Let's use oneshot services as we don't need long running services
for the tests we're doing. Let's also increase the sleeps a little
as the current values weren't sufficient when running the test locally
on my machine with mkosi.
If 3 lock messages get sent when going to sleep
then we can falsely assume we have woken up if we only assume we have at least two
so checking we have more than we did before sleeping addresses that issue.

Since we drop the coverage of built files from the final report anyway,
let's do it also when capturing both initial and real coverage to avoid
this error.
If we're not debugging tests, there's no point in persisting the journal,
so let's use the volatile journal storage mode in that case to avoid doing
unnecessary work.
We don't disable journal storage alltogether since various tests check
that stuff is written to the journal.
Required for integration tests to power off on PID 1 crashes. We
deprecate systemd.crash_reboot and related options by removing them
from the documentation but still parsing them.
OpenSUSE images seem to be unhappy with either how they are built
or what they are being asked to do.
The listed device-mapper failure is just one of the strange errors,
I have also seen it fail to propagate cgroup properties into new cgroups
that were previously guaranteed to exist.
This commit adds definitions to build the minimal_0 and minimal_1
images with mkosi and includes them into the system image. We also
move the building of the various app-xxx and similar images that are
extremely minimal into the tests itself by moving the related logic
from install_verity_minimal() into a new function
install_extension_images() in util.sh. Because the mkosi /usr is
read-only, we now place the extension images in /tmp instead of
/usr/share.

Otherwise we lose valuable logging from systemd-executor when things
go wrong since it can only log to the journal and not to the console
in these cases.
We cannot mark a test suite as excluded by default in meson. Instead,
let's require that SYSTEMD_INTEGRATION_TESTS=1 and skip any integration
test if it's not set. This is effectively the same as excluding it by
default. If the integration-test option is enabled, we'll set the
environment variable by default, just like we do with SYSTEMD_SLOW_TESTS
and the slow-tests meson option.
Also: rename Handover → Handoff. I think it makes it clearer that this
is not really about handing over any resources, but that the executor is
out off the game from that point on.
If an assert in systemd fails it can't shut down normally.
By default it freezes. For interactive runs we want the crash shell
to enable further debugging, but during test runs we want it to exit
without having to wait for the test timeout.
By deactivating the crash shell, enabling reboot, and configuring qemu
so that it shuts down instead of rebooting we can shut down instead.
Because by default UEFI will enroll keys and then reboot
we also have to set --qemu-firmware-variables=custom
so it doesn't need to auto-enroll.
Because mkosi has to handle not receiving an EXIT_STATUS notification
it falls back to the exit code of qemu, which in the case of reboot
would be 0, we also override the success exit status to 123
and check that we got that as an exit code from mkosi.
- Stop using logging module since the default output formatting is
pretty bad. Prefer print() for now.
- Log less, logging the full mkosi command line is rather verbose,
especially when it contains multi-line dropins.
- Streamline the journalctl command we output for debugging failed
tests.
- Don't force usage of the disk image format.
- Don't force running without unit tests.
- Don't force disabling RuntimeBuildSources.
- Update documentation to streamline the command for running a single
test and remove sudo as it's not required anymore.
- Improve the console output by having the test unit's output logged
to both the journal and the console.
- Disable journal console log forwarding as we have journal forwarding
as a better alternative.
- Delete existing journal file before running test.
- Delete journal files of succeeded tests to reduce disk usage.
- Rename system_mkosi target to just mkosi
- Pass in mkosi source directory explicitly to accomodate arbitrary
build directory locations.
- Add test interactive debugging if stdout is connected to a tty
- Stop explicitly using the 'system' image since it'll likely be
dropped soon.
- Only forward journal if we're not running in debugging mode.
- Stop using testsuite.target and instead just add the necessary
extras to the main testsuite unit via the credential dropin.
- Override type to idle so test output is not interleaved with
status output.
- Don't build mkosi target by default
- Always add the mkosi target if mkosi is found
- Remove dependency of the integration tests on the mkosi target
as otherwise the image is always built, even though we configure
it to not be built by default.
- Move mkosi output, cache and build directory into build/ so that
invocations from meson and regular invocations share the same
directories.
- Various aesthetic cleanups.
Currently, A large amount of unit test output is logged directly
to the console instead of to the per test log file as any subprocesses
executed by a test manager will detect that stderr is not connected
to the journal and log directly to /dev/console instead.
To solve this issue, let's make sure all tests are connected directly
to the journal by running them with systemd-run. We also simplify the
entire test script by getting rid of the custom queue and replicating
it with xargs instead. By using bash's function export feature, we can
make our run_test() function available to the bash subprocess spawned
by xargs.
Once a test is finished, we read its logs from the journal and put them
in the appropriate file if needed.
When starting a container with --user, the new uid will be resolved and switched to
only in the inner child, at the end of the setup, by spawning getent. But the
credentials are set up in the outer child, long before the user is resolvable,
and the directories/files are made only readable by root and read-only, which
means they cannot be changed later and made visible to the user.
When this particular combination is specified, it is obvious the caller wants
the single-process container to be able to use credentials, so make them world
readable only in that specific case.
Fixes https://github.com/systemd/systemd/issues/31794
The qemu seabios firmware disables serial console line wrapping. Let's
make sure we re-enable it again when we reset a terminal to some sane
defaults.
To avoid potentially blocking on writing to the terminal, we put it
in nonblocking mode and add a timeout of 50ms.
Enable the exec_fd logic for Type=notify* services too, and change it
to send a timestamp instead of a '1' byte. Record the timestamp in a
new ExecMainHandoverTimestamp property so that users can track accurately
when control is handed over from systemd to the service payload, so
that latency and startup performance can be trivially and accurately
tracked and attributed.
Resolve at attach/detach/inspect time, so that the image is pinned and requires
re-attaching on update, given files are extracted from it so just passing
img.v/ to RootImage= is not enough to get a portable image updated
I was bitten several times by testing things only with --root flag, so this
commit prepares the existing test cases to run on / too. This required the test
cases to clean up after themselves, thus I have put each test case in a
separate subshell and used traps to do the cleanups.
I needed to change the hierarchy used by the test extension to /opt, because
unmounting /usr often failed with EBUSY.
Let's rework the test a bit, namely:
- condense the code a bit
- drop unnecessary braces around variables
- drop unnecessary explanations around `touch` calls
- drop/rename functions to make the code more self-explanatory
- simplify cleanup a bit
- create R/O bind mounts directly (supported since util-linux 2.27)
Previously, 'udevadm control' only checked the number of the arguments.
So, if only `--timeout` is specified, it spuriously did nothing and succeeded.
This makes the command request at least one control command.
This requires a Coverity license, so the usefulness of the instructions
is somewhat limited, but at least I won't have to re-discover everything
from scratch when I need to debug something Coverity-related again in the
future.
The sender must be the first-hop router of the destination. Previously,
we only accepted Redirect messages whose sender is the current default
router with the highest priority.
See RFC 4861 section 8.1 for more details.
Fixes#31981.
Setting MTU announced in RA message to routes is problematic, as the
value may be larger than the device MTU (IFLA_MTU), and in such case the
route cannot be used.
These two properties are now set per-interface, and gracefully handled
such invalid cases. Hence not necessary to set them to each route.
Follow-up for #32195.
Unfortunately bfd30e8af6 is not enough and the test fails, that still
occasionally occur, don't provide enough information to see what's
wrong. Let's rework the test a little to improve this, namely:
- redirect curl's output into a temporary file instead of piping it
directly into the "check" expression; that way we can simply dump
the temporary file when the test fails, providing potentially
crucial information. We don't want to always dump everything to
stdout, as some of the tests request an entire system journal (note
that shell redirection instead of `curl -o file` is used
intentionally, so the output file is always nuked first)
- by dropping the pipes in curl commands we can re-enable pipefail
- also, split some very long commands to multiple lines to (slightly)
improve readability
Follow-up for bfd30e8af6.
The logs from TEST-69 still contain a lot of unnecessary shell
metacharacters, so to make the output more readable let's just set
TERM=dumb, instead of having to strip everything semi-manually. Also,
move the related --background= tweak to TEST-69, since it's relevant
only for that particular test.
Follow-up for 8d4bfd38ed.
The timeout on sd-resolved's side is 5-10s (UDP or TCP), but dig's
default timeout is 5s. Let's give sd-resolved enough time to timeout
before either giving up or checking if it served stale data on dig's
side.
Resolves: #31639
I collected a couple of fails in this particular test, but without any
output they're impossible to debug. Let's make this slightly less
annoying and let curl show an error (if any) even in silent mode.
This patch uncovers that curl has been (silently) complaining about not
being able to write to the output destination, because `grep -q`
short-circuits on the first match and doesn't bother reading the rest,
so replace `grep -q` with `grep ... >/dev/null` to force grep to always
read the whole thing from curl.
If we fail to mount the encrypted /var during boot we're left with
nothing to debug, so let's do the same thing we do for TEST-08-INITRD
and forward journal to the console.
s390x will define both s390x and s390, so exec-personality-s390.service is ran
in both cases but fails on s390x, as the personality returned is s390x.
Split the test and check specifically for s390x.
We stick to debug logging because in some cases network-generator
will fall back to trying another parsing function if one fails, so
if we return an error it's not necessarily a failure.
gcrypt is used only for journal sealing operations in libsystemd, so it
can be made into a dlopen dependency that is used only on demand. This
allows to reduce the footprint of libsystemd in the most common cases.
Keep systemd-pull and systemd-resolved with normal linking, as they are
executables, and usually built with OpenSSL support anyway.
Prep work for running the integration tests with meson, which requires
tests to exit with 77 to indicate they are skipped.
Note this only deals with the easy cases where there's only tests. The
hard ones where there's subtests of which only some are skipped are left
for another PR.
With plain QEMU on a saturated AWS region we might just barely miss the

Also, move the rest of container the setup for the user xattrs test into
the condition, since doing it without the actual test is pretty
pointless.
Same reason as the reload, reexec is disruptive and it requires the
same privileges, so if somebody wants to limit reloads, they'll also
want to limit reexecs, so use the same setting.
Previously, 'udevadm test' performs not only processing udev rules,
but made several destructive change on the system; updating udev
database, device node permission, devlinks, network interface
properties, and so on.
Similary, 'udevadm test-builtin' may perform something destructive,
especially by 'keyboard', 'kmod', and 'net_setup_link' builtins.
Let's make these commands and test executables not change device
configurations.
When listing images they are inspected one by one, so in case of a
portable with extensions they always resulted as not found.
Allow a partial match when listing, so that we can find the appropriate
unit that an image belongs to, and list the correct state as attached.
Currently app_1.0.raw is refused if it contains extension-release.d/extension-release.app,
which stops one from using versioned images without using the force flag to disable
the check. Relax it so that only the actual name, and not the version, is compared, like
it already happens in other places.
This fixes a race condition crash in homed that would happen in the
following sequence of events:
1. Client 1 takes a ref on the home area
2. Client 1 calls some method via dbus
3. Client 2 calls Release()
In homed, the Release() would check if a ref is still held (in this
case: yes it is) and returns an error. Except that is done through a
code-path that asserts that no operations are ongoing. In this case,
it's valid to have an ongoing operation, and so the assertion fails
causing homed to crash.
When sd-run connects to D-Bus rather than the private socket, it will
generate the transient unit name using the bus ID assigned by the D-Bus
broker/daemon. The issue is that this ID is only unique per D-Bus run,
if the broker/daemon restarts it starts again from 1, and it's a simple
incremental counter for each client.
So if a transient unit run-u6.service starts and fails, and it is not
collected (default on failure), and the system soft-reboots, any new
transient unit might conflict as the counter will restart:
Failed to start transient service unit: Unit run-u6.service was already loaded or has a fragment file.
Get the soft-reboot counter, and if it's greater than zero, append it
to the autogenerated unit name to avoid clashes.
losetup in util-linux 2.40 started reporting lost loop devices [0] and
it has an unfortunate side-effect where it reports lost devices even in
containers, which then makes the loop device check "falsely" pass [1].
Let's just check for /dev/loop-control explicitly to "work around" this.

Today listen file descriptors created by socket unit don't get passed to
commands in Exec{Start,Stop}{Pre,Post}= socket options.
This prevents ExecXYZ= commands from accessing the created socket FDs to do
any kind of system setup which involves the socket but is not covered by
existing socket unit options.
One concrete example is to insert a socket FD into a BPF map capable of
holding socket references, such as BPF sockmap/sockhash [1] or
reuseport_sockarray [2]. Or, similarly, send the file descriptor with
SCM_RIGHTS to another process, which has access to a BPF map for storing
sockets.
To unblock this use case, pass ListenXYZ= file descriptors to ExecXYZ=
commands as listen FDs [4]. As an exception, ExecStartPre= command does not
inherit any file descriptors because it gets invoked before the listen FDs
are created.
This new behavior can potentially break existing configurations. Commands
invoked from ExecXYZ= might not expect to inherit file descriptors through
sd_listen_fds protocol.
To prevent breakage, add a new socket unit parameter,
PassFileDescriptorsToExec=, to control whether ExecXYZ= programs inherit
listen FDs.

Drop connections and caches and reload config from files, to allow
for low-interruptions updates, and hook up to the usual SIGHUP and

settings are dropped and reloaded.

This patch fixes an issue where, when not specifiying either at least one
`SocketBindAllow` or `SocketBindDeny` rule, behavior for the bind syscall
filtering would be unexpected.
For example, when trying to bind to a port with only "SocketBindDeny=any"
given, the syscall would succeed:
> systemd-run -t -p "SocketBindDeny=any" nc -l 8080
Expected with this set of rules (also in accordance with the documentation)
would be an Operation not permitted error.
This behavior occurs because a default initialized socket_bind_rule struct
matches what "any" represents. When creating the bpf list all elements get
default initialized, as such represeting "any". Seemingly it is necressarry
to set the size of the map to at least one, as such if no allow rule is
given default initialization and minimal map size cause one any allow rule
to be in the map, causing the behavior observed above.
This patch solves this by introducing a new "match nothing" magic stored in
the rule's address family and setting such a rule as the first one if no
rule is given, making sure that default initialized rule structs are never
used.
Resolves#30556
Rate limiting authentication attempts in the test can cause somewhat
sporadic test failures: adding a test case might suddenly cause future
test cases to fail because of too many authentication attempts too
quickly
We're not trying to test the rate-limiting, we're trying to test the
functionality of homed. So we effectively disable rate-limiting on all
the home areas we create
This makes it possible to update a home record (and blob directory) of a
home area that's either completely absent (i.e. on a USB stick that's
unplugged) or just inaccessible due to lack of authentication
This bypasses authentication (i.e. user_record_authenticate) if the
volume key was loaded from the keyring and no secret section is
provided.
This also changes Update() and Resize() to always try and load the
volume key from the keyring. This makes the secret section optional for
these methods while still letting them function (as long as the home
area is active)
Private images are not reused, they are unique to tests, so delete them
as they take a lot of disk space, and we are starting to run in /var/tmp
space issues on the Ubuntu CI
Naming is always a matter of preference, and the old name would certainly work,
but I think the new one has the following advantages:
- A verb is better than a noun.
- The name more similar to "the competition", i.e. 'sudo', 'pkexec', 'runas',
'doas', which generally include an action verb.
- The connection between 'systemd-run' and 'run0' is more obvious.
There has been no release yet with the old name, so we can rename without
caring for backwards compatibility.
Currently, if a unit file is enabled from outside of the search path,
and that unit has an alias, then the symlink ends up pointing outside of
the search path too. For example:
$ cat /tmp/a.service
[Service]
ExecStart=sleep infinity
[Install]
Alias=b.service
WantedBy=multi-user.target
$ systemctl enable /tmp/a.service
Created symlink /etc/systemd/system/a.service → /tmp/a.service.
Created symlink /etc/systemd/system/b.service → /tmp/a.service.
Created symlink /etc/systemd/system/multi-user.target.wants/a.service → /tmp/a.service.
This then means the alias is treated as a separate unit:
$ systemctl start a.service
$ sudo systemctl status a
● a.service
Loaded: loaded (/etc/systemd/system/a.service; enabled; preset: enabled)
Active: active (running) since Fri 2024-03-15 15:17:49 EDT; 9s ago
Main PID: 769593 (sleep)
Tasks: 1 (limit: 18898)
Memory: 220.0K
CPU: 5ms
CGroup: /system.slice/a.service
└─769593 sleep infinity

$ sudo systemctl status b
○ b.service
Loaded: loaded (/etc/systemd/system/b.service; alias)
Active: inactive (dead)
To fix this, make sure the alias uses a target that is inside the search
path. Since the unit file itself is outside of the search path, a
symlink inside the search path will have been created already. Hence,
just point the alias symlink to that recently created symlink.
This also drop the support of /run/systemd/netif/persistent-storage-ready,
as the file is anyway removed when networkd is stopped.
Let's use $SYSTEMD_NETWORK_PERSISTENT_STORAGE_READY=1 instead on testing.
If both $ARTIFACT_DIRECTORY and $SPLIT_TEST_LOGS are set, split the
output from each test into a separate log file, so we don't have to load
one ginormous log file when checking the results.
In automated QA environments there may be tests that are known to fail,
and being able to skip them is useful to remove known failures from the
test log.

dig question with DNSSEC on will now be proxied upstream, i.e. to the
test knot server. This leads to different results, but the result isn't
tha tinteresting since we don't want to test knot, but resolved. Hence
comment this test.
There seems to be something wrong with the test though, as the upstream
server refused recursion, but if so it is not suitable as an upstream
server really, as resolved can only be client to a recursive resolver.
sulogin from the latest util-linux started falling back to vt102 instead
of linux, which makes screen sad (because we install only the linux
terminfo into the test image) and expect trips over the unexpected

avoid this.

Otherwise, even if the interface is available, the requested config may
not be applied to the interface yet.
This also merges multiple tests for RPS setting. Hopefully the
performance of the test is improved.
