Let's systematically make sure that we link up the D-Bus interfaces from
the daemon man pages once in prose and once in short form at the bottom
("See Also"), for all daemons.
Also, add reverse links at the bottom of the D-Bus API docs.
Fixes: #34996
We have this in a similar fashion for the other APIs libsystemd
provides. Add the same for sd-varlink. There isn't too much on it for
now, but at least it's a start.
Also link it up everywhere.
Processes can easily survive the first kill operation we execute, hence
we shouldn't make strong claims about them having exited already. Let's
just say "likely" hence.
Fixes: #15032
Let's emphasize the privilege thing with a <caution> section.
Let's also point out that other D-Bus libraries are less restrictive
than sd-bus by default regarding permission access.
Fixes: #34735
This new setting allows unsharing the pid namespace in a unit. Because
you have to fork to get a process into a pid namespace, we fork in
systemd-executor to get into the new pid namespace. The parent then
sends the pid of the child process back to the manager and exits while
the child process continues on with the rest of exec_invoke() and then
executes the actual payload.
Communicating the child pid is done via a new pidref socket pair that is
set up on manager startup.
We unshare the PID namespace right before the mount namespace so we
mount procfs correctly. Note PrivatePIDs=yes always implies MountAPIVFS=yes
to mount procfs.
When running unprivileged in a user session, user namespace is set up first
to allow for PID namespace to be unshared. However, when running in
privileged mode, we unshare the user namespace last to ensure the user
namespace does not own the PID namespace and cannot break out of the sandbox.
Note we disallow Type=forking services from using PrivatePIDs=yes since the
init proess inside the PID namespace must not exit for other processes in
the namespace to exist.
Note Daan De Meyer did the original work for this commit with Ryan Wilson
addressing follow-ups.

This allows a single tmpfiles snippet with lines to symlink directories
from /usr/share/factory to be shared across many different configurations
while making sure symlinks only get created if the source actually exists.
The previous commit removed the UINT_MAX check for the fd array. Let's
now re-add one, but at a better place, and with a more useful limit. As
it turns out the kernel does not allow passing more than 253 fds at the
same time, hence use that as limit. And do so immediately before
calculating the control buffer size, so that we catch multiplication
overflows.
When an exec directory is shared between services, this allows one of the
service to be the producer of files, and the other the consumer, without
letting the consumer modify the shared files.
This will be especially useful in conjunction with id-mapped exec directories
so that fully sandboxed services can share directories in one direction, safely.
systemd-sysupdated is still unstable and we'd like to make breaking
changes to it even after the v257 release, so we document it as such and
disable building it by default in release builds. The distro can still
opt-in, and we still build it in developer mode so it has CI coverage
This commit introduces a build-time option to enable/disable sysupdated
separately from sysupdate. 'auto' translated to enabled by default in
developer builds.
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.
Fixes: #34634
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 2e8a581b9c and
edd3f4d9b7.
(Note, the commit messages of those commits are wrong, as
parse_boolean() supports on/off anyway.)
This makes use of the infra introduced in 229d4a9806 to indicate visually on each prompt that we are in superuser mode temporarily.
