Input: iforce - validate number of endpoints before using them

2017-07-04T09:51:20+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 - x360w: report dpad as buttons and axes

2017-04-11T08:57:31+00:00

as discussed here[0], x360w is the only pad that maps dpad_to_button. This is bad for downstream developers as they have to differ between x360 and x360w which is not intuitive. This patch implements the suggested solution of exposing the dpad both as axes and as buttons. This retains backward compatibility with software already dealing with the difference while makes new software work as expected across x360/ x360w pads.

Input: xpad - factor out URB submission in xpad_play_effect

2017-04-11T08:57:30+00:00

Move submission logic to a single point at the end of the function. This makes it easy to add locking/ queuing code later on. Signed-off-by: Pavel Rojtberg Signed-off-by: Dmitry Torokhov Signed-off-by: Tim Clark

Input: xpad - remove needless bulk out URB used for LED setup

2017-04-11T08:57:30+00:00

This code was probably wrong ever since and is redundant with xpad_send_led_command. Both try to send a similar command to the xbox360 controller. However xpad_send_led_command correctly uses the pad_nr instead of bInterfaceNumber to select the led and re-uses the irq_out URB instead of creating a new one. Note that this change only affects the two supported wireless controllers. Tested using the xbox360 wireless controller (PC).

Input: xpad - use ida() for finding the pad_nr

2017-04-11T08:57:30+00:00

The pad_nr corresponds to the lit up LED on the controller. Therefore there should be no gaps when enumerating. Currently a LED is only re-assigned after a controller is re-connected 4 times. This patch uses ida to track connected pads - this way we can re-assign freed up pad number immediately. Consider the following case: 1. pad A is connected and gets pad_nr = 0 2. pad B is connected and gets pad_nr = 1 3. pad A is disconnected 4. pad A is connected again using ida_simple_get() controller A now correctly gets pad_nr = 0 again.

Input: xpad - clarify LED enumeration

2017-04-11T08:57:30+00:00

Rename led_no -> pad_nr: the number stored there is not the LED number - it gets translated later on to a LED number in xpad_identify_controller; Signed-off-by: Pavel Rojtberg Signed-off-by: Dmitry Torokhov Signed-off-by: Tim Clark

Input: xpad - fix Razer Atrox Arcade Stick button mapping

2017-04-11T08:57:29+00:00

The "Razer Atrox Arcade Stick" features 10 buttons, and two of them (LT/RT) don't work properly. Change its definition in xpad_device[] (mapping field) to fix. Signed-off-by: Dario Scarpa Signed-off-by: Pavel Rojtberg Signed-off-by: Dmitry Torokhov Signed-off-by: Tim Clark

Input: xpad - add Covert Forces edition of the Xbox One controller

2017-04-11T08:57:29+00:00

It is identical to the Xbox One controller but has a different product ID. Signed-off-by: Pavel Rojtberg Signed-off-by: Dmitry Torokhov Signed-off-by: Tim Clark

Input: xpad - re-send LED command on present event

2017-04-11T08:57:29+00:00

The controller only receives commands when its present. So for the correct LED to be lit the LED command has to be sent on the present event. Signed-off-by: Pavel Rojtberg Signed-off-by: Dmitry Torokhov Signed-off-by: Tim Clark

Input: xpad - set the LEDs properly on XBox Wireless controllers

2017-04-11T08:57:29+00:00

Based on Patch by Pierre-Loup A. Griffais : Add the logic to set the LEDs on XBox Wireless controllers. Command sequence found by sniffing the Windows data stream when plugging the device in. Updated based on comments on linux-input: unify codepaths in xpad_send_led_command for wired/ wireless controller. Also document command values for clarification. All values tested on Xbox 360 Wireless Controller. Signed-off-by: Pavel Rojtberg Signed-off-by: Dmitry Torokhov Signed-off-by: Tim Clark
