usb-storage: prepare for subdriver separation
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.

|
|
|
* devices. Clearly, the designers had SCSI and ATAPI commands in

|
|
|
|
* similar to commands in the SCSI-II and ATAPI specifications.

|
|
|
*
|
|
|
|
* It is important to note that in a number of cases this class
|
|
|
|
* exhibits class-specific exemptions from the USB specification.
|
|
|
|
* Notably the usage of NAK, STALL and ACK differs from the norm, in
|
|
|
|
* that they are used to communicate wait, failed and OK on commands.
|
|
|
|
*
|
|
|
|
* Also, for certain devices, the interrupt endpoint is used to convey
|
|
|
|
* status of a command.

USB: storage: add last-sector hacks
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.

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

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.

usb-storage: prepare for subdriver separation
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.

usb-storage: prepare for subdriver separation
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.

usb-storage: prepare for subdriver separation
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.

usb-storage: prepare for subdriver separation
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.

usb-storage: prepare for subdriver separation
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.

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.
