Tracing the SRB status

NTDEV
1

Hi all,

I want to trace the SRB commands sent to the scsiport. This I want to do
from a filter driver installed as a DiskDrive/ScsiPort. The problem is I am not able confirm whether the command is SRB or not. Is there status flag or field which confirms this, like in the case of IOCTL call we can find out using
“currentIrpStack->Parameters.DeviceIoControl.IoControlCode”. Please let me know the similar thing is possible for srb status. Also comment whether I can trace all SRBs are not?

Thanks in advance

Ramesh

Create an INI file with this:

Localwpp.ini
DEFINE_CPLX_TYPE(SRB,WPP_LOGSRB, SCSI_REQUEST_BLOCK *,ItemSRB,“s”,
SRB, 0);
WPP_FLAGS(-DWPP_LOGSRB(x) WPP_LOGPAIR( sizeof(SCSI_REQUEST_BLOCK),
(x)));

To trace use something like this, assuming one of the Flags is
TRACELEVELONE:

SCSI_REQUEST_BLOCK Srb;

DoTraceMessage(TRACELEVELONE, “Hello, %!SRB!”,&Srb );

In your sources file need to add the INI file

RUN_WPP= $(SOURCES) -km -ini:localwpp.ini

There is updated documentation on WPP in the latest DDK, specially there
is a table with supported extended format strings. It also explains how
to define syntax of the complex type defined above.

“currentIrpStack->Parameters.DeviceIoControl.IoControlCode”.

Yes

IOCTL_SCSI_EXECUTE_IN
IOCTL_SCSI_EXECUTE_OUT
IOCTL_SCSI_EXECUTE_NONE

Thanks Maxim, for the reply.
I am interested in returning the various SRB status flags for test purpose and complete the IRP, as if returned from class port or miniport(the lower level).

So, in my filter driver, should I update the “Irp->UserBuffer” with SRB structure or “CurrentIrpStack->Parameters.Scsi.Srb” with the SRB structure. Or is there any other method.

I tried accessing the “CurrentIrpStack->Parameters.Scsi.Srb” variables, in the IRP_MJ_SCSI routine handler. But the system crashes if I access it’s values.

Best Regards
Ramesh

Hi Jose,

I am planning to set the CurrentIrpStack->Parameters.Scsi->Srb (“srb”) structure and complete the Irp in the IRP_MJ_SCSI routine handler to simulate the error conditions. The problem is, if I access the parameters of the Srb or try to copy the “srb” the system is crashing. I checked the address of the “srb” which is valid. My intension is generate different SRB status for testing purpose.

Thanks and Regards
Ramesh

You’re doing this only with requests that are IRP_MJ_SCSI (aka
IRP_MJ_INTERNAL_DEVICE_CONTROL) right?

Have you stepped through your code to see where you’re crashing when you
access the SRB? Presumably you have if you know that the srb address
you got is “valid”.

If all you want to do really is trace srbs sent to a scsiport driver you
might want to download scsiview from my website. It will trace srbs sent to
a scsiport driver. This might suffice.

Hi Peter,

I checked the address value and if it is valid then tried copying memory of
that
much (SRB) size. Even, I just tried to print the srb.Function or srb.Length.
But
system crashes after that. when I checked the input structure size it is 16
bytes. What could be the input structure here? Also please let me know how
to do the same for other IOCTLs.

Regards
Ramesh

Hi Mark,

I also need to return the SRB status as if it is returned from lower level.
This for testing purpose. I tried using your software. But with that also
the system crashes. Even in idle condition the system is crashing. I tested
this on Windows 2003 server.

Thanks and Regards
Ramesh
