Check that the fix in the previous commit works and that the
'ServerQuota' counter in the statistics channel is still unset
after a SERVFAIL result in a 'forward only' zone.
(cherry picked from commit 81b3c5d908)
Silence Coverity CID 468757 and 468767 (DATA RACE read not locked)
by converting dnssec-signzone to use atomics for statistics counters
rather than using a lock. This should be marginally faster than
using the lock as well when statistics are requested.
(cherry picked from commit 473cbd4e87)
This change allows fallback from an IXFR failure to AXFR when the
reason is DNS_R_TOOMANYRECORDS. This is because this error condition
could be temporary only in an intermediate version of IXFR
transactions and it's possible that the latest version of the zone
doesn't have that condition. In such a case, the secondary would never
be able to update the zone (even if it could) without this fallback.
This fallback behavior is particularly useful with the recently
introduced max-records-per-type and max-types-per-name options:
the primary may not have these limitations and may temporarily
introduce "too many" records, breaking IXFR. If the primary side
subsequently deletes these records, this fallback will help recover
the zone transfer failure automatically; without it, the secondary
side would first need to increase the limit, which requires more
operational overhead and has its own adverse effect.
This change also fixes a minor glitch that DNS_R_TOOMANYRECORDS wasn't
logged in xfrin_fail.

Administrators may wish to constrain the set of cores that BIND 9 runs
on via the 'taskset', 'cpuset' or 'numactl' programs (or equivalent on
other O/S), for example to achieve higher (or more stable) performance
by more closely associating threads with individual NIC rx queues. If
the admin has used taskset, it follows that BIND ought to
automatically use the given number of CPUs rather than the system wide
count.

Return partial match from dns_db_find/dns_db_find when requested
to short circuit the closest encloser discover process. Most of the
time this will be the actual closest encloser but may not be when
there yet to be committed / cleaned up versions of the zone with
names below the actual closest encloser.

On systems where root access is needed to configure privileged
ports, we don't want to fully relinquish root privileges until
after the control channel (which typically runs on port 953) has
been established.
named_os_changeuser() now takes a boolean argument 'permanent'.
This allows us to switch the effective userid temporarily with
named_os_changeuser(false) and restore it with named_os_restoreuser(),
before permanently dropping privileges with named_os_changeuser(true).

With max-recursion-queries set to 50 the resolver system test was
unstable in the "checking query resolution for a domain with a valid
glueless delegation chain" check as ns1 replied with SERVFAIL.
(cherry picked from commit 8e0244d300)
A new argument has been added to dnssec-keygen and dnssec-keyfromlabel
to restrict the tag value of key generated / imported to a particular
range. This is intended to be used by multi-signers.

If there is a keytag conflict between keys with different algorithms,
we need to supply what key algorithm is used so we can get the right
public key.
For clarity, print the algorithm on the found keys after 'check_keys'.

Test importing a Signed Key Response. Files should be loaded and once
loaded the correct bundle should be used. Alsoe test cases where the
bundle is not the first bundle in the SKR.
(cherry picked from commit afe093258c)
Add the code and documentation required to provide KSR import using
rndc. This is just the command, and the feature is at this point in
time still not implemented.
(cherry picked from commit edbb219fda)
Prepare the system test for tests that require a server to import
created SKR files. This means the test script needs adjustments to
take into account the directory test files are located.
In addition, the check_keys function is renamed to ksr_check_keys
because the name clashes with check_keys from kasp.sh. It also has an
extra parameter added, offset, that can be used to check ksr files that
are created in the past or future.
(cherry picked from commit 367154c1de)
Add a new configuration option to enable Offline KSK key management.
Offline KSK cannot work with CSK because it splits how keys with the
KSK and ZSK role operate. Therefore, one key cannot have both roles.
Add a configuration check to ensure this.

named now prints its initial working directory during startup and the
changed working directory when loading or reloading its configuration
file if it has a valid 'directory' option defined.

It looks like that all supported systems now have support for
_POSIX_SAVED_IDS, so it's safe to use setegid() and setegid() because
those will not change saved used/group IDs.
(cherry picked from commit ab517fc6e4)
The shim implementation of setresuid() was wrong - there was a copy and
paste error and it was calling setresgid() instead. This only affects
NetBSD because Linux, FreeBSD and OpenBSD have setresuid() and
setresgid() implementation available from the system library.

The test_traffic_json and test_traffic_xml occasionally fail when
running under TSAN. This happens in CI and is most likely a result of
some instability that doesn't seem to be easily reproduced.

In rpz system tests, we could leak file if the applying the updates has
failed. Add the missing fclose() before returning.
(cherry picked from commit 2855ec8f5f)
New version of clang (19) has introduced a stricter checks when mixing
integer (and float types) with enums. In this case, we used enum {}
as C17 doesn't have constexpr yet. Change the time conversion constants
to be static const unsigned int instead of enum values.
(cherry picked from commit b03e90e0d4)
As we now setup the logging very early, parsing the default config would
always print warnings about experimental (and possibly deprecated)
options in the default config. This would even mess with commands like
`named -V` and it is also wrong to warn users about using experimental
options in the default config, because they can't do anything about
this. Add CFG_PCTX_NODEPRECATED and CFG_PCTX_NOEXPERIMENTAL options
that we can pass to cfg parser and silence the early warnings caused by
using experimental options in the default config.

Some distributions (notably, debian bookworm) have deprecated the
`python` interpreter in favor of `python3`. Since our scripts are
python3 anyway, use the proper numbered version in shebang to make
scripts easily executable.

This condition in catalog zone processing functions is checked only
for sanity, so there is no meaning for a log message that normally
shouldn't be ever logged.

During a reconfiguration named doesn't reconfigure catalog zones
member zones. Implement the necessary code to reconfigure catz
member zones.
(cherry picked from commit fd71ed5d73ae2dc968e8782ce652fb8ef257c25e)
Catalog zone member zones should be reconfigured as all the other
zones during a reconfiguration. Test it by checking whether the newly
added allow-query setting affects a member zone.

max-query-restarts and max-recursion-queries values can now be set
on the command line in delv for testing purposes.
(cherry picked from commit 0d010ddebe)
implement, document, and test the 'max-query-restarts' option
which specifies the query restart limit - the number of times
we can follow CNAMEs before terminating resolution.
(cherry picked from commit 104f3b82fb)
MAX_RESTARTS is no longer hard-coded; ns_server_setmaxrestarts()
and dns_client_setmaxrestarts() can now be used to modify the
max-restarts value at runtime. in both cases, the default is 11.
