[nvmewin] Potential bug in OFA driver 1.3

[Alex Chang]

Hi Parag,

When we added supporting SRB Extension for Windows 8 and up, there is no plan that supports Windows 8 + SCSI_REQUEST_BLOCK. To be more specific, we need to indicate that via SrbTypeFlags of HW_INITIALIZATION_DATA. However, Windows 8 always sends down STORAGE_REQUEST_BLOCK when SrbTypeFlags is set to zero. Is that what you’re seeing on your testing?

Thanks,
Alex

Hi All,

With the latest 1.3 driver, STORAGE_REQUEST_BLOCK support has been added for windows 8 and up. Is this the only configuration allowed with Windows 8 or SCSI_REQUEST_BLOCK + windows 8 combination is allowed as well? If allowed, than there are couple of bugs in the way srbhelper (from wdk) is being used. Specifically SrbSetScsiData() and SrbGetScsiData() from srbhelper do not handle SCSI_REQUEST_BLOCK properly and will cause command failure.

Thanks
