驅動開發：內核封裝TDI網路通信介面

在上一篇文章《驅動開發：內核封裝WSK網路通信介面》中，LyShark已經帶大家看過了如何通過WSK介面實作套接字通信，但WSK實作的通信是內核與內核模塊之間的，而如果需要內核與應用層之間通信則使用TDK會更好一些因為它更接近應用層，本章將使用TDK實作，TDI全稱傳輸驅動介面，其主要負責連接Socket和協議驅動，用于實作訪問傳輸層的功能，該介面比NDIS更接近于應用層，在早期Win系統中常用于實作過濾防火墻，同樣經過封裝后也可實作通信功能，本章將運用TDI介面實作驅動與應用層之間傳輸字串，結構體，多執行緒收發等技術，

• TDI傳輸字串
• TDI多執行緒收發
• TDI傳數結構實作認證

TDI 傳輸字串: 服務端在應用層偵聽，客戶端是驅動程式，驅動程式加載后自動連接應用層并發送訊息，

首先來看應用層(服務端)代碼，具體我就不說了，來看教程的都是有基礎的，

#define _CRT_SECURE_NO_WARNINGS
#include <iostream>  
#include <winsock2.h>  

#pragma comment(lib,"ws2_32.lib")
#define PORT 8888 

int main(int argc, char *argv[])
{
  printf("hello lyshark.com \n");
  WSADATA WSAData;
  SOCKET sock, msgsock;
  struct sockaddr_in ServerAddr;

  if (WSAStartup(MAKEWORD(2, 0), &WSAData) != SOCKET_ERROR)
  {
    ServerAddr.sin_family = AF_INET;
    ServerAddr.sin_port = htons(PORT);
    ServerAddr.sin_addr.s_addr = INADDR_ANY;

    sock = socket(AF_INET, SOCK_STREAM, 0);
    int BindRet = bind(sock, (LPSOCKADDR)&ServerAddr, sizeof(ServerAddr));
    int LinsRet = listen(sock, 10);
  }

  while (1)
  {
    char buf[1024] = { 0 };
    msgsock = accept(sock, (LPSOCKADDR)0, (int *)0);
    memset(buf, 0, sizeof(buf));

    recv(msgsock, buf, 1024, 0);
    printf("內核回傳: %s \n", buf);

    char send_buffer[1024] = { 0 };
    memset(send_buffer, 0, 1024);
    strcpy(send_buffer, "Hi,R0 !");
    send(msgsock, send_buffer, strlen(send_buffer), 0);
    closesocket(msgsock);
  }
  closesocket(sock);
  WSACleanup();
  return 0;
}

再來是驅動層代碼，如下所示；

// 署名權
// right to sign one's name on a piece of work
// PowerBy: LyShark
// Email: [email protected]

#include "MyTDI.hpp"

// 發送接收資料
NTSTATUS SendOnRecv()
{
  NTSTATUS status = STATUS_SUCCESS;
  HANDLE hTdiAddress = NULL;
  HANDLE hTdiEndPoint = NULL;
  PDEVICE_OBJECT pTdiAddressDevObj = NULL;
  PFILE_OBJECT pTdiEndPointFileObject = NULL;
  LONG pServerIp[4] = { 127, 0, 0, 1 };
  LONG lServerPort = 8888;
  UCHAR szSendData[] = "hello lyshark";
  ULONG ulSendDataLength = 1 + strlen(szSendData);
  HANDLE hThread = NULL;

  // TDI初始化
  status = TdiOpen(&pTdiAddressDevObj, &pTdiEndPointFileObject, &hTdiAddress, &hTdiEndPoint);
  if (!NT_SUCCESS(status))
  {
    return STATUS_SUCCESS;
  }

  // TDI TCP連接服務器
  status = TdiConnection(pTdiAddressDevObj, pTdiEndPointFileObject, pServerIp, lServerPort);
  if (!NT_SUCCESS(status))
  {
    return STATUS_SUCCESS;
  }

  // TDI TCP發送資訊
  status = TdiSend(pTdiAddressDevObj, pTdiEndPointFileObject, szSendData, ulSendDataLength);
  if (!NT_SUCCESS(status))
  {
    return STATUS_SUCCESS;
  }
  DbgPrint("發送: %s\n", szSendData);

  // 創建接收資訊多執行緒, 回圈接收資訊

  char szRecvData[1024] = { 0 };
  ULONG ulRecvDataLenngth = 1024;
  RtlZeroMemory(szRecvData, ulRecvDataLenngth);

  // TDI TCP接收資訊
  do
  {
    ulRecvDataLenngth = TdiRecv(pTdiAddressDevObj, pTdiEndPointFileObject, szRecvData, ulRecvDataLenngth);
    if (0 < ulRecvDataLenngth)
    {
      DbgPrint("接收資料: %s\n", szRecvData);
      break;;
    }

  } while (TRUE);

  // 釋放
  TdiClose(pTdiEndPointFileObject, hTdiAddress, hTdiEndPoint);
  return STATUS_SUCCESS;
}

VOID UnDriver(PDRIVER_OBJECT driver)
{
  DbgPrint("驅動卸載成功 \n");
}

NTSTATUS DriverEntry(IN PDRIVER_OBJECT Driver, PUNICODE_STRING RegistryPath)
{
  for (int x = 0; x < 10; x++)
  {
    SendOnRecv();
  }

  DbgPrint("驅動加載成功 \n");
  Driver->DriverUnload = UnDriver;
  return STATUS_SUCCESS;
}

首先運行應用層開啟服務端偵聽，然后運行驅動程式，會輸出如下資訊；

TDI 多執行緒收發包: 實作驅動內部發送資料包后開啟一個執行緒用于等待應用層回傳并輸出結果，多執行緒收發在發送資料包后需要創建新的執行緒等待接收，

首先是服務端代碼，

#define _CRT_SECURE_NO_WARNINGS
#include <iostream>  
#include <winsock2.h>  

#pragma comment(lib,"ws2_32.lib")
#define PORT 8888 

int main(int argc, char *argv[])
{
	printf("hello lyshark.com \n");
	WSADATA WSAData;
	SOCKET sock, msgsock;
	struct sockaddr_in ServerAddr;

	if (WSAStartup(MAKEWORD(2, 0), &WSAData) != SOCKET_ERROR)
	{
		ServerAddr.sin_family = AF_INET;
		ServerAddr.sin_port = htons(PORT);
		ServerAddr.sin_addr.s_addr = INADDR_ANY;

		sock = socket(AF_INET, SOCK_STREAM, 0);
		int BindRet = bind(sock, (LPSOCKADDR)&ServerAddr, sizeof(ServerAddr));
		int LinsRet = listen(sock, 10);
	}

	while (1)
	{
		char buf[1024] = { 0 };
		msgsock = accept(sock, (LPSOCKADDR)0, (int *)0);
		memset(buf, 0, sizeof(buf));

		recv(msgsock, buf, 1024, 0);
		printf("內核回傳: %s \n", buf);

		char send_buffer[1024] = { 0 };
		memset(send_buffer, 0, 1024);
		strcpy(send_buffer, "Hi,R0 !");
		send(msgsock, send_buffer, strlen(send_buffer), 0);
		closesocket(msgsock);
	}
	closesocket(sock);
	WSACleanup();
	return 0;
}

驅動程式代碼如下，RecvThreadProc主要負責資料接收，SendThreadData負責資料發送，

// 署名權

#include "LySocket.hpp"

typedef struct _MY_DATA
{
	PDEVICE_OBJECT pTdiAddressDevObj;
	PFILE_OBJECT pTdiEndPointFileObject;
	HANDLE hTdiAddress;
	HANDLE hTdiEndPoint;
}MY_DATA, *PMY_DATA;

// 接收資訊多執行緒
VOID RecvThreadProc(_In_ PVOID StartContext)
{
	PMY_DATA pMyData = https://www.cnblogs.com/LyShark/p/(PMY_DATA)StartContext;
	NTSTATUS status = STATUS_SUCCESS;
	char szRecvData[1024] = { 0 };
	ULONG ulRecvDataLenngth = 1024;
	RtlZeroMemory(szRecvData, ulRecvDataLenngth);

	// TDI TCP接收資訊
	do
	{
		ulRecvDataLenngth = TdiRecv(pMyData->pTdiAddressDevObj, pMyData->pTdiEndPointFileObject, szRecvData, ulRecvDataLenngth);
		if (0 < ulRecvDataLenngth)
		{
			DbgPrint("執行緒句柄:%x --> 接收資料包: %s\n", pMyData->hTdiEndPoint, szRecvData);
			break;;
		}

	} while (TRUE);

	// 釋放
	TdiClose(pMyData->pTdiEndPointFileObject, pMyData->hTdiAddress, pMyData->hTdiEndPoint);
	ExFreePool(pMyData);
}

// 多執行緒發送
NTSTATUS SendThreadData()
{
	NTSTATUS status = STATUS_SUCCESS;
	HANDLE hTdiAddress = NULL;
	HANDLE hTdiEndPoint = NULL;
	PDEVICE_OBJECT pTdiAddressDevObj = NULL;
	PFILE_OBJECT pTdiEndPointFileObject = NULL;
	LONG pServerIp[4] = { 127, 0, 0, 1 };
	LONG lServerPort = 8888;
	UCHAR szSendData[] = "hello lyshark";
	ULONG ulSendDataLength = 1 + strlen(szSendData);
	HANDLE hThread = NULL;

	// TDI初始化
	status = TdiOpen(&pTdiAddressDevObj, &pTdiEndPointFileObject, &hTdiAddress, &hTdiEndPoint);
	if (!NT_SUCCESS(status))
	{
		return STATUS_SUCCESS;
	}

	// TDI TCP連接服務器
	status = TdiConnection(pTdiAddressDevObj, pTdiEndPointFileObject, pServerIp, lServerPort);
	if (!NT_SUCCESS(status))
	{
		return STATUS_SUCCESS;
	}

	// TDI TCP發送資訊
	status = TdiSend(pTdiAddressDevObj, pTdiEndPointFileObject, szSendData, ulSendDataLength);
	if (!NT_SUCCESS(status))
	{
		return STATUS_SUCCESS;
	}
	DbgPrint("發送 %s\n", szSendData);

	// 創建接收資訊多執行緒, 回圈接收資訊
	PMY_DATA pMyData = https://www.cnblogs.com/LyShark/p/ExAllocatePool(NonPagedPool, sizeof(MY_DATA));
	pMyData->pTdiAddressDevObj = pTdiAddressDevObj;
	pMyData->pTdiEndPointFileObject = pTdiEndPointFileObject;
	pMyData->hTdiAddress = hTdiAddress;
	pMyData->hTdiEndPoint = hTdiEndPoint;

	PsCreateSystemThread(&hThread, 0, NULL, NtCurrentProcess(), NULL, RecvThreadProc, pMyData);
}

VOID UnDriver(PDRIVER_OBJECT driver)
{
	DbgPrint("驅動卸載成功 \n");
}

NTSTATUS DriverEntry(IN PDRIVER_OBJECT Driver, PUNICODE_STRING RegistryPath)
{
	DbgPrint("hello lyshark.com \n");

	for (int x = 0; x < 10; x++)
	{
		SendThreadData();
	}
	Driver->DriverUnload = UnDriver;
	return STATUS_SUCCESS;
}

運行應用層服務端等待偵聽，運行驅動程式輸出如下效果；

TDI 傳數結構實作認證: 驅動內部發送結構體給應用層，應用層驗證結構體成員，此功能可實作對驅動程式的控制機制，例如是否允許驅動加載卸載等，通常用于驅動輔助認證，
