there was no system test that exercised 'rndc recursing'; a
simple one has now been added; it confirms that the number of
recursing clients reported by 'rndc stats' is in agreement with
the list returned by 'rndc recursing'.
Otherwise the "statistics-channels" option in doc/misc/options and
doc/man/named.conf.5in is marked as "not configured" (contrary to what
we have in release tarballs as they were build on a different image that
has libjson-c and libxml2 in it).
Caused by #4895 that made the option dependant on libjson-c or libxml2
presence in the build image.
When running shotgun tests on tagged releases, the increased number of
jobs may cause the shotgun pipeline to take longer than 50 minutes to
finish.

Prior to doing key management, BIND 9 will check if the key files on disk match the expected keys. If key files for previously observed keys have become unavailable, this will prevent the internal key manager from running.

In a multi-signer setup, removing DNSKEY records from the zone should
not be treated as a key that previously exists in the keyring, thus
blocking the keymgr. Add a test case to make sure.
Test that if a key to be purged is in the keyring, it does not
prevent the keymgr from running. Normally a key that is in the keyring
should be available again on the next run, but that is not true for
a key that can be purged.
In addition, fix some wait_for_log calls, by adding the missing
'|| ret=1' parts.
Some test cases were working but for the wrong reasons. These started
to fail when I implemented the first approach for #4763, where the
existence of a DNSKEY together with an empty keyring is suspicious and
would prevent the keymgr from running.
These are:
1. kasp: The multisigner-model2.kasp zone has ZSKs from other providers
in the zone, but not yet its own keys. Pregenerate signing keys and
add them to the unsigned zone as well.
2. kasp: The dynamic-signed-inline-signing.kasp zone has a key generated
and added in the raw version of the zone. But the key file is stored
outside the key-directory for the given zone. Add '-K keys' to the
dnssec-keygen command.
Prior to running the keymgr, first make sure that existing keys
are present in the new keylist. If not, treat this as an operational
error where the keys are made offline (temporarily), possibly unwanted.
In this specific case the key files are temporary unavailable, for
example because of an operator error, or a mount failure). In such
cases, BIND should not try to roll over these keys.
This commit ensures that the port is set before attempting a UDP
query. Before that a situation could appear when previous query have
completed over a different transport (that uses a dedicated port) and
then a UDP query will be attempted over the port of the previous
transport.
Closes: #4984.

In two places, after linking the client to the manager's

function, the query.c module fails to unlink it on error
paths. Fix the bugs by unlinking the client from the list.

Rename check_recursionquota() to acquire_recursionquota(), and
implement a new function called release_recursionquota() to
reverse the action. It helps with decreasing code duplication.

"recursing-clients" list using the check_recursionquota()

Also make sure that unlinking happens before detaching the
client's handle, as it is the logically correct order, e.g.
in case if it's the last handle and ns__client_reset_cb()
can be called because of the detachment.
The dns_zone_getxfrintime() function fails to lock the zone before
accessing its 'xfrintime' structure member, which can cause a data
race between soa_query() and the statistics channel. Add the missing
locking/unlocking pair, like it's done in numerous other similar
functions.

The outgoing UDP sockets enabled `SO_REUSEADDR` that allows sharing of the UDP sockets, but with one big caveat - the socket that was opened the last would get all traffic. The dispatch code would ignore the invalid responses in the dns_dispatch, but this could lead to unexpected results.
Merge branch 'ondrej/fix-outgoing-UDP-port-selection' into 'main'
See merge request isc-projects/bind9!9569
Currently, the outgoing UDP sockets have enabled
SO_REUSEADDR (SO_REUSEPORT on BSDs) which allows multiple UDP sockets to
bind to the same address+port. There's one caveat though - only a
single (the last one) socket is going to receive all the incoming
traffic. This in turn could lead to incoming DNS message matching to
invalid dns_dispatch and getting dropped.
Disable setting the SO_REUSEADDR on the outgoing UDP sockets. This
needs to be done explicitly because `uv_udp_open()` silently enables the
option on the socket.
When matching the received Query ID in the TCP connection,
an invalid received Query ID can very rarely cause assertion
failure.

When matching the TCP dispatch responses, we should skip the responses
that do not belong to our TCP connection. This can happen with faulty
upstream server that sends invalid QID back to us.
The dns_dispatch_add() function registers the 'resp' entry in
'disp->mgr->qids' hash table with 'resp->port' being 0, but in
tcp_recv_success(), when looking up an entry in the hash table
after a successfully received data the port is used, so if the
local port was set (i.e. it was not 0) it fails to find the
entry and results in an unexpected error.
Set the 'resp->port' to the given local port value extracted from
'disp->local'.

The configuration option `print-time` can now be set to `iso8601-tzinfo` in order to use the ISO 8601 timestamp with timezone information when logging. This is used as a default for `named -g`.
Closes#4963
Merge branch '4963-provide-timezone-information-in-log-timestamps' into 'main'
See merge request isc-projects/bind9!9563
This commit adds support for timestamps in iso8601 format with timezone
when logging. This is exposed through the iso8601-tzinfo printtime
suboption.
It also makes the new logging format the default for -g output,
hopefully removing the need for custom timestamp parsing in scripts.
The `dns.query.udp` and `dns.query.tcp` methods are [prone to timeouts](https://gitlab.isc.org/isc-projects/bind9/-/jobs/4785053); their `isctest.query` equivalents should be used in system tests instead.
