QAT_Engine/qat_events.c

Line 289 in 26b4d6c

int qat_wake_job(volatile ASYNC_JOB *job, int jobStatus)
use a pointer to ASYNC_JOB to get wait_ctx each time the driver ready, but wait_ctx may be got freed already when the async job canceled after received ASYNC_PAUSE in the main thread.
ASYNC_JOB doesn't have any protection for reusing wait_ctx across threads.
