From 5f7340eff8f68f41b7e5c7ad47ec4cd1ea1afb40 Mon Sep 17 00:00:00 2001 From: Eric Leblond Date: Tue, 4 Nov 2008 14:21:08 +0100 Subject: netfilter: xt_NFLOG: don't call nf_log_packet in NFLOG module. This patch modifies xt_NFLOG to suppress the call to nf_log_packet() function. The call of this wrapper in xt_NFLOG was causing NFLOG to use the first initialized module. Thus, if ipt_ULOG is loaded before nfnetlink_log all NFLOG rules are treated as plain LOG rules.
