BIND wasn't honoring option "deny-answer-aliases" when configured to
forward queries.
Before the fix it was possible for nameservers listed in "forwarders"
option to return CNAME answers pointing to unrelated domains of the
original query, which could be used as a vector for rebinding attacks.
The fix ensures that BIND apply filters even if configured as a forwarder
instance.
ORACLE MySQL 8.0 has dropped the my_bool type, so we need to reinstate
it back when compiling with that version or higher. MariaDB is still
keeping the my_bool type. The numbering between the two (MariaDB 5.x
jumped to MariaDB 10.x) doesn't make the life of the developer easy.

Most build/test job names already contain a "clang", "gcc", or "msvc"
prefix which indicates the compiler used for a given job. Apply that
naming convention to all build/test job names.

Multiple YAML keys have identical values for both TSAN unit test job
definitions. Extract these common keys to a YAML anchor and use it in
TSAN unit test job definitions to reduce code duplication.
(cherry picked from commit 84463f33bf)
Definitions of jobs running unit tests under TSAN contain an
"after_script" YAML key. Since the "unit_test_job" anchor is included
in those job definitions before "after_script" is defined, the
job-specific value of that key overrides the one defined in the included
anchor. This prevents "kyua report-html" from being run for TSAN unit
test jobs. Moving the invocation of "kyua report-html" to the "script"
key in the "unit_test_job" anchor is not acceptable as it would cause
the exit code of that command to determine the result of all unit test
jobs and we need that to be the exit code of "make unit". Instead, add
"kyua report-html" invocations to the "after_script" key of TSAN unit
test job definitions to address the problem without affecting other job
definitions.

Multiple YAML keys have identical values for both TSAN system test job
definitions. Extract these common keys to a YAML anchor and use it in
TSAN system test job definitions to reduce code duplication.
(cherry picked from commit a9aa295f1f)
Both "system_test_job" and "unit_test_job" YAML anchors contain a
"before_script" key. TSAN job definitions first specify their own value
of the "before_script" key and then include the aforementioned YAML
anchors, which results in the value of the "before_script" key being
overridden with the value specified by the included anchor. Given this,
remove "before_script" definitions specific to TSAN jobs as they serve
no practical purpose.
(cherry picked from commit 8ef01c7b50)
All assignments for the TSAN_OPTIONS variable are identical across the
entire .gitlab-ci.yml file. Define a global TSAN_OPTIONS_COMMON
variable and use it in job definitions to reduce code duplication.

The custom builds (oot, asan, tsan) were mostly built using Debian sid
amd64 image. The problem was that this image broke too easily, because
it's Debian "unstable" after all.
This commit introduces "base_image" that should be most stable with
extra bits on top (clang, coccinelle, cppcheck, ...). Currently, that
would be Debian buster amd64.
Other changes introduced by this commit:
* Change the default clang version to 10
* Run both ASAN and TSAN with both gcc and clang compilers
* Remove Clang Debian stretch i386 job

These are mostly false positives, the clang-analyzer FAQ[1] specifies
why and how to fix it:
> The reason the analyzer often thinks that a pointer can be null is
> because the preceding code checked compared it against null. So if you
> are absolutely sure that it cannot be null, remove the preceding check
> and, preferably, add an assertion as well.

(cherry picked from commit 262f087bcf)
There are several reason why remove Debian 8 from the CI:
* Debian 8 ("jessie") has been superseded by Debian 9 ("stretch").
* Regular security support updates have been discontinued as of
June 17th, 2018.
* Jessie LTS is supported from 17th June 2018 to June 30, 2020.
In other words, it's no longer officially supported by Debian security
team, but by the volunteer/paid contributor composed LTS team. And the
release will be discontinued in three months from now. We can use the
freed CI resources to bring new platforms or just to make the jobs run a
bit faster.
(cherry picked from commit 75f46cc3d1)
The environment variable MAKE has been replaced with MAKE_COMMAND,
because overriding MAKE variable also changed the definition of the MAKE
inside the Makefiles, and we want only a single wrapper around the whole
build process.
Previously, setting `MAKE` to `bear make` meant that `bear make` would
be run at every nested make invocation, which messed up the upcoming
automake transition as compile_commands.json would be generated in every
subdirectory instead of just having one central file at the top of the
build tree.

All jobs now use solely the newer needs configuration to declare
dependencies between jobs:
needs:
- job: <foo>
artifacts: true
instead of combination of dependencies and needs which is deprecated.
This change completely unbundles the stages (alas the stages still needs
to stay because the job graph has to stay acyclic between the stages).
(cherry picked from commit 66ba808c1b)
When unit test fails, core file is created. Kyua's 'debug' command can
run GDB on it and provide backtrace. Unfortunately Kyua is picky about
location of these core files we opt to use custom Kyua fork and copy
core files from Kyua working directory to source tree and make it
available in GitLab.

./configure needs util/check-make-install.in to be present in the source
directory in order to complete successfully. Make sure this file is
included in source tarballs created from the repository.
The libisc LIBINTERFACE bump for 9.11.17 is unnecessary.
A lot of headers were altered but the ABI tool did not report anything.
Trust the ABI tool on this and decrement LIBINTERFACE and increment
LIBREVISION.
Michal caught at the last moment that a CHANGES entry did
not have a GitLab issue/mr reference. This check was omitted from
the release process documentation. The wiki is updated and the
CHANGES file is updated in this commit.
Bumped the version file and added release line in CHANGES.
API files:
- lib/bind9/api:
No changes because only changes in comments.
- lib/dns/api:
Increment LIBINTERFACE because of the added field structure in
dns_struct_update.
- lib/isc/api:
Increment LIBINTERFACE because of the PKCS#11 replacement.
- lib/isccc/api:
No changes because no source code changes.
- lib/isccfg/api:
Increment LIBREVISION because of minor source code changes.
- lib/lwres/api:
No changes because no source code changes.
I decided no changes to README.md or the release notes were necessary.
Perflab graphs look sane.
