From 1a94e38d254b3622d5d53f74b3b716b0fcab0ba8 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Fri, 10 Feb 2017 12:08:23 +0100 Subject: netfilter: nf_tables: add NFTA_RULE_ID attribute This new attribute allows us to uniquely identify a rule in transaction. Robots may trigger an insertion followed by deletion in a batch, in that scenario we still don't have a public rule handle that we can use to delete the rule. This is similar to the NFTA_SET_ID attribute that allows us to refer to an anonymous set from a batch.
