2015-09-08nspawn: properly propagate errors when we fail to set soemthing upLennart Poettering
2015-09-07nspawn: sort and clean up included header listLennart Poettering
Let's remove unnecessary inclusions, and order the list alphabetically as suggested in CODING_STYLE now.

2015-09-07nspawn: split out mount related functions into a new nspawn-mount.c fileLennart Poettering
2015-09-07unit: move "not supported" check after condition check in unit_start()Lennart Poettering
Make sure we always check conditions before checking whether the unit type is supported in unit_start(), since condition checks are "clean errors", while "not supported" errors are fatal. This cleans up the boot output of systemd in containers, where a lot of NOTSUPP lines were shown befor this fix. This partially reverts 8ff4d2ab0d4758e914aea6d86154d85f2b2c787f which reorder the checks.

2015-09-07tests: Skip test-cgroup-util test_mask_supported() when not running under ↵Martin Pitt
systemd Commit 5f4c5fef6 introduced this new test case, but this does not work in build chroots where cgroupfs is not mounted. So skip the test if systemd is not running.

various fixes to the core, logind, machined, nspawn
2015-09-07sd-event: make sure to create a signal queue for the right signalLennart Poettering
We should never access the "signal" part of the event source unless the event source is actually for a signal. In this case it's a child pid handler however, hence make sure to use the right signal. This is a fix for PR #1177, which in turn was a fix for 9da4cb2be260ed123f2676cb85cb350c527b1492.

2015-09-07gpt-auto: minor simplificatin handling the no-auto GPT flagLennart Poettering
Let's query the flags only once, and document why we ignore it for the ESP.
2015-09-07gpt-auto: try to handle LUKS root partitions betterLennart Poettering
If the root file system is located on an encrypted root disk, we'll not find the GPT partition table for it. Let's fix that by following the slaves/ symlinks in /sys for the device. We only handle devices having exactly one backing device. Also see: #1167

sd-bus: make introspection data non-recursive
2015-09-06nspawn: add new .nspawn files for container settingsLennart Poettering
.nspawn fiels are simple settings files that may accompany container images and directories and contain settings otherwise passed on the nspawn command line. This provides an efficient way to attach execution data directly to containers.
2015-09-05machine: make sure to call unlockpt() even for local host pty connectionsLennart Poettering
This fixes breakage for local host pty handling, introduced in 395745ba533ac91fe118f43ec83f13a752c0b473. Fixes #1139
2015-09-05logind: make scope of wall message handling smallerLennart Poettering
2015-09-05unit: make unit_can_start() more accurateLennart Poettering
This funciton is exposed via CanStart on the bus, and should be as accurate as possible. Hence: make sure to return false for units of unit types not supported on the system, and for unit types where configuration failed to load. Also see #1105.

2015-09-05sd-bus: make introspection data non-recursiveDavid Herrmann
Currently, our introspection data looks like this: <node> <interface name="org.freedesktop.DBus.Peer"> ... </interface> <interface name="org.freedesktop.DBus.Introspectable"> ... </interface> <interface name="org.freedesktop.DBus.Properties"> ... </interface> <node name="org"/> <node name="org/freedesktop"/> <node name="org/freedesktop/login1"/> <node name="org/freedesktop/login1/user"/> <node name="org/freedesktop/login1/user/self"/> <node name="org/freedesktop/login1/user/_1000"/> <node name="org/freedesktop/login1/seat"/> <node name="org/freedesktop/login1/seat/self"/> <node name="org/freedesktop/login1/seat/seat0"/> <node name="org/freedesktop/login1/session"/> <node name="org/freedesktop/login1/session/self"/> <node name="org/freedesktop/login1/session/c1"/> </node> (ordered alphabetically for better visibility) This is grossly incorrect. The spec says that we're allowed to return non-directed children, however, it does not allow us to return data recursively in multiple parents. If we return "org", then we must not return anything else that starts with "org/". It is unclear, whether we can include child-nodes as a tree. Moreover, it is usually not what the caller wants. Hence, this patch changes sd-bus to never return introspection data recursively. Instead, only a single child-layer is returned. This patch relies on enumerators to never return hierarchies. If someone registers an enumerator via sd_bus_add_enumerator, they better register sub-enumerators if they support *TRUE* hierarchies. Each enumerator is treated as a single layer and not filtered. Enumerators are still allowed to return nested data. However, that data is still required to be a single hierarchy. For instance, returning "/org/foo" and "/com/bar" is fine, but including "/com" or "/org" in that dataset is not. This should be the default for enumerators and I see no reason to filter in sd-bus. Moreover, filtering that data-set would require to sort the strv by path and then do prefix-filtering. This is O(n log n), which would be fine, but still better to avoid. Fixes #664.
2015-09-05sd-bus: derive uid from cgroup if possibleDavid Herrmann
Whenever we run in a user context, sd_bus_{default_user,open_user}() and friends should always connect to the user-bus of the current context, instead of deriving the uid from getuid(). This allows us running programs via sudo/su, without the nasty side-effect of accidentally connecting to the root user-bus. This patch enforces the idea of making su/sudo *not* opening sessions by default. That is, all they do is raising privileges, but keeping everything set as before. You can still use su/sudo to open real sessions by requesting a login-session (or loading pam_systemd otherwise). However, in this case XDG_RUNTIME_DIR= will not be set (as usual in these cases), hence, you will not be able to connect to *any* user-bus. Long story short: With this patch applied, both: - ./busctl --user - sudo ./busctl --user ..will successfully connect to the user-bus of the local user. Fixes #390.
2015-09-06core: pass details to polkit for some unit actionsMichael Chapman
The following details are passed: - unit: the primary name of the unit upon which the action was invoked (i.e. after resolving any aliases); - verb: one of 'start', 'stop', 'reload', 'restart', 'try-restart', 'reload-or-restart', 'reload-or-try-restart', 'kill', 'reset-failed', or 'set-property', corresponding to the systemctl verb used to invoke the action. Typical use of these details in a polkit policy rule might be: // Allow alice to manage example.service; // fall back to implicit authorization otherwise. polkit.addRule(function(action, subject) { if (action.id == "org.freedesktop.systemd1.manage-units" && action.lookup("unit") == "example.service" && subject.user == "alice") { return polkit.Result.YES; } }); We also supply a custom polkit message that includes the unit's name and the requested operation.
2015-09-06bus-util: support details in CheckAuthorization callsMichael Chapman
Extra details for an action can be supplied when calling polkit's CheckAuthorization method. Details are a list of key/value string pairs. Custom policy can use these details when making authorization decisions.

2015-09-05sd-login: add new sd_pid_get_cgroup() APILennart Poettering
This adds a new sd_pid_get_cgroup() call to sd-login which may be used to query the control path of a process. This is useful for programs when making use of delegation units, in order to figure out which subtree has been delegated. In light of the unified control group hierarchy this is finally safe to do, hence let's add a proper API for it, to make it easier to use this.

2015-09-04networkd: adjust error codes for nonexisting DHCP dataMartin Pitt
Commit 0339cd770 changed libsystemd-network's error code for missing DHCP lease data from ENOENT to ENODATA. Adjust networkd accordingly. This fixes interfaces being stuck in "degraded/configuring" mode forever. https://github.com/systemd/systemd/issues/1147
2015-09-04tests: Skip tests which need to access /sys/fs/cgroup if that is not availableMartin Pitt
Commit efdb023 ("core: unified cgroup hierarchy support") introduced a new error ENOEXEC in cg_unified() if /sys/fs/cgroup/ is not available. Adjust the "skip" checks in various tests accordingly. Add a corresponding "skip" check to test-bus-creds as well, as sd_bus_creds_new_from_pid() now calls cg_unified() as well. This re-fixes "make check" in build chroots without /sys/fs/cgroup. https://github.com/systemd/systemd/issues/1132

2015-09-04cgroups: delegation to unprivileged services is safe in the unified hierarchyLennart Poettering
Delegation to unpriviliged processes is safe in the unified hierarchy, hence allow it. This has the benefit of permitting "systemd --user" instances to further partition their resources between user services.
2015-09-04sd-login: rework error handlingLennart Poettering
Makre sure we always return sensible errors for the various, following the same rules, and document them in a comment in sd-login.c. Also, update all relevant man pages accordingly.
2015-09-04sd-event: make sure RT signals are not droppedLennart Poettering
RT signals operate in a queue, and we should be careful to never merge two queued signals into one. Hence, makes sure we only ever dequeue a single signal at a time and leave the remaining ones queued in the signalfd. In order to implement correct priorities for the signals introduce one signalfd per priority, so that we only process the highest priority signal at a time.

2015-09-04nspawn: enable all controllers we can for the "payload" subcgroup we createLennart Poettering
In the unified hierarchy delegating controller access is safe, hence make sure to enable all controllers for the "payload" subcgroup if we create it, so that the container will have all controllers enabled the nspawn service itself has.
