As in the previous commit, checking for both requirements and ordering seems
unnecessary. In practical cases, the mount will be pulled in by the rest
of the transaction, so ordering is the part that matters. (The setup is
racy without the ordering.) If we drop the second check, the admin can
just use After=tmp.mount to achieve the desired behaviour, without needing
to explicitly pull in the unit. This is easier to configure and more robust.
This changes the implementation introduced in
6156bec7a4.
Also actually describe the implemented behaviour in the man page.
In https://github.com/systemd/systemd/issues/28515, multiple people report that
services that have PrivateTmp=yes and DefaultDependencies=no fail to create the
temporary directories under /tmp, when /tmp is e.g. a bind mount or some other
kind of mount that takes more time.
Before PrivateTmp=disconnected was added, we didn't have a nice solution:
DefaultDependencies=no is used to start services very early, so we wouldn't
want to add a dependency on /tmp automatically. With PrivateTmp=disconnected we
have a fairly nice solution. Let's "upgrade" to this mode automatically.
Strictly speaking, it is a small compat break, but in practice it's unlikely to
matter for early-boot services whether their /tmp is private or disconnected.
The dependency on /tmp that is checked is After. I think this is enough,
since any tmp.mount would be pulled in by local-fs.target and the rest of
the transaction anyway, so we don't need to check more than After.
The asserts are relaxed, because now the two settings can now diverge
in either way.

[yhndnzj: fix unit_add_exec_dependencies() to handle the new
combination; add a comment in exec_needs_sys_admin()]
The only reason why ExecSharedRuntime.(var_)tmp_dir might
be suppressed is when (/var)/tmp/ is listed in InaccessiblePaths=,
in which case mount namespace is needed anyways. Moreover,
the current logic imposes a chicken-and-egg problem:
at various places in pid1 we'd need to check whether
the unit runs in a mountns, but the ExecSharedRuntime
may not be allocated for it just yet.
* Make sure we're not passing NULL to rmdir()
* Remove the inner "tmp" subdir as well, so that callers
can handle this transparently (e.g. exec_shared_runtime_make()
is not aware of the nested rmdir() requirements)
While at it, remove unneeded PROTECT_ERRNO.
These syscalls are part of a newer kernel API to replace interaction
with /proc/self/attr, with the goal of allowing LSM stacking. These are
being used now by e.g. libapparmor, so should be more easily available
to services using seccomp filtering.
test_sd_device_enumerator_filter_subsystem hangs forever in OBS builds,
as it waits for the udev queue to be drained. But this is not a booted
system, with systemd and udev, so nothing will do that.
Skip the test in that case.
The callback might drop the last ref to the slot object, and we still
want to access it. Hence do what we usually do in these cases: keep an
extra reference while processing the callback.
Links with link-local-only communication are typically peer-to-peer
links between two laptops or similar. In such cases it makes sense to be
able to see which device one is specifically connected to, hence let's
just enable LLDP for it. This doesn't leak any data really, given that
this is inherently local, and typically only used between isolated
systems that are under the same user's possession.
Background: I recently connected multiple laptops via thunderbolt networking
and was kinda annoyed not being able to see what system I was actually
talking to.
(Also, the file touched here is an example only anyway, so even if this
would leak too much info, it's not in effect by default)
The socket failed on boot due to a ordering problem caused by
systemd-sysusers running later and thus the socket group was still
missing. The socket unit can only start when systemd-sysusers created
the group.
Order the socket after systemd-sysusers.service to have the group
available.
Could ask to Bastien Nocera who originally commited the joysticks hwdb
integration
https://gitlab.freedesktop.org/libinput/libinput/-/merge_requests/1429#note_3338386
and stated that was for use in iio-sensor but later anything was done.
As the variable was never used replace it with the new variable actually
in the process to be use in libinput. Even more at least some of the
idea that was planed for ID_INPUT_JOYSTICK_INTEGRATION could be done in
libinput.
Actually ID_INPUT_JOYSTICK_INTEGRATION was never used anywhere, replace
it with ID_INTEGRATION.

This reverts commit 351b4dd123.
I'm pretty sure we should not create more of these multiplexer
interfaces, which in this specific also leads to a fair bit of
confusion: start/stop/reload-or-restart --marked all enqueue
all job types.
Instead, a dedicated verb will be introduced in later commits.
With v259, resolved can be used to replace Avahi for mDNS service
discovery and announcement. One key difference in the API is that Avahi
by default browses on all available interfaces by passing a special
`AVAHI_IF_UNSPEC` (-1) interface index value. With this change, passing
ifindex value `0` can be used to achieve the same , so this will work:
```
# Browse on all available interfaces
varlinkctl call --more unix:/run/systemd/resolve/io.systemd.Resolve \
io.systemd.Resolve.BrowseServices \
'{"domain":"local","type":"_display._tcp","ifindex":0,"flags":0}'
```
Not having to iterate through all interfaces on the client side then
also makes it more straight forward to build a resolve-avahi-compat
library for painlessly replacing Avahi with systemd-resolved.
A PoC compat lib requiring this change is available at
https://github.com/LorbusChris/resolve-avahi-compat
We've changed them to return additional values, which may be a breaking
change for desktop environments. In practice, it doesn't seem to be a
major issue. However, let's make sure to document the changes in the
NEWS anyway!
Currently, there's no way for a desktop environment to detect when a
systemd inhibitor has been added or removed. This means that a desktop
environment that wishes to show current inhibitors to the user will be
either forced to poll systemd or just use stale data.
Now, the desktop can listen for changed events on NCurrentInhibitors and
call GetInhibitors() in response to that.
Desktops cannot currently tell the difference between a power action
being set to challenge permanently (i.e. because the sysadmin wanted to
restrict the given user) and a power action being set to challenge
because it's temporarily inhibited.
Thus, a desktop might take an action that is valid in the first case but
not the second case. For instance: GNOME hides all of its automatic
suspend settings from the UI whenever a sleep inhibitor is active.
This now returns a new state: "inhibited". It communicates to the
desktop that the action is available normally, but at the moment the
desktop isn't allowed to perform the action due to an inhibitor.
