NdisFOidRequest发送OID请求

我想从FIlter发送一个OID到miniport.可是总是出现蓝屏事件。烦请帮我看看：

NDIS_STATUS
filterCreateNewMACRequest(
    IN NDIS_HANDLE                  FilterModuleContext,
    IN NDIS_OID                     Oid
   )
  /* Routine Description:
      Send OID to underlying driver to create a new MAC 
 Arguments:
     FilterModuleContext - pointer to filter module context
     Oid    -- OID_DOT11_CREATE_MAC
    */
   {
 PMS_FILTER                      pFilter =(PMS_FILTER)FilterModuleContext;
 NDIS_STATUS                     Status = NDIS_STATUS_SUCCESS;
 DOT11_MAC_INFO                InformationBuffer;
 ULONG                           MethodId = 0;
 ULONG                           BytesProcessed;
 DEBUGP(DL_TEST,("==>FilterCreateNEwMACRequest!\n"));
 
 Status = filterDoInternalRequest(pFilter,
                                  NdisRequestMethod,
          Oid,
          (PVOID)&InformationBuffer,
          sizeof(DOT11_MAC_INFO),
          sizeof(DOT11_MAC_INFO),
          MethodId,
          &BytesProcessed); 
 if(Status == NDIS_STATUS_SUCCESS)
    {
     DEBUGP(DL_TEST,("Create new mac successfully, and the length is %u!\n",InformationBufferLength));
  goto Exit;
    }else
 {
 DEBUGP(DL_TEST,("Fail to create new MAC!\n"));
 goto Exit;
 } 
Exit:  
    return Status; 
   }

filterDoInternalRequest的函数体为：

NDIS_STATUS
filterDoInternalRequest(
    IN PMS_FILTER                   FilterModuleContext,
    IN NDIS_REQUEST_TYPE            RequestType,
    IN NDIS_OID                     Oid,
    IN PVOID                        InformationBuffer,
    IN ULONG                        InformationBufferLength,
    IN ULONG                        OutputBufferLength, OPTIONAL
    IN ULONG                        MethodId, OPTIONAL
    OUT PULONG                      pBytesProcessed
    )

{
    FILTER_REQUEST              FilterRequest;
    PNDIS_OID_REQUEST           NdisRequest = &FilterRequest.Request;
    NDIS_STATUS                 Status = NDIS_STATUS_SUCCESS;
    DEBUGP(DL_TEST,("==>filterDoInternalRequest\n"))
    NdisZeroMemory(NdisRequest, sizeof(NDIS_OID_REQUEST));
    NdisInitializeEvent(&FilterRequest.ReqEvent);
    
    NdisRequest->Header.Type = NDIS_OBJECT_TYPE_OID_REQUEST;
    NdisRequest->Header.Revision = NDIS_OID_REQUEST_REVISION_1;
    NdisRequest->Header.Size = sizeof(NDIS_OID_REQUEST);
    NdisRequest->RequestType = RequestType;
    switch (RequestType)
    {
        case NdisRequestQueryInformation:
             NdisRequest->DATA.QUERY_INFORMATION.Oid = Oid;
             NdisRequest->DATA.QUERY_INFORMATION.InformationBuffer =
                                    InformationBuffer;
             NdisRequest->DATA.QUERY_INFORMATION.InformationBufferLength =
                                    InformationBufferLength;
            break;
        case NdisRequestSetInformation:
             NdisRequest->DATA.SET_INFORMATION.Oid = Oid;

             NdisRequest->DATA.METHOD_INFORMATION.MethodId = MethodId;
             NdisRequest->DATA.METHOD_INFORMATION.InformationBuffer =
                                    InformationBuffer;
             NdisRequest->DATA.METHOD_INFORMATION.InputBufferLength =
                                    InformationBufferLength;
             NdisRequest->DATA.METHOD_INFORMATION.OutputBufferLength = OutputBufferLength;
             break;
             
                
        default:
            FILTER_ASSERT(FALSE);
            break;
    }
   /  NdisRequest->RequestId = (PVOID)FILTER_REQUEST_ID;
    
    Status = NdisFOidRequest(FilterModuleContext->FilterHandle,
                            NdisRequest);
    
    if (Status == NDIS_STATUS_PENDING)
    {
        
        NdisWaitEvent(&FilterRequest.ReqEvent, 0);
        Status = FilterRequest.Status;
    }

    if (Status == NDIS_STATUS_SUCCESS)
    {
        if (RequestType == NdisRequestSetInformation)
        {
            *pBytesProcessed = NdisRequest->DATA.SET_INFORMATION.BytesRead;
        }
        if (RequestType == NdisRequestQueryInformation)
        {
            *pBytesProcessed = NdisRequest->DATA.QUERY_INFORMATION.BytesWritten;
        }
        if (RequestType == NdisRequestMethod)
        {

        // The driver below should set the correct value to BytesWritten 
        // or BytesRead. But now, we just truncate the value to InformationBufferLength
        //
        if (RequestType == NdisRequestMethod)
        {
            if (*pBytesProcessed > OutputBufferLength)
            {
                *pBytesProcessed = OutputBufferLength;
            }
        }
        else
        {
            
            if (*pBytesProcessed > InformationBufferLength)
            {
                *pBytesProcessed = InformationBufferLength;
            }
        }
    } 

    return (Status);
}

在函数filterDoInternalRequest中，每次执行到NdisFOidRequest()就出现蓝屏了。不知道哪里不对？

锁的问题，搞定
