2017-07-12crypto: caam - fix signals handlingHoria Geantă2-2/+2
Driver does not properly handle the case when signals interrupt wait_for_completion_interruptible(): -it does not check for return value -completion structure is allocated on stack; in case a signal interrupts the sleep, it will go out of scope, causing the worker thread (caam_jr_dequeue) to fail when it accesses it wait_for_completion_interruptible() is replaced with uninterruptable wait_for_completion(). We choose to block all signals while waiting for I/O (device executing the split key generation job descriptor) since the alternative - in order to have a deterministic device state - would be to flush the job ring (aborting *all* in-progress jobs).
