Merge tag 'locking-core-2026-06-14' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tipPull locking updates from Ingo Molnar: "Futex updates: - Optimize futex hash bucket access patterns (Peter Zijlstra) - Large series to address the robust futex unlock race for real, by Thomas Gleixner: "The robust futex unlock mechanism is racy in respect to the clearing of the robust_list_head::list_op_pending pointer because unlock and clearing the pointer are not atomic. The race window is between the unlock and clearing the pending op pointer. If the task is forced to exit in this window, exit will access a potentially invalid pending op pointer when cleaning up the robust list. That happens if another task manages to unmap the object containing the lock before the cleanup, which results in an UAF. In the worst case this UAF can lead to memory corruption when unrelated content has been mapped to the same address by the time the access happens. User space can't solve this problem without help from the kernel. This series provides the kernel side infrastructure to help it along: 1) Combined unlock, pointer clearing, wake-up for the contended case 2) VDSO based unlock and pointer clearing helpers with a fix-up function in the kernel when user space was interrupted within the critical section. ... with help by André Almeida: - Add a note about robust list race condition (André Almeida) - Add self-tests for robust release operations (André Almeida) Context analysis updates: - Implement context analysis for 'struct rt_mutex'.

c06cd66387da92e6cdac44e16c7b5ef9219c53ac - percpu: Sanitize __percpu_qual include hell

Tue, 02 Jun 2026 11:09:21 +0200

percpu: Sanitize __percpu_qual include hellSlapping __percpu_qual into the next available header is sloppy at best.It's required by __percpu which is defined in compiler_types.h and that ismeant to be included without requiring a boatload of other headers so thata struct or function declaration can contain a __percpu qualifier w/ofurther prerequisites.This implicit dependency on linux/percpu.h makes that impossible and causesa major problem when trying to separate headers.Create asm/percpu_types.h and move it there. Include that fromcompiler_types.h and the whole recursion problem goes away.Fix up UM so it uses the generic header and includes it in the UM_HOSTbuild, which pulls in compiler_types.h. The USER_CFLAGS fix was suggestedby Richard.Signed-off-by: Thomas Gleixner Signed-off-by: Peter Zijlstra (Intel) Link: https://patch.msgid.link/20260602090535.254874125@kernel.org List of files: /linux/arch/um/include/asm/Kbuild
