqany other updates about BPs today?14:30
slaweqor can we move on?14:30
slaweqok, so lets move on14:32
slaweq#topic Community Goals14:32
*** openstack changes topic to "Community Goals (Meeting topic: networking)"14:32
slaweqlast week I made some progress with "Migrate CI/CD jobs to new Ubuntu LTS Focal"14:32
slaweqI was debugging failures in our functional/fullstack jobs and I found that there were mostly 2 issues:14:33
*** psachin has quit IRC14:33
slaweq1. missing ncat package on the test node,14:33
slaweq2. problem with ebtables-nft which is used by default and which don't supports filtering by IP address in arp filtering rules14:33
slaweqfor 1. I added installation of the ncat package simply and it is fine14:34
slaweqfor 2. I added playbook to switch to ebtables-legacy and that solved the issue for us14:34
slaweqpatches are https://review.opendev.org/#/c/734304/ and https://review.opendev.org/#/c/744500/14:34
slaweqneutron-tempest-dvr-ha-multinode-full job switch https://review.opendev.org/737370 looks ok - this job is passing14:35
slaweqmost of the other jobs should be switched by changes in the tempest jobs definition14:35
slaweqI will sync with gmann about progress there14:35
slaweqanything else You want to add regarding this Ubuntu Focal?14:36
bcafarelyes when I had checked them they all just inherited from tempest or devstack nodeset14:36
bcafarelso should switch by themselves14:36
bcafarelin https://review.opendev.org/738163 dNM patch they should run with Focal14:37
bcafarelalso pep8 will need newer pylint (that supports python 3.8), https://review.opendev.org/#/c/744211/14:37
slaweqthx bcafarel for the updates14:39
slaweqok, lets move on quickly as we have few more items for today14:39
slaweqregarding zuul v3 migration I don't have any updates today14:40
slaweqand I don't think anyone made any progress with that14:40
slaweqso, lets move on to the next topic14:40
slaweq#topic Bugs14:40
*** openstack changes topic to "Bugs (Meeting topic: networking)"14:40
slaweqamotoki was bug deputy14:41
amotokiI just sent my report just before the meeting. sorry for late. http://lists.openstack.org/pipermail/openstack-discuss/2020-August/016290.html14:41
slaweqamotoki: thx for the report14:41
amotokiMost of them are about gate failures and OVN feature gaps.14:41
amotoki Two bugs are not triaged. Both affects neutron behaviors and they are not simple bugs. They need more opinions.14:41
amotokibug 1889631 and bug 188945414:41
openstackbug 1889631 in neutron "[OVS][FW] Multicast non-IGMP traffic is allowed by default, not in iptables FW" [Undecided,New] https://launchpad.net/bugs/188963114:41
openstackbug 1889454 in neutron "br-int has an unpredictable MTU" [Undecided,New] https://launchpad.net/bugs/188945414:41
slaweqyes, bug 1889631 is also added by ralonsoh to the on demand topics14:42
ralonsohabout this one, just the question is14:42
ralonsohshould we block this traffic? by default14:43
ralonsohbecause that was the behaviour in iptables14:43
amotokifrom POV of migration from iptables FW, it should be blocked by default,14:43
ralonsohand we can't add a blocking rule in the FW14:43
amotokibut we already have ovs-fw deployments.14:43
amotokithat's the tricky point14:43
ralonsohagree14:43
ralonsohok, one suggestion14:44
ralonsohthis traffic is allowed by default, as I commented in the bug14:44
ralonsohaccording to  https://tools.ietf.org/html/rfc454114:44
ralonsohcan we add a new knob in the config?14:44
ralonsohto explicitly block this traffic in OVS FW14:44
ralonsoh(by default: current behaviour, not blocking)14:45
amotokibut The config affects the API behavior. this is another tricky point....14:45
ralonsohright: you can write a rule that will affect or not depending on the config14:45
ralonsohbut giving the administrator the ability to enable/disable it, is enough at least from the compatibility point of view14:47
slaweqmy argument for blocking that traffic is that currently user can add rule to explicity allow such kind of traffic and it will work as expected with iptables_hybrid driver but will not work as expected with ovs fw driver14:47
ralonsohyes14:47
amotokione idea is to add a new rule during migration explicitly14:47
ralonsohbut we can have native users14:47
slaweqor even more, it will not work as expected when user will remove the rule14:47
ralonsohthat have never used iptables before14:47
ralonsohnow this traffic will be unexpectedly blocked14:47
slaweqwe can add upgrade check maybe:14:48
slaweqor not, never mind14:48
*** obondarev has quit IRC14:48
ralonsohdo you want to move this conversation to the LP?14:49
amotokiI think it is better.14:49
ralonsohthanks!14:49
slaweqralonsoh: maybe You can also send email about that tot he ML?14:50
ralonsohI'll do it14:50
slaweqthx14:50
amotokiI also had two general questions during triaging bugs.14:50
amotokihte one is about l3-dvr-backlog  tag14:50
amotokiit was originally introduced to identify DVR feature gaps.14:50
amotokido we want some similar tag for OVN L3 feature gaps?14:51
amotokithe other is how should we triage fwaas bugs? I haven't triaged a fwaas bug with neutron tempest plugin yet.14:51
amotokithose are my questions14:52
slaweqabout ovn bugs, IMO "ovn" tag is enough14:52
amotokisounds fair14:52
slaweqI'm not sure if we need any other tag for ovn related things14:52
slaweqand speaking about the fwaas I think the only thing we can do is "best effort" triage as there is no fwaas team anymore14:53
bcafarelso far just "ovn" went fine I think14:53
slaweqI wouldn't treat those fwaas bugs as our top priority TBH14:54
amotokithanks. I already added 'fwaas' tag, so perhaps it would be enough.14:55
slaweqok14:55
slaweqthx amotoki14:55
njohnstonyes I would rate any FWaaS bug as importance 'low'14:55
slaweqregarding 1889454 - please read it and continue discussion in LP14:55
