Subject: [PATCH 4/5] xen pvfb: Zero unused bytes in events sent to backend
Date: Wed, 21 May 2008 10:40:31 +0200 [thread overview]
Message-ID: <871w3wm4n4.fsf@pike.pond.sub.org> (raw)
In-Reply-To: 87d4ngm4s4.fsf@pike.pond.sub.org
This isn't a security flaw (the backend can see all our memory
anyway). But it's the right thing to do all the same.
