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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
