From c17c3cdff10b9f59ef1244a14604f10949f17117 Mon Sep 17 00:00:00 2001 From: Liping Zhang Date: Sat, 29 Oct 2016 22:03:05 +0800 Subject: [PATCH] netfilter: nf_tables: destroy the set if fail to add transaction When the memory is exhausted, then we will fail to add the NFT_MSG_NEWSET transaction. In such case, we should destroy the set before we free it.
