Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next
Pablo Neira Ayuso says: ==================== The following batch contains Netfilter/IPVS updates for net-next, they are: * Enforce policy to several nfnetlink subsystem, from Daniel Borkmann. * Use xt_socket to match the third packet (to perform simplistic socket-based stateful filtering), from Eric Dumazet. * Avoid large timeout for picked up from the middle TCP flows, from Florian Westphal. * Exclude IPVS from struct net if IPVS is disabled and removal of unnecessary included header file, from JunweiZhang. * Release SCTP connection immediately under load, to mimic current TCP behaviour, from Julian Anastasov. * Replace and enhance SCTP state machine, from Julian Anastasov. * Add tweak to reduce sync traffic in the presence of persistence, also from Julian Anastasov. * Add tweak for the IPVS SH scheduler not to reject connections directed to a server, choose a new one instead, from Alexander Frolkin. * Add support for sloppy TCP and SCTP modes, that creates state information on any packet, not only initial handshake packets, from Alexander Frolkin. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
