d33b6cf343 resolved: try to detect fritz.box-style private DNS zones, and downgrade to non-DNSSEC mode for them
This adds logic to detect cases like the Fritz!Box routers which serve
a private DNS domain "fritz.box" under the TLD "box" that does not
exist in the root servers. If this is detected DNSSEC validation is
turned off for this private domain, thus improving compatibility with
such private DNS zones.

This should be fairly secure as we first rely on the proof that .box
does not exist before this logic is applied. Nevertheless the logic is
only enabled for DNSSEC=allow-downgrade mode.

This logic does not work for routers that set up a full DNS zone directly
under a non-existing TLD, as in that case we cannot prove
that the domain is truly non-existing according to the root servers.

b43d75c378 importd: drop dkr support
The current code is not compatible with current dkr protocols anyway,
and dkr has a different focus ("microservices") than nspawn anyway
("whole machine containers"), hence drop support for it, we cannot
reasonably keep this up to date, and it creates the impression we'd
actually care for the microservices usecase.

4afd3348c7 tree-wide: expose "p"-suffix unref calls in public APIs to make gcc cleanup easy
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.

The name RandomSec is too generic: "Sec" just specifies the default

that should give the user general idea what the setting does without
looking at documentation.

a51c10485a resolved: add a generic DnsSearchDomain concept
With this change, we add a new object to resolved, "DnsSearchDomain="
which wraps a search domain. This is then used to introduce a global
search domain list, in addition to the existing per-link search domain
list which is reword to make use of this new object too.

This is preparation for implement proper unicast DNS search domain
support.

91518d20dd core: support <soft:hard> ranges for RLIMIT options
The new parser supports:

 <value>       - specify both limits to the same value
 <soft:hard>   - specify both limits

the size or time specific suffixes are supported, for example

  LimitRTTIME=1sec
  LimitAS=4G:16G

The patch introduces parse_rlimit_range() and rlim type (size, sec,
usec, etc.) specific parsers. No code is duplicated now.

The patch also sync docs for DefaultLimitXXX= and LimitXXX=.

958caa58c0 man: include the target name when linking to man pages in html output
Links like http://www.freedesktop.org/software/systemd/man/systemd.socket.html
are changed to http://www.freedesktop.org/software/systemd/man/systemd.socket.html#Accept=.

This implementation is quick & dirty, and misses various corner
cases. A fairly important one is that when a few directives share the
same anchor (which happens when multiple directives are described in
the same paragraph), generated links for everything except the first
one link to an invalid anchor. Another shortcoming is that the
formatting does not use the proper generateID machinery, so the anchor
name could be wrong in some cases. But it seems to work for a large
percentage of links, so seems to be an improvement in usability. When
the anchor is missing, we land at the top of the page, which is the
same as before. If the anchor were to point to different spot, this
would be more confusing... Not sure if that ever happens. Anyway, the
user should be able to recover from landing on the wrong place in the
page.

(Mostly) fixes https://github.com/systemd/systemd/issues/1956.

e9fd88f2e9 core: allow 'SetUnitProperties()' to run on inactive units too
'set-property' has been primarly designed to change some properties of
*active* units.

However it can easily work on inactive units as well. In that case
changes are only saved in a drop-in for futur uses and changes will be
effective when unit will be started.

Actually it already works on inactive units but that was not
documented and not fully supported. Indeed the inactive units had to
be known by the manager otherwise it was reported as not loaded:

 $ systemctl status my-test.service
 * my-test.service - My Testing Unit
    Loaded: loaded (/etc/systemd/system/my-test.service; static; vendor preset: disabled)
   Drop-In: /etc/systemd/system/my-test.service.d
    Active: inactive (dead)

 $ systemctl set-property my-test.service MemoryLimit=1000000
 Failed to set unit properties on my-test.service: Unit my-test.service is not loaded.

[ Note: that the unit load state reported by the 'status' command
  might be confusing since it claimed the unit as loaded but
  'set-property' reported the contrary. ]

One can possibily workaround this by making the unit a dependency of
another active unit so the manager will keep it around:

 $ systemctl add-wants multi-user.target my-test.service
 Created symlink from /etc/systemd/system/multi-user.target.wants/my-test.service to /etc/systemd/system/my-test.service.

 $ systemctl set-property my-test.service MemoryLimit=1000000

 $ systemctl status my-test.service
 * my-test.service - My Testing Unit
    Loaded: loaded (/etc/systemd/system/my-test.service; enabled; vendor preset: disabled)
   Drop-In: /etc/systemd/system/my-test.service.d
            `-50-MemoryLimit.conf
    Active: inactive (dead)

This patch simply forces 'SetUnitProperties()' to load the unit if
it's not already the case.

It also documents the fact that 'set-property' can be used on inactive
units.

3e0c30ac56 core: add RemainAfterElapse= setting to timer units
Previously, after a timer unit elapsed we'd leave it around for good,
which has the nice benefit that starting a timer that shall trigger at a
specific point in time multiple times will only result in one trigger
instead of possibly many. With this change a new option
RemainAfterElapse= is added. It defaults to "true", to mimic the old
behaviour. If set to "false" timer units will be unloaded after they
elapsed. This is specifically useful for transient timer units.

2904e949f2 tmpfiles: create subvolumes for "v", "q", and "Q" only if / is a subvolume
It's not a good idea to create subvolumes for parts of the OS tree (such
as /home, or /var) if the root directory is not a subvolume too. We
shouldn't assume control of "heavier" objects such as subvolumes, if the
originating object (the root directory) is a "light-weight" object, i.e.
a plain directory.

Effectively this means that chroot() environments that are run on a
plain directory do not have to deal with problems around systemd
creating subvolumes that cannot be removed with a simple "rm" anymore.
However, if the chroot manager creates a proper subvolume for such an
environment it will also get further subvolumes placed in there, under
the assumption that the manager understands the concept of subvolumes in
that case.
