Subject SV: retrieve SSLSession to check the client certificate validity
Date Tue, 23 Jun 2009 14:01:31 GMT

I had the same issue, both sessionCreated and sessionOpened are called before the ssl handshake
is complete - this is handled by the filter as data is received after the session is opened.

 I resolved it by blocking :p in the sessionOpened call back, waiting for some timeout. Not
sure if it will work for you though - depends on your threading model.

public void sessionOpened(IoSession session) throws Exception {
        IoFilter filter = session.getFilterChain().get(this.sslFilterName);
        if (isUseTLS() && filter instanceof SslFilter) {
            logger.debug("Waiting for client {0} to initiate handshake", session);
            Timeout clientMustInitateHandshake = new Timeout(this.HANDSHAKE_TIMEOUT_MS);
            while (null == session.getAttribute(SslFilter.SSL_SESSION) && !clientMustInitateHandshake.isTimedout())
            SSLSession sslSession = (SSLSession) session.getAttribute(SslFilter.SSL_SESSION);

            if (null == sslSession) {
                logger.warning("The client {1} did not initiate the TLS handshake within timeout
{0}", null,
                        this.HANDSHAKE_TIMEOUT_MS, session);
                throw new javax.net.ssl.SSLHandshakeException(
                        "Client did not initiate TLS handshake in a timely fashion. SSL handshake
            } else {

                Certificate[] certificates = sslSession.getPeerCertificates(); 
... Snip ...

Hope this helps.

Thanks for the reply. But this does not work either :(.
Any other suggestion?

Hi Cédric,

in the sessionCreated() method of the handler, doing this:

Not sure that the SSLSession is injected into the session's attribute when the sessionCreated
event is received. Can you check the very same but on the sessionOpened event ?
