IoVolumeDeviceToDosName returns STATUS_INVALID_DEVICE_REQUEST

NTFSD
1

Hello,
I wrote a FileSystem Filter driver with two binaries…one for Win2K another
for Win2K3. Thanks for previously helping me figure out that I can’t build
a Win2K3 driver on a Win2K system.

I make the call in IRP_MJ_CREATE. In Win2K I call
RtlVolumeDeviceToDosName( ), and it works like a charm. I call the
IoVolumeDeviceToDosName( ) in the Win2K3 driver, and I get the error
‘STATUS_INVALID_DEVICE_REQUEST ((NTSTATUS)0xC0000010L)’
What am I missing?

Win2K works.
status = RtlVolumeDeviceToDosName( irpSp->DeviceObject, &DosName );

Win2K3 doesn’t work.
status = IoVolumeDeviceToDosName( irpSp->DeviceObject, &DosName );
Regards,
Here are snippets to show how the code works…

typedef
NTSTATUS
(*PSF_IO_VOLUME_DEVICE_TO_DOS_NAME) (
IN PVOID VolumeDeviceObject,
OUT PUNICODE_STRING DosName
);

typedef struct _SF_DYNAMIC_FUNCTION_POINTERS {
//
// The following routines should all be available on Windows XP (5.1)
and
// later.
//
PSF_REGISTER_FILE_SYSTEM_FILTER_CALLBACKS
RegisterFileSystemFilterCallbacks;
PSF_ATTACH_DEVICE_TO_DEVICE_STACK_SAFE AttachDeviceToDeviceStackSafe;
…
PSF_GET_VERSION GetVersion;
PSF_IO_VOLUME_DEVICE_TO_DOS_NAME IoVolumeDeviceToDosName;

} SF_DYNAMIC_FUNCTION_POINTERS, *PSF_DYNAMIC_FUNCTION_POINTERS;

SF_DYNAMIC_FUNCTION_POINTERS gSfDynamicFunctions = {0};
.
.
.
VOID
SfLoadDynamicFunctions ( )
{
…
RtlInitUnicodeString( &functionName, L"IoVolumeDeviceToDosName" );
gSfDynamicFunctions.IoVolumeDeviceToDosName =
MmGetSystemRoutineAddress( &functionName );
//This works, because I checked that
gSfDynamicFunctions.IoVolumeDeviceToDosName is not NULL.
}
.
.
.
NTSTATUS
SfCreate (
IN PDEVICE_OBJECT DeviceObject,
IN PIRP Irp )
{
…
PIO_STACK_LOCATION irpSp = IoGetCurrentIrpStackLocation( Irp );
…
status =
gSfDynamicFunctions.IoVolumeDeviceToDosName(irpSp->DeviceObject,
&DosName );

// This is where I get the error status = 'STATUS_INVALID_DEVICE_REQUEST
((NTSTATUS)0xC0000010L)
…
}

Thank you,

-SteveC

You are passing a wrong device object to the IoVolumeDeviceToDosName - this
function expects a device object from storage stack and not a device object
created by a file system filter. W2K should be failing it too to be
consistent.

Thanks for responding Alexei,
Where do I get a pointer to the storage stack device object? From the irp
sent to my SfCreate function?
Thanks again,
-Steven Cook.

There is no easy way to get it before IRP is completed by the underlying
file system.
You can retrieve it while processing mount request and store in your device
object extension.
