Hi Emmanuel,
Same code is working fine with 2.0.21, There is no deadlock, we have not
done any code changes.
To make it compatible with 2.2.1 we did some https implementation changes
to our custom SSL filter.
Last time I raised my concern on removing PEER_ADDRESS(in 2.2.1) for
passing SNI_HOST_NAME during SSL handshake. Mina core 2.0.21 has some
security vulnerabilities so we tested with 2.0.23, that time your support
team suggested us to migrate to latest mina version 2.2.1, With this we
stuck with dead lock,I am sure after changing Https implementation we are
facing this issue,Here is the code we used in CustomSSLFilter for passing
SNI hostname.
* 2.0.21 implementation:*
public class CustomSslFilter extends SslFilter
{
public CustomSslFilter(SSLContext sslContext) {
super(sslContext);
LOGGER.info("Apache mina 2.0.X https implementation...");
}
public void onPreAdd(IoFilterChain parent, String name,
NextFilter nextFilter) throws SSLException {
// Check that we don't have a SSL filter already present in the
chain
if (parent.contains(SslFilter.class)) {
String msg = "Only one SSL filter is permitted in a chain.";
LOGGER.error(msg);
throw new IllegalStateException(msg);
}
IoSession session = parent.getSession();
Provider provider =
(Provider)session.getAttribute(G10MinaClient.PROVIDER_KEY);
* //Passing SNI hostname during handshake *
InetSocketAddress probeAddress =
InetSocketAddress.createUnresolved(SNIHostNames.DELIVERY_POINT.getHostName(),Integer.parseInt(provider.getProbe().getPortNumber()));
* session.setAttribute(PEER_ADDRESS, probeAddress);*
super.onPreAdd(parent, name, nextFilter);
}
}
* 2.2.1 implementation:*
public class CustomSslFilter extends SslFilter
{
public CustomSslFilter(SSLContext sslContext) {
super(sslContext);
LOGGER.info("Apache mina 2.2.3 https implementation...");
}
protected SSLEngine createEngine(IoSession session, InetSocketAddress addr)
{
Provider provider =
(Provider)session.getAttribute(G10MinaClient.PROVIDER_KEY);
*//Passing SNI hostname during handshake *
InetSocketAddress peer =
InetSocketAddress.createUnresolved(SNIHostNames.DELIVERY_POINT.getHostName(),Integer.parseInt(provider.getProbe().getPortNumber()));
SSLEngine sslEngine = (addr != null) ?
sslContext.createSSLEngine(peer.getHostString(), peer.getPort())
: sslContext.createSSLEngine();
if (wantClientAuth) {
sslEngine.setWantClientAuth(true);
}
if (needClientAuth) {
sslEngine.setNeedClientAuth(true);
}
if (enabledCipherSuites != null) {
sslEngine.setEnabledCipherSuites(enabledCipherSuites);
}
if (enabledProtocols != null) {
sslEngine.setEnabledProtocols(enabledProtocols);
}
sslEngine.setUseClientMode(!session.isServer());
if (session.getAttribute(G10MinaClient.SESSION_ID_KEY) !=null ) {
LOGGER.info(session.getAttribute(G10MinaClient.SESSION_ID_KEY) +
" Adding the SSL Filter to the chain for " +
provider.getProbeDisplayName());
}
else {
LOGGER.info("Adding the SSL Filter to the chain for " +
provider.getProbeDisplayName());
}
return sslEngine;
}
}
I will appreciate your help in advance.
