Subject: [PATCH/RFC 07/13] Conditionally enable transparent flow flag when connecting
Date: Mon, 05 Mar 2007 16:46:01 +0100	[thread overview]
Message-ID: <20070305154601.3471.968.stgit@nienna.balabit> (raw)
In-Reply-To: <20070305154451.3471.18396.stgit@nienna.balabit>

Set FLOWI_FLAG_TRANSPARENT in flowi->flags if the socket has the
transparent socket option set. This way we selectively enable certain
connections with non-local source addresses to be routed.
