Hi everyone. It's time to begin the weekly OVN developers meeting.
<imaximets>

<numans>
Hello !
<mmichelson>
My short update is that I've been addressing amusil's review feedback on the datapath and port binding sync series. I'm also still making progress on the lflow sync refactor.
<mmichelson>
That's all from me.
<mmichelson>
Who wants to go next?
<imaximets>
I do not have much to report this week. Trying to catch up on some OVS reviews. That's it.
<mmichelson>
Thanks imaximets
<mmichelson>
who's next?
<numans>
I can go next. Unfortunately I'm not able to do much code reviews. Hoping to do some in the next week.
<numans>
Meanwhile I want to check with the community about a new proposal in OVN which I'm working now.
<numans>
We have requirement to program the provider bridge. Instead of doing direct openflow programming, I think it will good for OVN to support logical flow programming for the provider bridges.
<numans>
So I've started working on ovn-pr-controller -> which basically takes logical flows (programmed by CMS) and converts to openflows.
<numans>
Any thoughts on this ? Is it going to be any value ?
<numans>
I'll send out a mail in the ML. Just wanted to check if someone has any thoughts here
<imaximets>
I know ovn-k sets up some wild rules in there to direct traffic between the host and br-int, do you expect your work cover such use cases?
<mmichelson>
What's the difference between ovn-pr-controller and ovn-controller?
<numans>
yes.
<mmichelson>
It sounds like both convert logical flows to openflow.
<numans>
ovn-pr-controller listens to OVN Provider database and just translates logical flows to openflow to the specified bridges ..br-ex, br-provider etc
<numans>
No ovn-northd. It is left to the CMS to decide on the pipeline and define the logical flows.
<numans>
@mmichelson, yes both do. I thought adding the support in ovn-controller to provider bridges could complicate the code in ovn-controller.
<numans>
*to program provider bridges*
<imaximets>
Will it maybe make sense to have a northbound abstraction instead of direct lflow programming?
<numans>
I thought about that. But usecases could differ for each
<numans>
CMS
<numans>
like we want to do natting and maybe run bgp session on provider bridge, learn routes and then program etc. So wanted to give more freedom to the CMS to decide their pipeline
<numans>
We can discuss about it in the ML :) or we can discuss more at the end. If someone wants to update plz go ahead.
<mmichelson>
Yeah I think I'll wait until the proposal hits the ML.
<imaximets>
Yeah, it might be a bit too complicated to cover all the things. That's why provider bridge exists, I guess, and not touched by OVN.
<imaximets>
Makes sense to have a wider discussion on the ML.
<numans>
Ack
<numans>
thanks.
<numans>
That's it from me
<_lore_>
can I go next? quite fast
<mmichelson>
Go right ahead _lore_
<_lore_>
this week I posted a new version to fix the netlink problem of route-exchange IP node
<_lore_>
I added a new stage to trigger the recompute of the node in case of faulire
<_lore_>
*failure
<_lore_>
moreover I posted a new version of the patch to add more debugging info from IP computation addressing Ales's comments
<_lore_>
that's all from my side
<mmichelson>
Thanks _lore_.
<mmichelson>
Does anyone else wish to give an update?
<mmichelson>
Thanks everyone. Have a good day!
<numans>
Bye
<imaximets>
Thanks! Bye.
<mmichelson>
Bye!
