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

Pablo Neira Ayuso says:

====================
The following patchset contains two Netfilter fixes for your net
tree, they are:

* Fix endianness in nft_reject, the NFTA_REJECT_TYPE netlink attributes
  was not converted to network byte order as needed by all nfnetlink
  subsystems, from Eric Leblond.

* Restrict SYNPROXY target to INPUT and FORWARD chains, this avoid a
  possible crash due to misconfigurations, from Patrick McHardy.
