The function signatures for Xtables extensions have grown over time. It involves a lot of typing/replication, and also a bit of stack space even if they are not used. Realize an NFWS2008 idea and pack them into structs. The skb remains outside of the struct so gcc can continue to apply its optimizations. This patch does this for match extensions' match functions. A few ambiguities have also been addressed. The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).

ip6t_LOG does certainly not depend on the filter table. (Also, move it so that menuconfig still displays it correctly.) Signed-off-by:

It used to be that {ip,ip6,etc}_tables called extension->checkentry themselves, but this can be moved into the xtables core. Signed-off-by: -

Usually -EINVAL is used when checkentry fails (see *_tables). Signed-off-by:

Ebtables ORs (1 << NF_BR_NUMHOOKS) into the hook mask to indicate that the extension was called from a base chain. So this also needs to be present in the extensions' ->hooks. Signed-off-by:

It is a mask, and masks are most useful in hex. Signed-off-by:

The function signatures will be changed to match those of Xtables, and the datalen argument will be gone. ebt_among unfortunately relies on it, so we need to obtain it somehow. Signed-off-by:

The TPROXY target implements redirection of non-local TCP/UDP traffic to local sockets. Additionally, it's possible to manipulate the packet mark if and only if a socket has been found. (We need this because we cannot use multiple targets in the same iptables rule.) Signed-off-by:

Add iptables 'socket' match, which matches packets for which a TCP/UDP socket lookup succeeds. Signed-off-by:

The iptables tproxy core is a module that contains the common routines used by various tproxy related modules (TPROXY target and socket match) Signed-off-by:

Netfilter connection tracking requires all IPv4 packets to be defragmented. Both the socket match and the TPROXY target depend on this functionality, so this patch separates the Netfilter IPv4 defrag hooks into a separate module. Signed-off-by:

From kernel perspective, allow entrance in nf_hook_slow(). Stuff which uses nf_register_hook/nf_register_hooks, but otherwise not netns-ready: DECnet netfilter ipt_CLUSTERIP nf_nat_standalone.c together with XFRM (?) IPVS several individual match modules (like hashlimit) ctnetlink NOTRACK all sorts of queueing and reporting to userspace L3 and L4 protocol sysctls, bridge sysctls probably something else Anyway critical mass has been achieved, there is no reason to hide netfilter any longer. From userspace perspective, allow to manipulate all sorts of iptables/ip6tables/arptables rules. Signed-off-by:

Add init_net checks to not remove kmem_caches twice and so on. Refactor functions to split code which should be executed only for init_net into one place. ip_ct_attach and ip_ct_destroy assignments remain separate, because they're separate stages in setup and teardown. NOTE: NOTRACK code is in for-every-net part. It will be made per-netns after we decidce how to do it correctly. Signed-off-by:
