Since the log level has been raised, busy servers can "explode" from
the amount of log messages. Use the usual practice of logging "every
once in a while".
(cherry picked from commit 1962857ac4)
The "RPZ not ready yet" message is logged at debug 3 level. Use the
info level instead for better visibility.
After raising the log level, the rpz_log_fail_helper() function starts
appending " failed: " the the message. Change the log message so it
makes more sense.

is needed later. Only insert the NUL immediately before
displaying just the prefix string.

Mark the ``tkey-domain`` statement as obsolete, since it has not had any
effect on server behavior since support for TKEY Mode 2 (Diffie-Hellman)
was removed (in BIND 9.20.0).

Backport of MR !10798
Merge branch 'backport-4204-obsolete-tkey-domain-9.20' into 'bind-9.20'
See merge request isc-projects/bind9!10926
The "tkey-domain" statement has effectively been a no-op since commit
bd4576b3ce, which removed the only bit of
code using it: the logic implementing TKEY Mode 2 (Diffie-Hellman).
A subsequent cleanup commit, 885c132f4a,
also missed the opportunity to remove the "tkey-domain" statement
altogether.
Mark the "tkey-domain" statement as obsolete and remove all code and
documentation related to it.
(cherry picked from commit 805f1c0f65)
The :any:`tkey-gssapi-keytab` statement allows GSS-TSIG to be set up in
a simpler and more reliable way than using the
:any:`tkey-gssapi-credential` statement and setting environment
variables (e.g. ``KRB5_KTNAME``). Therefore, the
:any:`tkey-gssapi-credential` statement has been deprecated;
:any:`tkey-gssapi-keytab` should be used instead.
For configurations currently using a combination of both
:any:`tkey-gssapi-keytab` *and* :any:`tkey-gssapi-credential`, the
latter should be dropped and the keytab pointed to by
:any:`tkey-gssapi-keytab` should now only contain the credential
previously specified by :any:`tkey-gssapi-credential`.

simpler and more reliable way than using the "tkey-gssapi-credential"
statement and setting environment variables (e.g. KRB5_KTNAME).
Mark the "tkey-gssapi-credential" statement as deprecated to eventually
only have one method for setting up GSS-TSIG in named. Do not mention
"tkey-gssapi-credential" in the section of the ARM on dynamic updates.

Clang 20 was spuriously warning about the possibility of passing a NULL file pointer
to `fprintf()`, which uses the 'nonnull' attribute. To silence the warning, the functions
calling `fprintf()` have been marked with the same attribute to assure that NULL can't be
passed to them in the first place.

Testing all combinations seems unnecessary but is cheap.
I was too lazy to run this against all tools we have. nsupdate was
chosen because it is one of few tools which actually use stdin and the
original issue was reproducible even without any network communication,
which was not the case for simple dig invocation.
Sorry for new shell test but doing this in Python seemed very
complicated and fragile.

A catalog zone with an unset ``default-primaries`` clause could cause
an unexpected termination of the :iscman:`named` process after two
reloading or reconfiguration commands. This has been fixed.
Closes#5494

And unset 'default-primaries' is causing an assertion failure after
two reload/reconfig commands. Add such a catalog zone to check the fix.
(cherry picked from commit 40d040b7d5)
When dns_catz_zone_add() returns ISC_R_EXISTS and there is no
'default-primaries' or 'default-masters', the ISC_R_EXISTS result
code doesn't get reset to ISC_R_SUCCESS, and the function returns
ISC_R_EXISTS instead of ISC_R_SUCCESS. Which means that the zone
is successfully added, but the caller assumes that the function has
failed.
Reset 'result' to ISC_R_SUCCESS when dns_catz_zone_add() returns
ISC_R_EXISTS (it's not an error condition).
Refactor the code go call dns_catz_zone_add() when all other error
conditions are already checked.

By default, when :iscman:`named` is started it may start answering to
queries before the response policy zones are completely loaded
and processed. This new feature gives an option to the users to
tell :iscman:`named` that incoming requests should result in SERVFAIL answer
until all the response policy zones are processed and ready. Note that if
one or more response policy zones fail to load, :iscman:`named` starts
responding to queries according to those zones that did load.
Note, that enabling this option has no effect when a DNS Response Policy
Service (DNSRPS) interface is used.

The 'scan-build' job in the CI reports a false positive:

2704 * first time.

2708 pview->rpzs->first_time = false;
>> Access to field 'first_time' results in a dereference of a null pointer (loaded from field 'rpzs')
Add INSISTs to silence the report.
When a DNS Response Policy Service (DNSRPS) interface is used, the
'servfail-until-ready yes' option is ignored, because RPZ zones are
not processed by BIND.
The complier claims that 'qresult_type' may be used uninitialized,
though all the cases inside the switch either set the variable
or return from the function, and the warning is generated on a line
after the switch-case block.
Slightly modify the code to set a default value for the variable when
declaring it.

Test whether 'servfail-until-ready yes' works by enabling slow
RPZ loading with a USDT probe activation, and checking that named
returns SERVFAIL during the initial RPZ zones processing stage.
The test requires SystemTap (stap, dtrace) to activate the USDT
probe.

During the initial configuration of named after startup, 'first_time'
is true. This is needed for implementing the new 'servfail-until-ready'
configuration option, which should take into effect only during the
initial configuration.
(cherry picked from commit 88ed81e12d)
Add a new option ``manual-mode`` to :any:`dnssec-policy`. The intended use is that if it is enabled, it will not automatically move to the
next state transition, but instead the transition is logged. Only after manual confirmation with ``rndc dnssec -step`` the transition is made.
