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.
