Specifying the test number manually is tedious and prone to errors (as
recently proven). Since we have all the necessary data to work out the
test number, let's do it automagically.
We have to invoke the tests as superuser, and not being able to read
the journal as the invoking user is annoying. I don't think there are
any security considerations here, since the invoking user can already
put arbitrary code in the Makefile and test scripts which get executed
with root privileges.
The logic to query test state was rather complex. I don't quite grok the point
of ret=$((ret+1))… But afaics, the precise result was always ignored by the
caller anyway.
This code was partially broken, since the firmware directory was
undefined. Also, some of the parts were a dead code, since they relied
on code from the original dracut test suite.
`command -v <bin> | grep ...` can under certain conditions cause the
`command` to exit with SIGPIPE, which in combination with `set -o
pipefail` means that the tests sometimes randomly die during setup.
Let's avoid using pipes in such cases.
This breaks some existing loops which previously ignored if the piped
program exited with EC >0. Rewrite them to mitigate this (and also make
them more robust in some cases).
When trying to calculate the next firing of 'Sun *-*-* 01:00:00', we'd fall
into an infinite loop, because mktime() moves us "backwards":
Before this patch:
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
tm_within_bounds: good=0 2021-03-29 01:00:00 → 2021-03-29 00:00:00
...
We rely on mktime() normalizing the time. The man page does not say that it'll
move the time forward, but our algorithm relies on this. So let's catch this
case explicitly.
With this patch:

otherwise udev complains about the file being world-writable:
systemd-udevd[228]: Configuration file /etc/udev/rules.d/00-set-LD_PRELOAD.rules is marked world-writable. Please remove world writability permission bits. Proceeding anyway.
Fixes: systemd/systemd-centos-ci#354
This test would normally get stuck when trying to mount the verity image
due to:
systemd-udevd[299]: dm-0: '/usr/sbin/dmsetup udevflags 6293812'(err) '==371==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.'
systemd-udevd[299]: dm-0: Process '/usr/sbin/dmsetup udevflags 6293812' failed with exit code 1
...
systemd-udevd[299]: dm-0: '/usr/sbin/dmsetup udevcomplete 6293812'(err) '==372==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.'
systemd-udevd[299]: dm-0: Process '/usr/sbin/dmsetup udevcomplete 6293812' failed with exit code 1.
systemd-udevd[299]: dm-0: Command "/usr/sbin/dmsetup udevcomplete 6293812" returned 1 (error), ignoring.
so let's add a simple udev rule which sets $LD_PRELOAD for the block
subsystem.
Also, install the ASan library along with necessary dependencies into
the verity minimal image, to get rid of the annoying (yet harmless)
errors about missing library from $LD_LIBRARY.
When running integration tests under sanitizers D-Bus fails to
shutdown cleanly, causing unnecessary noise in the logs:
```
dbus-daemon[272]: ==272==LeakSanitizer has encountered a fatal error.
dbus-daemon[272]: ==272==HINT: For debugging, try setting environment variable LSAN_OPTIONS=verbosity=1:log_threads=1
dbus-daemon[272]: ==272==HINT: LeakSanitizer does not work under ptrace (strace, gdb, etc)
```
Since we're not "sanitizing" D-Bus anyway let's disable LSan's at_exit
check for the dbus.service to get rid of this error.
When a subshell is used ('make' or 'make all') the LOOPDEV environment
variable, which is used to store the opened loop device, is lost.
So the cleanup on trap/exit doesn't do anything, and the loop
device used to mount the test image is left around.
Avoid using a subshell to fix the issue.
The source package in the apt cache might be older than the
packaging from salsa.debian.org/systemd-team/systemd so it might not
list all the current binary packages.
This is currently the case for systemd-timesyncd, so TEST-30 fails.
Simply grep the control file rather than using apt-cache when iterating
over the packages contents.
Binaries on the latest Arch Linux use `call` instructions instead of
`callq`, which breaks the ASan detection and eventually the image
building process (due to insufficient space).
There may be situations where a cgroup should be protected from killing
or deprioritized as a candidate. In FB oomd xattrs are used to bias oomd
away from supervisor cgroups and towards worker cgroups in container
tasks. On desktops this can be used to protect important units with
unpredictable resource consumption.
The patch allows systemd-oomd to understand 2 xattrs:
"user.oomd_avoid" and "user.oomd_omit". If systemd-oomd sees these
xattrs set to 1 on a candidate cgroup (i.e. while attempting to kill something)
AND the cgroup is owned by root, it will either deprioritize the cgroup as
a candidate (avoid) or remove it completely as a candidate (omit).
Usage is restricted to root owned cgroups to prevent situations where an
unprivileged user can set their own cgroups lower in the kill priority than
another user's (and prevent them from omitting their units from
systemd-oomd killing).
Add NO_BUILD var to allow testing with no local build, by installing
local systemd files into the image.
This only works for debian-like distros currently, that use the
tools 'apt' and 'dpkg' for package management.
The $BUILD_DIR is only used in test-functions, and doesn't need to
be specified in any other scripts. Additionally, to be able to allow
the integration test suite to be run against locally installed binaries,
instead of built binaries, moving BUILD_DIR logic completely into
test-functions allows later patches to be simpler.
Building custom images for each test takes a lot of time.
Build the default one, and if the test needs incompatible changes
just copy it and extend it instead.
This reverts commit 73484ecff90f2cc235d827c0e955999bffe64dd0.
3976f372ae91e1cbe5ff9873aadfc2c43400452e moved libudev.so to be built in the
main directory, so this addition to $LD_LIBRARY_PATH is now obsolete.
After that commit, we build the following shared libraries:
build/libnss_myhostname.so.2
build/libnss_mymachines.so.2
build/libnss_resolve.so.2
build/libnss_systemd.so.2
build/libsystemd.so.0.30.0
build/libudev.so.1.7.0
build/pam_systemd.so
build/pam_systemd_home.so
build/src/boot/efi/stub.so
build/src/boot/efi/systemd_boot.so
build/src/shared/libsystemd-shared-247.so
EFI stubs don't matter, and libsystemd-shared-nnn.so is loaded through rpath,
and is doesn't need to and shouldn't be in $LD_LIBRARY_PATH. In effect, we only
ever need to add the main build directory to the search path.
Not all optional libraries might be available on developers machines,
so log and skip.
Also some pkg-config files are broken (eg: tss2 on Debian Stable) so
skip if the required variables are missing, and improve logs.
By default the test suite prefers qemu, and uses nspawn only if
a test specifically says it doesn't support qemu.
Add a variable to allow flipping the default, and run as many
tests under nspawn as possible.
Allows to split the test run in two parts. Most tests can run under
nspawn which is much faster, and they can be ran in one chunk with
TEST_NO_QEMU=1. The qemu-only tests, which are just a handful, can
be ran in another chunk with TEST_QEMU_ONLY=1.
Allows autopkgtest to be split in two parts.
The image build function greps for ExecStart lines in unit files, but some
of them (eg: systemd-firstboot) do not use a full path.
It then falls back to 'type -P' but that only works if you have the binary
installed. For optional binaries like systemd-firstboot, the installation
can then fail.
Manually check if the binary already exists in /[usr/][s]bin.
Usually on Debian ROOTLIBDIR is /lib/<arch triplet>, which is not the right place.
Use pkg-config since we define it, and then fallback to /usr/lib/systemd/user which is
the canonical location.
On both Debian&friends and Fedora dbus/dbus-broker install the user socket/service
under /usr/lib/systemd/user, not /lib/systemd/systemd/user.
I suspect the original version of the regex was written on a system,
which prints both the QEMU version and the QEMU package version in the
--version output, like Fedora:
$ /bin/qemu-system-x86_64 --version
QEMU emulator version 4.2.1 (qemu-4.2.1-1.fc32)
Copyright (c) 2003-2019 Fabrice Bellard and the QEMU Project developers
However, Arch Linux prints only the QEMU version:
$ /bin/qemu-system-x86_64 --version
QEMU emulator version 5.2.0
Copyright (c) 2003-2020 Fabrice Bellard and the QEMU Project developers
This causes the awk regex to not match the version string, since there's
no whitespace after it, causing the version check to fail (as well as the
TEST-36-NUMAPOLICY) as well.
Follow-up for 43b49470d1f2808555c07f64cd0a1529b7ddd559.
Upgrading to qemu 5.2 breaks TEST-36-NUMAPOLICY like:
qemu-system-x86_64: total memory for NUMA nodes (0x0) should
equal RAM size (0x20000000)
Use the new (as in >=2014) form of memdev in test 36:
-object memory-backend-ram,id=mem0,size=512M -numa node,memdev=mem0,nodeid=0
Since some target systems are as old as qemu 1.5.3 (CentOS7) but the new
kind to specify was added in qemu 2.1 this needs to add version parsing and
add the argument only when qemu is >=5.2.
Fixes#17986.

The systemd-user file has been moved from /etc/pam.d into /usr/lib/pam.d,
so test-functions needs to copy it from /usr/lib/pam.d instead.
This will copy it from either location.
When invoking "ldd" to find dependency libraries we already set
$LD_LIBRARY_PATH to point to our own build tree, so that our libraries
are checked, not the host libraries. This is not sufficient howeever, as
libudev is built in a subdir. Add that, too.
We have four legal cases:
1. /usr/lib/os-release exists and /etc/os-release is a symlink to it
2. both exist but /etc/os-release is not a symlink to /usr/lib/os-release
3. only /usr/lib/os-release exists
4. only /etc/os-release exists
The generic setup code in test-functions and create-busybox-image didn't handle
case 3.
The test-specific code in TEST-50 didn't handle 2 (because the general setup
code would only install /etc/os-release in the image and
grep -f /usr/lib/os-release would not work) and 4 (same reason) and would fail
in case 3 in generic setup.
