Hi everyone it's time to start the weekly OVN developers' meeting.

I can get things started.

hi
<mmichelson>
I've been working on a couple of ACL-related issues. I hope to have a review up before the end of the week for one that will allow for packets to continue to pass on established sessions even once the ACL no longer matches.
<mmichelson>
After I get that up, I plan to spend at least a day trying to go through patchwork and do some reviews of things that have been up there a while.
<mmichelson>
That's all from me.
<mmichelson>
Who wants to share next?
<fnordahl>
I have an update
<fnordahl>
I've worked some more on the public spec for the BGP feature, and I will review Felix's series. Now that we have sample code for both route learning/sharing I will also work on a plugin interface for this as promised.
<fnordahl>
That's it for me (and I unfortunately need to leave soon as dogs need walking)
<mmichelson>
Thanks for the update fnordahl
<mmichelson>
Who would like to go next?

<imaximets>
Thanks, fnordahl ! Did you have some time to look into ubuntu kernel? :)
<imaximets>
From my side, I don't really have anything OVN-related this week. Did a few reviews. That's it.
<mmichelson>
Thanks for those reviews imaximets
<mmichelson>
Anyone else?
<fnordahl>
imaximets: yes, but not the issue you reported. aparently there are some breakages elsewhere as well, in some vendors drivers, so I'll get to OVS once that's sorted
<imaximets>
fnordahl, ack. No pressure, just checking.
<zhouhan>
maybe fnordahl is walking his dog now :)
<fnordahl>
zhouhan: ah, we've essentially put in a mix of the initial RFC, some temporary patches for bugs that prevent BGP unnumbered from working as well as Felix'es patches to allow routing v4 over v6 next-hop
<zhouhan>
oh haha
<fnordahl>
zhouhan: it is to have a bed to test things in
<mkalcok>
zhouhan: we put together an experiemntal branch in microovn that carries some of the non-released OVN patches
<fnordahl>
ah mkalcok is here to the rescue!
<zhouhan>
thanks mkalcok and fnordahl. Just want to know if it is something worth to look at as a reference implementation
<mkalcok>
yeah, as fnordahl says, it's more like a POC
<fnordahl>
mkalcok: I believe we are looking into how to avoid the register corruption that Numan reported on those patches
<mkalcok>
fnordahl: yes, I started to take a look at patchset proposed by felix some time back regarding IPv4 routes over IPv6 nexthop
<mkalcok>
numan pointed out that in some cases there's a conflicting usage of regs/xregs. But I don't have much to go on yet
<mkalcok>
(that's all from my side)
<fnordahl>
zhouhan: in the end it can serve as a reference implementation, but right now it is experimental as the branch name says
<fnordahl>
zhouhan: we'll probably dive more into it in our talk on the subject on OVS+OVN'24
<zhouhan>
fnordahl: got it. I should say experimental reference implementation :)
<fnordahl>
that has a good ring to it!
<mmichelson>
who all here is planning to be at OVS+OVNcon this year?
<zhouhan>
fnordahl: looking forward to your talk (remotely)
* mmichelson
raises hand
<zhouhan>
mmichelson: I will be remote but my boss and some colleagues are going in person
<mmichelson>
I guess I should have been more specific. I mean, who is going to be there physically, rather than virtually
<mmichelson>
zhouhan, ack, got it.
<mkalcok>
<- in person
* fnordahl
<- and we have one more team member coming as well
<imaximets>
I'll be there.
<mmichelson>
Excellent. I'm looking forward to seeing all of you there.
<mmichelson>
Does anyone else want to share an update for this meeting?
<zhouhan>
I have some quick ones
<mmichelson>
zhouhan, go for it
<zhouhan>
I was looking into an issue of skb_mark(0) match found in DP flows
<zhouhan>
I wonder how was this match introduced. And I didn't see any OVN code introducing it. Does anyone have any idea?
<imaximets>
OVN allows setting pkt_mark, IIRC. And it may match on it in router policies and maybe somewhere else.
<zhouhan>
I did ofproto/trace for the DP flow but it didn't hit any openflow rule that would introduce this match
<zhouhan>
imaximets: ok let me check for pkt_mark. I was searching for skb_mark
<imaximets>
FWIW, it's called pkt_mark in OF.
<zhouhan>
oh, my bad. yes, saw something in northd
<zhouhan>
thanks imaximets
<imaximets>
Another way of use is QoS. If you have QoS, traffic may be marked before sending to queues.
<imaximets>
np
<zhouhan>
I am still reviewing Ales's commit all NAT patch. Have some quick questions but seems Ales is not here?
<mmichelson>
I don't believe he's in here today.
<zhouhan>
I will send to ML then.
<zhouhan>
That's it for me
<mmichelson>
OK thanks zhouhan.
<mmichelson>
Does anyone else wish to give an update?
<mmichelson>
I think that's everyone. Thanks, and have a great day!
<mmichelson>
Bye!
<mkalcok>
