Description Casey Callendrello 2021-04-07 20:21:03 UTC

Upstream PR https://github.com/ovn-org/ovn-kubernetes/pull/2152 fixes a bug where ForEachAddressSet didn't work.

This means that we won't delete old address sets if the deletion is missed, say, because ovn-k was restarting.

If another namespace or NetworkPolicy comes into existence with the same name, it will have spurious IPs in the address set.

We should backport this fix as appropriate.
