The old code could incorrectly match "INSOA" in the RRSIG rdata
when looking for the SOA record.

The BUFSIZ value varies between platforms, it could be 8K on Linux and
512 bytes on mingw. Make sure the buffers are always big enough for the
output data to prevent truncation of the output by appropriately
enlarging or sizing the buffers.

Some zones where not being logged when just DNSSEC keys where being
generated in system test setup phase. Add logging for these zones.

There should be 2 keys with the same key id after the numerically
lower one is revoked (serial space arithmetic). The DS points
at the non-revoked key so validation should still succeed.

When dnssec-policy is used, and the zone is not dynamic, BIND will
assume that the zone is inline-signed. Add test cases to verify this.

Fix a comment, ensuring the right parameters are used (zone is
parameter $3, not $2) and add view and policy parameters to the comment.
Fix the view tests and test the correct view (example3 instead of
example2).
Fix placement of "n=$((n+1)" for two test cases.

* make it harder to get the interface numbers wrong by using 'max'
to specify the upper bound of the sequence of interfaces and use 'max'
when calculating the interface number
* extract the platform specific instruction into 'up' and 'down'
and call them from the inner loop so that the interface number is
calculated in one place.
* calculate the A and AAAA address in a single place rather than
in each command
* use /sbin/ipadm on Solaris 2.11 and greater

The original sscanf processing allowed for a number of syntax errors
to be accepted. This included missing the closing brace in
${modifiers}
Look for both comma and right brace as intermediate seperators as
well as consuming the final right brace in the sscanf processing
for ${modifiers}. Check when we got right brace to determine if
the sscanf consumed more input than expected and if so behave as
if it had stopped at the first right brace.

On slow systems we have seen this take 9 seconds. Increased the
allowance from 3 seconds to 10 seconds to reduce the probabilty of
a false negative from the system test.

The previous test code could emit "D:cds:stderr did not match ''" rather

If skip/xfail is used in pytest, it can have a reason string associated
with it. When evaluating these tests, it can be useful to be able to
differentiate the reason why the test was skipped/xfailed/xpassed,
because there might be multiple possible reasons for that.
The extra options passed to pytest ensure that the string with the
reason appears in the test summary and thus we're able to find the
string with the reason in the log output.

In the cases where we test SOA serial updates and TTL updates, we check
if for "all zones loaded" to ensure the new zone content is loaded. But
this is the unsigned zone, the signed zone still needs to be produced.
There is thus a timing issue where the dig request comes in before
the signing process has finished.
Add a retry quiet to mitigate against it.

The perl modifation code for keyless.example was not deterministic

7249bad7 introduced the -c option to stat(1) command, but BSD systems
do not know about it. Replace the stat(1) command with a PERL script
that achieves the same.
Why PERL? For consistency purposes, there are more places in the
system test where we use the same method.

Check that the recursing client count is above a reasonable
minimum, as well as below a maximum, so that we can detect
bugs that cause recursion to fail too early or too often.
(cherry picked from commit 8834c44683)
The fetchlimit test depends on a resolver continuing to try UDP
and timing out while the client waits for resolution to succeed.
but since commit bb990030 (flag day 2020), a fetch will always
switch to TCP after two timeouts, unless EDNS was disabled for
the query.
This commit adds "edns no;" to server statements in the fetchlimit
resolver, to restore the behavior expected by the test.

RPZ NSIP and NSDNAME checks were failing with "unrecognized NS
rpz_rrset_find() failed: glue" when static or static-stub zones
where used to resolve the query name.
Add tests using stub and static-stub zones that are expected to
be filtered and not-filtered against NSIP and NSDNAME rules.
stub and static-stub queries are expected to be filtered
stub-nomatch and static-stub-nomatch queries are expected to be passed

The dig commands appear to be failing unexpectedly on some platforms
when rate limiting kicks in and the response is dropped. Correct
behaviour should be for dig to retry the query. Set +qr and capture
stdout and stderr of each of the dig commands involved.

In '_check_apex_dnskey' we check for each key (KEY1 to KEY4) if they
are present in the DNSKEY RRset if they should be.
However, we only grep the dig output for the first seven fields (owner,
ttl, class, type, flags, protocol, algorithm). This can be the same
for different keys.
For example, KEY1 may be KSK predecessor and KEY2 a KSK successor,
both DNSKEY records for these keys are the same up to the public key
field. This can cause test failures if KEY1 needs to be present, but
KEY2 not, because when grepping for KEY2 we will falsely detect the
key to be present (because the grep matches KEY1).
Fix the function by grepping looking for the first seven fields in the
corresponding key file and retrieve the public key part. Grep for this
in the dig output.
(cherry picked from commit 3e1d09ac66)
Prime the cache with a negative cache DS entry then make a query for
name beneath that entry. This will cause the DS entry to be retieved
as part of the validation process. Each RRset in the ncache entry
will be validated and the trust level for each will be updated.
(cherry picked from commit d2d9910da2)
Add a test case for a dynamically added CDS DELETE record and make
sure it is not removed when signing the zone. This happens because
BIND maintains CDS and CDNSKEY publishing and it will only allow
CDS DELETE records if the zone is transitioning to insecure. This is
a state that can be identified when using KASP through 'dnssec-policy',
but not when using 'auto-dnssec'.

Commit 59d1eb3ff8 added a Python-based
name server (bin/tests/system/forward/ans11/ans.py) to the "forward"
system test, but did not update the bin/tests/system/forward/prereq.sh
script to ensure Python is present in the test environment before the
"forward" system test is run. Update bin/tests/system/forward/prereq.sh
to enforce that requirement.
- Check that an NS in an authority section returned from a forwarder
which is above the name in a configured "forward first" or "forward
only" zone (i.e., net/NS in a response from a forwarder configured for
local.net) is not cached.
- Test that a DNAME for a parent domain will not be cached when sent
in a response from a forwarder configured to answer for a child.
- Check that glue is rejected if its name falls below that of zone
configured locally.
- Check that an extra out-of-bailiwick data in the answer section is
not cached (this was already working correctly, but was not explicitly
tested before).

Add a test case to check for lingering TCP sockets stuck in the
CLOSE_WAIT state. This can happen if a client sends some garbage after
its first query.
The system test runs the reproducer script and then sends another TCP
query to the resolver. The resolver is configured to allow one TCP
client only. If BIND has its TCP socket stuck in CLOSE_WAIT, it does
not have the resources available to answer the second query.
Note: A better test would be to check if the named daemon does not
have a TCP socket stuck in CLOSE_WAIT for example with netstat. When
running this test locally you can examine named with netstat manually.
But since netstat is platform specific it is not a good candidate to do
this as a system test.
If you, if you could return, don't let it burn.
Do you have to let it linger?

Enable use of shortcuts like pytest.importorskip and other tricks

(cherry picked from commit b8829c801f)
In addition to b8829c801f,
"R:$systest:SKIPPED" is not being printed when pytests are skipped
because that leads to two `R:` lines - SKIPPED and PASS/FAIL which is
determined later based on other conditions (core files identified,
assertion failures, shell test result, ...) - which is wrong and
testsummary.sh rightfully stumbles on it:
I:Found 106 test results, but 105 tests were run
The launchd script only counted up to 8 whereas ifconfig.sh went all
the way up to 10, and even a bit further than that.

the line "$GENERATE 19-28/2147483645 $ CNAME x" should generate
a single CNAME with the owner "19.example.com", but prior to the
overflow bug it generated several CNAMEs, half of them with large
negative values.
we now test for the bugfix by using "named-checkzone -D" and
grepping for a single CNAME in the output.

Ensure the update zone name is mentioned in the NOTAUTH error message
in the server log, so that it is easier to track down problematic
update clients. There are two cases: either the update zone is
unrelated to any of the server's zones (previously no zone was
mentioned); or the update zone is a subdomain of one or more of the
server's zones (previously the name of the irrelevant parent zone was
misleadingly logged).

Historically, the inline keyword was a strong suggestion to the compiler
that it should inline the function marked inline. As compilers became
better at optimising, this functionality has receded, and using inline
as a suggestion to inline a function is obsolete. The compiler will
happily ignore it and inline something else entirely if it finds that's
a better optimisation.
Therefore, remove all the occurences of the inline keyword with static
functions inside single compilation unit and leave the decision whether
to inline a function or not entirely on the compiler
NOTE: We keep the usage the inline keyword when the purpose is to change
the linkage behaviour.

Previously, the unreachable code paths would have to be tagged with:
INSIST(0);
ISC_UNREACHABLE();
There was also older parts of the code that used comment annotation:
/* NOTREACHED */
Unify the handling of unreachable code paths to just use:
UNREACHABLE();
The UNREACHABLE() macro now asserts when reached and also uses
__builtin_unreachable(); when such builtin is available in the compiler.

Gcc 7+ and Clang 10+ have implemented __attribute__((fallthrough)) which
is explicit version of the /* FALLTHROUGH */ comment we are currently
using.
Add and apply FALLTHROUGH macro that uses the attribute if available,
but does nothing on older compilers.
In one case (lib/dns/zone.c), using the macro revealed that we were
using the /* FALLTHROUGH */ comment in wrong place, remove that comment.

The clang-format-15 has new option InsertBraces that could add missing
branches around single line statements. Use that to our advantage
without switching to not-yet-released LLVM version to add missing braces
in couple of places.
The dns.query Python module has the send_tcp() method defined in both
dnspython 1.x and 2.x, so checking for the existence of that method to
determine the dnspython version available in the test environment does
not make any sense. Fix by checking the dns.version.MAJOR integer
instead.
The ability to conveniently mark tests which should only be run when the
CI_ENABLE_ALL_TESTS environment variable is set seems to be useful on a
general level and therefore it should not be limited to the "timeouts"
system test, where it is currently used.
pytest documentation [1] suggests to reuse commonly used test markers by
putting them all in a single Python module which then has to be imported
by test files that want to use the markers defined therein. Follow that
advice by creating a new bin/tests/system/pytest_custom_markers.py
Python module containing the relevant marker definitions.
Note that "import pytest_custom_markers" works from a test-specific
subdirectory because pytest modifies sys.path so that it contains the
paths to all parent directories containing a conftest.py file (and
bin/tests/system/ is one). PyLint does not like that, though, so add a
relevant PyLint suppression.
The above changes make bin/tests/system/timeouts/conftest.py redundant,
so remove it.
