Ambient capabilities should not be passed implicitly to user

which are important for the manager itself to operate.

Inspired by https://github.com/systemd/systemd/pull/24024 this is
another user mode helper, where this might be an issue. hence let's
rather be safe than sorry, and also connect stdin/stdout/stderr
explicitly with /dev/null.

When invoked as the coredump handler by the kernel, systemd-coredump's
stdout and stderr streams are closed. This is dangerous as this means
the fd's can get reallocated, leading to hard to debug errors such as
log messages ending up being appended to a compressed coredump file.
To avoid such issues in the future, let's bind stdout/stderr to
/dev/null so the file descriptors can't get used for anything else.

Let's not allow anyone to look into /root/ if we create it via the

for /root/, in case we create it if it happens to be missing.

This allows growfs to expand the filesystem even when the underlying
block device cannot be expanded. This has been useful for example on
LUKS devices that have already been expanded using systemd-repart.
This works around the following error:
```
root@mobian:/home/mobian# /usr/lib/systemd/systemd-growfs /
crypt_resize() of /dev/block/179:2 failed: Operation not permitted
```
(cherry picked from commit e9a28b8ccd)
(cherry picked from commit 378e187ed4)
This causes systemd-growfs to exit before resizing the partition when
`--dry-run` is passed. Resizing during a dry run of a change breaks the
users expectations.

In most cases, it is not necessary to call them without retrieving

Newer binutils versions currently trigger the following warnings due to
a bug in gnu-efi
on arm64:
/usr/bin/ld.bfd: warning: src/boot/efi/systemd-bootaa64.elf has a LOAD segment with RWX permissions
on amd64:
/usr/bin/ld.bfd: warning: /usr/lib/crt0-efi-x86_64.o: missing .note.GNU-stack section implies executable stack
This results in a build failure due to --fatal-warnings.
Work around this issue by suppressing those warnings until gnu-efi has
been fixed.

dm-crypt device units generated by systemd-cryptsetup-generator
habe BindsTo= dependencies on their backend devices. The dm-crypt
devices have the db_persist flag set, and thus survive the udev db
cleanup while switching root. But backend devices usually don't survive.
These devices are neither mounted nor used for swap, thus they will
seen as DEVICE_NOT_FOUND after switching root.
The BindsTo dependency will cause systemd to schedule a stop
job for the dm-crypt device, breaking boot:
[ 68.929457] krypton systemd[1]: systemd-cryptsetup@cr_root.service: Unit is stopped because bound to inactive unit dev-disk-by\x2duuid-3bf91f73\x2d1ee8\x2d4cfc\x2d9048\x2d93ba349b786d.device.

[ 69.473459] krypton systemd[1]: systemd-cryptsetup@cr_root.service: Installed new job systemd-cryptsetup@cr_root.service/stop as 343
Avoid this by not setting the state of the backend devices to
DEVICE_DEAD.

Commit 70e74a5997 ("pstore: Run after modules are loaded") added After=
and Wants= entries for all known kernel modules providing a pstore.
While adding these dependencies on systems where one of the modules is
not present, or not configured, should not have a real affect on the
system, it can produce annoying error messages in the kernel log. E.g.
"mtd device must be supplied (device name is empty)" when the mtdpstore
module is not configured correctly.
Since dependencies cannot be removed with drop-ins, if a distro wants to
remove some of these modules from systemd-pstore.service, they need to
patch units/systemd-pstore.service.in. On the other hand, if they want
to append to the dependencies this can be done by shipping a drop-in.
Since the original intent of the previous commit was to fix [1], which
only requires the efi_pstore module, remove all other kernel module
dependencies from systemd-pstore.service, and let distros ship drop-ins
to add dependencies if needed.

(cherry picked from commit 8b8bd621e1)
The systemd-pstore service takes pstore files on boot and transfers them
to disk. It only does it once on boot and only if it finds any. The typical
location of the pstore on modern systems is the UEFI variable store.
Most distributions ship with CONFIG_EFI_VARS_PSTORE=m. That means, the
UEFI variable store is only available on boot after the respective module
is loaded.
In most situations, the pstore service gets loaded before the UEFI pstore,
so we don't get to transfer logs. Instead, they accumulate, filling up the
pstore over time, potentially breaking the UEFI variable store.
Let's add a service dependency on any kernel module that can provide a
pstore to ensure we only scan for pstate after we can actually see pstate.
I have seen live occurences of systems breaking because we did not erase
the pstates and ran out of UEFI nvram space.

On switching root, a device may have a persistent databse. In that case,
Device.enumerated_found may have DEVICE_FOUND_UDEV flag, and it is not
necessary to downgrade the Device.deserialized_found and
Device.deserialized_state. Otherwise, the state of the device unit may
be changed plugged -> dead -> plugged, if the device has not been mounted.
Fixes#23429.
[mwilck: cherry-picked from #23437]
(cherry picked from commit 4fc69e8a09)
(cherry picked from commit 131206de78)
The issue #12953 is caused by the following:
On switching root,
- deserialized_found == DEVICE_FOUND_UDEV | DEVICE_FOUND_MOUNT,
- deserialized_state == DEVICE_PLUGGED,
- enumerated_found == DEVICE_FOUND_MOUNT,
On switching root, most devices are not found by the enumeration process.
Hence, the device state is set to plugged by device_coldplug(), and then
changed to the dead state in device_catchup(). So the corresponding
mount point is unmounted. Later when the device is processed by udevd, it
will be changed to plugged state again.
The issue #23208 is caused by the fact that generated udev database in
initramfs and the main system are often different.
So, the two issues have the same root; we should not honor
DEVICE_FOUND_UDEV bit in the deserialized_found on switching root.
This partially reverts c6e892bc0e.
Fixes#12953 and #23208.
Replaces #23215.

This fixes formatting of JSON real values, and uses C locale for them.
It's kinda interesting that this wasn't noticed before: the C locale
object we allocated was not used, hence doing the dance had zero effect.
This makes "test-varlink" pass again on systems with non-C locale.
(My guess: noone noticed this because "long double" was used before by
the JSON code and that had no locale supporting printer or so?)

They are various cases where the same module might be repeatedly
loaded in a short time frame, for example if a service depending on a
module keep restarting, or if many instances of such service get
started at the same time. If this happend the modprobe@.service
instance will be marked as failed because it hit the restart limit.
Overall it doesn't seems to make much sense to have a restart limit on
the modprobe service so just disable it.

Commit 0307afc681 ("networkctl: add support to display Transmit/Recieve queue
length (#12633)") added the display of the number of RX and TX Queues to the
output of `networkctl status $DEV`. However the row description says "Queue
Length".
This patch fixes the output by replacing "Queue Length" by "Number of Queues".
