2016-02-26clock-util: make clock_is_localtime() testable and add initial testsMartin Pitt
Add path argument to clock_is_localtime() and default to "/etc/adjtime" if it's NULL. This makes the function testable. Add test-clock: initial test cases for some scenarios, using a temporary file. This also checks the behaviour with a NULL (i. e. the system's /etc/adjtime) file.

tree-wide: merge pager_open_if_enabled() to the pager_open()
2016-02-26tree-wide: merge pager_open_if_enabled() to the pager_open()Alexander Kuleshov
Many subsystems define own pager_open_if_enabled() function which checks '--no-pager' command line argument and open pager depends on its value. All implementations of pager_open_if_enabled() are the same. Let's merger this function with pager_open() from the shared/pager.c and remove pager_open_if_enabled() from all subsytems to prevent code duplication.
2016-02-22tree-wide: make ++/-- usage consistent WRT spacingVito Caputo
Throughout the tree there's spurious use of spaces separating ++ and -- operators from their respective operands. Make ++ and -- operator consistent with the majority of existing uses; discard the spaces.
2016-02-16main: no need to set errno manuallyAlexander Kuleshov
If we are not PID 1 and started as init, we executing systemctl with execv(). Here no need to set errno manually, because in a failure case, because the execv() anyway will set errno depends on a error.
2016-02-10core: set RLIMIT_CORE to unlimited by defaultLennart Poettering
The kernel sets RLIMIT_CORE to 0 by default. Let's bump this to unlimited by default (for systemd itself and all processes we fork off), so that the coredump hooks have an effect if they honour it. Bumping RLIMIT_CORE of course would have the effect that "core" files will end up on the system at various places, if no coredump hook is used. To avoid this, make sure PID1 sets the core pattern to the empty string by default, so that this logic is disabled. This change in defaults should be useful for all systems where coredump hooks are used, as it allows useful usage of RLIMIT_CORE from these hooks again. OTOH systems that expect that coredumps are placed under the name "core" in the current directory will break with this change. Given how questionnable this behaviour is, and given that no common distro makes use of this by default it shouldn't be too much of a loss. Also, the old behaviour may be restored by explicitly configuring a "core_pattern" of "core", and setting the default system RLIMIT_CORE to 0 again via system.conf.
2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.
2016-02-03resolved: apply epoch to system time from PID 1Lennart Poettering
For use in timesyncd we already defined a compile-time "epoch" value, which is based on the mtime of the NEWS file, and specifies a point in time we know lies in the past at runtime. timesyncd uses this to filter out nonsensical timestamp file data, and bump the system clock to a time that is after the build time of systemd. This patch adds similar bumping code to earliest PID 1 initialization, so that the system never continues operation with a clock that is in the 1970ies or even 1930s.
2016-02-03manager: print fatal error if early mount failedAlexander Kuleshov
The mount_setup_early() can fail and if it will occur, there is no sense to make selinux setup and etc.
2016-02-01core: rework unit timeout handling, and add new setting RuntimeMaxSec=Lennart Poettering
This clean-ups timeout handling in PID 1. Specifically, instead of storing 0 in internal timeout variables as indication for a disabled timeout, use USEC_INFINITY which is in-line with how we do this in the rest of our code (following the logic that 0 means "no", and USEC_INFINITY means "never"). This also replace all usec_t additions with invocations to usec_add(), so that USEC_INFINITY is properly propagated, and sd-event considers it has indication for turning off the event source. This also alters the deserialization of the units to restart timeouts from the time they were originally started from. Before this patch timeouts would be restarted beginning with the time of the deserialization, which could lead to artificially prolonged timeouts if a daemon reload took place. Finally, a new RuntimeMaxSec= setting is introduced for service units, that specifies a maximum runtime after which a specific service is forcibly terminated. This is useful to put time limits on time-intensive processing jobs. This also simplifies the various xyz_spawn() calls of the various types in that explicit distruction of the timers is removed, as that is done anyway by the state change handlers, and a state change is always done when the xyz_spawn() calls fail. Fixes: #2249

2016-01-12core: Add machine-id settingNils Carlson
Allow for overriding all other machine-ids which may be present on the system using a kernel command line systemd.machine_id or --machine-id= option. This is especially useful for network booted systems where the machine-id needs to be static, or for containers where a specific machine-id is wanted.
2016-01-12capabilities: keep bounding set in non-inverted format.Ismo Puustinen
Change the capability bounding set parser and logic so that the bounding set is kept as a positive set internally. This means that the set reflects those capabilities that we want to keep instead of drop.
2015-11-27tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easyLennart Poettering
GLIB has recently started to officially support the gcc cleanup attribute in its public API, hence let's do the same for our APIs. With this patch we'll define an xyz_unrefp() call for each public xyz_unref() call, to make it easy to use inside a __attribute__((cleanup())) expression. Then, all code is ported over to make use of this. The new calls are also documented in the man pages, with examples how to use them (well, I only added docs where the _unref() call itself already had docs, and the examples, only cover sd_bus_unrefp() and sd_event_unrefp()). This also renames sd_lldp_free() to sd_lldp_unref(), since that's how we tend to call our destructors these days. Note that this defines no public macro that wraps gcc's attribute and makes it easier to use. While I think it's our duty in the library to make our stuff easy to use, I figure it's not our duty to make gcc's own features easy to use on its own. Most likely, client code which wants to make use of this should define its own: #define _cleanup_(function) __attribute__((cleanup(function))) Or similar, to make the gcc feature easier to use. Making this logic public has the benefit that we can remove three header files whose only purpose was to define these functions internally. See #2008.

2015-11-12core: drop "override" flag when building transactionsLennart Poettering
Now that we don't have RequiresOverridable= and RequisiteOverridable= dependencies anymore, we can get rid of tracking the "override" boolean for jobs in the job engine, as it serves no purpose anymore. While we are at it, fix some error messages we print when invoking functions that take the override parameter.
2015-11-10defs: rework CONF_DIRS_NULSTR() macroLennart Poettering
The macro is generically useful for putting together search paths, hence let's make it truly generic, by dropping the implicit ".d" appending it does, and leave that to the caller. Also rename it from CONF_DIRS_NULSTR() to CONF_PATHS_NULSTR(), since it's not strictly about dirs that way, but any kind of file system path. Also, mark CONF_DIR_SPLIT_USR() as internal macro by renaming it to _CONF_PATHS_SPLIT_USR() so that the leading underscore indicates that it's internal.
2015-11-06core: support IEC suffixes for RLIMIT stuffKarel Zak
Let's make things more user-friendly and support for example LimitAS=16G rather than force users to always use LimitAS=16106127360. The change is relevant for options: [Default]Limit{FSIZE,DATA,STACK,CORE,RSS,AS,MEMLOCK,MSGQUEUE} The patch introduces config_parse_bytes_limit(), it's the same as config_parse_limit() but uses parse_size() tu support the suffixes.

2015-11-02core: drop check for /etc/mtabMartin Pitt
util-linux 2.27.1 now entirely stops looking at /etc/mtab, so we don't need to verify /etc/mtab during early boot any more. Later on, tmpfiles.d/etc.conf will fix /etc/mtab anyway, so there's not even a point in warning about it. Drop test_mtab() and bump the util-linux dependency to >= 2.17.1. Fixes #1495
