From: Sean Anderson <sean.anderson(a)linux.dev> stable inclusion from stable-v5.10.215 commit 32edca2f03a6cc42c650ddc3ad83d086e3f365d1 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q9CD CVE: CVE-2024-35819 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit fbec4e7fed89b579f2483041fabf9650fb0dd6bc ] smp_call_function always runs its callback in hard IRQ context, even on PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock for cgr_lock to ensure we aren't waiting on a sleeping task. Although this bug has existed for a while, it was not apparent until commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change") which invokes smp_call_function_single via qman_update_cgr_safe every time a link goes up or down.
