2013-11-08Remove dead code and unexport some callsLennart Poettering
"make check-api-unused" informs us about code that is not used anymore or that is exported but only used internally. Fix these all over the place.
2013-11-05logind: port logind to libsystemd-busLennart Poettering
2013-09-17logind: rename vtconsole to seat0David Herrmann
The seat->vtconsole member always points to the default seat seat0. Even if VTs are disabled, it's used as default seat. Therefore, rename it to seat0 to correctly state what it is. This also changes the seat files in /run from IS_VTCONSOLE to IS_SEAT0. It wasn't used by any code, yet, so this seems fine. While we are at it, we also remove every "if (s->vtconsole)" as this pointer is always valid!
2013-09-17logind: add infrastructure to watch busnamesDavid Herrmann
If we want to track bus-names to allow exclusive resource-access, we need a way to get notified when a bus-name is gone. We make logind watch for NameOwnerChanged dbus events and check whether the name is currently watched. If it is, we remove it from the watch-list (notification for other objects can be added in follow-up patches).
2013-09-17logind: listen actively for session devicesDavid Herrmann
Session compositors need access to fbdev, DRM and evdev devices if they control a session. To make logind pass them to sessions, we need to listen for them actively. However, we avoid creating new seats for non master-of-seat devices. Only once a seat is created, we start remembering all other session devices. If the last master-device is removed (even if there are other non-master devices still available), we destroy the seat. This is the current behavior, but we need to explicitly implement it now as there may be non-master devices in the seat->devices list. Unlike master devices, we don't care whether our list of non-master devices is complete. We don't export this list but use it only as cache if sessions request these devices. Hence, if a session requests a device that is not in the list, we will simply look it up. However, once a session requested a device, we must be notified of "remove" udev events. So we must link the devices somehow into the device-list. Regarding the implementation, we now sort the device list by the "master" flag. This guarantees that master devices are at the front and non-master devices at the tail of the list. Thus, we can easily test whether a seat has a master device attached.
2013-08-13logind: restore logic to kill user processes when session endsLennart Poettering
2013-07-10user-sessions: rely on PID 1 to kill sessionsLennart Poettering
As we want to centralized cgroup access we should stop killing the user sessions directly from the systemd-user-sessions service. Instead, rely on PID 1 doing this by adding the right ordering dependencies to the session scope units.
2013-07-02machined: split out machine registration stuff from logindLennart Poettering
Embedded folks don't need the machine registration stuff, hence it's nice to make this optional. Also, I'd expect that machinectl will grow additional commands quickly, for example to join existing containers and suchlike, hence it's better keeping that separate from loginctl.
2013-07-02logind: port over to use scopes+slices for all cgroup stuffLennart Poettering
In order to prepare things for the single-writer cgroup scheme, let's make logind use systemd's own primitives for cgroup management. Every login user now gets his own private slice unit, in which his sessions live in a scope unit each. Also, add user@$UID.service to the same slice, and implicitly start it on first login.
2013-06-20logind: add infrastructure to keep track of machines, and move to slicesLennart Poettering
- This changes all logind cgroup objects to use slice objects rather than fixed croup locations. - logind can now collect minimal information about running VMs/containers. As fixed cgroup locations can no longer be used we need an entity that keeps track of machine cgroups in whatever slice they might be located. Since logind already keeps track of users, sessions and seats this is a trivial addition. - nspawn will now register with logind and pass various bits of metadata along. A new option "--slice=" has been added to place the container in a specific slice. - loginctl gained commands to list, introspect and terminate machines. - user.slice and machine.slice will now be pulled in by logind.service, since only logind.service requires this slice.
2013-01-25logind: rework delay inhibition logicLennart Poettering
- Don't allow any locks to be taken while we are in the process of executing the specific operation, so that apps are not surprised if a suspend/shutdown happens while they rely on their inhibitor. - Get rid of the Resumed signal, it was a bad idea, and redundant due to PrepareForSleep(false), see below. - Always send out PrepareFor{Shutdown,Sleep} signals, instead of only if a delay lock is taken. - Move PrepareForSleep(false) after we come back from the suspend, so that apps can use this as "Resumed" notification. This also has the benefit that apps know when to take a new lock.
2013-01-24logind: send Resumed() signal after we come back from ↵Lennart Poettering
suspend/hibernate/hybrid-sleep This allows clients to get asynchronous notifications for user-requested suspend/hibernate cycles. Kernel-triggered automatic suspending is not covered.
2013-01-24logind: only allow one shutdown/sleep action to be queued at the same timeLennart Poettering
This should make sure that closing the lid while shutting down won't suspend the machine but will simply cause the shutdown to complete.
2012-12-24logind: add support for automatic suspend/hibernate/shutdown on idleLennart Poettering
2012-09-21logind: split up HandleSleepKey= into HandleSuspendKey= and HandleHibernateKey=Lennart Poettering
The kernel and X11 distuingish these two, and Thinkpad keys have both, hence we really should distinguish them too.
2012-09-19logind: rework power key/suspend key/lid switch handlingLennart Poettering
http://lists.freedesktop.org/archives/systemd-devel/2012-September/006604.html https://bugzilla.gnome.org/show_bug.cgi?id=680689 This changes the meaning of the HandlePowerKey=/HandleSleepKey=/HandleLidSwitch= setting of logind.conf
2012-09-17logind: make sure there's always a getty available on TTY6Lennart Poettering
Previously, if X allocated all 6 TTYs (for multi-session for example) no getty would be available anymore to guarantee console-based logins. With the new ReserveVT= switch in logind.conf we can now choose one VT (6 by default) that will always be subject to autovt-style activation, i.e. we'll always have a getty on TTY6, and X will never take possession of it.
2012-07-19use #pragma once instead of foo*foo #define guardsShawn Landden
#pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported in other compilers. I've been using and maintaining (rebasing) this patch for a while now, as it annoyed me to see #ifndef fooblahfoo, etc all over the place, almost arrogant about the annoyance of having to define all these names to perform a commen but neccicary functionality, when a completely superior alternative exists. I havn't sent it till now, cause its kindof a style change, and it is bad voodoo to mess with style that has been established by more established editors. So feel free to lambast me as a crazy bafoon. v2 - preserve externally used headers
2012-05-31logind: properly clean up user cgroups when they run emptyLennart Poettering
2012-05-30logind: optionally handle power, sleep and lid switch eventsLennart Poettering
This takes handling of chassis power and sleep keys as well as the lid switch over from acpid. This logic is enabled by default for power and sleep keys, but not for the lid switch. If a graphical session is in the foreground no action is taken under the assumption that the graphical session does this.
2012-05-08logind: implement suspend/hibernate calls with inhibition logicLennart Poettering
2012-05-05logind: implement delay inhibitor locks in addition to block inhibitor locksLennart Poettering
This is useful to allow applications to synchronously save data before the system is suspended or shut down.
2012-04-16logind: add shutdown/suspend/idle inhibition frameworkLennart Poettering
2012-04-12relicense to LGPLv2.1 (with exceptions)Lennart Poettering
We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.
