Title:
iptables incompatibility
Status in linux package in Ubuntu:
Confirmed
Bug description:
After upgrading to linux-image-6.8.0-56-generic my RKE2 based
kubernetes cluster on Ubuntu 24.04.2 LTS started having some problems.
The kubeproxy pods started crashlooping with an error that said
"Failed to execute iptables-restore"
err=<exit status 2: Warning: Extension MARK revision 0 not supported, missing
kernel module?
ip6tables-restore
v1.8.9 (nf_tables): unknown option "--xor-mark"
Bringing the kernel back to linux-image-6.8.0-55-generic immediately solved
the issue. Booting it back to linux-image-6.8.0-56-generic brought it back.
Had to test again to be certain as there was other changes to the cluster in
the last few hours.
cat /proc/version_signature: Ubuntu 6.8.0-55.57-generic 6.8.12
