[Touch-packages] [Bug 1774788] Re: Daemon won't start at boot up (18LTS fully patched)
When rsyncd cannot find the address it was told to bind to, it exits with rc=10 and systemd doesn't even attempt a restart. To make it restart on such condition, the systemd unit should have `Restart=on-failure` added. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1774788 Title: Daemon won't start at boot up (18LTS fully patched) Status in rsync: Unknown Status in rsync package in Ubuntu: Won't Fix Bug description: By adding the 'address=' option to the /etc/rsyncd.conf file, the daemon fails at boot.

[Touch-packages] [Bug 1774788] Re: Daemon won't start at boot up (18LTS fully patched)
This is a class[1] of bugs for which we cannot come up with a general solution that will safely and sanely apply to all scenarios. For such cases, local configuration changes should be made to accommodate the intended behavior in each case. We believe that, in this particular case, since the configuration was explicitly changed to use a specific IP, you should continue with the changes and adjust the systemd unit file for rsync to cope with that. Be it adjust the target to be network-online, or something else that explicitly waits for that very interface to come up. systemd offers mechanisms for such overrides, and it's described in more detail in comment #2. Regarding the "systemctl start rsync" exit status, it's the way it work with Type=simple systemd services. From the systemd.service manpage: """ If set to simple (the default if ExecStart= is specified but neither Type= nor BusName= are) the service manager will consider the unit started immediately after the main service process has been forked off. (...) Note that this means systemctl start command lines for simple services will report success even if the service's binary cannot be invoked successfully """ I tried Type=exec, but it still behaved in the same way (as the error happens after rsync starts up, i.e., the binary was executed). With Type=forking I got a bit further, but the timeout needs tuning: root@j1-rsyncd:~# time systemctl start rsync Job for rsync.service failed because a timeout was exceeded. See "systemctl status rsync.service" and "journalctl -xeu rsync.service" for details. real1m30.246s With TimeoutStartSec=5 in the unit file it's better: root@j1-rsyncd:~# time systemctl start rsync Job for rsync.service failed because a timeout was exceeded. See "systemctl status rsync.service" and "journalctl -xeu rsync.service" for details. real0m5.287s I think the most reliably way would be Type=notify, but that requires rsync code changes to support systemd's notify mechanism. In summary, for the specific case of this bug, we believe that systemd overrides are the best answer for now. To detect startup errors immediately, I'm willing to file a separate bug. 1. https://bugs.launchpad.net/ubuntu/+bugs?field.tag=network-online-ordering ** Changed in: rsync (Ubuntu) Status: Triaged => Won't Fix -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1774788 Title: Daemon won't start at boot up (18LTS fully patched) Status in rsync: Unknown Status in rsync package in Ubuntu: Won't Fix Bug description: By adding the 'address=' option to the /etc/rsyncd.conf file, the daemon fails at boot.

[Touch-packages] [Bug 1774788] Re: Daemon won't start at boot up (18LTS fully patched)
Upstream seems to disagree with the IP_FREEBIND implementation, as per https://bugzilla.samba.org/show_bug.cgi?id=13463. The reason behind it is that the daemon should fail for invalid ip addresses. Adding After=network-online.target is frowned upon by systemd upstream. Following up with upstream to exit with a non-zero code seems to be the path forward here. ** Tags added: server-todo -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1774788 Title: Daemon won't start at boot up (18LTS fully patched) Status in rsync: Unknown Status in rsync package in Ubuntu: Triaged Bug description: By adding the 'address=' option to the /etc/rsyncd.conf file, the daemon fails at boot.

[Touch-packages] [Bug 1774788] Re: Daemon won't start at boot up (18LTS fully patched)
The default behaviour of these services is to bind to "0.0.0.0", which means "any IP" essentially. That means they will work even when the nic isn't there yet, because localhost is. It also means that once a new nic comes up, they will listen on all its addresses too, without any other changes in configuration or restarts. Same for when an address disappears. It's definitely a good default for network services. The moment you tell a service to bind to a specific IP, however, if that IP is not available then it will fail. That's where IP_FREEBIND comes in. It requires code changes, though. This systemd upstream article talks about the pros and cons of depending on network-online.target: https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget/. In general, it should be avoided if possible. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1774788 Title: Daemon won't start at boot up (18LTS fully patched) Status in rsync: Unknown Status in rsync package in Ubuntu: Triaged Bug description: By adding the 'address=' option to the /etc/rsyncd.conf file, the daemon fails at boot.

[Touch-packages] [Bug 1774788] Re: Daemon won't start at boot up (18LTS fully patched)
Thanks for filing this bug in Ubuntu. The scenario is confirmed: when specifying an address to bind to, rsync will fail if that address is not available: /var/log/syslog:Jun 4 21:12:27 bionic-rsync-1774788 rsyncd[269]: rsyncd version 3.1.2 starting, listening on port 873 /var/log/syslog:Jun 4 21:12:27 bionic-rsync-1774788 rsyncd[269]: bind() failed: Cannot assign requested address (address-family 2) /var/log/syslog:Jun 4 21:12:27 bionic-rsync-1774788 rsyncd[269]: unable to bind any inbound sockets on port 873 /var/log/syslog:Jun 4 21:12:27 bionic-rsync-1774788 rsyncd[269]: rsync error: error in socket IO (code 10) at socket.c(555) [Receiver=3.1.2] The solution seems to be for rsync to adopt the socket option IP_FREEBIND. >From the ip(7) manpage: IP_FREEBIND (since Linux 2.4) If enabled, this boolean option allows binding to an IP address that is nonlocal or does not (yet) exist. This per‐ mits listening on a socket, without requiring the underlying network interface or the specified dynamic IP address to be up at the time that the application is trying to bind to it. This option is the per-socket equivalent of the ip_nonlo‐ cal_bind /proc interface described below. Until then, one workaround would be to configure the service file for rsyncd to wait for the network to be online. If you run: sudo systemctl edit rsync.service It will open an editor. Put these lines in: [Unit] After=network.target,network-online.target Then save. That will create /etc/systemd/system/rsync.service.d/override.conf with the two lines above. Alternatively you can just create the file above directly with the specified content without going through "systemctl edit". You can then reboot and see if that helps. Note that the job will fail, after reaching the network-online target, if you specify an IP address that doesn't exist at that stage. Another option I saw in https://unix.stackexchange.com/questions/442181 /sshd-failed-due-to-network-not-yet-available but haven't tested is to make a system-wide change in /proc. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1774788 Title: Daemon won't start at boot up (18LTS fully patched) Status in rsync package in Ubuntu: New Bug description: By adding the 'address=' option to the /etc/rsyncd.conf file, the daemon fails at boot.
