6378393308 Add an internal libiscsiutil library.
Move some of the code duplicated between ctld(8) and iscsid(8) into a
libiscsiutil library.

Sharing the low-level PDU code did require having a
'struct connection' base class with a method table to permit separate
initiator vs target behavior (e.g. in handling proxy PDUs).

6aae3517ed Retire synchronous PPP kernel driver sppp(4).
The last two drivers that required sppp are cp(4) and ce(4).

These devices are still produced and can be purchased
at Cronyx <http://cronyx.ru/hardware/wan.html>.

Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no
longer support FreeBSD officially.  Later they have dropped
support for Linux drivers to.  As of mid-2020 they don't even
have a developer to maintain their Windows driver.  However,
their support verbally told me that they could provide aid to
a FreeBSD developer with documentaion in case if there appears
a new customer for their devices.

These drivers have a feature to not use sppp(4) and create an
interface, but instead expose the device as netgraph(4) node.
Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on
top of the node and get your synchronous PPP.  Alternatively
you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC.
Actually, last time I used cp(4) back in 2004, using netgraph(4)
instead of sppp(4) was already the right way to do.

Thus, remove the sppp(4) related part of the drivers and enable
by default the negraph(4) part.  Further maintenance of these
drivers in the tree shouldn't be a big deal.

While doing that, remove some cruft and enable cp(4) compilation
on amd64.  The ce(4) for some unknown reason marks its internal
DDK functions with __attribute__ fastcall, which most likely is
safe to remove, but without hardware I'm not going to do that, so
ce(4) remains i386-only.

e307eb94ae loader: zfs should support bootonce an nextboot
bootonce feature is temporary, one time boot, activated by
"bectl activate -t BE", "bectl activate -T BE" will reset the bootonce flag.

By default, the bootonce setting is reset on attempt to boot and the next
boot will use previously active BE.

By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will
be set permanently active.

bootonce dataset name is recorded in boot pool labels, bootenv area.

in case of nextboot, the nextboot_enable boolean variable is recorded in
freebsd:nvstore nvlist, also stored in boot pool label bootenv area.
On boot, the loader will process /boot/nextboot.conf if nextboot_enable
is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf
processing on next boot.

bootonce and nextboot features are usable in both UEFI and BIOS boot.

To use bootonce/nextboot features, the boot loader needs to be updated on disk;
if loader.efi is stored on ESP, then ESP needs to be updated and
for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated
(gpart or other tools).

At this time, only lua loader is updated.

fe815331bb build: provide a default WARNS for all in-tree builds
The current default is provided in various Makefile.inc in some top-level
directories and covers a good portion of the tree, but doesn't cover parts
of the build a little deeper (e.g. libcasper).

Provide a default in src.sys.mk and set WARNS to it in bsd.sys.mk if that
variable is defined. This lets us relatively cleanly provide a default WARNS
no matter where you're building in the src tree without breaking things
outside of the tree.

Crunchgen has been updated as a bootstrap tool to work on this change
because it needs r365605 at a minimum to succeed. The cleanup necessary to
successfully walk over this change on WITHOUT_CLEAN builds has been added.

There is a supplemental project to this to list all of the warnings that are
encountered when the environment has WARNS=6 NO_WERROR=yes:
https://warns.kevans.dev -- this project will hopefully eventually go away
in favor of CI doing a much better job than it.

9e5787d228 Merge OpenZFS support in to HEAD.
The primary benefit is maintaining a completely shared
code base with the community allowing FreeBSD to receive
new features sooner and with less effort.

I would advise against doing 'zpool upgrade'
or creating indispensable pools using new
features until this change has had a month+
to soak.

Work on merging FreeBSD support in to what was
at the time "ZFS on Linux" began in August 2018.
I first publicly proposed transitioning FreeBSD
to (new) OpenZFS on December 18th, 2018. FreeBSD
support in OpenZFS was finally completed in December
2019. A CFT for downstreaming OpenZFS support in
to FreeBSD was first issued on July 8th. All issues
that were reported have been addressed or, for
a couple of less critical matters there are
pull requests in progress with OpenZFS. iXsystems
has tested and dogfooded extensively internally.
The TrueNAS 12 release is based on OpenZFS with
some additional features that have not yet made
it upstream.

Improvements include:
  project quotas, encrypted datasets,
  allocation classes, vectorized raidz,
  vectorized checksums, various command line
  improvements, zstd compression.

Thanks to those who have helped along the way:
Ryan Moeller, Allan Jude, Zack Welch, and many
others.

94cba8034b Move ifconfig SFP status functionality into libifconfig
libifconfig_sfp.h provides an API in libifconfig for querying SFP module
properties, operational status, and vendor strings, as well as descriptions
of the various fields, string conversions, and other useful helpers for
implementing user interfaces.

SFP module status is obtained by reading registers via an I2C interface.
Descriptions of these registers and the values therein have been collected
in a Lua table which is used to generate all the boilerplace C headers and
source files for accessing these values, their names, and descriptions.
The generated code is fully commented and readable.

This is the first use of libifconfig in ifconfig itself.  For now, the
scope remains very limited.  Over time, more of ifconfig will be replaced
with libifconfig.

Some minor changes to the formatting of ifconfig output have been made:
- Module memory hex dumps are indented one extra space as a result of using
hexdump(3) instead of a bespoke hex dump function.
- Media descriptions have an added two-character short-name in parenthesis.
- QSFP modules were incorrectly displaying TX bias current as power.  Now
  TX channels display bias current, and this change has been made for both
  SFP and QSFP modules for consistency.

A Lua binding for libifconfig including this functionality is implemented
but has not been included in this commit.  The plan is for it to be
committed after dynamic module loading has been enabled in flua.

a7dc31283a Remove the NATM framework including the en(4), fatm(4), hatm(4), and
patm(4) devices.

Maintaining an address family and framework has real costs when we make
infrastructure improvements.  In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).

With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.

Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021.  Improvements to the code in FreeBSD 11 are
certainly welcome.

- Add a kvaddr_type to represent kernel virtual addresses instead of
  unsigned long.
- Add a struct kvm_nlist which is a stripped down version of struct nlist
  that uses kvaddr_t for n_value.
- Add a kvm_native() routine that returns true if an open kvm descriptor
  is for a native kernel and memory image.
- Add a kvm_open2() function similar to kvm_openfiles().  It drops the
  unused 'swapfile' argument and adds a new function pointer argument for
  a symbol resolving function.  Native kernels still use _fdnlist() from
  libc to resolve symbols if a resolver function is not supplied, but cross
  kernels require a resolver.
- Add a kvm_nlist2() function similar to kvm_nlist() except that it uses
  struct kvm_nlist instead of struct nlist.
- Add a kvm_read2() function similar to kvm_read() except that it uses
  kvaddr_t instead of unsigned long for the kernel virtual address.
- Add a new kvm_arch switch of routines needed by a vmcore backend.
  Each backend is responsible for implementing kvm_read2() for a given
  vmcore format.
- Use libelf to read headers from ELF kernels and cores (except for
  powerpc cores).
- Add internal helper routines for the common page offset hash table used
  by the minidump backends.
- Port all of the existing kvm backends to implement a kvm_arch switch and
  to be cross-friendly by using private constants instead of ones that
  vary by platform (e.g. PAGE_SIZE).  Static assertions are present when
  a given backend is compiled natively to ensure the private constants
  match the real ones.
- Enable all of the existing vmcore backends on all platforms.  This means
  that libkvm on any platform should be able to perform KVA translation
  and read data from a vmcore of any platform.

43518607b2 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.
