HID: fix HID device resource race between HID core and debugging support

2023-12-03T06:33:04+00:00

[ Upstream commit fc43e9c857b7aa55efba9398419b14d9e35dcc7d ] hid_debug_events_release releases resources bound to the HID device instance. hid_device_release releases the underlying HID device instance potentially before hid_debug_events_release has completed releasing debug resources bound to the same HID device instance. Reference count to prevent the HID device instance from being torn down preemptively when HID debugging support is used. When count reaches zero, release core resources of HID device instance using hiddev_free. The crash: [ 120.728477][ T4396] kernel BUG at lib/list_debug.c:53!

HID: Add Mapping for System Microphone Mute

2022-12-20T14:32:46+00:00

HUTRR110 added a new usage code for a key that is supposed to mute/unmute microphone system-wide. Map the new usage code(0x01 0xa9) to keycode KEY_MICMUTE. Additionally hid-debug is adjusted to recognize this keycode as well. Signed-off-by: Jingyuan Liang Reviewed-by: Dmitry Torokhov Signed-off-by: Jiri Kosina

HID: add mapping for camera access keys

2022-11-23T01:50:36+00:00

HUTRR72 added 3 new usage codes for keys that are supposed to enable, disable and toggle camera access. These are useful, considering many laptops today have key(s) for toggling access to camera. This patch adds new key definitions for KEY_CAMERA_ACCESS_ENABLE, KEY_CAMERA_ACCESS_DISABLE and KEY_CAMERA_ACCESS_TOGGLE. Additionally hid-debug is adjusted to recognize this new usage codes as well.

HID: hid-debug: clean up snprintf() checks in hid_resolv_usage()

2021-09-22T09:49:17+00:00

The snprintf() limits are complicated and slightly wrong when it does: max(0, HID_DEBUG_BUFSIZE - len - 1) The "- 1" should not be there. It means we can't use the last byte of the buffer. If we change the first snprintf() to scnprintf() then we can remove the max(). At the start of the function the strlen(buf) is going always going to be < HID_DEBUG_BUFSIZE so that is safe. If it were > HID_DEBUG_BUFSIZE then that would result in a WARN(). Signed-off-by: Dan Carpenter Signed-off-by: Jiri Kosina
