Since the library is dlopen()ed by libpthread and required during
pthread_exit()/pthread_cancel(), let's install it explicitly if available to
avoid unexpected fails in tests. This also consolidates all related
workarounds for this library across the test scripts.
Bash allows only one handler per signal, so let's overcome this
limitation by having one dedicated EXIT signal which runs all registered
handlers from all over the place.
so we can run TEST-24 under sanitizers as well.
Also, when at it, use the 'named-fields' sfdisk format to make the code
a bit more descriptive without needing a manual.
- use test_append_files() to install additional commands
- drop use of expect
- include assert.sh and use assertions at several places
- use timeout command at several places
- always use logind-test-user
- etc
since we delete the guest journals as part of the save_journal() step in
check_result_common(), making journal inaccessible from the custom check
hooks.
Let's detect & wrap binaries which are linked against systemd DSOs and
we're running under ASan, since otherwise running such binaries ends
with:
```
==633==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.
```
Since we unset $LD_PRELOAD in the testsuite-* units (due to another
issue), let's store the path to the ASan DSO in another env variable, so
we can easily access it in the testsuite scripts when needed.
If rngd is included in the host initrd, QEMU guests need at least one source of
entropy otherwise rngd will refuse to start. Hence this patch enables the
virtio RNG device in QEMU guests (exposed as a HW RNG device available at
/dev/hwrng).
As a safety measure, the patch limits the data sent to the guest to 1KB per
second in order to not let the guest starve the host entropy.
We used both "qemu" and "QEMU", let's use the lower-case version everywhere
since it's also the name of the binary and the version that people are
most familiar with.
The stuff under test/ is not only for the integeration tests, but also
for various other test-related stuff, so adjust the docs a bit.
Since c6552ad we now try to collect coverage even in situations where
it's basically impossible (like in test-mount-util where the whole / is
mounted as read-only). As dealing with this is not worth the trouble,
let's ignore the missing coverage errors thrown by gcov in such cases.
Add tests for enrolling and unlocking. Various cases are tested:
- Default PCR 7 policy w/o PIN, good and bad cases (wrong PCR)
- PCR 7 + PIN policy, good and bad cases (wrong PCR, wrong PIN)
- Non-default PCR 0+7 policy w/o PIN, good and bad cases (wrong PCR 0)
v2: rename test, fix tss2 library installation, fix CI failures
v3: fix ppc64, load module
IIUC, pipefail doesn't matter for a sequence of commands joined with &&, and we
don't have any pipes. And such a failing expression also does not trigger an
exit, so the set +e/set -e were noops.
It should make it easier to figure out what exactly services do there.
For example, with SYSTEMD_LOG_LEVEL=debug userdbd (v249) prints
```
varlink-5: New incoming message: {"method":"io.systemd.UserDatabase.GetUserRecord","parameters":{}}
```
before it crashes and systemd-resolved prints
```
varlink-21: New incoming message: {"method":"io.systemd.Resolve.ResolveAddress","parameters":{"address":[127,0,0,1],"flags":0,"ifindex":1000000,"family":0}}
```
and those messages are helpful (especially when scripts causing them
aren't clever enough to keep track of random stuff they send to systemd
:-))
otherwise units using `DynamicUser=yes` won't be able to write the
coverage stats (currently affecting TEST-20-MAINPIDGAMES).
`DynamicUser=yes` implies `ProtectSystem=strict` and
`ProtectHome=read-only` and can't be overridden hence we need to
utilize `ReadWritePaths=` to work around that.
If the test logs contain lines like:
```
...systemd-resolved[735885]: profiling:/systemd-meson-build/src/shared/libsystemd-shared-250.a.p/base-filesystem.c.gcda:Cannot open
```
it means we're possibly missing some coverage since gcov can't write the stats,
usually due to the sandbox being too restrictive (e.g. ProtectSystem=yes,
ProtectHome=yes) or the $BUILD_DIR being inaccessible to non-root users.
