本文要点：
介绍一种从显卡驱动入手的构造D3DHook的方法,DX9,DX9EX,DX10,DX11均试用,无需重启进程，注入即可使用。

以DX9为例。

前置知识：
1. API Hook的基础知识
2. DX绘图知识
3. 关于DX Hook 有很多种方法，传统的方法请自行查找资料。
4. Windows Display Driver 的基础知识

首先Vender驱动导出了一个叫做OpenAdapter的函数。
原型

1	typedef HRESULT APIENTRY _OpenAdapter(D3DDDIARG_OPENADAPTER

*pAdapterData);
通过观察这个函数的参数可以发现这两个结构体

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

typedef struct _D3DDDIARG_OPENADAPTER {      HANDLE                         hAdapter;           // in /out :  Runtime handle /out : Driver handle      UINT                           Interface;          // in :  Interface version      UINT                           Version;            // in :  Runtime version      CONST D3DDDI_ADAPTERCALLBACKS* pAdapterCallbacks;  // in :  Pointer to runtime callbacks      D3DDDI_ADAPTERFUNCS*           pAdapterFuncs;      // out: Driver function table      UINT                           DriverVersion;      // out: D3D UMD interface version the                                                         //      driver was compiled with. Use                                                         //      D3D_UMD_INTERFACE_VERSION. } D3DDDIARG_OPENADAPTER; typedef struct _D3DDDI_ADAPTERFUNCS {      PFND3DDDI_GETCAPS                       pfnGetCaps;      PFND3DDDI_CREATEDEVICE                  pfnCreateDevice;      PFND3DDDI_CLOSEADAPTER                  pfnCloseAdapter; } D3DDDI_ADAPTERFUNCS;

HookOpenAdapter代码

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

BOOL DetourOpenAdapter() { OpenAdapter = (_OpenAdapter *)GetProcAddress(GetModuleHandleA( "nvd3dum.dll" ), "OpenAdapter" ); if (OpenAdapter == NULL) { OpenAdapter = (_OpenAdapter *)GetProcAddress(GetModuleHandleA( "aticfx32.dll" ), "OpenAdapter" ); } if (OpenAdapter) { DetourRestoreAfterWith(); DetourTransactionBegin(); DetourUpdateThread(GetCurrentThread()); DetourAttach((void **)&OpenAdapter, WarpOpenAdapter); DetourTransactionCommit(); } return OpenAdapter != NULL; }

通过Hook OpenAdapter 可以得到pfnCreateDevice;
代码如下

1 2 3 4 5 6 7 8 9 10

HRESULT APIENTRY WarpOpenAdapter(D3DDDIARG_OPENADAPTER *pAdapterData) {      HRESULT ret = OpenAdapter(pAdapterData);      if (ret == S_OK && pAdapterData->pAdapterFuncs->pfnCreateDevice)      {          DdiCreateDevice = pAdapterData->pAdapterFuncs->pfnCreateDevice;          pAdapterData->pAdapterFuncs->pfnCreateDevice = WarpDdiCreateDevice;      }      return ret; }

pfnCreateDevice是Vender驱动上报给runtime的createDevice API.当APP调用CreateDevice最后会到厂商驱动的pfnCreateDevice; 替换厂商驱动上报给runtime的pfnCreateDevice函数指针,就可以实现Hook pfnCreateDevice。这样下次APP调用CreateDevice就会先进入我们的WarpDdiCreateDevice;
代码如下

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53

HRESULT APIENTRY WarpDdiCreateDevice(      HANDLE hAdapter,      D3DDDIARG_CREATEDEVICE *pDeviceData) {      // DdiCreateDevice must not be NULL if this path hit      HRESULT ret = DdiCreateDevice(hAdapter, pDeviceData);      if (pDeviceData->pDeviceFuncs->pfnPresent && gDetourFuncTable.DdiPresent.isAttatched == FALSE)      {          DdiPresent = pDeviceData->pDeviceFuncs->pfnPresent;          ULONG_PTR realTramponLine = DetourDDiPresent();          gDetourFuncTable.DdiPresent.isAttatched = TRUE;          gDetourFuncTable.DdiPresent.preFuncPtr = DdiPresent;          gDetourFuncTable.DdiPresent.TrampoLinePtr = (PFND3DDDI_PRESENT)realTramponLine;          gDetourFuncTable.DdiPresent.warpFuncPtr = WarpDdiPresent;      }      if (pDeviceData->pDeviceFuncs->pfnPresent1 && gDetourFuncTable.DdiPresent1.isAttatched == FALSE)      {          DdiPresent1 = pDeviceData->pDeviceFuncs->pfnPresent1;          ULONG_PTR realTramponLine = DetourDDiPresent1();          gDetourFuncTable.DdiPresent1.isAttatched = TRUE;          gDetourFuncTable.DdiPresent1.preFuncPtr = DdiPresent1;          gDetourFuncTable.DdiPresent1.TrampoLinePtr = (PFND3DDDI_PRESENT1)realTramponLine;          gDetourFuncTable.DdiPresent1.warpFuncPtr = WarpDdiPresent1;      }      DdiLock = pDeviceData->pDeviceFuncs->pfnLock;      DdiCreateResource = pDeviceData->pDeviceFuncs->pfnCreateResource;      DdiCreateResource2 = pDeviceData->pDeviceFuncs->pfnCreateResource2;      DdiUnlock = pDeviceData->pDeviceFuncs->pfnUnlock;      DdiBlt = pDeviceData->pDeviceFuncs->pfnBlt;      return ret; } typedef struct _D3DDDIARG_CREATEDEVICE {      HANDLE                          hDevice;                // in :  Runtime handle /out : Driver handle      UINT                            Interface;              // in :  Interface version      UINT                            Version;                // in :  Runtime Version      CONST D3DDDI_DEVICECALLBACKS*   pCallbacks;             // in :  Pointer to runtime callbacks      VOID*                           pCommandBuffer;         // in :  Pointer to the first command buffer to use.      UINT                            CommandBufferSize;      // in :  Size of the first command buffer to use.      D3DDDI_ALLOCATIONLIST*          pAllocationList;        // out: Pointer to the first allocation list to use.      UINT                            AllocationListSize;     // in :  Size of the allocation list that will be available                                                              //      when the first command buffer is submitted.      D3DDDI_PATCHLOCATIONLIST*       pPatchLocationList;     // out: Pointer to the first patch location list to use.      UINT                            PatchLocationListSize;  // in :  Size of the patch location list that will be available                                                              //      when the first command buffer is submitted.      D3DDDI_DEVICEFUNCS*             pDeviceFuncs;           // out: Driver function table      D3DDDI_CREATEDEVICEFLAGS        Flags;                  // in :  Flags #if (D3D_UMD_INTERFACE_VERSION >= D3D_UMD_INTERFACE_VERSION_WIN7)      D3DGPU_VIRTUAL_ADDRESS          CommandBuffer;          // out: GPU Virtual address to the command buffer to use. _ADVSCH_ #endif // D3D_UMD_INTERFACE_VERSION } D3DDDIARG_CREATEDEVICE;

观察参数D3DDDIARG_CREATEDEVICE *pDeviceData不难发现 pDeviceFuncs中有我们需要的一切绘图API,这里用到的函数如下:

1 2 3 4 5 6 7 8

PFND3DDDI_CREATEDEVICE DdiCreateDevice = NULL; PFND3DDDI_PRESENT DdiPresent = NULL; PFND3DDDI_PRESENT1 DdiPresent1= NULL; PFND3DDDI_LOCK DdiLock = NULL; PFND3DDDI_CREATERESOURCE DdiCreateResource = NULL; PFND3DDDI_CREATERESOURCE2 DdiCreateResource2 = NULL; PFND3DDDI_UNLOCK DdiUnlock = NULL; PFND3DDDI_BLT DdiBlt = NULL;

代码如下

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

HRESULT APIENTRY WarpDdiCreateDevice(      HANDLE hAdapter,      D3DDDIARG_CREATEDEVICE *pDeviceData) {      // DdiCreateDevice must not be NULL if this path hit      HRESULT ret = DdiCreateDevice(hAdapter, pDeviceData);      if (pDeviceData->pDeviceFuncs->pfnPresent && gDetourFuncTable.DdiPresent.isAttatched == FALSE)      {          DdiPresent = pDeviceData->pDeviceFuncs->pfnPresent;          ULONG_PTR realTramponLine = DetourDDiPresent();          gDetourFuncTable.DdiPresent.isAttatched = TRUE;          gDetourFuncTable.DdiPresent.preFuncPtr = DdiPresent;          gDetourFuncTable.DdiPresent.TrampoLinePtr = (PFND3DDDI_PRESENT)realTramponLine;          gDetourFuncTable.DdiPresent.warpFuncPtr = WarpDdiPresent;      }      if (pDeviceData->pDeviceFuncs->pfnPresent1 && gDetourFuncTable.DdiPresent1.isAttatched == FALSE)      {          DdiPresent1 = pDeviceData->pDeviceFuncs->pfnPresent1;          ULONG_PTR realTramponLine = DetourDDiPresent1();          gDetourFuncTable.DdiPresent1.isAttatched = TRUE;          gDetourFuncTable.DdiPresent1.preFuncPtr = DdiPresent1;          gDetourFuncTable.DdiPresent1.TrampoLinePtr = (PFND3DDDI_PRESENT1)realTramponLine;          gDetourFuncTable.DdiPresent1.warpFuncPtr = WarpDdiPresent1;      }      DdiLock = pDeviceData->pDeviceFuncs->pfnLock;      DdiCreateResource = pDeviceData->pDeviceFuncs->pfnCreateResource;      DdiCreateResource2 = pDeviceData->pDeviceFuncs->pfnCreateResource2;      DdiUnlock = pDeviceData->pDeviceFuncs->pfnUnlock;      DdiBlt = pDeviceData->pDeviceFuncs->pfnBlt;      return ret; }

到这里我们已经顺利拿到厂商的pfnPresent函数了,是不是有点兴奋呢？因为我们要做的任何绘图工作需要在pfnPresent之前完成。这样present才会把我们画的东西拷贝到屏幕上。
或许你会有一个疑问，APP已经在运行了，不会再调用CreateDevice了，这样我们的Hook不就无效了吗？
答案是这样的，既然APP调用CreateDevice,那我们就自己调用。我们来构造这样一个CreateDevice的条件，创建出来的d3dDevice还能在后面用来作为我们绘图的设备(OnRenderFrame).

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

BOOL TryInitD3D(HWND hWnd) {      D3DPRESENT_PARAMETERS d3dpp;      HRESULT hResult = D3DERR_INVALIDCALL;      ZeroMemory(&d3dpp, sizeof(d3dpp));      d3dpp.Windowed = TRUE;      d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;      d3dpp.BackBufferFormat = D3DFMT_UNKNOWN;      pd3dInternal = Direct3DCreate9(D3D_SDK_VERSION);      if (pd3dInternal != NULL)      {          hResult = pd3dInternal->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hWnd,              D3DCREATE_SOFTWARE_VERTEXPROCESSING,              &d3dpp, &pd3dDevInternal);      }      return hResult == S_OK && pd3dDevInternal != NULL && InitDx(); }

拿到pfnPresent之后做inlineHook

1 2 3 4 5 6 7 8 9 10 11 12 13 14

ULONG_PTR DetourDDiPresent1() {      ULONG_PTR realTrampoLine = NULL;      DetourRestoreAfterWith();      DetourTransactionBegin();      DetourUpdateThread(GetCurrentThread());      if (DdiPresent1)      {          DetourAttachEx((void **)&DdiPresent1, WarpDdiPresent1, (PDETOUR_TRAMPOLINE *)&realTrampoLine, NULL, NULL);      }      DetourTransactionCommit();      return realTrampoLine; }

然后在pfnPrsent的代理函数中做我们自己的绘图操作。里面涉及的函数下面会有解释
我实现了一个简单的pfnPresent1代理函数,在里面调用真正的pfnPresent1之前做我们的绘图（我是的WIN 8.1,WDDM1.3 所以就对pfnPresent1动手了）
代理函数如下

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47

HRESULT APIENTRY WarpDdiPresent1(      HANDLE hDevice,      CONST D3DDDIARG_PRESENT1 *pPresent1) {      static HANDLE wrapDevice = NULL;      static HANDLE hDestSurf = NULL;      static UINT cachedWidth = 0;      static UINT cachedHeight = 0;      RECT rc = { 0 };      RECT destRC = { 0 };      RECT srcRC = { 0 };      IDirect3DSurface9 * pSrcSurf = NULL;      HRESULT hRet = S_OK;          // 如果是运行中的app画图，就进入下面的流程进行我们的画图          // 反之是我们的画图操作，直接放过，避免重入      if (hDevice == wrapDevice || wrapDevice == NULL)      {          wrapDevice = hDevice;          if (S_OK == onRenderFrame(&pSrcSurf, &rc))          {              if (rc.right - rc.left != cachedWidth ||                  rc.bottom - rc. top != cachedHeight)              {                  cachedWidth = rc.right - rc.left;                  cachedHeight = rc.bottom - rc. top ;                  //TODO : destroy hDestSurf                  hDestSurf = CreateSurfaceforWDDM1_3(hDevice, cachedWidth, cachedHeight);              }              if (hDestSurf != NULL)              {                  destRC = srcRC = rc;                  hRet = SurfaceBltInternal(hDevice, hDestSurf, destRC, pSrcSurf, srcRC);              }              if (hRet == S_OK)              {                  BltToRTWDDM1_3(hDevice, hDestSurf, pPresent1,rc);              }          }      }      hRet = gDetourFuncTable.DdiPresent1.TrampoLinePtr(hDevice, pPresent1);      return hRet; }

HRESULT APIENTRY onRenderFrame(__out IDirect3DSurface9 ** pOutSurf, RECT * pOutRC)是我们的绘图函数，在这里实现我们要的东西，画到RenderTarget上，然后输出RenderTarget和它的大小。

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

HRESULT APIENTRY onRenderFrame(__out IDirect3DSurface9 ** pOutSurf, RECT * pOutRC) {      HRESULT hr;      RECT rc;      pd3dDev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_RGBA(0, 0, 0, 0), 1.0f, 0);      if (S_OK == pd3dDev->BeginScene())      {          hr = pd3dDev->SetRenderTarget(NULL, pRTSurf);          // 在这里画你需要的任何东西，没错 就是这么任性。          pd3dDev->EndScene();      }      if (hr == S_OK)      {          *pOutSurf = pRTSurf;          *pOutRC = rc;      }      else      {          *pOutSurf = NULL;          pOutRC-> top = 0;          pOutRC->left = 0;          pOutRC->bottom = 0;          pOutRC->right = 0;      }      return hr; }

当在WarpDdiPresent1得到我们的绘图结果（RenderTarget和大小）之后，我们就能把画好的结果拿出来，然后通过调用厂商提供的pfnBlt函数 贴到present的SrcSurf上。

//用上面拿到的pfnCreateResource2 创建一张surface 用来保存我们的绘图结果。

//调用厂商提供的pfnBLT把surafce上保存的图画 搬到 present的SrcSurf中，这样 present的时候 我们画的东西就展现出来了。
