UWP无法访问KMDF驱动程序
本帖最后由 Segn 于 2022-5-24 15:58 编辑我正在学习KMDF驱动程序与UWP应用开发，尝试通过UWP应用与KMDF驱动程序通信，根据[面向应用开发人员的硬件支持应用 (HSA) 步骤 - Windows drivers | Microsoft Docs](https://docs.microsoft.com/zh-cn/windows-hardware/drivers/devapps/hardware-support-app--hsa--steps-for-app-developers)实现了，但是对驱动和UWP进行了一些更新后，UWP访问KMDF驱动会发生异常(拒绝访问。(Exception from HRESULT:0x80070005))
我不知道是否是在对UWP应用和驱动的更新过程中修改了什么发生了错误，因此我重新编写了一个驱动程序及其对应的UWP应用，同样发生了这个异常，下面是关于驱动程序和UWP应用的部分配置。
我想知道是什么导致了这个问题，如何解决这个问题？
驱动程序添加接口与自定义功能：
```cpp
WDFSTRING symbolicLinkString = NULL;
UNICODE_STRING symbolicLinkName = SymbolicName;//符号链接名称
DEVPROP_BOOLEAN isRestricted;
status = WdfDeviceCreateDeviceInterface(
Device,
(LPGUID)&GUID_DEVINTERFACE_HSADrvSample,//设备接口GUID
NULL); // Reference String
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\tWdfDeviceCreateDeviceInterface failed with errorcode:%x\n", status));
goto Error;
}
if (g_pIoSetDeviceInterfacePropertyData != NULL) {
status = WdfStringCreate(NULL,
WDF_NO_OBJECT_ATTRIBUTES,
&symbolicLinkString);
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\tWdfStringCreate failed with errorcode:%x\n", status));
goto Error;
}
status = WdfDeviceRetrieveDeviceInterfaceString(
Device,
(LPGUID)&GUID_DEVINTERFACE_HSADrvSample,
NULL,
symbolicLinkString);
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\tWdfDeviceRetrieveDeviceInterfaceString failed with errorcode:%x\n", status));
goto Error;
}
WdfStringGetUnicodeString(symbolicLinkString, &symbolicLinkName);
isRestricted = DEVPROP_TRUE;
status = g_pIoSetDeviceInterfacePropertyData(
&symbolicLinkName,
&DEVPKEY_DeviceInterface_Restricted,
0,
0,
DEVPROP_TYPE_BOOLEAN,
sizeof(isRestricted),
&isRestricted);
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\tIoSetDeviceInterfacePropertyData failed with errorcode:%x\n", status));
goto Error;
}
#if defined(NTDDI_WIN10_RS2) && (NTDDI_VERSION >= NTDDI_WIN10_RS2)
static const wchar_t customCapabilities[] = L"ColinTest.HSADrvSample_2022051717171\0";//自定义功能名称
status = g_pIoSetDeviceInterfacePropertyData(&symbolicLinkName,
&DEVPKEY_DeviceInterface_UnrestrictedAppCapabilities,
0,
0,
DEVPROP_TYPE_STRING_LIST,
sizeof(customCapabilities),
(PVOID)&customCapabilities);
if (!NT_SUCCESS(status)) {
KdPrint(("HSADrvSample:\tIoSetDeviceInterfacePropertyData failed with errorcode:%x\n", status));
goto Error;
}
#endif
WdfObjectDelete(symbolicLinkString);
}
Error:
if (symbolicLinkString != NULL) {
WdfObjectDelete(symbolicLinkString);
}
```
驱动程序INF文件

UWP包应用清单添加自定义功能：
```html
<Capabilities>
<Capability Name="internetClient" />
<uap4:CustomCapability Name="ColinTest.HSADrvSample_2022051717171"/>
</Capabilities>
```
UWP应用SCCD文件：
```html
<?xml version="1.0" encoding="utf-8"?>
<CustomCapabilityDescriptor xmlns="http://schemas.microsoft.com/appx/2018/sccd" xmlns:s="http://schemas.microsoft.com/appx/2018/sccd">
<CustomCapabilities>
<CustomCapability Name="ColinTest.HSADrvSample_2022051717171"></CustomCapability>
</CustomCapabilities>
<AuthorizedEntities AllowAny="true"/>
<Catalog>0000</Catalog>
</CustomCapabilityDescriptor>
```
UWP调用：
```C#
var selector = CustomDevice.GetDeviceSelector(DeviceInterfaceGuid);
Note.Text = "选择器：" + selector;
var enumDevice = DeviceInformation.FindAllAsync(selector).AsTask();
Task.WaitAll(enumDevice);
Note.Text = "找到了" + enumDevice.Result.Count + "个设备";
var DeviceID = enumDevice.Result.Id;
Note.Text = "设备ID：" + DeviceID;
try
{
var Device = CustomDevice.FromIdAsync(DeviceID, DeviceAccessMode.ReadWrite, DeviceSharingMode.Shared).AsTask();
Task.WaitAll(Device);
Note.Text = "设备打开成功";
}
catch (Exception ex)
{
Note.Text = ex.Message;
}
```
运行结果： 事实上，我犯了一个低级错误。
函数`g_pIoSetDeviceInterfacePropertyData`需要在`DriverEntry`中配置。
但是我没有，这导致了我设置的`CustomCapabilityName`没有生效。
```cpp
UNICODE_STRING funcName;
RtlInitUnicodeString(&funcName, L"IoSetDeviceInterfacePropertyData");
g_pIoSetDeviceInterfacePropertyData = (PFN_IO_SET_DEVICE_INTERFACE_PROPERTY_DATA)(ULONG_PTR)
MmGetSystemRoutineAddress(&funcName);
```
但是，为什么UWP应用在最开始能够访问我的驱动程序？
我想这仍是一个未解之谜......
大佬，我最近在学UMDF驱动，有些问题可以请教一下吗？

我也是新手，还没有接触UMDF驱动，不过你可以把你的问题说一下 Segn 发表于 2022-5-26 14:05

就是UMDF驱动安装后提示，此设备软件现已安装，但可能无法正确运行，然后设备那有一个感叹号 N0exp 发表于 2022-5-26 14:25

我并没有遇到过类似的错误，但我建议检查下驱动代码和INF文件
