WHQL error. Log seen in wdflogdump [InputBufferLength length is zero]

AneeshSAneeshS Member Posts: 12

I am running WHQL on my KMDF driver. In particular the test DF - Fuzz zero length buffer IOCTL Test (Reliability) fails and I see the following text in the wdflogdump (!wdfkd.wdflogdump)

I am not sure (yet) whether the failure of the test is a symptom of the problem being indicated in the logs.

Here is the text in the log.

WDFREQUEST X InputBufferLength length is zero, 0xc0000023(STATUS_BUFFER_TOO_SMALL)

I realize the test is sending randomly generated IOCTLs with zero length input and output buffers.

Any ideas on what the above failure in the log might be saying about the driver?
