The watchdog_timer can schedule tx_timeout_task and watchdog_work can also arm watchdog_timer. The process is shown below: ----------- timer schedules work ------------ cyttsp4_watchdog_timer() //timer handler schedule_work(&cd->watchdog_work) ----------- work arms timer ------------ cyttsp4_watchdog_work() //workqueue callback function cyttsp4_start_wd_timer() mod_timer(&cd->watchdog_timer, ...) Although del_timer_sync() and cancel_work_sync() are called in cyttsp4_remove(), the timer and workqueue could still be rearmed. As a result, the possible use after free bugs could happen. The process is shown below: (cleanup routine) | (timer and workqueue routine) cyttsp4_remove() | cyttsp4_watchdog_timer() //timer cyttsp4_stop_wd_timer() | schedule_work() del_timer_sync() | | cyttsp4_watchdog_work() //worker | cyttsp4_start_wd_timer() | mod_timer() cancel_work_sync() | | cyttsp4_watchdog_timer() //timer | schedule_work() del_timer_sync() | kfree(cd) //FREE | | cyttsp4_watchdog_work() // reschedule! | cd-> //USE This patch changes del_timer_sync() to timer_shutdown_sync(), which could prevent rearming of the timer from the workqueue.

First of all, previously the 16-bit magnitude was written as-is to the device which actually discarded the upper 8 bits since the device has 8-bit registers only. This meant that a strong_magnitude of 0xFF00 would result in 0. To correct this shift the strong_magnitude / weak_magnitude input values so we discard the lower 8 bits and keep the upper bits instead. Secondly the RTP mode that is used by default interprets the values as signed (2s complement), so 0x81 = 0%, 0x00 = 50%, 0x7F = 100%. This doesn't match the FF_RUMBLE interface at all, so let's tell the device to interpret the data as unsigned instead which gets us 0x00 = 0% and 0xFF = 100%. As last change switch ERM to using "Closed-Loop Mode, Unidirectional" instead of "Open-Loop Mode" since it's recommended by the datasheet compared to open loop and better matches our use case of 0% - 100% vibration.

When a hard IRQ is triggered, the soft IRQ, which decides if an actual pen down happened, should always be triggered. This enables the usage of "can_sleep" GPIO chips as "pen down" GPIO, as the value is not read during the hard IRQ anymore. This might be the case if the GPIO chip is an expander behind i2c.

The input subsystem doesn't currently have any unit tests, let's add a CONFIG_INPUT_KUNIT_TEST option that builds a test suite to be executed with the KUnit test infrastructure. For now, only three tests were added for some of the input core helper functions that are trivial to test: * input_test_polling: set/get poll interval and set-up a poll handler. * input_test_timestamp: set/get input event timestamps. * input_test_match_device_id: match a device by bus, vendor, product, version and events capable of handling. But having the minimal KUnit support allows to add more tests and suites as follow-up changes. The tests can be run with the following command: $ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/input/tests/ Signed-off-by:Javier Martinez Canillas <javierm@redhat.com> Tested-by:

Add a new driver for the Novatek i2c touchscreen controller as found on the Acer Iconia One 7 B1-750 tablet. Unfortunately the touchscreen controller model-number is unknown. Even with the tablet opened up it is impossible to read the model-number. Android calls this a "NVT-ts" touchscreen, but that may apply to other Novatek controller models too. This appears to be the same controller as the one supported by https://github.com/advx9600/android/blob/master/touchscreen/NVTtouch_Android4.0/NVTtouch.c but unfortunately that does not give us a model-number either.

Some third-party controllers, such as the HORPIAD FPS for Nintendo Switch and Gamesir-G3w, require a specific packet that the first-party XInput driver sends before it will start sending reports. It's not currently known what this packet does, but since the first-party driver always sends it's unlikely that this could cause issues with existing controllers. Co-authored-by:
