====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next
tree. This batch contains connection tracking updates for the cleanup
iteration path, patches from Florian Westphal:

X) Skip unconfirmed conntracks in nf_ct_iterate_cleanup_net(), just set
   dying bit to let the CPU release them.

X) Add nf_ct_iterate_destroy() to be used on module removal, to kill
   conntrack from all namespace.

X) Restart iteration on hashtable resizing, since both may occur at
   the same time.

X) Use the new nf_ct_iterate_destroy() to remove conntrack with NAT
   mapping on module removal.

X) Use nf_ct_iterate_destroy() to remove conntrack entries helper
   module removal, from Liping Zhang.

X) Use nf_ct_iterate_cleanup_net() to remove the timeout extension
   if user requests this, also from Liping.

X) Add net_ns_barrier() and use it from FTP helper, so make sure
   no concurrent namespace removal happens at the same time while
   the helper module is being removed.

X) Use NFPROTO_MAX in layer 3 conntrack protocol array, to reduce
   module size. Same thing in nf_tables.

Updates for the nf_tables infrastructure:

X) Prepare usage of the extended ACK reporting infrastructure for
   nf_tables.

X) Remove unnecessary forward declaration in nf_tables hash set.

X) Skip set size estimation if number of element is not specified.

X) Changes to accomodate a (faster) unresizable hash set implementation,
   for anonymous sets and dynamic size fixed sets with no timeouts.

X) Faster lookup function for unresizable hash table for 2 and 4
   bytes key.

And, finally, a bunch of asorted small updates and cleanups:

X) Do not hold reference to netdev from ipt_CLUSTER, instead subscribe
   to device events and look up for index from the packet path, this
   is fixing an issue that is present since the very beginning, patch
   from Xin Long.

X) Use nf_register_net_hook() in ipt_CLUSTER, from Florian Westphal.

X) Use ebt_invalid_target() whenever possible in the ebtables tree,
   from Gao Feng.

X) Calm down compilation warning in nf_dup infrastructure, patch from
   stephen hemminger.

X) Statify functions in nftables rt expression, also from stephen.

X) Update Makefile to use canonical method to specify nf_tables-objs.
   From Jike Song.

X) Use nf_conntrack_helpers_register() in amanda and H323.

X) Space cleanup for ctnetlink, from linzhang.
