Subject: [PATCH 03/14] Allow binding to non-local addresses if IP_TRANSPARENT is set
Date: Sat, 13 Oct 2007 19:30:31 +0200	[thread overview]
Message-ID: <20071013173031.22517.89002.stgit@nessa.odu> (raw)
In-Reply-To: <20071013172857.22517.84760.stgit@nessa.odu>

Setting IP_TRANSPARENT is not really useful without allowing non-local
binds for the socket. To make user-space code simpler we allow these binds
even if IP_TRANSPARENT is set but IP_FREEBIND is not.
