We need to check which revision type is requested (match, target)
and wheter its ipv4 or ipv6, then set family based on that.
This allows nft ipv6 family to display compat entries if a translation
is available.

Revert commit bce55916b51ec1a4c23322781e3b0c698ecc9561, we need this
code in place to properly make translation when iptables-compat loads
rules.

Initialize structure stmt with stmt_alloc in netlink_parse_target and
netlink_parse_match functions. This patch fixes the gcc warning:
‘stmt’ may be used uninitialized in this function.

Remove functions xt_stmt_alloc(), xt_stmt_release(), xt_stmt_xlate(),
xt_stmt_print(), xt_stmt_destroy() as they are not used. Similarly,
remove structure xt_stmt_ops.

Add nft_init and nft_exit functions, which calls _init and _exit
functions in main.c file. Remove __init and __exit macro definitions as
libnftables library will be created soon. Rename realm_table_init() and
realm_table_exit() functions to avoid ambiguity as
realm_table_rt_init(), realm_table_meta_init, realm_table_rt_exit() and
realm_table_meta_exit() in rt.c and meta.c files.

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.
