These tests identify a couple of problems with OPT pseudo-RR parsing.
First, any TTL value with the high bit set is replaced with zero before
checking the record type. For most types this is correct, since TTLs
have the range of signed int32. But for OPT records where the TTL is
repurposed to hold the extended RCODE, EDNS version and flags, it means
that the high bit cannot be used in extended RCODEs. Any RCODE with the
high bit set will be read as zero.
Second, the DNS_PACKET_RCODE() function bit-shifts the extended RCODE by
24 places instead of 20, so that it ends up forming the lower 8 bits of
a 12-bit RCODE, instead of the upper 8 bits as intended.
We intend to fix these issues in other pull requests.

These are required by the bpf_tracing.h header in libbpf, see
https://github.com/libbpf/libbpf/blob/master/src/bpf_tracing.h.
bpf_tracing.h does have a few fallbacks in case __TARGET_ARCH_XXX
is not defined but recommends using the __TARGET_ARCH macros instead
so let's do that.
We calculate the amount of uncompressed data we can write by taking the limits
into account and halving it to ensure there's room for switching to compression
on the fly when storing cores on a tmpfs (eg: due read-only rootfs).
But the logic is flawed, as taking into account the size of the tmpfs storage
was applied after the halving, so in practice when an uncompressed core file
was larger than the tmpfs, we fill it and then fail.
Rearrange the logic so that the halving is done after taking into account
the tmpfs size.
Be explicit with the type, and more inline with our other code, that
likes to indicate the string char width in the name.
Also, switch to a fixed size type, since EFI variables should really be
binary exact the same on all archs.
These functions after all write EFI UTF-16 strings, i.e. are relatively
high-level, hence give them a specific name indicating the type, to
match our other helpers that have similar type suffixes.
Although being far from ideal and the first two test cases have to be run
before the setup phase otherwise they will fail, it still makes the test
suite look much better and easier to read
Let's make sure logind is accessible by the time user@.service runs, and
that logind stays around as long as it does so.
Addresses an issue reported here:
https://lists.freedesktop.org/archives/systemd-devel/2024-June/050468.html
This addresses an issued introduced by
278e815bfa, which dropped the a dependency
from user@.service systemd-user-sessions.service without replacement.
While dropping that dependency does make sense, it should have been
replaced with the weaker dependency on systemd-logind.service, hence fix
that now.
user@.service is after all a logind concept, hence logind really should
be around for its lifetime.
systemd-user-sessions.service is a later milestone that only really
should apply to regular users (not root), hence it's too strong a
requirement.
read_virtual_file() will only read up to page size bytes of data
from /sys/firmware/dmi/entries/.../raw so let's use read_full_file_full()
instead to make sure we read all data.
This should be safe since smbios11 data can be considered immutable
during the lifetime of the system.
