The kernel reports guest usage in guest/guest-nice and also includes it in
user/nice. By adding the guest and guest-nice values, we were counting
those ticks twice.

Rewrite procfs_cpu_get_usage() to use procfs_cpu_get_ticks() and fix the
accounting error.
`sd_dhcp_server_configure_pool()` calculated the maximum pool size
before checking whether `PoolOffset=` was inside the subnet.
Because the calculation used unsigned arithmetic, an offset beyond the
broadcast address could wrap around to a large value and pass validation.
For example, `PoolOffset=256` with a `/24` and `PoolSize=1` was accepted,
allowing the DHCP server to offer an address outside its configured subnet.
Reject offsets at or beyond the broadcast address before performing the
subtraction, and calculate the remaining pool size directly as
`broadcast_off - offset`.
BrowseServices(ifindex=0) may observe the same service on multiple
links. Treat the link index as part of the discovered service
identity so add and remove events remain link-scoped.
Use the per-service ifindex for RFC 6762 maintenance queries.
Share the service identity predicate between add and remove handling,
and propagate RR comparison errors instead of reporting removals.
Extend coverage for scoped-browser ifindex fallback, goodbye TTL
handling, and monotonic expiry updates.
The custom help() is replaced by a COMMAND() description, and
--introspect-cli is added. --help now goes through the pager, like other
commands with --no-pager.
The custom help() is replaced by a COMMAND() description, and

I tried a few different forms but couldn't find one that was clearly
better.
The custom help() is replaced by a COMMAND() description, and

and consistent between the prog and man page.

Synopses are adjusted. --user-unit/--unit without any unit names is
technically allowed, but not very meaningful, since it's the same as
the default mode. So [] is dropped. And the prog help string is then
adjusted to match the man page.
The custom help() is replaced by a COMMAND() description, and
--introspect-cli is added. "COMMAND…" is marked as optional, since
'cat' is the default verb.

After c9cd66ee3a and
c81b5d36b9, the comment about systemd-backlight
and systemd-veritysetup was outdated. We can test them as any other program.
Also, use an array to make list easier to extend in the future and
adjust $PATH so we don't need to care about the split between public
and non-public programs.
PID, UID, and GID are converted by sending struct ucred, however, TID
was not converted. Let's convert TID if corresponding pidfd exists, and
discards TID otherwise.
Fixes 4c7af7d9d1.
Since kernel v6.19, ioctl(PIDFD_GET_INFO) can return the set of
supported flags when PIDFD_INFO_SUPPORTED_MASK is specified.
This allows checking whether, e.g., PIDFD_INFO_COREDUMP_SIGNAL is
supported by the running kernel.

The connect callback is called after sd_varlink_server_add_connection()
succeeds. Do not call the disconnect callback for connections that have
not been established yet.
Previously, sd_varlink_server_add_connection_pair() did not decrement
the connection counters when json_stream_attach_fds() failed.
Set the ucred before calling json_stream_attach_fds() so that
sd_varlink_close() also decrements the counters when it fails.
This makes json_stream_attach_fds() and json_stream_connect_fd_pair()
leave the passed file descriptors with the caller on failure. Callers
should call TAKE_FD() only after a successful call.
Also make qmp_client_connect_fd() always take ownership of the passed
file descriptor, including on failure. Previously, ownership of the
passed file descriptor on failure was unclear and depended on where
the function failed.
The getty.auto credential is a textual configuration value, but credentials
are read as raw file contents. A value written by common text-file workflows
can therefore end in a newline, causing false\n to be rejected and ignored.
Reproducer:
printf 'false\n' > "$CREDENTIALS_DIRECTORY/getty.auto"
Before: getty units could still be generated because the credential was
ignored as invalid.
Expected: false\n is parsed the same as false and disables getty
generation.
Strip the value in getty-generator before parsing it. This keeps the
credential framework byte-preserving while applying text semantics where
getty.auto is consumed.

The securebits parsing code now recognizes 'no-cap-ambient-raise' (added
in Linux 4.3), 'exec-restrict-file', and 'exec-deny-interactive' (both
added in Linux 6.14). The '-locked' variants were added too.
The `exec-restrict-file` and `exec-deny-interactive` securebits are
particularly useful in combination with `RestrictFileSystemAccess=` to
allow developers to extend the "only execute immutable files" concept to
script interpreters. Those securebits are not documented in the
[`capabilities(7)`](https://man7.org/linux/man-pages/man7/capabilities.7.html)
manpage, only in the [Executability
check](https://docs.kernel.org/userspace-api/check_exec.html) kernel
docs.
Replace opaque built-in review behavior with explicit parallel review lenses for
correctness, concurrency, security, architecture, coding style, and regression
coverage, plus bounded domain-specific reviewers and independent validation.
Prefetch pull request discussion in the setup job while letting the read-only
review job fetch and inspect the full commit history without per-commit
worktrees.
Keep GitHub writes isolated to the setup and posting jobs, pin the Claude models
and CLI, and bound execution below the AWS credential lifetime. Materialize
review instructions from the trusted base revision and scope agent writes to the
structured result directory so untrusted pull request content cannot widen the
review authority.
Treat the posting job as the authoritative trust boundary: validate all
model-selected commits, paths, lines, and thread IDs, normalize degenerate line
ranges, bound sanitized output, and surface GitHub API failures in the tracking
comment before performing writes. Retain daandemeyer/systemd in the repository
allowlist so the workflow can be exercised end to end on the personal fork.
Manual runs against fork PR #15 covered OIDC authentication, sandboxing, result
artifact handoff, tracking-comment updates, and validation of posted output.
