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