Bug in Win 2k3 SP2 StorPort.sys

NTDEV
1

I believe there is a bug in Windows 2003 SP2 StorPort.sys. It appears
that it is failing the IOCTL_SCSI_GET_INQUIRY_DATA call if the number of
busses is >= 8. I believe that the test should be > 8.

Or … was there some reason this restriction was added?

Hopefully someone from Microsoft could address this.

Thanks,

Jerry.

have you debugged storport.sys to find out that it really fails for >= 8 ??
it seems, it doesnt check number of buses - only size of input data buffer; what error code DeviceIoControl returned?

It returns 0xC0000010, STATUS_INVALID_DEVICE_REQUEST.

Yes we have debugged StorPort.sys. Here’s the sequence.

storport!RaidAdapterScsiGetInquiryDataIoctl+0x36:
f727e888 0fb68f00010000 movzx ecx,byte ptr [edi+100h]
f727e88f 83f908 cmp ecx,8
f727e892 8b474c mov eax,dword ptr [edi+4Ch]
f727e895 894df8 mov dword ptr [ebp-8],ecx
f727e898 7210 jb
storport!RaidAdapterScsiGetInquiryDataIoctl+0x58 (f727e8aa)
f727e89a 8d4de0 lea ecx,[ebp-20h]
f727e89d ff1548b028f7 call dword ptr
[storport!_imp_KeReleaseInStackQueuedSpinLock (f728b048)]
f727e8a3 68100000c0 push 0C0000010h
f727e8a8 eb29 jmp
storport!RaidAdapterScsiGetInquiryDataIoctl+0x81 (f727e8d3)

When we change the driver to set ConfigInfo->NumberOfBuses to less than 8,
things work fine - the jb takes and the call succeeds.
