HID: add per device quirk to force bind to hid-generic

2024-12-14T19:03:39Z

[ Upstream commit 645c224ac5f6e0013931c342ea707b398d24d410 ] We already have the possibility to force not binding to hid-generic and rely on a dedicated driver, but we couldn't do the other way around. This is useful for BPF programs where we are fixing the report descriptor and the events, but want to avoid a specialized driver to come after BPF which would unwind everything that is done there.

HID: core: zero-initialize the report buffer

2024-10-29T14:44:42Z

Since the report buffer is used by all kinds of drivers in various ways, let's zero-initialize it during allocation to make sure that it can't be ever used to leak kernel memory via specially-crafted report.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

- Constification of report descriptors so drivers can use read-only memory when declaring report descriptors fixups (Thomas Weißschuh)

HID: constify params and return value of fetch_item()

2024-08-27T14:18:51Z

fetch_item() does not modify the descriptor it operates on. As a prerequisite for the constification of hid_driver::dev_rdesc, mark the parameters and return value of fetch_item() as const. Also adapt the variable types in the callers to match this constification.

The parameter is never modified, so mark it as const. This is a prerequisite for constification changes in the HID core. Signed-off-by: Thomas Weißschuh Link: https://patch.msgid.link/20240803-hid-const-fixup-v2-2-f53d7a7b29d8@weissschuh.net Signed-off-by: Benjamin Tissoires

HID: core: add helper for finding a field with a certain usage

2024-08-02T10:42:23Z

This helper will allow HID drivers to easily determine if they should bind to a hid_device by checking for the prescence of a certain field when its ID is not enough, which can be the case on USB devices with multiple interfaces and/or configurations. Convert google-hammer driver to use it, and remove now superfluous hammer_has_usage().

Pull driver core updates from Greg KH: "Here is the big set of driver core changes for 6.11-rc1. Lots of stuff in here, with not a huge diffstat, but apis are evolving which required lots of files to be touched. Highlights of the changes in here are: - platform remove callback api final fixups (Uwe took many releases to get here, finally!) - Rust bindings for basic firmware apis and initial driver-core interactions. It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory. We aren't there yet, but are getting closer. - minor devres cleanups and fixes found by code inspection - arch_topology minor changes - other minor driver core cleanups All of these have been in linux-next for a very long time with no reported problems" * tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (55 commits) ARM: sa1100: make match function take a const pointer sysfs/cpu: Make crash_hotplug attribute world-readable dio: Have dio_bus_match() callback take a const * zorro: make match function take a const pointer driver core: module: make module_[add|remove]_driver take a const * driver core: make driver_find_device() take a const * driver core: make driver_[create|remove]_file take a const * firmware_loader: fix soundness issue in `request_internal` firmware_loader: annotate doctests as `no_run` devres: Correct code style for functions that return a pointer type devres: Initialize an uninitialized struct member devres: Fix memory leakage caused by driver API devm_free_percpu() devres: Fix devm_krealloc() wasting memory driver core: platform: Switch to use kmemdup_array() driver core: have match() callback in struct bus_type take a const * MAINTAINERS: add Rust device abstractions to DRIVER CORE device: rust: improve safety comments MAINTAINERS: add Danilo as FIRMWARE LOADER maintainer MAINTAINERS: add Rust FW abstractions to FIRMWARE LOADER firmware: rust: improve safety comments ...
