As most ASM1051 based devices, this one has unfixable issues with uas too.

Besides the ASM1051 (*) needing sdev->no_report_opcodes = 1, it turns out that
the JMicron JMS567 also needs it to work properly with uas (usb-storage always
sets it). Since some of the scsi devs were not to keen on the idea to
outrightly set sdev->no_report_opcodes = 1 for all uas devices, so add a quirk
for this, and set it for the JMS567.
*) Which has become a non-issue since we've completely blacklisted uas on
the ASM1051 for other reasons

This patch adds quirks for Entrega Technologies (later Xircom PortGear) USB-
SCSI converters. They use Shuttle Technology EUSB-01/EUSB-S1 chips. The
US_FL_SCM_MULT_TARG quirk is needed to allow multiple devices on the SCSI
chain to be accessed. Without it only the (single) device with SCSI ID 0
can be used.
The standalone converter sold by Entrega had model number U1-SC25. Xircom
acquired Entrega and re-branded the product line PortGear. The PortGear USB
to SCSI Converter (model PGSCSI) is internally identical to the Entrega
product, but later models may use a different USB ID. The Entrega-branded
units have USB ID 1645:0007, as does my Xircom PGSCSI, but the Windows and
Macintosh drivers also support 085A:0028.
Entrega also sold the "Mac USB Dock", which provides two USB ports, a Mac
(8-pin mini-DIN) serial port and a SCSI port. It appears to the computer as
a four-port hub, USB-serial, and USB-SCSI converters. The USB-SCSI part may
have initially used the same ID as the standalone U1-SC25 (1645:0007), but
later production used 085A:0026.
My Xircom PortGear PGSCSI has bcdDevice=0x0100. Units with bcdDevice=0x0133
probably also exist.
This patch adds quirks for 1645:0007, 085A:0026 and 085A:0028. The Windows
driver INF file also mentions 085A:0032 "PortStation SCSI Module", but I
couldn't find any mention of that actually existing in the wild; perhaps it
was cancelled before release?

Hi,
The Ariston Technologies iConnect 025 and iConnect 050 (also known as e.g.
iSCSI-50) are SCSI-USB converters which use Shuttle Technology/SCM
Microsystems chips. Only the connectors differ; both have the same USB ID.
The US_FL_SCM_MULT_TARG quirk is required to use SCSI devices with ID other
than 0.
I don't have one of these, but based on the other entries for Shuttle/
SCM-based converters this patch is very likely correct. I used 0x0000 and
0x9999 for bcdDeviceMin and bcdDeviceMax because I'm not sure which
bcdDevice value the products use.

The SCSI specification requires that the second Command Data Byte
should contain the LUN value in its high-order bits if the recipient
device reports SCSI level 2 or below. Nevertheless, some USB
mass-storage devices use those bits for other purposes in
vendor-specific commands. Currently Linux has no way to send such
commands, because the SCSI stack always overwrites the LUN bits.
Testing shows that Windows 7 and XP do not store the LUN bits in the
CDB when sending commands to a USB device. This doesn't matter if the
device uses the Bulk-Only or UAS transports (which virtually all
modern USB mass-storage devices do), as these have a separate
mechanism for sending the LUN value.
Therefore this patch introduces a flag in the Scsi_Host structure to
inform the SCSI midlayer that a transport does not require the LUN
bits to be stored in the CDB, and it makes usb-storage set this flag
for all devices using the Bulk-Only transport. (UAS is handled by a
separate driver, but it doesn't really matter because no SCSI-2 or
lower device is at all likely to use UAS.)
The patch also cleans up the code responsible for storing the LUN
value by adding a bitflag to the scsi_device structure. The test for
whether to stick the LUN value in the CDB can be made when the device
is probed, and stored for future use rather than being made over and
over in the fast path.

The Iomega Jaz USB Adapter is a SCSI-USB converter cable. The hardware
seems to be identical to e.g. the Microtech XpressSCSI, using a Shuttle/
SCM chip set. However its firmware restricts it to only work with Jaz
drives.
On connecting the cable a message like this appears four times in the log:
reset full speed USB device number 4 using uhci_hcd
That's non-fatal but the US_FL_SINGLE_LUN quirk fixes it.

There are a large numbers of issues with ASM1051 devices in uas mode:
1) They do not support REPORT SUPPORTED OPERATION CODES
2) They use out of spec 8 byte status iu-s when they have no sense data,
switching to normal 16 byte status iu-s when they do have sense data.
3) They hang / crash when combined with some disks, e.g. a Crucial M500 ssd.
4) They hang / crash when stressed (through e.g. sg_reset --bus) with disks
with which then normally do work (once 1 & 2 are worked around).
Where as in BOT mode they appear to work fine, so the best way forward with
these devices is to just blacklist them for uas usage.
Unfortunately this is easier said then done. as older versions of the ASM1053
(which works fine) use the same usb-id as the ASM1051.
When connected over USB-3 the 2 can be told apart by the number of streams
they support. So this patch adds some less then pretty code to disable uas for
the ASM1051. When connected over USB-2, simply disable uas alltogether for
devices with the shared usb-id.

The uSCSI from Newer Technology is a SCSI-USB converter with USB ID 06ca:2003.
Like several other SCSI-USB products, it's a Shuttle Technology OEM device.
Without a suitable entry in unusual-devs.h, the converter can only access the
(single) device with SCSI ID 0. Copying the entry for device 04e6:0002 allows
it to work with devices with other SCSI IDs too.
There are currently six entries for Shuttle-developed SCSI-USB devices in
unusual-devs.h (grep for euscsi):
04e6:0002 Shuttle eUSCSI Bridge USB_SC_DEVICE, USB_PR_DEVICE
04e6:000b Shuttle eUSCSI Bridge USB_SC_SCSI, USB_PR_BULK

Some jmicron uas chipsets act up (they disconnect from the bus) when sending
more then 32 commands to them at once.
Rather then building an ever growing list with usb-id based quirks for
devices using this chipset, simply reduce the qdepth to 32 when connected
over usb-2. 32 should be plenty to keep things close to maximum
possible throughput on usb-2.

-This will result in lots of "virtual" scsi controllers confusing users
-If we get a scsi-bus-reset we will now need to do a usb-device-reset of all

The scsi error handling path re-uses previously queued up (and errored-out)
cmds. If such a re-used cmd had a data-phase then cmdinfo will have
data_in_urb / data_out_urb still set to the free-ed urbs from the errored-out
cmd, and they will get free-ed a second time when the error handling cmd
completes, corrupting the kernel heap.
Clearing cmdinfo on command queue-ing fixes this, and seems like a good idea
in general.

The scsi-host structure is refcounted, scsi_remove_host tears down the
scsi-host but does not decrement the refcount, so we need to call
scsi_put_host on disconnect to get the underlying memory to be freed.
After calling scsi_remove_host, the scsi-core may still hold a reference to
the scsi-host, iow we may still get called after uas_disconnect, but we
do our own life cycle management of uas_devinfo, freeing it on disconnect,
and thus may end up using devinfo after it has been freed. Switch to letting
scsi_host_alloc allocate and manage the memory for us.

Before this commit the uas driver would keep track of scsi commands which still
need to have some urbs submitted to the device, and complete this with an
ABORT result code on bus-reset or disconnect, but in flight scsi commands
which have all their urbs submitted, and thus are not part of the work list,
would never get their done callback called.
The problem is killed sense urbs don't have any tag info, so it is impossible
to tell which scsi cmd they belong to, so merely making sure all the urbs
have completed one way or the other is not enough.
This commit fixes this by changing the work list to an inflight list, which
keeps tracks of all inflight scsi cmnds, using the IS_IN_WORK_LIST flag to
determine if actual work needs to be done in uas_do_work(), and by moving
marking all inflight scsi commands as aborted and moving them to the dead list
on bus-reset or disconnect.
