Hi Susan, 1. Do not disable polling for NetVC. - SSLNetVC read data into rBIO and call SSL_accept(). - We have to fill the rBIO by polling READ event on NetVC. - Add a new `EventIO trigger_ep;` for SSLNetVC.
2. Do not share the EventIO with socket fd and openssl wait fd 3. Handle SSL_ERROR_WANT_ASYNC within switch(ssl_error) statement - Consider it is a kind of recoverable ssl error - Set up the epoll entry for the waitfd 4. Clean up the epoll entry only on handshake done - Now, it is only support ASYNC mode on ssl handshake. - Next, we can expand the ASYNC mode on ssl data send & receive Please find the details in the attached patch file. -- - Oknet Xu
