2014-08-14logind: add new session type "web" for PAM web clients, such as cockpitLennart Poettering
On request of Stef Walter.
2014-08-13login: share VT-signal handler between sessionsDavid Herrmann
sd-event does not allow multiple handlers for a single signal. However, logind sets up signal handlers for each session with VT_PROCESS set (that is, it has an active controller). Therefore, registering multiple such controllers will fail. Lets make the VT-handler global, as it's mostly trivial, anyway. This way, the sessions don't have to take care of that and we can simply acknowledge all VT-switch requests as we always did.
2014-08-11login: set_controller should fail if prepare_vt failsOlivier Brunel
If controllers can expect logind to have "prepared" the VT (e.g. set it to graphics mode, etc) then TakeControl() should fail if said preparation failed (and session_restore_vt() was called). (David: fixed up !CONFIG_VT case and errno-numbers)
2014-08-04bus: always explicitly close bus from main programsLennart Poettering
Since b5eca3a2059f9399d1dc52cbcf9698674c4b1cf0 we don't attempt to GC busses anymore when unsent messages remain that keep their reference, when they otherwise are not referenced anymore. This means that if we explicitly want connections to go away, we need to close them. With this change we will no do so explicitly wherver we connect to the bus from a main program (and thus know when the bus connection should go away), or when we create a private bus connection, that really should go away after our use. This fixes connection leaks in the NSS and PAM modules.
2014-08-03Unify parse_argv styleZbigniew Jędrzejewski-Szmek
getopt is usually good at printing out a nice error message when commandline options are invalid. It distinguishes between an unknown option and a known option with a missing arg. It is better to let it do its job and not use opterr=0 unless we actually want to suppress messages. So remove opterr=0 in the few places where it wasn't really useful. When an error in options is encountered, we should not print a lengthy help() and overwhelm the user, when we know precisely what is wrong with the commandline. In addition, since help() prints to stdout, it should not be used except when requested with -h or --help. Also, simplify things here and there.
2014-07-31Reject invalid quoted stringsZbigniew Jędrzejewski-Szmek
String which ended in an unfinished quote were accepted, potentially with bad memory accesses. Reject anything which ends in a unfished quote, or contains non-whitespace characters right after the closing quote. _FOREACH_WORD now returns the invalid character in *state. But this return value is not checked anywhere yet. Also, make 'word' and 'state' variables const pointers, and rename 'w' to 'word' in various places. Things are easier to read if the same name is used consistently. mbiebl_> am I correct that something like this doesn't work mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"' mbiebl_> systemd seems to strip of the quotes mbiebl_> systemctl status shows mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint mbiebl_> which is pretty weird

2014-07-18Be more verbose when bind or listen failsZbigniew Jędrzejewski-Szmek
Also be more verbose in devnode_acl_all().
2014-07-16Let config_parse open file where applicableZbigniew Jędrzejewski-Szmek
Special care is needed so that we get an error message if the file failed to parse, but not when it is missing. To avoid duplicating the same error check in every caller, add an additional 'warn' boolean to tell config_parse whether a message should be issued. This makes things both shorter and more robust wrt. to error reporting.

2014-07-15rules: consistently use "?*" instead of "*?"Kay Sievers
2014-07-08logind: allow switching to unused VTs via SwitchTo()David Herrmann
If compositors use the new SwitchTo() logic to map F1-F12, we should allow them to switch to unregistered VTs, too. Otherwise, the auto-spawn logic of gettys won't trigger. Reported-by: Jasper St. Pierre <jstpierre@mecheye.net> Signed-off-by: David Herrmann <dh.herrmann@gmail.com>

2014-05-22logind: also escape external data when saving to /runLennart Poettering
Better be safe than sorry...
2014-05-19logind: fix Display property of user objectsLennart Poettering
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.
2014-05-16logind: allow suspending if there are no displaysMantas Mikulėnas
With proprietary graphics drivers, there won't be any 'drm' devices in sysfs, so logind will never suspend the system upon closing the lid, even if only one (internal) display is connected. This has been reported by multiple users so far. IMHO, it's better to suspend the system in this case for safety reasons, to avoid having nvidia blob users' laptops overheat, for the same reason that sleep inhibitors are overridden (LidSwitchIgnoreInhibited=yes).
2014-05-15logind: bring polkit policy for hibernate in line with suspend/poweroff/rebootLennart Poettering
THere's no reason why hibernate should be better protected then suspendor poweroff, so sync the policies.
2014-05-15Remove unnecessary casts in printfsZbigniew Jędrzejewski-Szmek
No functional change expected :)
2014-05-15sd-bus: introduce sd_bus_slot objects encapsulating callbacks or vtables ↵Lennart Poettering
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).
2014-05-13replace more dup() by F_DUPFD_CLOEXECLennart Poettering
2014-05-13pam_systemd: use F_DUPFD_CLOEXEC when dupping session fdsLennart Poettering

2014-04-23use new name DRAW_TREE_VERTICALThomas Hindoe Paaboel Andersen
Was renamed in 6b01f1d3911bd7c7eadbb8a3b4375bd3ac05c98f
2014-04-23login: rename session_mute_vt() to session_prepare_vt()David Herrmann
This function is no longer just about muteing the VT. We do all kinds of VT setup for sessions using the controller-API. Rename the function to something more appropriate.
2014-04-23login: give session ownership of VTRay Strode
The tty associated with a VT should be owned by the owner of the session running on the VT. This is important for supporting a socket activated X server, since the X server will open the tty itself. This commit makes sure to chown the tty any time a session is created and and chown it back to root any time the session is removed. This behavior is copied from /bin/login.
2014-04-12Unify GREEDY_REALLOC and GREEDY_REALLOC_TZbigniew Jędrzejewski-Szmek
greedy_realloc() and greedy_realloc0() now store the allocated size as the count, not bytes. Replace GREEDY_REALLOC uses with GREEDY_REALLOC_T everywhere, and then rename GREEDY_REALLOC_T to GREEDY_REALLOC. It is just too error-prone to have two slightly different macros which do the same thing.
2014-04-09login: add 'mir' to the list of session typesDavid Herrmann
Add Mir to the list of session types. This is implemented for LightDM in lp:~robert-ancell/lightdm/xdg-session-desktop [1]. [1] https://code.launchpad.net/~robert-ancell/lightdm/xdg-session-desktop/+merge/214108 (david: adjusted commit-header and fixed whitespace issues)
2014-04-05logind: remove one castZbigniew Jędrzejewski-Szmek
2014-04-02logind: don't print error if devices vanish during ACL-initDavid Herrmann
If a device is unplugged while we initialize it, we will get ENOENT for ACL-init (and related stuff). We currently print errors then, which is misleading. Print a debug-message early and continue.
2014-03-24sd-event: rework API to support CLOCK_REALTIME_ALARM and ↵Lennart Poettering
CLOCK_BOOTTIME_ALARM, too
2014-03-18util: replace close_nointr_nofail() by a more useful safe_close()Lennart Poettering
safe_close() automatically becomes a NOP when a negative fd is passed, and returns -1 unconditionally. This makes it easy to write lines like this: fd = safe_close(fd); Which will close an fd if it is open, and reset the fd variable correctly. By making use of this new scheme we can drop a > 200 lines of code that was required to test for non-negative fds or to reset the closed fd variable afterwards.
2014-03-17build-sys: move sd-login src/login → src/libsystemd/sd-loginLennart Poettering
After all, it is ultimately linked to libsystems.so anyway, thus belongs there and shares very little with the rest of logind, hence let's move this away.
2014-03-17sd-login: add calls that retrieve credentials of peers connected to AF_UNIX ↵Lennart Poettering
peers This is supposed to be an extension of SO_PEERCRED and SO_PEERSEC, except for cgroup information.
2014-03-14logind: automatically remove SysV + POSIX IPC objects when the users owning ↵Lennart Poettering
them fully log out
2014-03-12sd-login: add sd_machine_get_class() callLennart Poettering
2014-03-11logind: move lid switch handling from logind-main to logind-coreKay Sievers
../src/login/logind-dbus.c:1352: error: undefined reference to 'manager_set_lid_switch_ignore' collect2: error: ld returned 1 exit status make[2]: *** [test-login-tables]
2014-03-11bus: replace sd_bus_label_{escape,unescape}() by new ↵Lennart Poettering
sd_bus_path_{encode,decode}() The new calls work similarly, but enforce a that a common, fixed bus path prefix is used. This follows discussions with Simon McVittie on IRC that it should be a good idea to make sure that people don't use the escaping applied here too wildly as anything other than the last label of a bus path.
2014-03-11logind: Do not fail display count if a device has no parentMantas Mikulėnas
udev_device_get_parent() may return NULL when the device doesn't have a parent, as is the case with (for example) /sys/devices/virtual/drm/ttm. Also, log an actual error message instead of "-12 displays connected".
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.
2014-03-10logind: fix policykit checksZbigniew Jędrzejewski-Szmek
2014-03-07Make tables for DEFINE_STRING_TABLE_LOOKUP consistentDaniel Mack
Bring some arrays that are used for DEFINE_STRING_TABLE_LOOKUP() in the same order than the enums they reference. Also, pass the corresponding _MAX value to the array initalizer where appropriate.
2014-03-06logind: fix reference to systemd-user-sessions.serviceLennart Poettering
2014-03-04logind: make $XDG_RUNTIME_DIR a per-user tmpfsLennart Poettering
This way each user allocates from his own pool, with its own size limit. This puts the size limit by default to 10% of the physical RAM size but makes it configurable in logind.conf.
2014-03-04Introduce strv_consume which takes ownershipZbigniew Jędrzejewski-Szmek
This mirrors set_consume and makes the common use a bit nicer.

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.
