Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> soc: fsl: qbman: Use raw spinlock for cgr_lock<br /> <br /> smp_call_function always runs its callback in hard IRQ context, even on<br /> PREEMPT_RT, where spinlocks can sleep. So we need to use a raw spinlock<br /> for cgr_lock to ensure we aren&amp;#39;t waiting on a sleeping task.<br /> <br /> Although this bug has existed for a while, it was not apparent until<br /> commit ef2a8d5478b9 ("net: dpaa: Adjust queue depth on rate change")<br /> which invokes smp_call_function_single via qman_update_cgr_safe every<br /> time a link goes up or down.
