2024-03-07Input: synaptics-rmi4 - fix UAF of IRQ domain on driver removalMathias Krause
Calling irq_domain_remove() will lead to freeing the IRQ domain prematurely. The domain is still referenced and will be attempted to get used via rmi_free_function_list() -> rmi_unregister_function() -> irq_dispose_mapping() -> irq_get_irq_data()'s ->domain pointer. With PaX's MEMORY_SANITIZE this will lead to an access fault when attempting to dereference embedded pointers, as in Torsten's report that was faulting on the 'domain->ops->unmap' test. Fix this by releasing the IRQ domain only after all related IRQs have been deactivated.

2024-03-05Revert "Input: bcm5974 - check endpoint type before starting traffic"Javier Carrasco
This patch intended to fix an well-knonw issue in old drivers where the endpoint type is taken for granted, which is often triggered by fuzzers. That was the case for this driver [1], and although the fix seems to be correct, it uncovered another issue that leads to a regression [2], if the endpoints of the current interface are checked. The driver makes use of endpoints that belong to a different interface rather than the one it binds (it binds to the third interface, but also accesses an endpoint from a different one). The driver should claim the interfaces it requires, but that is still not the case. Given that the regression is more severe than the issue found by syzkaller, the best approach is reverting the patch that causes the regression, and trying to fix the underlying problem before checking the endpoint types again. Note that reverting this patch will probably trigger the syzkaller bug at some point. This reverts commit 2b9c3eb32a699acdd4784d6b93743271b4970899.

2024-02-02Input: i8042 - add Fujitsu Lifebook U728 to i8042 quirk tableSzilard Fabian
Another Fujitsu-related patch. In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728 refuses to work and it's not possible to type for example a dm-crypt passphrase without the help of an external keyboard. i8042.nomux kernel parameter resolves this issue but using that a PS/2 mouse is detected. This input device is unused even when the i2c-hid-acpi kernel module is blacklisted making the integrated ELAN touchpad (04F3:3092) not working at all. So this notebook uses a hid-over-i2c touchpad which is managed by the i2c_designware input driver. Since you can't find a PS/2 mouse port on this computer and you can't connect a PS/2 mouse to it even with an official port replicator I think it's safe to not use the PS/2 mouse port at all.

When closing the laptop lid with an external screen connected, the mouse pointer has a constant movement to the lower right corner. Opening the lid again stops this movement, but after that the touchpad does no longer register clicks. The touchpad is connected both via i2c-hid and PS/2, the predecessor of this device (NS70MU) has the same layout in this regard and also strange behaviour caused by the psmouse and the i2c-hid driver fighting over touchpad control.

2024-02-01Input: atkbd - skip ATKBD_CMD_SETLEDS when skipping ATKBD_CMD_GETIDHans de Goede
After commit 936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in translated mode") the keyboard on Dell XPS 13 9350 / 9360 / 9370 models has stopped working after a suspend/resume. The problem appears to be that atkbd_probe() fails when called from atkbd_reconnect() on resume, which on systems where ATKBD_CMD_GETID is skipped can only happen by ATKBD_CMD_SETLEDS failing. ATKBD_CMD_SETLEDS failing because ATKBD_CMD_GETID was skipped is weird, but apparently that is what is happening. Fix this by also skipping ATKBD_CMD_SETLEDS when skipping ATKBD_CMD_GETID.

2024-01-31Input: bcm5974 - check endpoint type before starting trafficJavier Carrasco
syzbot has found a type mismatch between a USB pipe and the transfer endpoint, which is triggered by the bcm5974 driver[1]. This driver expects the device to provide input interrupt endpoints and if that is not the case, the driver registration should terminate. Repros are available to reproduce this issue with a certain setup for the dummy_hcd, leading to an interrupt/bulk mismatch which is caught in the USB core after calling usb_submit_urb() with the following message: "BOGUS urb xfer, pipe 1 != type 3" Some other device drivers (like the appletouch driver bcm5974 is mainly based on) provide some checking mechanism to make sure that an IN interrupt endpoint is available. In this particular case the endpoint addresses are provided by a config table, so the checking can be targeted to the provided endpoints. Add some basic checking to guarantee that the endpoints available match the expected type for both the trackpad and button endpoints. This issue was only found for the trackpad endpoint, but the checking has been added to the button endpoint as well for the same reasons. Given that there was never a check for the endpoint type, this bug has been there since the first implementation of the driver (f89bd95c5c94).

2024-01-30Input: xpad - add Lenovo Legion Go controllersBrenton Simpson
The Lenovo Legion Go is a handheld gaming system, similar to a Steam Deck. It has a gamepad (including rear paddles), 3 gyroscopes, a trackpad, volume buttons, a power button, and 2 LED ring lights. The Legion Go firmware presents these controls as a USB hub with various devices attached. In its default state, the gamepad is presented as an Xbox controller connected to this hub. (By holding a combination of buttons, it can be changed to use the older DirectInput API.) This patch teaches the existing Xbox controller module `xpad` to bind to the controller in the Legion Go, which enables support for the: - directional pad, - analog sticks (including clicks), - X, Y, A, B, - start and select (or menu and capture), - shoulder buttons, and - rumble. The trackpad, touchscreen, volume controls, and power button are already supported via existing kernel modules. Two of the face buttons, the gyroscopes, rear paddles, and LEDs are not. After this patch lands, the Legion Go will be mostly functional in Linux, out-of-the-box. The various components of the USB hub can be synthesized into a single logical controller (including the additional buttons) in userspace with [Handheld Daemon](https://github.com/hhd-dev/hhd), which makes the Go fully functional.

2024-01-19Input: goodix - accept ACPI resources with gpio_count == 3 && gpio_int_idx == 0Hans de Goede
Some devices list 3 Gpio resources in the ACPI resource list for the touchscreen: 1. GpioInt resource pointing to the GPIO used for the interrupt 2. GpioIo resource pointing to the reset GPIO 3. GpioIo resource pointing to the GPIO used for the interrupt Note how the third extra GpioIo resource really is a duplicate of the GpioInt provided info. Ignore this extra GPIO, treating this setup the same as gpio_count == 2 && gpio_int_idx == 0 fixes the touchscreen not working on the Thunderbook Colossus W803 rugged tablet and likely also on the CyberBook_T116K.
