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.
This patch is joint work by the authors listed below.
