From b66985b11b8b00e1ec65b89a3112510ac9a9ec6e Mon Sep 17 00:00:00 2001 From: Eric Leblond Date: Wed, 11 Jun 2008 17:50:27 -0700 Subject: [PATCH] netfilter: Make nflog quiet when no one listen in userspace. The message "nf_log_packet: can't log since no backend logging module loaded in! Please either load one, or disable logging explicitly" was displayed for each logged packet when no userspace application is listening to nflog events. The message seems to warn for a problem with a kernel module missing but as said before this is not the case. I thus propose to suppress the message (I don't see any reason to flood the log because a user application has crashed.)
