Hi Zoltan,
I saw your CoolStorage code. I want to do some similar, to create a
virtual disk from a file. And the user can mount files as drives.
Why write the same code? If you want to use KoolStorage for non-commercial
use it’s free for it. If not we can license you either binaries or full
source code.
And in a week or so there will be full SCSI port driver in addition to SCSI
miniport.
I have 2 drivers SCSI miniport and simple driver to provide data for
miniport and for user action.
I ran into the following problem:
I want to send a request from my SCSI miniport driver to another >driver
to get some data.
If the inputBuffer and outputBuffer is NULL it’s working fine, but if >the
outputBuffer is not NULL (I expect some return data) I got a crash.
The strange thing the ZwDeviceIoControlFile returned with SUCCESS, but
nothing came back in the outputBuffer.
The stack is:
ntoskrnl!KiDeliverApc + 0084
hal!HalClearSoftwareInterrupt + 0320
So I thought I need a completion function fro the >ZwDeviceIoControlFile,
but it’s never been called 
Any thoughts?
From where do you call ZwDeviceIoControlFile()? IRQL & thread context?
IRQL must be PASSIVE_LEVEL and thread context must be system thread
context. Queue a work item and call any file I/O from it. Use timer
callback as there is no other way to complete requests from SCSIPORT
context in miniport driver.
Regards,
Anton
