Significant upgrades to sa(4) and mt(1).
The primary focus of these changes is to modernize FreeBSD's
tape infrastructure so that we can take advantage of some of the
features of modern tape drives and allow support for LTFS.
Significant changes and new features include:
o sa(4) driver status and parameter information is now exported via an
XML structure. This will allow for changes and improvements later
on that will not break userland applications. The old MTIOCGET
status ioctl remains, so applications using the existing interface
will not break.
o 'mt status' now reports drive-reported tape position information
as well as the previously available calculated tape position
information. These numbers will be different at times, because
the drive-reported block numbers are relative to BOP (Beginning
of Partition), but the block numbers calculated previously via
sa(4) (and still provided) are relative to the last filemark.
Both numbers are now provided. 'mt status' now also shows the
drive INQUIRY information, serial number and any position flags
(BOP, EOT, etc.) provided with the tape position information.
'mt status -v' adds information on the maximum possible I/O size,
and the underlying values used to calculate it.
o The extra sa(4) /dev entries (/dev/saN.[0-3]) have been removed.
The extra devices were originally added as place holders for
density-specific device nodes. Some OSes (NetBSD, NetApp's OnTap
and Solaris) have had device nodes that, when you write to them,
will automatically select a given density for particular tape drives.
This is a convenient way of switching densities, but it was never
implemented in FreeBSD. Only the device nodes were there, and that
sometimes confused users.
For modern tape devices, the density is generally not selectable
(e.g. with LTO) or defaults to the highest availble density when
the tape is rewritten from BOT (e.g. TS11X0). So, for most users,
density selection won't be necessary. If they do need to select
the density, it is easy enough to use 'mt density' to change it.
o Protection information is now supported. This is either a
Reed-Solomon CRC or CRC32 that is included at the end of each block
read and written. On write, the tape drive verifies the CRC, and
on read, the tape drive provides a CRC for the userland application
to verify.
o New, extensible tape driver parameter get/set interface.
o Density reporting information. For drives that support it,
'mt getdensity' will show detailed information on what formats the
tape drive supports, and what formats the tape drive supports.
o Some mt(1) functionality moved into a new mt(3) library so that
external applications can reuse the code.
o The new mt(3) library includes helper routines to aid in parsing
the XML output of the sa(4) driver, and build a tree of driver
metadata.
o Support for the MTLOAD (load a tape in the drive) and MTWEOFI
(write filemark immediate) ioctls needed by IBM's LTFS
implementation.
o Improve device departure behavior for the sa(4) driver. The previous
implementation led to hangs when the device was open.
o This has been tested on the following types of drives:
IBM TS1150
IBM TS1140
IBM LTO-6
IBM LTO-5
HP LTO-2
Seagate DDS-4
Quantum DLT-4000
Exabyte 8505

lib/Makefile,
Add libmt.
lib/libmt/Makefile,
lib/libmt/mt.3,
lib/libmt/mtlib.c,
lib/libmt/mtlib.h,
New mt(3) library that contains functions moved from mt(1) and
new functions needed to interact with the updated sa(4) driver.
This includes XML parser helper functions that application writers
can use when writing code to query tape parameters.
rescue/rescue/Makefile:
Add -lmt to CRUNCH_LIBS.
src/share/man/man4/mtio.4
Clarify this man page a bit, and since it contains what is
essentially the mtio.h header file, add new ioctls and structure
definitions from mtio.h.
src/share/man/man4/sa.4
Update BUGS and maintainer section.
sys/cam/scsi/scsi_all.c,
sys/cam/scsi/scsi_all.h:
Add SCSI SECURITY PROTOCOL IN/OUT CDB definitions and CDB building
functions.
sys/cam/scsi/scsi_sa.c
sys/cam/scsi/scsi_sa.h
Many tape driver changes, largely outlined above.
Increase the sa(4) driver read/write timeout from 4 to 32
minutes. This is based on the recommended values for IBM LTO
5/6 drives. This may also avoid timeouts for other tape
hardware that can take a long time to do retries and error
recovery. Longer term, a better way to handle this is to ask
the drive for recommended timeout values using the REPORT
SUPPORTED OPCODES command. Modern IBM and Oracle tape drives
at least support that command, and it would allow for more
accurate timeout values.
Add XML status generation. This is done with a series of
macros to eliminate as much duplicate code as possible. The
new XML-based status values are reported through the new
MTIOCEXTGET ioctl.
Add XML driver parameter reporting, using the new MTIOCPARAMGET
ioctl.
Add a new driver parameter setting interface, using the new
MTIOCPARAMSET and MTIOCSETLIST ioctls.
Add a new MTIOCRBLIM ioctl to get block limits information.
Add CCB/CDB building routines scsi_locate_16, scsi_locate_10,
and scsi_read_position_10().
scsi_locate_10 implements the LOCATE command, as does the
existing scsi_set_position() command. It just supports
additional arguments and features. If/when we figure out a
good way to provide backward compatibility for older
applications using the old function API, we can just revamp
scsi_set_position(). The same goes for
scsi_read_position_10() and the existing scsi_read_position()
function.
Revamp sasetpos() to take the new mtlocate structure as an
argument. It now will use either scsi_locate_10() or
scsi_locate_16(), depending upon the arguments the user
supplies. As before, once we change position we don't have a
clear idea of what the current logical position of the tape
drive is.
For tape drives that support long form position data, we
read the current position and store that for later reporting
after changing the position. This should help applications
like Bacula speed tape access under FreeBSD once they are
modified to support the new ioctls.
Add a new quirk, SA_QUIRK_NO_LONG_POS, that is set for all
drives that report SCSI-2 or older, as well as drives that
report an Illegal Request type error for READ POSITION with
the long format. So we should automatically detect drives
that don't support the long form and stop asking for it after
an initial try.
Add a partition number to the sa(4) softc.
Improve device departure handling. The previous implementation
led to hangs when the device was open.
If an application had the sa(4) driver open, and attempted to
close it after it went away, the cam_periph_release() call in
saclose() would cause the periph to get destroyed because that
was the last reference to it. Because destroy_dev() was
called from the sa(4) driver's cleanup routine (sacleanup()),
and would block waiting for the close to happen, a deadlock
would result.
So instead of calling destroy_dev() from the cleanup routine,
call destroy_dev_sched_cb() from saoninvalidate() and wait for
the callback.
Acquire a reference for devfs in saregister(), and release it
in the new sadevgonecb() routine when all devfs devices for
the particular sa(4) driver instance are gone.
Add a new function, sasetupdev(), to centralize setting
per-instance devfs device parameters instead of repeating the
code in saregister().
Add an open count to the softc, so we know how many
peripheral driver references are a result of open
sessions.
Add the D_TRACKCLOSE flag to the cdevsw flags so
that we get a 1:1 mapping of open to close calls
instead of a N:1 mapping.
This should be a no-op for everything except the
control device, since we don't allow more than one
open on non-control devices.
However, since we do allow multiple opens on the
control device, the combination of the open count
and the D_TRACKCLOSE flag should result in an
accurate peripheral driver reference count, and an
accurate open count.
The accurate open count allows us to release all
peripheral driver references that are the result
of open contexts once we get the callback from devfs.
sys/sys/mtio.h:
Add a number of new mt(4) ioctls and the requisite data
structures. None of the existing interfaces been removed
or changed.
This includes definitions for the following new ioctls:
MTIOCRBLIM /* get block limits */
MTIOCEXTLOCATE /* seek to position */
MTIOCEXTGET /* get tape status */
MTIOCPARAMGET /* get tape params */
MTIOCPARAMSET /* set tape params */
MTIOCSETLIST /* set N params */
usr.bin/mt/Makefile:
mt(1) now depends on libmt, libsbuf and libbsdxml.
usr.bin/mt/mt.1:
Document new mt(1) features and subcommands.
usr.bin/mt/mt.c:
Implement support for mt(1) subcommands that need to
use getopt(3) for their arguments.
Implement a new 'mt status' command to replace the old
'mt status' command. The old status command has been
renamed 'ostatus'.
The new status function uses the MTIOCEXTGET ioctl, and
therefore parses the XML data to determine drive status.
The -x argument to 'mt status' allows the user to dump out
the raw XML reported by the kernel.
The new status display is mostly the same as the old status
display, except that it doesn't print the redundant density
mode information, and it does print the current partition
number and position flags.
Add a new command, 'mt locate', that will supersede the
old 'mt setspos' and 'mt sethpos' commands. 'mt locate'
implements all of the functionality of the MTIOCEXTLOCATE
ioctl, and allows the user to change the logical position
of the tape drive in a number of ways. (Partition,
block number, file number, set mark number, end of data.)
The immediate bit and the explicit address bits are
implemented, but not documented in the man page.
Add a new 'mt weofi' command to use the new MTWEOFI ioctl.
This allows the user to ask the drive to write a filemark
without waiting around for the operation to complete.
Add a new 'mt getdensity' command that gets the XML-based
tape drive density report from the sa(4) driver and displays
it. This uses the SCSI REPORT DENSITY SUPPORT command
to get comprehensive information from the tape drive about
what formats it is able to read and write.
Add a new 'mt protect' command that allows getting and setting
tape drive protection information. The protection information
is a CRC tacked on to the end of every read/write from and to
the tape drive.

Change the sa(4) driver to check for long position support on
SCSI-2 devices.
Some older tape devices claim to be SCSI-2, but actually do support
long position information. (Long position information includes
the current file mark.) For example, the COMPAQ SuperDLT1.
So we now only disable the check on SCSI-1 and older devices.
sys/cam/scsi/scsi_sa.c:
In saregister(), only disable fetching long position
information on SCSI-1 and older drives. Update the
comment to explain why.

Fix a couple of problems in the sa(4) media type reports.
The only drives I have discovered so far that support medium type
reports are newer HP LTO (LTO-5 and LTO-6) drives. IBM drives
only support the density reports.
sys/cam/scsi/scsi_sa.h:
The number of possible density codes in the medium type
report is 9, not 8. This caused problems parsing all of
the medium type report after this point in the structure.
usr.bin/mt/mt.c:
Run the density codes returned in the medium type report
through denstostring(), just like the primary and secondary
density codes in the density report. This will print the
density code in hex, and give a text description if it
is available.
Thanks to Rudolf Cejka for doing extensive testing with HP LTO drives
and Bacula and discovering these problems.

Improve the mt(1) rblim display.
The granularity reported by READ BLOCK LIMITS is an exponent, not a
byte value. So a granularity of 0 means 2^0, or 1 byte. A
granularity of 1 means 2^1, or 2 bytes.
Print out the individual block limits on separate lines to improve
readability and avoid exceeding 80 columns.
usr.bin/mt/mt.c:
Fix and improve the 'mt rblim' output. Add a MT_PLURAL()
macro so we can print "byte" or "bytes" as appropriate.

.Sh DESCRIPTION
|
||||||
|
The MT library consists of a number of functions designed to aid in
|
||||||
|
interacting with the
|
||||||
|
.Xr sa 4
|
||||||
|
driver.
|
||||||
|
The
|
||||||
|
.Xr sa 4
|
||||||
|
driver returns some status data as XML-formatted strings, and
|
||||||
|
the primary purpose of this library is to make it easier for the
|
||||||
|
software developer to parse those strings and extract the status values.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Fn mt_start_element ,
|
||||||
|
.Fn mt_end_element ,
|
||||||
|
and
|
||||||
|
.Fn mt_char_handler
|
||||||
|
functions are designed to work with the
|
||||||
|
.Xr libbbsdxml 3
|
||||||
|
library, which is an XML parsing library.
|
||||||
|
The user data for the XML parser should be set with
|
||||||
|
.Fn XML_SetUserData
|
||||||
|
to a zeroed struct
|
||||||
|
mt_status_data with the entries list initialized.
|
||||||
|
The element handlers for the XML parser should be set to
|
||||||
|
.Fn mt_start_element
|
||||||
|
and
|
||||||
|
.Fn mt_end_element
|
||||||
|
with
|
||||||
|
.Fn XML_SetElementHandler .
|
||||||
|
The character data handler should be set to
|
||||||
|
.Fn mt_char_handler
|
||||||
|
with the
|
||||||
|
.Fn XML_SetCharacterDataHandler
|
||||||
|
function.
|
||||||
|
The error member of the status_data structure will be set to 0 if parsing
|
||||||
|
is successful, and non-zero if parsing failed.
|
||||||
|
In the event of a failure, the error_str member will contain an error
|
||||||
|
message describing the failure.
|
||||||
|
These functions will build a tree of tape driver status data that can be
|
||||||
|
searched and printed using the other functions in this library.
|
||||||
|
.Pp
|
||||||
|
.Fn mt_status_tree_sbuf
|
||||||
|
takes the root node of a tree of
|
||||||
|
.Xr sa 4
|
||||||
|
driver status information, and displays it in an
|
||||||
|
.Xr sbuf 9 .
|
||||||
|
The
|
||||||
|
.Ar sb
|
||||||
|
argument is the destination sbuf.
|
||||||
|
The
|
||||||
|
.Ar entry
|
||||||
|
argument is the root of the tree.
|
||||||
|
The
|
||||||
|
.Ar indent
|
||||||
|
argument is the number of characters to indent the output.
|
||||||
|
Each recursive call to
|
||||||
|
.Fn mt_status_tree_sbuf
|
||||||
|
will have the indent level incremented by 2.
|
||||||
|
The
|
||||||
|
.Ar sbuf_func
|
||||||
|
argument is for a user-supplied alternate printing function.
|
||||||
|
If it is non-NULL, it will be called instead of the default output printing
|
||||||
|
code.
|
||||||
|
The
|
||||||
|
.Ar arg
|
||||||
|
argument is an argument for the
|
||||||
|
.Ar sbuf_func
|
||||||
|
function.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Fn mt_status_tree_print
|
||||||
|
function is the same as the
|
||||||
|
.Fn mt_status_tree_sbuf
|
||||||
|
function, except that the tree is printed to standard out instead of to a
|
||||||
|
sbuf.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Fn mt_entry_find
|
||||||
|
function returns the first entry in the tree starting at
|
||||||
|
.Ar entry
|
||||||
|
that matches
|
||||||
|
.Ar name .
|
||||||
|
The supplied node name can be a single level name like "foo", or it can
|
||||||
|
specify mulitple node names that must be matched, for instance "foo.bar.baz".
|
||||||
|
In the case of a single level name, it will match any node beneath
|
||||||
|
.Ar entry
|
||||||
|
that matches
|
||||||
|
.Ar name .
|
||||||
|
In the case of a multi-level name like "foo.bar.baz", it will return the
|
||||||
|
first entry named "baz" whose immediate parent is "bar" and where the
|
||||||
|
parent of "bar" is named "foo".
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Fn mt_status_entry_find
|
||||||
|
is the same as
|
||||||
|
.Fn mt_entry_find ,
|
||||||
|
except that it operates on the top level mt_status_data and all
|
||||||
|
mt_status_entry nodes below it instead of just an mt_status_entry
|
||||||
|
structure.
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Fn mt_status_entry_free
|
||||||
|
function frees the tree of status data underneath
|
||||||
|
.Ar entry .
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Fn mt_status_free
|
||||||
|
function frees the tree of status data underneath
|
||||||
|
.Ar status_data .
|
||||||
|
.Pp
|
||||||
|
The
|
||||||
|
.Fn mt_entry_sbuf
|
||||||
|
function prints
|
||||||
|
.Ar entry
|
||||||
|
to the supplied sbuf
|
||||||
|
.Ar sb ,
|
||||||
|
optionally using the
|
||||||
|
.Xr printf 3
|
||||||
|
format
|
||||||
|
.Ar fmt .
|
||||||
|
If
|
||||||
|
.Ar fmt
|
||||||
|
is NULL, then
|
||||||
|
.Fn mt_entry_sbuf
|
||||||
|
will render integer types in base 10 without special formatting and all
|
||||||
|
other types as they were rendered in the XML.
|
||||||
|
.Pp
|
||||||
|
.Fn mt_param_parent_sbuf
|
||||||
|
prints the parents of the given
|
||||||
|
.Ar entry
|
||||||
|
to the supplied sbuf
|
||||||
|
.Ar sb
|
||||||
|
subject to the print parameters
|
||||||
|
.Ar print_params .
|
||||||
|
The result will be formatted with a period between each level, like
|
||||||
|
"foo.bar.baz".
|
||||||
|
.Pp
|
||||||
|
.Fn mt_param_parent_print
|
||||||
|
is like
|
||||||
|
.Fn mt_param_parent_sbuf
|
||||||
|
except that it prints the results to standard output instead of an sbuf.
|
||||||
|
.Pp
|
||||||
|
.Fn mt_param_entry_sbuf
|
||||||
|
prints the
|
||||||
|
.Ar entry
|
||||||
|
to the given sbuf
|
||||||
|
.Ar sb .
|
||||||
|
The argument
|
||||||
|
.Ar arg
|
||||||
|
is a pointer to struct mt_print_params, which allows the caller to control
|
||||||
|
the printing output.
|
||||||
|
This function is intended to be supplied as an argument to
|
||||||
|
.Fn mt_status_tree_sbuf .
|
||||||
|
.Pp
|
||||||
|
.Fn mt_param_entry_print
|
||||||
|
is like
|
||||||
|
.Fn mt_param_entry_sbuf
|
||||||
|
except that it prints to standard output instead of an sbuf.
|
||||||
|
It is intended to be used as an argument to
|
||||||
|
.Fn mt_status_tree_print .
|
||||||
|
.Pp
|
||||||
|
.Fn mt_protect_print
|
||||||
|
prints tape drive protection information from the supplied
|
||||||
|
.Ar status_data
|
||||||
|
beginning at the node name defined as the root node for protection data.
|
||||||
|
If the
|
||||||
|
.Ar verbose
|
||||||
|
argument is non-zero, protection entry descriptions will be printed.
|
||||||
|
If it is zero, protection entry descriptions will not be printed.
|
||||||
|
.Pp
|
||||||
|
.Fn mt_param_list
|
||||||
|
prints tape driver parameters information from the supplied
|
||||||
|
.Ar status_data .
|
||||||
|
If the
|
||||||
|
.Ar param_name
|
||||||
|
is non-NULL, only the named parameter will be printed.
|
||||||
|
If
|
||||||
|
.Ar quiet
|
||||||
|
is non-zero, parameter descriptions will be omitted in the output.
|
||||||
|
.Pp
|
||||||
|
.Fn mt_density_name
|
||||||
|
Returns a text identifier for the supplied numeric
|
||||||
|
.Ar density_num .
|
||||||
|
The
|
||||||
|
.Ar density_num
|
||||||
|
should currently be a value between 0 and 255 inclusive, since that is the
|
||||||
|
valid range for
|
||||||
|
.Tn SCSI
|
||||||
|
density code values.
|
||||||
|
See below for notes on the return values.
|
||||||
|
.Pp
|
||||||
|
.Fn mt_density_bp
|
||||||
|
Returns the bits per inch or bits per mm values for a given density entry
|
||||||
|
specified by the
|
||||||
|
.Ar density_num .
|
||||||
|
If the
|
||||||
|
.Ar bpi
|
||||||
|
argument is non-zero, the bits per inch value is returned.
|
||||||
|
Otherwise, the bits per mm value is returned.
|
||||||
|
.Pp
|
||||||
|
.Fn mt_density_num
|
||||||
|
returns a numeric value for a text density description.
|
||||||
|
It does a case-insensitive comparison of density names in the density table
|
||||||
|
to the supplied density name.
|
||||||
|
.Pp
|
||||||
|
.Fn mt_get_xml_str
|
||||||
|
gets the current XML status / parameter string from the sa(4) driver
|
||||||
|
instance referenced by the open file descriptor
|
||||||
|
.Ar mtfd .
|
||||||
|
The
|
||||||
|
.Xr mtio 4
|
||||||
|
.Xr ioctl 2
|
||||||
|
to be used is supplied as the
|
||||||
|
.Ar cmd
|
||||||
|
argument.
|
||||||
|
Currently the
|
||||||
|
.Fn mt_get_xml_str
|
||||||
|
function will work with the
|
||||||
|
.Dv MTIOCEXTGET
|
||||||
|
and
|
||||||
|
.Dv MTIOCPARAMGET
|
||||||
|
ioctls.
|
||||||
|
The supplied
|
||||||
|
.Ar xml_str
|
||||||
|
will be filled in with a pointer to the complete XML status string.
|
||||||
|
Multiple calls to the given
|
||||||
|
.Xr ioctl 2
|
||||||
|
are made and more space is malloced until all of the XML string is fetched.
|
||||||
|
The string returned in the
|
||||||
|
.Ar xml_str
|
||||||
|
argument should be freed when it is no longer in use.
|
||||||
|
.Sh RETURN VALUES
|
||||||
|
.Fn mt_entry_find
|
||||||
|
returns the first matching entry, or NULL if it fails to find a match.
|
||||||
