The ADB hashmaps are stored in extra memory contexts, so the hash
tables are excluded from the overmem accounting. The new memory
context was unnamed, give it a proper name.
Same thing has happened with extra memory context used for named
global log context - give the extra memory context a proper name.

Set the DS state after issuing 'rndc dnssec -checkds'. If the DS
was published, it should go in RUMOURED state, regardless whether it
is already safe to do so according to the state machine.
Leaving it in HIDDEN (or if it was magically already in OMNIPRESENT or
UNRETENTIVE) would allow for easy shoot in the foot situations.
Similar, if the DS was withdrawn, the state should be set to
UNRETENTIVE. Leaving it in OMNIPRESENT (or RUMOURED/HIDDEN)
would also allow for easy shoot in the foot situations.

Artifacts of the "stress" jobs in GitLab CI are used for generating the
QA summary for a given set of releases. It happened in the past that
these artifacts were purged before the QA summary was prepared,
unnecessarily prolonging the release process. A complete set of
artifacts from all such jobs for a single pipeline should be less than 1
GB in size, so extend their lifetime from one day to one week as a more
reasonable compromise between availability and disk space usage. (Note:
these jobs are also run in scheduled pipelines, but that is expected to
be acceptable in the context of artifact lifetime.)
Artifacts of the "release" jobs in GitLab CI are what we eventually
publish on the FTP server. It happened in the past that these artifacts
were purged before we copied them to their destination, unnecessarily
prolonging the release process, even though we usually press the "Keep"
button for the "release" jobs manually to keep them around indefinitely
(as they are the source of what we publish in other places). Since
there is only one "release" job per tag pipeline and its artifacts only
take up tens of megabytes of space, keep the artifacts of the "release"
jobs around indefinitely by default.

This commit ensures that BIND and supplementary tools still can be
built on newer versions of DragonFly BSD. It used to be the case, but
somewhere between versions 6.2 and 6.4 the OS developers rearranged
headers and moved some function definitions around.
Before that the fact that it worked was more like a coincidence, this
time we, at least, looked at the related man pages included with the
OS.
No in depth testing has been done on this OS as we do not really
support this platform - so it is more like a goodwill act. We can,
however, use this platform for testing purposes, too. Also, we know
that the OS users do use BIND, as it is included in its ports
directory.
Building with './configure' and './configure --without-jemalloc' have
been fixed and are known to work at the time the commit is made.

It is allowed to point parental-agents to a resolver. Therefore, the
RD bit should be set on requests.
Upon receiving a DS response, ensure that the message has either the
AA or the RA bit set.
(cherry picked from commit e34722ed43)
Add a test case for a server that uses a resolver as an parental-agent.
We need two root servers, ns1 and ns10, one that delegates to the
'checkds' tld with the DS published (ns2), and one that delegates to
the 'checkds' tld with the DS removed (ns5). Both root zones are
being setup in the 'ns1/setup.sh' script.
We also need two resolvers, ns3 and ns8, that use different root hints
(one uses ns1 address as a hint, the other uses ns10).
Then add the checks to test_checkds.py is similar to the existing tests.
Update 'types' because for zones that have the DS withdrawn (or to be
withdrawn), the CDS and CDNSKEY records should not be published and
thus should not be in the NSEC bitmap.
(cherry picked from commit 0b9a9f9955)
The write node lock needs to be held when setting node->wild in
add_wildcard_magic except when being called from loading_addrdataset
which is used to load the zone without locking during its initial
load.
(cherry picked from commit 81c24b8da2)
Return 'isc_result_t' type value instead of 'bool' to indicate
the actual failure. Rename the function to something not suggesting
a boolean type result. Make changes in the places where the API
function is being used to check for the result code instead of
a boolean value.

Detaching the views in the zone_shutdown() could lead to
lock-order-inversion between adb->namelocks[bucket], adb->lock,
view->lock and zone->lock. Detach the views outside of the section that
zone-locked.

BIND 9.16 needs Python and PLY packages for configure to succeed.
Unless we want to tweak the build script to exclude python, we need to
add python3-ply package to the CodeQL configuration.

If the OpenSSL SHA1_{Init,Update,Final} API is still available, use it.
The API has been deprecated in OpenSSL 3.0, but it is significantly
faster than EVP_MD API, so make an exception here and keep using it
until we can't.
(cherry picked from commit 25db8d0103)
Instead of going through another layer, use OpenSSL EVP_MD API directly
in the isc_iterated_hash() implementation. This shaves off couple of
microseconds in the microbenchmark.

The reference counting and isc_timer_attach()/isc_timer_detach()
semantic are actually misleading because it cannot be used under normal
conditions. The usual conditions under which is timer used uses the
object where timer is used as argument to the "timer" itself. This
means that when the caller is using `isc_timer_detach()` it needs the
timer to stop and the isc_timer_detach() does that only if this would be
the last reference. Unfortunately, this also means that if the timer is
attached elsewhere and the timer is fired it will most likely be
use-after-free, because the object used in the timer no longer exists.
Remove the reference counting from the isc_timer unit, remove
isc_timer_attach() function and rename isc_timer_detach() to
isc_timer_destroy() to better reflect how the API needs to be used.
The only caveat is that the already executed event must be destroyed
before the isc_timer_destroy() is called because the timer is no longet
attached to .ev_destroy_arg.

The isc_task_purge() and isc_task_purgerange() were now unused, so sweep
the task.c file. Additionally remove unused ISC_EVENTATTR_NOPURGE event
attribute.
(cherry picked from commit c17eee034b)
When we are loading the zones, set the quantum to UINT_MAX, which makes
task_run process all tasks at once. After the zone loading is finished
the quantum will be dropped to 1 to not block server when we are loading
new zones after reconfiguration.
(cherry picked from commit 87c4c24cde)
Add isc_task_setquantum() function that modifies quantum for the future
isc_task_run() invocations.
NOTE: The current isc_task_run() caches the task->quantum into a local
variable and therefore the current event loop is not affected by any
quantum change.

Instead of searching for the events to purge, keep the list of scheduled
events on the timer list and purge the events that we have scheduled.
(cherry picked from commit 3f8024b4a2f12fcd28a9dd813b6f1f3f11d506f2)
The isc_task_purgerange() was walking through all events on the task to
find a matching task. Instead use the ISC_LINK_LINKED to find whether
the event is active.
Cleanup the related isc_task_unsend() and isc_task_unsendrange()
functions that were not used anywhere.
(cherry picked from commit 17aed2f895)
When we change the view in the view->managed_keys, we never commit the
change, keeping the previous view possibly attached forever.
Call the dns_zone_setviewcommit() immediately after changing the view as
we are detaching the previous view anyway and there's no way to recover
from that.
(cherry picked from commit 7e8b53720d)
The .view (and possibly .prev_view) would be kept attached to the
removed zone until the zone is fully removed from the memory in
zone_free(). If this process is delayed because server is busy
something else like doing constant `rndc reconfig`, it could take
seconds to detach the view, possibly keeping multiple dead views in the
memory. This could quickly lead to a massive memory bloat.
Release the views early in the zone_shutdown() call, and don't wait
until the zone is freed.
