8369ba427a libbe(3)/bectl(8): Make consistent with beadm
vermaden (maintainer of beadm) points out the following inconsistencies:
- "missing command" is not printed prior to usage if the error is simply a
   missing command; this should be obvious from the context
- "bectl rename" isn't using the "don't unmount" flag (zfs rename -u), so
   the active BE can't be renamed. It doesn't make sense in our context to
   *not* use -u, so use it.

Documentation updates reflect the above and note an inconsistency with the
'destroy' command that is consistent with other parts of the base system.

A fix for libbe(3) not properly being installed to /lib is included.
SHLIBDIR should have been added when it was moved in r337995.

ff7b3f731a Extend tbrsize heuristic in pfctl(8) to provide a sensible value for
higher bandwidth interfaces.  The new value is used above 2.5 Gbps,
which is the highest standard rate that could be used prior to
r338209, so the default behavior for all existing systems should
remain the same.

The value of 128 chosen is a balance between being big enough to
reduce potential precision/quantization effects stemming from frequent
bucket refills over small time intervals and being small enough to
prevent a greedy driver from burst dequeuing more packets than it has
available hardware ring slots for whenever altq transitions from idle
to backlogged.

ce1ba01c8a When trying to match the nomatch event passed to us, attempt to look
up the device described by the nomatch event in the device tree. If we
find it, then if the device is marked as have already attached to a
device once, then ignore the device.

This keeps us from reloading the device driver when it has just been
manually unloaded. All devies that have had a driver attach to them at
least once no longer participate in pnp-based autoloading.

d36967bd2b Add a new device flag: DF_ATTACHED_ONCE
This flag is set once the device has been successfully attached. When
set, it inhibits devmatch from trying to match the device. This in
turn allows kldunload to work as expected. Prior to the change, the
driver would immediately reload because devmatch had no notion that
the driver had once been attached, and therefore shouldn't participate
in further matching.

db9db0e790 bectl(8): jail: Tear down jail by default after command exits
Add a -U flag to get back the old behavior. The new behavior is a little
more friendly to the common use cases, jail the BE and execute a script.
Having the jail torn down automatically when the script is finished, or when
you exit the shell, is a little more friendly than having to remember to
`bectl ujail`.

Batch mode (-b) will continue to leave the jail up, as it's assumed the
caller has other intentions.

249cc75fd1 Extended pf(4) ioctl interface and pfctl(8) to allow bandwidths of
2^32 bps or greater to be used.  Prior to this, bandwidth parameters
would simply wrap at the 2^32 boundary.  The computations in the HFSC
scheduler and token bucket regulator have been modified to operate
correctly up to at least 100 Gbps.  No other algorithms have been
examined or modified for correct operation above 2^32 bps (some may
have existing computation resolution or overflow issues at rates below
that threshold).  pfctl(8) will now limit non-HFSC bandwidth
parameters to 2^32 - 1 before passing them to the kernel.

The extensions to the pf(4) ioctl interface have been made in a
backwards-compatible way by versioning affected data structures,
supporting all versions in the kernel, and implementing macros that
will cause existing code that consumes that interface to use version 0
without source modifications.  If version 0 consumers of the interface
are used against a new kernel that has had bandwidth parameters of
2^32 or greater configured by updated tools, such bandwidth parameters
will be reported as 2^32 - 1 bps by those old consumers.

All in-tree consumers of the pf(4) interface have been updated.  To
update out-of-tree consumers to the latest version of the interface,
define PFIOC_USE_LATEST ahead of any includes and use the code of
pfctl(8) as a guide for the ioctls of interest.

9544e6dcf1 Make NVMe compatible with the original API
The original NVMe API used bit-fields to represent fields in data
structures defined by the specification (e.g. the op-code in the command
data structure). The implementation targeted x86_64 processors and
defined the bit fields for little endian dwords (i.e. 32 bits).

This approach does not work as-is for big endian architectures and was
changed to use a combination of bit shifts and masks to support PowerPC.
Unfortunately, this changed the NVMe API and forces #ifdef's based on
the OS revision level in user space code.

This change reverts to something that looks like the original API, but
it uses bytes instead of bit-fields inside the packed command structure.
As a bonus, this works as-is for both big and little endian CPU
architectures.

While it could be preferred to do this at insert in libbe(3), there's no

another to print everything else.

6040822c4e Make timespecadd(3) and friends public
The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.

Our kernel currently defines two-argument versions of timespecadd and
timespecsub.  NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions.  Solaris also defines a three-argument version, but
only in its kernel.  This revision changes our definition to match the
common three-argument version.

Bump _FreeBSD_version due to the breaking KPI change.

"record-state" is similar to "keep-state", but it doesn't produce implicit
O_PROBE_STATE opcode in a rule. "set-limit" is like "limit", but it has the
same feature as "record-state", it is single opcode without implicit
O_PROBE_STATE opcode. "defer-action" is targeted to be used with dynamic
states. When rule with this opcode is matched, the rule's action will
not be executed, instead dynamic state will be created. And when this
state will be matched by "check-state", then rule action will be executed.
This allows create a more complicated rulesets.

af74661403 ifconfig(8): Attempt to render non-printable sequences w/ UTF-8 Environment
Currently ifconfig(8) only prints the hex representation of ssid names
with non-ASCII characters. Many modern terminals are able to properly render
non-ASCII characters. This change checks if the terminal charmap is UTF-8,
and if so, will render the characters, rather than the hex value.

This behavior is circumvented by running ifconfig(8) in a non-UTF8 locale;
e.g. C or POSIX.

It was pointed out by kp@ during the review that APs have the option to
broadcast whether their SSIDs may be interpreted as UTF-8. Ideally, we would
honor this and only attempt this behavior if it's so-broadcasted by the AP.

However, a sample survey showed that hostapd will advertise this if
indicated in config but it doesn't seem to be so common in the AP market, so
this would be effectively useless as we'll rarely know if the SSID should be
renderable as UTF-8.

Despite this, it was decided to be OK with this anyways- there's a
straightforward path to doing it the right way based on advertisement by AP
if we need to go that route, and one can revert to old behavior easily
enough at runtime if we get it wrong.

Rather then combining hardlink creation for the geom(8) binary with
shared library build, move libraries to src/lib/geom so they are
built and installed normally.  Create a common Makefile.classes
which is included by both lib/geom/Makefile and sbin/geom/Makefile
so the symlink and libraries stay in sync.

The relocation of libraries allows libraries to be build for 32-bit
compat.  This also reduces the number of non-standard builds in
the system.

This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit

unless GEOM_LIBRARY_PATH is set appropriatly in the environment.

"return-icmp". Yet there is a 3rd category of traffic passing through pf:
Packets matching a "pass" rule but when applying the rule fails. This happens
when redirection table is empty or when src node or state creation fails. Such
rules always fail silently without notifying the sender.

ce16585796 This application (veriexecctl) handles reading a fingerprints file
containing paths, fingerprints, and optional option flags which in turn
get pushed into the MAC/veriexec meta-data store via the veriexec device.

The format of the fingerprints file is as follows:
path type fingerprint options

The type of fingerprint supported depends on what MAC/veriexec fingerprint
modules have been loaded into the system. The veriexecctl application is
able to determine which ones are available by consulting the
security.mac.veriexec.algorithms sysctl.

The following options are currently supported in MAC/veriexec and by the
veriexecctl application:

indirect
  If this option is set then the executable cannot be invoked directly, it
  can only be used as an interpreter in shell scripts.
file
  Indicates that the fingerprint is associated with a file, not an
  executable. Files have their fingerprints verified during open(2) and are
  automatically made read only. This option may be used to verify shared
  libraries have not been tampered with.
no_ptrace
  If this option is set then the executable cannot be traced with the
  ptrace(2) process tracing and debugging call.
trusted
  If this option is set then the executable is allowed to write to the

Implement MK_NVME now that the expression for where NVMe is
complicated. Default it to "yes" for x86 and powerpc64 and
no everywhere else. Use it in camcontrol to define WITH_NVME
for those platforms where we support nvme.

This should fix the newly introduced nvme files to camcontrol

- Preserve non-EEXISTS errors for exit status from SIOCSLAGGPORT,
