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

Pablo Neira Ayuso says:

====================
The following patchset contains a small batch of Netfilter
updates for your net-next tree, they are:

* Three patches that provide more accurate error reporting to
  user-space, instead of -EPERM, in IPv4/IPv6 netfilter re-routing
  code and NAT, from Patrick McHardy.

* Update copyright statements in Netfilter filters of
  Patrick McHardy, from himself.

* Add Kconfig dependency on the raw/mangle tables to the
  rpfilter, from Florian Westphal.
====================
