With 1df4b21abd we started to default to
enrolling into the LUKS device backing the root fs if none was specified
(and no wipe operation is used). This changes to look for /var/ instead.
On most systems /var/ is going to be on the root fs, hence this change
is with little effect.
However, on systems where / and /var/ is separate it makes more sense to
default to /var/ because that's where the persistent and variable data
is placed (i.e. where LUKS should be used) while / doesn't really have
to be variable, could as well be immutable, or ephemeral. Hence /var/
should be a safer default.
Or to say this differently: I think it makes sense to support systems
with /var/ being on / well. I also think it makes sense to support
systems with them being separate, and /var/ being variable and
persistent. But any other kind of system I find much less interesting to
support, and in that case people should just specify the device name.
Also, while we are at it, tighten the checks a bit, insist on a dm-crypt
+ LUKS superblock before continuing.
And finally, let's print a short message indicating the device we
operate on.
When we fail to add an entry to a journal file, typically when the file
is full or corrupted, it is not necessary to rotate other journal files.
Not only that's unnecessary, rotating all journal files allows
unprivileged users to wipe system or other user's journals by writing
many journal entries to their own user journal file.
Let's rotate all journal files only when
- it is really requested by a privileged user (e.g. by journalctl --rotate), or
- the system time jumps backwards.
And, otherwise rotate only the journal file we are currently writing.
Doing this in reset_terminal_fd() is a bit too invasive, see
https://github.com/systemd/systemd/pull/32406#issuecomment-2070923583.
Let's only do this for /dev/console so that we work around weird firmwares
disabling line-wrapping, but avoid messing too much with other things.
While we're at it, let's handle more than just line wrapping, and do a
more general reset of stuff to get the terminal into a sane state.
This is a follow-up for e50bfc89ce
In that commit, we made Freeze/Thaw work with unrealized cgroups.
However, the unit was left in a strange state: it would be frozen by the
kernel but systemd would be unaware, and it remained possible to try and
realize the cgroup while the unit is supposed to be frozen. This commit
fixes the state tracking and prevents cgroups from being realized when
the unit is frozen.
We do the image build and run the tests in a btrfs loopback so we
can make use of btrfs subvolumes and COW to keep the disk space
requirements to a minimum and speed up the ephemeral copies we make
of the image to run the tests.
We also switch to building debug packages and publishing the built
packages as artifacts.
- 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.
Building debug packages on ubuntu requires the "debug" option to be
specified explicitly. Debug packages on Ubuntu have the .ddeb extension,
so let's make sure we handle that by copying the .ddeb packages in the
build script as well.
-ffile-prefix-map= implies -fmacro-prefix-map= which is incompatible
with our definition of PROJECT_FILE.
See https://github.com/systemd/systemd/issues/32417.
-fdebug-prefix-map= only affects debuginfo without affecting macros.
isc-dhcp-server does not ship units, only sysv scripts, so the mkosi
presets that disable it have no effect. The generated unit is started on
each boot and fails, causing delays and noise.
Mask it so that the generated unit is overridden. It is installed only
to bring in binaries used by the networkd tests anyway.
This file makes clear the interface shall be owned by networkd.
This does what 658169e6d3 did for nspawn's
regular devices for the devices defined through
8aee931e7a too.
After db26d8025e,
kernel-install takes config files under /run/
and /usr/local/lib/ into account too. The same
should apply to ukify.
Note that ukify when invoked alone searches under
/run/systemd/, /etc/systemd/, /usr/local/lib/systemd/,
and /usr/lib/systemd/, respectively, which is against
our usual order...
The log files defined using file:, append: or truncate: inherit the owner and other privileges from the effective user running systemd.
The log files are NOT created using the "User", "Group" or "UMask" defined in the service.
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.
