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.

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.

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.
(cherry picked from commit c5588babaf)
the number of steps that can be followed in a CNAME chain
before terminating the lookup has been reduced from 16 to 11.
(this is a hard-coded value, but will be made configurable later.)

The question section should be present in the first AXFR/IXFR
response and in other QUERY responses unless no question was sent.
Issue a warning if the question section is not present.

Ensure all the variables are initialized when running the main function
of isctest module. This enables proper environment variables during test
script development when only conf.sh is sourced, rather than the script
being executed by the pytest runner.
(cherry picked from commit d7ace928b5)
Run the crypto support checks when initializing the isctest package and
save those results in environment variable. This removes the need to
repeatedly check for crypto operation support, as it's not something
that would change at test runtime.
(cherry picked from commit 25cb39b7fc)
Instead of invoking get_algorithms.py script repeatedly (which may yield
different results), move the algorithm configuration to an isctest
module. This ensures the variables are consistent across the entire test
run.
(cherry picked from commit 8302db407c)
The dst_lib_destroy() should be called only if dst_lib_init() was called
before. In named-checkconf, that is guarded by dst_cleanup variable
that was erroneously set to true by default. Set the dst_cleanup to
'false' by default.
(cherry picked from commit c54880e3fa)
Add a system test that sets TSIG fudge to 0, waits three seconds and
then sends signed message to the server. This tests the path where the
time difference between the client and the server is outside of the TSIG
fudge value.
(cherry picked from commit 8def0c3b12)
When automatic-interface-scan is disabled, the route socket was still
being opened. Add new API to connect / disconnect from the route socket
only as needed.
Additionally, move the block that disables periodic interface rescans to
a place where it actually have access to the configuration values.
Previously, the values were being checked before the configuration was
loaded.
(cherry picked from commit b26079fdaf)
The system tests were overriding the local locale by setting LANG to C.
This does not override the locale in case there are individual LC_<*>
variables like LC_CTYPE explicitly set.
Use LC_ALL=C instead which is the proper way of overriding all currently
set locales.
(cherry picked from commit 10147efc87)
Not all invocations had it, and this makes it more consistent with
dighost_warning. Also remove the conditional newline when not outputting
yaml

If bufsize overflows we will have an infinite loop. In practice
this will not happen unless we have made a coding error. Add an
INSIST to detect this condition.

Use a big zone and the slow transfer mode. Initiate a retransfer, wait
several seconds, then initiate a retransfer using a '-force' argument,
which should cancel the previous transfer and start a new one.
(cherry picked from commit e48f4e8101)
With this new optional argument if there is an ongoing zone
transfer it will be aborted before a new zone transfer is scheduled.
(cherry picked from commit 402ca316ae)
Update the CNAME chain test to correspond to the changed behavior,
because now named returns SERVFAIL when hitting the maximum query
restarts limit (e.g. happening when following a long CNAME chain).
In the current test auth will hit the limit and return partial data
with a SERVFAIL code, while the resolver will return no data with
a SERVFAIL code after auth returns SERVFAIL to it.
(cherry picked from commit 7751c7eca6)
The updatecheck-kskonly.secure zone is being used to test dynamic
updates while the KSK is offline. It ensures that the DNSKEY RRset
will retain the RRSIG record, while the updated data is being signed
with the currently active ZSK.
When walking through ZSK rollovers, ensure that the newest ZSK (ZSK3)
is published before doing the dynamic update, preventing timing
related test failures.
Also fix the test log line ($ZSK_ID3 was not yet created at the time
of logging).
(cherry picked from commit e874632488)
The key lifetime should no longer be adjusted if the key is being
retired earlier, for example because a manual rollover was started.
This would falsely be seen as a dnssec-policy lifetime reconfiguration,
and would adjust the retire/removed time again.
This also means we should update the status output, and the next
rollover scheduled is now calculated using (retire-active) instead of
key lifetime.
(cherry picked from commit 129973ebb0)
Check if the key lifetime is updated in the key files. Make sure the
inactive and removed timing metadata are adjusted accordingly.
(cherry picked from commit 2237895bb4)
View matching on an incoming query checks the query's signature,
which can be a CPU-heavy task for a SIG(0)-signed message. Implement
an asynchronous mode of the view matching function which uses the
offloaded signature checking facilities, and use it for the incoming
queries.
This is a tiny helper function which is used only once and can be
replaced with two function calls instead. Removing this makes
supporting asynchronous signature checking less complicated.
