From 4017a7ee693d1cae6735c0dac21594a7c6416c4c Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Mon, 2 Mar 2015 01:10:28 +0100 Subject: netfilter: restore rule tracing via nfnetlink_log MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since fab4085 ("netfilter: log: nf_log_packet() as real unified interface"), the loginfo structure that is passed to nf_log_packet() is used to explicitly indicate the logger type you want to use. This is a problem for people tracing rules through nfnetlink_log since packets are always routed to the NF_LOG_TYPE logger after the aforementioned patch. We can fix this by removing the trace loginfo structures, but that still changes the log level from 4 to 5 for tracing messages and there may be someone relying on this outthere. So let's just introduce a new nf_log_trace() function that restores the former behaviour.
