Merge pull request #18580 from keszybz/signal-list
Add systemctl --signal=list

97ab9dfc0d systemctl,loginctl,machinectl: add --signal=list
This lists numerical signal values:
$ systemctl --signal list
SIGNAL NAME
1      SIGHUP
2      SIGINT
3      SIGQUIT
...
62     SIGRTMIN+28
63     SIGRTMIN+29
64     SIGRTMIN+30

This is useful when trying to kill e.g. systemd with a specific signal number
using kill. kill doesn't accept our fancy signal names like RTMIN+4, so one
would have to calculate that value somehow. Doing
  systemctl --signal list | grep -F RTMIN+4
is a nice way of doing that.

86beb21302 systemctl,loginctl,machinectl: use a shared helper for arg_signal
I seems frivolous to yet another two -util.[ch] files, but the helper
should be in shared/ and it doesn't seem to fit anywhere else.

f963f8953d networkd: add UseFQDN option for DHCPv6
Similar to DHCPv4's UseHostname option, add a UseFQDN config option in
[DHCPv6] to set the system's transient hostname if the FQDN option is
set in the DHCPv6 response from the server.

e26fe5f911 portable: add 'reattach' verb and DBUS interface
Add 'reattach' verb to portablectl, and corresponding DBUS interface
to systemd-portabled.
Takes the same parameters as 'attach', but it will do a 'detach' (and
it will refuse to proceed if it cannot be done) first, matching on
the unversioned prefix of the new image. Eg:

portablectl reattach /tmp/foo_2.raw

will cause foo_1.raw to be detached, and foo_2.raw to be attached.

The key difference with a manual 'detach old' plus 'attach new' is that
the running units are not disturbed until after the attach completed,
and if --now is passed they are then restarted.
A 'detach' is not allowed normally if the units are running.

By using a restart-after-deploy method, 'reattach' allows for minimal
interruption of service and also for features that only work on restart
(eg: file descriptor store) to work as intended.

The DBUS interface returns two lists: first the removals from the detach
that were not immediately re-added in the attach, so that the caller
can stop the relevant units, and then the list of additions that are
either new or updates, so that the caller can restart/enable the
relevant units. portablectl already implements this with the existing
--now/--enable switches.

1f8dc96c06 udev: rename TxQueueLength= -> TransmitQueueLength=
As we usually (unfortunately not always though) do not use abbreviations.

Tx may be standard abbreviation, but we already have e.g.
TransmitChecksumOffload=. So, let's use Transmit instead of Tx.

7e215af765 man: move content from the wiki to systemd.preset(5)
The wiki was slightly stale, and almost all the information there
was already present in the man page. I moved the remaing part (discussion)
into the man page and adjusted all links to point to the man page instead.

daemon(7) has a some examples of packaging scriptlets… I don't think it fits
there very well. Most likely they should be moved to systemd.preset(5) or maybe
even removed, but I'm leaving that for later.

GetMulticastHosts() returns an array of hostnames/addresses discovered via
LLMNR or Multicast DNS. It does not trigger any discovery on its own.
Instead, it simply returns whatever is already in resolved's cache.

9c587d6618 man: make it clear how systemd calculate the DefaultTasksMax.
Actually, systemd takes the minimum of 
* a) the maximum tasks value the kernel allows on this architecture
* b) the cgroups pids_max attribute for the system
* c) the kernel's configured maximum PID value
to calculate the DefaultTasksMax. Here, kernel.thread-max should also be methioned.

ddc155b2fd New directives NoExecPaths= ExecPaths=
Implement directives `NoExecPaths=` and `ExecPaths=` to control `MS_NOEXEC`
mount flag for the file system tree. This can be used to implement file system
W^X policies, and for example with allow-listing mode (NoExecPaths=/) a
compromised service would not be able to execute a shell, if that was not
explicitly allowed.

Example:
[Service]
NoExecPaths=/
ExecPaths=/usr/bin/daemon /usr/lib64 /usr/lib

Closes: #17942.

4c890ad3cc meson: rename target to update-dbus-docs
Very old versions of meson did not include the subdirectory name in the
target name, so we started adding various "top-level" custom targets in
subdirectories. This was nice because the main meson.build file wasn't
as cluttered. But then meson started including the subdir name in the
target name. So let's move the definition to the root so we can have all
targets named uniformly.

eb83eb63b8 sd-bus: Add sd_bus_reply()
While sd-bus already provides sd_bus_call() for calling a method
from a complete bus message object, We don't have an equivalent
function for replying from a method with a complete bus message
object.

Currently, we use sd_bus_send(call->bus, m, NULL) instead. Let's
add a shorthand for this pattern and name it sd_bus_reply().

44bc7f4fcf meson: Fix update-man-rules when the build dir is not a subdir of the project dir
Until now, update-man-rules assumed that the build directory was
a subdirectory of the project directory. When using mkosi, this is
not the case. We use find instead of git ls-files because git ls-files
does not seem to support outputting absolute paths.

Also, this makes update-man-rules a bit more user-friendly as new manpages
don't have to be added to the git staging area before they are processed by
update-man-rules.py.

17547fb5cb dissect: almost port systemd-dissect to table_print_with_pager()
This doesn't actually port systemd-dissect to table_print_with_pager()
but at least rearranges things so that similar behaviour is exposed. The
reason it's not ported over 1:1 is that systemd-dissect actually adjusts
the JSON output of the table with additional info, and doesn't print the
table 1:1 as JSON.
