21e4e3e06f basic/ellipsize: do not assume the string is NUL-terminated when length is given
oss-fuzz flags this as:

I didn't reproduce the issue, but this looks like an obvious error: the length

C-strings.

3edc0c590d test: disable QEMU based testing for TEST-16-EXTEND-TIMEOUT
The test is heavily dependent on timeouts, and if we are run in
potentially very slow QEMU instances there's a good chance we'll miss
some which we normally wouldn't miss. Hence, let's test this one in
nspawn only. Given that the test is purely in service management it
shouldn't matter whether it runs in nspawn or qemu, hence keep running
it in nspawn, but don't bother with qemu.

Similar, do this for TEST-03-JOBS, too, which operates with relatively
short sleep times internally.

Fixes: #9123

cc4338e435 tests: tighten check for TEST-06-SELINUX dependencies a bit
As it turns out /usr/share/selinux/devel/ is now included in more RPMs
than just selinux-policy-devel (specifically container-selinux, which is
pulled in by various container related RPMs). Let's hence tighten the
dependency check a bit and look for systemd's .if file, which is what we
actually care about.

9924aef690 test-ellipsize: add tests for ellipsize_mem, fix bugs
First, ellipsize() and ellipsize_mem() should not read past the input
buffer. Those functions take an explicit length for the input data, so they
should not assume that the buffer is terminated by a nul.

Second, ellipsization was off in various cases where wide on multi-byte
characters were used.

We had some basic test for ellipsize(), but apparently it wasn't enough to
catch more serious cases.

Should fix https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=8686.

03d1319b12 shared/logs-show: be more careful before using a _SOURCE_REALTIME_TIMESTAMP entry
journalctl -o short would display those entries, but journalctl -o short-full
would refuse. If the entry is bad, just fall back to the receive-side realtime
timestamp like we would if it was completely missing.

324d6aa926 shared/logs-show: fix mixup between length-based memory duplication and string operations
We'd look for a '=' separator using memchr, i.e. ignoring any nul bytes in the
string, but then do a strndup, which would terminate on any nul byte, and then
again do a memcmp, which would access memory past the chunk allocated by strndup.

Of course, we probably shouldn't allow keys with nul bytes in them. But we
currently do, so there might be journal files like that out there. So let's fix
the journal-reading code first.

e743ce7053 journal-remote: when an entry is rejected with -EBADMSG, do not rotate the journal file
Something is wrong with the entry (probably a missing timestamp), so no point
in rotating. But suppress the error in process_source(), so that the processing
of the data stream continues.

Also, just return 0 from writer_write() on success, the only caller doesn't
care.

b294e5943f core: introduce specifiers for /tmp and /var/tmp
This corresponds nicely with the specifiers we already pass for
/var/lib, /var/cache, /run and so on.

This is particular useful to update the test-path service files to
operate without guessable files, thus allowing multiple parallel
test-path invocations to pass without issues (the idea is to set $TMPDIR
early on in the test to some private directory, and then only use the
new %T or %V specifier to refer to it).

Yes, the output is sometimes annyoing, but /dev/null is not the right
place...

I figure this redirection was left in from some debugging session, let's
fix it, and make the setup_basic_environment invocation like in all
other test scripts.

test-functions: don't nest KVM (#8883)
Nested KVM is very flaky as we learnt from our CI. Hence, let's avoid
KVM whenever we detect we are already running inside of KVM.

Maybe one day nested KVM is fixed, at which point we can turn this on
again, but for now let's simply avoid nested KVM, since reliable CI is
more important than quick CI, I guess.

And yes, avoiding KVM for our qemu runs does make things substantially
slower, but I think it's not a complete loss.

Inspired by @evverx' findings in:

80359410c4 sysusers: make sure to reset the returned value when EOF is reached in fget*ent_sane() wrappers (#8737)
To indicate that the there're no more entries, these wrappers return false but
did leave the passed pointed unmodified.

However EOF is not an error and is a very common case so initialize the output
argument to NULL even in this case so callers don't need to do that.

7e4a49b42b test-execute: make find invocation a bit more efficent, increase timeout
We go through the whole file system, so this test can take arbitrary time.  But
this test is still quite useful, so let's at least try to make it more efficent
by not descending at all into the directories we would filter out later on
anyway.

Also increase the timeout, in case the previous step doesn't help enough.

5008da1ec1 systemd: do not require absolute paths in ExecStart
Absolute paths make everything simple and quick, but sometimes this requirement
can be annoying. A good example is calling 'test', which will be located in
/usr/bin/ or /bin depending on the distro. The need the provide the full path
makes it harder a portable unit file in such cases.

This patch uses a fixed search path (DEFAULT_PATH which was already used as the
default value of $PATH), and if a non-absolute file name is found, it is
immediately resolved to a full path using this search path when the unit is
loaded. After that, everything behaves as if an absolute path was specified. In
particular, the executable must exist when the unit is loaded.

11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.
