Remove generated controls.conf file from system tests
The controls.conf file shouldn't be used directly without templating it
first. Remove this no longer used hard-coded file to avoid confusion.

Revive dupsigs system test
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.

Revive the stress system test
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
seem to run too long or interfere with other tests any more (the
original note claiming so is more than 20 years old).

Revive dialup system test
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).

Make digdelv test work in different network envs
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.

Remove the time requirement for the statschannel truncated test
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.

Add tests for CVE-2022-2795
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.

Remove system test delzone
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.

doth system test: increase transfers-in/out limits
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.

doth system test - decrease HTTP listener quota size
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.

9bfb9184f2 Fix startup detection after restart in start.pl
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.

2584413c90 Do not truncate ns2 logs in the "rrsetorder" test
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.

35e37505f0 Fix RRL responses-per-second bypass using wildcard names
It is possible to bypass Response Rate Limiting (RRL)
`responses-per-second` limitation using specially crafted wildcard
names, because the current implementation, when encountering a found
DNS name generated from a wildcard record, just strips the leftmost
label of the name before making a key for the bucket.

While that technique helps with limiting random requests like
<random>.example.com (because all those requests will be accounted
as belonging to a bucket constructed from "example.com" name), it does
not help with random names like subdomain.<random>.example.com.

The best solution would have been to strip not just the leftmost
label, but as many labels as necessary until reaching the suffix part
of the wildcard record from which the found name is generated, however,
we do not have that information readily available in the context of RRL
processing code.

Fix the issue by interpreting all valid wildcard domain names as
the zone's origin name concatenated to the "*" name, so they all will
be put into the same bucket.

d1315d1bc4 Update inline system test, zone 'retransfer3.'
The zone 'retransfer3.' tests whether zones that 'rndc signing
-nsec3param' requests are queued even if the zone is not loaded.

The test assumes that if 'rndc signing -list' shows that the zone is
done signing with two keys, and there are no NSEC3 chains pending, the
zone is done handling the '-nsec3param' queued requests. However, it
is possible that the 'rndc signing -list' command is received before
the corresponding privatetype records are added to the zone (the records
that are used to retrieve the signing status with 'rndc signing').

This is what happens in test failure
https://gitlab.isc.org/isc-projects/bind9/-/jobs/2722752.

The 'rndc signing -list retransfer3' is thus an unreliable check.
It is simpler to just remove the check and wait for a certain amount
of time and check whether ns3 has re-signed the zone using NSEC3.

73431eef8f Add test case for #3486
Add two scenarios where we change the dnssec-policy from using RSASHA1
to something with NSEC3.

The first case should work, as the DS is still in hidden state and we
can basically do anything with DNSSEC.

The second case should fail, because the DS of the predecessor is
published and we can't immediately remove the predecessor DNSKEY. So
in this case we should keep the NSEC chain for a bit longer.

Add two more scenarios where we change the dnssec-policy from using
NSEC3 to something NSEC only. Both should work because there are no
restrictions on using NSEC when it comes to algorithms, but in the
cases where the DS is published we can't bluntly remove the predecessor.

Extend the nsec3 system test by also checking the DNSKEY RRset for the
expected DNSKEY records. This requires some "kasp system"-style setup
for each test (setting key properties and key states). Also move the
dnssec-verify check inside the check_nsec/check_nsec3 functions because
we will have to do that every time.

c652c94024 autosign: use FIPS compatible algorithms and key sizes
The nsec-only.example zone was not converted as we use it to
test nsec-only DNSSEC algorithms to nsec3 conversion failure.
The subtest is skipped in fips mode.

Update "checking revoked key with duplicate key ID" test
to use FIPS compatible algorithm.
