rc.subr(8): MFC: introduce ${name}_offcmd

2024-06-17T05:06:59+00:00

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.

Fix devd startup script to use it instead of start_precmd.

kdc: Add restart option

2024-04-29T12:51:11+00:00

Add a new kdc_restart rc variable that manages kdc (or krb5kdc) under
daemon(8). This automatically restarts the kdc should it fail, i.e.
when it's configured to use LDAP as a backend and cannot connect to its
LDAP directory.

Set kdc_restart="YES" to auto restart kdc on abnormal termination.

Set kdc_restart_delay="N" to the number of seconds to delay before
restarting the kdc. The daemon(8) default seconds applies when not set.

rc.d/kdc: Support start of MIT krb5kdc

2024-01-29T00:26:13+00:00

Some users wishing to use the MIT krb5kdc have discovered the
kdc script workaround applied to the MIT krb5 ports is insufficient.
Let's build into this rc script the smarts to determine whether
base or ports Hiemdal kdc is being invoked or the MIT krb5kdc.

While at it, remove kdc_start_precmd(). This will simplify a future
jail patch.

rc.d/routing: Correct setting default gateway for each FIB

2023-08-30T12:06:51+00:00

There was a mistake in the previous commit, it used the incorrect
spelling of the FIB variable name and was not functional

Also corrects an issue with the IPv6 default route variable name.

rc/WPA: driver_bsd.c: backout upstream IFF_ change and add logging

2023-06-26T09:00:55+00:00

This reverts the state to our old supplicant logic setting or clearing
IFF_UP if needed.  In addition this adds logging for the cases in which
we do (not) change the interface state.

Depending on testing this seems to help bringing WiFi up or not log
any needed changes (which would be the expected wpa_supplicant logic
now).  People should look out for ``(changed)`` log entries (at least
if debugging the issue; this way we will at least have data points).

There is a hypothesis still pondered that the entire IFF_UP toggling
only exploits a race in net80211 (see further discssussions for more
debugging and alternative solutions see D38508 and D38753).
That may also explain why the changes to the rc startup script [1]
only helped partially for some people to no longer see the
continuous CTRL-EVENT-SCAN-FAILED.

It is highly likely that we will want further changes and until
we know for sure that people are seeing ''(changed)'' events
this should stay local.  Should we need to upstream this we'll
likely need #ifdef __FreeBSD__ around this code.

Remove ifconfig down/up workaround (bfb202c4554a) in
rc.d/wpa_supplicant as it is no longer needed.

motd: MFC: unbreak for source upgrade

2023-06-26T04:26:47+00:00

In case of source upgrade path from 12.x proper merge of new /etc
installs /etc/motd.template. Becase of that, the system is left
without symlink /etc/motd -> /var/run/motd but with stale /etc/motd contents.

Fix it creating symlink despite of presence of /etc/motd.template.
