I did a quick test and for new connection the cgroup2 match worked as
expected. For an existing connection I wasn't able to trigger the match.

It is quite likely I do something wrong:

ssh into the box
# mkdir /sys/fs/cgroup/test
# echo $$ > /sys/fs/cgroup/test/cgroup.procs
# echo $PPID > /sys/fs/cgroup/test/cgroup.procs
# iptables -A OUTPUT -m cgroup --path test

Should I see matches with the existing ssh session?
