From c330152b7f7779f15dba3e0862bf5616e7cb3eab Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Sat, 4 Jul 2020 02:43:44 +0200 Subject: 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 \; } Signed-off-by: Pablo Neira Ayuso --- include/expression.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/expression.h') diff --git a/include/expression.h b/include/expression.h index 87937a50..0210a3cb 100644 --- a/include/expression.h +++ b/include/expression.h @@ -249,6 +249,7 @@ struct expr { /* EXPR_VERDICT */ int verdict; struct expr *chain; + uint32_t chain_id; }; struct { /* EXPR_VALUE */ -- cgit v1.2.3
