Description
The SMB2 server should fail with STATUS_INVALID_PARAMETER if the size of a MxAc create context is not large enough to hold the optional timestamp value. This is something the WPTS checks for by issuing a bogus CREATE request with a MxAc create context with a size of 4 bytes (the spec says it MUST be either 0 or 8 bytes long):
"The Data in the Buffer field of the SMB2_CREATE_CONTEXT MUST either contain the following structure or be empty (0 bytes in length)."
