Hi Numan,

is the patch accepted on upstream? and could you give some suggestions on how to reproduce the issue? thanks

Comment 6 Numan Siddique 2022-04-23 18:29:14 UTC
@Jianlin Shi - No.  It is not merged yet. 

The issue is not the packet loss here.  It is just that the packet is sent to conntrack an extra time.

The patch is on hold as it is breaking some scenarios.

Hi Einat

I took over this issue, and hope to propose today or tomorrow some potential fix for it.
The fix will not prevent all the possible extra commits, but should remove some, when possible.
Thanks
Xavier

Marking this issue as "CLOSED". This issue has ovn-2021 as the component, but we aren't applying this change to ovn-2021. Instead, the cloned issues linked by OVN bot in the previous comment have the components correctly set where the issue is fixed. Those issues are marked as "MODIFIED" and will go through the proper errata process.
