Hi Ales,
I see one problem during upgrades. The packet buffering functionality
would be broken when ovn-controllers are updated to the version
which has your patch but ovn-northd is still yet to.
In this case, the below logical flow will be present (without the outer
"output" action)
---
table=21(lr_in_arp_request ), priority=100 , match=(eth.dst ==
00:00:00:00:00:00 && ip4), action=(arp { eth.dst = ff:ff:ff:ff:ff:ff;
arp.spa = reg1; arp.tpa = reg0; arp.op = 1; output; };)
---
The updated ovn-controller will now resume the packet after learning the
nexthop. But this resumed packet will be dropped because there is no
"next" or "output" action following arp {}.
Is this behavior acceptable until ovn-northd is also updated/upgraded ?
Thanks
Numan
