"kyua report-html" command in CI generates more than two pages of output
to stdout, which is nothing but which HTML pages Kyua generated, e.g.:
Generating kyua_html/context.html
Generating kyua_html/lib_dns_tests_acl_test_main.html
...
Generating kyua_html/lib_ns_tests_query_test_main.html
Generating kyua_html/report.css
Generating kyua_html/index.html
This is seldomly useful and requires the user to scroll three pages
upwards to get to unit test results.
Any CI job:

Run this check only when in Git repository, because run.sh produces the

The ISC SPNEGO implementation is based on mod_auth_kerb code. When
CVE-2006-5989 was disclosed, the relevant fix was not applied to the
BIND 9 codebase, making the latter vulnerable to the aforementioned flaw
when "tkey-gssapi-keytab" or "tkey-gssapi-credential" is set in
named.conf.
The original description of CVE-2006-5989 was:
Off-by-one error in the der_get_oid function in mod_auth_kerb 5.0
allows remote attackers to cause a denial of service (crash) via a
crafted Kerberos message that triggers a heap-based buffer overflow
in the component array.
Later research revealed that this flaw also theoretically enables remote
code execution, though achieving the latter in real-world conditions is
currently deemed very difficult.
This vulnerability was responsibly reported as ZDI-CAN-12302 ("ISC BIND
TKEY Query Heap-based Buffer Overflow Remote Code Execution
Vulnerability") by Trend Micro Zero Day Initiative.
In DNS Flag Day 2020, the development branch started setting the
IP_DONTFRAG option on the UDP sockets. It turned out, that this
code was incomplete leading to dropping the outgoing UDP packets.
Henceforth this commit rolls back this setting until we have a
proper fix that would send back empty response with TC flag set.

The USE_OPENSSL constraint in dh_test does not seems to be necessary
anymore, the test runs with PKCS#11 as well.

Make sure lib/dns/tests/dnstap_test returns an exit code that indicates
a skipped test when dnstap is not enabled.
(cherry picked from commit c286341703)
BIND 9.17 changed exit code of skipped test to meet Automake
expectations in fa505bfb0e. BIND 9.16 was
not rewritten to Automake, but for consistency reasons, the same
SKIPPED_TEST_EXIT_CODE preprocessor macro is used (though the actual
exit code differs from the one in BIND 9.17).
(cherry picked from commit fa505bfb0e)
Descriptions of UNTESTED and SKIPPED system test results are very
similar to one another and it may be confusing when to pick one and
when the other. Merging these two system test results removes the
confusion.

As libssl depends on libcrypto, -lssl needs to precede -lcrypto in
linker invocations or else the build will fail with static OpenSSL
libraries. Adjust m4/ax_check_openssl.m4 to prevent this issue from
getting triggered when pkg-config files for OpenSSL are not available.
(cherry picked from commit 9223c7d599)
The only reason for including the gssapi.h from the dst/gssapi.h header
was to get the typedefs of gss_cred_id_t and gss_ctx_id_t. Instead of
using those types directly this commit introduces dns_gss_cred_id_t and
dns_gss_ctx_id_t types that are being used in the public API and
privately retyped to their counterparts when we actually call the gss
api.
This also conceals the gssapi headers, so users of the libdns library
doesn't have to add GSSAPI_CFLAGS to the Makefile when including libdns
dst API.
