2019-04-11netfilter: nf_nat_masquerade: unify ipv4/6 notifier registrationFlorian Westphal
Only reason for having two different register functions was because of ipt_MASQUERADE and ip6t_MASQUERADE being two different modules. Previous patch merged those into xt_MASQUERADE, so we can merge this too. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2019-04-11netfilter: nf_nat: merge ip/ip6 masquerade headersFlorian Westphal
Both are now implemented by nf_nat_masquerade.c, so no need to keep different headers. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2019-03-08netfilter: nat: don't register device notifier twiceFlorian Westphal
Otherwise, we get notifier list corruption. This is the most simple fix: remove the device notifier call chain from the ipv6 masquerade register function and handle it only in the ipv4 version. The better fix is merge nf_nat_masquerade_ipv4/6_(un)register_notifier into a single nf_nat_masquerade_(un)register_notifiers but to do this its needed to first merge the two masquerade modules into a single xt_MASQUERADE. Furthermore, we need to use different refcounts for ipv4/ipv6 until we can merge MASQUERADE.
