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/netlink.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/netlink.h') diff --git a/include/netlink.h b/include/netlink.h index 0a5fde3c..14fcec16 100644 --- a/include/netlink.h +++ b/include/netlink.h @@ -64,6 +64,7 @@ struct netlink_ctx { struct nft_ctx *nft; struct list_head *msgs; struct list_head list; + struct list_head list_bindings; struct set *set; const void *data; uint32_t seqnum; @@ -83,6 +84,7 @@ struct nft_data_linearize { uint32_t len; uint32_t value[4]; char chain[NFT_CHAIN_MAXNAMELEN]; + uint32_t chain_id; int verdict; }; -- cgit v1.2.3
