Description Markus Armbruster 2011-11-25 10:29:46 UTC

Description of problem:
Computation of SCSI request lengths is buggy for values exceeding 31 bits (unwanted sign extension).  Such lengths are not expected to occur in practice, especially not with usb-storage, which is our only SCSI device.  Let's fix it anyway.

How reproducible:
Theoretical bug, not actually reproduced

Fixed upstream in commit bd5da23265ba3bb11a9f0913e016e3c3a16abf8e.
