2015-06-02logind: Save the user’s state when a session enters SESSION_ACTIVEPhilip Withnall
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
2015-05-27logind: prefix some calls to unlink with (void)Daniel Mack
Make Coverity happy and tell it we're not interested in the return value of these two calls.
2015-05-27logind: unlink /run/nologin when shutdown is cancelledDaniel Mack
When a scheduled is cancelled, make sure to remove /run/nologin. This is a regression from the recent shutdownd removal and logind rework.
2015-04-29sd-bus: allow passing NULL as bus parameter to sd_bus_send()Lennart Poettering
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.
2015-04-29sd-bus: drop bus parameter from message callback prototypeLennart Poettering
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().
2015-04-24logind: kill newline characters from log_error_errno() callsDaniel Mack
log_error_errno() already adds a newline, so drop them.
2015-04-24logind: add support for /run/nologin and /run/systemd/shutdown/scheduledDaniel Mack
Port over more code from shutdownd and teach logind to write /run/nologin at least 5 minutes before the system is going down, and /run/systemd/shutdown/scheduled when a shutdown is scheduled.
2015-04-24logind: add code for UTMP wall messagesDaniel Mack
Add a timer to print UTMP wall messages so that it repeatedly informs users about a scheduled shutdown: * every 1 minute with less than 10 minutes to go * every 15 minutes with less than 60 minutes to go * every 30 minutes with less than 180 minutes (3 hours) to go * every 60 minutes if more than that to go This functionality only active if the .EnableWallMessages DBus property is set to true. Also, a custom string can be added to the wall message, set through the WallMessagePrefix property.
2015-04-24logind: add .ScheduleShutdown and .CancelScheduledShutdown methodsDaniel Mack
Add a method called ScheduleShutdown in org.freedesktop.login1.Manager which adds a timer to shut down the system at a later point in time. The first argument holds the type of the schedule that is about to happen, and must be one of 'reboot', 'halt' or 'poweroff'. The second argument specifies the absolute time, based on CLOCK_REALTIME in nanoseconds, at which the the operation should be executed. To cancel a previously scheduled shutdown, the CancelScheduledShutdown() can be called, which returns a bool, indicating whether a scheduled timeout was cancelled. Also add a new property called ScheduledShutdown which returns the equivalent to what was passed in via ScheduleShutdown, as '(st)' type.
2015-04-24logind: factor out polkit checksDaniel Mack
Factor out the code to ask polkit for authorization from method_do_shutdown_or_sleep() into an own function called verify_shutdown_creds(). This is needed in order to also use the same checks when shutdown operations are scheduled. For that, it's also necessary to allow NULL values for that action{,_multiple_sessions,_ignore_inhibit) arguments, which will suppress the call if no action string is passed.
2015-04-24logind: use sd_event timer source for inhibitor logicDaniel Mack
Instead of open-coding the delayed action and inhibit timeout logic, switch over to a real sd_event_source based implementation. This is not only easier to read but also allows us to add more timers in the future.

2015-04-07logind: drop "interactive" parameter from SetRebootToFirmwareSetup() bus callLennart Poettering
Newer dbus versions have an "allow interactive authentication" bit in the message header, hence it is not necessary to take a boolean for this explicitly.
2015-04-07logind,systemctl: add reboot to EFI firmware supportJan Janssen
2015-04-07polkit: rename bus_verify_polkit() to bus_test_polkit() and make it strictly ↵Lennart Poettering
non-interactive Interactive authorization should only happen asynchronously, hence disallow it in synchronous bus_verify_polkit(), and rename it to bus_test_polkit(). This way even if the bus message header asks for interactive authorization, we'll ask for non-interactive authorization which is actually the desired behaviour if CanSuspend, CanHibernate and friends, which call this function.
2015-03-15logind: check return value of session_releaseZbigniew Jędrzejewski-Szmek
It allocates memory, so it can fail. CID #1237527.
2015-03-06login: make hold-off timeout configurableDavid Herrmann
This introduces 'HoldoffTimeoutSec' to logind.conf to make IGNORE_LID_SWITCH_{SUSPEND,STARTUP}_USEC configurable. Background: If an external monitor is connected, or if the system is docked, we want to ignore LID events. This is required to support setups where a laptop is used with external peripherals while the LID is closed. However, this requires us to probe all hot-plugged devices before reacting to LID events. But with modern buses like USB, the standards do not impose any timeout on the slots, so we have no chance to know whether a given slot is used or not. Hence, after resume and startup, we have to wait a fixed timeout to give the kernel a chance to probe devices. Our timeout has always been generous enough to support even the slowest devices. However, a lot of people didn't use these features and wanted to disable the hold-off timer. Now we provide a knob to do that.
2015-02-23remove unused includesThomas Hindoe Paaboel Andersen
This patch removes includes that are not used. The removals were found with include-what-you-use which checks if any of the symbols from a header is in use.
2015-02-18logind: open up most bus calls for unpriviliged processes, using PolicyKitLennart Poettering
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.
2015-02-03util: rework strappenda(), and rename it strjoina()Lennart Poettering
After all it is now much more like strjoin() than strappend(). At the same time, add support for NULL sentinels, even if they are normally not necessary.

2015-01-18bus: use EUID over UID and fix unix-credsDavid Herrmann
Whenever a process performs an action on an object, the kernel uses the EUID of the process to do permission checks and to apply on any newly created objects. The UID of a process is only used if someone *ELSE* acts on the process. That is, the UID of a process defines who owns the process, the EUID defines what privileges are used by this process when performing an action. Process limits, on the other hand, are always applied to the real UID, not the effective UID. This is, because a process has a user object linked, which always corresponds to its UID. A process never has a user object linked for its EUID. Thus, accounting (and limits) is always done on the real UID. This commit fixes all sd-bus users to use the EUID when performing privilege checks and alike. Furthermore, it fixes unix-creds to be parsed as EUID, not UID (as the kernel always takes the EUID on UDS). Anyone using UID (eg., to do user-accounting) has to fall back to the EUID as UDS does not transmit the UID.
2015-01-09logind: unify how we cast between uid_t and pointers for hashmap keysLennart Poettering
2015-01-09logind: when a bus call is done on a session, user or seat, optionally ↵Lennart Poettering
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!).
2014-12-29machined: ignore spurious errorLennart Poettering
2014-12-28tmpfiles: add new line type 'v' for creating btrfs subvolumesLennart Poettering
2014-12-25logind: remove spurious include of <sys/capability.h>Filipe Brandenburger
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.

2014-12-10sd-bus: move common errors src/shared/bus-errors.h → ↵Lennart Poettering
src/libsystemd/sd-bus/bus-common-errors.h Stuff in src/shared/ should not use stuff from src/libsystemd/ really.
2014-11-28treewide: use log_*_errno whenever %m is in the format stringMichal Schmidt
If the format string contains %m, clearly errno must have a meaningful value, so we might as well use log_*_errno to have ERRNO= logged. Using: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/' Plus some whitespace, linewrap, and indent adjustments.
2014-11-28log: fix order of log_unit_struct() to match other logging callsLennart Poettering
Also, while we are at it, introduce some syntactic sugar for creating ERRNO= and MESSAGE= structured logging fields.

2014-08-18bus-util: simplify bus_verify_polkit_async() a bitLennart Poettering
First, let's drop the "bus" argument, we can determine it from the message anyway. Secondly, determine the right callback/userdata pair automatically from what is currently is being dispatched. This should simplify things a lot for us, since it makes it unnecessary to pass pointers through the original handlers through all functions when we process messages, which might require authentication.
2014-08-15sd-bus: add API to check if a client has privilegesLennart Poettering
This is a generalization of the vtable privilege check we already have, but exported, and hence useful when preparing for a polkit change. This will deal with the complexity that on dbus1 one cannot trust the capability field we retrieve via the bus, since it is read via /proc/$$/stat (and thus might be out-of-date) rather than directly from the message (like on kdbus) or bus connection (as for uid creds on dbus1). Also, port over all code to this new API.

CLOCK_BOOTTIME_ALARM, too
2014-03-11logind: move lid switch handling from logind-main to logind-coreKay Sievers

2014-03-11logind: add a debug message in case the session already existsDjalal Harouni
If the session already exists then the only way to log it is to set the debug option of pam_systemd. There are no debug messages in the login service that permits to log if the session already exists. So just add it, and while we are it add the "uid" field to the debug message that indicates that the session was created.

2014-03-03logind: ignore lid switch events for 30s after each suspend and 3min after ↵Lennart Poettering
startup This is needed to give USB docking stations and suchlike time to settle, so that a display connected to an USB docking station can actually act as a lid swith inhibitor correctly. With this change we should have somewhat reliable docking station support in place.
2014-02-20api: in constructor function calls, always put the returned object pointer ↵Lennart Poettering
first (or second) Previously the returned object of constructor functions where sometimes returned as last, sometimes as first and sometimes as second parameter. Let's clean this up a bit. Here are the new rules: 1. The object the new object is derived from is put first, if there is any 2. The object we are creating will be returned in the next arguments 3. This is followed by any additional arguments Rationale: For functions that operate on an object we always put that object first. Constructors should probably not be too different in this regard. Also, if the additional parameters might want to use varargs which suggests to put them last. Note that this new scheme only applies to constructor functions, not to all other functions. We do give a lot of freedom for those. Note that this commit only changes the order of the new functions we added, for old ones we accept the wrong order and leave it like that.
2014-02-11logind: ignore PropertiesChanged signals for jobsZbigniew Jędrzejewski-Szmek

KillUserProcesses=yes/no should be ignored when termination is explicitly requested.
