This will lead to an invalid prev be returned. Generally this shouldn't matter as the caller should treat an error as indicating state is now invalidated, however unfortunately apply_mlockall_flags() does not check for errors and assumes that mlock_fixup() correctly maintains prev even if an error were to occur.

by Javier Carrasco

This series releases the 'soc' device_node when it is no longer required by adding the missing calls to of_node_put() to make the fix compatible with all affected stable kernels. Then, the more robust approach via cleanup attribute is used to simplify the handling and prevent issues if the loop gets new execution paths. These issues were found while analyzing the code, and the patches have been successfully compiled, but not tested on real hardware as I don't have access to it.

[PATCH] drm/i915/color: Stop using non-posted DSB writes for legacy LUT

by Ville Syrjala

From: Ville Syrjälä <ville.syrjala(a)linux.intel.com> Apparently using non-posted DSB writes to update the legacy LUT can cause CPU MMIO accesses to fail on TGL.

[PATCH] arm64/signal: Avoid corruption of SME state when entering signal handler

by Mark Brown

When we enter a signal handler we exit streaming mode in order to ensure that signal handlers can run normal FPSIMD code, and while we're at it we also clear PSTATE.ZA. Currently the code in setup_return() updates both the in memory copy of the state and the register state. Not only is this redundant it can also lead to corruption if we are preempted. Consider two tasks on one CPU: A: Begins signal entry in kernel mode, is preempted prior to SMSTOP. B: Using SM and/or ZA in userspace with register state current on the CPU, is preempted. A: Scheduled in, no register state changes made as in kernel mode. A: Executes SMSTOP, modifying live register state. A: Scheduled out. B: Scheduled in, fpsimd_thread_switch() sees the register state on the CPU is tracked as being that for task B so the state is not reloaded prior to returning to userspace. Task B is now running with SM and ZA incorrectly cleared. Fix this by check TIF_FOREIGN_FPSTATE and only updating one of the live register context or the in memory copy when entering a signal handler. Since this needs to happen atomically and all code that atomically accesses FP state is in fpsimd.c also move the code there to ensure consistency. This race has been observed intermittently with fp-stress, especially with preempt disabled.

[PATCH net] mptcp: Ensure RCU read lock is held when calling mptcp_sched_find()

by Breno Leitao

The mptcp_sched_find() function must be called with the RCU read lock held, as it accesses RCU-protected data structures. This requirement was not properly enforced in the mptcp_init_sock() function, leading to a RCU list traversal in a non-reader section error when CONFIG_PROVE_RCU_LIST is enabled. net/mptcp/sched.c:44 RCU-list traversed in non-reader section!! Fix it by acquiring the RCU read lock before calling the mptcp_sched_find() function. This ensures that the function is invoked with the necessary RCU protection in place, as it accesses RCU-protected data structures. Additionally, the patch breaks down the mptcp_init_sched() call into smaller parts, with the RCU read lock only covering the specific call to mptcp_sched_find(). This helps minimize the critical section, reducing the time during which RCU grace periods are blocked. The mptcp_sched_list_lock is not held in this case, and it is not clear if it is necessary.
