From 5b023fc8d8e0997e0b7ea6506d243afd5478c96e Mon Sep 17 00:00:00 2001 From: Gao feng Date: Fri, 5 Apr 2013 17:04:35 +0200 Subject: [PATCH] netfilter: enable per netns support for nf_loggers After this patch, all nf_loggers support net namespace. Still xt_LOG and ebt_log require syslog netns support.
