f97cf1a168 Fix off-by-one error in HPA/AMA maximum reporting.
Before my refactoring the code reported value as maximum number of sectors,
adding one to the maximum sector number returned by respective command.
While this difference is somewhat confusing, restore previous behavior.

ca847845e3 Fix number of problems found while testing on SAT devices.
- Remove incomplete and dangerous ata_res decoding from ata_do_cmd().
Instead switch all functions that need the result to use get_ata_status(),
doing the same, but more careful, also reducing code duplication.
 - Made get_ata_status() to also decode fixed format sense.  In many cases
it is still not enough to make it useful, since it can only report results
of 28-bit command, but it is slightly better then nothing.
 - Organize error reporting in ata_do_cmd(), so that if caller specified
AP_FLAG_CHK_COND, it is responsible for command errors (non-ioctl ones).
 - Make HPA/AMA errors not fatal for `identify` subcommand.
 - Fix reprobe() not being called on HPA/AMA when in quiet mode.
 - Remove not very useful messages from `format` and `sanitize` commands
with -y flag.  Once they started, they often can't be stopped any way.

Error there mean that command was not even executed, and all information

16614d3518 Supply SAT layer with valid transfer sizes.
This is a rework of r344701, that noticed that number of bytes passes to
8 bit sector count field gets truncated.  First decision was to not pass
anything, since ATA specs define the field as N/A.  But it appeared to be a
problem for some SAT devices, that require information about data transfer
to operate properly.  Some additional investigation shown that it is quite
a common practice to set unused fields of ATA commands (fortunately ATA
specs formally allow it) to supply the information to SAT layer.  I have
found SAS-SATA interposer that does not allow pass-through without it.

As side effect, reduce code duplication by removing ata_do_28bit_cmd()
function, replacing it with more universal ata_do_cmd().

0912877616 Make camcontrol modepage support block descriptors.
It allows to read and write block descriptors alike to mode page parameters.
It allows to change block size or short-stroke HDDs or overprovision SSDs.
Depenting on -P parameter the change can be either persistent or till reset.
In case of block size change device may need reformat after the setting.
In case of SSD overprovisioning format or sanitize may be needed to really
free the flash.

During implementation appeared that csio_encode_visit() can not handle
integers of more then 4 bytes, that makes 8-byte LBA handling awkward.
I had to split it into two 4-byte halves now.

new ones may not be able to report all mode pages with 6 byte commands.

This patch makes camcontrol by default start with 10 byte commands and
fall back to 6 byte on ILLEGAL REQUEST error, or 6 byte can be forced.

237024606a Use a different approach to range check.
gcc hates dt < CC_DT_NONE since it can never be true when dt is an unsigned
type. Since that's a compiler choice and may be affected by weird stuff, instead
use (unsigned)dt > CC_DT_UNKNOWN to test for bounds error since that will work
regardless of the signedness of dt.

remain are for ancient parts that are no longer relevant. They are

and little to none of it would be relevant should someone need to
update to support raw nand. This code has been off by default for
years and has violated the vnode protocol leading to panics since it
was committed.

3ace9199b4 Make WD and WDC aliases for HGST.
HGST was bought by WDC. Over the years, it has sold different drives
branded as HGST, WD or WDC. All of them need the HGST workaround of
sending 4k-sized packets (or multiples of 4k). And the ones that don't
really need this aren't broken by this change. Submitter is the vendor
who has tested these changes on a number of drives. I've simplified it
slightly, since we don't need additional vendors for this at this
time.

b9dd559a32 Add -l to camcontrol readcap.
The -l flag sends only the READ CAPACITY (16) sevice action. Normally
we send the READ CAPACITY (10) command, and only send RC16 when the
capacity is larger than 2TB (since that's the max RC10 can
report). However, some badly programmed drives report different
numbers for RC10 and RC16. This can be hard to diagnose, but generally
there's a "Logical block address out of range" error when RC16 reports
a larger number than RC10 and the RC10 number is the correct one. By
comparing the output of readcap with and without the -l argmuent, one
can determine if there's a mismatch and if the DA_Q_NO_RC16 quirk is
needed.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

1e773aeb99 When editing a mode page on a tape drive, do not clear the device
specific parameter.

Tape drives include write protect (WP), Buffered Mode and Speed
settings in the device-specific parameter.  Clearing this
parameter on a mode select can have the effect of turning off
write protect or buffered mode, or changing the speed setting of
the tape drive.

Disks report DPO/FUA support via the device specific parameter
for MODE SENSE, but the bit is reserved for MODE SELECT.  So we
clear this for disks (and other non-tape devices) to avoid
potential errors from the target device.

	Clear the device-specific parameter in the mode page
	header if we're not operating on a tape drive.
