fcc1d0315d basic/set: add set_ensure_consume() 
This combines set_ensure_allocated() with set_consume(). The cool thing is that
because we know the hash ops, we can correctly free the item if appropriate.
Similarly to set_consume(), the goal is to simplify handling of the case where
the item needs to be freed on error and if already present in the set.

2a71d57f4e network: clean-up DHCP lease server data configuration 
This is an attempt to clean up the POP3/SMTP/LPR/… DHCP lease server
data logic in networkd. This reduces code duplication and fixes a number
of bugs.

This removes any support for collecting POP3/SMPT/LPR servers acquired
via local DHCP client releases since noone uses that, and given how old
these protocols are I doubt this will change. It keeps support for
configuring them for the dhcp server however.

The differences between the DNS/NTP/SIP/POP3/SMTP/LPR configuration
logics are minimized.

This removes the relevant symbols from sd-network.h (which is an
internal API only at this point after all).

This is unfortunately not well test, given the old code for this had
barely any tests. But the new code should not perform worse at least,
and allow us to release, since it corrects some interfaces visible in
the .network configuration format.

Fixes: #15943

9efa8a3cff network: DHCPv6 Assign delegated prefix to LAN interface 
In DHCPv6-PD environment, where WAN interface requests IPv6 via DHCPv6,
receives the address as well as delegated prefixes, with LAN interfaces
serving those delegated prefixes in their router advertisement messages.
The LAN interfaces on the router themselves do not have
the IPv6 addresses assigned by networkd from the prefix it
serves on that interface. Now this patch enables it.

networkd: Add support for setting a preferred subnet id for IPv6 PD leases 
This allows users to configure a subnet id that should be used instead
of automatically (sequentially) assigned subnets. The previous attempt
had the downside that the subnet id would not be the same between
networkd restarts. In some setups it is desirable to have predictable
subnet ids across restarts of services and systems.

The code for the assignment had to be broken up into two pieces. One of
them is the old (sequential) assignment of prefixes and the other is the
new assignment based on configured subnet ids. The new assignment code
has to be executed first and has to be taken into account when (later
on) allocating the "old" subnets from the same pool.

Instead of having one iteration through the links we are now trying to
allocate a prefix for every link on every delegated prefix, unless they
received an assignment in a previous iteration.

7354900ddd network: Fix split in SendOption= on client and server 
When specifying `DHCPv4.SendOption=`, it is used by systemd-networkd to
set the value of that option within the DHCP request that is sent out.
This differs to setting `DHCPServer.SendOption=`, which will place all
the options together as suboptions into the vendor-specific information
(code 43) option.

This commit adds two new config options, `DHCPv4.SendVendorOption=` and
`DHCPServer.SendVendorOption=`. These both have the behaviour of the old
`DHCPServer.SendOption=` flag, and set the value of the suboption in the
vendor-specific information option.

The behaviour of `DHCPServer.SendOption=` is then changed to reflect
that of `DHCPv4.SendOption=`. It will set the value of the corresponding
option in the DHCP request.

864edb39cf network: rename SendOptions= to SendOption= 
The name with plural made more sense where multiple options could be specified
in one line. After changes in the pull request, this option only accepts one
value, so from users' POV it should be singular.

(The field in the data structure remains plural, because it actually stores
multiple values.)

9ed7de605d scope: Support RuntimeMaxSec= directive in scope units 
Just as `RuntimeMaxSec=` is supported for service units, add support for
it to scope units. This will gracefully kill a scope after the timeout
expires from the moment the scope enters the running state.

This could be used for time-limited login sessions, for example.

afe42aef39 dhcp4: make IPServiceType configurable 
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.

Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.

d45ee2f31a udev: Add id program and rule for FIDO security tokens 
Add a fido_id program meant to be run for devices in the hidraw
subsystem via an IMPORT directive. The program parses the HID report
descriptor and assigns the ID_SECURITY_TOKEN environment variable if a
declared usage matches the FIDO_CTAPHID_USAGE declared in the FIDO CTAP
specification. This replaces the previous approach of whitelisting all
known security token models manually.

This commit is accompanied by a test suite and a fuzzer target for the
descriptor parsing routine.

from the runtime and reboot ones. Advise in the documentation to

DF is configured to be inherited, always set it.

dc653bf487 service: handle abort stops with dedicated timeout 
When shooting down a service with SIGABRT the user might want to have a
much longer stop timeout than on regular stops/shutdowns. Especially in
the face of short stop timeouts the time might not be sufficient to
write huge core dumps before the service is killed.

This commit adds a dedicated (Default)TimeoutAbortSec= timer that is
used when stopping a service via SIGABRT. In all other cases the
existing TimeoutStopSec= is used. The timer value is unset by default
to skip the special handling and use TimeoutStopSec= for state
'stop-watchdog' to keep the old behaviour.

If the service is in state 'stop-watchdog' and the service should be
stopped explicitly we still go to 'stop-sigterm' and re-apply the usual
TimeoutStopSec= timeout.

81962db798 network: Introduce MACsec 
Media Access Control Security (MACsec) is an 802.1AE IEEE
industry-standard security technology that provides secure
communication for all traffic on Ethernet links.
MACsec provides point-to-point security on Ethernet links between
directly connected nodes and is capable of identifying and preventing
most security threats, including denial of service, intrusion,
man-in-the-middle, masquerading, passive wiretapping, and playback attacks.

c448459d56 networkd: refuse more than 128 NTP servers 
This test case is a bit silly, but it shows that our code is unprepared to

I don't think there are any valid reasons to have hundres of NTP servers
configured, so let's just emit a warning and cut the list short.

5e2a51d588 networkd: use OrderedSets instead of strvs to store lists of domains 
We were already using OrderedSets in the manager object, but strvs in the
configuration parsing code. Using sets gives us better scaling when many
domains are used.

In oss-fuzz #13059 the attached reproducer takes approximately 30.5 s to be
parsed. Converting to sets makes this go down to 10s. This is not _vastly_
faster, but using sets seems like a nicer approach anyway. In particular, we
avoid the quadratic de-unification operation after each addition.

93b4dab57e networkd: Allow to retain configs even if carrier is lost 
When there is bad link in the network the carrier goes up/down.
This makes networkd stops all the clients and drop config.
But if the remote router/dhcpserver running a prevention
of DHCP Starvation attack or DHCP Flood attack it does not allow
networkd to take a DHCP lease resulting failure in configuration.
This patch allows to keep the client running and keep the conf
also for this scenario.
