      Description

      We somehow get a received > data_size situation, so we overrun the data buffer.
      The reason is that schan_imp_recv's check for ROS_SCHAN_IS_BLOCKING is broken – it also triggers for error codes such as MBEDTLS_ERR_SSL_WANT_READ or MBEDTLS_ERR_SSL_WANT_WRITE.

      Looking at the function, the MBEDTLS_ERR_SSL_PEER_CLOSE_NOTIFY also seems broken – it should probably return a length of 0.
