The changes in the code have the side effect that the CDNSKEY and CDS
records in the secure version of the zone are not reusable and thus
are thrashed from the zone. Remove the apex checks for this use case.
We only care about that the zone is not immediately goes bogus, but
a user really should use the built-in "insecure" policy when unsigning
a zone.

Similar to an attempt to add NSEC through dynamic update, add a test
case that tries to add NSEC3 through zone transfer.
(cherry picked from commit ef1cb9935c)
Add one more case that tests reconfiguring a zone to turn off
inline-signing. It should still be a valid DNSSEC zone and the NSEC3
parameters should not change.
Add another test to ensure that you cannot update the zone with a
NSEC3 record.
(cherry picked from commit 4cd8e8e9c3)
We no longer accept copying DNSSEC records from the raw zone to
the secure zone, so update the kasp system test that relies on this
accordingly.
Also add more debugging and store the dnssec-verify results in a file.
(cherry picked from commit 57ea9e08c6)
Add a kasp system test that reconfigures a dnssec-policy zone from
maintaining DNSSEC records directly to the zone to using inline-signing.
Add a similar test case to the nsec3 system test, testing the same
thing but now with NSEC3 in use.
(cherry picked from commit 9018fbb205)
Add a dnssec test to make sure that named can correctly process a
managed-keys zone with a placeholder KEYDATA record.
(cherry picked from commit 8c48eabbc1)
the dupsigs test is prone to failing on slow CI machines

Use the ALGORITHM_SET option to use randomly selected default algorithm
in this test. Make sure the test works by using variables instead of
hard-coding values.
(cherry picked from commit f65f276f98)
Use the get_algorithms.py script to detect supported algorithms and
select random algorithms to use for the tests.
Make sure to load common.conf.sh after KEYGEN env var is exported.
(cherry picked from commit 69b608ee9f)
Multiple algorithm sets can be defined in this script. These can be
selected via the ALGORITHM_SET environment variable. For compatibility
reasons, "stable" set contains the currently used algorithms, since our
system tests need some changes before being compatible with randomly
selected algorithms.
The script operation is similar to the get_ports.py - environment
variables are created and then printed out as `export NAME=VALUE`
commands, to be interpreted by shell. Once we support pytest runner for
system tests, this should be a fixture instead.
(cherry picked from commit 5f480c8485)
Certain variables have to be exported in order for the system tests to
work. It makes little sense to export the variables in one place/script
while they're defined in another place.
Since it makes no harm, export all the variables to make the behaviour
more predictable and consistent. Previously, some variables were
exported as environment variables, while others were just shell
variables which could be used once the configuration was sourced from
another script. However, they wouldn't be exposed to spawned processes.
For simplicity sake (and for the upcoming effort to run system tests
with pytest), export all variables that are used. TESTS, PARALLEL_UNIX
and SUBDIRS variables are automake-specific, aren't used anywhere else
and thus not exported.
(cherry picked from commit 37d14c69c0)
The only variable really needed for the script to work is the path to
the $KEYGEN binary. Allow setting this via an environment variable to
avoid loading conf.sh (and causing a chicken-egg problem). Also make
testcrypto.sh executable to allow its use from conf.sh.

Add a test case that if the first primary fails, the fallback of a
second primary on plain DNS works. This is mainly to test that the port
configuration inheritance works correctly.

Add a couple of tests that verify the serve-stale behavior when

The test triggers a prefetch, but fails to check if it acutally
happened, which prevented it from catching a bug when the record's
TTL value matches the configured prefetch eligibility value.
Check that prefetch happened by comparing the TTL values.

For tests where the TCP connection might get interrupted abruptly,
replace the nc with curl as the data sent from server to client might
get lost because of abrupt TCP connection. This happens when the TCP
connection gets closed during sending the large request to the server.
As we already require curl for other system tests, replace the nc usage
in the statschannel test with curl that actually understands the
HTTP/1.1 protocol, so the same connection is reused for sending the
consequtive requests, but without client-side "pipelining".
For the record, the server doesn't support parallel processing of the
pipelined request, so it's a bit misnomer here, because what we are
actually testing is that we process all requests received in a single
TCP read callback.
(cherry picked from commit cd0e5c5784)
Now that the artificial limit on the recv buffer has been removed, the
current system test always fails because it tests if the truncation has
happened.
Add test that sending more than 10 headers makes the connection to
closed; and add test that sending huge HTTP request makes the connection
to be closed.

The controls.conf file shouldn't be used directly without templating it

Correctly source conf.sh in dupsigs test scripts (fix issue introduced
by 093af1c00a).
Update dupsigs test for dnssec-dnskey-kskonly default. Since v9.17.20,
the dnssec-dnskey-kskonly is set to yes. Update the test to not expect
the additional RRSIG with ZSK for DNSKEY.
Speed up the test from 20 minutes to 2.5 minutes and make it part of the
default test suite executed in CI.
- decrease number of records to sign from 2000 to 500
- decrease the signing interval by a factor of 6
- shorten the final part of the test after last signing (since nothing
new happens there)
Finally, clarify misleading comments about (in)sufficient time for zone
re-signing. The time used in the test is in fact sufficient for the
re-signing to happen. If it wasn't, the previous ZSK would end up being
deleted while its signatures would still be present, which is a
situation where duplicate signatures can still happen.

Ensure the port numbers are dynamically filled in with copy_setports.
Clarify test fail condition.
Make the stress test part of the default test suite since it doesn't

Properly template the port number in config files with copy_setports.
The test takes two minutes on my machine which doesn't seem like a
proper justification to exclude it from the test suite, especially
considering we run these tests in parallel nowadays. The resource usage
doesn't seems significantly increased so it shouldn't interfere with
other system tests.
There also exists a precedent for longer running system tests that are
already part of the default system test suite (e.g. serve-stale takes
almost three minutes on the same machine).
(cherry picked from commit 235ae5f344)
When a target server is unreachable, the varying network conditions may
cause different ICMP message (or no message). The host unreachable
message was discovered when attempting to run the test locally while
connected to a VPN network which handles all traffic.
Extend the dig output check with "host unreachable" message to avoid a
false negative test result in certain network environments.
(cherry picked from commit 1e7d832342)
The 5 seconds requirement to finish the 'pipelined with truncated
stream' was causing spurious failures in the CI because the job runners
might be very busy and sending 128k of data might simply take some time.
Remove the time requirement altogether, there's actually no reason why
the test SHOULD or even MUST finish under 5 seconds.
(cherry picked from commit 0f56a53d66)
Add a test ensuring that the amount of work fctx_getaddresses() performs
for any encountered delegation is limited: delegate example.net to a set
of 1,000 name servers in the redirect.com zone, the names of which all
resolve to IP addresses that nothing listens on, and query for a name in
the example.net domain, checking the number of times the findname()
function gets executed in the process; fail if that count is excessively
large.
Since the size of the referral response sent by ans3 is about 20 kB, it
cannot be sent back over UDP (EMSGSIZE) on some operating systems in
their default configuration (e.g. FreeBSD - see the
net.inet.udp.maxdgram sysctl). To enable reliable reproduction of
CVE-2022-2795 (retry patterns vary across BIND 9 versions) and avoid
false positives at the same time (thread scheduling - and therefore the
number of fetch context restarts - vary across operating systems and
across test runs), extend bin/tests/system/resolver/ans3/ans.pl so that
it also listens on TCP and make "ns1" in the "resolver" system test
always use TCP when communicating with "ans3".
Also add a test (foo.bar.sub.tld1/TXT) that ensures the new limitations
imposed on the resolution process by the mitigation for CVE-2022-2795 do
not prevent valid, glueless delegation chains from working properly.

There are multiple reasons to remove this test as obsolete:
- The test may not possibly work for over 2.5 years, since
98b3b93791 removed the rndc.py python
tool on which this test relies.
- It isn't part of the test suite either in CI or locally unless it is
explicitly enabled. As a result, there are many issues which prevent
the test from being executed caused by various refactoring efforts
accumulated over time.
- Even if the test could be executed, it has no clear failure condition.
If the python script(s) fail, the test still passes.
(cherry picked from commit 05180154d9)
Sometimes doth test could intermittently fail shortly after start due
to inability to complete a zone transfer in time. As it turned out, it
could happen due to transfers-in/out limits. Initially the defaults
were fine, but over time, especially when adding Strict/Mutual TLS, we
added more than 10 zones so it became possible to hit the limits.
This commit takes care of that by bumping the limits.
(cherry picked from commit 95a551de7b)
This commit reduces the size of HTTP listener quota from 300 (default)
to 100 so that it would make hitting any global limits in case of
running multiple tests in parallel in multiple containers unlikely.
This way the need in opening many file descriptors of different
kinds (e.g. client side connections and pipes) gets significantly
reduced while the required code paths are still verified.
(cherry picked from commit 354494cd10)
The bin/tests/system/start.pl script waits until a "running" message is
logged by a given name server instance before attempting to send a
version.bind/CH/TXT query to it. The idea behind this was to make the
script wait until named loads all the zones it is configured to serve
before telling the system test framework that a given server is ready to
use; this prevents the need to add boilerplate code that waits for a
specific zone to be loaded to each test expecting that.
The problem is that when it looks for "running" messages, the
bin/tests/system/start.pl script assumes that the existence of any such
message in the named.run file indicates that a given named instance has
already finished loading all zones. Meanwhile, some system tests
restart all the named instances they use throughout their lifetime (some
even do that a few times), for example to run Python-based tests. The
bin/tests/system/start.pl script handles such a scenario incorrectly: as
soon as it finds any "running" message in the named.run file it inspects
and it gets a response to a version.bind/CH/TXT query, it tells the
system test framework that a given server is ready to use, which might
not be true - it is possible that only the "version.bind" zone is loaded
at that point and the "running" message found was logged by a
previously-shutdown named instance. This triggers intermittent failures
for Python-based tests.
Fix by improving the logic that the bin/tests/system/start.pl script
uses to detect server startup: check how many "running" lines are
present in a given named.run file before attempting to start a named
instance and only proceed with version.bind/CH/TXT queries when the
number of "running" lines found in that named.run file increases after
the server is started.
(cherry picked from commit 18e20f95f6)
In the "rrsetorder" system test, the ns2 named instance is restarted
without passing the --restart option to bin/tests/system/start.pl. This
causes the log file for that named instance to be needlessly truncated.
Prevent this from happening by restarting the affected named instance
in the same way as all the other named instances used in system tests.

If there are duplicate key ids across multiple algorithms expected
output is no met. We have fixed this in on main but decided to not
