Changelog for dnsperf-2.14.0.1724332965-150500.1.1.x86_64.rpm :

* Thu Aug 22 2024 Jerry Lundström 2.14.0.1724332965-1- Auto build 2024-08-22T13:22:45+00:00
* Thu Jan 18 2024 Jerry Lundström 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-\" and \"perf-recv-\".
* 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: 81dc36b TSIG context per thread 55011c6 Thread names 8bdd480 thread names 17c680d Set thread names for dnsperf 54e641d Add library function to set thread names fb19440 Dockerfile a80de21 Reword connection statistics 688a4fd Reword connection statistics
* Wed Aug 23 2023 Jerry Lundström 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 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 5fb2282 Add TLS Server Name Indication extension support
* Sun May 21 2023 Jerry Lundström 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 AATTkgillis2000 it was quickly found and fixed.
* The way maximum QPS is handled has been changed by Petr Špaček AATTpspacek (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+
* Commits: 9aca046 OpenSSL 3.0 6d3d6b4 Stats, DoH 316f901 qps_threshold_wait ed52770 WIP: use busy wait only if necessary 32229b6 WIP: import nanosleep benchmark 1842b88 Fix dnsperf -Q to not overshot target value
* Thu Mar 16 2023 Jerry Lundström 2.11.2-1- Release 2.11.2

* Commits: 034e893 Long opt
* Wed Feb 08 2023 Jerry Lundström 2.11.0-1- Release 2.11.0
* A couple of new features this release courtesy of Petr Špaček AATTpspacek (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 AATTfanf2 (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 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 Špaček AATTpspacek (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 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=` 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.
* Commits: cd9df40 Tests 864a968 Queries per connection 7c5d6ab Suppress unexpected 8e9f4a2 Suppress
* Tue Nov 02 2021 Jerry Lundström 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=` 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: 6a452b0 DoH response handling e2828e7 Suppress
* Fri Sep 17 2021 Jerry Lundström 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 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

* Mon May 31 2021 Jerry Lundström 2.6.0-1- Release 2.6.0
* This release adds EDNS options parameter `-E` to `resperf` and a script for generating EDNS Client Subnet options (see `contrib/ecs-gen`).
* Commits: d29d880 ECS opt 877f31e edns option
* Thu Mar 25 2021 Jerry Lundström 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.
* Commits: d9e5663 net test 22f49df network tests 8e5b56e reconnect
* Mon Mar 22 2021 Jerry Lundström 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 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 `: 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 ` 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 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 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 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

* Wed May 06 2020 Jerry Lundström 2.3.3-1- Release 2.3.3
* 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 Menšík (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`.

* Fri Aug 23 2019 Jerry Lundström 2.3.2-1- Release 2.3.2
* This release fixes a buffer overflow when using TSIG and algorithms with digests larger then SHA256, reported by Mukund Sivaraman. Also fix build dependencies for `sqrt()`.
* Commits: e54aa58 Digest bca5d8d sqrt d9eaa5b Package
* Wed Jul 24 2019 Jerry Lundström 2.3.1-1- Release 2.3.1
* 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: 670db9c TCP/TLS receive b8925b2 recvbuf have more
* Wed Jul 17 2019 Jerry Lundström 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

* Mon Jan 28 2019 Jerry Lundström 2.2.1-1- Release 2.2.1
* The commit pulled from a fork that used `inttypes.h`, instead of ISC internal types, missed to remove the old conversion specifier. This was reported and fixed by Vladimír Čunát.
* Commits: 9534ce1 remove visible \"u\" characters after numbers
* Mon Dec 03 2018 Jerry Lundström 2.2.0-1- Release 2.2.0
* First release by DNS-OARC with a rework of the code to use autotools, semantic versioning 2.0 and bugfixes pulled from other\'s forks.
