Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next

Pablo Neira Ayuso says:

====================
This is another batch containing Netfilter/IPVS updates for your net-next
tree, they are:

* Six patches to make the ipt_CLUSTERIP target support netnamespace,
  from Gao feng.

* Two cleanups for the nf_conntrack_acct infrastructure, introducing
  a new structure to encapsulate conntrack counters, from Holger
  Eitzenberger.

* Fix missing verdict in SCTP support for IPVS, from Daniel Borkmann.

* Skip checksum recalculation in SCTP support for IPVS, also from
  Daniel Borkmann.

* Fix behavioural change in xt_socket after IP early demux, from
  Florian Westphal.

* Fix bogus large memory allocation in the bitmap port set type in ipset,
  from Jozsef Kadlecsik.

* Fix possible compilation issues in the hash netnet set type in ipset,
  also from Jozsef Kadlecsik.

* Define constants to identify netlink callback data in ipset dumps,
  again from Jozsef Kadlecsik.

* Use sock_gen_put() in xt_socket to replace xt_socket_put_sk,
  from Eric Dumazet.

* Improvements for the SH scheduler in IPVS, from Alexander Frolkin.

* Remove extra delay due to unneeded rcu barrier in IPVS net namespace
  cleanup path, from Julian Anastasov.

* Save some cycles in ip6t_REJECT by skipping checksum validation in
  packets leaving from our stack, from Stanislav Fomichev.

* Fix IPVS_CMD_ATTR_MAX definition in IPVS, larger that required, from
  Julian Anastasov.
