'HookedDeviceControl': 未声明的标识符

Question

我在编译这段代码时收到 'HookedDeviceControl': undeclared identifier 错误。 (InterlockedExchange((PLONG)&pDrv_tcpip->MajorFunction[IRP_MJ_DEVICE_CONTROL],(LONG)HookedDeviceControl);)“HookedDeviceControl”函数是否需要在其中包含特定代码？我需要任何特定的库或导入吗？我不完全确定为什么在有 HookedDeviceControl 函数时说它无法识别

#include <wdm.h>

VOID Unload_Driver() {
    DbgPrint("Driver Successfully Unloaded");
}

NTSTATUS DriverEntry(IN PDRIVER_OBJECT DriverObject, IN PUNICODE_STRING RegistryPath) // this is main
{
    UNREFERENCED_PARAMETER(RegistryPath);
    UNREFERENCED_PARAMETER(DriverObject);
    //HookedMjCreate();
    DriverObject->DriverUnload = Unload_Driver;
}

PFILE_OBJECT pFile_tcp;
PDEVICE_OBJECT pDev_tcp;
PDRIVER_OBJECT pDrv_tcpip;
typedef NTSTATUS(*OLDIRPMJDEVICECONTROL)(IN PDEVICE_OBJECT, IN PIRP);
OLDIRPMJDEVICECONTROL OldIrpMjDeviceControl;

NTSTATUS InstallTCPDriverHook(IN ACCESS_MASK DesiredAccess)
{
    NTSTATUS ntStatus;
    UNICODE_STRING deviceTCPUnicodeString;
    WCHAR deviceTCPNameBuffer[] = L"\Device\Tcp";
    pFile_tcp = NULL;
    pDev_tcp = NULL;
    ntStatus = IoGetDeviceObjectPointer(L"\Device\Tcp", FILE_READ_DATA, &pFile_tcp, &pDev_tcp);
    RtlInitUnicodeString(&deviceTCPUnicodeString,
        deviceTCPNameBuffer);
    ntStatus = IoGetDeviceObjectPointer(&deviceTCPUnicodeString,
        FILE_READ_DATA, &pFile_tcp,
        &pDev_tcp);
    if (!NT_SUCCESS(ntStatus))
        return ntStatus;
    pDrv_tcpip = pDev_tcp->DriverObject;
    OldIrpMjDeviceControl = pDrv_tcpip->
        MajorFunction[IRP_MJ_DEVICE_CONTROL];
    if (OldIrpMjDeviceControl)
        InterlockedExchange((PLONG)&pDrv_tcpip->MajorFunction[IRP_MJ_DEVICE_CONTROL],(LONG)HookedDeviceControl);
    return STATUS_SUCCESS;
}



NTSTATUS HookedDeviceControl(IN PDEVICE_OBJECT DeviceObject,IN PIRP Irp)
{

}```

Answer 1

您需要 declare/define 函数 HookedDeviceControl 才能调用它或将其作为参数传递。所以选择之一是在 InstallTCPDriverHook:

之前定义 HookedDeviceControl

NTSTATUS HookedDeviceControl(IN PDEVICE_OBJECT DeviceObject,IN PIRP Irp)
{
   ...
}
NTSTATUS InstallTCPDriverHook(IN ACCESS_MASK DesiredAccess)
{
  ...
}

'HookedDeviceControl': 未声明的标识符

'HookedDeviceControl': undeclared identifier
