* Prep v226: Apply missing fixes and changes to src/loginSven Eden2017-03-14

* property callback returns are consistentUmut Tezduyar Lindskog2017-03-14
| | | | | | | It is no different to return 0 over 1 in the property callback. It is confusing to return 1 which made me think 1 has a special purpose. This way code is consistent with the rest of the tree.
* everywhere: actually make use of DUAL_TIMESTAMP_NULL macroLennart Poettering2017-03-14
| | | | Let's use it as initializer where appropriate.
* sd-bus: drop bus parameter from message callback prototypeLennart Poettering2017-03-14
| | | | | | This should simplify the prototype a bit. The bus parameter is redundant in most cases, and in the few where it matters it can be derived from the message via sd_bus_message_get_bus().
* shared: add formats-util.hRonny Chevalier2017-03-14
|
* logind: open up most bus calls for unpriviliged processes, using PolicyKitLennart Poettering2015-02-18
| | | | | | Also, allow clients to alter their own objects without any further priviliges. i.e. this allows clients to kill and lock their own sessions without involving PK.
* logind: hide 'self' links if not availableDavid Herrmann2015-01-18
| | | | | | | If the caller does not run in a session/seat or has no tracked user, hide the /org/freedesktop/login1/.../self links in introspection data. Otherwise, "busctl tree org.freedesktop.login1" tries to query those nodes even though it cant.
* logind: unify how we cast between uid_t and pointers for hashmap keysLennart Poettering2015-01-09
|
* logind: when a bus call is done on a session, user or seat, optionally ↵Lennart Poettering2015-01-09
| | | | | | | | | | determine them from the caller credentials More specifically, if an operation is requested on a session with an empty name, the caller's session is used. If an operation is requested on a seat with an empty name, the seat of the caller's session is used. Finally, if an operation on the user with UID -1 is requested, the user of the client's session is used (and not the UID of the client!).
* logind: include "self" object links in dbus introspectionLennart Poettering2015-01-09
| | | | Makes "busctl introspect" a lot more fun.
* logind: remove spurious include of <sys/capability.h>Filipe Brandenburger2014-12-25
| | | | | | | | | | They do not use any functions from libcap directly. The CAP_* constants in use through these files come from "missing.h" which will import <linux/capability.h> and complement it with CAP_* constants not defined by the current kernel headers. The "missing.h" header is imported through "util.h" which gets imported in "logind.h". Tested that "systemd-logind" builds cleanly and works after this change.
* logind: fix Display property of user objectsLennart Poettering2014-05-19
| | | | | | | | When we dropped support for creating a per-user to the "main" X11 display we stopped returning useful data in the "Display" user property. With this change this is fixed and we again expose an appropriate (graphical session) in the property that is useful as the "main" one, if one is needed.
* Remove unnecessary casts in printfsZbigniew Jędrzejewski-Szmek2014-05-15
| | | | No functional change expected :)
* sd-bus: introduce sd_bus_slot objects encapsulating callbacks or vtables ↵Lennart Poettering2014-05-15
| | | | | | | | | | | attached to a bus connection This makes callback behaviour more like sd-event or sd-resolve, and creates proper object for unregistering callbacks. Taking the refernce to the slot is optional. If not taken life time of the slot will be bound to the underlying bus object (or in the case of an async call until the reply has been recieved).
* Introduce strv_consume which takes ownershipZbigniew Jędrzejewski-Szmek2014-03-04
| | | | This mirrors set_consume and makes the common use a bit nicer.
* logind: always kill session when termination is requestedZbigniew Jędrzejewski-Szmek2014-02-11
| | | | | KillUserProcesses=yes/no should be ignored when termination is explicitly requested.
* bus: decorate the various object vtables with SD_BUS_VTABLE_PROPERTY_CONST ↵Lennart Poettering2013-12-22
| | | | where appropriate
* bus: introduce "trusted" bus concept and encode access control in object vtablesLennart Poettering2013-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduces a new concept of "trusted" vs. "untrusted" busses. For the latter libsystemd-bus will automatically do per-method access control, for the former all access is automatically granted. Per-method access control is encoded in the vtables: by default all methods are only accessible to privileged clients. If the SD_BUS_VTABLE_UNPRIVILEGED flag is set for a method it is accessible to unprivileged clients too. By default whether a client is privileged is determined via checking for its CAP_SYS_ADMIN capability, but this can be altered via the SD_BUS_VTABLE_CAPABILITY() macro that can be ORed into the flags field of the method. Writable properties are also subject to SD_BUS_VTABLE_UNPRIVILEGED and SD_BUS_VTABLE_CAPABILITY() for controlling write access to them. Note however that read access is unrestricted, as PropertiesChanged messages might send out the values anyway as an unrestricted broadcast. By default the system bus is set to "untrusted" and the user bus is "trusted" since per-method access control on the latter is unnecessary. On dbus1 busses we check the UID of the caller rather than the configured capability since the capability cannot be determined without race. On kdbus the capability is checked if possible from the attached meta-data of a message and otherwise queried from the sending peer. This also decorates the vtables of the various daemons we ship with these flags.
* bus: add new sd_bus_creds object to encapsulate process credentialsLennart Poettering2013-11-28
| | | | | | | | | | | | | This way we can unify handling of credentials that are attached to messages, or can be queried for bus name owners or connection peers. This also adds the ability to extend incomplete credential information with data from /proc, Also, provide a convenience call that will automatically determine the most appropriate credential object for an incoming message, by using the the attached information if possible, the sending name information if available and otherwise the peer's credentials.
* bus: also add error parameter to object find and enumerator callbacksLennart Poettering2013-11-22
| | | | | Just in order to bring things inline with the method and property callbacks.
* bus: rework message handlers to always take an error argumentLennart Poettering2013-11-21
| | | | | | | | | | | | | | | | | | | | Message handler callbacks can be simplified drastically if the dispatcher automatically replies to method calls if errors are returned. Thus: add an sd_bus_error argument to all message handlers. When we dispatch a message handler and it returns negative or a set sd_bus_error we send this as message error back to the client. This means errors returned by handlers by default are given back to clients instead of rippling all the way up to the event loop, which is desirable to make things robust. As a side-effect we can now easily turn the SELinux checks into normal function calls, since the method call dispatcher will generate the right error replies automatically now. Also, make sure we always pass the error structure to all property and method handlers as last argument to follow the usual style of passing variables for return values as last argument.
* bus: let's simplify things by getting rid of unnecessary bus parametersLennart Poettering2013-11-21
|
* logind: add virtual object paths that always can be used to refer to the ↵Lennart Poettering2013-11-05
| | | | | | | callers session, user, seat or machine object This way clients can skip invoking GetSessionByPID() for their own PID or a similar call to access these objects.
* logind: expose linger state on User objectLennart Poettering2013-11-05
|
* logind: port logind to libsystemd-busLennart Poettering2013-11-05
|
* logind: port over to use scopes+slices for all cgroup stuffLennart Poettering2013-07-02
| | | | | | | | | 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.
* logind: add infrastructure to keep track of machines, and move to slicesLennart Poettering2013-06-20
| | | | | | | | | | | | | | | | | | | | - 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.

* Use bus_maybe_send_reply() where applicableColin Walters2013-03-18
| | | | | | | | | This is a followup to: commit 1a37b9b9043ef83e9900e460a9a1fccced3acf89 It will fix denial messages from dbus-daemon between gdm and systemd-logind on logging into GNOME due to this. See the previous commit for more details.
* udev: replace util_create_path() with mkdir_parents()Kay Sievers2012-04-17
|
* systemctl: show main and control PID explicitly in cgroup-showLennart Poettering2012-04-16
| | | | | | | In some cases the main/control PID of a service can be outside of the services cgroups (for example, if logind readjusts the processes' cgroup). In order to clarify this for the user show the main/control PID in the cgroup tree nonetheless, but mark them specially.
* relicense to LGPLv2.1 (with exceptions)Lennart Poettering2012-04-12
| | | | | | | | | | | | | | 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.
* dbus: more efficient implementation of propertiesMichal Schmidt2012-01-16
| | | | | | | | | | | | | | | | | The way the various properties[] arrays are initialized is inefficient: - only the .data members change at runtime, yet the whole arrays of properties with all the fields are constructed on the stack one by one by the code. - there's duplication, eg. the properties of "org.freedesktop.systemd1.Unit" are repeated in several unit types. Fix it by moving the information about properties into static const sections. Instead of storing the .data directly in the property, store a constant offset from a run-time base. The small arrays of struct BusBoundProperties bind together the constant information with the right runtime information (the base pointer). On my system the code shrinks by 60 KB, data increases by 10 KB.
