resolved: use reference counting for DnsQueryCandidate objects
Follow-up for
4ea8b443de. The logic that manages DnsQueryCandidate is rather
complicated: a calls to dns_query_complete() that wants to destroy a
DnsQueryCandidate can be nested inside a deep chain of calls. Using reference
counts seems like the simplest approach.
DnsSearchDomain already uses reference counting.
This patch effectively brings dns_query_candidate_go() to the state before
4ea8b443de, but wraps the iteration over DnsQueryCandidate.transactions in
dns_query_candidate_ref+dns_query_candidate_unref.

tree-wide: ignore messages with too long control data
Apparently SELinux inserts control data into AF_UNIX datagrams where we
don't expect it, thus miscalculating the control data. This looks like
something to fix in SELinux, but we still should handle this gracefully
and just drop the offending datagram and continue.
recvmsg_safe() actually already drops the datagram, it's just a matter
of actually ignoring EXFULL (which it generates if control data is too
large) in the right places.
This does this wherever an AF_UNIX/SOCK_DGRAM socket is used with
recvmsg_safe() that is not just internal communication.

systemctl: warn when importing environment variables with control characters
I don't think it is useful to warn about about environemnt variables where the user
explicitly configured some value. If they went through the effort of escaping the cc
to include it in the setting (e.g. Environment="VAR=\efoo"), and we pass this through,
there isn't anything to warn about. This also applies to 'systemctl set-environment',
where the variable name and value are passed as arguments.
The only case where the warning *might* be useful is where the user might be
surprised by the value. This occurs when importing variables from the inherited
environment, i.e. in 'systemctl import-environment'. In not convinced that this is
useful, since the user better control their shell environment anyway.
$ systemctl import-environment
Calling import-environment without a list of variable names is deprecated.
Environment variable $LESS_TERMCAP_mb contains control characters, importing anyway.
Environment variable $LESS_TERMCAP_md contains control characters, importing anyway.
Environment variable $LESS_TERMCAP_me contains control characters, importing anyway.
Environment variable $LESS_TERMCAP_se contains control characters, importing anyway.
Environment variable $LESS_TERMCAP_so contains control characters, importing anyway.

Allow control characters in environment variable values
So far, we would allow certain control characters (NL since
b4346b9a77bc6129dd3e, TAB since
6294aa76d818e831de45), but not others. Having
other control characters in environment variable *value* is expected and widely
used, for various prompts like $LESS, $LESS_TERMCAP_*, and other similar
variables. The typical environment exported by bash already contains a dozen or
so such variables, so programs need to handle them.
We handle then correctly too, for example in 'systemctl show-environment',
since
804ee07c1370d49aa9a. But we would still disallow setting such variables
by the user, in unit file Environment= and in set-environment/import-environment
operations. This is unexpected and confusing and doesn't help with anything
because such variables are present in the environment through other means.
When printing such variables, 'show-environment' escapes all special
characters, so variables with control characters are plainly visible.
In other uses, e.g. 'cat -v' can be used in similar fashion. This would already
need to be done to suppress color codes starting with \[.
Note that we still forbid invalid utf-8 with this patch. (Control characters
are valid, since they are valid 7-bit ascii.) I'm not sure if we should do
that, but since people haven't been actually asking for invalid utf-8, and only
for control characters, and invalid utf-8 causes other issues, I think it's OK
to leave this unchanged.

This variable (a.k.a. rootlibexecdir), was exposed through the .pc file, but

The .pc file must be located in the package that provides libraries, which
pulls in a lot of dependencies. In Fedora, the macros are split out to a
separate package so that other packages which need to refer to some systemd
path but don't otherwise require it, can only pull in the (much smaller and
dependency-less) macros package. zram-generator uses the path to specify the

change to add an 'alias' state, but it was wired to systemctl
only when running in 'client-side' mode. Return success as
expected and documented also when running in 'server-mode'.

man/systemd.netdev: clarify the wireguard AllowedIPs= setting
`AllowedIPs=` only affects "routing inside the network interface
itself", as in, which wireguard peer packets with a specific destination
address are sent to, and what source addresses are accepted from which
peer.
To cause packets to be sent via wireguard in first place, a route via
that interface needs to be added - either in the `[Routes]` section on
the `.network` matching the wireguard interface, or outside of networkd.
This is a common cause of misunderstanding, because tools like wg-quick
also add routes to the interface. However, those tools are meant as a
"extremely simple script for easily bringing up a WireGuard interface,
suitable for a few common use cases (from their manpage).
Networkd also should support other usecases - like setting AllowedIPs to
0.0.0.0/0 and ::/0 and having a dynamic routing protocol setting more
specific routes (or the user manually setting them).

sd-bus: make credential acquisition more graceful
So far when asked for augmented bus credentials and the process was
already gone we'd fail fatally. Let's make this graceful instead, and
never allow augmenting fail due to PID having vanished — unless the
augmenting is the explicit and only purpose of the requested operation.
This should be safe as clients have to explicitly query the acquired
creds anyway and handle if they couldn't be acquired. Moreover we
already handle permission problems gracefully, thus clients must be
ready to deal with missing creds.
This is useful to make selinux authorization work for short-lived client
proceses. PReviously we'd augment creds to have more info to log about
(the selinux decision would not be based on augmented data however,
because that'd be unsafe), and would fail if we couldn't get it. Now,
we'll try to acquire the data, but if we cannot acquire it, we'll still
do the selinux check, except that logging will be more limited.

test-login: skip consistency checks when logind is not active

some are derived from the cgroup path, but others use the data serialized

When the tests are executed under Fedora's mock, without systemd-spawn

the "outside" cgroup path is visible, so sd_pid_get_unit() and
sd_pid_get_session() work, but sd_session_is_active() and other functions

cryptsetup: Fix crypto device missing issue after bootup
Normally, the udev rules operate on "change" events. But when
coldplugging, there's an "add" event present. The udev rules have to
recognize this and do some actions in this particular situation, too.
Also, we don't want the nodes to be created prematurely on "add"
events while not coldplugging. The udev rules will check
DM_UDEV_PRIMARY_SOURCE_FLAG to see if the device was activated
correctly before and if not, it ignore the "add" event totally.
This way the udev rules can support udev triggers generating "add"
events (e.g. "udevadm trigger --action=add" or
"echo add > /sys/block/<dm_device>/uevent").
In this case, the udevd service is started after
systemd-cryptsetup@config.service, is started, which will cause udevd
service to miss the "change" uevent with DM_UDEV_PRIMARY_SOURCE_FLAG
flag generated by systemd-cryptsetup@config.service. To solve this
issue, we let the cryptsetup service be started after the udevd
service.

the sound devices are created.

manager: Fix HW watchdog when systemd starts before driver loaded
When manager_{set|override}_watchdog is called, set the watchdog timeout
regardless of whether the hardware watchdog was successfully initialized. If
the watchdog was requested but could not be initialized, then instead of
pinging it, attempt to initialize it again. This ensures that the hardware
watchdog is initialized even if the kernel module for it isn't loaded when
systemd starts (which is quite likely, unless it is compiled in).
This builds on work by @danc86 in https://github.com/systemd/systemd/pull/17460,
but fixes the issue of not updating the watchdog timeout with the actual value
from the hardware.
Fixes https://github.com/systemd/systemd/issues/17838

resolved: never allow _gateway lookups to go to the network
Make them rather fail than go to the network.
Previously we'd filter them on LLMNR (explicitly) and MDNS (implicitly,
because it doesn't have .local suffix), but not on DNS.
In order to make _gateway truly reliable, let's not allow it to go to
DNS either, and keep it local.
This is particular relevant, as clients can now request lookups without
local RR synthesis, where we'd rather have NXDOMAIN returned for
_gateway than have it hit the network.

virt: Properly detect nested UML inside another hypervisor
UML runs as a user-process so it can quite easily be ran inside of
another hypervisor, for instance inside a KVM instance. UML passes
through the CPUID from the host machine so in this case detect_vm
