40152db5d3 Use the more proper term of SATL instead of ATA_BEHIND_SCSI.
Most people know SAS attached SATA devices by the name SAT or SATL
(with the latter being a little more common). Change the device type
ATA_BEHIND_SCSI to SATL since it's more specific and meaningful.

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.

492a2ef556 Add task attribute support to camcontrol(8).
Users can use the new generic argument, -Q task_attr, to specify a task
attribute (simple, ordered, head of queue, aca) for the commands issued.
The the default is simple, which works with all SCSI devices that support
tagged queueing.

This will mostly be useful for debugging target behavior in certain
situations.

You can try it out by compiling CTL with CTL_IO_DELAY turned on (in
sys/cam/ctl/ctl_io.h) and then do something like this with one of the CTL
LUNs:

ctladm delay 0:0 -l done -t 10
camcontrol tur da34 -v

And at then before the 10 second timer is up, in another terminal:

camcontrol inquiry da34 -Q ordered -v

The Inquiry should complete just after the TUR completes.  Ordinarily
it would complete first because of the delay injection, but because the
task attribute is set to ordered in this case, CTL holds it up until the
previous command has completed.

sbin/camcontrol/camcontrol.c:
	Add the new generic argument, -Q, which allows the user to specify
	a SCSI task attribute.  The user can specify task attributes by
	name or numerically.

	Add a new task_attr arguments to SCSI sub-functions.

sbin/camcontrol/attrib.c,
sbin/camcontrol/camcontrol.h,
sbin/camcontrol/fwdownload.c,
sbin/camcontrol/modeedit.c,
sbin/camcontrol/persist.c,
sbin/camcontrol/timestamp.c,
sbin/camcontrol/zone.c:
	Add the new task_attr argument to SCSI sub-functions.

sbin/camcontrol/camcontrol.8:
	Document the new -Q option, and add an example.

28db0a5e74 Add SCSI REPORT TIMESTAMP and SET TIMESTAMP support.
This adds support to camcontrol(8) and libcam(3) for getting and setting
the time on SCSI protocol drives.  This is more commonly found on tape
drives, but is a SPC (SCSI Primary Commands) command, and may be found
on any device that speaks SCSI.

The new camcontrol timestamp subcommand allows getting the current device
time or setting the time to the current system time or any arbitrary time.

sbin/camcontrol/Makefile:
	Add timestamp.c.

sbin/camcontrol/camcontrol.8:
	Document the new timestamp subcommand.

sbin/camcontrol/camcontrol.c:
	Add the timestamp subcommand to camcontrol.

sbin/camcontrol/camcontrol.h:
	Add the timestamp() function prototype.

sbin/camcontrol/timestamp.c:
	Timestamp setting and reporting functionality.

sys/cam/scsi/scsi_all.c:
	Add two new CCB building functions, scsi_set_timestamp() and
	scsi_report_timestamp().  Also, add a new helper function,
	scsi_create_timestamp().

sys/cam/scsi/scsi_all.h:
	Add CDB and parameter data for the the set and report timestamp
	commands.

	Add function declarations for the new CCB building and helper
	functions.

9a6844d55f Add support for managing Shingled Magnetic Recording (SMR) drives.
This change includes support for SCSI SMR drives (which conform to the
Zoned Block Commands or ZBC spec) and ATA SMR drives (which conform to
the Zoned ATA Command Set or ZAC spec) behind SAS expanders.

This includes full management support through the GEOM BIO interface, and
through a new userland utility, zonectl(8), and through camcontrol(8).

This is now ready for filesystems to use to detect and manage zoned drives.
(There is no work in progress that I know of to use this for ZFS or UFS, if
anyone is interested, let me know and I may have some suggestions.)

Also, improve ATA command passthrough and dispatch support, both via ATA
and ATA passthrough over SCSI.

Also, add support to camcontrol(8) for the ATA Extended Power Conditions
feature set.  You can now manage ATA device power states, and set various
idle time thresholds for a drive to enter lower power states.

Note that this change cannot be MFCed in full, because it depends on
changes to the struct bio API that break compatilibity.  In order to
avoid breaking the stable API, only changes that don't touch or depend on
the struct bio changes can be merged.  For example, the camcontrol(8)
changes don't depend on the new bio API, but zonectl(8) and the probe
changes to the da(4) and ada(4) drivers do depend on it.

Also note that the SMR changes have not yet been tested with an actual
SCSI ZBC device, or a SCSI to ATA translation layer (SAT) that supports
ZBC to ZAC translation.  I have not yet gotten a suitable drive or SAT
layer, so any testing help would be appreciated.  These changes have been
tested with Seagate Host Aware SATA drives attached to both SAS and SATA
controllers.  Also, I do not have any SATA Host Managed devices, and I
suspect that it may take additional (hopefully minor) changes to support
them.

Thanks to Seagate for supplying the test hardware and answering questions.

sbin/camcontrol/Makefile:
	Add epc.c and zone.c.

sbin/camcontrol/camcontrol.8:
	Document the zone and epc subcommands.

sbin/camcontrol/camcontrol.c:
	Add the zone and epc subcommands.

	Add auxiliary register support to build_ata_cmd().  Make sure to
	set the CAM_ATAIO_NEEDRESULT, CAM_ATAIO_DMA, and CAM_ATAIO_FPDMA
	flags as appropriate for ATA commands.

	Add a new get_ata_status() function to parse ATA result from SCSI
	sense descriptors (for ATA passthrough over SCSI) and ATA I/O
	requests.

sbin/camcontrol/camcontrol.h:
	Update the build_ata_cmd() prototype

	Add get_ata_status(), zone(), and epc().

sbin/camcontrol/epc.c:
	Support for ATA Extended Power Conditions features.  This includes
	support for all features documented in the ACS-4 Revision 12
	specification from t13.org (dated February 18, 2016).

	The EPC feature set allows putting a drive into a power power mode
	immediately, or setting timeouts so that the drive will
	automatically enter progressively lower power states after various
	idle times.

sbin/camcontrol/fwdownload.c:
	Update the firmware download code for the new build_ata_cmd()
	arguments.

sbin/camcontrol/zone.c:
	Implement support for Shingled Magnetic Recording (SMR) drives
	via SCSI Zoned Block Commands (ZBC) and ATA Zoned Device ATA
	Command Set (ZAC).

	These specs were developed in concert, and are functionally
	identical.  The primary differences are due to SCSI and ATA
	differences.  (SCSI is big endian, ATA is little endian, for
	example.)

	This includes support for all commands defined in the ZBC and
	ZAC specs.

sys/cam/ata/ata_all.c:
	Decode a number of additional ATA command names in ata_op_string().

	Add a new CCB building function, ata_read_log().

	Add ata_zac_mgmt_in() and ata_zac_mgmt_out() CCB building
	functions.  These support both DMA and NCQ encapsulation.

sys/cam/ata/ata_all.h:
	Add prototypes for ata_read_log(), ata_zac_mgmt_out(), and
	ata_zac_mgmt_in().

sys/cam/ata/ata_da.c:
	Revamp the ada(4) driver to support zoned devices.

	Add four new probe states to gather information needed for zone
	support.

	Add a new adasetflags() function to avoid duplication of large
	blocks of flag setting between the async handler and register
	functions.

	Add new sysctl variables that describe zone support and paramters.

	Add support for the new BIO_ZONE bio, and all of its subcommands:
	DISK_ZONE_OPEN, DISK_ZONE_CLOSE, DISK_ZONE_FINISH, DISK_ZONE_RWP,
	DISK_ZONE_REPORT_ZONES, and DISK_ZONE_GET_PARAMS.

sys/cam/scsi/scsi_all.c:
	Add command descriptions for the ZBC IN/OUT commands.

	Add descriptions for ZBC Host Managed devices.

	Add a new function, scsi_ata_pass() to do ATA passthrough over
	SCSI.  This will eventually replace scsi_ata_pass_16() -- it
	can create the 12, 16, and 32-byte variants of the ATA
	PASS-THROUGH command, and supports setting all of the
	registers defined as of SAT-4, Revision 5 (March 11, 2016).

	Change scsi_ata_identify() to use scsi_ata_pass() instead of
	scsi_ata_pass_16().

	Add a new scsi_ata_read_log() function to facilitate reading
	ATA logs via SCSI.

sys/cam/scsi/scsi_all.h:
	Add the new ATA PASS-THROUGH(32) command CDB.  Add extended and
	variable CDB opcodes.

	Add Zoned Block Device Characteristics VPD page.

	Add ATA Return SCSI sense descriptor.

	Add prototypes for scsi_ata_read_log() and scsi_ata_pass().

sys/cam/scsi/scsi_da.c:
	Revamp the da(4) driver to support zoned devices.

	Add five new probe states, four of which are needed for ATA
	devices.

	Add five new sysctl variables that describe zone support and
	parameters.

	The da(4) driver supports SCSI ZBC devices, as well as ATA ZAC
	devices when they are attached via a SCSI to ATA Translation (SAT)
	layer.  Since ZBC -> ZAC translation is a new feature in the T10
	SAT-4 spec, most SATA drives will be supported via ATA commands
	sent via the SCSI ATA PASS-THROUGH command.  The da(4) driver will
	prefer the ZBC interface, if it is available, for performance
	reasons, but will use the ATA PASS-THROUGH interface to the ZAC
	command set if the SAT layer doesn't support translation yet.
	As I mentioned above, ZBC command support is untested.

	Add support for the new BIO_ZONE bio, and all of its subcommands:
	DISK_ZONE_OPEN, DISK_ZONE_CLOSE, DISK_ZONE_FINISH, DISK_ZONE_RWP,
	DISK_ZONE_REPORT_ZONES, and DISK_ZONE_GET_PARAMS.

	Add scsi_zbc_in() and scsi_zbc_out() CCB building functions.

	Add scsi_ata_zac_mgmt_out() and scsi_ata_zac_mgmt_in() CCB/CDB
	building functions.  Note that these have return values, unlike
	almost all other CCB building functions in CAM.  The reason is
	that they can fail, depending upon the particular combination
	of input parameters.  The primary failure case is if the user
	wants NCQ, but fails to specify additional CDB storage.  NCQ
	requires using the 32-byte version of the SCSI ATA PASS-THROUGH
	command, and the current CAM CDB size is 16 bytes.

sys/cam/scsi/scsi_da.h:
	Add ZBC IN and ZBC OUT CDBs and opcodes.

	Add SCSI Report Zones data structures.

	Add scsi_zbc_in(), scsi_zbc_out(), scsi_ata_zac_mgmt_out(), and
	scsi_ata_zac_mgmt_in() prototypes.

sys/dev/ahci/ahci.c:
	Fix SEND / RECEIVE FPDMA QUEUED in the ahci(4) driver.

	ahci_setup_fis() previously set the top bits of the sector count
	register in the FIS to 0 for FPDMA commands.  This is okay for
	read and write, because the PRIO field is in the only thing in
	those bits, and we don't implement that further up the stack.

	But, for SEND and RECEIVE FPDMA QUEUED, the subcommand is in that
	byte, so it needs to be transmitted to the drive.

	In ahci_setup_fis(), always set the the top 8 bits of the
	sector count register.  We need it in both the standard
	and NCQ / FPDMA cases.

sys/geom/eli/g_eli.c:
	Pass BIO_ZONE commands through the GELI class.

sys/geom/geom.h:
	Add g_io_zonecmd() prototype.

sys/geom/geom_dev.c:
	Add new DIOCZONECMD ioctl, which allows sending zone commands to
	disks.

sys/geom/geom_disk.c:
	Add support for BIO_ZONE commands.

sys/geom/geom_disk.h:
	Add a new flag, DISKFLAG_CANZONE, that indicates that a given
	GEOM disk client can handle BIO_ZONE commands.

sys/geom/geom_io.c:
	Add a new function, g_io_zonecmd(), that handles execution of
	BIO_ZONE commands.

	Add permissions check for BIO_ZONE commands.

	Add command decoding for BIO_ZONE commands.

sys/geom/geom_subr.c:
	Add DDB command decoding for BIO_ZONE commands.

sys/kern/subr_devstat.c:
	Record statistics for REPORT ZONES commands.  Note that the
	number of bytes transferred for REPORT ZONES won't quite match
	what is received from the harware.  This is because we're
	necessarily counting bytes coming from the da(4) / ada(4) drivers,
	which are using the disk_zone.h interface to communicate up
	the stack.  The structure sizes it uses are slightly different
	than the SCSI and ATA structure sizes.

sys/sys/ata.h:
	Add many bit and structure definitions for ZAC, NCQ, and EPC
	command support.

sys/sys/bio.h:
	Convert the bio_cmd field to a straight enumeration.  This will
	yield more space for additional commands in the future.  After
	change r297955 and other related changes, this is now possible.
	Converting to an enumeration will also prevent use as a bitmask
	in the future.

sys/sys/disk.h:
	Define the DIOCZONECMD ioctl.

sys/sys/disk_zone.h:
	Add a new API for managing zoned disks.  This is very close to
	the SCSI ZBC and ATA ZAC standards, but uses integers in native
	byte order instead of big endian (SCSI) or little endian (ATA)
	byte arrays.

	This is intended to offer to the complete feature set of the ZBC
	and ZAC disk management without requiring the application developer
	to include SCSI or ATA headers.  We also use one set of headers
	for ioctl consumers and kernel bio-level consumers.

sys/sys/param.h:
	Bump __FreeBSD_version for sys/bio.h command changes, and inclusion
	of SMR support.

usr.sbin/Makefile:
	Add the zonectl utility.

usr.sbin/diskinfo/diskinfo.c
	Add disk zoning capability to the 'diskinfo -v' output.

usr.sbin/zonectl/Makefile:
	Add zonectl makefile.

usr.sbin/zonectl/zonectl.8
	zonectl(8) man page.

usr.sbin/zonectl/zonectl.c
	The zonectl(8) utility.  This allows managing SCSI or ATA zoned
	disks via the disk_zone.h API.  You can report zones, reset write
	pointers, get parameters, etc.

0e358df062 Revamp camcontrol(8) fwdownload support and add the opcodes subcommand.
The significant changes and bugs fixed here are:

1. Fixed a bug in the progress display code:

   When the user's filename is too big, or his terminal width is too
   small, the progress code could wind up using a negative number for
   the length of the "stars" that it uses to indicate progress.

   This negative value was assigned to an unsigned variable, resulting
   in a very large positive value.

   The result is that we wound up writing garbage from memory to the
   user's terminal.

   With an 80 column terminal, a file name length of more than 35
   characters would generate this problem.

   To address this, we now set a minimum progress bar length, and
   truncate the user's file name as needed.

   This has been tested with large filenames and small terminals, and
   at least produces reasonable results.  If the terminal is too
   narrow, the progress display takes up an additional line with each
   update, but this is more user friendly than writing garbage to the
   tty.

2. SATA drives connected via a SATA controller didn't have SCSI Inquiry
   data populated in struct cam_device.  This meant that the code in
   fw_get_vendor() in fwdownload.c would try to match a zero-length
   vendor ID, and so return the first entry in the vendor table.  (Which
   used to be HITACHI.)  Fixed by grabbing identify data, passing the
   identify buffer into fw_get_vendor(), and matching against the model
   name.

3. SATA drives connected via a SAS controller do have Inquiry data
   populated.  The table included a couple of entries -- "ATA ST" and
   "ATA HDS", intended to handle Seagate and Hitachi SATA drives attached
   via a SAS controller.  SCSI to ATA translation layers use a vendor
   ID of "ATA" (which is standard), and then the model name from the ATA
   identify data as the SCSI product name when they are returning data on
   SATA disks.  The cam_strmatch code will match the first part of the
   string (because the length it is given is the length of the vendor,
   "ATA"), and return 0 (i.e. a match).  So all SATA drives attached to
   a SAS controller would be programmed using the Seagate method
   (WRITE BUFFER mode 7) of SCSI firmware downloading.

4. Issue #2 above covered up a bug in fw_download_img() -- if the
   maximum packet size in the vendor table was 0, it tried to default
   to a packet size of 32K.  But then it didn't actually succeed in
   doing that, because it set the packet size to the value that was
   in the vendor table (0).  Now that we actually have ATA attached
   drives fall use the VENDOR_ATA case, we need a reasonable default
   packet size.  So this is fixed to properly set the default packet size.

5. Add support for downloading firmware to IBM LTO drives, and add a
   firmware file validation method to make sure that the firmware
   file matches the drive type.  IBM tape drives include a Load ID and
   RU name in their vendor-specific VPD page 0x3.  Those should match
   the IDs in the header of the firmware file to insure that the
   proper firmware file is loaded.

6. This also adds a new -q option to the camcontrol fwdownload
   subcommand to suppress informational output.  When -q is used in
   combination with -y, the firmware upgrade will happen without
   prompting and without output except if an error condition occurs.

7. Re-add support for printing out SCSI inquiry information when
   asking the user to confirm that they want to download firmware, and
   add printing of ATA Identify data if it is a SATA disk.  This was
   removed in r237281 when support for flashing ATA disks was added.

8. Add a new camcontrol(8) "opcodes" subcommand, and use the
   underlying code to get recommended timeout values for drive
   firmware downloads.

   Many SCSI devices support the REPORT SUPPORTED OPERATION CODES
   command, and some support the optional timeout descriptor that
   specifies nominal and recommended timeouts for the commands
   supported by the device.

   The new camcontrol opcodes subcommand allows displaying all
   opcodes supported by a drive, information about which fields
   in a SCSI CDB are actually used by a given SCSI device, and the
   nominal and recommended timeout values for each command.

   Since firmware downloads can take a long time in some devices, and
   the time varies greatly between different types of devices, take
   advantage of the infrastructure used by the camcontrol opcodes
   subcommand to determine the best timeout to use for the WRITE
   BUFFER command in SCSI device firmware downloads.

   If the device recommends a timeout, it is likely to be more
   accurate than the default 50 second timeout used by the firmware
   download code.  If the user specifies a timeout, it will override
   the default or device recommended timeout.  If the device doesn't
   support timeout descriptors, we fall back to the default.

9. Instead of downloading firmware to SATA drives behind a SAS controller
   using WRITE BUFFER, use the SCSI ATA PASS-THROUGH command to compose
   an ATA DOWNLOAD MICROCODE command and it to the drive.  The previous
   version of this code attempted to send a SCSI WRITE BUFFER command to
   SATA drives behind a SAS controller.  Although that is part of the
   SAT-3 spec, it doesn't work with the parameters used with LSI
   controllers at least.

10.Add a new mechanism for making common ATA passthrough and
   ATA-behind-SCSI passthrough commands.

   The existing camcontrol(8) ATA command mechanism checks the device
   type on every command executed.  That works fine for individual
   commands, but is cumbersome for things like a firmware download
   that send a number of commands.

   The fwdownload code detects the device type up front, and then
   sends the appropriate commands.

11.In simulation mode (-s), if the user specifies the -v flag, print out
   the SCSI CDB or ATA registers that would be sent to the drive.  This will
   aid in debugging any firmware download issues.

sbin/camcontrol/fwdownload.c:
	Add a device type to the fw_vendor structure, so that we can
	specify different download methods for different devices from the
	same vendor.  In this case, IBM hard drives (from when they
	still made hard drives) and tape drives.

	Add a tur_status field to the fw_vendor structure so that we can
	specify whether the drive to be upgraded should be ready, not
	ready, or whether it doesn't matter.  Add the corresponding
	capability in fw_download_img().

	Add comments describing each of the vendor table fields.

	Add HGST and SmrtStor to the supported SCSI vendors list.

	In fw_get_vendor(), look at ATA identify data if we have a SATA
	device to try to identify what the drive vendor is.

	Add IBM firmware file validation.  This gets VPD page 0x3, and
	compares the Load ID and RU name in the page to the values
	included in the header.  The validation code will refuse to load
	a firmware file if the values don't match.  This does allow the
	user to attempt a downgrade; whether or not it succeeds will
	likely depend on the drive settings.

	Add a -q option, and disable all informative output
	(progress bars, etc.) when this is enabled.

	Re-add the inquiry in the confirmation dialog so the user has
	a better idea of which device he is talking to.  Add support for
	displaying ATA identify data.

	Don't automatically disable confirmation in simulation (-s) mode.
	This allows the user to see the inquiry or identify data in the
	dialog, and see exactly what they would see when the command
	actually runs.  Also, in simulation mode, if the user specifies
	the -v flag, print out the SCSI CDB or ATA registers that would
	be sent to the drive.  This will aid in debugging any firmware
	download issues.

	Add a timeout field and timeout type to the firmware download
	vendor table.  This allows specifying a default timeout and allows
	specifying whether we should attempt to probe for a recommended
	timeout from the drive.

	Add a new fuction, fw_get_timeout(), that will determine
	which timeout to use for the WRITE BUFFER command.  If the
	user specifies a timeout, we always use that.  Otherwise,
	we will use the drive recommended timeout, if available,
	and fall back to the default when a drive recommended
	timeout isn't available.

	When we prompt the user, tell him what timeout we're going
	to use, and the source of the timeout.

	Revamp the way SATA devices are handled.

	In fwdownload(), use the new get_device_type() function to
	determine what kind of device we're talking to.

	Allow firmware downloads to any SATA device, but restrict
	SCSI downloads to known devices.  (The latter is not a
	change in behavior.)

	Break out the "ready" check from fw_download_img() into a
	new subfunction, fw_check_device_ready().  This sends the
	appropriate command to the device in question -- a TEST
	UNIT READY or an IDENTIFY.  The IDENTIFY for SATA devices
 	a SAT layer is done using the SCSI ATA PASS-THROUGH
	command.

	Use the new build_ata_cmd() function to build either a SCSI or
	ATA I/O CCB to issue the DOWNLOAD MICROCODE command to SATA
	devices.  build_ata_cmd() figures looks at the devtype argument
	and fills in the correct CCB type and CDB or ATA registers.

	Revamp the vendor table to remove the previous
	vendor-specific ATA entries and use a generic ATA vendor
	placeholder.  We currently use the same method for all ATA
	drives, although we may have to add vendor-specific
	behavior once we test this with more drives.

sbin/camcontrol/progress.c:
	In progress_draw(), make barlength a signed value so that
	we can easily detect a negative value.

	If barlength (the length of the progress bar) would wind up
	negative due to a small TTY width or a large filename,
	set the bar length to the new minimum (10 stars) and
	truncate the user's filename.  We will truncate it down to
	0 characters if necessary.

	Calculate a new prefix_len variable (user's filename length)
	and use it as the precision when printing the filename.

sbin/camcontrol/camcontrol.c:
	Implement a new camcontrol(8) subcommand, "opcodes".  The
	opcodes subcommand allows displaying the entire list of
	SCSI commands supported by a device, or details on an
	individual command.  In either case, it can display
	nominal and recommended timeout values.

	Add the scsiopcodes() function, which calls the new
	scsigetopcodes() function to fetch opcode data from a
	drive.

	Add two new functions, scsiprintoneopcode() and
	scsiprintopcodes(), which print information about one
	opcode or all opcodes, respectively.

	Remove the get_disk_type() function.  It is no longer used.

	Add a new function, dev_has_vpd_page(), that fetches the
	supported INQUIRY VPD list from a device and tells the
	caller whether the requested VPD page is available.

	Add a new function, get_device_type(), that returns a more
	precise device type than the old get_disk_type() function.
	The get_disk_type() function only distinguished between
	SCSI and ATA devices, and SATA devices behind a SCSI to ATA
	translation layer were considered to be "SCSI".

	get_device_type() offers a third type, CC_DT_ATA_BEHIND_SCSI.
	We need to know this to know whether to attempt to send ATA
	passthrough commands.  If the device has the ATA
	Information VPD page (0x89), then it is an ATA device
	behind a SCSI to ATA translation layer.

	Remove the type argument from the fwdownload() subcommand.

	Add a new function, build_ata_cmd(), that will take one set
	of common arguments and build either a SCSI or ATA I/O CCB,
	depending on the device type passed in.

sbin/camcontrol/camcontrol.h:
	Add a prototype for scsigetopcodes().

	Add a new enumeration, camcontrol_devtype.

	Add prototypes for dev_has_vpd_page(), get_device_type()
	and build_ata_cmd().

5672fac935 Add support for reading MAM attributes to camcontrol(8) and libcam(3).
MAM is Medium Auxiliary Memory and is most commonly found as flash
chips on tapes.

This includes support for reading attributes and decoding most
known attributes, but does not yet include support for writing
attributes or reporting attributes in XML format.

libsbuf/Makefile:
	Add subr_prf.c for the new sbuf_hexdump() function.  This
	function is essentially the same function.

libsbuf/Symbol.map:
	Add a new shared library minor version, and include the
	sbuf_hexdump() function.

libsbuf/Version.def:
	Add version 1.4 of the libsbuf library.

libutil/hexdump.3:
	Document sbuf_hexdump() alongside hexdump(3), since it is
	essentially the same function.

camcontrol/Makefile:
	Add attrib.c.

camcontrol/attrib.c:
	Implementation of READ ATTRIBUTE support for camcontrol(8).

camcontrol/camcontrol.8:
	Document the new 'camcontrol attrib' subcommand.

camcontrol/camcontrol.c:
	Add the new 'camcontrol attrib' subcommand.

camcontrol/camcontrol.h:
	Add a function prototype for scsiattrib().

share/man/man9/sbuf.9:
	Document the existence of sbuf_hexdump() and point users to
	the hexdump(3) man page for more details.

sys/cam/scsi/scsi_all.c:
	Add a table of known attributes, text descriptions and
	handler functions.

	Add a new scsi_attrib_sbuf() function along with a number
	of other related functions that help decode attributes.

	scsi_attrib_ascii_sbuf() decodes ASCII format attributes.

	scsi_attrib_int_sbuf() decodes binary format attributes, and
	will pass them off to scsi_attrib_hexdump_sbuf() if they're
	bigger than 8 bytes.

	scsi_attrib_vendser_sbuf() decodes the vendor and drive
	serial number attribute.

	scsi_attrib_volcoh_sbuf() decodes the Volume Coherency
	Information attribute that LTFS writes out.

sys/cam/scsi/scsi_all.h:
	Add a number of attribute-related structure definitions and
	other defines.

	Add function prototypes for all of the functions added in
	scsi_all.c.

sys/kern/subr_prf.c:
	Add a new function, sbuf_hexdump().  This is the same as
	the existing hexdump(9) function, except that it puts the
	result in an sbuf.

	This also changes subr_prf.c so that it can be compiled in
	userland for includsion in libsbuf.

	We should work to change this so that the kernel hexdump
	implementation is a wrapper around sbuf_hexdump() with a
	statically allocated sbuf with a drain.  That will require
	a drain function that goes to the kernel printf() buffer
	that can take a non-NUL terminated string as input.
	That is because an sbuf isn't NUL-terminated until it is
	finished, and we don't want to finish it while we're still
	using it.

	We should also work to consolidate the userland hexdump and
	kernel hexdump implemenatations, which are currently
	separate.  This would also mean making applications that
	currently link in libutil link in libsbuf.

sys/sys/sbuf.h:
	Add the prototype for sbuf_hexdump(), and add another copy
	of the hexdump flag values if they aren't already defined.

	Ideally the flags should be defined in one place but the
	implemenation makes it difficult to do properly.  (See
	above.)

08df2e3eaf Add persistent reservation support to camcontrol(8).
camcontrol(8) now supports a new 'persist' subcommand that allows users to
issue SCSI PERSISTENT RESERVE IN / OUT commands.

sbin/camcontrol/Makefile:
	Add persist.c.

sbin/camcontrol/persist.c:
	New persistent reservation support for camcontrol(8).

	We have support for all known operation modes for PERSISTENT RESERVE
	IN and PERSISTENT RESERVE OUT.
	exceptions noted above.

sbin/camcontrol/camcontrol.8:
	Document the new 'persist' subcommand.

	In the section on the Transport ID (-I) option, explain what
	Transport IDs for each protocol should look like.  At some point
	some of this information could probably get moved off in a
	separate man page, either on Transport IDs alone or a man page
	documenting the Transport ID parsing code.

	Add a number of examples of persistent reservation commands.
	Persistent Reservations are complex enough that the average user
	probably won't be able to get the commands exactly right by just
	reading the man page.  These examples show a few basic and
	advanced examples of how to use persistent reservations.

sbin/camcontrol/camcontrol.h:
	Move the definition for camcontrol_optret here, so we can use it
	for the persistent reservation code.

	Add a definition for the new scsipersist() function.

sbin/camcontrol/camcontrol.c:
	Add 'persist' to the list of subcommands.

	Document 'persist' in the help text.

sys/cam/scsi/scsi_all.c:
	Add the scsi_persistent_reserve_in() and
	scsi_persistent_reserve_out() CCB building functions.

	Add a new function, scsi_transportid_sbuf().  This takes a
	SCSI Transport ID (documented in SPC-4), and prints it to
	an sbuf(9).  There are some transports (like ATA, USB, and
	SSA) for which there is no transport defined.  We need to
	come up with a reasonable thing to do if we're presented
	with a Transport ID that claims to be for one of those
	protocols.

	Add new routines scsi_get_nv() and scsi_nv_to_str().

	These functions do a table lookup to go between a string and an
	integer.  There are lots of table lookups needed in the
	persistent reservation code in camcontrol(8).

	Add a new function, scsi_parse_transportid(), along with leaf node
	functions to parse:
	FC, 1394 and SAS (scsi_parse_transportid_64bit())
	iSCSI (scsi_parse_transportid_iscsi())
	SPI (scsi_parse_transportid_spi())
	RDMA (scsi_parse_transportid_rdma())
	PCIe (scsi_parse_transportid_sop())

	Transport IDs.  Given a string with the general form proto,id these
	functions create a SCSI Transport ID structure.

sys/cam/scsi/scsi_all.h:
	Update the various persistent reservation data structures to
	SPC4r36l, but also rename some fields that were previously
	obsolete with the proper names from older SCSI specs.  This
	allows using older, obsolete persistent reservation types when
	desired.

	Add function prototypes for the new persistent reservation CCB
	building functions.

	Add a data strucure for the READ FULL STATUS service action
	of the PERSISTENT RESERVE IN command.

	Add Transport ID structures for all protocols described in SPC-4.

	Add a new series of SCSI_PROTO_XXX definitions, and
	redefine other defines in terms of these new definitions.

	Add a prototype for scsi_transportid_sbuf().

	Change a couple of "obsolete" persistent reservation data
	structure fields into something more meaningful, based on
	what the field was called when it was defined in the spec.
	(e.g. SPC, SPC-2, etc.)

	Create a new define, SPRI_MAX_LEN, for the maximum allocation
	length allowed for the PERSISTENT RESERVE IN command.

	Add data structures and enumerations for the new name/value
	translation functions.

	Add data structures for SCSI over PCIe Routing IDs.

	Bring the PERSISTENT RESERVE OUT Register and Move parameter list
	structure (struct scsi_per_res_out_parms) up to date with SPC-4.

	Add a data structure for the transport IDs that can optionally be
	appended to the basic PERSISTENT RESERVE OUT parameter list.

	Move SCSI protocol macro definitions out of the VPD page 0x83
	definition and combine them with the more up to date protocol
	definitions higher in the file.

	Add function prototypes for scsi_nv_to_str(), scsi_get_nv(),
	scsi_parse_transportid_64bit(), scsi_parse_transportid_spi(),
	scsi_parse_transportid_rdma(), scsi_parse_transportid_iscsi(),
	scsi_parse_transportid_sop(), and scsi_parse_transportid().

1f4782a4c1 Add firmware update support for SCSI devices.
Firmware can be reprogrammed on devices from Hitachi, HP, IBM, Plextor,
Quantum, and Seagate.  At least one device from each manufacturer has
been tested with some version of this code, and it has been used to
update thousands of drives so far.

The man page suggests having a backup of the drive's data, and the
operation must be confirmed, either interactively or on the command
line.  (This is the same as the confirmation on the format command.)

This work is largely derived from fwprog.c by Andre Albsmeier.

7e32b20d95 This is an overhaul of the mode page handling in camcontrol as well as
related patches. These include:
	* Mode page editting can be scripted. This involves two
	  things: first, if stdin is not a tty, changes are read from
	  stdin rather than invoking $EDITOR. Second, and more
	  importantly, not all modepage entries must be included in the
	  change set. This means that camcontrol can now gracefully handle
	  more intrusive editting from the $EDITOR, including removal or
	  rearrangement of lines. It also means that you can do stuff
	  like:
		# echo "WCE: 1" | camcontrol modepage da3 -m 8 -e
		# newfs /dev/da3
		# echo "WCE: 0" | camcontrol modepage da3 -m 8 -e
	* Range-checking on user-supplied input values. modeedit.c now
	  uses the field width specifiers to determine the maximum
	  allowable value for a field. If the user enters a value larger
	  than the maximum, it clips the value to the max and warns the
	  user. This also involved patching cam_cmdparse.c to be more
	  consistent with regards to the "count" parameter to arg_put
	  (previously is was the length of strings and 1 for all integral
	  types). The cam_cdbparse(3) man page was also updated to reflect
	  the revised semantics.
	* In the process, I removed the 64 entry limit on mode pages (not
	  that we were even close to hitting that limit). This was a nice
	  side-effect of the other changes.
	* Technically, the new mode editting functionality allows editting
	  of character array entries in mode pages (type 'c' or 'z'),
	  however since buff_encode doesn't grok them it is currently
	  useless.
	* Camcontrol gained two new options related to mode pages: -l and
	  -b. The former lists all available mode pages for a given
	  device. The latter forces mode page display in binary format
	  (the default when no mode page definition was found in
	  scsi_modes).
	* Added support for mode page names to scsi_modes. Allows names to
	  be displayed alongside mode numbers in the mode page
	  listing. Updated scsi_modes to use the new functionality. This
	  also adds the semicolon into the scsi_modes syntax as an
	  optional mode page definition terminator. This is needed to name
	  pages without providing a page format definition.
	* Updated scsi_all.h to include a structure describing mode page
	  headers.
	* Added $FreeBSD$ line to scsi_modes.

c60e19a83b Add a new device specification syntax to camcontrol. It is now possible to
do things like:

camcontrol tur da5
or
camcontrol tur 1:2:0
or
camcontrol tur 1:2

These changes are fully backwards compatible with the original device
specification syntax (-n dev -u unit), so it is possible to use either
method to specify a device now.

The device specification changes do not affect the rescan, reset or debug
commands, since by design, those commands work on a bus or bus:target:lun
basis only.

Also, shorten the default usage statement so that it fits in a 24 column
terminal.  The full usage statement is still available by using the "help"
"-h" or "-?" arguments to camcontrol.
