We use `dnssec-verify` (from BIND 9.16) to validate large DNSSEC-signed zones. I noticed that on a multi core processor (eg 16 cores) always only one cpu is used. I guess, validation time could be speed up a lot if all available cores would be used.
### Request
Make `dnssec-verify` use all available cores automatically for operations for which this is possible eg. signature verification.
`dnssec-signzone` already automatically detects and uses all available cores and even has an argument switch to specify an specific number (`man dnssec-signzone`). I think something like this would be very useful:
```
-n ncpus
This option specifies the number of threads to use. By default, one thread is started for each detected CPU.

successful IXFRs started being accompanied by a "failed while receiving
responses: no more" log message. This problem was introduced by commit
934d6c6f92ff1761372c532ff50b899ed4264d1d as it removed an early `return`
statement from `lib/dns/xfrin.c:xfrin_recv_done()`.
Here is what is logged for a successful IXFR in BIND 9.17.7+:
24-Feb-2021 22:17:23.280 zone nil/IN: transferred serial 2
24-Feb-2021 22:17:23.280 transfer of 'nil/IN' from 10.53.0.2#5300: failed while receiving responses: no more

These messages are quite confusing because by the time the "failed while
receiving responses: no more" message is logged, the IXFR is already
journalled and applied to the zone.
The simplest solution seems to be to "promote" `ISC_R_NOMORE` to
`ISC_R_SUCCESS` [after going through the ANSWER section of the
transfer][1].

One thing to note about the ADB entries is that the entries for `n1g` through `n7g` have not been used and appear to have been added, but unused, prior to the `dumpdb` (new entries are initialized to a value between 1 and 32 microseconds).
The core of the cycle appears to be:
1. As long as at least one address is found in the ADB for at least one of the names in the NS rrset, no new data is fetched or moved into the ADB
2. As long a `named` is waiting for a response from an address, that ADB entry is preserved
3. `named` sets how long to wait for a response based on the current SRTT
4. An ADB entry can be used even if it is expired
While theoretically any address could be the one fixated on, by virtue point 3 above the ones with the higher SRTT are more likely to be selected than the ones with the lower SRTT.
This is also more likely to happen for a frequently-queried zone with many records with low TTLs, such as the zone of a CDN.
This is not the first time I've seen behavior that I've believed linked to this, but it is the first time a customer has noticed it and it's also the clearest documentation yet for it.
I expect that there are multiple possible solutions to this, with the hard part being choosing the one that we believe will be the easiest to implement and have the lowest chances of unintended consequences.Not plannedhttps://gitlab.isc.org/isc-projects/bind9/-/issues/1831Feature request: Separate NXDOMAIN cache with its own max-ncache-size2024-03-01T10:04:57ZCathy AlmondFeature request: Separate NXDOMAIN cache with its own max-ncache-sizeThis relates to PRSD DDoS attacks, and the effect on participating resolvers when the domain under onslaught is able to keep responding and does not die or rate-limit the resolvers.

The scenario is one in which a very large number of unique names are being queried, the objective being to bypass cached NXDOMAINs in resolvers and to force every name to become a query to the authoritative servers for the domain (or hosting provider) that is being attacked.
Typically, the target servers will either die, or will commence rate-limiting their perceived attackers. In the case of a resolver, this will result in a large number of recursive queries being backlogged while they wait for the server responses that never arrive.
BIND uses fetch-limits to mitigate the non-responding servers scenario.
But in the situation where the servers never die or never rate-limit, the outcome is rather different. Resolvers that can cope with the increase in traffic (which usually isn't actually that much), instead see a rapid increase in memory consumption (and decrease in cache hits!) due to the NXDOMAIN responses that are received and then cached (never to be used again).
One mitigation for resolver operators has been to reduce max-ncache-ttl to silly small values - but the effectiveness of this depends on the structure of the cache nodes and how often opportunistic cache cleaning hits these nodes.
Yes, overmem (LRU-based logic) cache-cleaning will help with this, but for many, it is going to be at the expense of 'positive' cache content, and regular clients will start to suffer with more cache-misses, as well as cache churn increasing as negative and positive cache content keeps being 'swapped'.
Mark suggested keeping negative answers in a separate cache, where they could have their own max-ncache-size and churn all by themselves, without affecting main cache.
This sounds like A Good Idea - but one that we've never get got around to, as part of ongoing DDoS mitigation work.
(Also tagging this as 'Customer' since I can find many a customer ticket where customers have been bitten by this when one specific and well-known DNS hosting company have been under attack, and their servers never falter in sending back NXDOMAIN responses to their 'attackers').Not plannedhttps://gitlab.isc.org/isc-projects/bind9/-/issues/1283[BUGS RT #46650] options/configuration to exempt queries/records from serve-s...2023-11-02T16:43:58ZCathy Almond[BUGS RT #46650] options/configuration to exempt queries/records from serve-stale?From https://bugs.isc.org/Ticket/Display.html?id=46650 and [Support ticket #12071](https://support.isc.org/Ticket/Display.html?id=12071):

While being generally useful in preserving user functionality as much
as possible during certain types of DNS-impacting events, the automatic
serving of stale records complicates the task of properly monitoring
resolvers.
Specifically, it is common to have a name with a very short TTL that is
used only for health checks designed to verify that a resolver is
capable of performing recursion and getting responses. With serve stale
getting an answer to these queries no longer accomplishes that purpose.
In some circumstances, such as when the TTL used for stale records is
larger than the original TTL on the records, it may be possible to infer
that the record is stale by looking at the details of the packet, but
this is not a particularly robust solution.
Further, there are some appliances that perform health checks (among
other features) and they cannot be taught to make decisions based on the
TTL of the received response.
Therefore it seems that it would be desirable for an operator to be able
to configure the resolver to either exempt certain records (by name) from
being served stale, or to exempt certain clients (by ACL) from receiving
stale responses.
Views are not a complete solution to this because there are several types
of resources and data stores (notably the ADB) that are never shared
between views that may affect whether or not the resolver for a view can
perform iteration.Not plannedhttps://gitlab.isc.org/isc-projects/bind9/-/issues/1278Improvements to the performance of view matching2023-11-02T16:43:58ZBrian ConryImprovements to the performance of view matchingA customer has requested that some effort be made to improve the performance of matching an incoming request to a view.

The specific case that they would be delighted to see as a starting point would be if all of the views have only `match-destination` ACLs. In a case like this, the multipl ACLs could be combined into something very much like the existing ACL structure except producing a view selection answer rather than the usual positive-neutral-negative answer.Not plannedhttps://gitlab.isc.org/isc-projects/bind9/-/issues/1276[ISC-support #15512] improve interoperability between catalog zones and respo...2021-10-04T19:58:25ZBrian Conry[ISC-support #15512] improve interoperability between catalog zones and response-policy configurationA customer has requested two things related to catalog zones and response-policy statements.

### Steps to reproduce
A VM with 2 CPUs and 32G Ram. Configure Bind to load the "net" zone (freely available via https://czds.icann.org/home):
```
zone "net" {
type master;
file "/etc/bind/zones/net";
allow-transfer { 1.2.3.0/21; };
notify explicit;
also-notify { 1.2.3.139; };
};
```
Then, start Bind and wait until the zone is loaded and DNS queries are served.
In a second shell starting querying the zone, for example: `while true; do date; dig @127.0.0.1 SOA net |egrep 'a.gtld-servers.net.|Query time|timed out';echo ""; sleep 1; done`
Then, increase the zone's serial - I use "hexedit" as normal editors try load the whole textfile.
Then call `rndc reload net`. In my setup, loading the zone takes around 3 minutes. As the zone is already in the file buffers, the zone loading is CPU bound. One of my CPUs is at 100%, the other CPU is idle. When the zone was loaded, Bind starts with validity checks ("zone net/IN: loaded; checking validity").
Once the validity checks begin, Bind becomes unresponsive and dig experiences timeouts. during the validity checks, Bind also consumes 1 CPU with 100%, the other CPU is idle. RAM is not an issue, after initial loading Bind uses 4.3G RAM, after reload 8.6G RAM.
Please see attached log files from Bind and the output of my dig command. You can relate the timestamps.
I have seen this issue also with Bind slaves with other large zones and large IXFRs. I initially thought this is a disk IO problem when dumping zones/journals to disk. But this time I can reproduce it with a "master" setup where there are now disk writes - only disk-reads from data which is in the buffers. Hence I do not believe this is a disk-IO problem.
I have seens this behavior also with Bind 9.11.3+dfsg-1ubuntu1.8 and older Bind versions.
I have reported this before on the users mailing list, but never gained attraction:

### What is the current *bug* behavior?

### What is the expected *correct* behavior?
Bind should answer queries without drops during the zone reload.
