previously, when an iterative query returned FORMERR, resolution
would be stopped under the assumption that other servers for
the same domain would likely have the same capabilities. this
assumption is not correct; some domains have been reported for
which some but not all servers will return FORMERR to a given
query; retrying allows recursion to succeed.

We are grafting on an unsigned zone "example.internal" where the higher
zone (".") is signed and would otherwise cause named to synthesise a
NXDOMAIN for example.internal. We prime the cache by performing a
lookup for "internal" and then lookup "example.internal".

We do this by adding callbacks for when a node is added or deleted
from the keytable. dns_keytable_add and dns_keytable_delete where
extended to take a callback. dns_keytable_deletekey does not remove
the node so it was not extended.

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.

$GENERATE uses 'int' for its computations and some constructions
can overflow values that can be represented by an 'int' resulting
in undefined behaviour. Detect these conditions and return a
range error.

On slow systems we have seen this take 9 seconds. Increased the

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

The name yes_or_no was used only in two places and rest of the ARM
(except for the grammar glossary...) uses term boolean. Let's stick to
it.
(cherry picked from commit 0138e5c1d5)
The next commit is going to add parser for ISC configuration format.
To simplify the parser the grammar files in doc/misc are no longer
line-wrapped as handling it would make the grammar parser unnecessairly
complicated.
This affects visible output in the ARM, but in the end we are going to
replace the auto-generated .rst files with grammar pretty printed, so
formatting of these files does not matter in practical terms.

This way only quota size is passed to the interface/listener

The function actually did not enforce that the duration string starts

Remove the duplication from the defaultconf and inherit the values
not set in the "insecure" policy from the "default" policy. Therefore,
we must insist that the first read built-in policy is the default one.
(cherry picked from commit c2a7950417)
Most of the settings (durations) are already inheriting from the default
because they use the constants from lib/dns/kasp.h. We need them as
constants so we can use them in named-checkconf to verify the policy
parameters.
The NSEC(3) parameters and keys should come from the actual default
policy. Change the call to cfg_kasp_fromconfig() to include the default
kasp. We also no longer need to corner case where config is NULL we load
the built-in policy: the built-in policies are now loaded when config is
set to named_g_config.
Finally, add a debug log (it is useful to see which policies are being
loaded).
(cherry picked from commit 20acb8d3a3)
Update the defaultconf with the built-in policies. These will now be
printed with "named -C".
Change the defines in kasp.h to be strings, so they can be concatenated
in the defaultconf. This means when creating a kasp structure, we no
longer initialize the defaults (this is fine because only kaspconf.c
uses dns_kasp_create() and it inherits from the default policy).
In kaspconf.c, the default values now need to be parsed from string.
Introduce some variables so we don't need to do get_duration multiple
times on the same configuration option.
Finally, clang-format-14 decided to do some random formatting changes.

Have system tests use required Python (dnspython) and PERL modules
(Digest::HMAC and Net::DNS) from user directories, avoid using

Note: The pythonenv must be setup to use the same version of python as
the test uses, for example /usr/bin/python.

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.

This commit removes dead code from cleanup handling part of the
get_create_tls_context().
In particular, currently:
* there is no way 'found_ctx' might equal 'ctx';
* there is no way 'session_cache' might equal a non-NULL value while
cleaning up after a TLS initialisation error.

This commit ensures that isc_nm_cancelread() is not called from within
dig code for HTTP sockets, as these lack its implementation.
It does not have much sense to have it due to transactional nature of
HTTP.
Every HTTP request-response pair is represented by a virtual socket,
where read callback is called only when full DNS message is received
or when an error code is being passed there. That is, there is nothing
to cancel at the time of the call.

In special NS search mode, after the initial lookup, dig starts the
followup lookup with discovered NS servers in the queries list. If one
of those queries then fail, dig, as usual, tries to start the next query
in the list, which results in a crash, because the NS search mode is
special in a way that the queries are running in parallel, so the next
query is usually already started.
Apply some special logic in `recv_done()` function to deal with the
described situation when handling the query result for the NS search
mode. Particularly, print a warning message for the failed query,
and do not try to start the next query in the list. Also, set a non-zero
exit code if all the queries in the followup lookup fail.

The statistics system test fails on Oracle Linux 7 when libxml2, Curl,
and xsltproc are present:
I:statistics:checking bind9.xsl vs xml (17)
diff: curl.out.17.xsl: No such file or directory
tests.sh: line 183: curl.out.17.xml: No such file or directory
cp: cannot stat 'curl.out.17.xml': No such file or directory
grep: xsltproc.out.17: No such file or directory
This is because the Oracle Linux 7 Curl does not know about the
--http1.1 option and silently fails with:
+ /usr/bin/curl --http1.1 http://10.53.0.3:7252
curl: option --http1.1: is unknown
curl: try 'curl --help' or 'curl --manual' for more information
The following test "checking bind9.xml socket statistics" then needs to
check for existence of stats.xml.out file which is artifact of the
previous test.

Add a new test to check that a catalog zone member zone does not

There is no reason for these two messages to be `ISC_LOG_INFO` while all
the other similar messages in `catz_addmodzone_taskaction()` and
`catz_delzone_taskaction()` functions are logged as `ISC_LOG_WARNING`.

When processing a catalog zone member zone make sure that there is no
configured pre-existing forward zone with that name.
Refactor the `dns_fwdtable_find()` function to not alter the
`DNS_R_PARTIALMATCH` result (coming from `dns_rbt_findname()`) into
`DNS_R_SUCCESS`, so that now the caller can differentiate partial
and exact matches. Patch the calling sites to expect and process
the new return value.
(cherry picked from commit 2aff264fb1)
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 key lifetime should not be shorter than the time it costs to
introduce the successor key, otherwise keys will be created faster than
they are removed, resulting in a large key set.
The time it takes to replace a key is determined by the publication
interval (Ipub) of the successor key and the retire interval of the
predecessor key (Iret).
For the ZSK, Ipub is the sum of the DNSKEY TTL and zone propagation
delay (and publish safety). Iret is the sum of Dsgn, the maximum zone
TTL and zone propagation delay (and retire safety). The sign delay is
the signature validity period minus the refresh interval: The time to
ensure that all existing RRsets have been re-signed with the new key.
The ZSK lifetime should be larger than both values.
For the KSK, Ipub is the sum of the DNSKEY TTL and zone propagation
delay (and publish safety). Iret is the sum of the DS TTL and parent
zone propagation delay (and retire safety). The KSK lifetime should be
larger than both values.
