Do not hold lock when IPC call is expected from HAL. C2SurfaceSyncObj is shared lock between framework and HAL. HAL process can have only one thread to handle IPC from HAL to framework. Therefore Holding C2SurfaceSyncObj from HAL during IPC call could trigger deadlock. The exact scenario is as follows. Thread #1:(HAL -> framework IPC) HIDL call onInputBuffersReleased() calls to feedInputBufferIfAvailable(). Since this is using HAL IPC thread, this will block Thread #3. This is waiting for mOuput mutex which is held by Thread #2. Thread #2:(framework) discardBuffer() holds mOutput mutex which blocks Thread #1. But this is waiting for C2SurfaceSyncObj which is held by Thread #3. Thread #3:(HAL) Dtor of C2BufferQueueBlockPoolData is holding C2SurfaceSyncObj, therefore this will block #2. This thread is waiting for HIDL IPC thread to be free in order for 'igbp->cancel()', but HIDL IPC thread is already occupied by Thread #1.
