netfilter: nf_conntrack: prepare namespace support for l3 protocol trackers
This patch prepares the namespace support for layer 3 protocol trackers. Basically, this modifies the following interfaces: * nf_ct_l3proto_[un]register_sysctl. * nf_conntrack_l3proto_[un]register. We add a new nf_ct_l3proto_net is used to get the pernet data of l3proto. This adds rhe new struct nf_ip_net that is used to store the sysctl header and l3proto_ipv4,l4proto_tcp(6),l4proto_udp(6),l4proto_icmp(v6) because the protos such tcp and tcp6 use the same data,so making nf_ip_net as a field of netns_ct is the easiest way to manager it. This patch also adds init_net to struct nf_conntrack_l3proto to initial the layer 3 protocol pernet data. Acked-by: Eric W.
