Extend the timeouts system test to ensure that the maximum outgoing
transfer time (max-transfer-time-out) and maximum outgoing transfer idle
time (max-transfer-idle-out) works as expected. This is done by
lowering the limits to 5/1 minutes and testing that the connection has
been dropped while sleeping between the individual XFR messages.
(cherry picked from commit 8fed1b6461)
Extend the timeouts system test that bursts the queries for large TXT
record and never read any responses back filling up the server TCP write
buffer. The test should work with the default wmem_max value on
Linux (208k).

The isc_thread_setaffinity call was removed in !5265 and we are not
going to restore it because it was proven that the performance is better
without it. Additionally, remove the already disabled cpu system test.
The isc_thread_setconcurrency function is unused and also calling
pthread_setconcurrency() on Linux has no meaning, formerly it was
added because of Solaris in 2001 and it was removed when taskmgr was
refactored to run on top of netmgr in !4918.

the dlzexternal test driver now includes ECS, if present in the
query, in the TXT record returned for QNAME "source-addr".
(cherry picked from commit 79ddedabf8)
Apparently we forgot about DLZ when updating DNS_CLIENTINFO_VERSION
constant for ECS, which is at value "3" since ECS was introduced.
The code in example drivers and tests now hardcodes version numbers
2 (without ECS) and 3 (with ECS) depending on what a given code path
requires.

Commit c787a539d2 fixed a certain class of
intermittent system test failures caused by named instances unable to
restart. The root cause was bin/tests/system/stop.pl returning without
waiting for a named instance to remove its lock file.
Later on, it turned out that the above change causes other issues on
Windows due to the way named handles signals on that platform. Commit
761ba4514f intended to address those
issues by making the server_lock_file() subroutine in
bin/tests/system/stop.pl return an empty value on Windows, in order to
prevent the script for waiting for lock file cleanup on that platform.
Note, however, that Windows detection in that subroutine is limited to
checking whether the CYGWIN environment variable is set.
While that environment variable was not set on Unix-like systems before
commit 761ba4514f, another commit
(a33237f070, merged a few weeks later)
changed that by setting the CYGWIN environment variable to an empty
value on Unix-like systems. This made the defined($ENV{'CYGWIN'}) check
in server_lock_file() return true, inadvertently preventing
bin/tests/system/stop.pl from waiting for lock file removal before
exiting on Unix-like systems and therefore reintroducing the original
issue.
Fix by making server_lock_file() only return an empty value when the
CYGWIN environment variable is set to a non-empty value (which is what
bin/tests/system/conf.sh.win32 does). Adjust a similar check in the
pid_file_exists() subroutine in the same way for consistency.

The echo_*() and cat_*() functions in bin/tests/system/conf.sh.common
call the "read" builtin command without specifying the field separator
to use. This results in leading whitespace getting stripped from each
line of the texts passed to those functions, which mangles e.g. pytest
output, hindering test failure troubleshooting.
Address by setting IFS to an empty value for the "read" calls used in
the aforementioned helper functions.
(cherry picked from commit fb87022115)
The bin/tests/system/start.pl script truncates the named.run file for a
given named instance unless it is invoked with the --restart
command-line option. Ever since Python-based tests were introduced,
bin/tests/system/run.sh may start named instances used by a given system
test multiple times within a single run, causing the
bin/tests/system/start.pl script to truncate some of the log files
written during the test. This makes troubleshooting certain test
failures hard or even impossible.
Fix by calling bin/tests/system/start.pl with the --restart command-line
option for every start_servers() invocation except the first one.
(cherry picked from commit 65abbca79b)
When failure is expected, the `rndc` command in the catz system test
is being called directly instead of using a function, i.e.:
$RNDC -c ../common/rndc.conf -s 10.53.0.2 -p 9953 reconfig \
> /dev/null 2>&1 && ret=1
... instead of:
rndccmd 10.53.0.2 reconfig && ret=1
This is done to suppress messages like "lt-rndc: 'reconfig' failed:
failure" appearing in the message log of the test, because failure
is actually expected, and the appearance of that message can be
confusing.
The port value used in this case is not correct, making the
`rndc reload` command to fail. This error was not detected earlier
only because the failure of the command is actually expected, but
the failure happens for a "wrong" reason, and the test still passes.
Fix the error by using the existing variable instead of the fixed
number.
(cherry picked from commit 5f9d4b5db4)
Test the view reverting code by introducing a faulty dlz configuration
in named.conf and using `rndc reconfig` to check if named handles the
situation correctly.
We use "dlz" because the dlz processing code is located in an ideal
place in the view configuration function for the test to cover the
view reverting code.
This test is specifically added to the catz system test to additionally
cover the catz reconfiguration during the mentioned failed
reconfiguration attempt.

This commit converts the license handling to adhere to the REUSE
specification. It specifically:
1. Adds used licnses to LICENSES/ directory
2. Add "isc" template for adding the copyright boilerplate
3. Changes all source files to include copyright and SPDX license
header, this includes all the C sources, documentation, zone files,
configuration files. There are notes in the doc/dev/copyrights file
on how to add correct headers to the new files.
4. Handle the rest that can't be modified via .reuse/dep5 file. The
binary (or otherwise unmodifiable) files could have license places
next to them in <foo>.license file, but this would lead to cluttered
repository and most of the files handled in the .reuse/dep5 file are
system test files.
(cherry picked from commit 58bd26b6cf)
All signed zone files present in bin/tests/system/inline/ns8 should
contain the unsigned serial number in the raw-format header. Add a
check to ensure that is the case. Extend the dnssec-signzone command
line in ns8/sign.sh with the -L option to allow the zones initially
signed there to pass the newly added check. Add another zone to the
configuration for the ns8 named instance to ensure the check also passes
when multiple zones are inline-signed by a single named instance.

Change RSASHA1 to $DEFAULT_ALGORITHM to be FIPS compliant.
There is one RSASHA1 occurence left, to test that dynamically adding an

(cherry picked from commit 6e9fed2d24)
Update the autosign system test with new expected behavior.
The 'nozsk.example' zone should have its expired zone signatures
deleted and replaced with signatures generated with the KSK.
The 'inaczsk.example' zone should have its expired zone signatures
deleted and replaced with signatures generated with the KSK.
In both scenarios, signatures are deleted, not retained, so the
"retaining signatures" warning should not be logged.
Furthermore, thsi commit fixex a test bug where the 'awk' command
always returned 0.
Finally, this commit adds a test case for an offline KSK, for the zone
'noksk.example'. In this case the expired signatures should be retained
(despite the zone being bogus, but resigning the DNSKEY RRset with the
ZSK won't help here).

(cherry picked from commit 3ecaccb961)
The catz system test included a test case that was looking for a single
answer record after an update, when it should have been looking for two.
The test usually passed because of timing - the first dig usually got a
response before the update was completed - but occasionally the update
processed fast enough for the test to fail. On investigation, it turned
out to be the test that was wrong.
(cherry picked from commit 9b6060c6c4)
The digdelv system test has a test case in which stderr was
included in the dig output. When trace logging was in use,
this confused the grep and caused a spurious test failure.
(cherry picked from commit 2143120636)
Update the 'catz' system test by adding tests that update an
catalog zone (catalog1.example) while preserving existing entries
(increase SOA serial) then check that catalog zone has transferred
and that the existing entries have not accidentally been removed
as a consequence (can return updated zone content).
(cherry picked from commit bf9c569852)
The qmin system test was printing spurious output. On investigation,
the test case turned out to be both broken and ineffective: its
expectations were wrong, and it was printing the output because its
wrong expectations were not met, and those failed expectations were
not causing a test failure. All of this has been corrected.

- 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

(cherry picked from commit 8a4c44ca24)
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.

This commit modifies the MTU of the loopback interface on
