- when transfer-source(-v6), query-source(-v6), notify-source(-v6)
or parental-source(-v6) are specified with a port number, issue a
warning.
- when the port specified is the same as the DNS listener port (i.e.,
53, or whatever was specified as "port" in "options"), issue a fatal
error.
- check that "port" is in range. (previously this was only checked
by named, not by named-checkconf.)
- added checkconf tests.
- incidental fix: removed dead code in check.c:bind9_check_namedconf().
(note: if the DNS port is specified on the command line with "named -p",
that is not conveyed to libbind9, so these checks will not take it into
account.)

The ns3->ns2 forwarding is now done using the IPv6 addresses, so we also
test that the query-source-v6 address is still operational after removal
of interface adjustment.
(cherry picked from commit 8a4c44ca24)
Previously, named would run with a configuration
where *-source-v6 (notify-source-v6, transfer-source-v6 and
query-source-v6) address and port could be simultaneously used for
listening. This is no longer true for BIND 9.16+ and the code that
would do interface adjustments would unexpectedly disable listening on
TCP for such interfaces.
This commit removes the code that would adjust listening interfaces
for addresses/ports configured in *-source-v6 option.

when "checking lame server clients are dropped below the hard limit",
periodically a query is sent for a name for which the server is
authoritative, to verify that legitimate queries can still be
processed while the server is dealing with a flood of lame delegation
queries. those queries used the same dig options as elsewhere in the
fetchlimit test, including "+tries=1 +timeout=1". on slow systems, a
1-second timeout may be insufficient to get an answer even if the server
is behaving well. this commit increases the timeout for the check
queries to 2 seconds in hopes that will be enough to eliminate test
failures in CI.

When BIND is running as a Windows Service the ISC library's
initializations initiated by the DLLMain loading procedure are
happening under the Windows Service Manager thread instead of
BIND's main thread.
This commit will make sure that BIND's main thread trampoline has
been initialized before running the main() function.
This commit modifies the MTU of the loopback interface on
Linux systems to 1500, so that oversized UDP packets can
trigger EMSGSIZE errors, and tests that named handles
such errors correctly.
Note that the loopback MTU size has not yet been modified
for other platforms.

test server now has tcp-idle-timeout set to 5 seconds and
tcp-keepalive-timeout set to 7, so queries that follow a 6-second sleep
should either succeed or fail depending on whether the keepalive option
was sent.

Add a statschannel test case to confirm that when keys are removed
(in this case because of a dnssec-policy change), the corresponding
dnssec-sign stats are cleared and are no longer shown in the
statistics.
(cherry picked from commit 1a3c82f765)
Add a test case that has more than four keys (the initial number of
key slots that are created for dnssec-sign statistics). We shouldn't
be expecting weird values.
This fixes some errors in the manykeys zone configuration (keys
were created for algorithm RSASHA256, but the policy expected RSASHA1,
and the zone was not allowing dynamic updates).
This also fixes an error in the calls to 'zones-json.pl': The perl
script excepts an index number where the zone can be found, rather
than the zone name.

In order to test cases with non-SEP CSK keys, the Flags Field needs to
be determined differently to deal with such exceptional scenarios.
(cherry picked from commit 36ad0331e2)
Add a test case for migrating CSK to dnssec-policy. The keymgr has no
way of telling that the key is used as a CSK, but if there is only one
key to migrate it is going to assume it must be a CSK.
(cherry picked from commit 96ee323622)
Add a test case for GL #2845 where a zone is in two views, one base
view and one "in-view" and that zone is using an $INCLUDE. Make sure
that there is a jnl file (have ixfr-from-differences enabled and do a
dynamic update). Then freeze and make updates in the included file
(this requires the test.db file also to be updated because 'rndc freeze'
causes the zone file to be overwritten). Finally reload and ensure that
the edit in the included file has been loaded.

string.endswith("label.sequence") doesn't check for the implict
period before "label.sequence" when matching longer strings.
"foo.label.sequence" should match but "foolabel.sequence shouldn't".
(cherry picked from commit f79876b2d5)
Add test cases for GL #2665: The QNAME minimization (if enabled) should
also occur on the second query, after the RRsets have expired from
cache. BIND will still have the entries in cache, but marked stale.
These stale entries should not prevent the resolver from minimizing
the QNAME. We query for the test domain a.b.stale. in all cases (QNAME
minimization off, strict mode, and relaxed mode) and expect it to
behave the same the second time we have a stale delegation structure in
cache.
(cherry picked from commit 322626ab5b)
Add a test case to the dnssec system test to check that:
- a zone with a prepublished key is only signed with the active key.
- a zone with an inactive key but valid signatures retains those
signatures and does not add signatures from successor key.
- signatures are swapped in a zone when signatures of predecessor
inactive key are within the refresh interval.
(cherry picked from commit 35efbc270f)
When signing with a ZSK, check if it has a predecessor. If so, and if
the predecessor key is sane (same algorithm, key id matches predecessor
value, is zsk), check if the RRset is signed with this key. If so, skip
signing with this successor key. Otherwise, do sign with the successor
key.
This change means we also need to apply the interval to keys that are
not actively signing. In other words, 'expired' is always
'isc_serial_gt(now + cycle, rrsig.timeexpire)'.
Fix a print style issue ("removing signature by ..." was untabbed).

The support for stat.pl's --restart option was incomplete in run.sh.
This change makes sure it's handled properly and that named.run file is
not being removed by clean.sh when the --restart option is used.
(cherry picked from commit a39697635b)
When named failed to start and produced core dump, the core file wasn't
processed by GDB because of run.sh script exiting immediately. This
remedies the limitation, simplifies the surrounding code, and makes the
script shellcheck clean.
(cherry picked from commit bc097d3358)
Extend the "chain" system test with AUTHORITY section checks for signed,
secure delegations. This complements the checks for signed, insecure
delegations added by commit 82b7e6ccef.
Extend the existing AUTHORITY section checks for signed, insecure
delegations to ensure nonexistence of DS RRsets in such responses.
Adjust comments accordingly.
Ensure dig failures cause the "chain" system test to fail.
(cherry picked from commit a14efdf54c)
Add tests to the nsupdate system test to make sure that CDS and/or
CDNSKEY that match an algorithm in the DNSKEY RRset are allowed. Also
add tests that updates are rejected if the algorithm does not match.
Remove the now redundant test cases from the dnssec system test.
Update the checkzone system test: Change the algorithm of the CDS and
CDNSKEY records so that the zone is still rejected.
(cherry picked from commit 6b79db1fdd)
As we don't set the thread affinity, the cpu test would consistently
fail. Disable it, but don't remove it as we might restore setting the
affinity in the future versions of BIND 9.
