Thanks for the ping on this @ahresse ! Yes, this should be very similar to thew old fix in bug 1771028
It is essentially yet another "chrony works with something else" use case. There is a section for that in the chrony apparmor rules and we should indeed add the known default paths (like this) to be allowed. And this is such a default path, from the man page: rundir - Specify the directory where should be generated chronyd, ntpd and ptp4l configuration files and sockets. The directory will be created if it doesn't exist. The default value is /var/run/timemaster. So on this we might even want to allow to read all sub-elements, including the generated config. But RW for the socket. But furthermore while touching it, in addition to the one reported I also see in the ptp4l refclock_sock_address - The address of the UNIX domain socket to be used by the refclock_sock servo. The default is /var/run/refclock.ptp.sock So we should allow that path as well. For chrony my proposal that - once agreed - we need to pick up would seem like diff --git a/debian/usr.sbin.chronyd b/debian/usr.sbin.chronyd index bc52d4f7..e64edc90 100644 --- a/debian/usr.sbin.chronyd +++ b/debian/usr.sbin.chronyd @@ -62,6 +62,13 @@ abi <abi/3.0>, @{run}/chrony.*.sock rw, # To sign replies to MS-SNTP clients by the smbd daemon /var/lib/samba/ntp_signd/socket rw, + # default path of the sock to sync with ptp4l + @{run}/refclock.ptp.sock rw, + # timemaster directory of chronyd, ... configuration files and sockets. + # read for all configs + @{run}/timemaster/* r, + # rw for coodination via the default socket path + @{run}/timemaster/chrony.SOCK0 rw, # rtc /etc/adjtime r, -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2032805 Title: Could not open socket /var/run/timemaster/chrony.SOCK0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chrony/+bug/2032805/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
