* udevd: update snippet stringZbigniew Jędrzejewski-Szmek2020-05-301-1/+1
| | | | | Repeating the unit name in the description is not useful, and "manages devices" is too cryptic.
* Merge pull request #15942 from poettering/pass-pktinfoYu Watanabe2020-05-291-1/+1
|\ | | | | disable PassCredentials= on networkd netlink socket, enable NETLINK_PKTINFO instead
| * networkd: clean up NETLINK_PKTINFO vs. SO_PASSCRED confusionLennart Poettering2020-05-271-1/+1
| | | | | | | | | | | | | | | | | | We actually care for NETLINK_PKTINFO, not for SO_PASSCRED, hence when allocating the netlink socket, configure things accordingly. Tracked down by Benjamin Robin, see: https://github.com/systemd/systemd/pull/15571#issuecomment-633213747
* | homed: enable userdb too if homed is requestedLennart Poettering2020-05-281-0/+1
|/ | | | | | | | | | | | | | Strictly speaking you can run homed without userdb. But it doesn't really make much sense: they go hand in hand and implement the same concepts, just for different sets of users. Let's hence disable both automatically by default if homed is requested. (We don't do the reverse: opting into userdbd shouldn't mean that you are OK with homed.) And of course, users can always deviate from our defaults easily, and turn off userbd again right-away if they don't like it, and things will generally work.

|\ | | | | xdg-autostart-generator: a generator for XDG autostart files
| * xdg-autostart-generator: Add a generator for XDG autostart filesBenjamin Berg2020-05-272-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This generator can be used by desktop environments to launch autostart applications and services. The feature is an opt-in, triggered by xdg-desktop-autostart.target being activated. Also included is the new binary xdg-autostart-condition. This binary is used as an ExecCondition to test the OnlyShowIn and NotShowIn XDG desktop file keys. These need to be evaluated against the XDG_CURRENT_DESKTOP environment variable which may not be known at generation time. Co-authored-by: Henri Chain <henri.chain@enioka.com>
* | units: remove KillMode=process in our regular gettysLennart Poettering2020-05-264-0/+8
|/ | | | | | | In our regular gettys the actual shell commands live the the session scope anyway (as long as logind is used). Hence, let's avoid KillMode=process, it serves no purpose and is simply unsafe since it disables systemd's own process lifecycle management.
* units: don't set PrivateNetwork= in systemd-homed.serviceLennart Poettering2020-05-261-1/+0
| | | | | | | | | We want to watch USB sticks being plugged in, and that requires AF_NETLINK to work correctly and get the host's events. But if we live in a network namespace AF_NETLINK is disconnected too and we'll not get the host udev events. Fixes: #15287

* tree-wide: add size limits for tmpfs mountsTopi Miettinen2020-05-131-1/+1
| | | | | | | | | | | | | | | | | Limit size of various tmpfs mounts to 10% of RAM, except volatile root and /var to 25%. Another exception is made for /dev (also /devs for PrivateDevices) and /sys/fs/cgroup since no (or very few) regular files are expected to be used. In addition, since directories, symbolic links, device specials and xattrs are not counted towards the size= limit, number of inodes is also limited correspondingly: 4MB size translates to 1k of inodes (assuming 4k each), 10% of RAM (using 16GB of RAM as baseline) translates to 400k and 25% to 1M inodes. Because nr_inodes option can't use ratios like size option, there's an unfortunate side effect that with small memory systems the limit may be on the too large side. Also, on an extremely small device with only 256MB of RAM, 10% of RAM for /run may not be enough for re-exec of PID1 because 16MB of free space is required.
* units: change description of systemd-logind.serviceZbigniew Jędrzejewski-Szmek2020-05-051-1/+1
| | | | | | "Login Service" doesn''t explain much, esp. considering that logind is actually is for logins. I think "User Login Management" is better, but not that great either. Suggestions welcome.
* binfmt: also unregister binfmt entries from unitLennart Poettering2020-04-231-0/+1
| | | | | | | | | | | | | | | | | | | | We unregister binfmt_misc twice during shutdown with this change: 1. A previous commit added support for doing that in the final shutdown phase, i.e. when we do the aggressive umount loop. This is the robust thing to do, in case the earlier ("clean") shutdown phase didn't work for some reason. 2. This commit adds support for doing that when systemd-binfmt.service is stopped. This is a good idea so that people can order mounts before the service if they want to register binaries from such mounts, as in that case we'll undo the registration on shutdown again, before unmounting those mounts. And all that, just because of that weird "F" flag the kernel introduced that can pin files... Fixes: #14981
* units: use correct path to refer to plymouthLennart Poettering2020-04-162-2/+2
| | | | | | | | | This doesn't really matter, since in non-/usr-merged systems plymouth needs to be in /bin and on merged ones it doesn't matter, but it is still prettier to insert the right path, and avoid /bin on merged systems, since it's just a compat symlink. Replaces: #15351
* units: make sure systemd-pstore stops at shutdownLennart Poettering2020-04-081-1/+2
| | | | | This doesn't matter too much given that the service doesn't do anything on shutdown, but let's still stop it to make things cleaner.
* units: drop systemd-remount-fs.service dependency from more servicesLennart Poettering2020-04-084-4/+3
| | | | | All services using StateDirectory= don't need the explicit dep anymore, let's hence drop it everywhere.
* units: drop dependency on systemd-remount-fs.service from systemd-pstore.serviceLennart Poettering2020-04-081-2/+0
| | | | | | | | This dependency is now generated automatically given we use StateDirectory=. Moreover the combination of Wants= and After= was too strong anway, as whether remount-fs is pulled in or not should not be up to systemd-pstore.service, and in fact is part of the initial transaction anyway.
* units: pull in systemd-pstore.service from sysinit.targetLennart Poettering2020-04-081-1/+2
| | | | | | | | sysinit.target is the target our early boot services are generally pulled in from, make systemd-pstore.service not an exception of that. Effectively this doesn't mean much, either way our unit is part of the initial transaction.
* units: add ProtectClock=yesTopi Miettinen2020-04-076-0/+8
| | | | | | Add `ProtectClock=yes` to systemd units. Since it implies certain `DeviceAllow=` rules, make sure that the units have `DeviceAllow=` rules so they are still able to access other devices. Exclude timesyncd and timedated.
* units: run systemd-repart only if there's configuration for itLennart Poettering2020-04-021-0/+4

* Revert "units: make systemd-repart.service installable"Lennart Poettering2020-04-022-5/+2
| | | | | | | | | | | | | | | | | | | | This reverts commit 7e1ed1f3b29162df25064b33dc55ac8cf432bb0b. systemd-repart is not a user service that should be something people enable/disable, instead it should just work if there's configuration for it. It's like systemd-tmpfiles, systemd-sysusers, systemd-load-modules, systemd-binfmt, systemd-systemd-sysctl which are NOPs if they have no configuration, and thus don't hurt, but cannot be disabled since they are too deep part of the OS. This doesn't mean people couldn't disable the service if they really want to, there's after all "systemctl mask" and build-time disabling, but those are OS developer facing instead of admin facing, that's how it should be. Note that systemd-repart is in particular an initrd service, and so far enable/disable state of those is not managed anyway via "systemctl enable/disable" but more what dracut decides to package up and what not.

| | | | | | | | | | | | | | | | It's lightweight and generally useful, so it should be enabled by default. But users might want to disable it for whatever reason, and things should be fine without it, so let's make it installable so it can be disabled if wanted. Fixes #15175.

| * units: make systemd-repart.service installableZbigniew Jędrzejewski-Szmek2020-03-312-3/+6
| | | | | | | | | | | | This essentially adds another layer of configurability: build disable, this, presence of configuration. The default is set to enabled, because the service does nothing w/o config.

|/ | | | | | | | | /home is posibly a remote file system. it makes sense to order homed after it, so that we can properly enumerate users in it, but we probably shouldn't pull it in ourselves, and leave that to users to configure otherwise. Fixes: #15102

| * units: restore RemainAfterExit=yes in systemd-vconsole-setup.serviceZbigniew Jędrzejewski-Szmek2020-03-051-0/+1
| | | | | | | | | | | | | | | | | | | | This reverts the second part of 8125e8d38e3aa099c7dce8b0161997b8842aebdc. The first part was reverted in 750e550eba362096d56a35104c6a32631aa67b8e. The problem starts when s-v-s.s is pulled in by something that is then pulled in by sysinit.target. Every time a unit is started, systemd recursively checks all dependencies, and since sysinit.target is pull in by almost anything, we'll start s-v-s.s over and over. In particular, plymouth-start.service currently has Wants=s-v-s.s and After=s-v-s.s.
* | units: skip modprobe@.service if the unit appears to be already loadedZbigniew Jędrzejewski-Szmek2020-03-051-0/+1
| | | | | | | | | | | | | | | | Possible alternative to #14819. For me, setting RemainAfterExit=yes would be OK, but if people think that it might cause issues, then this could be a reasonable alternative that still let's us skip the invocation of the separate binary.

* | units: do not ignore return value from systemd --userZbigniew Jędrzejewski-Szmek2020-03-051-1/+1
|/ | | | | | | | | | | | | | | | | | | This minus has been there since the unit was added in d42d27ead91e470cb12986d928441e56c0f543ca. I think the idea was not cause things to fail if the user instance doesn't work. But ignoring the return value doesn't seem to be the right way to approach the problem. In particular, if the program fails to run, we'll get a bogus fail state, see https://bugzilla.redhat.com/show_bug.cgi?id=1727895#c1: with the minus: $ systemctl start user@1002 Job for user@1002.service failed because the service did not take the steps required by its unit configuration. See "systemctl status user@1002.service" and "journalctl -xe" for details. without the minus: $ systemctl start user@1002 Job for user@1002.service failed because the control process exited with error code. See "systemctl status user@1002.service" and "journalctl -xe" for details.
* RequireMountsFor in systemd-nspawn should wait for machine mountKevin P. Fleming2020-03-021-1/+1

* units: disable ProtectKernelLogs for machinedGuillaume Douézan-Grard2020-03-021-1/+0
| | | | | | | | | | | machined needs access to the host mount namespace to propagate bind mounts created with the "machinectl bind" command. However, the "ProtectKernelLogs" directive relies on mount namespaces to make the kernel ring buffer inaccessible. This commit removes the "ProtectKernelLogs=yes" directive from machined service file introduced in 6168ae5. Closes #14559.

| | | | | | | | | | | Kernel 4.1 separated the tracing system from the debugfs, actual documentation already points to a different path that needs this new mount to exist. the old sysfs path will still be an automount in the debugfs, created by the kernel (for now).
