Make a note in the newfs.8 manual page to update the first backup
superblock location when changing the default fragment size for
the filesystem.
Reported by: O. Hartmann
It allows to read and write block descriptors alike to mode page parameters.
It allows to change block size or short-stroke HDDs or overprovision SSDs.
Depenting on -P parameter the change can be either persistent or till reset.
In case of block size change device may need reformat after the setting.
In case of SSD overprovisioning format or sanitize may be needed to really
free the flash.
During implementation appeared that csio_encode_visit() can not handle
integers of more then 4 bytes, that makes 8-byte LBA handling awkward.
I had to split it into two 4-byte halves now.

This commit imports the new fusefs driver. It raises the protocol level
from 7.8 to 7.23, fixes many bugs, adds a test suite for the driver, and
adds many new features. New features include:
* Optional kernel-side permissions checks (-o default_permissions)
* Implement VOP_MKNOD, VOP_BMAP, and VOP_ADVLOCK
* Allow interrupting FUSE operations
* Support named pipes and unix-domain sockets in fusefs file systems
* Forward UTIME_NOW during utimensat(2) to the daemon
* kqueue support for /dev/fuse
* Allow updating mounts with "mount -u"
* Allow exporting fusefs file systems over NFS
* Server-initiated invalidation of the name cache or data cache
* Respect RLIMIT_FSIZE
* Try to support servers as old as protocol 7.4
Performance enhancements include:
* Implement FUSE's FOPEN_KEEP_CACHE and FUSE_ASYNC_READ flags
* Cache file attributes
* Cache lookup entries, both positive and negative
* Server-selectable cache modes: writethrough, writeback, or uncached
* Write clustering
* Readahead
* Use counter(9) for statistical reporting

I merged passthru.c from the wrong branch (it was a branch that went further in
a direction I wound up not taking). Fix the mismerge and turn passthru on.
NVMe reservations are quite alike to SCSI persistent reservations and
can be used in clustered setups with shared multiport storage.

r348215 changed jail_getid(3) to validate passed-in jids as active jails
(as the function is documented to return -1 if the jail does not exist).
This broke the jail option (in some cases?) as the jail historically hasn't
needed to exist at the time of rule parsing; jids will get stored and later
applied.
Fix this caller to attempt to parse *av as a number first and just use it
as-is to match historical behavior. jail_getid(3) must still be used in
order for name arguments to work, but it's strictly a fallback in case we
weren't given a number.

It allows to delete all user data from NVM subsystem in one of 3 methods.
It is a close equivalent of SCSI SANITIZE command of `camcontrol sanitize`,
so I tried to keep arguments as close as possible.
While there, fix supported sanitize methods reporting in `identify`.

Add few new arguments to `nvmecontrol log` subcommand.
MFC after: 2 weeks

While very useful by itself, it also makes `nvmecontrol` not depend on
hardcoded device names parsing, that in its turn makes simple to take
nvdX (and potentially any other) device names as arguments.
Also added IOCTL bypass from nvdX to respective nvmeYnsZ makes them
interchangeable for management purposes.

This adds several previously missed but important subcommands to list
namespaces and controllers. It also fixes few previously added but
just found with real testing to be broken subcommands.
Also while there, add possibility to explicitly specify nsid for
`nvmecontrol identify` subcommand. It may be useful to specify nsids
not having own devices, for example 0xffffffff, or just newly created
ones.

While old devices may not support 10 byte MODE SENSE/MODE SELECT commands,
new ones may not be able to report all mode pages with 6 byte commands.
This patch makes camcontrol by default start with 10 byte commands and
fall back to 6 byte on ILLEGAL REQUEST error, or 6 byte can be forced.

FUSE file systems can optionally support interrupting outstanding
operations. However, the file system does not identify to the kernel at
mount time whether it's capable of doing that. Instead it signals its
noncapability by returning ENOSYS to the first FUSE_INTERRUPT operation it
receives. That's a problem for reliable signal delivery, because the kernel
must choose which thread should get a signal before it knows whether the
FUSE server can handle interrupts. The problem is even worse because the
FUSE protocol allows a file system to simply ignore all FUSE_INTERRUPT
operations.
Fix the signal delivery logic by making interruptibility an opt-in mount
option. This will require a corresponding change to libfuse, but not to
most file systems that link to libfuse.
Bump __FreeBSD_version due to the new mount option.

These are mostly compatible with Linux, with three exceptions.
1. We don't do metadata segment stuff. Our passthrough interface
doesn't cope. The code is there, but generates an error.
2. Linux lets you specify a namespace ID for the command. We current
do not: we get ours from the namespace device, or pass in a generic
one. Generally, this will lead to the same command, but FreeBSD's
is safer since you can't specify the wrong id.
3. --show-command outputs to stderr instead of stdout so you can both
see your command, and capture its output with a simple redirect.

Create a set of routines and structures to hold the data for the args
for a command. Use them to generate help and to parse args. Convert
all the current commands over to the new format. "comnd" is a hat-tip
to the TOPS-20 %COMND JSYS that (very) loosely inspired much of the
subsequent command line notions in the industry, but this is far
simpler (the %COMND man page is longer than this code) and not in the
kernel... Also, it implements today's de-facto
command [verb]+ [opts]* [args]*
format rather than the old, archaic TOPS-20 command format :)
This is a snapshot of a work in progress to get the nvme passthru
stuff committed. In time it will become a private library and used
by some other programs in the tree that conform to the above pattern.

gcc hates dt < CC_DT_NONE since it can never be true when dt is an unsigned
type. Since that's a compiler choice and may be affected by weird stuff, instead
use (unsigned)dt > CC_DT_UNKNOWN to test for bounds error since that will work
regardless of the signedness of dt.

We remove IPSEC only in parts of the tree, and not others. RELEASE_CRUNCH to
disable it has not kept up with all its uses. Remove it. Should there be a real
need to disable IPSEC, one that hasn't shown up in the base system to date,
it can be re-added behind a WITHOUT_IPSEC build option.
