From 478b360a47b71f3b5030eacd3aae6acb1a32c2b6 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Sat, 15 Feb 2014 23:48:45 +0100 Subject: netfilter: nf_tables: fix nf_trace always-on with XT_TRACE=n When using nftables with CONFIG_NETFILTER_XT_TARGET_TRACE=n, we get lots of "TRACE: filter:output:policy:1 IN=..." warnings as several places will leave skb->nf_trace uninitialised. Unlike iptables tracing functionality is not conditional in nftables, so always copy/zero nf_trace setting when nftables is enabled. Move this into __nf_copy() helper.
