Merge branch 'for-5.14/multitouch' into for-linus

2021-06-30T07:15:15Z

- patch series that ensures that hid-multitouch driver disables touch and button-press reporting on hid-mt devices during suspend when the device is not configured as a wakeup-source, from Hans de Goede

Merge branch 'for-5.14/core' into for-linus

2021-06-30T07:03:51Z

- device unbinding locking fix from Dmitry Torokhov - support for programmable buttons (mapping to KEY_MACRO# event codes) from Thomas Weißschuh - various other small fixes and code style improvements

HID: core: Add hid_hw_may_wakeup() function

2021-06-25T12:02:58Z

Add a hid_hw_may_wakeup() function, which is the equivalent of device_may_wakeup() for hid devices. In most cases this just returns device_may_wakeup(hdev->dev.parent), but for some ll-drivers this is not correct. E.g. usb_hid_driver instantiated hid devices have their parent set to the usb-interface to which the usb_hid_driver is bound, but the power/wakeup* sysfs attributes are part of the usb-device, which is the usb-interface's parent. For these special cases a new may_wakeup callback is added to hid_ll_driver, so that ll-drivers can override the default behavior.

HID: input: Add support for Programmable Buttons

2021-06-24T13:40:59Z

Map them to KEY_MACRO# event codes. These buttons are defined by HID as follows: "The user defines the function of these buttons to control software applications or GUI objects." This matches the semantics of the KEY_MACRO# input event codes that Linux supports. Also add support for HID "Named Array" collections. Also add hid-debug support for KEY_MACRO#.

HID: usbhid: fix info leak in hid_submit_ctrl

2021-05-05T13:52:34Z

In hid_submit_ctrl(), the way of calculating the report length doesn't take into account that report->size can be zero. When running the syzkaller reproducer, a report of size 0 causes hid_submit_ctrl) to calculate transfer_buffer_length as 16384. When this urb is passed to the usb core layer, KMSAN reports an info leak of 16384 bytes. To fix this, first modify hid_report_len() to account for the zero report size case by using DIV_ROUND_UP for the division. Then, call it from hid_submit_ctrl().

Merge branch 'for-5.13/plantronics' into for-linus

2021-04-29T19:44:07Z

- Workaround for broken behavior of Plantronics Blackwire from Maxim Mikityanskiy

HID: input: map battery capacity (00850065)

2021-04-07T11:15:17Z

This is the capacity in percentage, relative to design capacity. Specifically, it is present in Apple Magic Mouse 2. In contrast, usage 00850064 is also the capacity in percentage, but is relative to full capacity. It is not mapped here because I don't have such device.

HID: plantronics: Workaround for double volume key presses

2021-03-08T10:08:58Z

Plantronics Blackwire 3220 Series (047f:c056) sends HID reports twice for each volume key press. This patch adds a quirk to hid-plantronics for this product ID, which will ignore the second volume key press if it happens within 5 ms from the last one that was handled. The patch was tested on the mentioned model only, it shouldn't affect other models, however, this quirk might be needed for them too. Auto-repeat (when a key is held pressed) is not affected, because the rate is about 3 times per second, which is far less frequent than once in 5 ms.

HID: correct kernel-doc notation in

2021-01-26T13:24:26Z

Correct kernel-doc notation in HID header files (include/linux/hid*.h). Add notation (comments) where it is missing. Use the documented "Return:" notation for function return values. Fix a few typos/spellos. Signed-off-by: Randy Dunlap Cc: Jiri Kosina Cc: Benjamin Tissoires Cc: linux-input@vger.kernel.org Signed-off-by: Jiri Kosina

HID: Increase HID maximum report size to 16KB

2020-11-27T14:44:21Z

Currently the maximum HID report size which can be buffered by the kernel is 8KB. This is sufficient for the vast majority of HID devices on the market, as most HID reports are fairly small. However, some unusual devices such as the Elgate Stream Deck exist which use a report size slightly over 8KB for the image data that is sent to the device. Reports these large cannot be buffered by the regular HID subsystem currently, thus the only way to use such device is to bypass the HID subsystem entirely. This increases the maximum HID report size to 16KB, which should cover all sanely designed HID devices. Signed-off-by: Dean Camera Signed-off-by: Jiri Kosina
