src: add xt compat support
At compilation time, you have to pass this option. # ./configure --with-xtables And libxtables needs to be installed in your system. This patch allows to list a ruleset containing xt extensions loaded through iptables-compat-restore tool. Example: $ iptables-save > ruleset $ cat ruleset *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -p tcp -m multiport --dports 80,81 -j REJECT COMMIT $ sudo iptables-compat-restore ruleset $ sudo nft list rulseset table ip filter { chain INPUT { type filter hook input priority 0; policy accept; ip protocol tcp tcp dport { 80,81} counter packets 0 bytes 0 reject } chain FORWARD { type filter hook forward priority 0; policy drop; } chain OUTPUT { type filter hook output priority 0; policy accept; } } A translation of the extension is shown if this is available. In other case, match or target definition is preceded by a hash. For example, classify target has not translation: $ sudo nft list chain mangle POSTROUTING table ip mangle { chain POSTROUTING { type filter hook postrouting priority -150; policy accept; ip protocol tcp tcp dport 80 counter packets 0 bytes 0 # CLASSIFY set 20:10 ^^^ } } If the whole ruleset is translatable, the users can (re)load it using "nft -f" and get nft native support for all their rules.
