2013-10-11event: implement quit handlersLennart Poettering
Quit handlers are executed when an event loop is terminated via sd_event_request_quit(). They are in a way atexit() handlers that are executed in a well-defined environment, time and thread: from the event loop thread when the event loop finishes.
2013-10-11macro: add new assert_return() macro for early parameter checking in functionsLennart Poettering
For the library functions we expose we currently repeatedly use checks like the following: if (!value_is_ok(parameter1)) return -EINVAL; if (!value_is_ok(parameter2)) return -EINVAL; And so on. Let's turn this into a macro: assert_return(value_is_ok(parameter1), -EINVAL); assert_return(value_is_ok(paramater2), -EINVAL); This makes our code a bit shorter and simpler, and also allows us to add a _unlikely_() around the check.

fork()
2013-10-10event: add timer accuracy/coalescing logicLennart Poettering
In order to improve energy consumption we should minimize our wake-ups when handling timers. Hence, for each timer take an accuracy value and schedule the actual wake-up time somewhere between the specified time and the specified timer plus the accuracy. The specified time of timer event sources hence becomes the time the handler is called the *earliest*, and the specified time plus the accuracy the time by which it is called the *latest*, leaving the library the freedom to schedule the wake-up somewhere inbetween. If the accuracy is specified as 0 the default of 250ms will be used. When scheduling timeouts we will now try to elapse them at the same point within each second, across the entire system. We do this by using a fixed perturbation value keyed off the boot id. If this point within a second is not in the acceptable range, we try again with a fixed time within each 250ms time step. If that doesn't work either, we wake up at the last possible time.

2013-10-10bus: fix duplicate comparisonsTero Roponen
Testing for y > x is the same as testing for x < y.
2013-10-10security: rework selinux, smack, ima, apparmor detection logicLennart Poettering
Always cache the results, and bypass low-level security calls when the respective subsystem is not enabled.
2013-10-10login: make sd_session_get_vt() actually workDavid Herrmann
We use VTNR, not VTNr as key. Until now sd_session_get_vt() just returns an error.
2013-10-10login: fix invalid free() in sd_session_get_vt()David Herrmann
We need to clear variables markes as _cleanup_free_. Otherwise, our error-paths might corrupt random memory.
2013-10-10bus: add minimal event loop APILennart Poettering
So far we tried to use epoll directly wherever we needed an event loop. However, that has various shortcomings, such as the inability to handle larger amounts of timers (since each timerfd costs one fd, which is a very limited resource, usually bounded to 1024), and inability to do priorisation between multiple queued events. Let's add a minimal event loop API around epoll that is suitable for implementation of our own daemons and maybe one day can become public API for those who desire it. This loop is part of libsystemd-bus, but may be used independently of it.
2013-10-09journald: remove rotated file from hashmap when rotation failsZbigniew Jędrzejewski-Szmek
Before, when the user journal file was rotated, journal_file_rotate could close the old file and fail to open the new file. In that case, we would leave the old (deallocated) file in the hashmap. On subsequent accesses, we could retrieve this stale entry, leading to a segfault. When journal_file_rotate fails with the file pointer set to 0, old file is certainly gone, and cannot be used anymore. https://bugzilla.redhat.com/show_bug.cgi?id=890463

2013-10-09Smack: Test if smack is enabled before mountingAuke Kok
Since on most systems with xattr systemd will compile with Smack support enabled, we still attempt to mount various fs's with Smack-only options. Before mounting any of these Smack-related filesystems with Smack specific mount options, check if Smack is functionally active on the running kernel. If Smack is really enabled in the kernel, all these Smack mounts are now *fatal*, as they should be. We no longer mount smackfs if systemd was compiled without Smack support. This makes it easier to make smackfs mount failures a critical error when Smack is enabled. We no longer mount these filesystems with their Smack specific options inside containers. There these filesystems will be mounted with there non-mount smack options for now.

2013-10-09keymap: Fix Samsung 900X[34]CMartin Pitt
It appears that it's not really the 900 vs. 940 or the X3 vs X4, but the A/B/C/D suffix after that which makes the difference between the keymaps. On a NP900X3C-A04RU you get MODALIAS=dmi:bvn*:bvr*:bd*:svnSAMSUNGELECTRONICSCO.,LTD.:pn900X3C/900X3D/900X4C/900X4D:* So change the matches to use AB vs. CDG as the differentiator. Thanks to Anatoly Markov for reporting and testing!

2013-10-09libsystemd-bus: add lightweight object vtable implementation for exposing ↵Lennart Poettering
objects on the bus This adds a lightweight scheme how to define interfaces in static fixed arrays which then can be easily registered on a bus connection. This makes it much easier to write bus services. This automatically handles implementation of the Properties, ObjectManager, and Introspection bus interfaces.
2013-10-09core: unify the way we denote serialization attributesLennart Poettering
2013-10-07systemd: serialize/deserialize forbid_restart valueSylvia Else
The Service type's forbid_restart field was not preserved by serialization/deserialization, so the fact that the service should not be restarted after stopping was lost. If a systemctl stop foo command has been given, but the foo service has not yet stopped, and then the systemctl --system daemon-reload was given, then when the foo service eventually stopped, systemd would restart it. https://bugs.freedesktop.org/show_bug.cgi?id=69800
2013-10-07journalctl: flip to --full by defaultZbigniew Jędrzejewski-Szmek
We already shew lines in full when using a pager or not on a tty. The commit disables ellipsization in the sole remaining case, namely when --follow is used. This has been a popular request for a long time, and indeed, full output seems much more useful. Old behaviour can still be requested by using --no-full. Old options retain their behaviour for compatiblity, but aren't advertised as much. This change applies only to jornalctl, not to systemctl, when ellipsization is useful to keep the layout. https://bugzilla.redhat.com/show_bug.cgi?id=984758
2013-10-08udev: support custom Linux Security Module labels for device nodesKay Sievers
2013-10-07Run with a custom SMACK domain (label).Auke Kok
Allows the systemd --system process to change its current SMACK label to a predefined custom label (usually "system") at boot time. This is needed to have a few system-generated folders and sockets automatically be created with the right SMACK label. Without that, processes either cannot communicate with systemd or systemd fails to perform some actions.
2013-10-07Mount /run, /dev/shm usable to tasks when using SMACK.Auke Kok
Once systemd itself is running in a security domain for SMACK, it will fail to start countless tasks due to missing privileges for mounted and created directory structures. For /run and shm specifically, we grant all tasks access. These 2 mounts are allowed to fail, which will happen if the system is not running a SMACK enabled kernel or security=none is passed to the kernel.

Triggered false negatives when encoding a string which needed every character to be escaped, e.g. "LABEL=/".

2013-10-05core: do not add "what" to RequiresMountsFor for network mountsZbigniew Jędrzejewski-Szmek
For cifs mount like //server/share, we would get RequiresMountsFor=/server/share, which probably isn't harmful, but quite confusing. Unfortunately a bunch of static functions had to be moved up, but patch is really one line.
2013-10-04mount: check for NULL before reading pm->whatDave Reisner
Since a57f7e2c828b85, a mount unit with garbage in it would cause systemd to crash on loading it. ref: https://bugs.freedesktop.org/show_bug.cgi?id=70148

2013-10-03systemd: order remote mounts from mountinfo before remote-fs.targetZbigniew Jędrzejewski-Szmek
Usually the network is stopped before filesystems are umounted. Ordering network filesystems before remote-fs.target means that their unmounting will be performed earlier, and can terminate sucessfully. https://bugs.freedesktop.org/show_bug.cgi?id=70002

2013-10-02tmpfiles.d: include setgid perms for /run/log/journalDave Reisner

2013-10-02nspawn: always copy /etc/resolv.conf rather than bind mountLennart Poettering
We were already creating the file if it was missing, and this way containers can reconfigure the file without running into problems. This also makes resolv.conf handling more alike to handling of /etc/localtime, which is also not a bind mount.
