networkd-test: use a complete domain name in test_route_only_dns()
Since version 241 (commit ea4678?), querying MX type records for
single-label domains does not actually forward the query to the DNS
server any more. Use "example.com" instead, which is the recommended
test domain anyway.

networkd-test: disable DNSSEC in domain-restricted DNS test
dnsmasq 2.80 changed behaviour when being queried by resolved with
enabled DNSSEC: It returns errors for SOA and DS queries which cause the
entire query to fail. As we don't configure DNSSEC in this test anyway,
just disable it so that we retain compatibility with old and new dnsmasq
versions.
Before a3ce813697bcc1c4644e097a2f1cd0459326d6ee, all properties in
src->properties and src->properties_db are mixed and copied to
dst->properties_db by device_copy_properties().
So, it is not necessary to store data from udev database file to
sd_device::properties_db before copying properties.
But now, properties are not mixed. So, the read data need to be
stored to also ::properties_db.

sd-bus: enforce a size limit on D-Bus object paths
Replace stack with heap allocation. This avoids accessing/modifying
memory outside of the allocated stack region by sending specially
crafted D-Bus messages with very large object paths.

systemd (241-7~deb10u7) buster; urgency=medium
* core: make sure to restore the control command id, too.
Fixes a segfault in systemd that can be triggered when both
daemon-reload and a service restart happen concurrently. (Closes: #984495)
* seccomp: allow turning off of seccomp filtering via env var.
Since glibc 2.33 faccessat() is implemented via faccessat2(), which
is breaking running containers that use such a version of glibc under
systemd-nspawn in Buster.
Turning off seccomp filtering via the SYSTEMD_SECCOMP env var makes it
possible to run such new containers. (Closes: #984573)
