Input: iforce - validate number of endpoints before using them

2017-03-30T07:35:14+00:00

commit 59cf8bed44a79ec42303151dd014fdb6434254bb upstream.

Make sure to check the number of endpoints to avoid dereferencing a
NULL-pointer or accessing memory that lie beyond the end of the endpoint
array should a malicious device lack the expected endpoints.

Input: xpad - use correct product id for x360w controllers

2017-01-19T19:17:18+00:00

commit b6fc513da50c5dbc457a8ad6b58b046a6a68fd9d upstream.

currently the controllers get the same product id as the wireless
receiver. However the controllers actually have their own product id.

The patch makes the driver expose the same product id as the windows
driver.

This improves compatibility when running applications with WINE.

Input: xpad - correctly handle concurrent LED and FF requests

2016-09-15T06:27:46+00:00

[ Upstream commit 7fc595f4c02636eadaeeecfe7bbc45b57c173004 ]

Track the status of the irq_out URB to prevent submission iof new requests
while current one is active. Failure to do so results in the "URB submitted
while active" warning/stack trace.

Store pending brightness and FF effect in the driver structure and replace
it with the latest requests until the device is ready to process next
request. Alternate serving LED vs FF requests to make sure one does not
starve another. See [1] for discussion. Inspired by patch of Sarah Bessmer
[2].

Input: xpad - fix oops when attaching an unknown Xbox One gamepad

2016-08-10T09:49:26+00:00

commit c7f1429389ec1aa25e042bb13451385fbb596f8c upstream.

Xbox One controllers have multiple interfaces which all have the
same class, subclass, and protocol. One of the these interfaces
has only a single endpoint. When Xpad attempts to bind to this
interface, it causes an oops when trying initialize the output URB
by trying to access the second endpoint's descriptor.

This situation was avoided for known Xbox One devices by checking
the XTYPE constant associated with the VID and PID tuple. However,
this breaks when new or previously unknown Xbox One controllers
are attached to the system.

This change addresses the problem by deriving the XTYPE for Xbox
One controllers based on the interface protocol before checking
the interface number.
