Since CVE-2023-50868 does not have a dedicated fix in BIND 9, mention
its CVE identifier in the CHANGES entry for CVE-2023-50387 (KeyTrap),
which accompanied the code change that addresses both of these
vulnerabilities.
(cherry picked from commit 2fd20bbaf5)
lib/dns/validator.c:findnsec3proofs failed to disassociate the
temporary rdataset returned by dns_ncache_current on all paths.
(cherry picked from commit dc94f42209)
We were missing a test where a single owner name would have multiple
types with a different case. The generated RRSIGs and NSEC records will
then have different case than the signed records and message parser have
to cope with that and treat everything as the same owner.
(cherry picked from commit 14e435b814)
The case insensitive matching in isc_ht was basically completely broken
as only the hashvalue computation was case insensitive, but the key
comparison was always case sensitive.

When running `make check` on a platform which has older (but still
supported) pytest, e.g. 3.4.2 on EL8, the junit to trs conversion would
fail because the junit format has different structure. Make the junit
XML processing more lenient to support both the older and newer junit
XML formats.

The ditch.pl script is used to generate burst traffic without waiting
for the responses. When running other tests in parallel, this can result
in a ephemeral port clash, since the ditch.pl process closes the socket
immediately. In rare occasions when the message ID also clashes with
other tests' queries, it might result in an UnexpectedSource error from
dnspython.
Use a dedicated port EXTRAPORT8 which is reserved for each test as a
source port for the burst traffic.
(cherry picked from commit 339fa5690a)
Stop the cname_and_other_data processing if we already know that the
result is true. Also, we know that CNAME will be placed in the priority
headers, so we can stop looking for CNAME if we haven't found CNAME and
we are past the priority headers.
(cherry picked from commit 3f774c2a8a)
Mark the infrastructure RRTypes as "priority" types and place them at
the beginning of the rdataslab header data graph. The non-priority
types either go right after the priority types (if any).
(cherry picked from commit 3ac482be7f)
The cachedb was missing piece of code (already found in zonedb) that
would make lookups in the slabheaders to miss the RRSIGs for CNAME if
the order of CNAME and RRSIG(CNAME) was reversed in the node->data.
(cherry picked from commit 5070c7f5c7)
"A parental agent is the entity that is allowed to change a zone's
delegation information" is untrue, because it is possible to use some
hidden server or a validating resolver.
Also the new text makes it more clear that named sends DS queries to
these servers.
(cherry picked from commit 604f8e7797)
Use the (1 << N) form for defining the flags, in order to avoid
errors like the one fixed in the previous commit.
Also convert the definitions to an enum, as done in some of our
recent refactoring work.
(cherry picked from commit 0d7c7777da)
The DNS_GETDB_STALEFIRST flag is defined as 0x0C, which is the
combination of the DNS_GETDB_PARTIAL (0x04) and the
DNS_GETDB_IGNOREACL (0x08) flags (0x04 | 0x08 == 0x0C) , which is
an obvious error.
All the flags should be power of two, so they don't interfere with
each other. Fix the DNS_GETDB_STALEFIRST flag by setting it to 0x10.
