75ec24dd53 Create libefivar library. This library aims to provide
the same API as the GPL'd version of this library. It implements the common
Linux API for programatically manipulating UEFI environment varibales using
the UEFI Runtime Services the kernel provides. It replaces the old efi
library since it is programmed to a different interface, but retails the
CHAR16 to UTF-8 and vice versa conversion routines. The new name is to match
Linux program's expectations.

8d7183939e Add librss, a simple wrapper around RSS APIs so applications can begin auto-tuning.
I've used this in a handful of RSS test applications.  It is just some
very simple functions to fetch the RSS configuration, query the per-bucket
CPU set, and mark sockets as local to an RSS bucket.  It should be sufficient
for both thread-based and process-based workloads.

(Yes, I wrote a manpage.)

This is based on some early RSS API and wrapper API work I did whilst
I was at Netflix.  Thanks to Netflix for the very original work that
spawned this; thanks to Peter Grehan for his feedback about RSS APIs
and thanks to Jack Vogel and Navdeep Parhar for the NIC-facing side of the
APIs.  These fed into the simple userland API I wrote up here.

a5e10af8bc Add libifc, a library implementing core functionality that exists in ifconfig(8) today.
libifc (pronounced lib-ifconfig) aims to be a light abstraction layer between
programs and the kernel APIs for managing the network configuration.
This should hopefully make programs easier to maintain, and reduce code
duplication.

Work will begin on making ifconfig(8) use this library in the near future.

This code is still evolving. The interface should not be considered stable until
it is announced as such.

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c
	Fix the resource.fs.zfs.statechange message. It had a number of
	problems:

	It was only being emitted on a transition to the HEALTHY state.
	That made it impossible for zfsd to take actions based on drives
	getting sicker.

	It compared the new state to vdev_prevstate, which is the state that
	the vdev had the last time it was opened.  That doesn't make sense,
	because a vdev can change state multiple times without being
	reopened.

	vdev_set_state contains logic that will change the device's new
	state based on various conditions.  However, the statechange event
	was being posted _before_ that logic took effect.  Now it's being
	posted after.

3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper

fea0add70e Start on a new library (libsysdecode) that provides routines for decoding
system call information such as system call arguments.  Initially this
will consist of pulling duplicated code out of truss and kdump though it
may prove useful for other utilities in the future.

This commit moves the shared utrace(2) record parser out of kdump into
the library and updates kdump and truss to use it.  One difference from
the previous version is that the library version treats unknown events
that start with the "RTLD" signature as unknown events.  This simplifies
the interface and allows the consumer to decide how to handle all
non-recognized events.  Instead, this function only generates a string
description for known malloc() and RTLD records.

d57ea329f6 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
	Sony DDS-2

contrib/groff/tmac/doc-syms,
share/mk/bsd.libnames.mk,
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.

5c13551143 Merge xz 5.2.0.
This brings support for multi-threaded compression.  This brings close
N times faster compression where N is the number of CPU cores.
Because of this, liblzma now depends on libthr.

Soon libarchive will be modified to use the new lzma API.

Thanks to antoine@ for the exp-run.
