Summary: kernel Object for drivers fail to be Deleted due to
unrealistic header PointerCount
Product: ReactOS
Version: TRUNK
Platform: Virtual PC
OS/Version: ReactOS
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: Kernel
AssignedTo: ros-bugs at reactos.org
ReportedBy: martinmnet at hotmail.com
QAContact: ros-bugs at reactos.org
The problem is in /ntoskrnl/io/iomgr/driver.c
The function IopCreateDriver
Status = ObInsertObject(DriverObject,
NULL,
FILE_READ_DATA,
OBJ_KERNEL_HANDLE,
NULL,
&hDriver);
This eventually ends up calling ObpCreateHandle
with OBJ_KERNEL_HANDLE value passed as the Additional References parameter.
And in ObpCreateHandle the PointerCount is incremented to this
OBJ_KERNEL_HANDLE value.
Debugging:
(ntoskrnl/ob/obref.c:308) ---> ObfDereferenceObject - Object: Driver, Address:
80e77048, PointerCount: 513
