* Prep v228: Removed EFI bits. elogind can not support EFI at all.Sven Eden2017-04-26
| | | | | | | Rebooting to firmware and such things are official init system stuff. The added system commands to loginctl like poweroff and reboot are a convenience, as any user can do it anyway using 'sudo shutdown' and similar commands.

* Prep v228: Add remaining updates from upstream (3/3)Sven Eden2017-04-26
| | | | | Apply remaining fixes and the performed move of utility functions into their own foo-util.[hc] files on the rest of elogind.
* login: ignore JobRemoved of old jobsDavid Herrmann2017-04-26
| | | | | | If we requeue jobs, we are no longer interested in old jobs. Hence, we better ignore any JobRemoved signals for old jobs and concentrate on our replacements.
* login: make sure to replace existing unitsDavid Herrmann2017-04-26
| | | | | | | When queuing unit jobs, we should rather replace existing units than fail. This is especially important when we queued a user-shutdown and a new login is encountered. In this case, we better raplce the shutdown jobs. elogind takes care of everything else.
* login: suspend - be a bit more explicit when loggingTom Gundersen2017-04-26
| | | | | | | | | | When the Suspend method is called, the only log message we write (unless debugging is enabled) is "Operation finished.". This is not very helpful when trying to figure out what is going on, so add what operation we are talking about to the message: "Operation 'sleep' finished.". Hat tip to Daniel Aleksandersen for pointing this out.

* Major cleanup of all leftovers after rebasing on master.Sven Eden2017-03-14
| | | | | | | | The patching of elogind in several steps with only partly rebasing on a common commit with upstream, left the tree in a state, that was unmergeable with master. By rebasing on master and manually cleaning up all commits, this merge is now possible. However, this process left some orphans, that are cleanup now.

* Remove support for auto-spawning VTsSven Eden2017-03-14
| | | | | Auto-spawning VTs requires systemd in practice. If you're using systemd you can just use its logind :)
* Remove dependency of systemd units, services and slices for new sessions.Sven Eden2017-03-14
| | | | | | | | | | | | | | | | | | | | * elogind does not support systemd services and units. But at least the units are needed to support the systemd cgroup slice/scope system. * Remove systemd subscription to scope, service and slice jobs. These can not be supported in any way, as they depend on systemd running the machine. * The functions session_start_scope(), user_start_service() and user_start_slice() no longer try to call systemd via dbus for assistance. This way they generate their proper scope, service and slice names, and store them in the Managers HashMaps for session and user units. This should enable us to reverse track pids to users and such stuff, as that is what systemd-logind does, not knowing whether any unit *really* has been started or not. However, this will not work out of the box until we find a way to integrate cg_create_everywhere() into elogind without becoming dependent of systemd unit, service and job knowledge again.

* Remove systemd subscription and user/session unitsAndy Wingo2017-03-14
| | | | | | This removes attempts by logind to listen to systemd messages over the bus, and to start and/or manage units associated with sessions and users.

* logind: fix write_string_file() falloutDaniel Mack2017-03-14
| | | | | | | | WRITE_STRING_FILE_ATOMIC is only valid if WRITE_STRING_FILE_CREATE is also given. IOW, an atomic file write operation is only possible when creating a file is also being asked for. This is a regression from the recent write_string_file() rework.
* logind: bring bus policy up-to-dateLennart Poettering2017-03-14
| | | | | | | | | | | | | A while back we opened up all of logind's bus calls to unprivileged users, via PK. However, the dbus1 policy wasn't updated accordingly. With this change, the dbus1 policy is opened up for all bus calls that should be available to unprivileged clients. (also rearranges some calls in the vtable, to make more sense, and be in line with the order in the bus policy file) Fixes #471.
* logind: allow greeters to take over VTsDavid Herrmann2017-03-14
| | | | | | | | Make sure a greeter can forcefully spawn a session on a VT that is in-use. A recent patch prevented this (this used to be possible for all session types) as it is highly fragile. However, as it turns out, greeters seem to rely on that feature. Therefore, make sure we allow it explicitly for greeters.
* logind: fail on CreateSession if already in sessionDavid Herrmann2017-03-14
| | | | | | | | | | | Right now, if you're already in a session and call CreateSession, we return information about the current session of yours. This is highy confusing and a nasty hack. Avoid that, and instead return a commonly known error, so the caller can detect that. This has the side-effect, that we no longer override XDG_VTNR and XDG_SEAT in pam_systemd, if you're already in a session. But this sounds like the right thing to do, anyway.
* logind: allow sessions to share a VT if it's a greeterDavid Herrmann2017-03-14
| | | | | | | | | | | | | | Old gdm and lightdm start the user-session during login before they destroy the greeter-session. Therefore, the user-session will take over the VT from the greeter. We recently prevented this by never allowing multiple sessions on the same VT. Fix this now, by explicitly allowing this if the owning session is a GREETER. Note that gdm no longer behaves like this. Instead, due to wayland, they always use a different VT for each session. All other login-managers are highly encouraged to destroy the greeter-session _before_ starting the user-session. We now work around this, but this will probably not last forever (and will already have nasty side-effects on the greeter-session).
* fileio: consolidate write_string_file*()Daniel Mack2017-03-14
| | | | | | | Merge write_string_file(), write_string_file_no_create() and write_string_file_atomic() into write_string_file() and provide a flags mask that allows combinations of atomic writing, newline appending and automatic file creation. Change all users accordingly.
* login: simplify assignmentZbigniew Jędrzejewski-Szmek2017-03-14

* login: re-use VT-sessions if they already existDavid Herrmann2017-03-14
| | | | | | | | | | | | | | | | | | | Right now, if you start a session via 'su' or 'sudo' from within a session, we make sure to re-use the existing session instead of creating a new one. We detect this by reading the session of the requesting PID. However, with gnome-terminal running as a busname-unit, and as such running outside the session of the user, this will no longer work. Therefore, this patch makes sure to return the existing session of a VT if you start a new one. This has the side-effect, that you will re-use a session which your PID is not part of. This works fine, but will break assumptions if the parent session dies (and as such close your session even though you think you're part of it). However, this should be perfectly fine. If you run multiple logins on the same session, you should really know what you're doing. The current way of silently accepting it but choosing the last registered session is just weird.
* logind: rework display counting when detecting whether the system is dockedLennart Poettering2017-03-14
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we'd just count connected displays, and if there was 2 or more we assumed a "docked" state. With this change we now: - Only count external displays, ignore internal ones (which we detect by checking the connector name against a whitelist of known external plug types) - We ignore connectors which are explicitly disabled - We then compare the count with >= 1 rather than >= 2 as before This new logic has the benefit that systems that disconnect the internal display when the lid is closed are better supported. Also, explicitly disabled ports do not confuse the algorithm anymore. This new algorithm has been suggested here: http://lists.freedesktop.org/archives/intel-gfx/2015-June/068821.html This also makes two functions static, that are not used outside of their .c files.
* everywhere: actually make use of DUAL_TIMESTAMP_NULL macroLennart Poettering2017-03-14
| | | | Let's use it as initializer where appropriate.
* logind: expose "Docked" bool as property on the busLennart Poettering2017-03-14
| | | | | We know the state anyway, let's expose it in the bus. It's useful for debugging at least, but it might be useful for DEs too.
* logind: fix delayed execution regressionDaniel Mack2017-03-14
| | | | | | | | | | | | | | | Commit c0f32805 ("logind: use sd_event timer source for inhibitor logic") reworked the main loop logic of logind so that it uses a real timeout callback handler to execute delayed functions. What the old code did, however, was to call those functions on every iteration in the main loop, not only when the timeout expired. Restore that behavior by bringing back manager_dispatch_delayed(), and call it from manager_run(). The internal event source callback manager_inhibit_timeout_handler() was turned into a wrapper of manager_dispatch_delayed() now.
* logind: Save the user’s state when a session enters SESSION_ACTIVEPhilip Withnall2017-03-14
| | | | | | | | | | | | | | | | | | | | | When (for example) switching from X11 to a new VT and logging in there, creating a new session, the user state file (/run/systemd/users/$uid) is not updated after the session becomes active. The latest time it is saved is when the session is in SESSION_OPENING. This results in a /run/systemd/users/$uid file which contains STATE=online for the current user on the current active VT, which is obviously wrong. As functions like sd_uid_get_state() use this file to get the user’s state, this could result in things like PolicyKit making incorrect decisions about the user’s state. (See https://bugs.freedesktop.org/show_bug.cgi?id=76358.) Fix this by re-saving the state for a session’s user after completing the state_job for that session. https://bugs.freedesktop.org/show_bug.cgi?id=90818
* logind: prefix some calls to unlink with (void)Daniel Mack2017-03-14
| | | | | Make Coverity happy and tell it we're not interested in the return value of these two calls.
* logind: unlink /run/nologin when shutdown is cancelledDaniel Mack2017-03-14
| | | | | When a scheduled is cancelled, make sure to remove /run/nologin. This is a regression from the recent shutdownd removal and logind rework.
* sd-bus: allow passing NULL as bus parameter to sd_bus_send()Lennart Poettering2017-03-14
| | | | | | | | If NULL is specified for the bus it is now automatically derived from the passed in message. This commit also changes a number of invocations of sd_bus_send() to make use of this.
