As a result, if we use\nget_random_bytes() to generate random bytes in the randbuf, the\nnull pointer dereference bug will happen.\n\nIn order to prevent allocation failure, this patch adds a separate\nfunction using buffer on kernel stack to generate random bytes in\nthe randbuf, which could prevent the kernel stack from overflow."
