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.

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 #defined constants because of RHEL 8 compiler doesn't consider
static const unsigned int to be constant.

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.

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.)

Instead of randomly using -1 or 1 as a failure status, properly utilize
the EXIT_FAILURE define that's platform specific (as it should be).
(cherry picked from commit76997983fde02d9c32aa23bda30b65f1ebd4178c)
Since the fatal() isn't a correct but rather abrupt termination of the
program, we want to skip the various atexit() calls because not all
memory might be freed during fatal() call, etc. Using _exit() instead
of exit() has this effect - the program will end, but no destructors or
atexit routines will be called.

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.
Not all invocations had it, and this makes it more consistent with
dighost_warning. Also remove the conditional newline when not outputting
yaml

this will not happen unless we have made a coding error. Add an
INSIST to detect this condition.

The times it takes to run tests CI vary significantly enough
that it makes hypothesis test reach their deadlines and fail randomly
marking the tests as flaky.
This commit disables the deadlines when running in CI.
(cherry picked from commit f55cacbbfd)
The most important being `dns_names` that generates dns.name.Name
objects based on given paramaters.
No guarantees are given when it comes the uniformity of generated
samples, however it plays nicely with the hypothesis' shrinking
algorithm.
Once we use hypothesis more widely (in at least one more test) this file
should be moved for it to be reused easily.
(cherry picked from commit 5d738cd9ed)
Check for more rcodes and various properties needed in the wildcard
test. Add a `name` module for various dns.name.Name operations (with
`prepend_label` function only now).
Expose `timeout` as a parameter of `query.tcp`/`query.udp`.
(cherry picked from commit e7d46ad8ba)
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)
In 9.18, 'inline-signing yes;' must also be configured explicitly for
zones using dnssec-policy without a configured 'allow-update' or
'update-policy'.
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)
bin/dig/dighost.c calls isc_nm_httpconnect. The timeout setting
(local_timeout) is passed as the 11th argument, but the function in
lib/isc/netmgr/http.c has the timeout argument as the 11th argument.
The 10th and 11th argument were reversed. This commit fixes that.
Thanks to Nicolas Dehaine for reporting and providing the fix.
Instead of relying on a specific order of the RR types in the databases
pick the first RR type as returned from the cache.
(cherry picked from commit 58f660cf2b)
Test that SIG(0) signer is NOT sent to the external socket for
authorization. It MUST NOT be considered a valid signature by
any chance.
Also check that the signer's name does not appear in authsock.pl
output.
kasp-max-types-per-name (named2.conf.in):
An unsigned zone with RR type count on a name right below the
configured limit. Then sign the zone using KASP. Adding a RRSIG would
push it over the RR type limit per name. Signing should fail, but
the server should not crash, nor end up in infinite resign-attempt loop.
kasp-max-records-per-type-dnskey (named1.conf.in):
Test with low max-record-per-rrset limit and a DNSSEC policy requiring
more than the limit. Signing should fail.
kasp-max-types-per-name (named1.conf.in):
Each RRSIG(covered type) is counted as an individual RR type. Test the
corner case where a signed zone, which is just below the limit-1,
adds a new type - doing so would trigger signing for the new type and
thus increase the number of "types" by 2, pushing it over the limit
again.
(cherry picked from commit 14e5230f897a178221b606c242b8fbcb357704aa)
Add two new masterformat tests that use signing. In the case of
'under-limit-kasp', the signing will keep the number of records in the
RRset under the limit. In the case of 'on-limit-kasp', the signing
will push the number of records in the RRset over the limit, because
of the added RRSIG record.
