serve stale feature to keep the DNS resource records beyond TTL to return them as stale records in case of upstream server is not reachable or returns negative response.
SD_RESOLVED_NO_STALE flag has been added to disable serving stale records via dbus.
added serve stale test cases to TEST-75-RESOLVED
Fixes: #21815
From changelog of dnsmasq v2.87:
====
Note in manpage the change in behaviour of -address. This behaviour
actually changed in v2.86, but was undocumented there. From 2.86 on,
(eg) --address=/example.com/1.2.3.4 ONLY applies to A queries. All other
types of query will be sent upstream. Pre 2.86, that would catch the
whole example.com domain and queries for other types would get
a local NODATA answer. The pre-2.86 behaviour is still available,
by configuring --address=/example.com/1.2.3.4 --local=/example.com/
====
This makes a bond or bridge interface in the degraded-carrier state but has a routable address
handled as routable operational state.
If the carrier is degraded but the address state is routable then the operational state should be
seen as routable and not degraded because that may be the case for bonds if some of the links are down,
but when that happens the bond as whole is still routable.
This also makes operational state to degraded if address state is degraded even if the link state is
degraded-carrier.
Fixes#22713.
Let's take a step back and revert back to the original behavior where we
exit on a first failing subtest. The current behavior makes fishing out the
failing test details quite unpleasant, and in certain situations the
journal may even be rotated away so we end up with no actionable logs.
The test was originally introduced for Ubuntu CI, as it uses
PREFER_NSPAWN=1, but it was subsequently disabled two years ago [0], so
it was pretty much useless. Let's merge it into TEST-02 and tweak it a
bit to run only certain tests under QEMU when $TEST_PREFER_NSPAWN is
set.

The kernel command line may contain newlines which kernel happily
accepts, but we'd ignore everything past the first newline. Let's fix
that by replacing read_one_line_file() with read_full_file().
ImportCredential= takes a credential name and searches for a matching
credential in all the credential stores we know about it. It supports
globs which are expanded so that all matching credentials are loaded.
With these settings we intend to turn off timeouts for possibly
interactive/slow commands. The officially documented way to turn off the
time-outs is to setting them to infinity. So far we set them to zero
here though.
This lead to some confusiong, for example #18224. Let's fix this by
uniformly spelling out TimeoutSec=infinity.
This doesn't change behaviour. It just makes our generated files match
what we document, without relying on historic compat support.
Fixes: #18224
Turns out we can, apart from just building the module, "shove" it into
the SELinux database in a chroot as well. This brings quite significant
time savings, as the SELinux db rebuild takes 2 - 5 minutes in a VM
without acceleration (and takes currently ~half of the runtime of the test
in the C8S job).
