Since 6.6.57, I have the following issue: ip6tables -A INPUT -j NFLOG --nflog-group 1 --nflog-prefix "DROP" Warning: Extension NFLOG revision 0 not supported, missing kernel module? Regarding diff https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/diff/net/netfilter/xt_NFLOG.c?id=v6.6.57&id2=v6.6.56 I wonder if the issue is not related to the change in ipv6 part: + .family = NFPROTO_IPV4, instead of: + .family = NFPROTO_IPV6,
Not my area of expertise, but from a quick look is seems to be a known problem due to some typos and people are working on a fix here: https://lore.kernel.org/all/20241021094536.81487-1-pablo@netfilter.org/
