The nslookup system test checks the count of resolved addresses in
the CNAME tests using a 'grep' match on the hostname, and ignoring
lines containing the 'canonical name' string. In order to protect
the check from intermittent failures like the 'address in use' warning
message, which then automatically resolves after a retry, edit the
'grep' matching string to also ignore the comments (as the mentioned
warning message is a comment which contains the hostname).

In some cases (there is evidence only when XoT was used) `named` failed
to try the next primary server in the list when the previous one was
marked as unreachable. This has been fixed.

Add test cases which check that when a XoT primary server is
unreachable or is already marked as unreachble then the next
primary server in the list is used.
(cherry picked from commit 12225d125b)
Previously a ISC_R_CANCELED result code switch-case has been added to
the zone.c:zone_xfrdone() function, which did two things:
1. Schedule a new zone transfer if there's a scheduled force reload of
the zone.
2. Reset the primaries list.
This proved to be not a well-thought change and causes problems,
because the ISC_R_CANCELED code is used not only when the whole transfer
is canceled, but also when, for example, a particular primary server is
unreachable, and named still needs to continue the transfer process by
trying the next server, which it now no longer does in some cases. To
solve this issue, three changes are made:
1. Make sure dns_zone_refresh() runs on the zone's loop, so that the
sequential calls of dns_zone_stopxfr() and dns_zone_forcexfr()
functions (like done in 'rndc retransfer -force') run in intended
order and don't race with each other.
2. Since starting the new transfer is now guaranteed to run after the
previous transfer is shut down (see the previous change), remove the
special handling of the ISC_R_CANCELED case, and let the default
handler to handle it like before. This will bring back the ability to
try the next primary if the current one was interrupted with a
ISC_R_CANCELED result code.
3. Change the xfrin.c:xfrin_shutdown() function to pass the
ISC_R_SHUTTINGDOWN result code instead of ISC_R_CANCELED, as it makes
more sense.

The new log message is emitted when adding or updating an RRset
fails due to exceeding the max-records-per-type limit. The log includes
the owner name and type, corresponding zone name, and the limit value.
It will be emitted on loading a zone file, inbound zone transfer
(both AXFR and IXFR), handling a DDNS update, or updating a cache DB.
It's especially helpful in the case of zone transfer, since the
secondary side doesn't have direct access to the offending zone data.
It could also be used for max-types-per-name, but this change
doesn't implement it yet as it's much less likely to happen
in practice.

DNS_LOGMODULE_RBTDB was simply inappropriate, and this

(cherry picked from commit 99b4f01b33)
`dig` fails to parse a valid (as far as I can tell, and accepted by `kdig` and `Wireshark`) `SVCB` record with a `dohpath` URI template containing a `{&dns}`, like `dohpath=/some/path?key=value{&dns}"`. If the URI template contains a `{?dns}` instead `dig` is happy, but my understanding of rfc9461 and section 1.2. "Levels and Expression Types" of rfc6570 is that `{&dns}` is valid.
See for example section 1.2. "Levels and Expression Types" of rfc6570.
Note that Peter van Dijk suggested that `{dns}` and `{dns,someothervar}` might be valid forms as well, so my patch might be too restrictive, although it's anyone's guess how DoH clients would handle complex templates.

The 'dns' variable in dohpath can be in various forms ({?dns},
{dns}, {&dns} etc.). To check for a valid dohpath it ends up
being simpler to just parse the URI template rather than looking
for all the various forms if substring.

There is a data race between the statistics channel, which uses
`dns_zone_getxfr()` to get a reference to `zone->xfr`, and the creation
of `zone->xfr`, because the latter happens outside of a zone lock.
Split the `dns_xfrin_create()` function into two parts to separate the
zone transfer starting part from the zone transfer object creation part.
This allows us to attach the new object to a local variable first, then
attach it to `zone->xfr` under a lock, and only then start the transfer.

When canceling the ADB find, the lock on the find gets released for

the brief period that the ADB find is unlocked, it can get canceled by
other means removing it from the adbname list which in turn causes
assertion failure due to a double removal from the adbname list.

Recheck if the find->adbname is still valid after acquiring the lock
again and if not just skip the double removal. Additionally, attach to
the adbname as in the worst case, the adbname might also cease to exist
if the scheduler would block this particular thread for a longer period
of time invalidating the lock we are going to acquire and release.
