2024-09-13hid: cp2112: Use irq_get_trigger_type() helperJinjie Ruan
Use irq_get_trigger_type() to replace irq_get_irq_data() and then irqd_get_trigger_type(), if the irq data is NULL it will return 0. No functional changed.

2024-09-12HID: i2c-hid: ensure various commands do not interfere with each otherDmitry Torokhov
i2c-hid uses 2 shared buffers: command and "raw" input buffer for sending requests to peripherals and read data from peripherals when executing variety of commands. Such commands include reading of HID registers, requesting particular power mode, getting and setting reports and so on. Because all such requests use the same 2 buffers they should not execute simultaneously. Fix this by introducing "cmd_lock" mutex and acquire it whenever we needs to access ihid->cmdbuf or idid->rawbuf.

2024-09-10HID: wacom: Do not warn about dropped packets for first packetJason Gerecke
The driver currently assumes that the first sequence number it will see is going to be 0. This is not a realiable assumption and can break if, for example, the tablet has already been running for some time prior to the kernel driver connecting to the device. This commit initializes the expected sequence number to -1 and will only print the "Dropped" warning the it has been updated to a non-negative value.

2024-09-10HID: wacom: Support sequence numbers smaller than 16-bitJason Gerecke
The current dropped packet reporting assumes that all sequence numbers are 16 bits in length. This results in misleading "Dropped" messages if the hardware uses fewer bits. For example, if a tablet uses only 8 bits to store its sequence number, once it rolls over from 255 -> 0, the driver will still be expecting a packet "256". This patch adjusts the logic to reset the next expected packet to logical_minimum whenever it overflows beyond logical_maximum.

2024-08-29HID: hid-goodix: Fix type promotion bug in goodix_hid_get_raw_report()Dan Carpenter
The issue is GOODIX_HID_PKG_LEN_SIZE is defined as sizeof(u16) which is type size_t. However, goodix_hid_check_ack_status() returns negative error codes or potentially a positive but invalid length which is too small. So when we compare "if ((response_data_len <= GOODIX_HID_PKG_LEN_SIZE)" then negative error codes are type promoted to size_t and counted as a positive large value and treated as valid. It would have been easy enough to add some casting to avoid the type promotion, however this patch takes a more thourough approach and moves the length check into goodix_hid_check_ack_status(). Now the function only return negative error codes or zero on success and the length pointer is never set to an invalid length.

2024-08-29HID: hidraw: add HIDIOCREVOKE ioctlPeter Hutterer
There is a need for userspace applications to open HID devices directly. Use-cases include configuration of gaming mice or direct access to joystick devices. The latter is currently handled by the uaccess tag in systemd, other devices include more custom/local configurations or just sudo. A better approach is what we already have for evdev devices: give the application a file descriptor and revoke it when it may no longer access that device. This patch is the hidraw equivalent to the EVIOCREVOKE ioctl, see commit c7dc65737c9a ("Input: evdev - add EVIOCREVOKE ioctl") for full details.
