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.

Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.
The patch below presents a simple SCSI host lock push-down as an
equivalent transformation. No locking or other behavior should change
with this patch. All existing bugs and locking orders are preserved.
Additionally, add one parameter to queuecommand,
struct Scsi_Host *
and remove one parameter from queuecommand,
void (*done)(struct scsi_cmnd *)
Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.
Minimal code disturbance was attempted with this change. Most drivers
needed only two one-line modifications for their host lock push-down.

This patch (as1400) adds runtime-PM support to usb-storage. It
utilizes the SCSI layer's runtime-PM implementation, so its scope is
limited. Currently the only effect is that disk-like devices (such as
card readers or flash drives) will be autosuspended if they aren't
mounted and their device files aren't open. This would apply, for
example, to card readers that don't contain a memory card.
Unfortunately this won't interact very well with the removable-media
polling normally carried out by hal or DeviceKit. Maybe those
programs can be changed to use a longer polling interval, or maybe the
default autosuspend time for usb-storage should be set to something
below 1 second.

While at it, as Alan Stern points out, the initializers for

only matters for isochronous urbs, so they don't need to be set here.

This patch (as1350) removes all usages of coherent buffers for USB
control-request setup-packet buffers. There's no good reason to
reserve coherent memory for these things; control requests are hardly
ever used in large quantity (the major exception is firmware
transfers, and they aren't time-critical). Furthermore, only seven
drivers used it. We might as well always use streaming DMA mappings
for setup-packet buffers, and remove some extra complexity from
usbcore.
The DMA-mapping portion of hcd.c is currently in flux. A separate
patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP
after everything else settles down. The removal should go smoothly,
as by then nobody will be using it.

The compiler throws the following warning when compiling for a PowerPC 64
bit machine:
drivers/usb/storage/isd200.c:580: warning: the frame size of 2208 bytes is larger than 2048 bytes
There is a struct scsi_device which is placed on the stack and is
largely responsible for such wastage. The struct is just a dummy struct
filled with NULLs and set as the scsi_cmnd->device to make the
usb_stor_Bulk_transport function happy.
This patch makes the struct static, so that it is never placed onto the
stack and silences the compiler warning.

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

This patch (as1347) makes some adjustments to the way usb-storage
handles the request-queue parameters.
USB host controllers are able to handle arbitrarily long
scatter-gather lists, since they are limited only by main memory and
not by the controller hardware. Hence the sg_tablesize field in the
host template can be increased to the maximum value.
Drivers like usb-storage aren't supposed to touch the queue's
max_sectors parameter; instead they are supposed to use the
max_hw_sectors value. Accordingly, the patch replaces calls of
queue_max_sectors() with calls of queue_max_hw_sectors(). Oddly
enough, the blk_queue_max_sectors() routine is nevertheless still
appropriate.
The existing code imposes a limit of SCSI_DEFAULT_MAX_SECTORS (1024)
on the values accepted by the max_sectors attribute file. There's no
reason not to accept larger values, so the limit is removed. (It
would be nice to change the file's name to max_hw_sectors, but the old
name is already a well-established API.)

The five-second delay can be rather annoying, and makes the system
appear much less responsive when you connect a USB drive.
It's also not entirely clear that it is needed - the settling delay has
at least historically been an issue on some Apple iPods, for example,
and some devices have been reported to need even more than the old 5s
delay.
But before we penalize them all, let's see how bad it really is. Some
of the reasons for long delays seem to be actual historical kernel bugs
that should probably never have been papered over with a delay in the
first place (there's a Ubuntu bug report for 2.6.20 about a NULL pointer
dereference unless 'delay_use' is 8 or more, for example).
It also looks like some distros have already shipped with delay_use=0,
so the five second default may well be totally historical.
In other words: "Let's see if anybody screams".

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

usb-storage: Workaround devices with bogus sense size
Some devices, such as Huawei E169, advertise more than the standard
amount of sense data, causing us to set US_FL_SANE_SENSE, assuming
they support it. However, they subsequently fail the request sense
with that size.
This works around it generically. When a sense request fails due to
a device returning an error, US_FL_SANE_SENSE was set, and that sense
request used a larger sense size, we retry with a smaller size before
giving up.

This patch (as1294) fixes a problem that has plagued users for several
kernel releases. Some USB mass-storage devices don't return any sense
data when they encounter certain kinds of errors. The SCSI layer
interprets this to mean that the operation should be retried, and the
same thing happens -- over and over again with no limit. In some
circumstances (such as when a bus reset occurs) that is the right
thing to do, but not here.
The patch checks for this condition (a transport failure with no sense
data) and changes the result code to DID_ERROR and the sense code to
Hardware Error. This does get only a limited number of retries, and
so the command will fail relatively quickly instead of getting stuck
in an infinite loop.
This fixes a large part of Bugzilla #14118.

Wireless USB endpoint state has a sequence number and a current
window and not just a single toggle bit. So allow HCDs to provide a
endpoint_reset method and call this or clear the software toggles as
required (after a clear halt, set configuration etc.).
usb_settoggle() and friends are then HCD internal and are moved into
core/hcd.h and all device drivers call usb_reset_endpoint() instead.
If the device endpoint state has been reset (with a clear halt) but
the host endpoint state has not then subsequent data transfers will
not complete. The device will only work again after it is reset or

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 patch makes it set the ->cmnd buffer after scsi_eh_prep_cmnd call.
The problem and a fix was reported by Matthieu CASTET <castet.matthieu@free.fr>
It also removes all the hackery fiddling of scsi_cmnd and scsi_eh_save by
requesting from scsi_eh_prep_cmnd to prepare a read into ->sense_buffer,
which is much more suitable a buffer for HW transfers, then after the command

of sense_buffer.

This patch (as1203) increases the max_sector limit for USB tape
drives. By default usb-storage sets max_sectors to 240 (i.e., 120 KB)

an entire large block in a single command, such tapes can't be used.

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.

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 (as1175) makes usb-storage set a SCSI device's
request-queue bounce limit such that all buffers will be located in
addressable memory (i.e., not in high memory) if the host controller's
dma_mask is NULL. This is necessary when the host controller doesn't
support DMA: If a buffer is in high memory then the both the virtual

preventing the HCD from accessing the buffer's data.

The new routine will not return immediately if it is called while the
