Subject: [PATCH 4.10 22/27] target: Fix VERIFY_16 handling in sbc_parse_cdb
Date: Fri, 24 Mar 2017 18:58:40 +0100	[thread overview]
Message-ID: <20170324151227.371900655@linuxfoundation.org> (raw)
In-Reply-To: <20170324151225.973768798@linuxfoundation.org>

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Max Lohrmann <post@wickenrode.com>

commit 13603685c1f12c67a7a2427f00b63f39a2b6f7c9 upstream.

As reported by Max, the Windows 2008 R2 chkdsk utility expects
VERIFY_16 to be supported, and does not handle the returned
CHECK_CONDITION properly, resulting in an infinite loop.

The kernel will log huge amounts of this error:

kernel: TARGET_CORE[iSCSI]: Unsupported SCSI Opcode 0x8f, sending
CHECK_CONDITION.
