Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> firmware: qcom: scm: Mark get_wq_ctx() as atomic call<br /> <br /> Currently get_wq_ctx() is wrongly configured as a standard call. When two<br /> SMC calls are in sleep and one SMC wakes up, it calls get_wq_ctx() to<br /> resume the corresponding sleeping thread. But if get_wq_ctx() is<br /> interrupted, goes to sleep and another SMC call is waiting to be allocated<br /> a waitq context, it leads to a deadlock.<br /> <br /> To avoid this get_wq_ctx() must be an atomic call and can&amp;#39;t be a standard<br /> SMC call. Hence mark get_wq_ctx() as a fast call.
