The data race happens on ps2dev->cmdcnt and ps2dev->cmdbuf contents. __ps2_command reads that data concurrently with the interrupt handler. As the result, for example, if a response arrives just after the timeout, __ps2_command can copy out garbage from ps2dev->cmdbuf but then see that ps2dev->cmdcnt is 0 and return success. Stop the interrupt handler with serio_pause_rx() before reading the results. The data race was found with KernelThreadSanitizer (KTSAN).

Commit b6d30968 (Input: uinput - switch to using for_each_set_bit()) switched driver to use for_each_set_bit(). However during initial write of the uinput structure that contains min/max data for all possible axes none of them are reflected in dev->absbit yet and so we were skipping over all of them and were not allocating absinfo memory which caused crash later when driver tried to sens EV_ABS events: <1>[ 15.064330] BUG: unable to handle kernel NULL pointer dereference at 0000000000000024 <1>[ 15.064336] IP: [<ffffffff8163f142>] input_handle_event+0x232/0x4e0 <4>[ 15.064343] PGD 0 <4>[ 15.064345] Oops: 0000 [#1] SMP Fixes: b6d30968 Cc: stable@vger.kernel.org Reported-by: NStephen Chandler Paul <cpaul@redhat.com> Tested-by: NStephen Chandler Paul <cpaul@redhat.com> Signed-off-by: NDmitry Torokhov <dmitry.torokhov@gmail.com>

The Asus X456UA has an ELAN1000 touchpad with IAP version 0xe. This is unknown to elan_get_fwinfo() so driver probe fails and I am left with an unusable touchpad. However, the fwinfo is not required for general driver usage, it is only needed if the user decides to upload new firmware. Adjust the driver so that we do not abort probe when we encounter unexpected IAP version, but rather warn user that firmware update feature of the driver will not work.

We've got bug reports showing the old systemd-logind (at least system-210) aborting unexpectedly, and this turned out to be because of an invalid error code from close() call to evdev devices. close() is supposed to return only either EINTR or EBADFD, while the device returned ENODEV. logind was overreacting to it and decided to kill itself when an unexpected error code was received. What a tragedy. The bad error code comes from flush fops, and actually evdev_flush() returns ENODEV when device is disconnected or client's access to it is revoked. But in these cases the fact that flush did not actually happen is not an error, but rather normal behavior. For non-disconnected devices result of flush is also not that interesting as there is no potential of data loss and even if it fails application has no way of handling the error. Because of that we are better off always returning success from evdev_flush(). Also returning EINTR from flush()/close() is discouraged (as it is not clear how application should handle this error), so let's stop taking evdev->mutex interruptibly.

Bit 2 of the mode byte has dual meaning: it can disable reporting of gestures when touchpad works in Relative mode or normal Absolute mode, or it can enable so called Extended W-Mode when touchpad uses enhanced Absolute mode (W-mode). The extended W-Mode confuses our driver and causes missing button presses on some Thinkpads (x250, T450s), so let's make sure we do not enable it. Also, according to the spec W mode "... bit is defined only in Absolute mode on pads whose capExtended capability bit is set. In Relative mode and in TouchPads without this capability, the bit is reserved and should be left at 0.", so let's make sure we respect this requirement as well.
