2024-11-05char: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers matched by the "CHAR and MISC DRIVERS" maintainer's entry to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-11-05nvmem: Add R-Car E-FUSE driverGeert Uytterhoeven
R-Car Gen4 SoCs contain fuses indicating hardware support or hardware (e.g. tuning) parameters. Add a driver to access the state of the fuses. This supports two types of hardware fuse providers: 1. E-FUSE non-volatile memory accessible through the Pin Function Controller on R-Car V3U and S4-8, 2. E-FUSE non-volatile memory accessible through OTP_MEM on R-Car V4H and V4M. The state of the cells can be read using the NVMEM framework, either from kernel space (e.g. by the Renesas UFSHCD driver), or from userspace.

This means all function graph hooks that happen while that idle task is running (including in interrupt mode) will have all its events dropped. Switch over to the CPU hotplug mechanism that will have any newly brought on line CPU get a callback that can allocate the shadow stack for its idle task. - Fix allocation size of the ret_stack_list array When function graph tracing converted over to allowing more than one user at a time, it had to convert its shadow stack from an array of ret_stack structures to an array of unsigned longs. The shadow stacks are allocated in batches of 32 at a time and assigned to every running task. The batch is held by the ret_stack_list array. But when the conversion happened, instead of allocating an array of 32 pointers, it was allocated as a ret_stack itself (PAGE_SIZE). This ret_stack_list gets passed to a function that iterates over what it believes is its size defined by the FTRACE_RETSTACK_ALLOC_SIZE macro (which is 32). Luckily (PAGE_SIZE) is greater than 32 * sizeof(long), otherwise this would have been an array overflow. This still should be fixed and the ret_stack_list should be allocated to the size it is expected to be as someday it may end up being bigger than SHADOW_STACK_SIZE" * tag 'ftrace-v6.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: fgraph: Allocate ret_stack_list with proper size fgraph: Use CPU hotplug mechanism to initialize idle shadow stacks

2024-10-18fgraph: Allocate ret_stack_list with proper sizeSteven Rostedt
The ret_stack_list is an array of ret_stack shadow stacks for the function graph usage. When the first function graph is enabled, all tasks in the system get a shadow stack. The ret_stack_list is a 32 element array of pointers to these shadow stacks. It allocates the shadow stack in batches (32 stacks at a time), assigns them to running tasks, and continues until all tasks are covered. When the function graph shadow stack changed from an array of ftrace_ret_stack structures to an array of longs, the allocation of ret_stack_list went from allocating an array of 32 elements to just a block defined by SHADOW_STACK_SIZE. Luckily, that's defined as PAGE_SIZE and is much more than enough to hold 32 pointers. But it is way overkill for the amount needed to allocate. Change the allocation of ret_stack_list back to a kcalloc() of FTRACE_RETSTACK_ALLOC_SIZE pointers.

2024-10-18fgraph: Use CPU hotplug mechanism to initialize idle shadow stacksSteven Rostedt
The function graph infrastructure allocates a shadow stack for every task when enabled. This includes the idle tasks. The first time the function graph is invoked, the shadow stacks are created and never freed until the task exits. This includes the idle tasks. Only the idle tasks that were for online CPUs had their shadow stacks created when function graph tracing started. If function graph tracing is enabled and a CPU comes online, the idle task representing that CPU will not have its shadow stack created, and all function graph tracing for that idle task will be silently dropped. Instead, use the CPU hotplug mechanism to allocate the idle shadow stacks. This will include idle tasks for CPUs that come online during tracing. This issue can be reproduced by: # cd /sys/kernel/tracing # echo 0 > /sys/devices/system/cpu/cpu1/online # echo 0 > set_ftrace_pid # echo function_graph > current_tracer # echo 1 > options/funcgraph-proc # echo 1 > /sys/devices/system/cpu/cpu1 # grep '<idle>' per_cpu/cpu1/trace | head Before, nothing would show up. After: 1) <idle>-0 | 0.811 us | __enqueue_entity(); 1) <idle>-0 | 5.626 us | } /* enqueue_entity */ 1) <idle>-0 | | dl_server_update_idle_time() { 1) <idle>-0 | | dl_scaled_delta_exec() { 1) <idle>-0 | 0.450 us | arch_scale_cpu_capacity(); 1) <idle>-0 | 1.242 us | } 1) <idle>-0 | 1.908 us | } 1) <idle>-0 | | dl_server_start() { 1) <idle>-0 | | enqueue_dl_entity() { 1) <idle>-0 | | task_contending() { Note, if tracing stops and restarts, the old way would then initialize the onlined CPUs.

The possible negative errno from device_property_count_u32() was never checked, which was an oversight left from converting to it from the of_property as part of the review fixes. Re-add the correct handling of the absent property, in which case zero touchkeys should be assumed, which would disable the feature.

Pull io_uring fixes from Jens Axboe: - Fix a regression this merge window where cloning of registered buffers didn't take into account the dummy_ubuf - Fix a race with reading how many SQRING entries are available, causing userspace to need to loop around io_uring_sqring_wait() rather than being able to rely on SQEs being available when it returned - Ensure that the SQPOLL thread is TASK_RUNNING before running task_work off the cancelation exit path * tag 'io_uring-6.12-20241018' of git://git.kernel.dk/linux: io_uring/sqpoll: ensure task state is TASK_RUNNING when running task_work io_uring/rsrc: ignore dummy_ubuf for buffer cloning io_uring/sqpoll: close race on waiting for sqring entries
