Subject: [PATCH 4.4 13/20] scsi: sg: Re-fix off by one in sg_fill_request_table()
Date: Tue, 31 Oct 2017 10:55:29 +0100 [thread overview]
Message-ID: <20171031095510.853173349@linuxfoundation.org> (raw)
In-Reply-To: <20171031095510.079198256@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <ben.hutchings@codethink.co.uk>
commit 587c3c9f286cee5c9cac38d28c8ae1875f4ec85b upstream.
Commit 109bade9c625 ("scsi: sg: use standard lists for sg_requests")
introduced an off-by-one error in sg_ioctl(), which was fixed by commit
bd46fc406b30 ("scsi: sg: off by one in sg_ioctl()").
Unfortunately commit 4759df905a47 ("scsi: sg: factor out
sg_fill_request_table()") moved that code, and reintroduced the
bug (perhaps due to a botched rebase). Fix it again.
Fixes: 4759df905a47 ("scsi: sg: factor out sg_fill_request_table()")
