use nf_tables and nf_tables compatibility interface
This patch adds the following utilities: * xtables * xtables-restore * xtables-save * xtables-config They all use Patrick's nf_tables infrastructure plus my compatibility layer. xtables, xtables-restore and xtables-save are syntax compatible with ip[6]tables, ip[6]tables-restore and ip[6]tables-save. Semantics aims to be similar, still the main exception is that there is no commit operation. Thus, we incrementally add/delete rules without entire table locking. The following options are also not yet implemented: -Z (this requires adding expr->ops->reset(...) so nft_counters can reset internal state of expressions while dumping it) -R and -E (this requires adding this feature to nf_tables) -f (can be implemented with expressions: payload 6 (2-bytes) + bitwise a&b^!b + cmp neq 0) -IPv6 support. But those are a matter of time to get them done. A new utility, xtables-config, is available to register tables and chains. By default there is a configuration file that adds backward compatible tables and chains under iptables/etc/xtables.conf. You have to call this utility first to register tables and chains. However, it would be possible to automagically register tables and chains while using xtables and xtables-restore to get similar operation than with iptables.
