RFC 6347 : 4.2.8. Establishing New Associations with Existing Parameters

Hi,

Does openSSL implement the section "4.2.8. Establishing New Associations with Existing Parameters" in RFC 6347

I tried to test the feature with "openssl-1.1.1c" but couldn't simulate the same.

Some details about my sample test:

Client:

1. Initiate a connection request for DTLS 1.2(target on a particular IP/port)
2. Then close the DTLS connection(abruptly and not sending SSL shutdown message)
3. Try to initiate a second connection request to same target on the same initial IP/port 

Server:

1. Accept the DTLS connection request (cookie exchange mechanism enabled)
2. Then call SSL_read to read the application data over DTLS
3. But it will get a connection request from client side(Basically client hello)

Observation:

1. The client hangs in second handshake just retransmitting client hellos
2. The server just hangs in SSL_read(probably dropping the client hello messages)

Thanks in advance for the help!
