2026-02-21Convert 'alloc_obj' family to use the new default GFP_KERNEL argumentLinus Torvalds-21/+21
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-22/+22
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>

2025-12-18Input: palmas-pwrbutton - replace use of system_wq with system_dfl_wqMarco Crivellari-1/+1
Currently if a user enqueues a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistency cannot be addressed without refactoring the API. This patch continues the effort to refactor worqueue APIs, which has begun with the change introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This specific workload do not benefit from a per-cpu workqueue, so use the default unbound workqueue (system_dfl_wq) instead.

Struct ff_effect_compat is embedded twice inside uinput_ff_upload_compat, contains internal padding. In particular, there is a hole after struct ff_replay to satisfy alignment requirements for the following union member. Without clearing the structure, copy_to_user() may leak stack data to userspace. Initialize ff_up_compat to zero before filling valid fields.

2025-09-24Input: pm8941-pwrkey - disable wakeup for resin by defaultLuca Weiss-2/+10
'Resin' (*Res*et *In*put) is usually connected to a volume down button on devices, which is usually not expected to wake up the device from suspend. On the other hand, pwrkey should keep wakeup on. So do not enable wakeup for resin unless the "wakeup-source" property is specified in devicetree. Note, that this does change behavior by turning off wakeup by default for 'resin' and requiring a new dt property to be added to turn it on again. But since this is not expected behavior in the first place, and most users will not expect this, I'd argue this change is acceptable.

The driver called pwm_config() and pwm_enable() separately. Today both are wrappers for pwm_apply_might_sleep() and it's more effective to call this function directly and only once. Also don't configure the duty_cycle and period if the next operation is to disable the PWM so configure the PWM in max77693_haptic_enable(). With the direct use of pwm_apply_might_sleep() the need to call pwm_apply_args() in .probe() is now gone, too, so drop this one.

2025-06-30Input: max8997_haptic - optimize PWM configurationUwe Kleine-König-49/+47
Both pwm_config() and pwm_enable() are wrappers around pwm_apply_might_sleep(). Instead of calling this function twice only call it once without an intermediate step. Setup the PWM in max8997_haptic_enable() only where it was enabled historically. max8997_haptic_set_duty_cycle() is renamed accordingly to make it clear this function is only about the internal setup now. pwm_config() was called earlier back then, but that call has no effect on the hardware when the PWM is disabled, so delaying this configuration doesn't make a difference. As pwm_apply_might_sleep() is used now defining the whole state of the PWM, the call to pwm_apply_args() in .probe() can be dropped now, too.

W=1 builds warn that the data written to 'tc_name' is truncated for theoretical strings such as "channel-2147483646". Solve this problem by replacing snprintf() with scnprintf() so that the return value corresponds to what was actually written. In practice, the largest string that will be written is "channel-8", and the return value is not actually evaluated. Instead, this patch ultimately removes the warning without unnecessarily increasing the size of 'tc_name' from 10 bytes.
