2024-09-09fs: Fix file_set_fowner LSM hook inconsistenciesMickaël Salaün
The fcntl's F_SETOWN command sets the process that handle SIGIO/SIGURG for the related file descriptor. Before this change, the file_set_fowner LSM hook was always called, ignoring the VFS logic which may not actually change the process that handles SIGIO (e.g. TUN, TTY, dnotify), nor update the related UID/EUID. Moreover, because security_file_set_fowner() was called without lock (e.g. f_owner.lock), concurrent F_SETOWN commands could result to a race condition and inconsistent LSM states (e.g. SELinux's fown_sid) compared to struct fown_struct's UID/EUID. This change makes sure the LSM states are always in sync with the VFS state by moving the security_file_set_fowner() call close to the UID/EUID updates and using the same f_owner.lock . Rename f_modown() to __f_setown() to simplify code.

2024-09-09io_uring/sqpoll: do not allow pinning outside of cpusetFelix Moessbauer
The submit queue polling threads are userland threads that just never exit to the userland. When creating the thread with IORING_SETUP_SQ_AFF, the affinity of the poller thread is set to the cpu specified in sq_thread_cpu. However, this CPU can be outside of the cpuset defined by the cgroup cpuset controller. This violates the rules defined by the cpuset controller and is a potential issue for realtime applications. In b7ed6d8ffd6 we fixed the default affinity of the poller thread, in case no explicit pinning is required by inheriting the one of the creating task. In case of explicit pinning, the check is more complicated, as also a cpu outside of the parent cpumask is allowed. We implemented this by using cpuset_cpus_allowed (that has support for cgroup cpusets) and testing if the requested cpu is in the set.

The DPI display interface feeds the external display pipeline. However the pipeline representation is currently incomplete. Efforts are still under way to come up with a way to represent the "creative" repurposing of the DP bridge chip's internal output mux, which is meant to support USB type-C orientation changes, to output to one of two type-C ports. Until that is finalized, the external display can't be fully described, and thus won't work. Even worse, the half complete graph potentially confuses the OS, breaking the internal display as well. Disable the external display interface across the whole Corsola family until the DP / USB Type-C muxing graph binding is ready.

2024-09-09debugobjects: Remove redundant checks in fill_pool()Zhen Lei
fill_pool() checks locklessly at the beginning whether the pool has to be refilled. After that it checks locklessly in a loop whether the free list contains objects and repeats the refill check. If both conditions are true, it acquires the pool lock and tries to move objects from the free list to the pool repeating the same checks again. There are two redundant issues with that: 1) The repeated check for the fill condition 2) The loop processing The repeated check is pointless as it was just established that fill is required. The condition has to be re-evaluated under the lock anyway. The loop processing is not required either because there is practically zero chance that a repeated attempt will succeed if the checks under the lock terminate the moving of objects. Remove the redundant check and replace the loop with a simple if condition.

2024-09-09debugobjects: Fix conditions in fill_pool()Zhen Lei
fill_pool() uses 'obj_pool_min_free' to decide whether objects should be handed back to the kmem cache. But 'obj_pool_min_free' records the lowest historical value of the number of objects in the object pool and not the minimum number of objects which should be kept in the pool. Use 'debug_objects_pool_min_level' instead, which holds the minimum number which was scaled to the number of CPUs at boot time.

1. Both debug_objects_pool_min_level and debug_objects_pool_size are read-only after initialization, change attribute '__read_mostly' to '__ro_after_init', and remove '__data_racy'. 2. Many global variables are read in the debug_stats_show() function, but didn't mask KCSAN's detection. Add '__data_racy' for them.

2024-09-09perf: arm_pmuv3: Use BR_RETIRED for HW branch event if enabledIlkka Koskinen
The PMU driver attempts to use PC_WRITE_RETIRED for the HW branch event, if enabled. However, PC_WRITE_RETIRED counts only taken branches, whereas BR_RETIRED counts also non-taken ones. Furthermore, perf uses HW branch event to calculate branch misses ratio, implying BR_RETIRED is the correct event to count. We keep PC_WRITE_RETIRED still as an option in case BR_RETIRED isn't implemented.
