Public bug reported:
The fix for bug #2032805 allows chronyd to use one PTP clock/interface
with timemaster, but not more than one.
Steps to reproduce (config must contain valid network interface names):
$ cat > minimal_timemaster.conf
# List two separate interfaces, or two separate domains with the same interface:
# [ptp_domain 0]
# interfaces ens1f0np0
[ptp_domain 127]
interfaces ens1f0np0 ens1f1np1
$ sudo timemaster -m -q -f minimal_timemaster.conf
timemaster[533042.285]: process 2755518 started: chronyd -n -f
/var/run/timemaster/chrony.conf
timemaster[533042.285]: process 2755520 started: phc2sys -l 5 -a -r -R 1.00 -z
/var/run/timemaster/ptp4l.0.socket -t [127:ens1f0np0] -n 127 -E refclock_sock
--refclock_sock_address /var/run/timemaster/chrony.SOCK0
timemaster[533042.286]: process 2755522 started: phc2sys -l 5 -a -r -R 1.00 -z
/var/run/timemaster/ptp4l.1.socket -t [127:ens1f1np1] -n 127 -E refclock_sock
--refclock_sock_address /var/run/timemaster/chrony.SOCK1
Fatal error : Could not open socket /var/run/timemaster/chrony.SOCK1
...
Quickfix:
sudo sed -i 's|@{run}/timemaster/chrony.SOCK0
rw,|@{run}/timemaster/chrony.SOCK[0-9]* rw,|' /etc/apparmor.d/usr.sbin.chronyd
sudo systemctl reload apparmor
Expected output:
The timemaster command continues to run until pressing CTRL+C
$ lsb_release -rd
