This also fixes build problems with bind-9.16.13. Detailed changes:
- 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.
- 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
- 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.
- 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.
- 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
Update dnsperf to 2.3.4.

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`.

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.

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

Release Notes
************************
December 15, 2015
In addition to various bug fixes, the following new capabilities
were added in this release:
- The -C option was added to resperf. This option enables the local
server to act as multiple clients. By default, the local server
acts as a single client.
- the -T option was added to dnsperf. This option separates the
number of clients from the number of threads and allows more
clients to be simulated effectively. Note that using this option
impacts CPU and memory, so we recommend limiting the number of
threads.
Problems found with existing distfile for superpi:
distfiles/super_pi-20030927/super_pi.tar.gz
No changes were made to the superpi/distinfo file.
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
distfiles/eagle-lin32-7.4.0.run
DNSPerf, ResPerf, and DHCPerf are free tools developed by Nominum that
make it simple to gather accurate latency and throughput metrics for
Domain Name Service (DNS) and Dynamic Host Configuration Protocol
(DHCP). 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 DNS
test tools (DNSPerf and ResPerf) can be used with new 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.
