A dns_rpz_unref_rpzs() call is missing when taking the 'goto unlock;'
path on shutdown, in order to compensate for the earlier
dns_rpz_ref_rpzs() call.
Move the dns_rpz_ref_rpzs() call after the shutdown check.

When shutting down, or when dns_dbiterator_current() fails, 'node'
shouldn't be detached, because it is NULL at that point.
(cherry picked from commit d36728e42f)
When shutting down, the cleanup path should not try to destroy
'newnodes', because it is NULL at that point.
Introduce another label for the "shuttingdown" scenario.
(cherry picked from commit 975d16230b)
The dns_rpz_zones structure was using .refs and .irefs for strong and
weak reference counting. Rewrite the unit to use just a single
reference counting + shutdown sequence (dns_rpz_destroy_rpzs) that must
be called by the creator of the dns_rpz_zones_t object. Remove the
reference counting from the dns_rpz_zone structure as it is not needed
because the zone objects are fully embedded into the dns_rpz_zones
structure and dns_rpz_zones_t object must never be destroyed before all
dns_rpz_zone_t objects.
The dns_rps_zones_t reference counting uses the new ISC_REFCOUNT_TRACE
capability - enable by defining DNS_RPZ_TRACE in the dns/rpz.h header.
Additionally, add magic numbers to the dns_rpz_zone and dns_rpz_zones
structures.

This adds an island of trust that is reachable from the root
where the trust anchors are added to island.conf.
This add an island of trust that is not reachable from the root
where the trust anchors are added to private.conf.
(cherry picked from commit 41bdb5b9fe)
When there are multiple managed trust anchors we need to know the
name of the trust anchor that is failing. Extend the error message
to include the trust anchor name.

Occasionally, the allotted 10 seconds for the "running" line to appear
in log after named is started proved insufficient in CI, especially
during increased load. Give named up to 60 seconds to start up to
mitigate this issue.
(cherry picked from commit b8bb4233e8)
The script will start the named process configured as both an
authoritative and recursive server for each pairwise ./configure
configuration. The test is considered successful if the named process
runs until the 5-second timeout is triggered, and there is no named.lock
file present, indicating that named did not crash on shutdown.

Previously, the RPZ updates ran quantized on the main nm_worker loops.
As the quantum was set to 1024, this might lead to service
interruptions when large RPZ update was processed.
Change the RPZ update process to run as the offloaded work. The update
and cleanup loops were refactored to do as little locking of the
maintenance lock as possible for the shortest periods of time and the db
iterator is being paused for every iteration, so we don't hold the rbtdb
tree lock for prolonged periods of time.
(cherry picked from commit f106d0ed2b)
Previously dns_rpz_add() were passed dns_rpz_zones_t and index to .zones
array. Because we actually attach to dns_rpz_zone_t, we should be using
the local pointer instead of passing the index and "finding" the
dns_rpz_zone_t again.
Additionally, dns_rpz_add() and dns_rpz_delete() were used only inside
rpz.c, so make them static.
(cherry picked from commit b6e885c97f)
Do a general cleanup of lib/dns/rpz.c style:
* Removed deprecated and unused functions
* Unified dns_rpz_zone_t naming to rpz
* Unified dns_rpz_zones_t naming to rpzs
* Add and use rpz_attach() and rpz_attach_rpzs() functions
* Shuffled variables to be more local (cppcheck cleanup)

Add an extra job for a build from tarball, but without sphinx-build and
enable RUN_MAKE_INSTALL to check that man pages were generated and
installed.
Disable the RUN_MAKE_INSTALL on the systems without sphinx-build (sid).
(cherry picked from commit 8f2e1e15cc)
We don't need them in the repo, it's sufficient if we pregenerate them
while preparing the tarball. That way we don't have overhead while
modifying them but they are still available for installations without
Sphinx.
I assume that this will make rebases and cherry-picks across branches
easier, with less trial and error churn required in the CI.
It's implemented in the way that we build the manpages only when we
either have pregenerated pages available at the configure time or
sphinx-build is installed and working.

libuv support for receiving multiple UDP messages in a single system
call (recvmmsg()) has been tweaked several times between libuv versions
1.35.0 and 1.40.0. Mixing and matching libuv versions within that span
may lead to assertion failures and is therefore considered harmful, so
try to limit potential damage be preventing users from mixing libuv
versions with distinct sets of recvmmsg()-related flags.
(cherry picked from commit 735d09bffe)
The implementation of UDP recvmmsg in libuv 1.35 and 1.36 is
incomplete and could cause assertion failure under certain
circumstances.
Modify the configure and runtime checks to report a fatal error when
trying to compile or run with the affected versions.

isc_bind9 was a global bool used to indicate whether the library
was being used internally by BIND or by an external caller. external
use is no longer supported, but the variable was retained for use
by dyndb, which needed it only when being built without libtool.
building without libtool is *also* no longer supported, so the variable
can go away.

Send the test message from ns3 to ns2 instead of ns2 to ns3 as ns2
is started first and therefore the test doesn't have to wait on the
resend of the the NOTIFY message to be successful.
(cherry picked from commit e7e1f59a3a)
Move and give unique names to the dns_db_t, dns_dbnode_t and
dns_dbversion_t pointers, so they have global scope and therefore
are visible to cleanup. Unique names are not strictly necessary,
as none of the functions involved call each other.
Change free_db to handle NULL pointers and also an optional
(dns_dbversion_t **).
In match_keyset_dsset and free_keytable, ki to be handled
differently to prevent a false positive NULL pointer dereference
warning from scan.
In formatset moved dns_master_styledestroy earlier and freed
buf before calling check_result to prevent memory leak.
In append_new_ds_set freed ds on the default path before
calling check_result to prevent memory leak.

dnssec-cds failed to cleanup on non error paths which meant that
the OpenSSL libraries could not cleanup properly.

Instead of using an extra rarely-used paramater to dns_clientinfo_init()
to set ECS information for a client, this commit adds a function
dns_clientinfo_setecs() which can be called only when ECS is needed.
(cherry picked from commit ff3fdaa424)
the nsupdate system test was intermittently failing due to the update
quota not being exceeded when it should have been. this is most likely
a timing issue: the client is sending updates too slowly, or the server
is processing them too quickly, for the quota to fill. this commit
attempts to make that the failure less likely by increasing the number
of update transactions from 10 to 20.

when generating a key, if a DH key already existed for the same
name, a spurious warning message was generated saying "bad key
type". this is fixed.

Following deleting the root trust anchor and reconfiguring the
server it takes some time to for trust anchor to appear in 'rndc
managed-keys status' output. Retry several times.
