Hi, I am using OpenSSL-1.0.0d (release) + all cumulative bug fixes + DTLS Heartbeat feature patch on Windows.
A DTLS server (non-blocking) using DTLSv1_Listen having a UDP socket with SO_REUSEADDR is unable to accept a second client connection when it is already accepted a client connection and serving it. Details: Server Client 1 State DTLSv1_Listen Handshake complete Established Client 2 State Keeps sending CLIENT HELLO but Server never responds with HelloVerify request and select never gets triggered on the listen fd (used by DTLSv1_listen) As per some of the windows documents for connect, see excerpt below: http://msdn.microsoft.com/en-us/library/ms737625%28v=vs.85%29.aspx "For a connectionless socket (for example, type SOCK_DGRAM), the operation performed by connect is merely to establish a default destination address that can be used on subsequent send/ WSASend and recv/ WSARecv calls. Any datagrams received from an address other than the destination address specified will be discarded." So it appears that once a socket is connected to a client, it will no longer be used for accepting second client. It has been observed, that when the first client connection is released (terminated) a new client connection is accepted. This is not a problem on Linux. Is there any workarounds or special handling for windows ?
