FIX: WinMgmt Halts If You Get a WMI Object from One Namespace and Put it in Another Namespace (231226)

MORE INFORMATION

Steps to Reproduce Behavior

1. Compile the following mof. This mof creates two namespaces, "namespace1" and "namespace2". Namespace2 is a child of namespace1. Both classes have an identical class named "test". An instance of test is created in namespace1:

   #pragma namespace("\\\\.\\ROOT")
   
   instance of __namespace
   {
   	name = "namespace1";
   };
   
   #pragma namespace("\\\\.\\ROOT\\namespace1")
   
   class test
   {
   	[key] string mykey;
   };
   
   instance of test
   {
   	mykey = "a";
   };
   
   instance of __namespace
   {
   	name = "namespace2";
   };
   
   #pragma namespace("\\\\.\\ROOT\\namespace1\\namespace2")
   
   class test
   {
   	[key] string mykey;
   
   };

2. Run the following code in a C++ WMI client program. Error checking has been omitted for brevity:

   BSTR pNamespace1 = SysAllocString(L"root\\namespace1");
   BSTR pNamespace2 = SysAllocString(L"namespace2");
   IWbemServices *pIWbemServices1 = NULL;
   IWbemServices *pIWbemServices2 = NULL;
   IWbemLocator *pIWbemLocator = NULL;
   
   CoCreateInstance(CLSID_WbemLocator,NULL,CLSCTX_INPROC_SERVER,IID_IWbemLocator,(LPVOID *) &pIWbemLocator);
   
   // Connect to the first namespace
   pIWbemLocator->ConnectServer(pNamespace1,NULL,NULL,0L,0L,NULL,NULL,&pIWbemServices1);
   // Connect to the second namespace
   pIWbemServices1->OpenNamespace(pNamespace2,0,0,&pIWbemServices2,0);
   
   // Retrieve the object from the first namespace
   IWbemClassObject *pObject = NULL;
   BSTR pObjectName = SysAllocString(L"test.mykey=\"a\"");
   pIWbemServices1->GetObject(pObjectName,0L,NULL,&pObject,NULL);
   <BR/>
   // Put the object into the second namespace. This will cause WMI 1.1 WinMgmt to crash
   pIWbemServices2->PutInstance(pObject,0,0,0);
