Perhaps the "best" fix here is to simply make scsi_scan.c only send 36 byte
inquiry requests if the bus is 'emulated'. That would solve a world of
problems....
When scsi_scan.c does it's own scanning for SCSI Core, maybe it's best to
ignore 36 < INQUIRY_DATA_LEN < 57, since this is just vendor specific
data and SCSI Core is not interested in it.
In descriptive-C this looks like this:
</issue a 36 byte buffer INQUIRY/>
</now dissect:/>
int bytes_got = max(bytes_requested - cmd->resid, 0);
if (31 < buffer[4] && buffer[4] < 52) {
/* we don't care, do not issue another INQUIRY */
else if (buffer[4] >= 52) {
bytes_requested = 5+buffer[4];
/* issue another INQUIRY to get the additional flags, */
/* plus any version descriptors if available */
</insert code here/>
bytes_got = max(bytes_requested - cmd->resid, 0);
}
if (bytes_got != buffer[4]+5) {
/* let's rely on the transport to have correctly set */
/* cmd->resid and report a broken device server */
</insert code here/>
}
/* Now we rely on bytes_got */
</rest of scanning code/>
