2024-09-12HID: i2c-hid: ensure various commands do not interfere with each otherDmitry Torokhov1-15/+27
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.

2024-08-29HID: hidraw: add HIDIOCREVOKE ioctlPeter Hutterer3-4/+37
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.

2024-08-27HID: change return type of report_fixup() to constThomas Weißschuh51-68/+68
By allowing the drivers to return a "const *" they can constify their static report arrays. This makes it clear to driver authors that the HID core will not modify those reports and they can be reused for multiple devices. Furthermore security is slightly improved as those reports are protected against accidental or malicious modifications.

2024-08-19hid: intel-ish-hid: Add support for vendor customized firmware loadingZhang Lixu2-3/+103
Enhance the firmware loader to support the loading of vendor-specific customized firmware for the Intel Integrated Sensor Hub (ISH). The loader now constructs firmware file names based on the DMI_SYS_VENDOR, DMI_PRODUCT_NAME, and DMI_PRODUCT_SKU information in Desktop Management Interface (DMI). The loader will attempt to load the firmware files following a specific naming convention in sequence. If successful, it will skip the remaining files. For more details, please refer to Documentation/hid/intel-ish-hid.rst.

2024-08-19HID: intel-ish-hid: Use CPU generation string in driver_dataZhang Lixu3-9/+30
ISH allows vendors to customize ISH firmware. To differentiate different vendors and load the correct firmware, Intel defined a firmware file name format. As part of the filename, there is a "generation" string. To load correct format the driver must know the generation name to create file name. In the absence of any vendor specific firmware, default ISH firmware is loaded. Currently full ISH firmware file name is stored as part of driver data. This file name already includes the generation name. For example, for Lunar Lake, the name is ish_lnlm.bin, where "lnlm" is the generation. So instead of storing both generation name and ISH default firmware file name, just store generation name and create the default ISH firmware file name string during initialization. No functional changes are expected. Signed-off-by: Zhang Lixu <lixu.zhang@intel.com> Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jiri Kosina <jkosina@suse.com>
