Fabian Henneke 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.

Fixes: #11996.

Luca Boccassi 65224c1d0e core: rename ShutdownWatchdogSec to RebootWatchdogSec 
This option is only used on reboot, not on other types of shutdown
modes, so it is misleading.
Keep the old name working for backward compatibility, but remove it
from the documentation.

Luca Boccassi acafd7d8a6 core: add KExecWatchdogSec option 
Rather than always enabling the shutdown WD on kexec, which might be
dangerous in case the kernel driver and/or the hardware implementation
does not reset the wd on kexec, add a new timer, disabled by default,
to let users optionally enable the shutdown WD on kexec separately
from the runtime and reboot ones. Advise in the documentation to
also use the runtime WD in conjunction with it.

Fixes: a637d0f9ec ("core: set shutdown watchdog on kexec too")

Jan Klötzke 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.

Susant Sahani 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.

Clemens Gruber c423be28a0 network: introduce TripleSampling= option in CAN section 
When enabled, three samples are used to determine the value of a

This patch adds support for the TripleSampling= option in the [CAN]
section of .network files.

Zbigniew Jędrzejewski-Szmek c448459d56 networkd: refuse more than 128 NTP servers 
This test case is a bit silly, but it shows that our code is unprepared to
handle so many network servers, with quadratic complexity in various places.
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.

Zbigniew Jędrzejewski-Szmek 95b2903bde tests: shorten the fuzz test case 
The test was failing in Ubuntu CI with a 30s timeout. It makes
sense to keep the file so exercise the set allocation logic, but
we can make it shorter.

Zbigniew Jędrzejewski-Szmek 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.

Zbigniew Jędrzejewski-Szmek ea53cfd195 shared/calendarspec: do not allocate a big string on stack 
The string can be as long as a logical line in a unit file — so no unlimited,
but quite big. Let's use a normal heap allocation when making a copy.
