test-execute: drop capabilities when testing with user manager
Before this, tests are split into two categories, system and user, but
both are running in fully privileged environment. Hence, unprivileged
user scope was mostly not covered by the test.
Let's run all tests in both system and user scopes, and drop capabilities
when Manager is running in user scope.
This also makes the host environment protected more from the test run.
dissect-image: unknown/unsupported diskseq is indicated by 0, not by UINT64_MAX
At almost all places if diskseq is not supported we encode this as
diskseq zero. But in two places we got the check for that wrong,
assuming it was UINT64_MAX.

mkosi: Update to latest
Let's make sure we're testing unprivileged builds properly. Usage
of SourceFileTransfer= and SourceFileTransferFinal= are removed as
they were dropped by mkosi. SourceFileTransfer=mount is now the
default in mkosi so behavior for the build script is unchanged. We
stop copying sources in the final image until mkosi adds support
for virtiofs.

boot: Fix undefined reference to raise() on arm
This is just a workaround. Once we drop gnu-efi, the arm build system
for EFI binaries should be changed to use the arm-none-eabi toolchain,
which should not exhibit this behavior.
Follow-up for 4453ebe4db0511d25bed1040930ea6430c1bed91.
With the feature list all dandified, the most important part of the
output, i.e. the project name and version, are less visible.
journald: fix ignored filtering patterns for delegated cgroups
If a service defines Delegate=yes, its subcgroup won't inherit the
LogFilterPatterns= option, because the option is stored on the unit's
cgroup attributes, not on the subcgroup.
Fixed by using the unit's cgroup attributes instead.
From a given cgroup path, cg_path_get_unit() allows to retrieve the
unit's name. Although, this removes the path to the unit's cgroup,
preventing the result to be used to fetch xattrs.
Introduce cg_path_get_unit_path() which provides the path to the unit's
cgroup. This function behave similarly to cg_path_get_unit() (checking
the validity and escaping the unit's name).
manager: improve message about Reload/Reexec requests
If we fail to get the necessary information, let's just not print that
part of the message. 'n/a' looks pretty ugly.
I used a bunch of ternary operators instead of seperate log lines because
with two components that might or might not be there, we need four different
combinations.
Also, the unit name doesn't need to be quoted, it's always printable.
manager: "downgrade" message about command vanishing from the unit file
We would print "Current command vanished from the unit file, execution of
the command list won't be resumed." as a warning, but most of the time there
is nothing to resume, because a unit has just one command. So let's detect
the case where the command that was active is the last command in the sequence
and skip the warning.
I was considering how to store the information that the command is last. An
important consideration is not to use a format that would confuse older versions
of systemd. (It wouldn't be a big problem if older systemd just refused the
new serialization, since we require systemd to be newer, but we should avoid
the case where the deserialization is "successful", but actually incorrect.)
Similarly, the deserialization from the old systemd must not confuse new systemd.
For this command, we have a list of arguments at the end, so just adding a
new field either in the middle or at the end is problematic because it's hard
to ensure that we don't mix up the positional and variable arguments.
We actually need to store just one bit of information, so '+' is prefixed on
the index of the last command and used by new systemd to skip the warning.
When deserializing from older systemd, '+' is not present, so we detect all
commands as "not last", and still emit the warning, so we err on the side of
caution. If the user were to deserialize from newer to older systemd, nothing
untoward would happen, because the '+' is ignored. (Users shouldn't do this,
but we know that this occasionally happens with initrds or exitrds and package
downgrades.)

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.

(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.
