2013-09-26core: rework how we match mount units against each otherLennart Poettering
Previously to automatically create dependencies between mount units we matched every mount unit agains all others resulting in O(n^2) complexity. On setups with large amounts of mount units this might make things slow. This change replaces the matching code to use a hashtable that is keyed by a path prefix, and points to a set of units that require that path to be around. When a new mount unit is installed it is hence sufficient to simply look up this set of units via its own file system paths to know which units to order after itself. This patch also changes all unit types to only create automatic mount dependencies via the RequiresMountsFor= logic, and this is exposed to the outside to make things more transparent. With this change we still have some O(n) complexities in place when handling mounts, but that's currently unavoidable due to kernel APIs, and still substantially better than O(n^2) as before. https://bugs.freedesktop.org/show_bug.cgi?id=69740

2013-09-26Move part of logind.c into a separate fileZbigniew Jędrzejewski-Szmek
liblogind-core.la was underlinked, missing a few functions defined in logind.c. They are moved to a new file, logind-core.c, and this file is linked into liblogind-core.la. In addition, logind-acl.c is attached to the liblogind-core.la, instead of systemd-logind directly.

2013-09-26build-sys: add ./configure --enable-address-sanitizerZbigniew Jędrzejewski-Szmek
Enabling address sanitizer seems like a useful thing, but is quite tricky. Proper flags have to be passed to CPPFLAGS, CFLAGS and LDFLAGS, but passing them on the commandline doesn't work because we tests are done with ld directly, and not with libtool like in real linking. We might want to fix this, but let's add a handy way to enable address checking anyway.

2013-09-25cgroup: if we do a cgroup operation then do something on all supported ↵Lennart Poettering
controllers Previously we did operations like attach, trim or migrate only on the controllers that were enabled for a specific unit. With this changes we will now do them for all supproted controllers, and fall back to all possible prefix paths if the specified paths do not exist. This fixes issues if a controller is being disabled for a unit where it was previously enabled, and makes sure that all processes stay as "far down" the tree as groups exist.

2013-09-19build-sys: don't build python modules after --without-pythonZbigniew Jędrzejewski-Szmek
The modules should build just fine, but AM_PATH_PYTHON sets pkgpyexecdir for us. Without that variable we don't know where to install modules. In addition libtool tries an empty rpath, breaking the build. Those issues could be fixed or worked around, but we probably don't have many people who want to avoid using python binary, but want to compile python modules. If such uses ever come up, this issue should be revisited.

2013-09-19nspawn: be less liberal about creating bind mount destinationsDave Reisner
Previously, if a file's bind mount destination didn't exist, nspawn would blindly create a directory, and the subsequent bind mount would fail. Examine the filetype of the source and ensure that, if the destination does not exist, that it is created appropriately. Also go one step further and ensure that the filetypes of the source and destination match.

In the process, rename udev_encode_string which is poorly named for what it does. It deals specifically with encoding names that udev creates and has its own rules: utf8 is valid but some ascii is not (e.g. path separators), and everything else is simply escaped. Rename it to encode_devnode_name.

2013-09-17gpt-auto-generator: do not assume that /dev/block/%u:%u is useableLennart Poettering
The generator might run before udev, and udev sets up the /dev/block/ symlinks, hence we cannot use them from the gpt generator. Instead, manually translate a major/minor to a device node.

2013-09-17logind: implement generic multi-sessionDavid Herrmann
This enables the multi-session capability for seats that don't have VTs. For legacy seats with VTs, everything stays the same. However, all other seats now also get the multi-session capability. The only feature that was missing was session-switching. As logind can force a session-switch and signal that via the "Active" property, we only need a way to allow synchronized/delayed session switches. Compositors need to cleanup some devices before acknowledging the session switch. Therefore, we use the session-devices to give compositors a chance to block a session-switch until they cleaned everything up. If you activate a session on a seat without VTs, we send a PauseDevice signal to the active session for every active device. Only once the session acknowledged all these with a PauseDeviceComplete() call, we perform the final session switch. One important note is that delayed session-switching is meant for backwards compatibility. New compositors or other sessions should really try to deal correctly with forced session switches! They only need to handle EACCES/EPERM from syscalls and treat them as "PauseDevice" signal. Following logind patches will add a timeout to session-switches which forces the switch if the active session does not react in a timely fashion. Moreover, explicit ForceActivate() calls might also be supported. Hence, sessions must not crash if their devices get paused.
2013-09-17logind: introduce session-devicesDavid Herrmann
A session-device is a device that is bound to a seat and used by a session-controller to run the session. This currently includes DRM, fbdev and evdev devices. A session-device can be created via RequestDevice() on the dbus API of the session. You can drop it via ReleaseDevice() again. Once the session is destroyed or you drop control of the session, all session-devices are automatically destroyed. Session devices follow the session "active" state. A device can be active/running or inactive/paused. Whenever a session is not the active session, no session-device of it can be active. That is, if a session is not in foreground, all session-devices are paused. Whenever a session becomes active, all devices are resumed/activated by logind. If it fails, a device may stay paused. With every session-device you request, you also get a file-descriptor back. logind keeps a copy of this fd and uses kernel specific calls to pause/resume the file-descriptors. For example, a DRM fd is muted by logind as long as a given session is not active. Hence, the fd of the application is also muted. Once the session gets active, logind unmutes the fd and the application will get DRM access again. This, however, requires kernel support. DRM devices provide DRM-Master for synchronization, evdev devices have EVIOCREVOKE (pending on linux-input-ML). fbdev devices do not provide such synchronization methods (and never will). Note that for evdev devices, we call EVIOCREVOKE once a session gets inactive. However, this cannot be undone (the fd is still valid but mostly unusable). So we reopen a new fd once the session is activated and send it together with the ResumeDevice() signal. With this infrastructure in place, compositors can now run without CAP_SYS_ADMIN (that is, without being root). They use RequestControl() to acquire a session and listen for devices via udev_monitor. For every device they want to open, they call RequestDevice() on logind. This returns a fd which they can use now. They no longer have to open the devices themselves or call any privileged ioctls. This is all done by logind. Session-switches are still bound to VTs. Hence, compositors will get notified via the usual VT mechanisms and can cleanup their state. Once the VT switch is acknowledged as usual, logind will get notified via sysfs and pause the old-session's devices and resume the devices of the new session. To allow using this infrastructure with systems without VTs, we provide notification signals. logind sends PauseDevice("force") dbus signals to the current session controller for every device that it pauses. And it sends ResumeDevice signals for every device that it resumes. For seats with VTs this is sent _after_ the VT switch is acknowledged. Because the compositor already acknowledged that it cleaned-up all devices. However, for seats without VTs, this is used to notify the active compositor that the session is about to be deactivated. That is, logind sends PauseDevice("force") for each active device and then performs the session-switch. The session-switch changes the "Active" property of the session which can be monitored by the compositor. The new session is activated and the ResumeDevice events are sent. For seats without VTs, this is a forced session-switch. As this is not backwards-compatible (xserver actually crashes, weston drops the related devices, ..) we also provide an acknowledged session-switch. Note that this is never used for sessions with VTs. You use the acknowledged VT-switch on these seats. An acknowledged session switch sends PauseDevice("pause") instead of PauseDevice("force") to the active session. It schedules a short timeout and waits for the session to acknowledge each of them with PauseDeviceComplete(). Once all are acknowledged, or the session ran out of time, a PauseDevice("force") is sent for all remaining active devices and the session switch is performed. Note that this is only partially implemented, yet, as we don't allow multi-session without VTs, yet. A follow up commit will hook it up and implemented the acknowledgements+timeout. The implementation is quite simple. We use major/minor exclusively to identify devices on the bus. On RequestDevice() we retrieve the udev_device from the major/minor and search for an existing "Device" object. If no exists, we create it. This guarantees us that we are notified whenever the device changes seats or is removed. We create a new SessionDevice object and link it to the related Session and Device. Session->devices is a hashtable to lookup SessionDevice objects via major/minor. Device->session_devices is a linked list so we can release all linked session-devices once a device vanishes. Now we only have to hook this up in seat_set_active() so we correctly change device states during session-switches. As mentioned earlier, these are forced state-changes as VTs are currently used exclusively for multi-session implementations. Everything else are hooks to release all session-devices once the controller changes or a session is closed or removed.

2013-09-17journald: avoid NSS in journaldLennart Poettering
In order to avoid a deadlock between journald looking up the "systemd-journal" group name, and nscd (or anyother NSS backing daemon) logging something back to the journal avoid all NSS in journald the same way as we avoid it from PID 1. With this change we rely on the kernel file system logic to adjust the group of created journal files via the SETGID bit on the journal directory. To ensure that it is always set, even after the user created it with a simply "mkdir" on the shell we fix it up via tmpfiles on boot.
