On i386 with musl and libucontext, many tests crash with SIGSEGV
when using fibers implemented on top of ucontext APIs.

Building systemd with -mstackrealign makes all observed failures
disappear, suggesting a stack alignment issue in the interaction
between compiler-generated code and the ucontext implementation.
This resembles historical stack alignment issues in glibc's i386
makecontext() implementation, which required fixes to preserve the
expected stack alignment.
As a workaround, add -mstackrealign when building on i386 with musl
and libucontext.

sysext: utimensat() failure was logged with stale r (which is 0 after
the preceding successful write_backing_file call). Pass errno instead
so the actual failure reason is recorded and returned.
sysusers: rename() failure in make_backup() returned the raw positive
errno value. All callers check 'if (r < 0)', so the error was silently
ignored, allowing execution to continue after a failed backup. Return
-errno instead.

The suse spec now uses:
%{_mandir}/man3/*.3%{?ext_man}
which defaults to .gz and fails, as we disable compression.
Redefine it to avoid a build failure:
Processing files: systemd-doc-260.2-00.noarch
error: File not found: /var/tmp/BUILD/systemd-260.2-build/BUILDROOT/usr/share/man/man3/*.3.gz
The condition on line 1206 checks other->load_state != UNIT_STUB to
decide whether to call the vtable done() callback, but the state was
already overwritten to UNIT_MERGED on line 1198, making the condition
always true.
Save the original load_state before overwriting it, so that units in
UNIT_STUB state (which never went through a load attempt) correctly
skip the done() call.

The only runtime trigger for registry cleanup is the BPF kprobe that fires
on user namespace destruction; when it is missed (ring buffer overflow,
kprobe missing, fdstore entry dropped), the dead namespace's registry entry
survives and keeps its UID/GID ranges blocked until the manager restarts and
its startup sweep runs. The allocation hot path checked whether a candidate
range was already taken but never whether the namespace holding it was still
alive, so a single dead namespace could permanently starve an allocation.
This is most visible when a parent delegates its entire container UID window
to a child that then dies: every subsequent allocation from the parent fails
with NoDynamicRange even though the ranges are reclaimable.
Add userns_registry_reap_if_dead(), which probes a registered namespace's
liveness via the kernel namespace identifier recorded at allocation time and,
if it is authoritatively dead, releases its registry entry — restoring any
ranges it received via delegation to their ancestors. Call it from the
allocation availability check for both transient registrations and delegated
ranges, walking a chain of dead ancestors in the delegation case. This
mirrors the existing inode-slot stale cleanup and makes allocation
self-healing without waiting for a restart.
The startup sweep grew the same load-probe-release logic, so route it through
the new helper too; its errno return distinguishes alive, no-recorded-id, and
unprobeable-environment cases so the sweep keeps its early-out when lookup by
id isn't possible at all.

We might want to add more state to the LUO session json payload,
so add a version (to allow clean compat breaks if needed) and nest
the current fdstore contents under a 'units' object, so that more
top-level data can be added in the future without breaking
backward compatibility.

fallback error string reflects the actual bus call failure, not the
accumulated result that was reset to 0 earlier.

But keep disabled by default, as they take a lot of resources,

When generator_write_initrd_root_device_deps() fails, the error was

663f0bf5cb stopped reusing the original block device fd whenever
partition scanning was requested (LO_FLAGS_PARTSCAN) but couldn't be
enabled on the device, so that nested partition tables on devices the
kernel won't scan (e.g. the pmOS/android case) get exposed via a real
loop device.
However that also forced a pointless loop device for any partition that
carries a file system directly, e.g. a btrfs subvolume mounted via
MountImages=. For multi-device btrfs this is fatal: the kernel rejects
seeing the same member via both the original partition and the loop
device, and the mount fails.
A loop device is only ever needed here to expose a nested partition
table. So only refuse the shortcut when the device actually carries one,
probed via gpt_probe(), instead of whenever partition scanning is
disabled. Devices carrying a file system directly (or nothing) take the
shortcut as before.
Add an integration test to cover the failure scenario of the original
issue.

We really want to use io.systemd.Report for the interface provided by
systemd-report itself, not by its backend. hence, rename the interface
that uploading plugins shall implement to io.systemd.Report.Uploader.
Note that we ideally should have a varlink interface definition for that
interface. if we had, we'd have noticed that earlier.
let's name the dir "/run/systemd/report.upload/" (rather than
"/run/systemd/metrics-upload/"). After all, these are reports that we
upload, not indiviudual metrics. And it would be particular confusing
since the dir to pick up metrics is called /run/systemd/report/, rather
than /run/systemd/metrics/. Hence the thing that deals with reports is
nmamed metrics, and the thing that deals in metrics is named reports...
