2014-08-27util: make lookup_uid() globalDavid Herrmann
This is a useful helper, make it global. It will be required for libsystemd-terminal, at minimum.
2014-08-27udev: add missing new-line in udevadm errorDavid Herrmann
fprintf() does not add new-lines automatically like log_*() does. Add the missing \n specified so "udevadm" invoked without arguments adds a newline to: udevadm: missing or unknown command
2014-08-27login: fix memory-leak on DropController()David Herrmann
Our bus-name watch helpers only remove a bus-name if it's not a controller, anymore. If we call manager_drop_busname() before unregistering the controller, the busname will not be dropped. Therefore, first drop the controller, then drop the bus-name.
2014-08-27shared: make container_of() use unique variable namesDavid Herrmann
If you stack container_of() macros, you will get warnings due to shadowing variables of the parent context. To avoid this, use unique names for variables. Two new helpers are added: UNIQ: This evaluates to a truly unique value never returned by any evaluation of this macro. It's a shortcut for __COUNTER__. UNIQ_T: Takes two arguments and concatenates them. It is a shortcut for CONCATENATE, but meant to defined typed local variables. As you usually want to use variables that you just defined, you need to reference the same unique value at least two times. However, UNIQ returns a new value on each evaluation, therefore, you have to pass the unique values into the macro like this: #define my_macro(a, b) __max_macro(UNIQ, UNIQ, (a), (b)) #define __my_macro(uniqa, uniqb, a, b) ({ typeof(a) UNIQ_T(A, uniqa) = (a); typeof(b) UNIQ_T(B, uniqb) = (b); MY_UNSAFE_MACRO(UNIQ_T(A, uniqa), UNIQ_T(B, uniqb)); }) This way, MY_UNSAFE_MACRO() can safely evaluate it's arguments multiple times as they are local variables. But you can also stack invocations to the macro my_macro() without clashing names. This is the same as if you did: #define my_macro(a, b) __max_macro(__COUNTER__, __COUNTER__, (a), (b)) #define __my_macro(prefixa, prefixb, a, b) ({ typeof(a) CONCATENATE(A, prefixa) = (a); typeof(b) CONCATENATE(B, prefixb) = (b); MY_UNSAFE_MACRO(CONCATENATE(A, prefixa), CONCATENATE(B, prefixb)); }) ...but in my opinion, the first macro is easier to write and read. This patch starts by converting container_of() to use this new helper. Other macros may follow (like MIN, MAX, CLAMP, ...).
2014-08-27shared: drop UNIQUE()David Herrmann
The UNIQUE() macro works fine if used in un-stacked macros. However, once you stack them like: MAX(MIN(a, b), CLAMP(MAX(c, d), e, f)) you will get warnings due to shadowing other variables. gcc uses the last line of a macro expansion as value for __LINE__, therefore, we cannot even avoid this by splitting the expressions across lines. Remove the only user of UNIQUE() so we introduce a new helper in follow-ups.

2014-08-26man: reword sd-hibernate-resume description and add linkZbigniew Jędrzejewski-Szmek
"each device" was suggesting that this service might be instantiated multiple times. "hibernation resume" was too jargon-y.
2014-08-26hibernate-resume-generator: add a generator for instantiating the resume unit.Ivan Shapovalov
hibernate-resume-generator understands resume= kernel command line parameter and instantiates the systemd-resume@.service accordingly if it is passed. This enables resume from hibernation using device specified on the kernel command line, and it may be specified either as "/dev/disk/by-foo/bar" or "FOO=bar", not only "/dev/sdXY" which is understood by the in-kernel implementation. So now resume= is brought on par with root= in terms of possible ways to specify a device.
2014-08-26hibernate-resume: add a tool to write a device node's major:minor to ↵Ivan Shapovalov
/sys/power/resume. This can be used to initiate a resume from hibernation by path to a swap device containing the hibernation image. The respective templated unit is also added. It is instantiated using path to the desired resume device.
2014-08-26units: order systemd-fsck@.service after local-fs-pre.target.Ivan Shapovalov
With this change, it becomes possible to order a unit to activate before any modifications to the file systems. This is especially useful for supporting resume from hibernation.

2014-08-26util: reset signals when we fork off agentsLennart Poettering
If we invoke agents, we should make sure we actually can kill them again. I mean, it's probably not our job to cleanup the signals if our tools are invoked in weird contexts, but at least we should make sure, that the subprocesses we invoke and intend to control work as intended.

2014-08-26sd-event: sd_event_prepare - stay in PREPARED if sd_event_wait() indicates ↵Tom Gundersen
that no sources are pending
2014-08-25sd-event: split run into prepare/wait/dispatchTom Gundersen
This will allow sd-event to be integrated into an external event loop, which in turn will allow (say) glib-based applications to use our various libraries, without manually integrating each of them (bus, rtnl, dhcp, ...). The external event-loop should integrate sd-event int he following way: Every iteration must start with a call to sd_event_prepare(), which will return 0 if no event sources are ready to be processed, a positive value if they are and a negative value on error. sd_event_prepare() may only be called following sd_event_dispatch(); a call to sd_event_wait() indicating that no sources are ready to be dispatched; or a failed call to sd_event_dispatch() or sd_event_wait(). A successful call to sd_event_prepare() indicating that no event sources are ready to be dispatched must be followed by a call to sd_event_wait(), which will return 0 if it timed out without event sources being ready to be processed, a negative value on error and a positive value otherwise. sd_event_wait() may only be called following a successful call to sd_event_prepare() indicating that no event sources are ready to be dispatched. If sd_event_wait() indicates that some events sources are ready to be dispatched, it must be followed by a call to sd_event_dispatch(). This is the only time sd_event_dispatch() may be called.
2014-08-25systemctl: fix broken list-unit-files with --rootLukas Nykryn
This patch modifies unit_file_get_list which will now return hashmap of structures where f->path is *without* root_dir prefix. This change should be ok, because current code either does not use root_dir at all or calls basename() on the f->path.

2014-08-22core: split up "starting" manager state into "initializing" and "starting"Lennart Poettering
We'll stay in "initializing" until basic.target has reached, at which point we will enter "starting". This is preparation so that we can change the startip timeout to only apply to the first phase of startup, not the full procedure.

2014-08-22core: add support for a configurable system-wide start-up timeoutLennart Poettering
When this system-wide start-up timeout is hit we execute one of the failure actions already implemented for services that fail. This should not only be useful on embedded devices, but also on laptops which have the power-button reachable when the lid is closed. This devices, when in a backpack might get powered on by accident due to the easily reachable power button. We want to make sure that the system turns itself off if it starts up due this after a while. When the system manages to fully start-up logind will suspend the machine by default if the lid is closed. However, in some cases we don't even get as far as logind, and the boot hangs much earlier, for example because we ask for a LUKS password that nobody ever enters. Yeah, this is a real-life problem on my Yoga 13, which has one of those easily accessible power buttons, even if the device is closed.

2014-08-22shared: add MAXSIZE() and use it in resolvedDavid Herrmann
The MAXSIZE() macro takes two types and returns the size of the larger one. It is much simpler to use than MAX(sizeof(A), sizeof(B)) and also avoids any compiler-extensions, unlike CONST_MAX() and MAX() (which are needed to avoid evaluating arguments more than once). This was suggested by Daniele Nicolodi <daniele@grinta.net>. Also make resolved use this macro instead of CONST_MAX(). This enhances readability quite a bit.
