Hans de Goede a9c54caa45 uas: Disable uas on ASM1051 devices
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.

Mark a7e69ddb10 USB: storage: add quirk for Newer Technology uSCSI SCSI-USB converter
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
  04e6:000c  Shuttle eUSCSI Bridge    USB_SC_SCSI, USB_PR_BULK
  050d:0115  Belkin USB SCSI Adaptor  USB_SC_SCSI, USB_PR_BULK
  07af:0004  Microtech USB-SCSI-DB25  USB_SC_DEVICE, USB_PR_DEVICE
  07af:0005  Microtech USB-SCSI-HD50  USB_SC_DEVICE, USB_PR_DEVICE

lsusb -v output for the uSCSI lists
  bInterfaceSubClass      6 SCSI
  bInterfaceProtocol     80 Bulk (Zip)

This patch adds an entry for the uSCSI to unusual_devs.h.

Linus Torvalds 6b22df74f7 SCSI misc on 20140806
This patch set consists of the usual driver updates (ufs, storvsc, pm8001
 hpsa).  It also has removal of the user space target driver code (everyone is
 using LIO now), a partial PCI MSI-X update, more multi-queue updates,
 conversion to 64 bit LUNs (so we could theoretically cope with any LUN
 returned by a device) and placeholder support for the ZBC device type (Shingle
 drives), plus an assortment of minor updates and bug fixes.

Some jmicron uas chipsets act up (they disconnect from the bus) when sending

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.

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

After calling scsi_remove_host, the scsi-core may still hold a reference to

do our own life cycle management of uas_devinfo, freeing it on disconnect,

Hans de Goede 61c09ce510 uas: Properly complete inflight commands on bus-reset or disconnect
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.

I thought it would be a good idea to also test uas with usb-2, and it turns out
it was, as it did not work. The problem is that the uas driver was passing the
bEndpointAddress' direction bit to usb_rcvbulkpipe, the xhci code seems to not
care about this, but with the ehci code this causes usb_submit_urb failure.

With this fixed the uas code works nicely with an uas device plugged into

Alan Stern 823d12c95c usb-storage: enable multi-LUN scanning when needed
People sometimes create their own custom-configured kernels and forget
to enable CONFIG_SCSI_MULTI_LUN.  This causes problems when they plug
in a USB storage device (such as a card reader) with more than one
LUN.

Fortunately, we can tell fairly easily when a storage device claims to
have more than one LUN.  When that happens, this patch asks the SCSI
layer to probe all the LUNs automatically, regardless of the config
setting.

The patch also updates the Kconfig help text for usb-storage,
explaining that CONFIG_SCSI_MULTI_LUN may be necessary.

Tormod Volden 671b4b2ba9 usb-storage: CY7C68300A chips do not support Cypress ATACB
Many cards based on CY7C68300A/B/C use the USB ID 04b4:6830 but only the
B and C variants (EZ-USB AT2LP) support the ATA Command Block
functionality, according to the data sheets. The A variant (EZ-USB AT2)
locks up if ATACB is attempted, until a typical 30 seconds timeout runs
out and a USB reset is performed.

https://bugs.launchpad.net/bugs/428469

It seems that one way to spot a CY7C68300A (at least where the card
manufacturer left Cypress' EEPROM default vaules, against Cypress'
recommendations) is to look at the USB string descriptor indices.

A http://media.digikey.com/pdf/Data%20Sheets/Cypress%20PDFs/CY7C68300A.pdf
B http://www.farnell.com/datasheets/43456.pdf
C http://www.cypress.com/?rID=14189

Note that a CY7C68300B/C chip appears as CY7C68300A if it is running
in Backward Compatibility Mode, and if ATACB would be supported in this
case there is anyway no way to tell which chip it really is.

For 5 years my external USB drive has been locking up for half a minute
when plugged in and ata_id is run by udev, or anytime hdparm or similar
is run on it.

Finally looking at the /correct/ datasheet I think I found the reason. I
am aware the quirk in this patch is a bit hacky, but the hardware
manufacturers haven't made it easy for us.

o Add "struct us_data *" to usb_stor_dbg uses
o usb_stor_dbg now uses struct device */dev_vprint_emit
o Removed embedded function names
o Coalesce formats
o Remove trailing whitespace
o Remove useless OOM messages
o Remove useless function entry/exit logging
o Convert some US_DEBUGP uses to dev_info and dev_dbg

Object size is slightly reduced when debugging
is enabled, slightly increased with no debugging
because some initialization and removal messages
are now always emitted.

Reduce the size of the objects by consolidating
the duplicated USB_STORAGE into a single function.

Add function usb_stor_dbg to emit debugging messages.
Always validate the format and arguments.
Reduce the number of uses of CONFIG_USB_STORAGE_DEBUG.

Reduces size of objects ~7KB when CONFIG_USB_STORAGE_DEBUG
is set.

Bjørn Mork ab4b71644a USB: storage: fix Huawei mode switching regression
This reverts commit 200e0d99 ("USB: storage: optimize to match the
Huawei USB storage devices and support new switch command" and the
followup bugfix commit cd060956 ("USB: storage: properly handle
the endian issues of idProduct").

The commit effectively added a large number of Huawei devices to
the deprecated usb-storage mode switching logic.  Many of these
devices have been in use and supported by the userspace
usb_modeswitch utility for years.  Forcing the switching inside
the kernel causes a number of regressions as a result of ignoring
existing onfigurations, and also completely takes away the ability
to configure mode switching per device/system/user.

Known regressions caused by this:
 - Some of the devices support multiple modes, using different
  switching commands.  There are existing configurations taking
  advantage of this.

 - There is a real use case for disabling mode switching and
  instead mounting the exposed storage device. This becomes
  impossible with switching logic inside the usb-storage driver.

 - At least on device fail as a result of the usb-storage switching
  command, becoming completely unswitchable. This is possibly a
  firmware bug, but still a regression because the device work as
  expected using usb_modeswitch defaults.

In-kernel mode switching was deprecated years ago with the
development of the more user friendly userspace alternatives. The
existing list of devices in usb-storage was only kept to prevent
breaking already working systems.  The long term plan is to remove
the list, not to add to it. Ref:

Martin K. Petersen 5db44863b6 [SCSI] sd: Implement support for WRITE SAME
Implement support for WRITE SAME(10) and WRITE SAME(16) in the SCSI disk
driver.

 - We set the default maximum to 0xFFFF because there are several
   devices out there that only support two-byte block counts even with
   WRITE SAME(16). We only enable transfers bigger than 0xFFFF if the
   device explicitly reports MAXIMUM WRITE SAME LENGTH in the BLOCK
   LIMITS VPD.

 - max_write_same_blocks can be overriden per-device basis in sysfs.

 - The UNMAP discovery heuristics remain unchanged but the discard
   limits are tweaked to match the "real" WRITE SAME commands.

 - In the error handling logic we now distinguish between WRITE SAME
   with and without UNMAP set.

The discovery process heuristics are:

 - If the device reports a SCSI level of SPC-3 or greater we'll issue
   READ SUPPORTED OPERATION CODES to find out whether WRITE SAME(16) is
   supported. If that's the case we will use it.

 - If the device supports the block limits VPD and reports a MAXIMUM
   WRITE SAME LENGTH bigger than 0xFFFF we will use WRITE SAME(16).

 - Otherwise we will use WRITE SAME(10) unless the target LBA is beyond
   0xFFFFFFFF or the block count exceeds 0xFFFF.

 - no_write_same is set for ATA, FireWire and USB.

This reverts commit ceb3f91fd5.

IMO the real bug is assigning status urbs to scsi requests.  First there
is no such link in the non-stream case.  Also there isn't nessesarely a
scsi request in the first place, for example when submitting task
management requests.

This patch just papers over the real bug and introduces different status
urb handling in the stream/non-stream case for no good reason.

Gerd Hoffmann c621a81ede Revert "usb/uas: make sure data urb is gone if we receive status before that"
This reverts commit e4d8318a85.

This patch makes uas.c call usb_unlink_urb on data urbs.  The data urbs
get freed in the completion callback.  This is illegal according to the
usb_unlink_urb documentation.

This patch also makes the code expect the data completion callback
being called before the status completion callback.  This isn't
guaranteed to be the case, even though the actual data transfer should
be finished by the time the status is received.

Background:  The ehci irq handler for example only know that there are
finished transfers, it then has go check the QHs & TDs to see which
transfers did actually finish.  It has no way to figure in which order
the transfers did complete.  The xhci driver can call the callbacks in
completion order thanks to the event queue.  This does nicely explain
why the driver is solid on a (usb2) xhci port whereas it goes crazy on
ehci in my testing.

Alan Stern 6a0bdffa00 SCSI & usb-storage: add try_rc_10_first flag
Several bug reports have been received recently for USB mass-storage
devices that don't handle READ CAPACITY(16) commands properly.  They
report bogus sizes, in some cases becoming unusable as a result.

The bugs were triggered by commit
09b6b51b0b (SCSI & usb-storage: add
flags for VPD pages and REPORT LUNS), which caused usb-storage to stop
overriding the SCSI level reported by devices.  By default, the sd
driver will try READ CAPACITY(16) first for any device whose level is
above SCSI_SPC_2.

It seems likely that any device large enough to require the use of
READ CAPACITY(16) (i.e., 2 TB or more) would be able to handle READ
CAPACITY(10) commands properly.  Indeed, I don't know of any devices
that don't handle READ CAPACITY(10) properly.

Therefore this patch (as1559) adds a new flag telling the sd driver
to try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag
for every USB mass-storage device.  If a device really is larger than
2 TB, sd will fall back to READ CAPACITY(16) just as it used to.

This fixes Bugzilla #43391.
