From 0bc5399d7723d9ecab5f71c30dcaea4041366446 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Fri, 29 Sep 2017 13:54:21 +0200 Subject: src: add alternate syntax for ct saddr current syntax is: ct original saddr $address problem is that in inet, bridge etc. we lack context to figure out if this should fetch ipv6 or ipv4 from the conntrack structure. $address might not exist, rhs could e.g. be a set reference. One way to do this is to have users manually specifiy the dependeny: ct l3proto ipv4 ct original saddr $address Thats ugly, and, moreover, only needed for table families other than ip or ipv6. Pablo suggested to instead specify ip saddr, ip6 saddr: ct original ip saddr $address and let nft handle the dependency injection. This adds the required parts to the scanner and the grammar, next commit adds code to eval step to make use of this.
