2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds
This was done entirely with mindless brute force, using git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' | xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/' to convert the new alloc_obj() users that had a simple GFP_KERNEL argument to just drop that argument. Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2026-02-21treewide: Replace kmalloc with kmalloc_obj for non-scalar typesKees Cook
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org>
2025-06-17sysfs: treewide: switch back to bin_attribute::read()/write()Thomas Weißschuh
The bin_attribute argument of bin_attribute::read() is now const. This makes the _new() callbacks unnecessary. Switch all users back.

2024-12-11HID: roccat: lua: constify 'struct bin_attribute'Thomas Weißschuh
The sysfs core now allows instances of 'struct bin_attribute' to be moved into read-only memory. Make use of that to protect them against accidental or malicious modifications. Signed-off-by: Thomas Weißschuh <linux@weissschuh.net> Signed-off-by: Jiri Kosina <jkosina@suse.com>
2021-12-02HID: check for valid USB device for many HID driversGreg Kroah-Hartman
Many HID drivers assume that the HID device assigned to them is a USB device as that was the only way HID devices used to be able to be created in Linux. However, with the additional ways that HID devices can be created for many different bus types, that is no longer true, so properly check that we have a USB device associated with the HID device before allowing a driver that makes this assumption to claim it.

This patch removes the cast on data of type void* as it is not needed.

2013-01-03HID: Use module_hid_driver macroH Hartley Sweeten
Use the new module_hid_driver macro in all HID drivers that have a simple register/unregister init/exit. This also converts the hid drivers that test for a failure of hid_register_driver() and report the failure. Using module_hid_driver in those drivers removes the failure message.
