Add some sanity checks when service jails are used in jails:
- children.max > 0
- children.max - children.cur > 0
The nesting is too deep at those places to have a sane formatting, so no
line wrapping at the usual column.
If someone has a better idea how to format this: feel free to go ahead.
Clarify that the "sysvipc" svcj option inherits from the host / parent.
Add "sysvipcnew" which creates a new SysV namespace for the service
jail.
Sanity check that only one of them is used.
New variable ${name}_offcmd may be used to supply commands
executed if named service is not enabled. Previously start_precmd
could be used for such a task but now rc.subr(8) does not call it
if a service is not enabled.

At the moment, if bootrace profiling is enabled, autoboot is not
exported to the rc scripts. This causes fsck to not check the root
filesystem. To fix this, pass _boot, rc_fast and autoboot to the

Reload is used for service reconfiguration as well
and lacks a NAME_prepend-like mechanism so it makes
sense to extend the NAME_reload hook into this
action.
precmd may use configuration checks and blocks setup
from doing its designated work (e.g. nginx). In moving
the invoke of the setup script in front allows us to
provide custom scripts for config file generation and
fixing prior to precmd checking configuration integrity.
Also introduce _run_rc_setup to separate the launcher
from the main one. Let it run correctly in the case
of restart_precmd and block further execution as
would be the case in start due to the internal plumbing
of restart being split into calling stop and start
afterwards.

This gives more permissions to services (e.g. network access to
services which require this) when they are started as an automatic
service jail.
The sshd patch is important for the sshd-related functionality as
described in the man-page in the service jails part.
The location of the added env vars is supposed to allow overriding them
in rc.conf, and to hard-disable the use of svcj for some parts where it
doesn't make sense or will not work.
Only a subset of all of the services are fully tested (I'm running this
since more than a year with various services started as service jails).
The untested parts should be most of the time ok, in some edge-cases
more permissions are needed inside the service jail.

This takes a rc.d-service and starts it in a jail which shares the same
root-path as the host (or parent jail) and may inherit the network from
the host (or parent jail). Per service there is the possibility to
specify some arguments which give more permissions (e.g. netv4, netv6,
sysvipc...).

Introduce hw.bus.devctl_nomatch_enabled and use it to suppress NOMATCH
until devmatch runs
There's a lot of NOMATCH events generated at boot. We also run devmatch
once during early boot to load unmatched devices. To avoid redundant
work, don't start generating NOMATCH events until after devmatch runs.
Set hw.bus.devctl_nomatch_enabled=1 just before we run devmatch. The
kernel will suppress NOMATCH events until this is set to true.
This saves about 170ms from the boot on aarch64 running atop Apple

This setting causes the NFS server to check that all RPCs are sent from
a privileged (<= 1023) port, rejecting those that are not. This
slightly raises the bar for a user with network access to an
unauthenticated NFS server to access exported NFS filesystems.
Users that use traditional NFS clients (e.g., those provided by FreeBSD
or Linux) should not see any difference, assuming that unprivileged
filesystem mounting is disallowed.
Note that the setting is per-VNET, so may be overridden in VNET jails
without affecting the rest of the system.

basename, sed and tty are all in /usr/bin and not available
until /usr is mounted.
basename and tty we can replace with a function, but sed is more
important. Fix o_verify to just use shell builtins, and
rc_trace should avoid trying to set RC_LEVEL until sed is available.
Debugging boot issues can be helped by
logging each rc.d script as it is run
and being able to selectively enable/disable set -x
debug.sh provides an elaborate framework for debugging shell scripts.
For secure systems, we want to be paranoid about what we read
during boot.
dot() simply reads (.) arg file if it exists
vdot() if mac_veriexec is active, ignore unverified files
otherwise behaves much the same as dot()
safe_dot() in safe_eval.sh allows reading an untrusted file;
limiting the input to simple variable assignments.
In load_rc_config allow caller to provide an option to indicate how to
handle its arg:
-v use vdot()
-s use sdot() which will try to use vdot() and fallback to safe_dot()
The default is to read using dot()
rc_run_scripts()
encapsulate the running of rc.d scripts
so that we can easily call it more than twice.
We vdot local.rc.subr to pick up extensions (like
run_rc_scripts_final) and overrides.
We also allow rc.subr.local or rc.conf to set rc_config_xtra
eg (rc_config_xtra=XXX for historic compatibility)
rc use set -o verify around the reading in of rc.subr
This has no effect if mac_veriexec is not active, but if it is; ensures
rc.subr has not been tampered with.

Since 13.1, /etc/rc.d/jail has looked for a per-jail config file in
/etc/jail.conf.d. For RELENG 14, the ".include" directive was added to
jail(8), with a sample line in the jail.conf(5) man page that includes
"/etc/jail.conf.d/*.conf".
These two use cases don't work together. When the jail.conf.d files
are included from a master jail.conf, the files in jail.conf.d are
likely to hold only partial configurations, and shouldn't be directly
loaded by rc.d/jail. But there are existing configurations that depend
on the current rc.d behavior. While users could be advised not to
include from /etc/jail.conf.d, it's the natural choice even if not
mentioned in jail.conf.5.
The workaround is for rc.d/jail to continue to load the individual
files, but only when /etc/jail.conf doesn't include from that
directory (via a simple grep test), This allows the current use
while not breaking the previous use.

For a service that sets an rcvar, there is a check whether it has been
enabled before the actual command is executed. If the check fails, one
gets a message to enable it and the returned exit status is 0.
However, this is usually undesirable for the status command, which is
a) supposed to check whether the service is running anyway and
b) returns a non-zero exit code if that is not the case.
Thus, skip the check for the status command.
