Untrusted SSL certificate used for client authentication leads to Broken pipe IOException intermittently --------------------------------------------------------------------------------------------------------- Key: WFCORE-3171 URL: https://issues.jboss.org/browse/WFCORE-3171 Project: WildFly Core Issue Type: Bug Components: Security, Test Suite Affects Versions: 3.0.0.Beta30 Reporter: Jan Kalina Assignee: Jan Kalina Priority: Blocker Untrusted SSL certificate used for authentication leads to "IOException: Broken pipe" intermittently. *Description of problem:* ExternalMgmtSaslTestCase from wf-core fails intermittently (80%) on pure-ipv6 RHEL6 machines. The test configures two-way-SSL and try to use untrusted client certificate. IOException comes and the test checks if the cause is an SSLException (which is expected), but in some cases "IOException: Broken pipe" comes as the cause instead. *How reproducible:* 80% on pure-ipv6 RHEL6 machines *Steps to Reproduce:* {code} cd testsuite/elytron export PROXY_PARAMS="-DproxySet=true -DproxyHost=proxy-01-ipv6.mw.lab.eng.bos.redhat.com -DproxyPort=3128 -Dhttp.proxyHost=proxy-01-ipv6.mw.lab.eng.bos.redhat.com -Dhttp.proxyPort=3128 -Dhttps.proxyHost=proxy-01-ipv6.mw.lab.eng.bos.redhat.com -Dhttps.proxyPort=3128" mvn install -B -fae -llr -Dipv6 $PROXY_PARAMS -Dts.timeout.factor=300 -Dtimeout.factor=300 -Dtest=ExternalMgmtSaslTestCase {code} Failing test is *testUntrustedCertFails*, but looks like not reproducible without running whole testcase. *Actual results:* StackTrace: {noformat} 17:03:12 java.lang.AssertionError: SSLException was expected as the second cause when certificate authentication fails 17:03:12 Expected: is an instance of javax.net.ssl.SSLException 17:03:12 but: <java.io.IOException: Broken pipe> is a java.io.IOException 17:03:12 at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20) 17:03:12 at org.junit.Assert.assertThat(Assert.java:956) 17:03:12 at org.wildfly.test.integration.elytron.sasl.mgmt.ExternalMgmtSaslTestCase.assertCertAuthenticationFails(ExternalMgmtSaslTestCase.java:216) 17:03:12 at org.wildfly.test.integration.elytron.sasl.mgmt.ExternalMgmtSaslTestCase.lambda$testUntrustedCertFails$3(ExternalMgmtSaslTestCase.java:201) {noformat} Standard output: {noformat} [0m15:03:10,908 INFO [org.jboss.as] (MSC service thread 1-2) WFLYSRV0050: WildFly Core 3.0.0.Beta30-redhat-1 "Kenny" stopped in 39ms [0m[0m15:03:10,910 INFO [org.jboss.as] (MSC service thread 1-2) WFLYSRV0049: WildFly Core 3.0.0.Beta30-redhat-1 "Kenny" starting [0m[0m15:03:11,057 INFO [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0039: Creating http management service using socket-binding (management-http) [0m[33m15:03:11,132 WARN [org.jboss.as.domain.http.api.undertow] (MSC service thread 1-1) WFLYDMHTTP0003: Unable to load console module for slot main, disabling console [0m[0m15:03:11,146 INFO [org.jboss.as.patching] (MSC service thread 1-4) WFLYPAT0050: WildFly cumulative patch ID is: base, one-off patches include: none [0m[33m15:03:11,147 WARN [org.jboss.as.domain.management.security] (MSC service thread 1-4) WFLYDM0111: Keystore /mnt/hudson_workspace/eap-7x-as-testsuite-test-core-rhel-ipv6-broken-pipe/7a0f50f2/testsuite/elytron/target/wildfly-core/standalone/configuration/application.keystore not found, it will be auto generated on first use with a self signed certificate for host localhost [0m[0m15:03:11,252 INFO [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0212: Resuming server [0m[0m15:03:11,256 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0060: Http management interface listening on http://[::1]:9990/management [0m[0m15:03:11,256 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0051: Admin console listening on http://[::1]:9990 [0m[0m15:03:11,260 INFO [org.jboss.as] (Controller Boot Thread) WFLYSRV0025: WildFly Core 3.0.0.Beta30-redhat-1 "Kenny" started in 345ms - Started 83 of 86 services (17 services are lazy, passive or on-demand) [0m[0m15:03:11,369 INFO [org.jboss.as.server] (management-handler-thread - 3) WFLYSRV0236: Suspending server with no timeout.
