442258e2ff USB: use IRQF_DISABLED for HCD interrupt handlers
Host controller IRQs are supposed to be serviced with interrupts
disabled.  This patch (as1026) adds an IRQF_DISABLED flag to all the
controller drivers that lack it.  It also replaces the
spin_lock_irqsave() and spin_unlock_irqrestore() calls in uhci_irq()
with simple spin_lock() and spin_unlock().

This fixes Bugzilla #9335.

d48bd977e0 USB: fix locking loop by avoiding flush_scheduled_work
This patch (as1027) replaces a call to flush_scheduled_work() -- a
dangerous routine to invoke, especially while holding any sort of lock
-- with calls to cancel_work_sync() and cancel_delayed_work_sync().

This fixes Bugzilla #9532.

8be27c2de6 USB: cp2101: new device id
This adds a device ID for the Aerocomm Radio Modem, which uses the
cp2102.  I'm sure changing num_bulk_in/num_bulk_out to NUM_DONT_CARE
is the wrong fix, but this is the only device I have with a cp2102,
so I have no idea what a good global value would be, if there is one.
Zero didn't work with this device.

33abc04f04 usb-storage: Fix devices that cannot handle 32k transfers
When a device cannot handle the smallest previously limited transfer
size (64 blocks) without stalling, limit the device to the amount of
packets that fit in a platform native page.

The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever
used on a platform that has larger than 8K pages, you lose unless you
can convince the device firmware folks to fix the issue.

Revert 7eea436433.

Lucy said:

  This patch will work with the 19HS but WILL BREAK all other Keyspan
  adapters.  It will take me a few days to get to looking at a correct fix but
  that keyspan_send_setup(port, 1) (and the '1' is the important part) must
  happen once when the port is first opened.  The cflag can just be set to
  whatever the normal default is for your serial environment.

So revert this again pending the proper fix.

4a9bee8256 USB: uevent environment key fix
This patch (as1010) was written by both Kay Sievers and me.  It solves
the problem of duplicated keys in USB uevent structures by refactoring
the uevent subroutines, taking advantage of the way the hotplug core
calls uevent handlers for the device's bus and for the device's type.
Keys needed for both USB-device and USB-interface events are added in
usb_uevent(), which is the bus handler.  Keys appropriate only for
USB-device or USB-interface events are added in usb_dev_uevent() or
usb_if_uevent() respectively, the type handlers.

In addition, unnecessary tests for NULL pointers are removed as are
duplicated debugging log statements.

f08812d5eb USB: FIx locks and urb->status in adutux (updated)
Two main issues fixed here are:
 - An improper use of in-struct lock to protect an open count
 - Use of urb status for -EINPROGRESS

Also, along the way:
 - Change usb_unlink_urb to usb_kill_urb. Apparently there's no need
   to use usb_unlink_urb whatsoever in this driver, and the old use of
   usb_kill_urb was outright racy (it unlinked and immediately freed).
 - Fix indentation in adu_write. Looks like it was damaged by a script.
 - Vitaly wants -EBUSY on multiply opens.
 - bInterval was taken from a wrong endpoint.

439a903a96 USB: fix interface sysfs file-creation bug
This patch (as1005) fixes a rather subtle problem.  When
usb_set_configuration() registers the interfaces and their files in
sysfs, it doesn't expect those files to exist already.  But when an
interface is registered, its driver may call usb_set_interface() and
thereby cause the sysfs files to be created.  The result is an error
when usb_set_configuration() goes on to create those same files again.

The (not-so-great) solution is to have usb_set_configuration() remove
any existing files before creating them.

3794ade5b2 USB: isd200: sort out USB/IDE dependancy mess
The ISD200 driver imports a single trivial routine from the IDE layer and
in doing so creates a mess of dependancies that drag in the entire old
IDE layer. Even more sad - it does this for a routine which is usually
(little endian) a null function!

- Copy the function into ISD200
- Rename it so it doesn't clash with the ide header prototype
- Remove all the depend constraints

URBs in which the flag isn't set will be scheduled for the first slot
following the last URB, even if it has expired.

  45711f1af6 ("[SG] Update drivers to use sg helpers")
  fa05f1286b ("Update net/ to use sg helpers")

converted many files to use the scatter gather helpers without ensuring
that the necessary headerfile <linux/scatterlist> is included.  This
happened to work for ia64, powerpc, sparc64 and x86 because they
happened to drag in that file via their <asm/dma-mapping.h>.

On most of the others this probably broke.

Instead of increasing the header file spider web I choose to include
<linux/scatterlist.h> directly into the affectes files.

ba25f9dcc4 Use helpers to obtain task pid in printks
The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.

The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

e400b6ec4e vt/vgacon: Check if screen resize request comes from userspace
Various console drivers are able to resize the screen via the con_resize()
hook.  This hook is also visible in userspace via the TIOCWINSZ, VT_RESIZE and
VT_RESIZEX ioctl's.  One particular utility, SVGATextMode, expects that
con_resize() of the VGA console will always return success even if the
resulting screen is not compatible with the hardware.  However, this
particular behavior of the VGA console, as reported in Kernel Bugzilla Bug
7513, can cause undefined behavior if the user starts with a console size
larger than 80x25.

To work around this problem, add an extra parameter to con_resize().  This
parameter is ignored by drivers except for vgacon.  If this parameter is
non-zero, then the resize request came from a VT_RESIZE or VT_RESIZEX ioctl
and vgacon will always return success.  If this parameter is zero, vgacon will
return -EINVAL if the requested size is not compatible with the hardware.  The
latter is the more correct behavior.

With this change, SVGATextMode should still work correctly while in-kernel and
stty resize calls can expect correct behavior from vgacon.

d1aa3e6aa8 USB: fix race in autosuspend reschedule
This patch (as1002) fixes a small race which can occur when a driver
expects usbcore to reschedule an autosuspend request.  If the request
arrives too late, it won't be rescheduled.  The patch adds an extra
argument to autosuspend_check(), indicating that a reschedule is
needed no matter how much time has elapsed.

It also tries to avoid letting asynchronous changes to the value of
jiffies cause a delay to become negative, by caching a local copy of
the current time.

063a2da8f0 USB: serial core should respect driver requirements
This patch (as997) fixes a bug in the USB serial core.  The core needs
to pay attention to drivers' requirements regarding the number and
type of endpoints a device has.

At the same time, the patch changes the NUM_DONT_CARE constant (which
is stored in a single-byte field) from -1 to a safer, unsigned value.
It also improves the kerneldoc for several fields in the
usb_serial_driver structure.

Finally, the patch replaces a list_for_each() with list_for_each_entry().

Attached is a very small patch (several comment lines) and a one-line
coded change) that allows for USB storage devices that are larger than
2TB.

At the company where I work we need such support, and one of my
co-workers, Jane Liu, pointed out that SCSI low-layer drivers need to
specify what size CDBs they accept. After looking through the code it
became obvious that the current USB Storage code accepted the default of
12-byte CDBs, so I changed it to accept 16-byte CDBs. This allows our
device to work.

4f45426cfd USB: add runtime frame_no quirk for big-endian OHCI
Add OHCI big endian frame_no quirk.  The frame_no value stored in the
HCCA is a 16 bit field at a specific offset, but since not all CPUs can
do 16-bit memory accesses it's used as a 32 bit field.  And that's why
big-endian OHCI must shift 16 bits ... unless the spec is not followed.

Currently there's one MPC52xx platform that doesn't need the shift. This
patch adds a new "big endian frame_no" quirk to control that at runtime.

5395353e0c usb-gadget-ether: prevent oops caused by error interrupt race
Fix a longstanding race in the Ethernet gadget driver, which can cause an
oops on device disconnect.  The fix is just to make the TX path check
whether its freelist is empty.  That check is otherwise not necessary,
since the queue is always stopped when that list empties (and restarted
when request completion puts an entry back on that freelist).

The race window starts when the network code decides to transmit a packet,
and ends when hard_start_xmit() grabs the freelist lock.  When disconnect()
is called inside that window, it shuts down the TX queue and breaks the
otherwise-solid assumption that packets are never sent through a TX queue
that's stopped.

a691efa988 USB: remove USB_QUIRK_NO_AUTOSUSPEND
This patch (as995) cleans up the remains of the former NO_AUTOSUSPEND
quirk.  Since autosuspend is disabled by default, we will let
userspace worry about which devices can safely be suspended.  Thus the
lengthy series of quirk entries is no longer needed, and neither is
the quirk ID.  I suppose someone might eventually run across a hub
that can't be suspended; let's ignore the possibility for now.

The patch also cleans up the hasty way in which autosuspend gets
disabled.  Setting udev->autosuspend_delay to -1 wasn't quite right,
because the value is always supposed to be a multiple of HZ.  It's
better to leave the delay value alone and set autosuspend_disabled,
which is what the quirk routine used to do.

Anyway in my use of the usb-skeleton.c as my starting point I discovered
my test program was getting hung up after attempting to write a buffer.
The application and driver where hung in a way that required me to
reboot to get it to clean up so I could try again.

It turned out the code path through skel_open can grap the driver's
io_mutex lock and forget to release it.

The following patch fixes the problem for me.

6840d2555a USB: flush outstanding URBs when suspending
This patch (as989) makes usbcore flush all outstanding URBs for each
device as the device is suspended.  This will be true even when
CONFIG_USB_SUSPEND is not enabled.

In addition, an extra can_submit flag is added to the usb_device
structure.  That flag will be turned off whenever a suspend request
has been received for the device, even if the device isn't actually
suspended because CONFIG_USB_SUSPEND isn't set.

It's no longer necessary to check for the device state being equal to
USB_STATE_SUSPENDED during URB submission; that check can be replaced
by a check of the can_submit flag.  This also permits us to remove
some questionable references to the deprecated power.power_state field.

95cf82f99c USB: break apart flush_endpoint and disable_endpoint
This patch (as988) breaks usb_hcd_endpoint_disable() apart into two
routines.  The first, usb_hcd_flush_endpoint() does the -ESHUTDOWN
unlinking of all URBs in the endpoint's queue and waits for them to
complete.  The second, usb_hcd_disable_endpoint() -- renamed for
better grammatical style -- merely calls the HCD's endpoint_disable
method.  The changeover is easy because the routine currently has only
one caller.

This separation of function will be exploited in the following patch:
When a device is suspended, the core will be able to cancel all
outstanding URBs for that device while leaving the HCD's
endpoint-related data structures intact for later.

As an added benefit, HCDs no longer need to check for existing URBs in
their endpoint_disable methods.  It is now guaranteed that there will
be none.

5ad4f71e2f USB: move decision to ignore FREEZE events
This patch (as987) changes the way FREEZE and PRETHAW suspend events
are handled in usbcore.  The decision about whether or not to ignore
them for non-root devices is pushed down into the USB-device driver,
instead of being made in the core code.

This is appropriate, since devices exported to a virtualized guest or
over a network may indeed need to handle these types of suspend, even
though normal devices don't.

ce0d9325b1 usb-serial: show port number in sysfs
Some usb-serial devices (e.g. certain Edgeport models) have more than
one serial port on the same USB device/interface.

Currently the only way to distinguish these ports in userspace is by
their minor device number: the driver makes them consecutive and in
stable order.

However, for the purpose of stable naming with udev this is
insufficient: when udev handles the ADD event for one of the ports it
doesn't know what minor number the other one has.

To make stable naming easier, export the port number via sysfs.

42cb967fd0 usblp: Fix a double kfree
If submit fails, slab hits a BUG() because of a double kfree.
The today's lesson is, you cannot just slap USB_FREE_BUFFER on code
without adjusting the error paths.

The patch is made bigger by opportunistic refactoring.

Add a mutex to protect the ->statusbuf. Not really an issue, because CUPS

This patch (as957) makes some minor cleanups to the g_file_storage
driver:

	Update the copyright date and version string;

	Uniformize the logging macros for the gadget and the LUNs;

	Remove "inline" markers -- nowadays we rely on the compiler
	to decide which routines are best inlined;

	Use the print_hex_dump() library routines;

	Remove some unnecessary assignments within conditionals
	and fix some close-brace indenting levels;

	Fix some column-80 violations.

d74d4a69dc USB: don't touch sysfs stuff when altsetting is unchanged
This patch (as955) prevents the interface-related sysfs files and
endpoint pseudo-devices from being deleted and recreated when a call
to usb_set_interface() specifies the current altsetting.  Since the
altsetting doesn't get changed, there's no need to do anything.

Furthermore, avoiding changes to the endpoint devices will be
necessary in the future.  This code is called from usb_reset_device(),
which gets invoked for reset-resume processing, but upcoming changes
to the PM and driver cores will make it impossible to register devices
while a suspend/resume transition is in progress.  Since we don't need
to re-register those endpoint devices anyhow, it's best to skip the
whole thing.

e9df41c5c5 USB: make HCDs responsible for managing endpoint queues
This patch (as954) implements a suggestion of David Brownell's.  Now
the host controller drivers are responsible for linking and unlinking
URBs to/from their endpoint queues.  This eliminates the possiblity of
strange situations where usbcore thinks an URB is linked but the HCD
thinks it isn't.  It also means HCDs no longer have to check for URBs
being dequeued before they were fully enqueued.

In addition to the core changes, this requires changing every host
controller driver and the root-hub URB handler.  For the most part the
required changes are fairly small; drivers have to call
usb_hcd_link_urb_to_ep() in their urb_enqueue method,
usb_hcd_check_unlink_urb() in their urb_dequeue method, and
usb_hcd_unlink_urb_from_ep() before giving URBs back.  A few HCDs make
matters more complicated by the way they split up the flow of control.

In addition some method interfaces get changed.  The endpoint argument
for urb_enqueue is now redundant so it is removed.  The unlink status
is required by usb_hcd_check_unlink_urb(), so it has been added to
urb_dequeue.

93993a0a3e usb: introduce usb_authorize/deauthorize()
These USB API functions will do the full authorization/deauthorization
to be used for a device. When authorized we effectively allow a
configuration to be set. Reverse that when deauthorized.

Effectively this means that we have to clean all the configuration
descriptors on deauthorize and reload them when we authorized. We could
do without throwing them out for wired devices, but for wireless, we can
read them only after authenticating, and thus, when authorizing an
authenticated device we would need to read them. So to simplify, always
release them on deauthorize(), re-read them on authorize().

Also fix leak reported by Ragner Magalhaes; in usb_deauthorize_device(),
bNumConfigurations was being set to zero before the for loop, and thus
the different raw descriptors where never being freed.

d9d16e8a92 usb: split usb_new_device for clarity and refactoring
This patch takes hub.c:usb_new_device() and splits it in three parts:

- The actual actions of adding a new device (quirk detection,
  announcement and autoresume tracking)

- Actual discovery and probing of the configuration and interfaces
  (split into __usb_configure_device())

- Configuration of the On-the-go parameters (split into
  __usb_configure_device_otg()).

The fundamental reasons for doing this split are clarity (smaller
functions are easier to maintain) and to allow part of the code to be
reused when authorizing devices to connect.

When a device is authorized connection, we need to run through the
hoops we didn't run when it was connected but not authorized, which is
basically parsing the configurations and probing
them. usb_configure_device() will do that for us.
