This fixes the logic of removing unnecessary routes configured by the
previously received RAs. Previously, we wrongly handled existing routes
could be updated, and unexpected routes would be kept.
- drop unnecessary call of ndisc_set_route_priority() at the beginning,
as it is called later in the loop below,
- use RET_GATHER() and remove all possible routes even if failed.
Some ambiguity (e.g., same-named man pages in multiple volumes)
makes it impossible to fully automate this, but the following
Python snippet (run inside the man/ directory of the systemd repo)
helped to generate the sed command lines (which were subsequently
manually reviewed, run and the false positives reverted):
from pathlib import Path
import lxml
from lxml import etree as ET
man2vol: dict[str, str] = {}
man2citerefs: dict[str, list] = {}
for file in Path(".").glob("*.xml"):
tree = ET.parse(file, lxml.etree.XMLParser(recover=True))
meta = tree.find("refmeta")
if meta is not None:
title = meta.findtext("refentrytitle")
if title is not None:
vol = meta.findtext("manvolnum")
if vol is not None:
man2vol[title] = vol
citerefs = list(tree.iter("citerefentry"))
if citerefs:
man2citerefs[title] = citerefs
for man, refs in man2citerefs.items():
for ref in refs:
title = ref.findtext("refentrytitle")
if title is not None:
has = ref.findtext("manvolnum")
try:
should_have = man2vol[title]
except KeyError: # Non-systemd man page reference? Ignore.
continue
if has != should_have:
print(
f"sed -i '\\|<citerefentry><refentrytitle>{title}"
f"</refentrytitle><manvolnum>{has}</manvolnum>"
f"</citerefentry>|s|<manvolnum>{has}</manvolnum>|"
f"<manvolnum>{should_have}</manvolnum>|' {man}.xml"

Let's gather generic key/certificate operations in a new tool
systemd-keyutil instead of spreading them across various special purpose
tools.
Fixes#35087
When an interface went down, IPv4 non-local routes are removed by the
kernel without any notifications. Let's forget the routes in that case.
Fixes#35047.
When a nexthop is removed, routes depend on the removed nexthop are
already removed. It is not necessary to remove them, as already
commented. Let's forget them without trying to remove.
Previously, even if KeepConfiguration=dhcp or yes is specified in the
new .network file, dynamic configurations like DHCP address and routes
were dropped when 'networkctl reconfigure INTERFACE' is invoked.
If the setting is specified, let's gracefully handle the dynamic
configurations. Then, 'networkctl reconfigure' can be also used for
an interface that has critical connections.

Unnecessary static configs will be anyway dropped later in
link_configure() -> link_drop_unmanaged_config(). Hence, even if we are
reconfiguring an interface cleanly, it is not necessary to drop static
configs here.
Unreachable routes are not owned by any interfaces, and its ifindex is
zero. Previously, if a non-upstream interface is reconfigured, all routes
including unreachable routes configured by the upstream interface are
removed.
This makes unreachable routes are always handled by the upstream interface,
and only removed when the delegated prefixes are changed or lost.

With the commits, reloading .network files does not release previously
acquired DHCP lease and friends if possible.
On graceful reconfigure triggered by the reload, the interface may
acquire a new DHCPv4 lease earlier than DHCPv6 lease. In that case,
the check will fail as it is done with the new DHCPv4 lease and old
DHCPv6 lease, which does not contain any IPv6 DNS servers or so.
So, when switching from no -> yes, we need to wait a new lease with DNS
servers or so. To achieve that, we need to clean reconfigure the interface.
Follow-up for 451c2baf30.
With the commits, reloading .network files does not release previously
acquired DHCP lease and friends if possible. If previously a DHCP client
was configured as not requesting DNS servers or so, then the previously
acquired lease might not contain any DNS servers. In that case, if the
new .network file enables UseDNS=, then the interface should enter the
configured state after a new lease is acquired. To achieve that, we need
to reset the flags.
With this change, the workaround applied to the test by the commit
451c2baf30 can be dropped.
Otherwise, even if a link enters the configuring state at the beginning
of link_configure(), link_check_ready() may be called before
link_drop_unmanaged_config() is called, and the link may enter the
configured state.
Fixes#35092.
`loginctl kill-session --kill-whom=leader <N>` (or the D-Bus equivalent)
doesn't work because logind ends up calling `KillUnit(..., "main", ...)`
on a scope unit and these don't have a `MainPID` property. Here, I just
make it send a signal to the `Leader` directly.
Fixes a couple of bugs with systemd-sysupdated's target enumeration. See
commit messages for details.

To keep align with the logic used in udev_rules_parse_file(), we also
should skip the empty udev rules file while collecting the stats during
manager reload. Otherwise all udev rules files will be parsed again whenever
reloading udev manager with an empty udev rules file. It's time consuming
and the following uevents will fail with timeout.
A bit confusingly CONTAINER_UID_BASE_MAX is just the maximum *base* UID
for a container. Thus, with the usual 64K UID assignments, the last
actual container UID is CONTAINER_UID_BASE_MAX+0xFFFF.
To make this less confusing define CONTAINER_UID_MIN/MAX that add the
missing extra space.
Also adjust two uses where this was mishandled so far, due to this
confusion.
With this change the UID ranges we default to should properly match what
is documented on https://systemd.io/UIDS-GIDS/.

In the troff output, this doesn't seem to make any difference. But in the
html output, the whitespace is sometimes preserved, creating an additional
gap before the following content. Drop it everywhere to avoid this.
