This adds the rules and starts those targets also for user instances.
Fixes#12330.
This suppress the following warning:
```
systemd-udevd[437]: Config file /usr/lib/systemd/network/99-default.link
applies to device based on potentially unpredictable interface name 'wlan0'
```
Follow-up for 84ea567eb4.
In certain situations, the systemctl commands may fail (e.g. due to
missing shared libraries), but the 'script' continues and creates a
/testok file, marking the test incorrectly as passed. Let's fix this and
bail out immediately when a command exits with a non-zero exit code.
Running integration tests with ASan is somewhat tricky to begin with, as
we need to pre-load the ASan runtime DSO for certain services (like
dbus), otherwise they won't start or behave as expected. In case of gcc
this is pretty easy, as we need the runtime DSO during compilation, so
it's already present on the host system. For clang things get more
complicated, as ASan is compiled in statically by default, thus to
enable the necessary dynamic-ish behavior one needs to compile with
-shared-libasan and then correctly set LD_PRELOAD_PATH, as the runtime
libraries are not in a standard library path.
This fixes the accelerometer for the Linx 12V64.
Note that even though the configuration for both models is the same, the 12V64 and 12X64 are different models.
Only changing ownership back to root is not enough we also need to
change the access mode, otherwise the user might have set 666 first, and
thus allow everyone access before and after the chown().
Inspired by #12431 let's also rework chmod_and_chown() and make sure we
never add more rights to a file not owned by the right user.
Also, let's make chmod_and_chown() just a wrapper arond
fchmod_and_chown().
let's also change strategy: instead of chown()ing first and stating
after on failure and supressing errors, let's avoid the chown in the
firts place, in the interest on keeping things minimal.
Previously, logind's logind-session.h would define prototypes for
logind-session.c and logind-session-dbus.c. Split that out, so that
there's a separate logind-session-dbus.h for that. Similar for seats and
users as well as the manager itself.
This changes no code, just rearranges where protoypes are located.
Most of the operations one can do on sessions so far accepted an empty
session name as a shortcut for the caller's session. This is quite
useful traditionally, but much less useful than it used to be, since
most user code now (rightfully) runs in --user context, not in a
session.
With this change we tweak the logic a bit: we introduce the two special
session and seat names "self" and "auto". The former refers to the
session/seat the client is in, and is hence mostly equivalent to te
empty string "" as before. However, the latter refers to the
session/seat the client is in if that exists, with a fallback of the
user's display session if not. Clients can hence reference "auto"
instead of the empty string if they really don't want to think much
about sessions.
Why "self" btw? Previously, we'd already expose a special dbus object
with the path /org/freedesktop/login1/session/self (and similar for the
seat), matching what the empty string did for bus calls that took a
session name. With this scheme we reuse this identifier and introduce
"auto" in a similar way.
Of course this means real-life seats and sessions can never be named
"self" or "auto", but they aren't anyway: valid seat names have to start
with "seat" anyway, and sessions are generated server-side as either a
numeric value or "c" suffixed with a counter ID.
