Subject: [ntfsd] What IRQLs are ProtocolStatus() and
ProtocolStatusComplete() run on?
Hi all,
I need to get notice when the network linkup. Because there are no good way
to do it in user mode. so I developed a network protocol driver to this. I
create a event in user mode and let my driver reference it in kernel mode by
calling DeviceIoControl() in user mode and calling
ObReferenceObjectByHandle() in kernel mode dispatch routine.
But I don’t know how to triger this event when my ProtocolStatus be called
while a linkup event occures.
(1).I call KeSetEvent() in ProtocolStatus() but I got a bugchk A: touch
paged pool in a high IRQL level.
(2). I created a system thread when the driver recieved
ObReferenceObjectByHandle command from user mode. and tried to call
KeWaitForSingleObject() in it to wait another kernel event which I 'd like
the ProtocolStatus to triger. but also got a Bugchk A when call
KeWaitForSingleOBject() in my system thread.
What is your suggestion?
Thanks in advance for any help.
Lu
