Summary: Server encryption cannot be enabled with the IBM JRE 1.7 Key: CASSANDRA-11405 URL: https://issues.apache.org/jira/browse/CASSANDRA-11405 Project: Cassandra Issue Type: Bug Components: Configuration Environment: Linux, IBM JRE 1.7 Reporter: Guillermo Vega-Toro Fix For: 2.2.6 When enabling server encryption with the IBM JRE (algorithm: IbmX509), an IllegalArgumentException is thrown from the IBM JSSE when the server is started: ERROR 10:04:37,326 Exception encountered during startup java.lang.IllegalArgumentException: SSLv2Hello at com.ibm.jsse2.qb.a(qb.java:50) at com.ibm.jsse2.pb.a(pb.java:101) at com.ibm.jsse2.pb.<init>(pb.java:77) at com.ibm.jsse2.oc.setEnabledProtocols(oc.java:77) at org.apache.cassandra.security.SSLFactory.getServerSocket(SSLFactory.java:64) at org.apache.cassandra.net.MessagingService.getServerSockets(MessagingService.java:425) at org.apache.cassandra.net.MessagingService.listen(MessagingService.java:409) at org.apache.cassandra.service.StorageService.prepareToJoin(StorageService.java:693) at org.apache.cassandra.service.StorageService.initServer(StorageService.java:623) at org.apache.cassandra.service.StorageService.initServer(StorageService.java:515) at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:437) at org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:567) at org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:656) The problem is that the IBM JSSE does not support SSLv2Hello, but this protocol is hard-coded in class org.apache.cassandra.security.SSLFactory: public static final String[] ACCEPTED_PROTOCOLS = new String[] {"SSLv2Hello", "TLSv1", "TLSv1.1", "TLSv1.2"}; public static SSLServerSocket getServerSocket(EncryptionOptions options, InetAddress address, int port) throws IOException { SSLContext ctx = createSSLContext(options, true); SSLServerSocket serverSocket = (SSLServerSocket)ctx.getServerSocketFactory().createServerSocket(); serverSocket.setReuseAddress(true); String[] suits = filterCipherSuites(serverSocket.getSupportedCipherSuites(), options.cipher_suites); serverSocket.setEnabledCipherSuites(suits); serverSocket.setNeedClientAuth(options.require_client_auth); serverSocket.setEnabledProtocols(ACCEPTED_PROTOCOLS); serverSocket.bind(new InetSocketAddress(address, port), 500); return serverSocket; } This ACCEPTED_PROTOCOLS array should not be hard-coded. It should rather read the protocols from configuration, or if the algorithm is IbmX509, simply do not call setEnabledProtocols - with the IBM JSSE, the enabled protocol is controlled by the protocol passed to SSLContext.getInstance. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
