Title:
conntrack mark is not advertised via netlink
Status in linux package in Ubuntu:
Incomplete
Bug description:
[Impact]
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
[Test Case]
Run 'conntrack -E' and check the output.
Before the problematic commit:
> tcp 6 2 ESTABLISHED src=10.100.0.1 dst=10.200.0.1 sport=6789
dport=12345 src=10.200.0.1 dst=10.100.0.1 sport=12345 dport=6789 [ASSURED]
mark=0 use=1
'mark=' is seen on connrtack event
after:
> tcp 6 2 ESTABLISHED src=10.100.0.1 dst=10.200.0.1 sport=6789
dport=12345 src=10.200.0.1 dst=10.100.0.1 sport=12345 dport=6789 [ASSURED] use=1
=> 'mark=' is not seen.
[Regression Potential]
The patch is quite simple. It has been backported in the official 5.15
stable. The risk of regression should be contained.
