From ca7cd666949b68bf41a32de38ee38e332e89863b Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Mon, 11 Feb 2008 01:23:01 +0100
Subject: Add all necessary header files - compilation fix for various cases

Allow iptables to compile without a kernel source tree. This
implies fixing build for older kernels, such as 2.6.17 which
lack xt_SECMARK.h.
