Hi,
I wrote a simple driver to allocate memory and reclaim memory when I try to use stop service to stop the drivers it is saying “The requested control is not valid”. I am posting the source below.
NTSTATUS DriverEntry (PDRIVER_OBJECT DriverObject,PUNICODE_STRING RegistryPath)
{
DbgPrint(“Allocating Memory… \n”);
buffer = ExAllocatePoolWithTag(PagedPool,MAX_BUF,‘1GAT’);
if(!buffer)
{
DbgPrint(“ExAllocatePoolWithTag Failed \n”);
return STATUS_INSUFFICIENT_RESOURCES;
}
DbgPrint(“Allocated Memory. \n”);
DriverObject->DriverUnload = DriverUnload;
return STATUS_SUCCESS;
}
void DriverUnload(PDRIVER_OBJECT pDriverObject)
{
DbgPrint(“Freeing Memory… \n”);
ExFreePoolWithTag(buffer,‘1GAT’);
DbgPrint(“Freed Memory… \n”);
DbgPrint(“Driver unloading\n”);
}
