Configuration files in system tests which require some variables (e.g.
port numbers) filled in during test setup, can now use jinja2 templates
when `jinja2` python package is available.
Any `*.j2` file found within the system test directory will be
automatically rendered with the environment variables into a file
without the `.j2` extension by the pytest runner. E.g.
`ns1/named.conf.j2` will become `ns1/named.conf` during test setup. To
avoid automatic rendering, use `.j2.manual` extension and render the
files manually at test time.
New `templates` pytest fixture has been added. Its `render()` function
can be used to render a template with custom test variables. This can be
useful to fill in different config options during the test. With
advanced jinja2 template syntax, it can also be used to include/omit
entire sections of the config file rather than using `named1.conf.in`,
`named2.conf.in` etc.

Coverity Scan reported a new issue for the ksr system test. There
is allegedly a null pointer dereference (FORWARD_NULL) in check_keys().
This popped up because previously we set 'retired' to 0 in case of
unlimited lifetime, but we changed it to None.
It is actually a false positive, because if lifetime is unlimited
there will be only one key in 'keys'.
However, the code would be better if we always initialized 'active'
and if it is not the first key and retired is set, set the successor
key's active time to the retire time of the predecessor key.

The test_ksr_twotwone may fail if the key id is shorter than 5 digits.
Add a leading space to the expected strings which start with the key
tag to avoid the issue.

While this file is no longer created / used in the main branch, it may

The pytest collection mechanism has been overhauled in pytest 8.0.0,
resulting in a different node tree when collecting the tests. Ensure the
paths / names we're using that are derived from the node tree are
consistent across different pytest versions.
Particularly, this has affected the convenience symlink name (which is
supposed to be in the form of e.g. dns64_sh_dns64 for the dns64 module
and tests_sh_dns64.py module) and the test name that's logged at the
start of the test, which is supposed to include the system test
directory relative to the root system test directory as well as the
module name (e.g. dns64/tests_sh_dns64.py).

When working with key timestamps, ensure we correctly set the UTC
timezone in order for the tests to work consistently regardless of the
local time setting.

Enforcing pylint standards and default for our test code seems
counter-productive. Since most of the newly added code are tests or is
test-related, encountering these checks rarely make us refactor the code
in other ways and we just disable these checks individually. Code that
is too complex or convoluted will be pointed out in reviews anyways.

It is possible that the zone is not yet fully signed because it is
signed in batches. Retry the AXFR and verify command a couple of times.

If a function is expected to assert / raise on failure (rather than
return boolean), its name should start with "check_".
(cherry picked from commit 67957d1f54)
Move all test cases from tests.sh to tests_ksr.py. The only test that
is not moved is the check that key id's match expected keys. The
shell-based system test checks two earlier set environment variables
against each other that has become redundant in the pytest variant,
because we now check the signed key response against a list of keys
and for each key we take into account the timing metadata. So we
already ensure that each published key is in the correct key bundle.

Write initial pytest kasp library. This contains everything that is
required for testing Offline KSK functionality with pytest.
This includes:
- addtime: adding a value to a timing metadata
- get_timing_metdata: retrieve timing metadata from keyfile
- get_metadata/get_keystate: retrieve metadata from statefile
- get_keytag: retrieve keytag from base keyfile string
- get_keyrole: get key role from statefile
- dnskey_equals: compare DNSKEY record from file against a string
- cds_equals: compare CDS derived from file against a string
- zone_is_signed: wait until a zone is completely signed
- dnssec_verify: verify a DNSSEC signed zone with dnssec-verify
- check_dnssecstatus: check rndc dnssec -status output
- check_signatures: check that signatures for a given RRset are correct
- check_dnskeys: check that the published DNSKEY RRset is correct
- check_cds: check that the published CDS RRset is correct
- check_apex: check SOA, DNSKEY, CDNSKEY, and CDS RRset
- check_subdomain: check an RRset below the apex

CookieOption with new .server/.client attributes (rather than .data) was
added to dnspython. Adjust the code to use the new attributes if
available and fall back to the old code for dnspython<2.7.0
compatibility.

In a multi-signer setup, removing DNSKEY records from the zone should
not be treated as a key that previously exists in the keyring, thus
blocking the keymgr. Add a test case to make sure.
(cherry picked from commit 5f552293d7)
Test that if a key to be purged is in the keyring, it does not
prevent the keymgr from running. Normally a key that is in the keyring
should be available again on the next run, but that is not true for
a key that can be purged.
In addition, fix some wait_for_log calls, by adding the missing
'|| ret=1' parts.
(cherry picked from commit a2317425bc)
Some test cases were working but for the wrong reasons. These started
to fail when I implemented the first approach for #4763, where the
existence of a DNSKEY together with an empty keyring is suspicious and
would prevent the keymgr from running.
These are:
1. kasp: The multisigner-model2.kasp zone has ZSKs from other providers
in the zone, but not yet its own keys. Pregenerate signing keys and
add them to the unsigned zone as well.
2. kasp: The dynamic-signed-inline-signing.kasp zone has a key generated
and added in the raw version of the zone. But the key file is stored
outside the key-directory for the given zone. Add '-K keys' to the
dnssec-keygen command.

Prior to running the keymgr, first make sure that existing keys
are present in the new keylist. If not, treat this as an operational
error where the keys are made offline (temporarily), possibly unwanted.
(cherry picked from commit 5fdad05a8a)
In this specific case the key files are temporary unavailable, for
example because of an operator error, or a mount failure). In such
cases, BIND should not try to roll over these keys.

This commit ensures that the port is set before attempting a UDP
query. Before that a situation could appear when previous query have
completed over a different transport (that uses a dedicated port) and
then a UDP query will be attempted over the port of the previous
transport.
(cherry picked from commit e390ed4421)
The dns_dispatch_add() function registers the 'resp' entry in
'disp->mgr->qids' hash table with 'resp->port' being 0, but in
tcp_recv_success(), when looking up an entry in the hash table
after a successfully received data the port is used, so if the
local port was set (i.e. it was not 0) it fails to find the
entry and results in an unexpected error.
Set the 'resp->port' to the given local port value extracted from
'disp->local'.
