F40 will be out soon, so we can update the man page already. The example should
already work.
The cloud link was dropped in fd571c9df0, so
drop the unused variable too.
- Install individual asan libraries instead of gcc
- Drop duplicate qrencode package from arch config
- Install dbus-user-session which provides default-dbus-session-bus
- Explicitly install dbus-broker on Arch Linux
Unfortunately, sd-bus-vtable.h, sd-journal.h, and sd-id128.h
have variadic macro and inline initialization of sub-object, these are
not supported in C90. So, we need to silence some errors.
Also install setools-console and policycoreutils instead of setools
which pulls in the kitchen sink. Also install selinux-policy-targeted
to make sure the right policy is installed.
At that point the options have been parsed, sent and received again so
`ndisc_parse_options` should never fail there (unless ndisc_send corrupts
them somehow).
It's a follow-up to https://github.com/systemd/systemd/pull/31807
To make it easy to have a workable ssh-generator on various distros,
let's optionally generate the ssh privsep dir via tmpfiles.d/ drop-in.
This enables the concept with a path of /run/sshd/ as default. This is
the path Debian/Ubuntu uses, and means that we just work on those
distros. Debian/Ubuntu is the only distro (apparently?) that puts the
privsep dir under /run/, hence always needs the dir to be created
manually. Other distros don't need it that much, because they place the
dir in /usr/ (fedora, best choice!) or /var/ (others, not ideal, because
still mutable).
Also adds a longer explanation about this in NEWS, in the hope that
distro maintaines read that and maybe start cleaning this up.

I think the example should reflect the full set of lifecycle messages,
including STOPPING=1, which tells the service manager that the service
is already terminating. This is useful for reporting this information
back to the user and to suppress repeated shutdown requests.
It's not as important as the READY=1 and RELOADING=1 messages, since we
actively wait for those from the service message if the right Type= is
set. But it's still very valuable information, easy to do, and completes
the state engine.
stale HibernateLocation EFI variable
Currently, if the HibernateLocation EFI variable exists,
but we failed to resume from it, the boot carries on
without clearing the stale variable. Therefore, the subsequent
boots would still be waiting for the device timeout,
unless the variable is purged manually.
There's no point to keep trying to resume after a successful
switch-root, because the hibernation image state
would have been invalidated by then. OTOH, we don't
want to clear the variable prematurely either,
i.e. in initrd, since if the resume device is the same
as root one, the boot won't succeed and the user might
be able to try resuming again. So, let's introduce a
unit that only runs after switch-root and clears the var.
Fixes#32021
Device mapper devices are set up in multiple steps. The first step, which
generates the initial "add" event, only creates an empty container, which is
useless for higher layers. SYSTEMD_READY should be set to 0 on this event to
avoid premature device activation.
The event that matters is the "activation" event: the first "change" event on
which DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 is not set. When this event arrives,
the device is ready for being scanned by blkid and similar tools, and for being
activated by systemd.
Intermittent events with DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 should be ignored
as far as systemd or higher-level block layers are concerned. Previous device
properties and symlinks should be preserved: the device shouldn't be scanned or
activated, but shouldn't be deactivated, either. In particular, SYSTEM_READY
shouldn't be set to 0 if it wasn't set before, because that might cause mounted
file systems to be unmounted. Such intermittent events may occur any time,
before or after the "activation" event.
DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 can have multiple reasons. One possible reason
is that the device is suspended. There are other reasons that depend on the
device-mapper subsystem (LVM, multipath, dm-crypt, etc.).
The current systemd rule set
1) sets SYSTEMD_READY=0 if DM_UDEV_DISABLE_OTHER_RULES_FLAG is set in "add"
events;
2) imports SYSTEMD_READY from the udev db if DM_SUSPENDED is set, and jumps to systemd_end;
3) sets SYSTEMD_READY=1, otherwise.
This logic has several flaws:
* 1) can cause file systems to be unmounted if an coldplug event arrives while
a file system is suspended. This rule shouldn't be applied for coldplug events
or in general, "synthetic" add events;
* 2) evaluates DM_SUSPENDED=1, which is a device-mapper internal property.
It's wrong to infer that a device is accessible if DM_SUSPENDED=0.
The jump to systemd_end may cause properties and/or symlinks to be lost;
* 3) is superfluous, because SYSTEMD_READY=1 is equivalent with SYSTEMD_READY
being unset, and can create the wrong impression that the device was explicitly
activated.
This patch fixes the logic as follows:
- apply 1) only if DM_NAME is empty, which is only the case for the first
"genuine add" event;
- change 2) to use DM_UDEV_DISABLE_OTHER_RULES_FLAG instead of DM_SUSPENDED,
and remove the GOTO directive;
- remove 3).
Fixes: b7cf1b6 ("udev: use SYSTEMD_READY to mask uninitialized DM devices")
Fixes: 35a6750 ("rules: set SYSTEMD_READY=0 on DM_UDEV_DISABLE_OTHER_RULES_FLAG=1 only with ADD event (#2747)")

gcrypt is used only for journal sealing operations in libsystemd, so it
can be made into a dlopen dependency that is used only on demand. This
allows to reduce the footprint of libsystemd in the most common cases.
Keep systemd-pull and systemd-resolved with normal linking, as they are
executables, and usually built with OpenSSL support anyway.
If SD_BUS_METHOD_WITH_ARGS() is set with SD_BUS_NO_ARGS and/or SD_BUS_NO_RESULT,
then it introduces
_SD_VARARGS_FOREACH_EVEN(_SD_ECHO, NULL)
-> _SD_VARARGS_FOREACH_SEQ(_01, …, _50, NULL)
Hence, the variadic argument `...` in _SD_VARARGS_FOREACH_SEQ() has no
argument, but it is not allowed if built without GNU extension, e.g. -std=c11.
Let's introduce one more unused dummy argument to support such situation.
Also, this drops Weblate (again) and dependabot from the contributers list.
Moreover, this makes the contributers sorted by git command, rather
than sort command. Then, the authors are sorted by their first name, e.g.

Prep work for running the integration tests with meson, which requires
tests to exit with 77 to indicate they are skipped.
Note this only deals with the easy cases where there's only tests. The
hard ones where there's subtests of which only some are skipped are left
for another PR.
These are only used in the importd binary, which is a leaf optional
binary that also depends on libcurl, so it's not worth the
additional complications
