+Subject: [PATCH 23/33] glx: Fix image size computation for
+ EXT_texture_integer [CVE-2014-8098 1/8]
+
+Without this we'd reject the request with BadLength.  Note that some old
+versions of Mesa had a bug in the same place, and would _send_ zero
+bytes of image data; these will now be rejected, correctly.
