src: support for implicit chain bindings
This patch allows you to group rules in a subchain, e.g.
table inet x {
chain y {
type filter hook input priority 0;
tcp dport 22 jump {
ip saddr { 127.0.0.0/8, 172.23.0.0/16, 192.168.13.0/24 } accept
ip6 saddr ::1/128 accept;
}
}
}
This also supports for the `goto' chain verdict.
This patch adds a new chain binding list to avoid a chain list lookup from the
delinearize path for the usual chains. This can be simplified later on with a
single hashtable per table for all chains.
From the shell, you have to use the explicit separator ';', in bash you
have to escape this:
# nft add rule inet x y tcp dport 80 jump { ip saddr 127.0.0.1 accept\; ip6 saddr ::1 accept \; }
