IPv6ScopeIdMatchUnitTestCase fails if some IPv6 subinterface exists ------------------------------------------------------------------- Key: WFCORE-794 URL: https://issues.jboss.org/browse/WFCORE-794 Project: WildFly Core Issue Type: Bug Components: Test Suite Affects Versions: 2.0.0.Alpha5 Reporter: Petr Kremensky Assignee: Petr Kremensky Fix For: 3.0.0.Alpha1 The test (org.jboss.as.controller.interfacesIPv6ScopeIdMatchUnitTestCase) keeps failing on one of our Solaris boxes with following interfaces: {noformat} /usr/sbin/ifconfig -a ... lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1 inet6 ::1/128 net0: flags=120002000841<UP,RUNNING,MULTICAST,IPv6,PHYSRUNNING> mtu 1500 index 2 inet6 fe80::221:28ff:feb3:20f2/10 net0:1: flags=120002080841<UP,RUNNING,MULTICAST,ADDRCONF,IPv6,PHYSRUNNING> mtu 1500 index 2 inet6 2620:52:0:105f:221:28ff:feb3:20f2/64 net4: flags=120002000840<RUNNING,MULTICAST,IPv6,PHYSRUNNING> mtu 1500 index 3 inet6 ::/0 {noformat} *Error Message* {noformat} expected:</2620:52:0:105f:221:28ff:feb3:20f2%2> but was:<null> {noformat} *Stacktrace* {noformat} java.lang.AssertionError: expected:</2620:52:0:105f:221:28ff:feb3:20f2%2> but was:<null> at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.failNotEquals(Assert.java:743) at org.junit.Assert.assertEquals(Assert.java:118) at org.junit.Assert.assertEquals(Assert.java:144) at org.jboss.as.controller.interfaces.IPv6ScopeIdMatchUnitTestCase.testNonLoopback(IPv6ScopeIdMatchUnitTestCase.java:129) {noformat} Promlem is, that getByName returns null when resolving NetworkInterface by its subinterface name (net0:1 in this case). See following example. {noformat} Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces(); while (interfaces.hasMoreElements()) { NetworkInterface nic = interfaces.nextElement(); Enumeration<NetworkInterface> subInterfaces = nic.getSubInterfaces(); while (subInterfaces.hasMoreElements()) { NetworkInterface subInterface = subInterfaces.nextElement(); System.out.println(subInterface.getName()); System.out.println(NetworkInterface.getByName(subInterface.getName())); } } {noformat} ---- {noformat} em1:0 null {noformat}
