[PATCH OLK-6.6] rseq: Protect event mask against membarrier IPI
by Wang Tao 06 Nov '25

06 Nov '25

From: Thomas Gleixner <tglx(a)linutronix.de> stable inclusion from stable-v6.6.113 commit d0d9fa88d7ab7e3ef6adc4cb4d1419b7c2d8016f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID561T Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 6eb350a2233100a283f882c023e5ad426d0ed63b ] rseq_need_restart() reads and clears task::rseq_event_mask with preemption disabled to guard against the scheduler. But membarrier() uses an IPI and sets the PREEMPT bit in the event mask from the IPI, which leaves that RMW operation unprotected. Use guard(irq) if CONFIG_MEMBARRIER is enabled to fix that.
