cryptenroll: do not implicitly verify with default tpm policy signature
If it was not requested to use a tpm2 signature file when enrolling, do
not fallback to the default /run/systemd/tpm2-pcr-signature.json as it
likely will be unrelated if it exists.

ci: remove `if: github.event.issue.pull_request` from `labeler.yml`
`github.event.issue.pull_request` is an object, not a boolean.
This is the root cause of why the step that is supposed to remove labels
is always skipped. Having this condition in place is not necessary since
the workflow is run on the `pull_request_target` event.
logs-show: rename "ts" paramater/variable to "display_ts"
When displaying log data we deal with two kind of timestamps: the one we
use for display (typically the source timestamp if available), and the
one we use internally (typically the reception timestamp of journald).
The user-facing output modes generally use the display timestamp, the
ones intended for further processing (i.e. json + export outputs) do
not, and directly query the timestamps of the entry, ignoring the
source. This gets a bit confusing, since it's not always clear why we
use which timestamp where. Let's address that by renaming the generic
"ts" parameter/variable to "display_ts" to emphasize that the stored
timestamp are "corrected" timestamps for display only.
resolve: adjust message for NXDOMAIN lookup result
Previously, we reported:
nx.example.org: resolve call failed: 'nx.example.org' not found
But the call did succeed, and in fact all communication with the upstream
servers was successful, and we got an authoritative negative answer.
So instead of saying that the call fail, just say that the host doesn't exist:
nx.example.org: Name 'nx.example.org' not found
I wanted to keep the prefix of "<name>: ", to keep the output uniform. But
it'd look a bit strange to say "<name>: <name> not found", so I added "Name "
to make the output more readable. (Another option would be to not display
the error string received from resolved, but that seems risky: even if right
now resolved uses just one message format, it could start doing something else
in the future, so it's better to display the error as received.)
resolve: define normal macros for BUS_ERROR_DNS error codes
This result is identical after cpp is done, so we don't save anything
by not having the usual macros. And with the usual macros it's easier to
grep and code-crossreferencing works better.
The change was dropped due to the process name was not correctly logged,
but the issue was fixed by dd15e4cb57129b915e01495e113696bfe0b70214.
Let's set the child process name again.

argv-util: also update program_invocation_short_name
Our logging uses program_invocation_short_name. Without this patch,
logs from forked client may become broken; spuriously truncated or
the short invocation name is not completely shown in the log.
This will warn if fake flexible arrays are re-introduced. I'm not using
-Werror=… because we may still get warnings when compiling against old kernel
headers. We can crank this up to error later.
meson: enable -Warray-bounds and -fstrict-flex-arrays
-fstrict-flex-arrays means that the compiler doesn't have to assume that any
trailing array is a flex array. I.e. unless the array is declared without a
specified size, only indices in the declared range are valid.
-Warray-bounds turns on the warnings about out-of-bounds array accesses.
-Warray-bounds=2 does some more warnings, with higher false positive rate. But
it doesn't seem to yield any false positives in our codebase, so enable it.
clang supports -Warray-bounds, but not -Warray-bounds=2.
gcc supports both.
gcc-13 supports -fstrict-flex-arrays.
See https://people.kernel.org/kees/bounded-flexible-arrays-in-c for a long
discussion of use in the kernel.
I tried to use DECLARE_FLEX_ARRAY like the kernel does, but it does not work
for anonymous structs (they cannot be declared inline), so an open-coded
version is used.

This is with gcc-13.0.1-0.2.fc38.x86_64, -O2. I'm pretty sure the code

for gcc to understand.
test: drop whitespace after shell redirection operators
(The one case that is left unchanged is '< <(subcommand)'.)
This way, the style with no gap was already dominant. This way, the reader
immediately knows that ' < ' is a comparison operator and ' << ' is a shift.
In a few cases, replace custom EOF replacement by just EOF. There is no point
in using someting like "_EOL" unless "EOF" appears in the text.

ci: Fix Development Freeze Automation
Due to the limitation of `GITHUB_TOKEN` when running workflows from forks,
it's required to split the `development_freeze` workflow in two.
* First workflow will run on the `pull_request` trigger and save the PR
number in the artifact. This workflow is running with read-only permissions
on `GITHUB_TOKEN`.
* Second workflow will get triggered on `workflow_run`. It will be run
directly in the `systemd/systemd` context and can get permission to be
able to create comments on PR.
If the input timestamp is too old (say, 1min since 1970-01-01), then
parse_timestamp() may fail on a timezone with positive shift e.g.
JST (UTC+9). Moreover, even if parse_timestamp() succeeds, its result
'y' and 'usec_sub_unsigned(x, 2 * USEC_PER_DAY)' are both zero, and
the assertion will be triggered.
docs: tweak rsync flags for moving existing home dir to systemd-homed
The documentation on moving an existing homedir into a systemd-homed managed
one suggests using rsync(1) with a bunch of flags to preserve as much metadata
as possible: permissions, xattrs, timestamps, etc. The previously suggested
flags were:
rsync -aHAXv --remove-source-files …
… which does include mtimes, but not ctimes and atimes, because -a does not
include those:
--archive, -a archive mode is -rlptgoD (no -A,-X,-U,-N,-H)
This change adds the -N and -U flags to preserve even more file timestamps,
turning the command into:
rsync -aHANUXv --remove-source-files …
The new flags are:
--crtimes, -N preserve create times (newness)
--atimes, -U preserve access (use) times

core: split system/user job timeouts and make them configurable
Config options are -Ddefault-timeout-sec= and -Ddefault-user-timeout-sec=.
Existing -Dupdate-helper-user-timeout= is renamed to -Dupdate-helper-user-timeout-sec=
for consistency. All three options take an integer value in seconds. The
renaming and type-change of the option is a small compat break, but it's just
at compile time and result in a clear error message. I also doubt that anyone was
actually using the option.
This commit separates the user manager timeouts, but keeps them unchanged at 90 s.
The timeout for the user manager is set to 4/3*user-timeout, which means that it
is still 120 s.
Fedora wants to experiment with lower timeouts, but doing this via a patch would
be annoying and more work than necessary. Let's make this easy to configure.
