%description
dnsperf and resperf are free tools developed by Nominum/Akamai (2006-2018)
and DNS-OARC (since 2019) that make it simple to gather accurate latency and
throughput metrics for Domain Name Service (DNS). These tools are easy-to-use
and simulate typical Internet, so network operators can benchmark their naming
and addressing infrastructure and plan for upgrades. The latest version of
the dnsperf and resperf can be used with test files that include IPv6
queries.
dnsperf "self-paces" the DNS query load to simulate network conditions.
New features in dnsperf improve the precision of latency measurements and
allow for per packet per-query latency reporting is possible. dnsperf is
now multithreaded, multiple dnsperf clients can be supported in multicore
systems (each client requires two cores). The output of dnsperf has also
been improved so it is more concise and useful. Latency data can be used to
make detailed graphs, so it is simple for network operators to take advantage
of the data.

* Thu Jan 18 2024 Jerry Lundström <lundstrom.jerry@gmail.com> 2.14.0-1
- Release 2.14.0
* This release rewords connection statistics, adds names to threads and
fixes a bug with using TSIG in more than one thread.
* In "Connection Statistics", reconnections has been renamed to
connection attempts and now includes both the initial connection
attempt and following reconnections.
* If supported, threads will now be named after what they do, such as
"perf-send-<num>" and "perf-recv-<num>".
* The TSIG context was shared between all threads and would case a crash
if more than one sending thread was used. This has been fixed and TSIG
contexts are now per thread.
* Commits:

* Wed Aug 23 2023 Jerry Lundström <lundstrom.jerry@gmail.com> 2.13.1-1
- Release 2.13.1
* This release fixes a few issues with in-progress queries and the TCP
transport module.
* When using stateful connections, such as TCP, if the full query couldn't
be sent in one go then the query and connection could get stuck as
"in-progress".
This could easily happen if you limited the in-flight queries to 1 and
sent very large DNS messages using the stream binary format.
Additional socket ready checks has been added to flush in-progress
queries as quickly as possible.
* The TCP module's handling of errors when continuing in-progress queries
has been fixed. Previously it would interpret EAGAIN as an unrecoverable
error and trigger a reconnect, dropping the quer-y/ies in-progress for
that connection.
* Other changes:
- Fix input data buffer to allow for maximum binary blob wire format, 2 byte size + max DNS message
- Mention PowerTools repository for building on CentOS etc

* Thu Jun 15 2023 Jerry Lundström <lundstrom.jerry@gmail.com> 2.13.0-1
- Release 2.13.0
* This release adds a new option `-O tls-sni=...` to set the Server Name
Indication when using TLS transport, currently for DNS-over-TLS and
DNS-over-HTTPS.
* Commits:
dbe84f6 TLS SNI

* Sun May 21 2023 Jerry Lundström <lundstrom.jerry@gmail.com> 2.12.0-1
- Release 2.12.0
* This release fixes a segfault when doing DNS-over-HTTPS and changes the
way maximum queries per second are handled.
* The DNS-over-HTTPS module handled reconnecting incorrectly and destroyed
the nghttp2 context during callbacks. Thanks to the help from
@kgillis2000 it was quickly found and fixed.
* The way maximum QPS is handled has been changed by Petr Å paÄek @pspacek
(ISC). The new way solves an over-shoot problem that happened due to
max QPS being counted for the whole runtime and based on completed
queries, not just sent.
* A new option `qps_threshold_wait` has also been added. This controls
the threshold for using `nanosleep()` between sending packet and the
default is measured on start-up. If the time between packets, based on
max QPS `-Q`, is smaller then no sleep will be performed. This improves
performance when doing high max QPS limiting.
* Other changes:
- `dnsperf`: Statistics output
- Fixed missing connection statistics if only reconnections happened
- Flush output to allow pipe/grep processing
- Add percentage on reconnections based on total connections
- Support OpenSSL 3.0+

* Wed Feb 08 2023 Jerry Lundström <lundstrom.jerry@gmail.com> 2.11.0-1
- Release 2.11.0
* A couple of new features this release courtesy of Petr Å paÄek
@pspacek (ISC) and a bunch of bugfixes.
* First off `dnsperf` can now do verbose statistics during each interval
when using `-S`, see long option `verbose-interval-stats`.
* Next is a new latency histogram output using data structures (hg64)
created by Tony Finch @fanf2 (ISC), see long option
`latency-histogram`. These will also be shown during `-S` when used
together with `verbose-interval-stats`.
* Lastly a small change to boolean long options, they no longer require
a value (`=yes`) to be enabled.
* Bugfixes:
- Make sure the number of outstanding queries don't go negative,
happens if queries are timed out before being sent
- Fixed #208:
- `recv_one()`: Fix handling errno, only store EAGAIN if no other
error has been received
- `do_recv()`: Don't break on error as it will count it as a received
message
- Treat `EBADF` as `EAGAIN` for stateful connections, receive thread
might read from a closed socket if send thread is reconnecting
- `dnsperf`: warn if -c, -T, -q, -Q values are auto-adjusted
- Fixed #222: don't process unexpected message if the message is
suppressed

* Fri Nov 11 2022 Jerry Lundström <lundstrom.jerry@gmail.com> 2.10.0-1
- Release 2.10.0
* This release adds a binary datafile (DNS wire) format to `dnsperf`
thanks to a contribution from Petr Å paÄek @pspacek (ISC).
* The new binary format greatly improves performance in some cases, for
Petr's case it was testing dynamic updates. Switching to this
pre-compiled DNS wire format increased QPS from 4k to 600k, an increase
of 150 times throughput from `dnsperf`!
* See man-page for `-B` for more information and examples how to use.

* Wed Dec 08 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.9.0-1
- Release 2.9.0
* This release brings a new message suppression option and a way to control
how many queries are sent over a connection.
* You can now suppress the message about receiving unexpected DNS message
IDs by using `-O suppress=unexpected`.
* With `-O num-queries-per-conn=<num>` you can now limit the number of
queries sent over a connection before triggering a re-connection, see
the `dnsperf(3)` man-page for more information how this works.

* Tue Nov 02 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.8.0-1
- Release 2.8.0
* This release fixes response handling for DNS-over-HTTPS when multiple
responses are received within the same receive cycle, and adds a new
option to suppress some of the normal and verbose output.
* The network model within dnsperf and resperf can not process more then
one response at a time from a protocol module, so a buffer has been added
to the DNS-over-HTTPS module to handle this situation (this already exists
in all other modules).
* The new option `-O suppress=<message,...>` can selectively suppress parts
of the normal and verbose output. Some of these messages might be
excessively displayed due to the network model and depending on what
protocol you use which makes usage harder then necessary. For example
during TCP connection stage, if you end-point is slow to establish
connection you will get a lot of output saying that the socket isn't ready
yet.
* Commits:

* Fri Sep 17 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.7.1-1
- Release 2.7.1
* This release fixes issues with constructing wire-format DNS when the
domain names includes escaped characters such as `\123` or `\.`.
* Other changes:
- Bump Debian package compat level to 10
* Commits:
4873f02 DNS encoding
c4eccc0 debhelper
* Mon Aug 09 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.7.0-1
- Release 2.7.0
* This release adds DNS-over-HTTPS support!
* DNS-over-HTTPS can be used by specifying transport mode `doh` and you
should also look at the dnsperf(1) man-page (or `-H`) for the extended
options `doh-uri` and `doh-method`, which controls aspects of DoH/HTTP/2
that you might want to set.
* Other fixes:
- Add check when constructing DNS packet so that total length of labels
does not exceed 255 bytes
- Fix connection/reconnection state handling for DoT transport
- Fix event handling by initializing them directly when opening the
sockets, otherwise events could have been missed which would give
incorrect statistics

* Thu Mar 25 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.5.2-1
- Release 2.5.2
* This release tweaks the reconnect code for TCP and DoT.
* For TCP, atomic operations are used to signal the need to reconnect
from the receiving thread to the sending, as the sending is the one in
charge of reconnecting.
This speeds up detection of connection lost which reduces the amount of
lost queries on a disconnect.
* This change does not affect DoT as much, as the SSL context shared
between the threads are protected by a mutex.
But a bug was found in `sendto()` for DoT that could drop a query if
the socket was busy sending.
* The connect and reconnect socket events has been split into connecting,
connected and reconnecting, reconnected. This is to report more correct
reconnect events when it comes to DoT, because the connection can be
lost while negotiating TLS.
* Lastly, additional tests has been added for the network code.

* Mon Mar 22 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.5.1-1
- Release 2.5.1
* This release re-adds support for TYPEnnn and ANY in the datafile, this
was missed during the removal of the dependency on BINDs development
libraries in v2.4.0.
* Also note that with v2.5.0, this software now depends on Concurrency
Kit (ck) for atomic operations.
* Commits:
924e6ea ANY
0a444c0 TYPEnnn
* Fri Mar 12 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.5.0-1
- Release 2.5.0
* This release adds re-connection support for TCP and DoT protocol,
new options to `resperf` and fixes a few bugs.
* `dnsperf` and `resperf` will now try to re-connect when they lose a TCP
or DoT connection, and with that comes a few new statistics metrics.
For `dnsperf`, if a connection oriented protocol is used, it will now
show the total number of re-connections made and the connection latency.
For `resperf` it also shows the total number of re-connections made and
the gnuplot data now contains the total number of connections made and
the connection latency for each interval.
Beside re-connection support, improvements have been made when it comes
to tracking socket readiness while connections are established which
should generate less warnings about "socket not ready".
* New `resperf` options:
- `-R`: Reopen the datafile if it runs out of data before the testing
is completed. This allows for long running tests on very small and
simple query datafile.
- `-F <fall_behind>`: Sets the maximum number of queries that can fall
behind being sent. `resperf` will stop when this many queries should
have been sent and it can be relative easy to hit if `-m <max_qps>`
is set too high.
The default is 1000 and setting it to zero (0) disables the check.
* Bugfixes:
- Fixed port handling for host/network format when setting client side
port with `-x`
- Fix support for quoted characters, `\000` and `\.`, in domain names,
this was lost when removing BIND's internal development libraries
- Fix issue in `dnsperf`, it would loop forever if no connection could
be established
- Fix potential buffer overrun in `resperf` when using response id
for `queries[]`
- DoT: Fix bug when sending from buffer
* Other changes:
- Always use `IPV6_V6ONLY` socket option for IPv6
- Add man-page on `-W` option added in v2.4.0
- Reformat man-pages
- `resperf`:
- Try and process more request each run to hopefully not hit max
outstanding so easy when high QPS
- Add default value to `-C` so it shows in help

* Tue Feb 23 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.4.2-1
- Release 2.4.2
* This release fixes a few issues with reading of the datafile which
could lead to "ran out of data" errors.
* The problem was that reading from the datafile was done before finding
a socket to send it on, or socket readyness, and that lead to progressing
the queries without really doing anything.
Another issues that's been fixed was that if the read lines perfectly
aligned with the buffer, it would be treated like EOF and caused an exit.
* Commits:
9937287 resperf TLS
6736956 datafile
55faec6 ran out of data
* Tue Feb 09 2021 Jerry Lundström <lundstrom.jerry@gmail.com> 2.4.1-1
- Release 2.4.1
* This release fixes an issue with the socket readiness function that
could cause a buffer overflow (`-T 10 -c 2000`) due to `select()` being
limited to check 1023 sockets. `poll()` is now used which has no limit.
* There has also been a few fixes to the contrib script `queryparse` that
has to do with python v2 and v3 compatibility and better exception
handling.
* Commits:
24e5bee poll
7dceca7 Handle only common exceptions
5603294 Fix error on python3
48fa517 TSIG
* Wed Dec 09 2020 Jerry Lundström <lundstrom.jerry@gmail.com> 2.4.0-1
- Release 2.4.0
* This release removes the dependency on BIND's internal development
libraries! This make building and packaging a lot easier and less
troublesome in the future.
* This software now depends only on OpenSSL (for TSIG feature) with an
optional depend on LDNS (for dynamic updates feature).
* New option:
- Transport mode option `-m`/`-M` now recognizes `dot` alongside `tls`
for encrypted DNS
- Added `-W` for outputting warnings and errors to stdout
* Other changes / bugfixes:
- Fix potential memory leak of query descriptions when using verbose
- Only use TLS v1.2 and above for DoT/TLS
- Add a lot of tests
- Add coverage testing

* This release changes the behavior of `dnsperf` and `resperf` when it
comes to TCP and TLS connections, and updates package building using
COPR (thanks to patch from Petr MenÅ¡Ãk (Red Hat)).
* Connection reset or close are now treated as "try again" so that the
run is finished and not aborted. As SIGPIPE might be received on usage
of closed connections it's now blocked in `dnsperf` and handled as
a fatal action in `resperf`.

* After a report and additional confirming results the use of `poll()` in
the network receive code for TCP and TLS has been removed. This `poll()`
initially gave better results while testing in a docker container on
it's loopback interface but when on physical networks it reduced
performance to 1/12th, so it had to go.
* Thanks to Brian Wellington (Akamai/Nominum) for the initial report and
testing, and to Jan Hák (CZ.NIC) for testing and confirming the results.
* Bugfix:
- Fix check for having more DNS messages in the receive buffer for TCP
and TLS
* Commits:

* Wed Jul 17 2019 Jerry Lundström <lundstrom.jerry@gmail.com> 2.3.0-1
- Release 2.3.0
* This release adds support for DNS over TCP and TLS which can be selected
by using the mode option for `dnsperf` and `resperf`. The default server
port used is now determined by the transport mode, udp/tcp port 53 and
tls port 853.
* Note that the mode option is different between the program because it was
already taken for `resperf`.
* `dnsperf` changes:
- Add `-m` for setting transport mode, `udp` (default), `tcp` or `tls`
- Add verbose messages about network readiness and congestion
* `resperf` changes:
- Add `-M` for setting transport mode, `udp` (default), `tcp` or `tls`
- Add `-v` for verbose mode to report about network readiness and
congestion
