Доброе время суток.
Пишу следующий код:
NDIS_Filter.c
#include <ntstatus.h>
#include <ntddk.h>
#include <pfhook.h>
//#include <ntoskrnl.h>
TCHAR drvsmbl[]=TEXT("\\Device\\IPFILTERDRIVER");
NTSTATUS Status=STATUS_SUCCESS;
PFILE_OBJECT fileobject=NULL;
PDEVICE_OBJECT devobject=NULL;
PF_SET_EXTENSION_HOOK_INFO hook_info
IO_STATUS_BLOCK isb;
PIRP myirp=NULL;
VOID Unload(IN PDRIVER_OBJECT DriverObject);
PF_FORWARD_ACTION hook_fn(IN unsigned char *PacketHeader,IN unsigned char *Packet,
IN unsigned int PacketLength, IN unsigned int RecvInterfaceIndex,
IN unsigned int SendInterfaceIndex, IN IPAddr RecvLinkNextHop,
IN IPAddr SendLinkNextHop};
//===================================================================================
NTSTATUS DriverEntry(IN PDRIVER_OBJECT DriverObject,IN PUNICODE_STRING RegistryPath)
{
Status=Set_Hook(hook_fn);
if(Status!=STATUS_SUCCESS)
return Status;
DriverObject->DriverUnload=Unload;
return Status;
}
//===================================================================================
VOID Unload(IN PDRIVER_OBJECT DriverObject)
{
Set_Hook(0);
}
//===================================================================================
NTSTATUS Set_Hook(PacketFilterExtensionPtr hook_fn)
{
NTSTATUS status=IoGetDeviceObjectPointer(drvsmbl,STANDART_RIGHTS_ALL,&fileopject,&devobject);
if(status!=STATUS_SUCCESS)
return status;
hook_info.ExtensionPointer=hook_fn;
myirp=IoBuildDeviceIoControlRequest(IOCTL_PF_SET_EXTENSION_POINTER,devobject,&hook_info,
sizeof(hook_info),NULL,0,FALSE,NULL,&isb);
status=IoCallDriver(devobject,myirp);
return status;
}
//===================================================================================
PF_FORWARD_ACTION hook_fn(IN unsigned char *PacketHeader,IN unsigned char *Packet,
IN unsigned int PacketLength, IN unsigned int RecvInterfaceIndex,
IN unsigned int SendInterfaceIndex, IN IPAddr RecvLinkNextHop,
IN IPAddr SendLinkNextHop}
{
return PF_DROP;
}
//===================================================================================
И в ответ на BUILD
Получаю:

В чем я косячу?
В чем проблева в pfhook.h?
