Hi there people,

I have problem running the following driver code. It worked for sometime
but without no obvious reason whenever I try to stop the driver service
a BSOD appears with the PAGE_FAULT_IN_NON_PAGED_AREA error.
I found out that when I remove the set DriverName code the problem disappears
but the question is why.

I'm desperate I cant find a way to fix this thing. I load the driver
with the instdrv.In the Debug Viewer only the HI message apperars Any ideas?

Here is the code

VOID UnLoadMe(IN PDRIVER_OBJECT obj);
UNICODE_STRING us;

NTSTATUS DriverEntry ( IN PDRIVER_OBJECT theDriverObject, IN PUNICODE_STRING
theRegistryPath )
{

DbgPrint("HELLO");
RtlInitUnicodeString( &us, L"TEST\0" );
theDriverObject->DriverName=us;
theDriverObject->DriverUnload=UnLoadMe;
return STATUS_SUCCESS;
}


VOID UnLoadMe(IN PDRIVER_OBJECT obj)
{
DbgPrint("BYE");
}

You CAN'T do that... Why do you think you can?

alexander is correct, you cannot reassign this value. this field is owned
by the io manager. since the io manager owns it, it thinks it can free it,
which it does on unload. since the buffer points to a constant in your
driver's image and not from pool, it blows up.

Thanks for the info, but how can I set my drivers name?

I thought I can do that because in driver tree I 've seen the driver listed
with the name set.

You can try setting a new driver name in the INF file.

If you still want to change in the code you can directly change the
theDriverObject->DriverName
by either Initializing that string or by RtlCopyUnicodeString. The latter
would be better.
