HID: Fix assumption that devices have inputs

2019-10-03T19:36:40+00:00

The syzbot fuzzer found a slab-out-of-bounds write bug in the hid-gaff driver. The problem is caused by the driver's assumption that the device must have an input report. While this will be true for all normal HID input devices, a suitably malicious device can violate the assumption. The same assumption is present in over a dozen other HID drivers. This patch fixes them by checking that the list of hid_inputs for the hid_device is nonempty before allowing it to be used.

Bluetooth: hidp: Fix assumptions on the return value of hidp_send_message

2019-09-06T13:55:40+00:00

hidp_send_message was changed to return non-zero values on success, which some other bits did not expect. This caused spurious errors to be propagated through the stack, breaking some drivers, such as hid-sony for the Dualshock 4 in Bluetooth mode. As pointed out by Dan Carpenter, hid-microsoft directly relied on that assumption as well.

HID: microsoft: support the Surface Dial

2018-07-17T13:33:47+00:00

The tool works nicely with hid-generic, but it ends up creating 9 different input nodes with most of them only having ABS_MISC set. Filter the axis out, which reduces the amount of devices to 2. One is the proper System Multi-axis collection, the other exported device seems to provide SLEEP and POWER Key, not sure how one can trigger those events though. Filtering the ABS_X and ABS_Y axes also prevents udev to detect this as a touchscreen. Acked-by: Peter Hutterer Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina

Since commit 8fe89ef076fa1 ("HID: multitouch: enable the Surface 3 Type Cover to report multitouch data"), the TypeCover can be properly handled by hid-multitouch and don't require any special quirk in the kernel.
