From: Steven Barth Date: Thu, 7 Aug 2014 04:42:22 +0000 (+0000) Subject: iptables: NFLOG and NFQUEUE targets' full support X-Git-Tag: reboot~6307 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9f2a17103fc93ccc6d205ef824f5067f494a41b3;p=openwrt%2Fstaging%2Flynxis.git iptables: NFLOG and NFQUEUE targets' full support NFLOG and NFQUEUE targets' full support for iptables. Includes all needed kernel modules (Xtables's and Netlink's) and userspace libraries. All added kernel modules can be individually disabled, all other new libraries get their own individual packages.
