Hi, Looked at asynchronous support in Cryptodev-1.5 and found that it is getting in following flow cryptask_routine calling crypto_run. Now in crypto_run API, all the user-space process provided buffers are either being copied to kernel buffers or they are being mapped in kernel using get_user_pages.
Either way it is wrong because by the time cryptask_routine is executing, it is running in work_queue kernel thread context and not in process context. So, these user-space buffer are not accessible in work-queue Context. In my view, asynchronous support needs to be fixed.
