commit a0bb108112 upstream.
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.

commit f3f6faa9ed upstream.
This patch (as1312) fixes a minor bug in usb-storage. The
fill_inquiry() routine neglects to pre-load the inquiry data buffer
with spaces. As a result, if the vendor name is shorter than 8
characters or the product name is shorter than 16, the remainder will
be filled with garbage.
The patch also removes some unnecessary calls to strlen().

This patch (as1207) converts usb-storage's sddr09 subdriver into a
separate module.
An unexpected complication arises because of DPCM devices, in which
one LUN uses the sddr09 transport and one uses the standard CB
transport. Since these devices can be used even when
USB_STORAGE_SDDR09 isn't configured, their entries in unusual_devs.h
require special treatment. If SDDR09 isn't configured then the
entries remain in unusual_devs.h; if it is then the entries are
present in unusual_sddr09.h instead.

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.

This set of patches introduces calls to the following set of functions:
usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)

usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)
In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:
USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC

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.

Many newer Option mobile broadband devices initially provide a
usb-storage "driver CD" device that's pretty useless on Linux since
any software on it most likely wouldn't be compatible with your
kernel or distro anyway. Thus, by default just kill the driver
CD device by sending the SCSI 'rezero' command, but allow override
of the default behavior via usb-storage module parameter so users
can keep the ZeroCD device if they really want to. Inspired by
the Sierra TruInstall patch.

The DPCM subdriver is a little peculiar, in that it's meant to support
devices where LUN 0 is Compact Flash and uses the CB transport whereas
LUN 1 is SmartMedia and uses the SDDR09 transport. Thus DPCM isn't
really a transport in itself; it's more like a demultiplexer.
Much of the DPCM code is part of the SDDR09 subdriver already, and the
remaining part is fairly small. This patch (as1182) moves that extra
piece into sddr09.c, thereby eliminating dpcm.c. Also eliminated is
the Kconfig entry for DPCM support; it is now listed as part of the
SDDR09 entry.
In order to make sure that the semantics are the same as before, each
unusual_devs entry for DPCM is now present twice: once with DPCM
support if SDDR09 is configured (as before), and once with the
SINGLE_LUN flag and CB support otherwise.

This patch (as1163b) adds a "quirks=" module parameter to usb-storage.
This will allow people to make short-term changes to their
unusual_devs list without rebuilding the entire driver. Testing will
become much easier, and less-sophisticated users will be able to
access their buggy devices after a simple config-file change instead
of having to wait for a new kernel release.
The patch also adds a documentation entry for usb-storage's
"delay_use" parameter, which has been around for years but but was
never listed among the kernel parameters.
