NPE with wildfly-openssl using OpenSSL 1.1.1a --------------------------------------------- Key: WFLY-11640 URL: https://issues.jboss.org/browse/WFLY-11640 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 15.0.1.Final Environment: OpenSSL 1.1.1a Reporter: Jan Stourac Assignee: Ingo Weiss Priority: Major It is impossible to use {{wildfly-openssl}} binding with OpenSSL 1.1.1a (RHEL8 uses 1.1.1 at the moment but there seems to be same issue). There is an NPE during the ciphersuites initialization: {code} 9:10:58,330 WARNING [org.wildfly.openssl.OpenSSLContextSPI] (MSC service thread 1-3) WFOPENSSL0014 Failed to initialize ciphers: java.lang.NullPointerException at org.wildfly.openssl.CipherSuiteConverter.toJava(CipherSuiteConverter.java:284) at org.wildfly.openssl.OpenSSLContextSPI.getAvailableCipherSuites(OpenSSLContextSPI.java:109) at org.wildfly.openssl.OpenSSLEngine.getSupportedCipherSuites(OpenSSLEngine.java:711) at org.wildfly.openssl.OpenSSLSocket.getSupportedCipherSuites(OpenSSLSocket.java:163) at javax.net.ssl.SSLContextSpi.engineGetSupportedSSLParameters(SSLContextSpi.java:194) at javax.net.ssl.SSLContext.getSupportedSSLParameters(SSLContext.java:436) at org.jboss.as.domain.management.security.SSLContextService.wrapSslContext(SSLContextService.java:116) at org.jboss.as.domain.management.security.SSLContextService.start(SSLContextService.java:102) at org.jboss.msc.service.ServiceControllerImpl$StartTask.startService(ServiceControllerImpl.java:1738) at org.jboss.msc.service.ServiceControllerImpl$StartTask.execute(ServiceControllerImpl.java:1700) at org.jboss.msc.service.ServiceControllerImpl$ControllerTask.run(ServiceControllerImpl.java:1558) at org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1985) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1487) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1378) at java.lang.Thread.run(Thread.java:748) {code} and then there is NPE during the request itself: {code} 19:12:18,417 ERROR [org.xnio.listener] (default I/O-2) XNIO001007: A channel event listener threw an exception: java.lang.NullPointerException at org.wildfly.openssl.CipherSuiteConverter.toJava(CipherSuiteConverter.java:284) at org.wildfly.openssl.OpenSSLEngine.toJavaCipherSuite(OpenSSLEngine.java:1094) at org.wildfly.openssl.OpenSSLEngine.getEnabledCipherSuites(OpenSSLEngine.java:729) at org.wildfly.openssl.OpenSSLContextSPI.getCiphers(OpenSSLContextSPI.java:339) at org.wildfly.openssl.OpenSSLEngine.getEnabledCipherSuites(OpenSSLEngine.java:720) at io.undertow.server.protocol.http.AlpnOpenListener.engineSupportsHTTP2(AlpnOpenListener.java:324) at io.undertow.server.protocol.http.AlpnOpenListener$1.apply(AlpnOpenListener.java:239) at io.undertow.server.protocol.http.AlpnOpenListener$1.apply(AlpnOpenListener.java:235) at io.undertow.server.protocol.http.AlpnOpenListener$SSLConduitUpdater.apply(AlpnOpenListener.java:430) at io.undertow.server.protocol.http.AlpnOpenListener$SSLConduitUpdater.apply(AlpnOpenListener.java:419) at io.undertow.protocols.alpn.DefaultAlpnEngineManager.registerEngine(DefaultAlpnEngineManager.java:31) at io.undertow.protocols.alpn.ALPNManager.registerEngineCallback(ALPNManager.java:80) at io.undertow.server.protocol.http.AlpnOpenListener.handleEvent(AlpnOpenListener.java:235) at io.undertow.server.protocol.http.AlpnOpenListener.handleEvent(AlpnOpenListener.java:64) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:291) at org.xnio.ChannelListeners$10.handleEvent(ChannelListeners.java:286) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.ChannelListeners$DelegatingChannelListener.handleEvent(ChannelListeners.java:1092) at org.xnio.ChannelListeners.invokeChannelListener(ChannelListeners.java:92) at org.xnio.nio.QueuedNioTcpServer$1.run(QueuedNioTcpServer.java:131) at org.xnio.nio.WorkerThread.safeRun(WorkerThread.java:612) at org.xnio.nio.WorkerThread.run(WorkerThread.java:479) {code} Looking briefly into it, the cipher that is trying to be used is *{{TLS_AES_256_GCM_SHA384}}*. It is interesting that this cipher has underscores '_' in its name instead of hyphens '-' as most of the openssl ciphers have. Looks like these were added in the sake of TLSv1.3, [see here|https://github.com/openssl/openssl/commit/fa25763b5528b56b448d64bfba...].
