Subject: [PATCH] ip: update the description of rp_filter in ip-sysctl.txt
Date: Tue, 01 Dec 2009 15:04:32 +0800 [thread overview]
Message-ID: <4B14C000.3090608@cn.fujitsu.com> (raw)
The commit 27fed4175acf81ddd91d9a4ee2fd298981f60295
（ip: fix logic of reverse path filter sysctl）has changed the logic of rp_filter.
The document about rp_filter is out of date. Now, setting conf/all/rp_filte with 0
can also enable source validation.
Update the document according to the commit.
