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/parser.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'include/parser.h') diff --git a/include/parser.h b/include/parser.h index 636d1c88..9baa3a4d 100644 --- a/include/parser.h +++ b/include/parser.h @@ -11,7 +11,7 @@ #define YYLTYPE_IS_TRIVIAL 0 #define YYENABLE_NLS 0 -#define SCOPE_NEST_MAX 3 +#define SCOPE_NEST_MAX 4 struct parser_state { struct input_descriptor *indesc; -- cgit v1.2.3
