From ec2c9935688fbd5eaa7c975e3e21562c3da77363 Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 5 Feb 2014 15:03:35 +0000 Subject: [PATCH] netfilter: nf_tables: fix potential oops when dumping sets Commit c9c8e48597 (netfilter: nf_tables: dump sets in all existing families) changed nft_ctx_init_from_setattr() to only look up the address family if it is not NFPROTO_UNSPEC. However if it is NFPROTO_UNSPEC and a table attribute is given, nftables_afinfo_lookup() will dereference the NULL afi pointer. Fix by checking for non-NULL afi and also move a check added by that commit to the proper position. Signed-off-by: Patrick McHardy Signed-off-by: Pablo Neira Ayuso --- Reading git-format-patch failed
