The name RandomSec is too generic: "Sec" just specifies the default
unit type, and "Random" by itself is not enough. Rename to something
that should give the user general idea what the setting does without
looking at documentation.
It may be unexpected to find a CNAME record when doing a reverse lookup, as we
expect to find a PTR record directly. However, it is explicitly supported
according to <https://tools.ietf.org/html/rfc2181#section-10.2>, and there
seems to be no benefit to not supporting it.
The assumption that no NSEC bitmap could be empty due to the presence of the bit representing
the record itself turns out to be flawed. See (the admittedly experimental) RFC4956 for a
counter example.
Commit 5e5b137a (networkd: link - drop foreign config when configuring
link) introduced a regression where addresses (including 127.0.0.1) are
removed from loopback device.
Do not handle loopback device when removing foreign configs.

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=.

Fixes backward/forward incompatibility errors on spawning.
For example:
$ sudo make run
...
Failed to register machine: Cannot set property TasksMax, or unknown
property.
$ ../../systemd-nspawn --version
systemd 228
$ systemd-nspawn --version
systemd 225
This also adds client-side support for this to systemd-resolve-host.
Note that the ResolveService() API can deal both with DNS-SD service
(consisting of service name, type and domain), as well as classic SRV
services (consisting just of a type and a domain), all exposed in the
same call.
This patch also reworks CNAME handling in order to reuse it between
hostname, RR and service lookups.
In contrast to Avahi and Bonjour, this new API will actually reolve the
A/AAAA RRs the SRV RRs point to in one go (unless this is explicitly
disabled). This normally comes for free, as these RRs are sent along
the SRV responses anyway, hence let's make use of that. This makes the
API considerably easier to use, as a single ResolveService() invocation
will return all necessary data to pick a server and connect() to it.
Note that this only implements the DNS-SD resolving step, it does not
implement DNS-SD browsing, as that makes sense primarily on mDNS, due to
its continuous nature.
This adds dns_service_join() and dns_service_split() which may be used
to concatenate a DNS-SD service name, am SRV service type string, and a
domain name into a full resolvable DNS domain name string. If the
service name is specified as NULL, only the type and domain are
appended, to implement classic, non-DNS-SD SRV lookups.
The reverse is dns_service_split() which takes the full name, and split
it into the three components again.
RFC 6763 is very clear that TXT RRs should allow arbitrary binary
content, hence let's actually accept that. This also means accepting NUL
bytes in the middle of strings.
