nss-resolve: expose various source-disablement settings as variables
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2006761:
> systemd-resolved always (reverse)-resolves the host's IP addresses and FQDN.
> This can be harmful when an application (for instance, a DNS zone manager) is
> installed on the same server instance. That application would expect
> NXDOMAIN to be returned if the current server's IP does not belong in an

This allows clients of nss-resolve to use the same config options that are
available through the dbus api and as command-line options to resolvectl.
The comment https://github.com/systemd/systemd/pull/21814#discussion_r771842132

Let's not add such, but simply replace the goto with a flag.

core: Add trigger limit for path units
When conditions fail on a service unit, a path unit can cause
PID 1 to busy loop as it keeps trying to activate the service unit.
To avoid this from happening, add a trigger limit to the path unit,
identical to the trigger limit we have for socket units.
Initially, let's start with a high limit and not make it configurable.
If needed, we can add properties to configure the rate limit similar
to the ones we have for socket units.

Now that kernel-install creates the machine-id directory, we don't need to do
this is 'bootctl install', and in fact it's better not to do this since it
might never be necessary. So let's change the default behaviour to 'no'.
I kept support for 'auto' to maintain backwards compatibility, even though the
default was changed. Previous behaviour can be requested by specifying
--make-machine-id-directory=auto.
bootctl: write KERNEL_INSTALL_LAYOUT=bls and KERNEL_INSTALL_MACHINE_ID=…
This is a natural extension of d6bce6e224: if we are installing sd-boot, we
want to use the sd-boot layout, so let's write the appropriate
KERNEL_INSTALL_LAYOUT setting. Effectively, if we do 'booctl install',
kernel-install will not autodetect the layout anymore.
And 357376d0bb added support for KERNEL_INSTALL_MACHINE_ID. We need to support
it here too. We both read it, so that we create the right directories, and also
write it if it wasn't written yet and we created some directories using it, so
that kernel-install that is executed later knows the machine-id that matches
the directories we crated.
The code is changed in some places to fail if we can't figure out the current
status. When installing the boot loader it's probably better not to guess.

test: adjust MemoryHigh= on oomd extended test units
On some runs `sleep infinity` run by the user manager uses over 3M of
memory, which is higher than the MemoryHigh= set on testbloat and
testmunch. If no pgscan is generated, then systemd-oomd sorts by memory
usage which leads to a situation where testchill (using 3M) could be
targeted over testbloat (1M-2M).
Fix this by setting reasonable MemoryHigh= values for all of these test
units. Even if somehow testchill throttles a bit at 3M, testbloat and
testmunch should still be trying to use over 100M at memory and will
throttle down to 5M and 6M with the new values. This should reflect
the desired state in pgscan and memory usage during the test run.

kernel-install: replace 00-entry-directory with K_I_LAYOUT in k-i
341890de866f2ee34919a47ce3fc6c8cd3c1924c made "bootctl install" create
ESP\MID, in preparation of cf73f650890b56a59bfb713c4c82b4e29daa7316 that
followed it and created 00-entry-directory.install to make ESP\MID\KVER
if ESP\MID existed ‒ this meant that "bootctl install" followed by
"kernel-install $(uname -r) /boot/vml*$(uname -r) /boot/ini*$(uname -r)"
actually installed the kernel correctly.
Later, 31e57550b552e113bd3d44355b237c41e42beb58 reverted the first
commit, meaning, that now running those two commands first installs
sd-boot, but then does nothing. Everything appears to work right,
nothing errors out, but no changes are actually done. To the untrained
eye (all of them), even running with -v appears to work:
all the hooks are run, as is depmod, but, again, nothing happens.
This is horrible. Nothing in either manpage suggests what to do
(nor should it, really), but the user is left with a bootloader that
appears fully funxional, since nothing suggests a failure in the output,
but with an unbootable machine, /no way to boot it/, even if they drop
to an EFI shell, since the boot bundle isn't present on the ESP,
and no real recourse even if they boot into a recovery system,
apart from installing like GRUB or whatever.
00- is purely instrumentation for 90-,
and separating one from the other has led to downstream dissatisfaxion
(indeed, the last mentioned commit cited cited exactly that as the
reversion reason), while creating $ENTRY_DIR_ABS is only required
for bootloaders using the BLS, and shouldn't itself toggle anything.
To that end, introduce an /{e,l}/k/install.conf file that allows
overriding the detected layout, and detect it as "bls" if
$BOOT_ROOT/$MACHINE_ID ($ENTRY_DIR_ABS/..) exists, otherwise "other" ‒
if a user wishes to select a different bootloader,
like GRUB, they (or, indeed, the postinst script) can specify
layout=grub. This disables 90- and $ENTRY_DIR_ABS manipulation.
The code was correct, but looked suspicious: we were comparing
strlen(x) with sizeof(y), with looks like an off-by-one. But we actually
want x to be one longer than y, so that's fine. Let's use STRLEN() to
make this more obvious.

meson: drop three more single-use convenience libraries
The way that the cryptsetup plugins were built was unnecessarilly complicated.
We would build three static libraries that would then be linked into dynamic
libraries. No need to do this.
While at it, let's use a convenience library to avoid compiling the shared code
more than once.
We want the output .so files to be located in the main build directory,
like with all consumable build artifacts, so we need to maintain the split
between src/cryptsetup/cryptsetup-token/meson.build and the main meson.build
file.
AFAICT, the build artifacts are the same: exported and undefined symbols are
identical. There is a tiny difference in size, but I think it might be caused
by a different build directory name.
meson: drop convenience library that was only used in one place
It doesn't make much sense to do this, the result is very similar to including
to objects directly in the output binary without going through an intermediate
target.
The linkage of test-libudev was rather strange too: udev_link_with is used to
allow udev to be linked to a static version of libshared, so that udev is not
linked to libshared.so. But here we were using both, defeating the purpose of
udev_link_with. I don't think it matters what the test is linked to, so let's
use the non-static linkage to save space.
meson: stop building out convenience libraries by default
The meson default for static_library() are:
build_by_default=true, install=false. We never interact with the
static libraries, and we only care about them as a stepping-stone towards
the installable executables or libraries. Thus let's only build them if
they are a dependency of something else we are building.
While at it, let's drop install:false, since this appears to be the default.
This change would have fixed the issue with lib_import_common failing
to build too: we wouldn't attempt to build it.
In practice this changes very little, because we generally only declare static
libraries where there's something in the default target that will make use of
them. But it seems to be a better pattern to set build_by_default to false.
Use a 'convenience library' to do the compilation once and then link the
objects into all the files that need it. Those files are small, so this probably
doesn't matter too much for speed, but has the advantage that we don't get the
same error four times if something goes wrong.
The library is conditionalized in the same way importd itself, because we
cannot build it without the deps.
man: split out a paragraph and shorten the text about sd-network-generator
The ordering of the service wrt. to udevd is enforced by unit configuration,

It is used by udevd and networkd. Since udevd is enabled statically, let's also
change the preset to "on". networkd is opt-in, so let's pull in the generator
when enabling networkd too.
