Summary
In addition to a whole lot of dependency updates. The major update here is re-adding the missing ip6tables binary that was accidentally removed when we reverted Alpine 3.19 -> Alpine 3.18 as part of the v2.1.X line of releases.
Additionally, this also fixes a number of issues with IPv6 where there was:
- Some hard-coded
/32netmasks still in the code - Specific
IPv4families hard-coded when looking for local interfaces - Missing allowances for ICMPv6 neighbor discovery when network policies were applied
- An issue where bogus IPv6 routes were being added when service VIPs were added to the kube-dummy-if interface, causing traffic from the same node to no longer be able to route
Contributions
Thanks @ncopa and @mrueg for contributing to this release!
Also a big thanks to @k6av for reporting some critical issues with IPv6 support.
