Pavel Emelyanov d86e0dac2c [NETNS]: Tcp-v6 sockets per-net lookup.
Add a net argument to inet6_lookup and propagate it further.
Actually, this is tcp-v6 implementation of what was done for
tcp-v4 sockets in a previous patch.

Pavel Emelyanov c67499c0e7 [NETNS]: Tcp-v4 sockets per-net lookup.
Add a net argument to inet_lookup and propagate it further
into lookup calls. Plus tune the __inet_check_established.

The dccp and inet_diag, which use that lookup functions
pass the init_net into them.

Pavel Emelyanov 941b1d22cc [NETNS]: Make bind buckets live in net namespaces.
This tags the inet_bind_bucket struct with net pointer,
initializes it during creation and makes a filtering
during lookup.

A better hashfn, that takes the net into account is to
be done in the future, but currently all bind buckets
with similar port will be in one hash chain.

These two functions are the same except for what they call
to "check_established" and "hash" for a socket.

We have INET_MATCH, INET_TW_MATCH and INET6_MATCH to test sockets and
twbuckets for matching, but ipv6 twbuckets are tested manually.

Here's the INET6_TW_MATCH to help with it.

Alexey Dobriyan 025d93d148 [NETFILTER]: x_tables: semi-rewrite of /proc/net/foo_tables_*
There are many small but still wrong things with /proc/net/*_tables_*
so I decided to do overhaul simultaneously making it more suitable for
per-netns /proc/net/*_tables_* implementation.

Fix
a) xt_get_idx() duplicating now standard seq_list_start/seq_list_next
   iterators
b) tables/matches/targets list was chosen again and again on every ->next
c) multiple useless "af >= NPROTO" checks -- we simple don't supply invalid
   AFs there and registration function should BUG_ON instead.

   Regardless, the one in ->next() is the most useless -- ->next doesn't
   run at all if ->start fails.
d) Don't use mutex_lock_interruptible() -- it can fail and ->stop is
   executed even if ->start failed, so unlock without lock is possible.

As side effect, streamline code by splitting xt_tgt_ops into xt_target_ops,
xt_matches_ops, xt_tables_ops.

xt_tables_ops hooks will be changed by per-netns code. Code of
xt_matches_ops, xt_target_ops is identical except the list chosen for
iterating, but I think consolidating code for two files not worth it
given "<< 16" hacks needed for it.

[Patrick: removed unused enum in x_tables.c]

Jan Engelhardt 09e410def6 [NETFILTER]: xt_hashlimit match, revision 1
Introduces the xt_hashlimit match revision 1. It adds support for
kernel-level inversion and grouping source and/or destination IP
addresses, allowing to limit on a per-subnet basis. While this would
technically obsolete xt_limit, xt_hashlimit is a more expensive due
to the hashbucketing.

Kernel-level inversion: Previously you had to do user-level inversion:

	iptables -N foo
	iptables -A foo -m hashlimit --hashlimit(-upto) 5/s -j RETURN
	iptables -A foo -j DROP
	iptables -A INPUT -j foo

now it is simpler:

	iptables -A INPUT -m hashlimit --hashlimit-over 5/s -j DROP

Stephen Hemminger dc64d02ba8 [NETFILTER]: nf_conntrack_h3223: sparse fixes
Sparse complains when a function is not really static. Putting static

Stephen Hemminger 96eb24d770 [NETFILTER]: nf_conntrack: sparse warnings
The hashtable size is really unsigned so sparse complains when you pass
a signed integer.  Change all uses to make it consistent.
