- Make sure we don't release the READ CAPACITY CCB twice
- If we have a device that needs a 16 byte READ CAPACITY command, make
sure we call xpt_schedule() so we can get a CCB.
- Don't unlock the peripheral until we're fully probed.

when error == 0, and thus were not used uninitialized.
using 512 byte blocks).
cam_ccb.h: Bump up volume_size and cylinders in ccb_calc_geometry to
64 bits and 32 bits respectively, so we can hold larger
device sizes. cylinders would overflow at about 500GB.
Bump CAM_VERSION for this change. Note that this will
require a recompile of all applications that talk to the
pass(4) driver.
scsi_all.c: Add descriptions for READ/WRITE(16), update READ/WRITE(12)
descriptions, add descriptions for SERVICE ACTION IN/OUT.
Add a new function, scsi_read_capacity_16(), that issues
the read capacity service action. (Necessary for arrays
larger than 2^32 sectors.) Update scsi_read_write() to use
a 64 bit LBA and issue READ(16) or WRITE(16) if necessary.
NOTE the API change. This should be largely transparnet
to most userland applications at compile time, but will
break binary compatibility. The CAM_VERSION bump, above,
also serves the purpose of forcing a recompile for any
applications that talk to CAM.
scsi_all.h: Add 16 byte READ/WRITE structures, structures for 16 byte
READ CAPACITY/SERVICE ACTION IN. Add scsi_u64to8b() and
scsi_8btou64.
scsi_da.c: The da(4) driver probe now has two stages for devices
larger than 2TB. If a standard READ CAPACITY(10) returns
0xffffffff, we issue the 16 byte version of read capacity
to determine the true array capacity. We also do the same
thing in daopen() -- use the 16 byte read capacity if the
device is large enough.
The sysctl/loader code has also been updated to accept
16 bytes as a minimum command size.

someone adds another peripheral at the same unit number. (e.g. rescan da0,
it goes away, then rescan again and da0 comes back, but since we haven't
cleaned up the sysctl variables from the last da0 instance, we can't
register the variables for the new instance under the same name.)

Retire the "d_dump_t" and use the "dumper_t" type instead.
Dumper_t takes a void * as first arg which is more general than the
dev_t taken by d_dump_t. (Remember: we could have net-dumpers if
somebody wrote us one!)
Define the convention for GEOM controlled disk devices to be that the
first argument to the dumper function is the struct disk pointer.
Change device drivers accordingly.
Change the argument to disk_destroy() to be the same struct disk * as
disk_create() takes.
This enables drivers to ignore the (now) bogus dev_t which disk_create()
returns.
a number of related problems along the way.
- Automatically detect CDROM drives that can't handle 6 byte mode
sense and mode select, and adjust our command size accordingly.
We have to handle this in the cd(4) driver (where the buffers are
allocated), since the parameter list length is different for the
6 and 10 byte mode sense commands.
- Remove MODE_SENSE and MODE_SELECT translation removed in ATAPICAM
and in the umass(4) driver, since there's no way for that to work
properly.
- Add a quirk entry for CDROM drives that just hang when they get a 6
byte mode sense or mode select. The reason for the quirk must be
documented in a PR, and all quirks must be approved by
ken@FreeBSD.org. This is to make sure that we fully understand why
each quirk is needed. Once the CAM_NEW_TRAN_CODE is finished, we
should be able to remove any such quirks, since we'll know what
protocol the drive speaks (SCSI, ATAPI, etc.) and therefore whether
we should use 6 or 10 byte mode sense/select commands.
- Change the way the da(4) handles the no_6_byte sysctl. There is
now a per-drive sysctl to set the minimum command size for that
particular disk. (Since you could have multiple disks with
multiple requirements in one system.)
- Loader tunable support for all the sysctls in the da(4) and cd(4)
drivers.
- Add a CDIOCCLOSE ioctl for cd(4) (bde pointed this out a long
time ago).
- Add a media validation routine (cdcheckmedia()) to the cd(4)
driver, to fix some problems bde pointed out a long time ago. We
now allow open() to succeed no matter what, but if we don't detect
valid media, the user can only issue CDIOCCLOSE or CDIOCEJECT
ioctls.
- The media validation routine also reads the table of contents off
the drive. We use the table of contents to implement the
CDIOCPLAYTRACKS ioctl using the PLAY AUDIO MSF command. The
PLAY AUDIO TRACK INDEX command that we previously used was
deprecated after SCSI-2. It works in every SCSI CDROM I've tried,
but doesn't seem to work on ATAPI CDROM drives. We still use the
play audio track index command if we don't have a valid TOC, but
I suppose it'll fail anyway in that case.
- Add _len() versions of scsi_mode_sense() and scsi_mode_select() so
that we can specify the minimum command length.
- Fix a couple of formatting problems in the sense printing code.

Otherwise, the scsi devices that it is trying to issue commands to may
have gone away. This is what caused shutdown to hang on ia64 systems
with mpt scsi controllers. The bus system has torn down the device tree
and reset the mpt controller etc, and suddenly along comes dashutdown
and wants to issue a few more scsi commands.... <HANG!>
This shouldn't work on i386 either, but it seems to work solely due
to luck.
That reference is to be held only if daopen() has been successful
and until daclose() releases it. daclose() won't be called if
daopen() has failed, though.

and predictable way, and I apologize if I have gotten it wrong anywhere,
getting prior review on a patch like this is not feasible, considering
the number of people involved and hardware availability etc.)
If struct disklabel is the messenger: kill the messenger.
Inside struct disk we had a struct disklabel which disk drivers used to
communicate certain metrics to the disklayer above (GEOM or the disk
mini-layer). This commit changes this communication to use four
explicit fields instead.
Amongst the benefits is that the fields do not get overwritten by
wrong or bogus on-disk disklabels.
Once that is clear, <sys/disk.h> which is included in the drivers
no longer need to pull <sys/disklabel.h> and <sys/diskslice.h> in,
the few places that needs them, have gotten explicit #includes for
them.
The disklabel inside struct disk is now only for internal use in
the disk mini-layer, so instead of embedding it, we malloc it as
we need it.
This concludes (modulus any mistakes) the series of disklabel related
commits.
I belive it all amounts to a NOP for all the rest of you :-)

and upgrade to using 10 byte cdbs.
As far as I tested, this works efficiently for most of the
SBP-II/Firewire devices but most of the umass devices still need
ad-hoc work around because umass-sim doesn't return any SCSI errors.
A sysctl nob is also added for the last resort.
I hope we don't need DA_Q_NO_6_BYTE quirks anymore.
