2013-10-14netfilter: nf_tables: Add support for IPv6 NATTomasz Bursztyka1-0/+220
This patch generalizes the NAT expression to support both IPv4 and IPv6 using the existing IPv4/IPv6 NAT infrastructure. This also adds the NAT chain type for IPv6. This patch collapses the following patches that were posted to the netfilter-devel mailing list, from Tomasz: * nf_tables: Change NFTA_NAT_ attributes to better semantic significance * nf_tables: Split IPv4 NAT into NAT expression and IPv4 NAT chain * nf_tables: Add support for IPv6 NAT expression * nf_tables: Add support for IPv6 NAT chain * nf_tables: Fix up build issue on IPv6 NAT support And, from Pablo Neira Ayuso: * fix missing dependencies in nft_chain_nat Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
