Subject: Re: [nvmewin] FW: NVME fuzz test fixes<br>
<br>
Thanks for the great feedback. Fixed all and attached the new zip (same password). I also reran the tests, but for 3) the Microsoft fuzz test seems to have no coverage. It keeps asking for sense data with aloc length of 0 (like 100 times). I artificially tested
this by modifying the allocLength variable in kernel debugger.<br>
<br>

Iuliu,<br>
The changes look good.<br>
I have just a few comments.<br>
<br>
1. nvmeSnti.C/Line 1157 ? memset(pResponseBuffer, 0, allocLength); This was added to the comment, but it?s not clear why. I suspect it is an accidental addition. If so, this should be removed.<br>
<br>
2. nvmeSnti.c/Line 1519 ? Since the Lun value is actually written to the second byte of the entry, the comparison should be:<br>
<br>
if (lunIdDataOffset + SINGLE_LVL_LUN_OFFSET >= allocLength)<br>
<br>
<br>
<br>
As an example, test with a buffer size of 0x11. Without this change, the driver will actually write the byte after the allocated buffer.<br>
<br>
3. nvmeSnti.c/Line 2652 & 2669. Your change handles the case where there is no data buffer. But, it does not handle the case where the buffer is smaller than sizeof(DESCRIPTOR_FORMAT_SENSE_DATA). With a small buffer allocation, these writes would access
beyond the allocated buffer<br>
<br>
pSenseData->ErrorCode = FIXED_SENSE_DATA;<br>
<br>
pSenseData->SenseKey = SCSI_SENSE_NO_SENSE;<br>
<br>
pSenseData->AdditionalSenseLength = FIXED_SENSE_DATA_ADD_LENGTH;<br>
<br>
pSenseData->AdditionalSenseCode = SCSI_ADSENSE_NO_SENSE;<br>
<br>
pSenseData->AdditionalSenseCodeQualifier = 0;<br>

Hello,<br>
I have attached the fixes we (Google) did for the several crashes / corruptions exposed by the Windows HCK fuzztest.exe.<br>
We have tested this on qemu/ Server 2012 R2.<br>
The password on the zip is "nvme" :)<br>
