From 545c93d54d900e8e20071891b7e2bf3bb0e5fed2 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Tue, 6 Jan 2015 21:28:53 +0100 Subject: evaluate: reject: fix dependency generation from nft -f When nft -f is used, ctx->cmd points to the table object, which contains the corresponding chain, set and rule lists. The reject statement evaluator relies on ctx->cmd->rule to add the payload dependencies, which is doesn't point to the rule in that case. This patch adds the rule context to the eval_ctx structure to update the rule list of statements when generating dependencies, as the reject statement needs.
