How to get the driver name from PDRIVER_OBJECT

NTDEV

Hello,

I’ve run the code analysis on the usbip-win project.
I get the following warning:

driver\stub\stub_dev.c(130): warning C28175: The 'DriverName' member of _DRIVER_OBJECT should not be accessed by a driver:  Access to this member may be permitted for certain classes of drivers. See the documentation for this warning for more information.

The source code follows as below:

static BOOLEAN
is_usbip_stub_attached(PDEVICE_OBJECT pdo)
{
	DEVICE_OBJECT	*attached;

	attached = pdo->AttachedDevice;
	while (attached) {
		PDRIVER_OBJECT	drvobj = attached->DriverObject;

		if (drvobj != NULL) {
			UNICODE_STRING	name_uni;
			RtlInitUnicodeString(&name_uni, L"\\driver\\usbip_stub");
			if (RtlEqualUnicodeString(&drvobj->DriverName, &name_uni, TRUE))
				return TRUE;
		}
		attached = attached->AttachedDevice;
	}
	return FALSE;
}

I’ve found that I can get the ‘DriverName’ member of _DRIVER_OBJECT using ObQueryNameString() API via the following discussion:
Getting driver name from PDRIVER_OBJECT
I have checked the usage of the ObQueryNameString() API, but I couldn’t find the relevant example code.

I hope someone to let me know how to get the driver name of PDRIVER_OBJECT using ObQueryNameString() API.
If there is another method to get the driver name, please let me know.

Thanks,
Andrey
