  bind-9-18-12

  [Test Plan]

  DEP-8 Tests:

  simpletest - Confirms bind9 daemon starts successfully and dig can
  find 127.0.0.1 through the default setup of bind9

  zonetest - Added in this update, currently in lunar. Confirms the
  functionality of named and bind9 by creating a local DNS zone and
  domain, and having dig look it up

  validation - This test is provided by Debian and consistently fails
  both before and after the update due to several issues. It is marked
  as flaky, and does not block autopkgtest passing overall

  Bug fix tests:

  Test for LP: #1258003 fix:
  # lxc launch images:ubuntu/{kinetic, jammy} test-bind9
  # lxc exec test-bind9
  # apt update && apt dist-upgrade -y
  # apt install dnsutils -y
  # dig google.com +nssearch +tcp
  - Before the update this leads to a crash ending in "Aborted (core dumped)" without showing all addresses while after it will show that there was a communication error with addresses it did not get a response from and finish running through all addresses

  Test for LP: #1970252 fix:
  # lxc launch images:ubuntu/{kinetic, jammy} test-bind9
  # lxc exec test-bind9
  # apt update && apt dist-upgrade -y
  # apt install dnsutils -y
  # dig +nssearch isc.org
  - Before the update this also leads to a crash ending in "Aborted (core dumped)" after failing to get a response from an ipv6 address while after it will again show that there was a communication error with addresses it did not get a response from

  Test for LP: #2006972 fix:
  # lxc launch images:ubuntu/jammy test-bind9
  # lxc exec test-bind9 bash
  # apt update && apt dist-upgrade
  # apt install bind9
  # cat <<EOF >/etc/bind/named.conf.options
  options {
          directory "/var/cache/bind";
          dnssec-validation auto;
          listen-on-v6 { any; };
  };
  plugin query "filter-aaaa.so" {
          filter-aaaa-on-v4 yes;
  };
  EOF
  # named-checkconf
  - Before the update this fails since named is looking for filter-aaaa.so in /usr/lib/x86_64-linux-gnu/named instead of the correct location /usr/lib/x86_64-linux-gnu/bind. After the fix named-checkconf succeeds.

  [Regression Potential]

  Upstream has an extensive build and integration test suite. So
  regressions would likely arise from a change in interaction with
  Ubuntu-specific integrations. Alternatively, regressions may arise for
  users due to behavior changes from the many bug fixes and minor
  feature updates.
