CVE-2021-47511

The period size calculation in OSS layer may receive a negative value as an error, but the code there assumes only the positive values and handle them with size_t. Due to that, a too big value may be passed to the lower layers.

This patch changes the code to handle with ssize_t and adds the proper error checks appropriately.
