If there are duplicate key ids across multiple algorithms expected
output is no met. We have fixed this in on main but decided to not
back port the fix as it will change the statistics channel output.
This change detects when there are duplicate key id across algorithms
as skips the sub test.

The tcp Pytest on OpenBSD fairly reliably fails when receive_tcp()
on a socket is attempted:
> (response, rtime) = dns.query.receive_tcp(sock, timeout())
tests-tcp.py:50:
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
/usr/local/lib/python3.9/site-packages/dns/query.py:659: in receive_tcp
ldata = _net_read(sock, 2, expiration)
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
sock = <socket.socket [closed] fd=-1, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=6>
count = 2, expiration = 1662719959.8106785
def _net_read(sock, count, expiration):
"""Read the specified number of bytes from sock. Keep trying until we
either get the desired amount, or we hit EOF.
A Timeout exception will be raised if the operation is not completed
by the expiration time.
"""
s = b''
while count > 0:
try:

E socket.timeout: timed out
This is because the socket is already closed.
Bump the socket connection timeout to 10 seconds.

There was a ubsan error reporting an invalid value for interface_auto
(a boolean value cannot be 190) because it was not initialized. To
avoid this problem happening again, ensure the whole of the server
structure is initialized to zero before setting the (relatively few)
non-zero elements.
It is possible to bypass Response Rate Limiting (RRL)
`responses-per-second` limitation using specially crafted wildcard
names, because the current implementation, when encountering a found
DNS name generated from a wildcard record, just strips the leftmost
label of the name before making a key for the bucket.
While that technique helps with limiting random requests like
<random>.example.com (because all those requests will be accounted
as belonging to a bucket constructed from "example.com" name), it does
not help with random names like subdomain.<random>.example.com.
The best solution would have been to strip not just the leftmost
label, but as many labels as necessary until reaching the suffix part
of the wildcard record from which the found name is generated, however,
we do not have that information readily available in the context of RRL
processing code.
Fix the issue by interpreting all valid wildcard domain names as
the zone's origin name concatenated to the "*" name, so they all will
be put into the same bucket.

The zone 'retransfer3.' tests whether zones that 'rndc signing
-nsec3param' requests are queued even if the zone is not loaded.
The test assumes that if 'rndc signing -list' shows that the zone is
done signing with two keys, and there are no NSEC3 chains pending, the
zone is done handling the '-nsec3param' queued requests. However, it
is possible that the 'rndc signing -list' command is received before
the corresponding privatetype records are added to the zone (the records
that are used to retrieve the signing status with 'rndc signing').
This is what happens in test failure
https://gitlab.isc.org/isc-projects/bind9/-/jobs/2722752.
The 'rndc signing -list retransfer3' is thus an unreliable check.
It is simpler to just remove the check and wait for a certain amount
of time and check whether ns3 has re-signed the zone using NSEC3.

previously, if ns_clientmgr_create() failed, the interface was not
cleaned up correctly and an assertion or segmentation fault could
follow. this has been fixed.
The usage of xmlInitThreads() and xmlCleanupThreads() functions in
libxml2 is now marked as deprecated, and these functions will be made
private in the future.
Use xmlInitParser() and xmlCleanupParser() instead of them.

Having implicit inline-signing set for dnssec-policy when there is no
update policy is confusing, so lets make this explicit.

In several cases where IDNA2008 mappings do not exist whereas IDNA2003
mappings do, dig was failing to process the suplied domain name. Take a
backwards compatible approach, and convert the domain to IDNA2008 form,
and if that fails try the IDNA2003 conversion.

This should make sure that the memory context is not destroyed
before the memory pool, which is using the context.

YAML strings should be quoted if they contain colon characters.
Since IPv6 addresses do, we now quote the query_address and
response_address strings in all YAML output.

The dnstap query_message field was in some cases being filled in
with response messages, along with the response_message field.
The query_message field should only be used when logging requests,
and the response_message field only when logging responses.
There is no need for a release because this case was nearly impossible
to trigger (except for when 'sig-signing-type' was set to 0).

There is one case in 'dns_nsec3_activex()' where it returns but forgets
to detach the db node. Add the missing 'dns_db_detachnode()' call.
This case only triggers if 'sig-signing-type' (privatetype) is set to 0
(which by default is not), or if the function is called with 'complete'
is set to 'true' (which at this moment do not exist).

It might be reused if /etc/bind.keys exists, but failed correct parsing.
Release traces of previous parsing attempt of different data.
