fricklerhaleyb: slaweq: we are seeing job failures on gate nodes that are connected via IPv6. I think the critical code is this one https://opendev.org/openstack/devstack/src/branch/master/lib/neutron_plugins/services/l3#L398-L41113:39
fricklerin my local testing, the first sysctl kills the default route via IPv6. the second one will make it reappear, but only once the next RA comes in13:40
*** ociuhandu has quit IRC13:40
fricklerso depending on the timing, tcp sessions may break in the meantime13:40
*** ociuhandu has joined #openstack-neutron13:41
*** yamamoto has joined #openstack-neutron13:43
fricklerthis is an example of the failure, note that - probably due to buffering - the execution of the code segment I showed above doesn't actually show up in the log anymore. https://storage.gra1.cloud.ovh.net/v1/AUTH_dcaab5e32b234d56b626f72581e3644c/zuul_opendev_logs_650/682647/3/check/ironic-standalone-ipa-src/65091a8/job-output.txt13:43
haleybfrickler: does it kill the default route because an address gets removed?13:43
*** tbachman has quit IRC13:44
fricklerhaleyb: no. running "sudo sysctl -w net.ipv6.conf.all.forwarding=1" immediately kills the default route that was installed via RAs13:44
fricklerrunning "sudo sysctl -w net/ipv6/conf/$d/accept_ra=2" will cause the next received RA to reinstall the default route, but that may happen like 30s later only13:45
fricklerat least that's what I see in my local tests13:45
haleybright, RAs are periodic13:45
haleybone thing i'd start with is setting net.ipv6.conf.all.keep_addr_on_down=113:46

haleybdonnyd: right, if this is an interface connected to a provider network, i thought that was the context14:04
fricklerhaleyb: I think the question is to configure it for a neutron router sending RAs towards instances in a tenant network14:04
donnydWell not in my case. I use BGP at my provider router and RA 's should be from the Openstack router14:04

haleybhttps://github.com/torvalds/linux/blob/master/net/ipv6/route.c#L422514:19
haleybrt6_purge_dflt_routers() is the call from the addrconf code when the sysctl is called14:20
donnydjust for curiosity sake, why are these issues being discovered now? Haven't there been v6 providers in the CI for a while?14:22
donnydAnd if so... have jobs been failing on them all along ?14:22
*** macz has quit IRC14:23
fricklerdonnyd: iiuc we haven't had a v6-only provider for like 2 years. and it's also not all jobs failing, seems to be a kind of a race condition.14:24
fricklerdonnyd: maybe also something changed in the way zuul connects to the nodes, making a short outage have more impact14:24
donnydfrickler: makes sense14:25
fricklerhaleyb: o.k., so that code for me seems to be consistent with my testing14:25

kklimondahi, I'm trying to profile long router creation times with ovs ml2 for DVR/HA enabled routes. I'm seeing logs like: ```Finished a router update for 21d587bb-2e1c-486b-86d0-11d851615cc6, update_id 9fb910ff-15b1-4803-aedb-217c5a529f45. Time elapsed: 392.786``` but no idea what is causing that long of a processing time.16:52
kklimondathat happens when I simultanously try to create 50 routers, networks and subnets - API calls are reasonably quick, but the background processing is taking ages16:53
