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
2016-02-01core: fix support for transient resource limit propertiesLennart Poettering
Make sure we can properly process resource limit properties. Specifically, allow transient configuration of both the soft and hard limit, the same way from the unit files. Previously, only the the hard rlimits could be configured but they'd implicitly spill into the soft hard rlimits. This also updates the client-side code to be able to parse hard/soft resource limit specifications. Since we need to serialize two properties in bus_append_unit_property_assignment() now, the marshalling of the container around it is now moved into the function itself. This has the benefit of shortening the calling code. As a side effect this now beefs up the rlimit parser of "systemctl set-property" to understand time and disk sizes where that's appropriate.
2016-02-01resolve: work around clang limitationLennart Poettering
clang is apparently not smart enough to detect when a switch statement contains case statements for all possible values of the used type. Work around that. (And while we are at it, normalize indentation a bit) Fixes: #2504
2016-02-01shared: simplify parsing of bus properties a bitLennart Poettering
Let's write the property name and value in one call, when that's possible, shorthing our code a bit.
2016-02-01core: when saving timer unit time values, store them in raw µsLennart Poettering
Let's simplify things a bit, and make sure we don't lose accuracy.
2016-02-01core: fix handling of AccuracyUSec and RandomDelayUSec bus propertiesLennart Poettering
Clear up some confusion regarding the USec and Sec suffixes we use. In configuration files we usually use the Sec suffix, to indicate the implied time unit if none is specified. The respective bus properties however use the USec property, since they expose 64bit unsigned integers containing time in µs. Before this patch timer units exposed a bus property AccuracyUSec (which hence is the correct name) but when parsing transient property data would look for AccuracySec instead (which is incorrect). This patch ensures we look for AccuracySec correctly, but keeps the code for AccuracyUSec in place for compatibility, but adds a warning to ensure that apps are updated to use the right property.
2016-02-01basic: add new rlimit_format() callLennart Poettering
This formats a struct rlimit the way rlimit_parse() expects it.

2016-02-01core: move parsing of rlimits into rlimit-util.[ch]Lennart Poettering
This way we can reuse it for parsing rlimit settings in "systemctl set-property" and related commands.
2016-02-01core: store for each unit when the last low-level unit state change took placeLennart Poettering
This adds a new timestamp field to the Unit struct, storing when the last low-level state change took place, and make sure this is restored after a daemon reload. This new field is useful to allow restarting of per-state timers exactly where they originally started.
2016-02-01sd-event: permit a USEC_INFINITY timeout as an alternative to a disabling an ↵Lennart Poettering
event source This should simplify handling of time events in clients and is in-line with the USEC_INFINITY macro we already have. This way setting a timeout to 0 indicates "elapse immediately", and a timeout of USEC_INFINITY "elapse never".

2016-02-01resolved: rework what ResolveHostname() with family == AF_UNSPEC meansLennart Poettering
Previously, if a hostanem is resolved with AF_UNSPEC specified, this would be used as indication to resolve both an AF_INET and an AF_INET6 address. With this change this logic is altered: an AF_INET address is only resolved if there's actually a routable IPv4 address on the specific interface, and similar an AF_INET6 address is only resolved if there's a routable IPv6 address. With this in place, it's ensured that the returned data is actually connectable by applications. This logic mimics glibc's resolver behaviour. Note that if the client asks explicitly for AF_INET or AF_INET6 it will get what it asked for. This also simplifies the logic how it is determined whether a specific lookup shall take place on a scope. Specifically, the checks with dns_scope_good_key() are now moved out of the transaction code and into the query code, so that we don't even create a transaction object on a specific scope if we cannot execute the resolution on it anyway.

Make sure we construct the full environment block on the heap, so that we can clean things up properly if execv() fails.

Also introduce sd_journal_has_runtime_files() and sd_journal_has_persistent_files() to the public API. These functions can be used to easily find out if the open journal files are runtime and/or persistent.

mode_t is unsigned, so MODE_INVALID < 0 can never be true. This fixes a possible DoS where any user could fill /run by writing to a world-writable /run/systemd/show-status.
2016-01-29resolved: log server type when switching serversZbigniew Jędrzejewski-Szmek
I'm not defining _DNS_SERVER_TYPE_MAX/INVALID as usual in the enum, because it wouldn't be used, and then gcc would complain that various enums don't test for _DNS_SERVER_TYPE_MAX. It seems better to define the macro rather than add assert_not_reached() in multiple places.

2016-01-29udev: net_id - for ccw bus, shorten the identifier and stip leading zerosDimitri John Ledkov
The commmon case default qeth link is enccw0.0.0600 is rather long. Thus strip leading zeros (which doesn't make the bus_id unstable), similar to the PCI domain case. Also 'ccw' is redundant on S/390, as there aren't really other buses available which could have qeth driver interfaces. Not sure why this code is even compiled on non-s390[x] platforms. But to distinguish from e.g. MAC stable names shorten the suffix to just 'c'. Thus enccw0.0.0600 becomes enc600.
