Hi Alex,

Yes this is a copy and paste error.  Dharani is correct... it should read pModeHeader10->BlockDescriptorLength;

Did you want to change this in your patch since it is directly related to Mode Select?

Thanks,
Ray

Good catch, Dharani.

Hi Ray,

Is this just a typo?

Thanks,
Alex

    Hi Alex,

In the file nvmeSnti.c and function SntiTranslateModeData()

/* Mode Select 10 */
        pModeHeader10 = (PMODE_PARAMETER_HEADER10)(GET_DATA_BUFFER(pSrb));

#pragma prefast(suppress:6011,"This pointer is not NULL")
        blockDescLength = pModeHeader6->BlockDescriptorLength;  // BUG -  pModeHeader6 is not initialized probably it should be pModeHeader10

thanks,
Dharani.

Hi all,

I am adding a patch to fix a bug related to Mode Select command when users enable/disable Volatile Write Cache. The changes I made are within SntiTranslateModeData routine of nvmeSnti.c to correctly locate the page code and program Dword 11 of NVMe submission entry before issuing Set Features command. The password is idt123. Please review it and provide feedbacks in next couple weeks.

Thanks,
Alex
