Subject: [PATCH 4.0-testing 05/10] VT-d: fix interrupt remapping source validation for devices behind legacy bridges
Date: Mon, 11 Feb 2013 13:12:48 +0000 [thread overview]
Message-ID: <1360588373-779-5-git-send-email-ian.campbell@citrix.com> (raw)
In-Reply-To: <1360588355.20449.34.camel@zakaz.uk.xensource.com>
From: Jan Beulich <jbeulich@suse.com>
Using SVT_VERIFY_BUS here doesn't make sense; native Linux also
uses SVT_VERIFY_SID_SQ here instead.
This is XSA-33 / CVE-2012-5634.
Signed-off-by: Jan Beulich <jbeulich@suse.com>
