I suspect this error will be relatively common.
libata for example has
if (ata_id_has_wwn(args->id)) {
/* SAT defined lu world wide name */
/* piv=0, assoc=lu, code_set=binary, designator=NAA */
rbuf[num + 0] = 1;
rbuf[num + 1] = 3;
rbuf[num + 3] = ATA_ID_WWN_LEN;
num += 4;
ata_id_string(args->id, (unsigned char *) rbuf + num,
ATA_ID_WWN, ATA_ID_WWN_LEN);
num += ATA_ID_WWN_LEN;
}
rbuf[3] = num - 4; /* page len (assume less than 256 bytes) */
and most of the time IDE disks in a virtual machine are configured without
a WWN.
