202b76ae1a Use provided buffer in dns_resource_key_to_string
When the buffer is allocated on the stack we do not have to check for
failure everywhere. This is especially useful in debug statements, because
we can put dns_resource_key_to_string() call in the debug statement, and
we do not need a seperate if (log_level >= LOG_DEBUG) for the conversion.

dns_resource_key_to_string() is changed not to provide any whitespace
padding. Most callers were stripping the whitespace with strstrip(),
and it did not look to well anyway. systemd-resolve output is not column
aligned anymore.

The result of the conversion is not stored in DnsTransaction object
anymore. It is used only for debugging, so it seems fine to generate it
when needed.

Various debug statements are extended to provide more information.

c77d26122a resolved: make sure to normalize all domain names returned via the bus
Most domain names we deal with are normalized anyway (since we read them that
way from DNS packets), but some might not (because they are synthesized from
unnormalized configuration or so), hence make sure to normalize all names
before passing them out to clients, to be fully deterministic.

Note that internally we are process normalized and non-normalized names the
same way, and while comparing them ignore the differences due to unnormalized
names. However, that internal implementation detail really shouldn't spill out
the clients, hence make sure to clean it all up.

9dc907f9c9 networkd: rework idle detection logic of networkd
This patch makes networkd stay around as long as there is more than just a
loopback interface around, or the loopback device isn't fully probed yet, or
the loopback device has a .network file attached.

In essence, this means networkd stays around now continously as it should,
unless it is running in some (container?) environment that really has no
interface except a loopback device.

Fixes #2577.

de08570050 build-sys: fix type detection
Before this patch existence of char16_t, char32_t, key_serial_t was checked
with AC_CHECK_DECLS() which doesn't actually work for types. Correct this to
use AC_CHECK_TYPES() instead.

Also, while we are at it, change the check for memfd_create() to use
AC_CHECK_DECLS() instead of AC_CHECK_FUNCS(). This is a better choice, since a
couple of syscalls are defined by glibc but not exported in the header files
(pivot_root() for example), and we hence should probably be more picky with
memfd_create() too, which glibc might decide to expose one day, but not
necessarily in the headers too.

61ecb465b1 resolved: turn on DNSSEC by default, unless configured otherwise
Let's make sure DNSSEC gets more testing, by defaulting DNSSEC to
"allow-downgrade" mode. Since distros should probably not ship DNSSEC enabled
by default add a configure switch to disable this again.

DNSSEC in "allow-downgrade" mode should mostly work without affecting user
experience. There's one exception: some captive portal systems rewrite DNS in
order to redirect HTTP traffic to the captive portal. If these systems
implement DNS servers that are otherwise DNSSEC-capable (which in fact is
pretty unlikely, but still...), then this will result in the captive portal
being inaccessible. To fix this support in NetworkManager (or any other network
management solution that does captive portal detection) is required, which
simply turns off DNSSEC during the captive portal detection, and resets it back
to the default (i.e. on) after captive portal authentication is complete.

4524439edb systemctl: include -M or -H arguments in the hint
https://github.com/systemd/systemd/issues/2431

Some newlines are added, but the output will still exceed 80 columns in many
cases. The fallback for oom conditions is changed from "n/a" to something
"<service>", and a similar pattern is used for the new code. This way we
have a realistic fallback for oom, which seems nicer than making the whole
function return an error code which would then have to be propagated.

$ systemctl -M fedora-rawhide restart systemd-networkd.service
Job for systemd-networkd.service failed because start of the service was attempted too often.
See "systemctl -M fedora-rawhide status systemd-networkd.service" and "journalctl -M fedora-rawhide -xe" for details.
To force a start use "systemctl -M fedora-rawhide reset-failed systemd-networkd.service"
followed by "systemctl -M fedora-rawhide start systemd-networkd.service" again.

ebf30a086d time-util: introduce deserialize_timestamp_value()
The time-util.c provides dual_timestamp_deserialize() function to
convert value to usec_t and set it as value of ts->monotonic and
ts->realtime.

There are some places in code which do the same but only for one
clockid_t (realtime or monotonic), when dual_timestamp_deserialize()
sets value of both.

This patch introduces the deserialize_timestamp_value() which converts
 a given value to usec_t and write it to a given timestamp.

c3be369faa resolved: extend ResolveHostname() bus call so that it can parse IP addresses
If the hostname passed to ResolveHostname() is actually an IP address that is
correctly formatted as string parse it as such, avoid any DNS traffic and
return the data in parsed form.

This is useful for clients which can simply call the bus function now without
caring about the precise formatting of specified hostnames. This mimics
getaddrinfo()'s behaviour with the AI_NUMERICHOST flag set.

Note that this logic is only implemented for ResolveHostname(), but not for
calls such as ResolveRecord(), for which only DNS domain names may be used as
input.

The "authenticated" flag is set for look-ups of this type, after all no
untrusted network traffic is involved.

ee116b54a3 resolved: rename "SearchDomains" property in the Manager interface to "Domains"
Another property name fuck-up. The property contains both search and routing
domains and hence should be exposed as "Domains" rather than "SearchDomains".

The counterpart in the Link object was correctly named, and the
SetLinkDomains() and SetDomains() setter calls too, hence let's get this right,
too.

(Yepp, a minor API break actually, but given that this was so far not
documented, and only 3 days public let's fix this now)

c2cf6e0b9d resolved: fix DNSSECSupported Link object property name
By mistake the "DNSSECSupported" bus property of the Link object got named
"DNSSECSupport". Internally, it's named correctly, and the counterpart on the
"Manager" object got named correctly too.

Technically this rename is an API break, but given that the interface is not
documented or widely announced yet, and just 3 days in a published release,
let's just fix this, and hope nobody notices.

cf98937cc7 activate: allow multiple, possibly invalid, fd names
Previous code only allowed a single name to be passed, and duplicated
it over all descriptors. For the sake of testing, allow different
names and in arbitrary number. If just one is given, duplicate it
to match the number of sockets. This matches previuos behaviour.

Since this is a testing tool, it seems useful to allow passing invalid
names to test application behaviour with invalid names. Hence, only
warn. When warning, escape the name.
