[SRU Request] conntrack mark is not advertised via netlink

[Nicolas Dichtel]

Hi Ubuntu kernel team,

the last merge of the v5.15 stable (see
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2003134) has introduced a
bug on netlink netfilter conntrack messages.
The problematic commit is 95fcb42e5f20 ("netfilter: ctnetlink: fix compilation
warning after data race fixes in ct mark"):
https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/jammy/commit/?id=95fcb42e5f20

This bug has been fixed in upstream commit 9f7dd42f0db1 ("netfilter: ctnetlink:
revert to dumping mark regardless of event type"):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9f7dd42f0db1

which has been backported in v5.15.103:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=bef8cf77e21c

Should I open a lanchpad entry to request this backport?
Do you know when the v5.15.103 will be merged in the jammy kernel?

Regards,
Nicolas
