There's still some breaking changes we want to make to sysupdated, but
they'll potentially take months and we don't want to block the systemd
release for that long. So, we can instead mark sysupdate's API as
unstable
Let's ramp up security for system user accounts, at least where
possible, by creating them fully locked (instead of just with an invalid
password). This matters when taking non-password (i.e. SSH) logins into
account.
Fixes: #13522
We should avoid unnecessary abbreviations for such messages, and this
puts a maximum limit on things, hence it should indicate this in the
name.
Moreover, matches is a bit confusing, since most people will probably
call "busctl monitor" without any match specification, i.e. zero
matches, but that's not what was meant here at all.
Also, add a brief switch for this (-N) since I figure in particular
"-N1" might be a frequent operation people might want to use.

We are going to output a series of JSON objects, hence let's
automatically enable JSON-SEQ output mode, as we usually do.
"jq --seq" supports this natively, hence this should not really restrict
us.

This applies the existing SocketUser=/SocketGroup= options to units
defining a POSIX message queue, bringing them in line with UNIX
sockets and FIFOs. They are set on the file descriptor rather than
a file system path because the /dev/mqueue path interface is an
optional mount unit.
This commit adds two settings private and strict to
the ProtectControlGroups= property. Private will unshare the cgroup
namespace and mount a read-write private cgroup2 filesystem at /sys/fs/cgroup.
Strict does the same except the mount is read-only. Since the unit is
running in a cgroup namespace, the new root of /sys/fs/cgroup is the unit's
own cgroup.
We also add a new dbus property ProtectControlGroupsEx which accepts strings
instead of boolean. This will allow users to use private/strict via dbus
and systemd-run in addition to service files.
Note private and strict fall back to no and yes respectively if the kernel
doesn't support cgroup2 or system is not using unified hierarchy.

The goal of RestartMode=direct is to make restarts invisible
to dependents, so auto restart jobs shouldn't bring them down
at all. So far we only skipped going through failed/dead states
in service_enter_dead(), i.e. the unit would never be considered
dead. But when constructing restart transaction, the stop job
would be propagated to dependents. Consider the following 2 units:
dependent.target:
[Unit]
BindsTo=a.service
After=a.service
a.service:
[Service]
ExecStart=bash -c 'sleep 100 && exit 1'
Restart=on-failure
RestartMode=direct
Before this commit, even though BindsTo= isn't triggered since
a.service never failed, when a.service auto-restarts, dependent.target
is also restarted. Let's suppress it by using JOB_REPLACE instead of
JOB_RESTART_DEPENDENCIES in service_enter_restart().
Fixes#34758
The example above is subtly different from the original report,
to illustrate that the new behavior makes sense for less exotic
use cases too.
No functional change, but let's print yes/no rather than on/off in systemd-analyze.
Similar to 2e8a581b9cc1132743c2341fc334461096266ad4 and
edd3f4d9b7a63dc9a142ef20119e80d1d9527f2f.
(Note, the commit messages of those commits are wrong, as
parse_boolean() supports on/off anyway.)
This makes use of the infra introduced in 229d4a980607e9478cf1935793652ddd9a14618b to indicate visually on each prompt that we are in superuser mode temporarily.
pick ad5de3222f userdbctl: add some basic client-side filtering
This adds some basic client-side user/group filtering to "userdbctl":
1. by uid/gid min/max
2. by user "disposition" (i.e. show only regular users with "userdbctl
user -R")
3. by fuzzy name (i.e. search by substring/levenshtein of user name,
real name, and other identifiers of the user/group record).
In the long run we also want to support this server side, but let's
start out with doing this client-side, since many backends won't support
server-side filtering anytime soon anyway, so we need it in either case.
Clients should be able to know if the idle logic is available on a
session without secondary knowledge about the session class. Let's hence
expose a property for that.
Similar for the screen lock concept.

This option will control the use of DNR for choosing DNS servers on the
link. Defaults to the value of UseDNS so that in most cases they will be
toggled together.
Optional features allow distros to define sets of transfers that can
be enabled or disabled by the system administrator. This is useful for
situations where a distro may want to ship some resources version-locked
to the core OS, but many people have no need for the resource, such as:
development tools/compilers, drivers for specialized hardware, language
packs, etc
We also rename sysupdate.d/*.conf -> sysupdate.d/*.transfer, because
now there are more than one type of definition in sysupdate.d/. For
backwards compat, we still load *.conf files as long as no *.transfer
files are found and the *.conf files don't try to declare themselves
as part of any features

This will allow units (scopes/slices/services) to override the default
systemd-oomd setting DefaultMemoryPressureDurationSec=.
The semantics of ManagedOOMMemoryPressureDurationSec= are:
- If >= 1 second, overrides DefaultMemoryPressureDurationSec= from oomd.conf
- If is empty, uses DefaultMemoryPressureDurationSec= from oomd.conf
- Ignored if ManagedOOMMemoryPressure= is not "kill"
- Disallowed if < 1 second
Note the corresponding dbus property is DefaultMemoryPressureDurationUSec
which is in microseconds. This is consistent with other time-based
dbus properties.
