Subject: [PATCH 03/13] Allow binding to non-local addresses if IP_TRANSPARENT is set
Date: Tue, 02 Oct 2007 22:41:15 +0200 [thread overview]
Message-ID: <20071002204115.11052.26660.stgit@nessa.odu> (raw)
In-Reply-To: <20071002203942.11052.7303.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.
