Add a test to check that the timed out responses do not skew the
normal responses statistics counters, and that they do update the
timeouts counter.

When -T cookiealwaysvalid is passed to named, DNS cookie checks for
the incoming queries always pass, given they are structurally correct.
(cherry picked from commit 807ef8545d)
The 'I:checking that lifting the limit will allow everything to get
cached (20)' test was failing due to the TTL of the records being
too short for the elapsed time of the test. Raise the TTL to fix
this and adjust other tests as needed.
(cherry picked from commit 1a58bd2113)
when running a system test with the USE_RR environment
variable set to 1, an rr trace is generated for named.
because rr wasn't run using libtool --mode=execute, the
trace would actually be generated for the wrapper script
generated by libtool, not for the actual named binary.

add a zone with different NS RRsets in the parent and child,
and test resolver and forwarder behavior with and without +CD.
(cherry picked from commit e4652a0444)
If a deferred validation on data that was originally queried with
CD=1 fails, we now repeat the query, since the zone data may have
changed in the meantime.

In #1870, the expiration time of ANCIENT records were printed, but
actually the ancient records are very short lived, and the information
carries a little value.
Instead of printing the expiration of ANCIENT records, print the
expiration time of STALE records.
The ANS servers were not to written to handle NS queries at the
QNAME resulting in gratuitious protocol errors that will break tests
when NS requests are made for the QNAME.
(cherry picked from commit 0680eb6f64)
When the header has been marked as ANCIENT, but the ttl hasn't been
reset (this happens in couple of places), the rdataset TTL would be
set to the header timestamp instead to a reasonable TTL value.
Since this header has been already expired (ANCIENT is set), set the
rdataset TTL to 0 and don't reuse this field to print the expiration
time when dumping the cache. Instead of printing the time, we now
just print 'expired (awaiting cleanup'.
(cherry picked from commit 1bbb57f81b)
the search for the deepest known zone cut in the cache could
improperly reject a node containing stale data, even if the
NS rdataset wasn't the data that was stale.
this change also improves the efficiency of the search by
stopping it when both NS and RRSIG(NS) have been found.

dns_adb_flushname() calls dns_name_hash() to determine the ADB bucket
number to search for the given name. Meanwhile, all other functions in
lib/dns/adb.c call dns_name_fullhash() for determining the bucket number
instead. This discrepancy causes dns_adb_flushname() to have virtually
no chances of actually removing the given name from the ADB if the
name is longer than 16 bytes (since dns_name_hash() only hashes the
first 16 bytes of the name provided to it) - more specifically, the
probability of success for names longer than 16 bytes is inversely
proportional to the number of ADB buckets in use, i.e. 1:1021 at best.
Fix by using dns_name_fullhash() instead of dns_name_hash() in
dns_adb_flushname(), so that the logic for determining the bucket number
that a given name belongs to is consistent throughout lib/dns/adb.c.
When answering queries, don't add data to the additional section if
the answer has more than 13 names in the RDATA. This limits the
number of lookups into the database(s) during a single client query,
reducing query processing load.
Also, don't append any additional data to type=ANY queries. The
answer to ANY is already big enough.
(cherry picked from commit a1982cf1bb)
Instead of running the whole resolver/ns4 server with -T noaa flag,
use it only for the part where it is actually needed. The -T noaa
could interfere with other parts of the test because the answers don't
have the authoritative-answer bit set, and we could have false
positives (or false negatives) in the test because the authoritative
server doesn't follow the DNS protocol for all the tests in the resolver
system test.
(cherry picked from commit e51d4d3b88)
The terminating conditions for the startup notify test would
occasionally get ~20 records or get +10 seconds of records due to
a bad terminating condition. Additionally 20 samples lead to test
failures. Fix the terminating condition to use the correct conditional
(-eq -> -ge) and increase the minimum number of log entries to
average over to 22.
(cherry picked from commit 46388d07a2)
After the rndc reload command finished, we might have queried the
database zone sooner than it was reloaded because rndc reloads zones
asynchronously if no specific zone was provided. We should wait for "all
zones loaded" in the ns1 log to be sure.

This adds a new test directory specifically for CAMP attacks. This first
test in this test directory follows multiple CNAME chains, restarting
the max-recursion-queries counter, but should bail when the global
maximum quota max-query-count is reached.
(cherry picked from commit 73eafaba14)
Add another option to configure how many outgoing queries per
client request is allowed. The existing 'max-recursion-queries' is
per restart, this one is a global limit.

The ns2/managed1.conf file is created by the setup.sh script. Then, in
the tests.sh script it is moved to ns2/managed.conf. The latter file
name is in mkeys extra_artifacts, but the former one is not. This is a
problem when pytest is started with the --setup-only option as it only
runs the setup.sh script (e.g., in the cross-version-config-tests CI
job) and thus failing the "Unexpected files found" assertion.
(cherry picked from commit e7d973bd00)
The nslookup system test checks the count of resolved addresses in
the CNAME tests using a 'grep' match on the hostname, and ignoring
lines containing the 'canonical name' string. In order to protect
the check from intermittent failures like the 'address in use' warning
message, which then automatically resolves after a retry, edit the
'grep' matching string to also ignore the comments (as the mentioned
warning message is a comment which contains the hostname).

Ensure that the jinja2 templates have all the environment variables
which are available to the tests present.
This omission during the original 9.18 backport caused an issue where
port numbers (determined by the pytest framework) wouldn't be available
in jinja2 templates.
On some slow systems, the test might intermittently fail due to inherent
timing issues. In our CI, this most often happens in the
system:gcc:8fips:amd64 jobs.
(cherry picked from commit a299650a6f)
When a test is re-run by the flaky plugin, the TestReport outcomes
collected in the pytest_runtest_makereport() hook should be overriden.
Each of the setup/call/teardown phases is reported again and since we
care about the overall outcome, their respective results should be
overriden so that only the outcome from the final test (re)run gets
reported.
Prior to this change, it lead to a situation where an extra_artifact
generated during the test might be ignored. This was caused because the
check was skipped, since the test was incorrectly considered as "failed"
in the case where the test would fail on the first run, but pass on a
subsequent flaky rerun.
(cherry picked from commit b66fb31dcb)
The artifact lists in clean.sh and extra_artifacts might be slightly
different. The list was updated for each test to reflect the current
state.
