      HID: support primax keyboards violating USB HID spec · f6a04605
      由 Terry Lambert 提交于 
      Primax keyboards with the issue this driver addresses report modifier
keys as in band key events instead of as out of band modifier bits,
resulting in the modifier keys generating key up events immediately
before the keys they are intended to modify.  This driver rewrites
the raw report data from such keyboards into USB HID 1.11 compliant
report data.  It only matches the USB vendor and product IDs for the
keyboard it has been tested on. Since there are several keyboards,
notably a number of laptops and folding USB keyboards known to have
similar unresolved problem reports, the list is expected to grow.

      HID: Add full support for Logitech Unifying receivers · 534a7b8e
      由 Nestor Lopez Casado 提交于 
      With this driver, all the devices paired to a single Unifying
receiver are exposed to user processes in separated /input/dev
nodes.

Keyboards with different layouts can be treated differently,
Multiplayer games on single PC (like home theater PC) can
differentiate input coming from different kbds paired to the
same receiver.

Up to now, when Logitech Unifying receivers are connected to a
Linux based system, a single keyboard and a single mouse are
presented to the HID Layer, even if the Unifying receiver can
pair up to six compatible devices. The Unifying receiver by default
multiplexes all incoming events (from multiple keyboards/mice)
into these two.

      HID: Fix race condition between driver core and ll-driver · 4ea54542
      由 David Herrmann 提交于 
      HID low level drivers register new devices with the HID core which then
adds the devices to the HID bus. The HID bus normally immediately probes
an appropriate driver which then handles HID input for this device.
The ll driver now uses the hid_input_report() function to report input
events for a specific device. However, if the HID bus unloads the driver
at the same time (for instance via a call to
 /sys/bus/hid/devices/<dev>/unbind) then the hdev->driver pointer may be
used by hid_input_report() and hid_device_remove() at the same time
which may cause hdev->driver to point to invalid memory.

This fix adds a semaphore to every hid device which protects
hdev->driver from asynchronous access. This semaphore is locked during
driver *_probe and *_remove and also inside hid_input_report(). The
*_probe and *_remove functions may sleep so the semaphore is good here,
however, hid_input_report() is in atomic context and hence only uses
down_trylock(). If it cannot acquire the lock it simply drops the input
package.

The low-level drivers report input events synchronously so
hid_input_report() should never be entered twice at the same time on the
same device. Hence, the lock should always be available. But if the
driver is currently probed/removed then the lock is not available and
dropping the package should be safe because this is what would have
happened if the package arrived some milliseconds earlier/later.

This also fixes another race condition while probing drivers:
First the *_probe function of the driver is called and only if that
succeeds, the related input device of hidinput is registered. If the low
level driver reports input events after the *_probe function returned
but before the input device is registered, then a NULL pointer
dereference will occur. (Equivalently on driver remove function).
This is not possible anymore, since the semaphore lock drops all
incoming packages until the driver/device is fully initialized.

      HID: Add driver to fix Speedlink VAD Cezanne support · 74bc6953
      由 Stefan Kriwanek 提交于 
      Speedlink VAD Cezanne have a hardware bug that makes the cursor "jump" from one
place to another every now and then. The issue are relative motion events
erroneously reported by the device, each having a distance value of +256. This
256 can in fact never occur due to real motion, therefore those events can
safely be ignored.  The driver also drops useless EV_REL events with a value of
0, that the device sends every time it sends an "real" EV_REL or EV_KEY event.
