This is a 2.4 backport of a linux-2.6 change by Alan Cox.
(commit 60395bb60e0b5e4e0808ac8eb07a92f6c9cdea1f)
It has been build-tested only (I don't have the hardware).
CVE-2007-4308 was assigned for this issue.
Commit log from 2.6 follows.
On the SCSI layer ioctl path there is no implicit permissions check for
ioctls (and indeed other drivers implement unprivileged ioctls). aacraid
however allows all sorts of very admin only things to be done so should
check.
