Hello List Subscirbers,
in the past the module was loaded automatically upon NTPD server
startu
p.
It's no longer true, now it has to be loaded earlier.
Perhaps people running stable/14 might find this message useful.
Hmm, works for me on main and stable/14.
So... I noticed this for (precisely) one of the five machines I have
that track stable/14 -- the other 4 get mac_ntpd loaded
automagically as
usual.
In the failing case, it seems that
sysctl security.mac.version
yielded
sysctl: unknown oid 'security.mac.version'
I only get this if I build a kernel without "options MAC". But in this
no mac_* kernel modules are built and ntpd fails with:
Starting ntpd.
daemon control: got EOF
/etc/rc.d/ntpd: WARNING: failed to start ntpd
In this case, you'll find something like
Need MAC 'ntpd' policy enabled to drop root privileges
daemon child exited with code 255
in ntpd logfile (/var/db/ntpd.log in my case, but
possibly /var/log/messages by default).
I don't understand why some systems (those in this thread) have a
problem
not loading mac_ntpd while others, i.e. my stable/14 at $JOB, are
fine. I'd
like to try to understand the differences between those that work and
those
that don't.
First of all, the ntpd rc script bails without saying why when it
encounters a problem. can_run_nonroot() simply returns a bad return code
leaving us to wonder why.
The first order of business is to produce a patch to indicate why it
bails. Please apply the attached patch and let me know where it fails.
Messages will be printed to stderr and to /var/log/messages (assuming
daemon.err is sent there).

To reproduce: use config matching the regex from the above, for example
add line:
logfile /var/log/ntp.log
to the ntp.conf
15-CURRENT is also affected this way. That's a bit odd that nobody
reported it yet.
Problems made by can_run_nonroot function can be fixed by removing lines
60-64 from the starting script.

What is in your ntpd_config in rc.conf?
# grep ntpd_config /etc/rc.conf /etc/defaults/rc.conf
/etc/defaults/rc.conf:ntpd_config="/etc/ntp.conf" # ntpd(8)
