2014-08-18core: Verify systemd1 DBus method callers via polkitStef Walter
DBus methods that retrieve information can be called by anyone. DBus methods that modify state of units are verified via polkit action: org.freedesktop.systemd1.manage-units DBus methods that modify state of unit files are verified via polkit action: org.freedesktop.systemd1.manage-unit-files DBus methods that reload the entire daemon state are verified via polkit action: org.freedesktop.systemd1.reload-daemon DBus methods that modify job state are callable from the clients that started the job. root (ie: CAP_SYS_ADMIN) can continue to perform all calls, property access etc. There are several DBus methods that can only be called by root. Open up the dbus1 policy for the above methods. (Heavily modified by Lennart, making use of the new bus_verify_polkit_async() version that doesn't force us to always pass the original callback around. Also, interactive auhentication must be opt-in, not unconditional, hence I turned this off.)
2014-03-03bus: add sd_bus_track object for tracking peers, and port core over to itLennart Poettering
This is primarily useful for services that need to track clients which reference certain objects they maintain, or which explicitly want to subscribe to certain events. Something like this is done in a large number of services, and not trivial to do. Hence, let's unify this at one place. This also ports over PID 1 to use this to ensure that subscriptions to job and manager events are correctly tracked. As a side-effect this makes sure we properly serialize and restore the track list across daemon reexec/reload, which didn't work correctly before. This also simplifies how we distribute messages to broadcast to the direct busses: we only track subscriptions for the API bus and implicitly assume that all direct busses are subscribed. This should be a pretty OK simplification since clients connected via direct bus connections are shortlived anyway.
2013-11-20core: convert PID 1 to libsystemd-busLennart Poettering
This patch converts PID 1 to libsystemd-bus and thus drops the dependency on libdbus. The only remaining code using libdbus is a test case that validates our bus marshalling against libdbus' marshalling, and this dependency can be turned off. This patch also adds a couple of things to libsystem-bus, that are necessary to make the port work: - Synthesizing of "Disconnected" messages when bus connections are severed. - Support for attaching multiple vtables for the same interface on the same path. This patch also fixes the SetDefaultTarget() and GetDefaultTarget() bus calls which used an inappropriate signature. As a side effect we will now generate PropertiesChanged messages which carry property contents, rather than just invalidation information.
2013-07-10core: send out "Reloading" signal before and after doing a full ↵Lennart Poettering
reload/reexec of PID 1 Since we'll unload all units/job during a reload, and then readd them it is really useful for clients to be aware of this phase hence sent a signal out before and after. This signal is called "Reloading" (despite the fact that it is also sent out during reexecution, which we consider a special case in this context) and has one boolean parameter which is true for the signal sent before the reload, and false for the signal after the reload. The UnitRemoved/JobRremoved and UnitNew/JobNew due to the reloading are guranteed to be between the pair of Reloading messages.

2012-09-13manager: extend performance measurement interface to include firmware/loader ↵Lennart Poettering
times This only adds the fields to the D-Bus interfaces but doesn't fill them in with anything useful yet. Gummiboot exposes the necessary bits of information to use however and as soon as I get my fingers on a proper UEFI laptop I'll hook up the remaining bits. Since we want to stabilize the D-Bus interface soon and include it in the stability promise we should get the last fixes in, hence this change now.
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
2012-04-12relicense 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.
