If named is configured to perform DNSSEC validation and also forwards
all queries ("forward only;") to validating resolvers, negative trust
anchors do not work properly because the CD bit is not set in queries
sent to the forwarders. As a result, instead of retrieving bogus DNSSEC
material and making validation decisions based on its configuration,
named is only receiving SERVFAIL responses to queries for bogus data.
Fix by ensuring the CD bit is always set in queries sent to forwarders
if the query name is covered by an NTA.

there is now a common list of tests in conf.sh.common, with the
tests that are either unique to windows or to unix, or which are
enabled or disabled by configure or Configure, being listed in
separate variables in conf.sh.in and conf.sh.win32.

this moves the creation of "parallel.mk" into a separate shell script
instead of bin/tests/system/Makefile. that shell script can now be
executed by runall.sh, allowing us to make use of the cygwin "make"
command, which supports parallel execution.

Windows systems do not allow a trailing period in file names while Unix
systems do. When BIND system tests are run, the $TP environment
variable is set to an empty string on Windows systems and to "." on Unix
systems. This environment variable is then used by system test scripts
for handling this discrepancy properly.
In multiple system test scripts, a variable holding a zone name is set
to a string with a trailing period while the names of the zone's
corresponding dlvset-* and/or dsset-* files are determined using
numerous sed invocations like the following one:
dlvsets="$dlvsets dlvset-`echo $zone |sed -e "s/.$//g"`$TP"
In order to improve code readability, use zone names without trailing
periods and replace sed invocations with variable substitutions.
To retain local consistency, also remove the trailing period from
certain other zone names used in system tests that are not subsequently
processed using sed.

In the "allow-query" system test, ns3 uses a root hints file which
contains a single entry for a.root-servers.nil (10.53.0.1). This name
is not present in the root zone served by ns1, which means querying it
for that name and any type will yield an NXDOMAIN response. When
combined with unfavorable thread scheduling, this can lead to ns3
caching an NXDOMAIN response for the only root server it is aware of and
thus to false positives for the "allow-query" system test caused by ns3
returning unexpected SERVFAIL responses. Fix by modifying the root zone
served by ns1 so that authoritative responses to a.root-servers.nil
queries match the root hints file used by ns3.

Key IDs may accidentally match dig output that is not the key ID (for
example the RRSIG inception or expiration time, the query ID, ...).
Search for key ID + signer name should prevent that, as that is what
only should occur in the RRSIG record, and signer name always follows
the key ID.

Remove sleep calls from test, rely on wait_for_log(). Make
wait_for_log() and dnssec_loadkeys_on() fail the test if the
appropriate log line is not found.
Slightly adjust the echo_i() lines to print only the key ID (not the
key name).

One second may not be enough for an NSEC3 chain change triggered by an
UPDATE message to complete. Wait up to 10 seconds when checking whether
a given NSEC3 chain change is complete in the "nsupdate" system test.

In the "nsupdate" system test, do not sleep before checking results of
changes which are expected to be processed synchronously, i.e. before
nsupdate returns.

Make bin/tests/system/ifconfig.bat also configure addresses ending with
9 and 10, so that the script is in sync with its Unix counterpart.
Update comments listing the interfaces created by ifconfig.{bat,sh} so
that they do not include addresses whose last octet is zero (since an
address like 10.53.1.0/24 is not a valid host address and thus the
aforementioned scripts do not even attempt configuring them).

On Windows, the bin/tests/system/dnssec/signer/example.db.signed file
contains carriage return characters at the end of each line. Remove
them before passing the aforementioned file to the awk script extracting
key IDs so that the latter can work properly.

As signals are currently not handled by named on Windows, instances
terminated using signals are not able to perform a clean shutdown, which
involves e.g. removing the lock file. Thus, waiting for a given
instance's lock file to be removed beforing assuming it is shut down
is pointless on Windows, so do not even attempt it.
(cherry picked from commit 761ba4514f)
When a Windows service receives a request to stop, it should not set its
state to SERVICE_STOPPED until it is completely shut down as doing that
allows the operating system to kill that service prematurely, which in
the case of named may e.g. prevent the PID file and/or the lock file
from being cleaned up.
Set service state to SERVICE_STOP_PENDING when named begins its shutdown
and only report the SERVICE_STOPPED state immediately before exiting.

This tests both the cases when the DLV trust anchor is of an
unsupported or disabled algorithm, as well as if the DLV zone
contains a key with an unsupported or disabled algorithm.
(cherry picked from commit 3b7c849a3f)
Some values returned by dstkey_fromconfig() indicate that key loading
should be interrupted, others do not. There are also certain subsequent
checks to be made after parsing a key from configuration and the results
of these checks also affect the key loading process. All of this
complicates the key loading logic.
In order to make the relevant parts of the code easier to follow, reduce
the body of the inner for loop in load_view_keys() to a single call to a
new function, process_key(). Move dstkey_fromconfig() error handling to
process_key() as well and add comments to clearly describe the effects
of various key loading errors.

More specifically: ignore configured trusted and managed keys that
match a disabled algorithm. The behavioral change is that
associated responses no longer SERVFAIL, but return insecure.

Move from conf.sh.in to conf.sh.common as they will also need to be

this restores functionality that was removed in commit 03be5a6b4e,
allowing named to search in authoritative zone databases outside the
current zone for additional data, if and only if recursion is allowed
and minimal-responses is disabled.

This commit adds a lengthy test where the ZSK is rolled but the
KSK is offline (except for when the DNSKEY RRset is changed). The
specific scenario has the `dnskey-kskonly` configuration option set
meaning the DNSKEY RRset should only be signed with the KSK.
A new zone `updatecheck-kskonly.secure` is added to test against,
that can be dynamically updated, and that can be controlled with rndc
to load the DNSSEC keys.
There are some pre-checks for this test to make sure everything is
fine before the ZSK roll, after the new ZSK is published, and after
the old ZSK is deleted. Note there are actually two ZSK rolls in
quick succession.
When the latest added ZSK becomes active and its predecessor becomes
inactive, the KSK is offline. However, the DNSKEY RRset did not
change and it has a good signature that is valid for long enough.
The expected behavior is that the DNSKEY RRset stays signed with
the KSK only (signature does not need to change). However, the
test will fail because after reconfiguring the keys for the zone,
it wants to add re-sign tasks for the new active keys (in sign_apex).
Because the KSK is offline, named determines that the only other
active key, the latest ZSK, will be used to resign the DNSKEY RRset,
in addition to keeping the RRSIG of the KSK.
The question is: Why do we need to resign the DNSKEY RRset
immediately when a new key becomes active? This is not required,
only once the next resign task is triggered the new active key
should replace signatures that are in need of refreshing.
(cherry picked from commit 8bc10bcf59)
Some system tests assume dig's default setings are in effect. While
these defaults may only be silently overridden (because of specific
options set in /etc/resolv.conf) for BIND releases using liblwres for
parsing /etc/resolv.conf (i.e. BIND 9.11 and older), it is arguably
prudent to make sure that tests relying on specific +timeout and +tries
settings specify these explicitly in their dig invocations, in order to
prevent test failures from being triggered by any potential changes to
current defaults.

This changes dns_dtdata struct to not expose data types from dnstap.pb-c.h to
prevent the need for including this header where not really needed.
(cherry picked from commit 8ccce7e24b)
Simply looking for the key ID surrounded by spaces in the tested
dnssec-signzone output file is not a precise enough method of checking
for signatures prepared using a given key ID: it can be tripped up by
cross-algorithm key ID collisions and certain low key IDs (e.g. 60, the
TTL specified in bin/tests/system/dnssec/signer/example.db.in), which
triggers false positives for the "dnssec" system test. Make key ID
extraction precise by using an awk script which operates on specific
fields.
(cherry picked from commit a40c60e4c1)
The "mirror" system test expects all dig queries (including recursive
ones) to be responded to within 1 second, which turns out to be overly
optimistic in certain cases and leads to false positives being
triggered. Increase dig query timeout used throughout the "mirror"
system test to 2 seconds in order to alleviate the issue.
(cherry picked from commit 73afbdc552)
Currently, ns3 in the "mirror" system test sends trust anchor telemetry
queries every second as it is started with "-T tat=1". Given the number
of trust anchors configured on ns3 (9), TAT-related traffic clutters up
log files, hindering troubleshooting efforts. Increase TAT query
interval to 3 seconds in order to alleviate the issue.
Note that the interval chosen cannot be much higher if intermittent test
failures are to be avoided: TAT queries are only sent after the
configured number of seconds passes since resolver startup. Quick
experiments show that even on contemporary hardware, ns3 should be
running for at least 5 seconds before it is first shut down, so a
3-second TAT query interval seems to be a reasonable, future-proof
compromise. Ensure the relevant check is performed before ns3 is first
shut down to emphasize this trade-off and make it more clear by what
time TAT queries are expected to be sent.
