Shadow slots are NULL before a command is submitted (thehost private area is zeroed at allocation) and are reset to NULL in_scsifront_put_rqid() once a request completes, so an in-range rqid thatdoes not correspond to an outstanding request makes the frontenddereference a NULL pointer.\nA malicious or buggy backend can thus crash the guest by returning aresponse whose rqid is in range but not in flight -- for example aspurious response before any command has been issued, or a duplicate ofone already completed.  The ring has only VSCSIIF_MAX_REQS (16) slots,so before the first command every in-range rqid selects a NULL slot.\nReject a response whose shadow slot is not
