you would handle it in EvtIoInternalDeviceControl or EvtIoDefault. we do
not have SRB access directly, but you can easily get it by calling
WDF_REQUEST_PARAMETERS params;
WDF_REQUEST_PARAMETERS_INIT(¶ms);
SRB* srb = (SRB*) params.Parameters.Others.Arg1;
or
IoGetCurrentIrpStackLocation(WdfRequestWdmGetIrp(request))->Parameters.Scsi.Srb
if you want to dive into WDM

IRP_MJ_INTERNAL_DEVICE_CONTROL is aliased to IRP_MJ_SCSI. I think you
are
seeing SCSI SRBs. you can tell if the current irp stack
location->MinorFunction == IRP_MN_SCSI_CLASS (which is 0x1)

which ioctls 0x0 and 0x01 refer to? I'm seeing in my filter driver.
thanks

Doron
My driver is a lower filter driver for cdrom.sys and sits above
imapi.sys.
How do I handle IRP_MJ_SCSI in KMDF? Can I access Parameters.Scsi.Srb
directly or is there wdfxxxx function for it? Also, I do see various
MMC
commands such as ERASE in my filter when handling
IOCTL_SCSI_PASS_THROUGH_DIRECT
but I'm not seeing WRITE command. Any ideas?
Thanks! That helped.. Any ideas why I don't seeCDB:Write command? I
see all other commands
in either SCSI_PASS_THROUGH_DIRECT or in SRB.
I realized that you missed WdfRequestGetParameters. I didn't know
about casting
Arg1 to SRB....
