HID: hidraw: fix window in hidraw_release

2011-01-07T22:43:13+00:00

commit cb174681a9ececa6702f114b85bdf82144b6a5af upstream.

[ Backport to .32.y by Antonio Ospite  ]

There is a window between hidraw_table check and its dereference.
In that window, the device may be unplugged and removed form the
system and we will then dereference NULL.

Lock that place properly so that either we get NULL and jump out or we
can work with real pointer.

HID: hidraw, fix a NULL pointer dereference in hidraw_write

2010-12-09T21:27:05+00:00

commit e42dee9a99a3ecd32b5c027e8f7411fb5bc11eb6 upstream.

BUG: unable to handle kernel NULL pointer dereference at 0000000000000028
IP: [] hidraw_write+0x3b/0x116 [hid]
[...]

This is reproducible by disconnecting the device while userspace writes
to dev node in a loop and doesn't check return values in order to exit
the loop.

HID: fix suspend crash by moving initializations earlier

2010-09-20T20:17:51+00:00

commit fde4e2f73208b8f34f123791e39c0cb6bc74b32a upstream.

Although the usbhid driver allocates its usbhid structure in the probe
routine, several critical fields in that structure don't get
initialized until usbhid_start().  However if report descriptor
parsing fails then usbhid_start() is never called.  This leads to
problems during system suspend -- the system will freeze.

This patch (as1378) fixes the bug by moving the initialization
statements up into usbhid_probe().

HID: usbhid: initialize interface pointers early enough

2010-09-20T20:17:51+00:00

commit 57ab12e418ec4fe24c11788bb1bbdabb29d05679 upstream.

Move the initialization of USB interface pointers from _start()
over to _probe() callback, which is where it belongs.

This fixes case where interface is NULL when parsing of report
descriptor fails.

HID: Add the GYR4101US USB ID to hid-gyration

2010-07-05T18:10:33+00:00

commit c2fd1a4ebf9127c280d227acb635eb1df213439c upstream.

This change adds in the USB product ID for the Gyration
GYR4101US USB media center remote control.  This remote
is similar enough to the other two devices that this driver
can be used without any other changes to get full support
for the remote.

HID: usbhid: introduce timeout for stuck ctrl/out URBs

2010-03-15T15:49:37+00:00

commit 858155fbcc0cd713f6382c527bb1c3abc0ed6d00 upstream.

Some devices do not react to a control request (seen on APC UPS's) resulting in
a slow stream of messages, "generic-usb ... control queue full".  Therefore
request needs a timeout.

HID: add multi-input quirk for NextWindow Touchscreen.

2010-03-15T15:49:37+00:00

commit 9db630b48a99adb4156e205b812fba8959644280 upstream.

These touchscreens are mounted onto HP TouchSmart and the Dell Studio One
19. Without a quirk they report a wrong button set and the x/y coordinates
through ABS_Z/ABS_RX, confusing the higher levels (most notably X.Org's
evdev driver).

Device id 0x003 covers models 1900, 2150, and 2700 [1] though testing could
only be performed on a model 1900.
