Commit 9335f047fe aka
"[NETFILTER]: ip_tables: per-netns FILTER, MANGLE, RAW"
added per-netns _view_ of iptables rules. They were shown to user, but
ignored by filtering code. Now that it's possible to at least ping loopback,
per-netns tables can affect filtering decisions.
netns is taken in case of
PRE_ROUTING, LOCAL_IN -- from in device,
POST_ROUTING, LOCAL_OUT -- from out device,
FORWARD -- from in device which should be equal to out device's netns.
This code is relatively new, so BUG_ON was plugged.
Wrappers were added to a) keep code the same from CONFIG_NET_NS=n users
(overwhelming majority), b) consolidate code in one place -- similar
changes will be done in ipv6 and arp netfilter code.

Dump the mark value in log messages similar to nfnetlink_log. This
is useful for debugging complex setups where marks are used for
routing or traffic classification.

Patch splits creation of /proc/net/nf_conntrack, /proc/net/stat/nf_conntrack
and net.netfilter hierarchy into their own functions with dummy ones
if PROC_FS or SYSCTL is not set. Also, remove dead "ret = 0" write
while I'm at it.

This expresses __skb_queue_tail() in terms of __skb_insert(),

By rearranging the order of declarations, __skb_dequeue() is expressed in terms of
* skb_peek() and
* __skb_unlink(),
thus in effect mirroring the analogue implementation of __skb_dequeue_tail().

This patches adds a call to increment IPSTATS_MIB_OUTFORWDATAGRAMS
when forwarding the packet in ip6_mr_forward() in the IPv6 multicast
routing module (net/ipv6/ip6mr.c).

The inet6_lookup family of functions requires a net to lookup
a socket in, so give a proper one to them.
No more things to do for dccpv6, since routing is OK and the
ipv4-like transport layer filtering is not done for ipv6.

This call uses the sock to get the net to lookup the routing
in. With CONFIG_NET_NS this code will OOPS, since the sk ptr
is NULL.
After looking inside the ip6_dst_lookup and drawing the analogy
with respective ipv6 code, it seems, that the dccp ctl socket
is a good candidate for the first argument.
