f4b38c360e rc.d: unbreak sysctl lastload
/etc/rc.d/securelevel is supposed to run /etc/rc.d/sysctl lastload
late at boot time to apply /etc/sysctl.conf settings that fail
to apply early. However, this does not work in default configuration
because of kern_securelevel_enable="NO" by default.

Add new script /etc/rc.d/sysctl lastload that starts unconditionally.

f5b5de1a32 ipfw: reload sysctl.conf variables if needed
Currently ipfw has multiple components that are not parts
of GENERIC kernel like dummynet etc. They can bring in important
sysctls if enabled with rc.conf(5) and loaded with ipfw startup script
by means of "required_modules" after initial consult
with /etc/sysctl.conf at boot time. Here is an example of one
increasing limit for dummynet hold queues that defaults to 100:

net.inet.ip.dummynet.pipe_slot_limit=1000

This makes it possible to use ipfw/dummynet rules such as:

ipfw pipe 1 config bw 50Mbit/s queue 1000

Such rule is rejected unless above sysctl is applied.
Another example is a group of net.inet.ip.alias.* sysctls
created after libalias.ko loaded as dependency of ipfw_nat.

This is not a problem if corresponding code compiled in custom kernel
so sysctls exist when sysctl.conf is read early or kernel modules
loaded with a loader. This change makes it work also for GENERIC
and modules loaded by means of rc.conf(5) settings.

This also moves the 'linux' rc script slightly earlier, which

f30f11f878 wait for device mounts in zpool and dumpon
If the root file system is composed from multiple devices, wait for
devices to be ready before running zpool and dumpon rc scripts.

An example of this is if the bulk of the root file system exists on a
fast device (e.g. NVMe) but the /var directory comes from a ZFS dataset
on a slower device (e.g. SATA). In this case, it is possible that the
zpool import may run before the slower device has finished being probed,
leaving the system in an intermediate state.

Fix is to add root_hold_wait to the zpool and dumpon (which has a
similar issue) rc scripts.

09673fc0f3 mountd(8): generate a syslog message when the "V4:" line is missing
Daniel reported that NFSv4 mounts were not working despite having
set "nfsv4_server_enable=YES" in /etc/rc.conf.  Mountd was logging a
message that there was no /etc/exports file.
He noted that creating a /etc/exports file with a "V4:" line in it
was needed make NFSv4 mounts work.
At least one "V4:" line in one of the exports(5) file(s) is needed to
make NFSv4 mounts work. This patch fixes mountd.c so that it logs a
message indicting that there is no "V4:" line in any exports(5)
file when NFSv4 mounts are enabled.
To avoid this message being generated erroneously, /etc/rc.d/mountd
is updated to make sure vfs.nfsd.server_max_nfsvers is properly set
before mountd(8) is started.

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.

24f44a445c Remove dependency on files in /usr/bin
In order to reduce the pre-requisites of this file, implement the
pattern matching and creation of a temporary test directory without
use of grep respectively mktemp.

The new version makes it possible to provide a writable /tmp in any
case and independently of other local or remote file systems (except /
and /dev) being mounted.

The use of "dd if=/dev/random" has the same dependency on /dev/random
being operational as the previous version that used "mktemp". If this
is found to be an issue on platforms that do not have gathered
sufficient entropy at the time when this scriot is run, I suggest to
replace the "dd" command with "ps lauxww" to get a somewhat random

e5912dcf20 Revert r367291 (KEYWORD: shutdown for rc.d/zfs)
The problem is that zfs is asked to stop too early in the shutdown
sequence. Other services, such as syslog may still be running and have some
files open (e.g., under /var/log). This of course causes the messages like:

  cannot unmount '/var/run': umount failed
  cannot unmount '/var/log': umount failed
  cannot unmount '/var': umount failed
  cannot unmount '/usr/home': umount failed
  cannot unmount '/usr': umount failed
  cannot unmount '/': umount failed

For now, let's remove the shutdown KEYWORD from the zfs service, as people are
reporting problems in their setups:
https://lists.freebsd.org/pipermail/freebsd-current/2020-November/077559.html

In the future, we may think of stopping zfs on shutdown after all the other
services and just before init(8) exits. Another interesting option might be to
a new rcorder(8) KEYWORD like "shutdownjail", but this idea would need to be
discussed a bit.

meowthink@gmail.com reported that the gssd daemon was not
starting, because /etc/rc.d/gssd was executed before his local
/usr file system was mounted.
He fixed the problem by adding mountcritlocal to the REQUIRED
line.

This fix seems safe and works for a separately mounted /usr file
system on a local disk.
The case of a separately mounted remote /usr file system (such as
NFS) is still broken, but there is no obvious solution for that.
Adding mountcritremote would fix the problem, but it would
cause a POLA violation, because all kerberized NFS mounts
in /etc/fstab would need the "late" option specified to work.

When that is set, make vfs.nfsd.server_min_vers=4 and set "=R"

Setting vfs.nfsd.server_min_vers=4 tells nfsd to not register with rpcbind.

0cadbd6cd2 rc.d/zfs: Add shutdown to KEYWORDS
The problem is that Without walling /etc/rc.d/zfs on shutdown, resources
associated with ZFS mounts are not freed and the jails will remain in dying
state. In addition, the dataset is now in a dangling state, as the jail it
is attached to is dying.

A known workaround for jails was to add the following lines
to /etc/jail.conf, to make sure that "service zfs stop" is run
when the jail is stopped:

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

While the workaround seems to be okay-ish for the jail situation, it is
still unclean. However, for physical hosts this may wreak havoc with the
pool if shared spares are used, as "zfs unshare" is never invoked on
shutdown.

bd0e0447cb Destroy cloned interfaces at netif stop, netif restart and shutdown.
This is especially important during shutdown because a child interface
of lagg with WOL enabled will not enable WOL at interface shutdown and
thus no WOL to wake up the device (and machine).

9ef9175912 [pf] /etc/rc.d/pf should REQUIRE routing
When a system with pf_enable="YES" in /etc/rc.conf uses hostnames in
/etc/pf.conf, these hostnames cannot be resolved via external nameservers
because the default route is not yet set. This results in an empty
(all open) ruleset.

Since r195026 already put netif back to REQUIRE, this change does not affect
the issue that the firewall should rather have been setup before any
network traffic can occur.

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.
