way st(4) does. Have both decline to open read-only devices for
anything but read-only access.
Suggestion to fail opens rather than individual i/o's from deraadt@.

to 18 bytes by removing the extra_bytes field. sbic.c was the only
consumer, and that was in a DEBUG message.
18 bytes is the minimum length mandated by the SCSI spec. Anything
more is vendor/device specific information.
This fixes a usb key that yuo@ had, and probably others.
Any device that decides to pay attention to extra sense data must
allocate its own space.

SCSI when you're talking to a scsi to ata translation layer (satl). this
implements the ata command ioctl handler in scsi_ioctl.c that wraps the
ata command requests up in these scsi commands and then issues them against
the hardware. this cuts atascsi over to interpreting these scsi commands
rather than the ioctls directly.
this should allow mpi users (with a relatively recent firmware) to use
atactl against their SATA disks. i cant test cos my mpi(4) parts are too
old to either support these scsi commands or too old to take recent
firmwares.

asc/ascq handling to deal with the pair together rather than seperately, since
modern scsi has long since polluted the "categories" of asc enough that you
pretty much need to always look as ascq.

obtained probe the LUNs given without checking for duplicate INQUIRY
data.
For non-USB, non-ATAPI, devices claiming to be SCSI-3 compliant. And
the target must have something attached at LUN 0.
If REPORT LUNS can't be used or isn't supported, the old scan process
is used.
Fixes Fibre Channel and SCSI enclosure devices that provide identical
INQUIRY data for all LUNs and were thus being misprobed as having
only LUN 0.

so eliminate code dealing with 16 byte block descriptors. No one else
seems to use them anyway. Add define for appropriate permission bit in
case we ever need it.
Simplify and clean up scsi_do_mode_sense() code as a result.
Strengthen check to ensure block descriptor data is a valid by
checking if it is a multiple of 8 bytes rather than just > 8 bytes.
Moves code to closer to what it was before scsi_do_mode_sense().
|
|
Add 'big' parameter to report which mode sense header type is being
returned. Eliminate icky pointer arithmetic, since it won't work if
only block descriptors are returned by the device.
No functional change.

both 10 byte and 6 byte MODE SENSE commands and just return error
checked values.
Convert sd_scsi.c to use new mechanism for non-optical drives. USB
umass devices will now display actual mode sense info if it is
available via a 10 byte MODE SENSE. Which may mean 0 heads, etc. is
shown until cosmetics are finalized.

in the tree is #ifdef'd out and is fundamentally wrong anyway - it
tries to force *all* devices to SCSI-2. Also recent SCSI specs seem to
have marked the command as obsolete. Bonus - eliminates another
undocumented option (SCSI_2_DEF).

1) Correctly define MODE_SENSE_BIG as 0x5a, not 0x54.
2) Delete duplicate #define's of some opcodes in scsi_disk.h.
3) Delete multiple #define's for same opcode in scsi_disk.h.
4) Replace uses of deleted opcodes in umass.c with remaining ones.

scsi_inquiry_data structure.
The last commit made the structure 57 bytes long, an odd number. This
caused problems with at least two drivers, which were not prepared to
handle the IGNORE WIDE RESIDUE message during probing. This message
apparently being generated during probes of non-existant LUNs.
Problem found on siop by Rev. Chris Cappuccio and on iha by Andreas
Gunnarsson <andreas@zzlevo.net>.

bringing it in line with the spc-2 definition of standard
inquiry data.
scsi_inquiry_data grows from 50 to 57 bytes in size.
The new 'flags2' field gives access to PPR related
information, the IUS, QAS and DT bits, used
in negotiating Ultra3 transfers.
Also add PPR related extended message defines.
