#define _CAMCONTROL_H

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().

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().
Remove the type argument from the fwdownload() subcommand.
sbin/camcontrol/camcontrol.8
Explain that the fwdownload subcommand will use the drive
recommended timeout if available, and that the user can
override the timeout.
Document the new opcodes subcommand.
Explain that we will attempt to download firmware to any
SATA device.
Document supported SCSI vendors, and models tested if known.
Explain the commands used to download firmware for the
three different drive and controller combinations.
Document that the -v flag in simulation mode for the fwdownload
subcommand will print out the SCSI CDBs or ATA registers that would
be used.
sys/cam/scsi/scsi_all.h:
Add new bit definitions for the one opcode descriptor for
the REPORT SUPPORTED OPCODES command.
Add a function prototype for scsi_report_supported_opcodes().
sys/cam/scsi/scsi_all.c:
Add a new CDB building function, scsi_report_supported_opcodes().

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().
Remove the type argument from the fwdownload() subcommand.
sbin/camcontrol/camcontrol.8
Explain that the fwdownload subcommand will use the drive
recommended timeout if available, and that the user can
override the timeout.
Document the new opcodes subcommand.
Explain that we will attempt to download firmware to any
SATA device.
Document supported SCSI vendors, and models tested if known.
Explain the commands used to download firmware for the
three different drive and controller combinations.
Document that the -v flag in simulation mode for the fwdownload
subcommand will print out the SCSI CDBs or ATA registers that would
be used.
sys/cam/scsi/scsi_all.h:
Add new bit definitions for the one opcode descriptor for
the REPORT SUPPORTED OPCODES command.
Add a function prototype for scsi_report_supported_opcodes().
sys/cam/scsi/scsi_all.c:
Add a new CDB building function, scsi_report_supported_opcodes().

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().
Remove the type argument from the fwdownload() subcommand.
sbin/camcontrol/camcontrol.8
Explain that the fwdownload subcommand will use the drive
recommended timeout if available, and that the user can
override the timeout.
Document the new opcodes subcommand.
Explain that we will attempt to download firmware to any
SATA device.
Document supported SCSI vendors, and models tested if known.
Explain the commands used to download firmware for the
three different drive and controller combinations.
Document that the -v flag in simulation mode for the fwdownload
subcommand will print out the SCSI CDBs or ATA registers that would
be used.
sys/cam/scsi/scsi_all.h:
Add new bit definitions for the one opcode descriptor for
the REPORT SUPPORTED OPCODES command.
Add a function prototype for scsi_report_supported_opcodes().
sys/cam/scsi/scsi_all.c:
Add a new CDB building function, scsi_report_supported_opcodes().

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().

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.)
