In https://github.com/systemd/systemd/pull/41688 we merged metrics
and facts for systemd-report. However while some metric sources
are enabled by default (like `io.systemd.{Manager,Network}`) the
`io.systemd.Basic` service is not enabled by default.
This commit changes this and enables it by default.
We could also enable the systemd-report-cgroup.socket but that sends
a lot more data not sure that is a good default.
The test occasionally fails on GHA CI when formatting with xxhash64

The test is flaky under sanitizers as the timeouts seem to be too short,
bump them like we do in other tests to try and make it more robust when
running with sanitizers
The socket's SubState transitions from 'running' to 'listening' shortly
after the triggered service becomes inactive, so the assert can race and
observe the stale 'running' state:

Poll for 30s instead of directly asserting to try and make it more robust
The restart-trigger subtest occasionally fails on CI with:
+ assert_eq 0 1
FAIL: expected: '1' actual: '0'
even though the timer fires correctly and the echo message is in fact
written to the journal. The failure happens because the test relies on
`journalctl --unit=$UNIT_NAME` to find the message, and that filter is
based on the cgroup journald looks up for the writer PID at the time
the stdout message is received.
For very short-lived processes spawned via systemd-executor (like
`echo`), that lookup is racy: the writer's `/proc/$PID/cgroup` can
still resolve to `/init.scope` (systemd-executor's own cgroup) rather
than the service's cgroup, so the message ends up attributed to
`init.scope` and `--unit=` filtering misses it.

FAIL: expected: '1' actual: '0'
For comparison, in a passing local run the same message is attributed
correctly to the service unit (_SYSTEMD_UNIT=timer-restart-24147.service),
so `--unit=` matches.
Work around the underlying journald race in the test by setting an
explicit `SyslogIdentifier=` on the service and matching with `-t` plus
the unique grep pattern: `SyslogIdentifier` is carried over the stdout
stream protocol and is not affected by the cgroup lookup race.

The test occasionally fails because lsns returns empty output for the
transient unit, even though the process is running. e.g.:
```

The basic idea is that --chain should stop option parsing. But
previously this didn't work, so --chain could be specified anywhere
in the command line. To maintain with compatibility with that,
allow --chain to be specified anywhere until the first positional
arg or option in the command string. This allows options to be passed
in the expected fashion:
userdbctl --chain ssh-authorized-keys user cmd --opt1 --opt2
userdbctl --chain ssh-authorized-keys user -- cmd --opt1 --opt2
but also allows the invocations which worked previously:
userdbctl ssh-authorized-keys user --chain cmd
userdbctl ssh-authorized-keys user cmd --chain
Fixes 8072a7e6a9.
The error messages are extended a bit. "binary path" is misleading:
we support all kinds of executables, not only compiled programs.

The test used `timeout 30 bash -c "journalctl -b -u $unit -f | grep -m1 ..."`
to wait for systemd-networkd-wait-online to log that no DNS server is
accessible. The expected message is actually emitted ~1s after the unit
starts, but `grep -m1` exiting doesn't tear down `journalctl -f`: journalctl
only notices the closed pipe on its next write, which may never happen for
an otherwise idle unit. The pipeline therefore hangs until the 30s timeout
fires, eventually causing the test to fail.
Replace the follow+pipe with a polling `journalctl --grep` loop, which
exits cleanly as soon as the message lands in the journal.

We removed the concept of facts, so we need to update the existing
io.systemd.Basic facts provider to metrics. This commit does just
that. Its mostly mechanical.
This also means that facts.{c,h} and varlink-io.systemd.Facts.{c,h}
are gone now.
Two new verbs are added: "generate" and "upload". The first one just
creates a "report", i.e. puts the metrics into a structured JSON object
that in the future is intended to carry additional data like a
signature:
$ build/systemd-report generate io.systemd.Manager.UnitsTotal
{
"mediaType" : "application/vnd.io.systemd.report",
"timestamp" : "Tue 2026-04-28 22:30:09 UTC",
"metrics" : [
{
"name" : "io.systemd.Manager.UnitsTotal",
"value" : 520
}
]
}
The second verb can be used to upload or otherwise process the report.
It builds on the code added in 0a8560eed8.
In /run/systemd/metrics-upload/ we expect a set of sockets. We'll call
out to each one of them. This allows the data to be processed in custom
ways, incl. writing to storage or sending over the network.
Each socket must provide a single interface:
io.systemd.Metrics.Upload {"report":$data}
This test is sometimes flaky under sanitizers, and it does repeated
calls with the same parameters to run through different greps, and
the second one sometimes fails.
Store the result and grep it twice instead to try and reduce
flakiness.

A segfault is observed when both key_file and tpm2-device are
simultaneously passed to systemd-cryptsetup, e.g.:

The dditest block calls systemd-repart with Encrypt=tpm2 but without
--tpm2-public-key-pcrs=. Since systemd-stub drops
/run/systemd/tpm2-pcr-public-key.pem when booting from a signed UKI
systemd-repart auto-loads it and enrolls a signed PCR policy, and
then systemd-cryptsetup tpm2-device=auto has no matching signature file,
so unlock fails.
--tpm2-public-key= is not enough as the default kicks in then.

mdadm --zero-superblock only wipes the MD metadata on the underlying
disks, not the LVM PV header that lives in the array data area. When
the VM is restarted and the test re-creates the array with the same
UUID, /dev/md127 exposes the old data including the LVM PV header, so
udev's 69-lvm.rules auto-triggers lvm-activate-mdlvm_vg.service which
races with the test's own pvcreate for exclusive access on /dev/md127.
Wipe the LVM signature off the MD device (and the underlying disks as
a belt-and-braces measure) to avoid the race on re-run, fixing failures
when the VM is rebooted instead of shut down.

With 99999 possible unit names collisions are rare but not impossible,
so every now and then a CI run fails.
Have write_to_journal() set a global SERVICE_NAME variable instead and
call it directly so SERVICE_COUNTER actually goes up through the test.
When key_file is passed along with tpm2-device= to systemd-cryptsetup, the
logic is to try the blob as a TPM blob first, and then fall back to trying the
file as a regular key file. Check that this fallback works.
When qemu reboots instead of shutting down after the last iteration,
the profile is already set to profile2 but the /root/encrypted.raw is
gone so the test fails. Reset the default boot entry at the end of the
test to make it robust against reruns.
Fixes https://github.com/systemd/systemd/issues/39553
The test leaves a lot of state around, and when the test is re-run,
for example due to the qemu bug that makes a VM reboot instead of
shutting down, it fails.
Do more cleanups in the traps.

The new "varlinkctl --more StartTransient" subtest pipes a JSON-SEQ
stream of multiple records into "jq --seq -e ...". CentOS 9
ships jq 1.6, where -e only inspects the last input record's output:
when the trailing record (the final reply) doesn't match the
"select()" filter, jq exits non-zero even though earlier records
match, so the test fails.
Use --slurp which collapses the records into an array first and
returns a single bool.

Introduce a counter that tracks how many configuration reloads have
been successfully completed by the manager. The increment lives in
manager_reload() right after the "point of no return", so failed
reload attempts that bail out earlier (e.g. during serialization)
do not bump the counter.
It is accessible as a new ReloadCount property to
org.freedesktop.systemd1.Manager (D-Bus) and ReloadCount to
io.systemd.Manager.Describe (Varlink).
Also add an integration test for ReloadCount
that verifies that the new ReloadCount property increments by one per
daemon-reload, accumulates correctly across multiple reloads, and that
D-Bus and Varlink return identical values. Also tests that the counter
reset after a reexec.

This also fixes some issues regarding "root" directory handling.
In one context we'd resolve a directory claiming it was a "root", but it
wasn't.

Extend io.systemd.CGroup.CpuUsage from a single per-unit nanosecond
counter to three rows distinguished by a "type" field of "total",
"user", or "system". The values come from cpu.stat's usage_usec,
user_usec and system_usec keys, read in a single keyed-attribute
fetch and cached on each CGroupInfo so each scrape only opens
cpu.stat once per cgroup.
This gets rid of the duality in the cmdline interface and various
APIs. The general plan is collect both "facts" and "metrics" in a
single list. We have various producers which respond on the
io.systemd.Facts endpoint. Those will need to be adjusted to respond
to io.systemd.Metrics.
Cmdline interface:
'metrics' (unchanged)
'describe-metrics' → 'describe'
'facts' → merged into 'metrics'
'describe-facts' → merged into 'describe'
VM-only test that exercises both shipped providers through storagectl:
verifies the well-known sockets exist, lists providers/volumes/
templates, creates and acquires volumes from each template
(sparse-file, allocated-file, directory, subvolume), attaches a loop
device to cover the block provider, and exercises the mount.storage
helper.
This commit adds a simple version of io.systemd.Unit.StartTransient
for varlink. It is similar to the dbus version, but there is a key
difference:
1. Instead of building the unit from key/value properties it
takes a structured json object "UnitContext" with a "Service" field
inside.
It is also only implementing a minimal set of what can be done with a
service.
2. No aux units (for now)
3. When called with --more the varlink socket can notify about
state changes depending on the notify{Job,Unit}Changes parameter
This aligns to the json objects/format from
https://github.com/systemd/systemd/pull/39391
and to show how the format can be shared it adds a new
(minimal) `ServiceContext` that is now part of
`io.systemd.Unit.List()`.
The sanitizer job was FUBAR on Fedora Rawhide (and RHEL 10 to some
extent) due to several changes:
- latest LLVM (v22) introduced a change that occasionally generates a
false-positive warning when running with sanitizers
- several tools had to be "ASan-wrapped" because:
- util-linux started linking against libsystemd which propagated to
other tools depending on its shared libraries (like libmount)
- libssh started depending on libfido2, which depends on libudev; this
then translated to an interesting depedency chain where tpm2 utils got a
dependency on libudev through libcurl -> libssh -> libfido2
- polkit added MemoryMax= to its service file, which is incompatible
with ASan-runs (at least with the current limits)
See the commits for more detailed descriptions.
Also, one note: the santizer job is currently still FUBAR on Fedora
Rawhide (or, more specifically, the TEST-50-DISSECT and TEST-58-REPART),
because mkfs.erofs also gained a dependency on libudev (through libcurl,
see above), but the wrapping currently doesn't work as it also depends
on libqpl which is linked with libtsan (which is incompatible with other
sanitizers). This is currently tracked in
https://bugzilla.redhat.com/show_bug.cgi?id=2461146
LLVM 22 introduced an additional check [0] for ptrace() syscall when
invoking sanitizers [0] which currently produces a false-positive
warning when running some of our units under sanitizers:
[ 47.524680] systemd-timedated[740]: ==740==WARNING: ptrace appears to be blocked (is seccomp enabled?). LeakSanitizer may hang.
[ 47.524680] systemd-timedated[740]: ==740==Child exited with signal 15.
...
[ 1555.734223] systemd-oomd[93]: ==93==WARNING: ptrace appears to be blocked (is seccomp enabled?). LeakSanitizer may hang.
[ 1555.734223] systemd-oomd[93]: ==93==Child exited with signal 15.
...
It is a false positive because we disable the seccomp filters
system-wide for our units in the sanitizer jobs.
Now, from what I've seen so far this happens only in
Type=notify(-reload) units that also utilize bus_event_loop_with_idle().
This, combined with the fact that the ptrace()-check child process from
[0] checks only if the child process was killed by _any_ signal, means
that if the systemd unit exits on its own after becoming idle and then
something sends it SIGTERM (either via explicit `systemctl stop` or
during system shutdown), this SIGTERM might hit the ptrace()-check child
process from the sanitizer handler (as we also send the signal to all
processes in the target cgroup), which the parent process then
mistakenly evaluates as a blocked ptrace() syscall, even though the
check process wasn't killed by SIGSYS.
I filed this as [1] to the LLVM project, but let's also temporarily
ignore the warning in the sanitizer report processing, as it currently
causes annoying test fails.
