commit 8010622c86ca5bb44bc98492f5968726fc7c7a21 upstream.
UAS does not share the pessimistic assumption storage is making that
devices cannot deal with WRITE_SAME. A few devices supported by UAS,
are reported to not deal well with WRITE_SAME. Those need a quirk.Add it to the device that needs it.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

Some USB mass-storage devices have bugs that cause them not to handle
the first READ(10) command they receive correctly. The Corsair
Padlock v2 returns completely bogus data for its first read (possibly
it returns the data in encrypted form even though the device is
supposed to be unlocked). The Feiya SD/SDHC card reader fails to
complete the first READ(10) command after it is plugged in or after a
new card is inserted, returning a status code that indicates it thinks
the command was invalid, which prevents the kernel from retrying the
read.Since the first read of a new device or a new medium is for the
partition sector, the kernel is unable to retrieve the device's
partition table. Users have to manually issue an "hdparm -z" or
"blockdev --rereadpt" command before they can access the device.This patch (as1470) works around the problem. It adds a new quirk
flag, US_FL_INVALID_READ10, indicating that the first READ(10) should
always be retried immediately, as should any failing READ(10) commands
(provided the preceding READ(10) command succeeded, to avoid getting
stuck in a loop). The patch also adds appropriate unusual_devs
entries containing the new flag.Signed-off-by: Alan Stern

This patch (as1311) fixes a problem in usb-storage: Some devices are
pretty broken when it comes to reporting sense data. The information
they send back indicates that they have more than 18 bytes of sense
data available, but when the system asks for more than 18 they fail or
hang. The symptom is that probing fails with multiple resets.The patch adds a new BAD_SENSE flag to indicate that usb-storage
should never ask for more than 18 bytes of sense data. The flag can
be set in an unusual_devs entry or via the "quirks=" module parameter,
and it is set automatically whenever a REQUEST SENSE command for more
than 18 bytes fails or times out.An unusual_devs entry is added for the Agfa photo frame, which uses a
Prolific chip having this bug.Signed-off-by: Alan Stern

This patch (as1206) is the first step in converting usb-storage's
subdrivers into separate modules. It makes the following large-scale
changes:Remove a bunch of unnecessary #ifdef's from usb_usual.h.
Not truly necessary, but it does clean things up.Move the USB device-ID table (which is duplicated between
libusual and usb-storage) into its own source file,
usual-tables.c, and arrange for this to be linked with
either libusual or usb-storage according to whether
USB_LIBUSUAL is configured.Add to usual-tables.c a new usb_usual_ignore_device()
function to detect whether a particular device needs to be
managed by a subdriver and not by the standard handlers
in usb-storage.Export a whole bunch of functions in usb-storage, renaming
some of them because their names don't already begin with
"usb_stor_". These functions will be needed by the new
subdriver modules.Split usb-storage's probe routine into two functions.
The subdrivers will call the probe1 routine, then fill in
their transport and protocol settings, and then call the
probe2 routine.Take the default cases and error checking out of
get_transport() and get_protocol(), which run during
probe1, and instead put a check for invalid transport
or protocol values into the probe2 function.Add a new probe routine to be used for standard devices,
i.e., those that don't need a subdriver. This new routine
checks whether the device should be ignored (because it
should be handled by ub or by a subdriver), and if not,
calls the probe1 and probe2 functions.Signed-off-by: Alan Stern

This patch (as1189b) adds some hacks to usb-storage for dealing with
the growing problems involving bad capacity values and last-sector
accesses:A new flag, US_FL_CAPACITY_OK, is created to indicate that
the device is known to report its capacity correctly. An
unusual_devs entry for Linux's own File-backed Storage Gadget
is added with this flag set, since g_file_storage always
reports the correct capacity and since the capacity need
not be even (it is determined by the size of the backing
file).An entry in unusual_devs.h which has only the CAPACITY_OK
flag set shouldn't prejudice libusual, since the device will
work perfectly well with either usb-storage or ub. So a
new macro, COMPLIANT_DEV, is added to let libusual know
about these entries.When a last-sector access succeeds and the total number of
sectors is odd (the unexpected case, in which guessing that
the number is even might cause trouble), a WARN is triggered.
The kerneloops.org project will collect these warnings,
allowing us to add CAPACITY_OK flags for the devices in
question before implementing the default-to-even heuristic.
If users want to prevent the stack dump produced by the WARN,
they can disable the hack by adding an unusual_devs entry
for their device with the CAPACITY_OK flag.When a last-sector access fails three times in a row and
neither the FIX_CAPACITY nor the CAPACITY_OK flag is set,
we assume the last-sector bug is present. We replace the
existing status and sense data with values that will cause
the SCSI core to fail the access immediately rather than
retry indefinitely. This should fix the difficulties
people have been having with Nokia phones.Signed-off-by: Alan Stern

Add the SANE SENSE flag to indicate that a device is capable of handling

USB-ATA bridges implementing SAT. A future patch will actually enable this
function for several devices.The logic behind this is that we can detect support for SANE_SENSE in a few ways:
1) ATA PASS THROUGH (12) or (16) execute successfully
2) SPC-3 or higher is in use
3) A previous CHECK CONDITION occurred with sense format 70-73 and had
a length greater than 18-bytes totalSigned-off-by: Ben Efros

- all application need to be patched
- A race is possible if there other accesses, because the emulation can
be split in 2 atacb scsi transactions. One for sending the command, one
for reading the register (if ck_cond is set).I have implemented the emulation in usb-storage with a special proto_handler,

that he wrote this driver without specs, however a vendor-supplied GPL

quite useful, as did the sddr09 driver which also has to deal with
low-level physical block layout on SmartMedia.The original patch has been reformed by me, as it clashed with the
