From db627ec8a8e72bc6b23dc8ab00f4e6b4f448d01c Mon Sep 17 00:00:00 2001
From: =?UTF-8?q?Timo=20Ter=C3=A4s?= <timo.teras@iki.fi>
Date: Mon, 21 Sep 2015 13:41:58 +0300
Subject: [PATCH 1/3] charon: add optional source and remote overrides for
 initiate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This introduces support for specifying optional IKE SA specific
source and remote address for child sa initiation. This allows
to initiate wildcard connection for known address via vici.

In addition this allows impler implementation of trap-any patches
and is a prerequisite for dmvpn support.
