[PATCH OLK-6.6] sched: Fix race between yield_to() and try_to_wake_up()
by Xia Fukun 28 Nov '25

28 Nov '25

From: Tianchen Ding <dtcccc(a)linux.alibaba.com> mainline inclusion from mainline-v6.18-rc1 commit 5d808c78d97251af1d3a3e4f253e7d6c39fd871e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID8CE7 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- We met a SCHED_WARN in set_next_buddy(): __warn_printk set_next_buddy yield_to_task_fair yield_to kvm_vcpu_yield_to [kvm] ... After a short dig, we found the rq_lock held by yield_to() may not be exactly the rq that the target task belongs to. There is a race window against try_to_wake_up(). CPU0 target_task blocking on CPU1 lock rq0 & rq1 double check task_rq == p_rq, ok woken to CPU2 (lock task_pi & rq2) task_rq = rq2 yield_to_task_fair (w/o lock rq2) In this race window, yield_to() is operating the task w/o the correct lock. Fix this by taking task pi_lock first.
