Enable the exec_fd logic for Type=notify* services too, and change it
to send a timestamp instead of a '1' byte. Record the timestamp in a
new ExecMainHandoverTimestamp property so that users can track accurately
when control is handed over from systemd to the service payload, so
that latency and startup performance can be trivially and accurately
tracked and attributed.
Right now systemd-tpm2-setup-early and systemd-pcrphase-initrd.service
are not ordered against each other. However, they require the same slow
resource to operate: the TPM2. If we allow them to access the device
simultaneously, the kernel resource manager like has to save/restore TPM
state while they operate, slowing things down further.
hence, let's avoid all this mess, and just order them against each other
so that the shared resource is first used in full by one and then by the
other.
I opted to order systemd-pcrphase-initrd before
systemd-tpm2-setup-early, since there's value in having the former as
early as possible in userspace, to be a good marker for the transition
from kernel to first userspace. I can see no benefit in the opposite
order however.
Replaces #32062
As discussed in #32062, making 'help' the default verb
is not very appealing for two reasons:
1) If the verb is missing, showing a help which is pages long
isn't really helpful to locate the problem.
(https://github.com/systemd/systemd/pull/32062#issuecomment-2064997158)
2) We want to reserve the right to set default verbs to be
more useful ones, instead of help. E.g. 'busctl' lists all
bus peers by default.
So, when there are more than 2 verbs, let's instead add
the list of available verbs to the "Command verb required"
message, that serves as a hint. That way we try to be friendlier
to users, but still make the problem obvious.
We shouldn't try to use any ANSI escape sequences if TERM=dumb.
Also, the "\r\n" we output can get interpreted as a double newline
(for example by Github Actions), so let's output just "\n" when
TERM=dumb to clean up the CI logs.
We so far just print a short log message that is not very useful, let's
add some recognizable error codes, and output better log messages if we
can't get TPM stuff to work.
Fixes: #31925
When an IO event source owns relevant fd, replacing with a new fd leaks
the previously assigned fd.
===
sd_event_add_io(event, &s, fd, ...);
sd_event_source_set_io_fd_own(s, true);
sd_event_source_set_io_fd(s, new_fd); <-- The previous fd is not closed.
sd_event_source_unref(s); <-- new_fd is closed as expected.
===
Without the change, valgrind reports the leak:

I'm working on the transition to merged sbin in Fedora. While the transition is
happening (and probably for a while after), we need to compile systemd with
split-bin=true to support systems upgraded from previous versions. But when the
system has been upgraded and already has /usr/sbin that is a symlink, be nice
and give $PATH without sbin.
We check for both /usr/sbin and /usr/local/sbin. If either exists and is not a
symlink to ./bin, we retain previous behaviour. This means that if both are
converted, we get the same behaviour as split-bin=false, and otherwise we
get the same behaviour as before.
sd-path uses the same logic. This is not a hot path, so I got rid of the nulstr
macros that duplicated the logic.
If we're already running in a unit with delegation turned on, let's
skip allocation of a scope unit and cgroup subroot. This allows journald
to correctly attribute the logs of all subprocesses spawned by tests such
as test-execute to the test-execute service when the test is running in a service.
Specifically, this will make tests log to the journal if stderr is
connected to the journal. This means we get proper log priorities
and such compared to if we just logged to stderr.
These don't get pulled in automatically and there doesn't seem to
be a "system-users" package so install the ones we need for the
integration tests manually.
CentOS does not ship these sysusers dropins which set up basic system
users and groups. Until we can move to CentOS Stream 10, let's add the
dropins ourselves to make sure the base system users/groups are available
on CentOS.
The Arch Linux PKGBUILD does not (yet) have versioned dependencies
between the systemd packages, causing systemd-libs to not get updated
to 256-devel if systemd 256-devel is installed. Let's explicitly install
the newer version of systemd-libs as well for now until this problem is
fixed.
This introduces dependencies on various environment variables set
by rpmbuild which will not be set when rerunning meson inside the
VM/container so let's disable package notes to avoid these dependencies,
as the package notes aren't terribly useful in this scenario anyway.
