我认为内核对象类型是您所追求的。使用以下命令在内核调试器或 livekd 中签出
0: kd> !object \ObjectTypes
Object: ffffe589f9c17aa0 Type: (ffffb28572cd3820) Directory
ObjectHeader: ffffe589f9c17a70 (new version)
HandleCount: 0 PointerCount: 68
Directory Object: ffffe589f9c14a60 Name: ObjectTypes
Hash Address Type Name
---- ------- ---- ----
00 ffffb28572d7e180 Type TmTm
01 ffffb28572d76310 Type Desktop
ffffb28572c3e680 Type Process
02 ffffb28572d53ad0 Type EnergyTracker
ffffb28572d5cbb0 Type RegistryTransaction
03 ffffb28572cccc60 Type DebugObject
04 ffffb28575682520 Type VRegConfigurationContext
ffffb28572ccc440 Type TpWorkerFactory
05 ffffb28572d6da20 Type Adapter
ffffb28572ccfc40 Type Token
06 ffffb2857562ebb0 Type DxgkSharedResource
07 ffffb28572ccb560 Type PsSiloContextPaged
....
然后你可以转储对象头
0: kd> dt nt!_OBJECT_TYPE ffffb28572d68e80
+0x000 TypeList : _LIST_ENTRY [ 0xffffb285`72d68e80 - 0xffffb285`72d68e80 ]
+0x010 Name : _UNICODE_STRING "Section"
+0x020 DefaultObject : 0xfffff801`a03c4680 Void
**+0x028 Index : 0x29 ')'**
+0x02c TotalNumberOfObjects : 0x4943
+0x030 TotalNumberOfHandles : 0xf50
+0x034 HighWaterNumberOfObjects : 0x4ccc
+0x038 HighWaterNumberOfHandles : 0x10c3
+0x040 TypeInfo : _OBJECT_TYPE_INITIALIZER
+0x0b8 TypeLock : _EX_PUSH_LOCK
+0x0c0 Key : 0x74636553
+0x0c8 CallbackList : _LIST_ENTRY [ 0xffffb285`72d68f48 - 0xffffb285`72d68f48 ]
Index 字段应与相应的 ETW 事件相关。我不确定这个索引在 Windows 版本之间是否保持不变,但我认为不是。
Process Hacker(更好的进程浏览器)使用以下方法格式化对象类型:
static VOID PhpDumpObjectInfo(
_In_ PPH_OBJECT_HEADER ObjectHeader
)
{
PVOID object;
PPH_OBJECT_TYPE objectType;
object = PhObjectHeaderToObject(ObjectHeader);
objectType = PhGetObjectType(object);
__try
{
wprintf(L"Type: %s\n", objectType->Name);
wprintf(L"Reference count: %d\n", ObjectHeader->RefCount);
wprintf(L"Flags: %x\n", ObjectHeader->Flags);
if (objectType == PhObjectTypeObject)
{
wprintf(L"Name: %s\n", ((PPH_OBJECT_TYPE)object)->Name);
wprintf(L"Number of objects: %u\n", ((PPH_OBJECT_TYPE)object)->NumberOfObjects);
wprintf(L"Flags: %u\n", ((PPH_OBJECT_TYPE)object)->Flags);
wprintf(L"Type index: %u\n", ((PPH_OBJECT_TYPE)object)->TypeIndex);
wprintf(L"Free list count: %u\n", ((PPH_OBJECT_TYPE)object)->FreeList.Count);
}
else if (objectType == PhStringType)
{
wprintf(L"%s\n", ((PPH_STRING)object)->Buffer);
}
这应该会给你一些指示下一步该往哪里看。
