The mkosi Arch CI doesn't work as the keyring package is out
of date and cannot be built due to various build toolchain
issues. Disable the job as it always fails and confuses
submitters.
This commit doesn't look right to me. We have to unmount everything
recursively *before* we MS_MOVE because the MS_MOVE will not get rid of
it for us, and we simply cannot access these mounts after the MS_MOVE is
complete anymore.
This is a fundamental difference between MS_MOVE and pivot_root(). The
latter repivots the entire mount table getting rid of anything outside
of the new root. MS_MOVE otoh just mounts a bunch of mount points to the
top, leaving in place whatever might be underneath it.
Thus, if we go through the MS_MOVE codepath we must unmount everything
explicitly before doing so because otherwise the mounts will be pinned
forever, but be entirely invisble to userspace.
switch-root: when pivot_root() fails, but old root shall be mounted, do so
If pivot_root() fails, we'll fall back to switching root via MS_MOVE.
Unlike pivot_root() that won't place the old root fs anyway, but just
hide it. That's problematic during shutdown for example, since after all
we might still want to access it from the exitrd, to disassemble it
properly.
Hence let's make things somewhat systematic: regardless if pivot_root()
or MS_MOVE is used, always make the old root fs show up in the selected
new dir.
switch-root: rework SWITCH_ROOT_SKIP_RECURSIVE_RUN flag
Negative flags always raise eyebrows. Let's normalize
SWITCH_ROOT_SKIP_RECURSIVE_RUN to become SWITCH_ROOT_RECURSIVE_RUN, i.e.
make recursive behaviour opt-in, rather than opt-out. We only want it
for the initrd→host transition, and in all other cases we'd prefer to
avoid it.
This allows us to simplify some code. Also, normalize the mount point
table in switch_root() a bit, to be static const, and then just select
between two mount flag sets via SWITCH_ROOT_RECURSIVE_RUN, where the
mount flag without MS_BIND (i.e. zero) just means "skip this entry".
This does not actually change anything in behaviour, it's just
refactoring.
I'm keeping this as a separate commit. It is the first time version
information is manually added after 6a73a4f7c466887a03c9939300ba6864203b1b3f
and we might want to revert this later.
This is not good, because it breaks our promise that the base (usually either
machine-id or boot-id) cannot be derived from the result. Some application
using the library could use a null app id, inadvertently exposing the machine
or boot id. (This could happen because of forgotten initialization, or maybe
because the app id is configurable, and the user configures it wrongly.)
No functional change. In config_parse_address_generation_type() we would set
the output parameter and then say it's ignored, so it _looked_ like an error in
the code, but the variable was always initialized to SD_ID128_NULL anyway, so
the code was actually fine.
From RFC 4861 section 4.2.

Hence, based on the lifetime field of the message header, we should not
drop any other information.
Note that, in ndisc_router_process_default(), we have already dropp the
default gateway when the lifetime is zero. Hence, we can safely drop the
change.
oomd: avoid unnecessary wake-ups for ManagedOOMSwap
If there are no "ManagedOOMSwap" entries to monitor, then the event source
can be completely disabled. This scenario appears to be common and avoiding
the wake-ups can save idle energy consumption.
This was discovered while using Sysprof for various GNOME 45 performance
tuning. systemd-oomd goes from waking up a few times a second to no
wake-ups helping keep a laptop in deep(er) sleep.

sd-login: Fix sd_pidfd_* function signature parameter types

glyph-util: bring glyphs into same order everywhere
The enum definition, the two string tables and the test all were using

table the canonical one, adjusting the other lists to match it. And adds
the missing entries to the tets.

journal: Relax boot ID and monotonic clock consistency checks
The monotonic clock value consistency should only be checked if the boot
ID is the same as the last journal entry, and requiring that the current
boot ID be the same as the boot ID of the last entry is not necessary
for ensuring deterministic bisection as we already enforce strict
ordering of the real time clock value in a single journal file.
This fixes an issue where a new journal file is unnecessarily created
every boot, potentially wasting storage space.

journal: Don't write to journal files without the new boot ID update behavior guarantee
With the old boot ID update behavior there's no way to compare the boot
ID of a new entry to be written with the boot ID of the last entry in
the journal in a performant manner, and therefore no way to determine if
monotonic clock value consistency checking is needed. Refuse to open
journal files without the new boot ID update behavior guarantee to
simplify consistency checking.
tpm2: whenever we measure, also write a tpm log record
Previously we only logged our measurements to the journal. This is not a
great solution though, since regular logs are subject to rotation, which
is something we really cannot have for measurements (as it means we can
never reproduce the PCR values from the data). Hence, let's maintain an
explicit log.
Ideally, we'd just use the TCG Canonical Event Log format 1:1
(https://trustedcomputinggroup.org/resource/canonical-event-log-format/).
However it's not a perfect fit fo us, for various reasons. But let's
follow it (in its JSON incantation) as closely at it makes sense, so
that it can easily be converted to the full format by programs consuming
it.
Code comments explain where we deviate from the TCG CEL-JSON, and what
to do about it when reading the data.

sd-dhcp-client: ensure IAID and DUID being set on start

We exported sd_id128_get_machine_app_specific() and
sd_id128_get_boot_app_specific(). But those operate on the current machine,
and sometimes the user might want to do the same calculation for a different

We can use version_h directly, since we already have it.

There's really no point in first extracting a command line from an UKI

Let's drop this, so that unless the user actually edits the cmdline we
pass nothing to the invoked kernel.
Note that this low-key is a compat break, since the passed cmdline gets
measured. However, in the interest of minimized the difference between
systems with and without sd-boot to behave the same i think we should
suppress the command line anyway.
