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.

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

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

USB: skip autosuspended devices during system resume

System suspends and hibernation are supposed to be as transparent as
possible.  By this reasoning, if a USB device is already autosuspended
before the system sleep begins then it should remain autosuspended
after the system wakes up.

This patch (as1001) adds a skip_sys_resume flag to the usb_device
structure and uses it to avoid waking up devices which were suspended
when a system sleep began.

USB: allow usbstorage to have LUNS greater than 2Tb

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.

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.

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.

Alan Stern [Fri, 21 Sep 2007 20:57:54 +0000]
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.

However, the effect of the code was exactly opposite to the spec's

USB: usb-skeleton leaking locks on open

This weekend I was hacking around with a trivial USB driver for talking
to the boot load firmware of a USB Bit Whacker.  It's running the
MicroChip Pic18 boot loader firmware and I'm putting together a flash
program for writing new FW to the thing.

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.

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.

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.

This is appropriate, since devices exported to a virtualized guest or

though normal devices don't.

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.
