[Bug 681196] New: ATA HDIO_GET_IDENTITY inqueries should not be send to SCSI devices (pass-through)
https://bugzilla.novell.com/show_bug.cgi?id=681196 https://bugzilla.novell.com/show_bug.cgi?id=681196#c0 Summary: ATA HDIO_GET_IDENTITY inqueries should not be send to SCSI devices (pass-through) Classification: openSUSE Product: openSUSE 11.4 Version: RC 2 Platform: All OS/Version: openSUSE 11.3 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: werner@novell.com QAContact: qa@suse.de CC: hare@novell.com, kasievers@novell.com, jbottomley@novell.com Depends on: 679277 Found By: Development Blocker: --- It is not a good idea to root the ATA HDIO_GET_IDENTITY to as SCSI 2 device, like CDROMs or CD-writes. Compare this with the rule at line 31ff in /lib/udev/rules.d/60-persistent-storage.rules For udev it is not possible to identify such devices with the vendor string as on both SCSI and ATAPI devices the reported vendor is not "ATA" but the real hardware/firmware vendor. The type of both SCSI and ATAPI devices is "5". IMHO the ata_id command should become a EPROTONOSUPPORT or EPFNOSUPPORT from the kernel. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

But the kernel knows that sending such commands to a SCSI-2 device will not work. Are you sure it should have any "faith" here?
It will if it's an ATA device behind a USB bridge. THat's the problem: there's no real way to filter out bogus stuff without breaking other stuff. The point is that the SG node is provided for the user to get around the restrictions we place on normal probing and commands ... the policy here is do whatever the user says. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
