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)
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.

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)
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.

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.
(cherry picked from commit cd04b89dba85781c194f22ce6fe358c972a14758)
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)
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.)
(cherry picked from commit 05d78671bb)
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)
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)
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)
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)
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)
In order to protect from a malicious DNS client that sends many
queries with a SIG(0)-signed message, add a quota of simultaneously
running SIG(0) checks.
This protection can only help when named is using more than one worker
threads. For example, if named is running with the '-n 4' option, and
'sig0checks-quota 2;' is used, then named will make sure to not use
more than 2 workers for the SIG(0) signature checks in parallel, thus
leaving the other workers to serve the remaining clients which do not
use SIG(0)-signed messages.
That limitation is going to change when SIG(0) signature checks are
offloaded to "slow" threads in a future commit.
The 'sig0checks-quota-exempt' ACL option can be used to exempt certain
clients from the quota requirements using their IP or network addresses.
The 'sig0checks-quota-maxwait-ms' option is used to define a maximum
amount of time for named to wait for a quota to appear. If during that
time no new quota becomes available, named will answer to the client
with DNS_R_REFUSED.
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.
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.
