RE: Security Attributes on a Notification Event created at Kernel level

This is what I had to do also, creating the event in user space and pass the
handle to the driver. I remember some MSJ article describing this as the
suggested approach. Creating the event as a driver only seems to work if
you are a service, or have administrator rights.

On simpler solution would be to create an named event in your app and open
the same event in the kernel. In this case you can do any thing with it in
kernel and user mode

Subject: [ntdev] Security Attributes on a Notification Event created at
Kernel level

Abstract:
Does someone know if it is possible to have full access on a Notification
Event created in a Kernel driver?

Summary:

  • In a driver, I created a named event with IoCreateNotificationEvent
    function.
  • In an Application, I openned this event with OpenEvent function
  • I can only open the event with OpenEvent(SYNCHRONIZE, FALSE,
    szEventName), which give me access to test and wait the event. If I try
    OpenEvent(EVENT_ALL_ACCESS, FALSE, szEventName), I get an access denied on
    the open function.

Questions:
Is there some calls I could do at kernel level that will enable my
application to have SetEvent, ResetEvent permissions on the event? Are
there security attributes on the event?
