2014-02-11logind: ignore PropertiesChanged signals for jobsZbigniew Jędrzejewski-Szmek
Otherwise we get a (harmless) message like: systemd-logind[30845]: Failed to process message [type=signal sender=:1.36 path=/org/freedesktop/systemd1/job/4674 interface=org.freedesktop.DBus.Properties member=PropertiesChanged signature=sa{sv}as]: Invalid argument
2014-02-11logind: always kill session when termination is requestedZbigniew Jędrzejewski-Szmek
KillUserProcesses=yes/no should be ignored when termination is explicitly requested.
2014-02-11logind: use session_get_state() to get sessions state of the userDjalal Harouni
In function user_get_state() remove the session_is_active() check, just count on the session_get_state() function to get the correct session state. session_is_active() may return true before starting the session scope and user service, this means it will return true even before the creation of the session fifo_fd which will produce incorrect states. So be consistent and just use session_get_state().

systemd-user-sessions.service This way at shutdown we can be sure that the sessions go away before the network.
2014-02-07logind: add function session_jobs_reply() to unify the create replyDjalal Harouni
The session_send_create_reply() function which notifies clients about session creation is used for both session and user units. Unify the shared code in a new function session_jobs_reply(). The session_save() will be called unconditionally on sessions since it does not make sense to only call it if '!session->started', this will also allow to update the session state as soon as possible.
2014-02-07logind: given that we can now relatively safely shutdown sessions copesLennart Poettering
without working cgroup empty notifications there's no need to set the stop timeout of sessions scopes low
2014-02-07logind: rework session shutdown logicLennart Poettering
Simplify the shutdown logic a bit: - Keep the session FIFO around in the PAM module, even after the session shutdown hook has been finished. This allows logind to track precisely when the PAM handler goes away. - In the ReleaseSession() call start a timer, that will stop terminate the session when elapsed. - Never fiddle with the KillMode of scopes to configure whether user processes should be killed or not. Instead, simply leave the scope units around when we terminate a session whose processes should not be killed. - When killing is enabled, stop the session scope on FIFO EOF or after the ReleaseSession() timeout. When killing is disabled, simply tell PID 1 to abandon the scope. Because the scopes stay around and hence all processes are always member of a scope, the system shutdown logic should be more robust, as the scopes can be shutdown as part of the usual shutdown logic.
2014-02-05Update some message formatsZbigniew Jędrzejewski-Szmek
Use PID_FMT/USEC_FMT/... in more places. Also update logind error messages to print the full path to a file that failed. This should make debugging easier for people who do not know off the top of their head where logind stores it state.
2014-02-05man: introduce new "Desktop" property for sessionsLennart Poettering
This is initialized from XDG_SESSION_DESKTOP and is useful for GNOME to recognize its own sessions. It's supposed to be set to a short string identifying the session, such as "kde" or "gnome".
2014-02-05logind: make session type and class settable via the same waysLennart Poettering
If the session type/class is set via environment variables, use that, and otherwise fallback to something that is set via the PAM module command line.

2014-01-26pam_systemd: Ignore vtnr when seat != seat0Matthew Monaco
logind considers it an error for a seat other than seat0 to have a non-zero vtnr for CreateSession
2014-01-25build-sys: create "compatibility libraries" sectionZbigniew Jędrzejewski-Szmek
Compat stuff is moved to src/compat-libs/. Warnings are issued when programs are linked with the deprecated library.
2014-01-25build-sys: merge libsystemd-login into libsystemdZbigniew Jędrzejewski-Szmek
A compatibility libsystemd-login library is created which uses .symver and ifunc magic proposed by Lennart to make programs linked to the old library name continue to work seamlessly. Unfortunately the bfd linker crashes: https://sourceware.org/bugzilla/show_bug.cgi?id=16467 This will be fixed in binutils 2.25. As a work-around, gold can be used: LDFLAGS=-Wl,-fuse-ld=gold Unfortunately the switch to pick the linker appeared in gcc 4.8. This also doesn't work with LLVM: http://llvm.org/bugs/show_bug.cgi?id=11897
2014-01-20logind: introduce session "positions"David Herrmann
logind has no concept of session ordering. Sessions have a unique name, some attributes about the capabilities and that's already it. There is currently no stable+total order on sessions. If we use the logind API to switch between sessions, we are faced with an unordered list of sessions we have no clue of. This used to be no problem on seats with VTs or on seats with only a single active session. However, with the introduction of multi-session capability for seats without VTs, we need to find a way to order sessions in a stable way. This patch introduces session "positions". A position is a simple integer assigned to a session which is never changed implicitly (currently, we also don't change it explicitly, but that may be changed someday). For seats with VTs, we force the position to be the same as the VTnr. Without VTs, we simply find the lowest unassigned number and use it as position. If position-assignment fails or if, for any reason, we decide to not assign a position to a session, the position is set to 0 (which is treated as invalid position). During session_load() or if two sessions have the same VTnr, we may end up with two sessions with the same position (this shouldn't happen, but lets be fail-safe in case some other part of the stack fails). This case is dealt with gracefully by ignoring any session but the first session assigned to the position. Thus, session->pos is a hint, seat->positions[i] is the definite position-assignment. Always verify both match in case you need to modify them! Additionally, we introduce SwitchTo(unsigned int) on the seat-dbus-API. You can call it with any integer value != 0 and logind will try to switch to the request position. If you implement a compositor or any other session-controller, you simply watch for ctrl+alt+F1 to F12 and call SwitchTo(Fx). logind will figure a way out deal with this number. For convenience, we also introduce SwitchToNext/Previous(). It should be called on ctrl+alt+Left/Right (like the kernel-console used to support). Note that the public API (SwitchTo*()) is *not* bound to the underlying logic that is implemented now. We don't export "session-positions" on the dbus/C API! They are an implementation detail. Instead, the SwitchTo*() API is supposed to be a hint to let logind choose the session-switching logic. Any foreground session-controller is free to enumerate/order existing sessions according to their needs and call Session.Activate() manually. But the SwitchTo*() API provides a uniform behavior across session-controllers. Background: Session-switching keys depend on the active keymap. The XKB specification provides the XKB_KEY_XF86Switch_VT_1-12 key-symbols which have to be mapped by all keymaps to allow session-switching. It is usually bound to ctrl+alt+Fx but may be set differently. A compositor passes any keyboard input to XKB before passing it to clients. In case a key-press invokes the XKB_KEY_XF86Switch_VT_x action, the keypress is *not* forwarded to clients, but instead a session-switch is scheduled. This actually prevents us from handling these keys outside of the session. If an active compositor has a keymap with a different mapping of these keys, and logind itself tries to catch these combinations, we end up with the key-press sent to the compositor's clients *and* handled by logind. This is *bad* and we must avoid this. The only situation where a background process is allowed to handle key-presses is debugging and emergency-keys. In these cases, we don't care for keymap mismatches and accept the double-event. Another exception is unmapped keys like PowerOff/Suspend (even though this one is controversial).
2014-01-15logind: get rid of X11 display socket symlinkLennart Poettering
X11 never made use of it anyway and it's probably better to just push $DISPLAY into the systemd daemon from gnome-session (or equivalent program) than to change libX11 to look for this socket. In particular since we won't need this for Wayland anyway and we shouldn't add infrastructure for stuff that's on its way out anyway.

This reverts commit 9130f2128b64de19a3b7d6db7e0d371adfd296c2. It's too early to do that. For now we should only "break" the --enable-kdbus case, not the normal one.

2013-12-21loginctl: correctly show session IDs on session-statusDjalal Harouni
Commit f8f14b3654bcd introduced a regression that makes loginctl session-status to not show the correct session ID(s) In print_session_status_info() the map[] array, element "Seat" receives the offset of the "id" in "SessionStatusInfo" struct instead of the offset of the "seat" member. This will cause prop_map_first_of_struct() function to overwrite the SessionStatusInfo.id memory with seats if there are any. Fix this typo by using the "seat" member.

2013-12-18loginctl: improve print_{session|user|seat}_status_info() functionsDjalal Harouni
1) Instead of checking if we need to print a new line on each iteration, pass the "new_line" as a pointer to those functions, so they can use it to check if a new line is needed. This makes the code more consistent as it is done in other places: machinectl, systemctl... 2) Move the error messages from show_{session|user|seat}() to their appropriate print_{session|user|seat}_status_info() functions, this will prevent from logging an error message twice in case show_properties() fails and it will improve code readability. 3) Also do not ignore error codes on these functions.
