Subject[PATCH 4.4 199/312] netfilter: nf_tables: destroy the set if fail to add transaction
Date
From: Liping Zhang <zlpnobody@gmail.com>

commit c17c3cdff10b9f59ef1244a14604f10949f17117 upstream.

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.

Fixes: 958bee14d071 ("netfilter: nf_tables: use new transaction infrastructure to handle sets")
