77e1ccbee3 introduced a bug whereby
rc scripts in etc/rc.d and $local_startup failed to parse output

77e1ccbee3 introduced parallel execution
of rc. It separated groups with line feeds (\n) and elements within
groups using spaces. This is a natural separation due to rcorder
using spaces and lines to separate elements within groups with groups
of services separated by line feeds.
77e1ccbee3 parses the output from rcorder
by setting $IFS. However it failed to reset $IFS to default ' \t\n'
prior to calling find_local_scripts_new(), causing find_local_scripts_new()
to fail parsing $local_startup for site-specific local rc scripts, i.e.
${LOCALBASE}/etc/rc.d. This caused daemons from ports and packages such
as postfix, dovecot, nut, and others in ${LOCALBASE} not to be started.

A known workaround for jails was to add the following lines

exec.stop = "/bin/sh /etc/rc.shutdown";
exec.stop += "/usr/sbin/service zfs stop || /usr/bin/true";

This change allows to specify a watchdog(9) timeout for a system
shutdown. The timeout is activated when the watchdogd daemon is
stopped. The idea is to a prevent any indefinite hang during late
stages of the shutdown. The feature is implemented in rc.d/watchdogd,
it builds upon watchdogd -x option.
Note that the shutdown timeout is not actiavted when the watchdogd
service is individually stopped by an operator. It is also not
activated for the 'shutdown' to the single-user mode. In those cases it
is assumed that the operator knows what they are doing and they have
means to recover the system should it hang.
Significant subchanges and implementation details:
- the argument to rc.shutdown, completely unused before, is assigned to
rc_shutdown variable that can be inspected by rc scripts
- init(8) passes "single" or "reboot" as the argument, this is not
changed
- the argument is not mandatory and if it is not set then rc_shutdown is
set to "unspecified"
- however, the default jail management scripts and jail configuration
examples have been updated to pass "jail" to rc.shutdown, just in case
- the new timeout can be set via watchdogd_shutdown_timeout rc option
- for consistency, the regular timeout can now be set via
watchdogd_timeout rc option
- watchdogd_shutdown_timeout and watchdogd_timeout override timeout
specifications in watchdogd_flags
- existing configurations, where the new rc options are not set, should
keep working as before
I am not particularly wed to any of the implementation specifics.
I am open to changing or removing any of them as long as the provided
functionality is the same (or very close) to the proposed one.
For example, I think it can be implemented without using watchdogd -x,
by means of watchdog(1) alone. In that case there would be a small
window between stopping watchdogd and running watchdog, but I think that
that is acceptable.

In 2013 the security chapter of the Handbook was updated in r42501 to
suggest limiting access to the system accounting file [*1] by creating the
initial file with a mode of 0600. This was in part based on a discussion in
the forums [*2]. Unfortunately, this advice is overridden by the fact that a
new file is created as part of periodic daily processing, and the file mode
is set by the rc.d/accounting script.
These changes update the accounting script to create the directory with mode
0750 if it doesn't already exist, and to create the daily file with mode
0640. This limits write access to root only, read access to root and members
of wheel, and eliminates world access completely. For admins who want to
prevent even members of wheel from accessing the files, the mode of the
/var/account directory can be manually changed to 0700, because the script
never creates or changes that directory if it already exists.
The accounting_rotate_log() function now also handles the error cases of no
existing log file to rotate, and attempting to rotate the file multiple
times (.0 file already exists).
Another small change here eliminates the complexity of the mktemp/chmod/mv
sequence for creating a new acct file by using install(1) with the flags
needed to directly create the file with the desired ownership and
modes. That allows coalescing two separate if checkyesno accounting_enable

backed up by dump(8) or other automated backup software that honors the file
flag.
Do not produce an error if the target file resides on a filesystem that does
not support file flags (e.g., msdos /boot).

ifconfig(8) syntax allows to specify only single address_family,
so we need additional invocation of ifconfig to support configuration
of cloned gif interface that may use different address families
for its internal and external addresses.
Also, ifconfig(8) does not allow to omit "inet6" keyword for address family
specifying IPv6 addresses as outer addresses of the interface.
Also, address_family is not "parameter" and it has to go before parameters
including "tunnel" keyword, so "ifconfig gif0 tunnel inet6 $oip1 $oip2" would be
wrong syntax and only "ifconfig gif0 inet6 tunnel $oip1 $oip2" is right.
With this change, the following works:
gifconfig_gif0="inet6 2a00::1 2a01::1"
ifconfig_gif0="inet 10.0.0.1 10.0.0.2 netmask 255.255.255.252"

The goal of saving entropy in Fortuna is two-fold: (1) to provide early
availability of the random device (unblocking) on next boot; and (2), to
have known, high-quality entropy available for that initial seed. We know
it is high quality because it's output taken from Fortuna.
The FS&K paper makes it clear that Fortuna unblocks when enough bits have
been input that the output //may// be safely seeded. But they emphasize
that the quality of various entropy sources is unknown, and a saved entropy
file is essential for both availability and ensuring initial
unpredictability.
In FreeBSD we persist entropy using two mechanisms:
1. The /etc/rc.d/random shutdown() function, which is used for ordinary
shutdowns and reboots; and,
2. A cron job that runs every dozen minutes or so to persist new entropy, in
case the system suffers from power loss or a crash (bypassing the
ordinary shutdown path).
Filesystems are free to cache dirty data indefinitely, with arbitrary flush
policy. Fsync must be used to ensure the data is persisted, especially for
the cron job save-entropy, whose entire goal is power loss and crash safe
entropy persistence.
Ordinary shutdown may not need the fsync because unmount should flush out
the dirty entropy file shortly afterwards. But it is always possible power
loss or crash occurs during the short window after rc.d/random shutdown runs
and before the filesystem is unmounted, so the additional fsync there seems
harmless.

It seems my subconcious plan in r345088 to not only prefer IPv6 autoconf
but to also slowly deteriorate legacy IP auto-configuration was uncovered
way too early.
In case IPv6 is a thing yet ipv6_autoconfif was not true, we would not
bring up the interface yet tell the follow-up DHCPv4 configuration in
ifconfig_up() that we did. So unless you were doing SYNCDHCP or IPv6
you would not get legacy-IP DHCPv4 configuration.
I see multiple problems here: (a) people not yet using IPv6 (obviously a
problem), and (b) the dhclient startup script not running dhclient in
that case despite configured to do so (needs to be investigated seperately).

Before this change we would only run rtsol on an interface which was
set to accept_rtadv and did not have rtsold enabled. This change
removes the latter condition and always runs rtsol (rather than the
deferred rtsold) to reduce the delay until we send the first RS.
This change will also handle the accept_rtadv before dhcp hence
starting IPv6 auto-configuration before IPV4 DHCP.
This change is intended for FreeBSD 13 and later only and will not be MFCed.

When piping to awk, it's almost always an anti-pattern to use 'grep'
first.
When not in a pipeline, sometimes it is faster to use tail, as awk
must process all the lines in the input stream, and won't 'seek'.
In a pipeline, both grep and awk must process all lines, so we might
as well skip the extra process creation for tail and just use awk
for all the processing.

Some rc scripts in ports (e.g. uwsgi, apache, openvpn) allow for
'application profiles' that usually require the rc script to be invoked
again for each active profile. Because there's no consistent way to
determine the path because it differs between manual/service(8) invocations
and /etc/rc invocations, this leads to patterns like these:
- www/uwsgi hardcodes the script path
- security/openvpn guesses either $_file or $0 based on $0 = /etc/rc
Instead of forcing rc scripts to guess, provide an rc_service variable to
the scripts that gets set appropriately both for direct execution or when a
script is being executed via run_rc_script (e.g. /etc/rc).
This is our analog of an OpenRC variable with the same name, different case
(RC_SERVICE).

Currently, rc.inidiskless assumes that local system configuration
changes are kept in some mountable file system. For example,
nanobsd uses dedicated partition mounted as /cfg for this.
However, small embedded devices like MIPS routers may have no enough flash
space to keep full-blown file system but have only one or couple
small flash blocks to keep persistent local configuration overrides.
This change extends rc.initdiskless and introduces ability to run auxiliary
command /conf/T/M/extract that is supposed to extract configuration overrides
from such local storage.
For example, the command /conf/default/etc/extract may contain something like:
cd "$1" && bsdcpio --quiet -idu < /dev/map/cfg
bsdcpio command extracts compressed archive from the storage to /etc
assuming the storage is exposed by the kernel as /dev/map/cfg to userland.

testing pkgbase at the moment there is no (automatic) way to pick

As a result rather than also moving init(8) to its own package,
back out the part of the change in r339413 that moved rc* to its
own package and defer creating new packages until the
infrastructure is in place to handle these cases.
Both init and rc* are considered too problematic to be lost by

(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.
