The dns__catz_update_cb() function was earlier updated (see
d2ecff3c4a) to use a separate
'dns_db_t' object ('catz->updb' instead of 'catz->db') to
avoid a race between the 'dns__catz_update_cb()' and
'dns_catz_dbupdate_callback()' functions, but the 'REQUIRE'
check there still checks the validity of the 'catz->db' object.
Fix the omission.

These options and zone type were created to address the
SiteFinder controversy, in which certain TLD's redirected queries
rather than returning NXDOMAIN. since TLD's are now DNSSEC-signed,
this is no longer likely to be a problem.
The deprecation message for 'type delegation-only' is issued from
the configuration checker rather than the parser. therefore,
isccfg_check_namedconf() has been modified to take a 'nodeprecate'
parameter to suppress the warning when named-checkconf is used with
the command-line option to ignore warnings on deprecated options (-i).

When resquery_response() was called with ISC_R_SHUTTINDOWN, the region
argument would be NULL, but rctx_respinit() would try to pass
region->base and region->len to the isc_buffer_init() leading to
a NULL pointer dereference. Properly handle non-ISC_R_SUCCESS by
ignoring the provided region.

Previously, an AXFR request would be issued every second while waiting
for the zone to be signed. This might've been the cause of issues in CI
where many tests are running in parallel and any extra load may increase
test instability.
Instead, check for the last NSEC record to have a signature before
commencing the AXFR request to check the zone has been fully signed.
Also increase the time for the zone signing to a total of 60+10 seconds
up from the previous 30.

There's no point in continuing the dupsigs test if a failure is
detected. End the test early to avoid wasting time and resources.
(cherry picked from commit ad647dca13)
Ensure messages from dupsigs system test end up in its log rather than
stdout. Previously, the output was hard to debug when running the tests
in parallel and messages wouldn't end up in the dupsigs.log.

This should delay the catalog zone from being destroyed during
shutdown, if the update process is still running.
Doing this should not introduce significant shutdown delays, as
the update function constantly checks the 'shuttingdown' flag
and cancels the process if it is set.

The instance-wide GitLab CI artifact retention time was changed to 1 day
up from the previous value of 12 hours. Remove our explicit overrides
for 1 day artifact retention time, as it is the default now.
Previously, most of our jobs had overrides for 1 day retention, while
some of our jobs used the default 12 hours. This discrepancy could be
quite impractical at times.

This commit ensures that 'sock->tls.pending_req' is not getting
nullified during TLS connection timeout callback as it prevents the
connection callback being called when connecting was not successful.
We expect 'isc__nm_failed_connect_cb() to be called from
'isc__nm_tlsdns_shutdown()' when establishing connections was
successful, but with 'sock->tls.pending_req' nullified that will not
happen.
The code removed most likely was required in older iterations of the
NM, but to me it seems that now it does only harm. One of the well
know pronounced effects is leading to irrecoverable zone transfer
hangs via TLS.
If the zone already has existing NSEC/NSEC3 chains then zone_sign
needs to continue to use them. If there are no chains then use
kasp setting otherwise generate an NSEC chain.

dns_dnssec_updatekeys's 'report' could be called with invalid arguments
which the compiler should be be able to detect.
(cherry picked from commit 7a0a2fc3e4)
The dnstap system test fails intermittently, and it appears to be
a timing issue - adding a short delay after running 'fstrm_capture',
and before running 'dnstap -reopen' improves the situation from
50% failures (5 out of 10 times) to 0% failures (0 out of 20 times),
tested locally.
The reason is that 'fstrm_capture' is executed in the background,
and due to OS scheduling and other factors, the listener socket
may not be ready when the following command runs and tells 'named'
to (re)open it.

BUILD_PARALLEL_JOBS environmental variable is set to 6, which does not
align well with 4 and 8 CPU core systems dedicated to CI "stress" tests.
When multiple parallel jobs run on the host, they compete for resources
with an undesirable result: 6 compiler processes of one job may starve
named, resulting in lower-than-expected throughput and minutes-long
query response latency spikes.
Better drop the build parallelism of BIND-under-test. About 1-2 minutes
are added to the 60-65 minutes long job duration.

Dumping of the freshly transferred zone file can take some time.
Retry 5 times before failing.
The log excerpt below shows such a case, when dumping lasted more than
two seconds.

There can be comments in dig output for a zone transfer only in case
of an error, so we should print those errors not when wait_for_tls_xfer
succeeds, but when it fails.
Also, there is no point in printing those comments when a failure was
indeed expected.
(cherry picked from commit 9672b6be57)
If wait_for_tls_xfer succeeds, while a failure was being expected,
set ret=1 to fail without further checking if the zone file exists.

By omission, BIND was not built with common CFLAGS in the stress test
jobs. Building with common CFLAGS and -Og should help GDB produce a
backtrace with more information.
(cherry picked from commit d33bdd36b4)
The serve-stale system test was intermittently failing due to a timing
issue:
I:serve-stale:check stale data.example TXT was refreshed...
I:serve-stale:failed
The RRset is refreshed, however, it first checks for an expected log
line, prior checking that the stale data.example TXT was refreshed
(using dig). This log line is there to ensure the record is actually
refreshed before we start querying again. Alternatively we could just
retry_quiet 10 <wait for dig output matches expectations>. It would
lower the chances for intermittent test failures, since there is no
longer a "check for log line, sleep one second if check fails, check
for log line, ...", prior to the check.
