Sebastian Andrzej Siewior 76badb0a4d crypto: cryptd - Protect per-CPU resource by disabling BH. ... [ Upstream commit 91e8bcd7b4da182e09ea19a2c73167345fe14c98 ] The access to cryptd_queue::cpu_queue is synchronized by disabling preemption in cryptd_enqueue_request() and disabling BH in cryptd_queue_worker(). This implies that access is allowed from BH. If cryptd_enqueue_request() is invoked from preemptible context _and_ soft interrupt then this can lead to list corruption since cryptd_enqueue_request() is not protected against access from soft interrupt. Replace get_cpu() in cryptd_enqueue_request() with local_bh_disable() to ensure BH is always disabled. Remove preempt_disable() from cryptd_queue_worker() since it is not needed because local_bh_disable() ensures synchronisation. Fixes: 254eff7714 ("crypto: cryptd - Per-CPU thread implementation...")
