misc: fastrpc: take fl->lock when moving mmaps on interrupted invoke
In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: take fl->lock when moving mmaps on interrupted invoke When an invoke is interrupted by a signal, wait_for_completion_interruptible() returns -ERESTARTSYS and fastrpc_internal_invoke() moves every buffer from fl->mmaps onto cctx->invoke_interrupted_mmaps. This list_del()/list_add_tail() walk runs without holding fl->lock, the lock that serialises fl->mmaps in fastrpc_req_mmap() and fastrpc_req_munmap() everywhere else. Take fl->lock around the move, matching every other fl->mmaps accessor.
