STATUS_INSUFFICIENT_RESOURCES being returned from WdfRequestRetrieveInputBuffer...

NTDEV
1

I am porting a WDM virtual CD driver to WDF and in my handling code for
IOCTL_CDROM_GET_DRIVE_GEOMETRY WdfRequestRetrieveInputBuffer is
returning STATUS_INSUFFICIENT_RESOURCES, even though I have plenty of
memory available. Any ideas what would cause this?

Thanks,
–Jeremy

Did you give a minimum size for the input buffer on this call? If so,
was it bigger than the buffer you actually received?

Actually, that can’t be it. My apologies for missing that (it’d be
“buffer too small”).

I’m passing 0 as the minimum size (but like you said in your next post,
if that were the problem the error would be BUFFER_TOO_SMALL).

What size are you specifying for the required buffer length?

Odd- you ought to get that return, anyway, because this IOCTL has no
input buffer, per the WDK docs (but the sender may not have followed the
rules). Which makes me wonder why you want it?

Be that as it may, turning on the Wdf verifier and using traceview or
!wdflogdump (which will need symbols) to look at the trace info should
say why this was getting bounced that way.

Sorry for the imprecise pronouns. By the first paragraph, I meant
STATUS_BUFFER_TOO_SMALL is what you should have seen, anyway [unless the
caller specified an input buffer even though the IOCTL doesn’t require
one].

It would be good to see a trace.

My bad… some of my code was adapted from the nonpnp wdf sample which
converts all errors from WdfRequestRetrieveInputBuffer into
STATUS_INSUFFICIENT_RESOURCES, so that is what I saw in my logs. The
actual error code I’m getting is STATUS_BUFFER_TOO_SMALL.

What are you looking at in the WDK docs that indicates that the IOCTL
doesn’t have an input buffer? Is it because the purpose of the control
code is to get data rather than set data, or is there something more
specific that you are looking at?

Thanks,

The docs don’t specifically say “there is no input buffer”, but the fact
that the only documented “input” is the length of the output buffer
seems to make a pretty strong case.

Yes. If there is an input buffer, then the input section would tell you
its address and size. So not being there means there is none.

This does assume you can trust the documentation;>.
