<mmichelson> Hi everyone it's time to start the weekly OVN developers' meeting.
<fnordahl> o/
mkalcok has joined #openvswitch
<mmichelson> I can get things started.

<zhouhan> 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?
ChmEarl has joined #openvswitch
<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
<zhouhan> fnordahl: I saw this accidentally: https://github.com/canonical/microovn/pull/182 . Do you know what's the status and relationship with the ongoing BGP patches.
<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> \o bye
