|
|
|
* Notable user-visible changes
|
|
|
|
* A new --extra-data option can be used to fill in a user-defined
|
|
string field that appears in JSON output. (#600 / #729)
|
|
|
|
* A new --repeating-payload option makes iperf3 use a payload pattern
|
|
similar to that used by iperf2, which could help in recreating
|
|
results that might be affected by payload entropy (for example,
|
|
compression). (#726)
|
|
|
|
* -B now works properly with SCTP tests. (#678 / #715)
|
|
|
|
* A compile fix for Solaris 10 was added. (#711)
|
|
|
|
* Some minor bug fixes for JSON output. In particular, warnings for
|
|
debug and/or verbose modes with --json output (#737) and a fix for
|
|
JSON output on CentOS 6 (#727 / #744).
|
|
|
|
* software.es.net and downloads.es.net now support HTTPS, so URLs in
|
|
documentation that refer to those two hosts now use https://
|
|
instead of http:// URLs. (#759)
|
|
|
|
* Notable developer-visible changes
|
|
|
|
* Functions related to authenticated iperf3 connections have been
|
|
exposed via libiperf. (#712 / #713)
|
|
|
|
* The ToS byte is now exposed in the libiperf API. (#719)
|
|
|
|
== iperf 3.5 2018-03-02 ==
|
|
|
|
* Notable user-visible changes
|
|
|
|
* iperf3 no longer counts data received after the end of a test in
|
|
the bytecounts. This fixes a bug that could, under some
|
|
conditions, artificially inflate the transfer size and measured
|
|
bitrate. This bug was most noticeable on reverse direction
|
|
transfers on short tests over high-latency or buffer-bloated
|
|
paths. Many thanks to @FuzzyStatic for providing access to a test
|
|
environment for diagnosing this issue (#692).
|
|
|
|
== iperf 3.4 2018-02-14 ==
|
|
|
|
* Notable user-visible changes
|
|
|
|
* The -A (set processor affinity) command-line flag is now supported
|
|
on Windows (#665).
|
|
|
|
* iperf3 now builds on systems lacking a daemon(3) library call
|
|
(#369).
|
|
|
|
* A bug in time skew checking under authentication was fixed (#674).
|
|
|
|
* IPv6 flow labels now work correctly with multiple parallel streams
|
|
(#694).
|
|
|
|
* The client no longer closes its control connection before sending
|
|
end-of-test statistics to the server (#677). This fixes a
|
|
regression introduced in iperf-3.2.
|
|
|
|
* Sending output to stdout now makes errors go to stderr, as per
|
|
UNIX convention (#695).
|
|
|
|
* A server side crash in verbose output with a client running
|
|
multiple parallel connections has been fixed (#686).
|
|
|
|
* The --cport option can now be specified without the --bind option.
|
|
Using the --cport option on Linux can eliminate a problem with
|
|
ephemeral port number allocation that can make multi-stream iperf3
|
|
tests perform very poorly on LAGG links. Also, the --cport option
|
|
now works on SCTP tests (#697).
|
|
|
|
* Notable developer-visible changes
|
|
|
|
* iperf3 now builds on (some) macOS systems older than 10.7 (#607).
|
|
|
|
* Some unused code and header inclusions were eliminated (#667,
|
|
#668). Also some code was cleaned up to eliminate (or at least
|
|
reduce) compiler warnings (#664, #671).
|
|
|
|
== iperf 3.3 2017-10-31 ==
|
|
|
|
* Notable user-visible changes
|
|
|
|
* iperf3 can now be built --without-openssl on systems where OpenSSL
|
|
is present (#624, #633).
|
|
|
|
* A bug with printing very large numbers has been fixed (#642).
|
|
|
|
* A bug where the server would, under certain circumstances, halt a
|
|
test after exactly fifteen seconds has been fixed (#645).
|
|
|
|
* The --tos parameter is no longer "sticky" between tests when doing
|
|
--reverse tests (#639).
|
|
|
|
* The authentication token on the server is properly reset between
|
|
tests (#650).
|
|
|
|
* A bug that could cause iperf3 to overwrite the PID file of an
|
|
already-existing iperf3 process has been fixed (#623).
|
|
|
|
* iperf3 will now ignore nonsensical TCP MSS values (from the TCP
|
|
control connection) when trying to determine a reasonable block
|
|
size for UDP tests. This condition primarily affected users on
|
|
Windows, but potentially improves robustness for all
|
|
platforms. (#659)
|
|
|
|
* Notable developer-visible changes
|
|
|
|
== iperf 3.2 2017-06-26 ==
|
|
|
|
* User-visible changes
|
|
|
|
* Authentication via a username/password mechanism, coupled with a
|
|
public-key pair, is now an optional way of limiting access to an
|
|
iperf3 server (#517).
|
|
|
|
* Ending statistics are less ambiguous for UDP and also now use
|
|
correct test durations for all protocols (#560, #238). Many fixes
|
|
have been made in statistics printing code, generally for
|
|
human-readable output (#562, #575, #252, #443, #236).
|
|
|
|
* Several problems with the -F/--file options have been fixed.
|
|
Documentation has been improved to note some ways in which this
|
|
feature might not behave as expected (#588).
|
|
|
|
* iperf3 now uses the correct "bitrate" phraseology rather than
|
|
"bandwidth" when describing measurement results. The --bandwidth
|
|
option has been renamed --bitrate, although --bandwidth is still
|
|
accepted for backwards compatibility (#583).
|
|
|
|
* Application-level bandwidth pacing (--bitrate option) is now
|
|
checked every millisecond by default, instead of of every tenth of
|
|
a second, to provide smoother traffic behavior when using
|
|
application pacing (#460). The pacing can be tuned via the use of
|
|
the --pacing-timer option (#563).
|
|
|
|
* A new --dscp option allows specifying the DSCP value to be used
|
|
for outgoing packets (#508). The TOS byte value is now printed in
|
|
the JSON output (#226).
|
|
|
|
* Congestion window data on FreeBSD is now computed correctly (#465,
|
|
#475, #338).
|
|
|
|
* The T/t suffixes for terabytes/terabits are now accepted for
|
|
quantities where suffixes are supported, such as --bandwidth
|
|
(#402).
|
|
|
|
* Sanity checks for UDP send sizes have been added (#390), and
|
|
existing checks on the --window option have been improved (#557).
|
|
|
|
* The TCP rttvar value is now available in the JSON output (#534), as are
|
|
the socket buffer sizes (#558).
|
|
|
|
* Error handling and documentation have been improved for the
|
|
-f/--format options (#568).
|
|
|
|
* A new --connect-timeout option on the client allows specifying a
|
|
length of time that the client will attempt to connect to the
|
|
server, in milliseconds (#216).
|
|
|
|
* The hostname and current timestamp are no longer used in the
|
|
cookie used to associate the client and server. Instead, random
|
|
data is used. Note that iperf3 now requires the /dev/urandom
|
|
device (#582).
|
|
|
|
* Prior versions of iperf3 doing UDP tests used to overcount packet
|
|
losses in the presence of packet reordering. This has been
|
|
(partially) fixed by try to not count the sequence number gaps
|
|
resulting from out-of-order packets as actual losses (#457).
|
|
|
|
* iperf3 no longer prints results from very small intervals (10% of
|
|
the statistics reporting interval) at the end of the test run if
|
|
they contain no data. This can happen due to timing difference or
|
|
network queueing on the path between the client and server. This
|
|
is primarily a cosmetic change to prevent these fairly meaningless
|
|
intervals from showing up in the output (#278).
|
|
|
|
* Compatiblity note: Users running iperf3 3.2 or newer from the
|
|
bwctl utility will need to obtain version 1.6.3 or newer of bwctl.
|
|
Note that bwctl, a component of the perfSONAR toolkit, has been
|
|
deprecated in favor of pScheduler since the release of perfSONAR
|
|
4.0.
|
|
|
|
* Developer-visible changes
|
|
|
|
* Various warnings and build fixes (#551, #564, #518, #597).
|
|
|
|
* Some improvements have been made for increased compatibility on
|
|
IRIX (#368) and with C++ (#587).
|
|
|
|
* cJSON has been updated to 1.5.2 (#573), bringing in a number of
|
|
bugfixes.
|
|
|
|
* Some dead code has been removed.

|
== iperf 3.1.7 2017-03-06 ==
|
|
|
|
iperf 3.1.7 is functionally identical to iperf 3.1.6. Its only
|
|
changes consist of updated documentation files and text in the RPM
|
|
spec file.
|
|
|
|
== iperf 3.1.6 2017-02-02 ==
|
|
|
|
The release notes for iperf 3.1.6 describe changes, including bug
|
|
fixes and new functionality, made since iperf 3.1.5.
|
|
|
|
* User-visible changes
|
|
|
|
* Specifying --fq-rate or --no-fq-socket-pacing on a system where
|
|
these options are not supported now generate an error instead of a
|
|
warning. This change makes diagnosing issues related to pacing
|
|
more apparent.
|
|
|
|
* Fixed a bug where two recently-added diagnostic messages spammed
|
|
the JSON output on UDP tests.
|
|
|
|
== iperf 3.1.5 2017-01-12 ==
|
|
|
|
The release notes for iperf 3.1.5 describe changes, including bug
|
|
fixes and new functionality, made since iperf 3.1.4.
|
|
|
|
Compatibility note: Fair-queueing is now specified differently in
|
|
iperf 3.1.5 than in prior versions (which include 3.1.3 and 3.1.4).
|
|
|
|
Compatibility note: UDP tests may yield different results from all
|
|
prior versions of iperf3 (through 3.1.4) due to the new default UDP
|
|
sending size.
|
|
|
|
* User-visible changes
|
|
|
|
* The fair-queueing per-socket based pacing available on recent
|
|
Linux systems has been reimplemented with a different user
|
|
interface (#325, #467, #488). The --bandwidth command-line flag
|
|
now controls only the application-level pacing, as was the case in
|
|
iperf 3.1.2 and all earlier versions. Fair-queueing per-socket
|
|
based pacing is now controlled via a new --fq-rate command-line
|
|
flag. Note that TCP and UDP tests may use --bandwidth, --fq-rate,
|
|
both flags, or neither flag. SCTP tests currently support
|
|
--bandwidth only. The --no-fq-socket-pacing flag, which was
|
|
introduced in iperf 3.1.3, has now been deprecated, and is
|
|
equivalent to --fq-rate=0. iperf3 now reacts more gracefully if
|
|
--no-fq-socket-pacing or --fq-rate are specified on platforms that
|
|
don't support these options.
|
|
|
|
For UDP tests, note that the default --bandwidth is 1 Mbps. Using
|
|
the fair-queueing-based pacing will probably require explicitly
|
|
setting both --bandwidth and --fq-rate, preferably to the same
|
|
value. (While setting different values for --bandwidth and
|
|
--fq-rate can certainly be done, the results can range from
|
|
entertaining to perplexing.)
|
|
|
|
* iperf3 now chooses a more sane default UDP send size (#496, #498).
|
|
The former default (8KB) caused IP packet fragmentation on paths
|
|
having smaller MTUs (including any Ethernet network not configured
|
|
for jumbo frames). This could have effects ranging from increased
|
|
burstiness, to packet loss, to complete failure of the test.
|
|
iperf3 now attempts to use the MSS of the control connection to
|
|
determine a default UDP send size if no sending length was
|
|
explicitly specified with --length.
|
|
|
|
* Several checks are now made when setting the socket buffer sizes
|
|
with the -w option, to verify that the settings have been applied
|
|
correctly. The results of these checks can been seen when the
|
|
--debug flag is specified. (#356)
|
|
|
|
* A --forceflush flag has been added to flush the output stream
|
|
after every statistics reporting interval.
|
|
|
|
* Developer-visible changes
|
|
|
|
* A systemd service file has been added (#340, #430).
|
|
|
|
== iperf 3.1.4 2016-10-31 ==
|
|
|
|
The release notes for iperf 3.1.4 describe changes, including bug
|
|
fixes and new functionality, made since iperf 3.1.3.
|
|
|
|
* User-visible changes
|
|
|
|
* On systems that support setting the congestion control algorithm,
|
|
iperf3 now keeps track of the congestion control algorithm and
|
|
print it in the JSON output in the members sender_tcp_congestion
|
|
and receiver_tcp_congestion (issue #461). A few bugs (probably
|
|
not user-visible) with setting the congestion control algorithm
|
|
were also fixed.
|
|
|
|
* Developer-visible changes
|
|
|
|
* Fixed a buffer overflow in the cJSON library (issue #466). It is
|
|
not believed that this bug created any security vulnerabilities in
|
|
the context of iperf3.
|
|
|
|
* Travis CI builds are now enabled on this codeline (pull request #424).
|
|
|
|
* Various bug fixes (issue #459, pull request #429, issue #388).
|
|
|
|
== iperf 3.1.3 2016-06-08 ==
|
|
|
|
The release notes for iperf 3.1.3 describe changes, including bug
|
|
fixes and new functionality, made since iperf 3.1.2.
|
|
|
|
* Security
|
|
|
|
* Fixed a buffer overflow / heap corruption issue that could occur
|
|
if a malformed JSON string was passed on the control channel. In
|
|
theory, this vulnerability could be leveraged to create a heap
|
|
exploit. This issue, present in the cJSON library, was already
|
|
fixed upstream, so was addressed in iperf3 by importing a newer
|
|
version of cJSON (plus local ESnet modifications). Discovered and
|
|
reported by Dave McDaniel, Cisco Talos. Cross-references:
|
|
TALOS-CAN-0164, ESNET-SECADV-2016-0001, CVE-2016-4303.
|
|
|
|
* User-visible changes
|
|
|
|
* On supported platforms (recent Linux), iperf3 can use
|
|
fair-queueing-based per-socket pacing instead of its own
|
|
application-level pacing for the --bandwidth option.
|
|
Application-level pacing can be forced with the
|
|
-no-fq-socket-pacing flag.
|
|
|
|
* A bug that could show negative loss counters with --udp and --omit
|
|
has been fixed (issue #412, pull request #414).
|
|
|
|
* Error handling has been made slightly more robust. Also, the
|
|
iperf3 server will no longer exit after five consecutive errors,
|
|
but will only exit for certain types of errors that prevent it
|
|
from participating in any tests at all.
|
|
|
|
* Developer-visible changes
|
|
|
|
* Fixed the build on FreeBSD 11-CURRENT (issue #413).
|
|
|
|
* Fixed various coding errors (issue #423, issue #425).
|
|
|
|
== iperf 3.1.2 2016-02-01 ==
|
|
|
|
The release notes for iperf 3.1.2 describe changes, including bug
|
|
fixes and new functionality, made since iperf 3.1.1.
|
|
|
|
* User-visible changes
|
|
|
|
* Fixed a bug that caused nan values to be emitted (incorrectly)
|
|
into JSON, particularly at the end of UDP tests (issue #278).
|
|
|
|
* Fixed a bug that caused the wrong value to be printed for
|
|
out-of-order UDP packets (issue #329).
|
|
|
|
* Added a contrib/ directory containing a few submitted graphing
|
|
scripts.
|
|
|
|
* Developer-visible changes
|
|
|
|
== iperf 3.1.1 2015-11-19 ==
|
|
|
|
The release notes for iperf 3.1.1 describe changes and new
|
|
functionality in iperf 3.1.1, but not present in 3.1.
|
|
|
|
* User-visible changes
|
|
|
|
* Some markup fixes have been made in the manpages for Debian
|
|
compatibility (issue #291).
|
|
|
|
* A bug where the -T title option was not being output correctly
|
|
in JSON output has been fixed (issue #292).
|
|
|
|
* Argument handling for some command-line options has been improved
|
|
(issue #316).
|
|
|
|
* Developer-visible changes
|
|
|
|
* A regression with C++ compatibility in one of the iperf header
|
|
files has been fixed (issue #323).
|
|
|
|
== iperf 3.1 2015-10-16 ==
|
|
|
|
The release notes for iperf 3.1 describe changes and new
|
|
functionality in iperf 3.1, but not present in 3.0.11 or any earlier
|
|
3.0.x release.
|
|
|
|
* Selected user-visible changes
|
|
|
|
* SCTP support has been added (with the --sctp flag), on Linux,
|
|
FreeBSD, and Solaris (issue #131).
|
|
|
|
* Setting CPU affinity now works on FreeBSD.
|
|
|
|
* Selection of TCP congestion now works on FreeBSD, and is now
|
|
called --congestion (the old --linux-congestion option works
|
|
but is now deprecated).
|
|
|
|
* A new -I option for the server causes it to write a PID file,
|
|
mostly useful for daemon mode (issue #120).
|
|
|
|
* A --logfile argument can now force all output to go to a file,
|
|
rather than to a file. This is especially useful when running an
|
|
iperf3 server in daemon mode (issue #119).
|
|
|
|
* Various compatibility fixes for Android (issue #184, issue #185),
|
|
iOS (issue #288), NetBSD (issue #248), Solaris (issue #175, issue
|
|
#178, issue #180, issue #211), vxWorks (issue #268).
|
|
|
|
* A --udp-counters-64bit flag has been added to support very
|
|
long-running UDP tests, which could cause a counter to overflow
|
|
(issue #191).
|
|
|
|
* A --cport option to specify the client-side port has been added
|
|
(issue #207, issue #209, issue #239).
|
|
|
|
* Some calculation errors with the -O feature have been fixed (issue
|
|
#236).
|
|
|
|
* A potential crash in the iperf3 server has been fixed (issue #257,
|
|
issue #258).
|
|
|
|
* Many miscellaneous bug fixes.
|
|
|
|
* Selected developer-visible changes
|
|
|
|
* Consumers of libiperf can now get the JSON output for a
|
|
just-completed test (issue #147).
|
|
|
|
* Detection of various optional features has been improved to check
|
|
for the presence or absence of platform functionality, not the name
|
|
of platforms.
|
|
|
|
* Out-of-tree builds now work (issue #265).
|
|
|
|
== iperf 3.0.11 2015-01-09 ==
|
|
|
|
* User-visible changes
|
|
|
|
* Added -1 / --one-off flag, which causes the iperf3 server to
|
|
process one client connection and then exit. Intended primarily
|
|
for bwctl integration (issue #230).
|
|
|
|
* Added various minor bug fixes (issues #231, #232, #233).
|
|
|
|
* Added 30-second timeout for UDP tests if unable to establish UDP
|
|
connectivity between sender and receiver (issue #222).
|
|
|
|
== iperf 3.0.10 2014-12-16 ==
|
|
|
|
* User-visible changes
|
|
|
|
* Fixed the build on MacOS X Yosemite (issue #213).
|
|
|
|
* UDP tests now honor the -w option for setting the socket buffer
|
|
sizes (issue #219).
|
|
|
|
* Developer-visible changes
|
|
|
|
* Added an RPM spec file plus functionality to fill in the version
|
|
number.
|
|
|
|
* Fixed potential filename collision with a system header (issue
|
|
#203).
|
|
|
|
== iperf 3.0.9 2014-10-14 ==
|
|
|
|
* User-visible changes
|
|
|
|
* Fixed a series of problems that came from attempting a UDP test
|
|
with a pathologically large block size. This put the server into
|
|
an odd state where it could not accept new client connections.
|
|
This in turn caused subsequent client connections to crash when
|
|
interrupted (issue #212).
|
|
|
|
* Developer-visible changes
|
|
|
|
* None.
|
|
|
|
== iperf 3.0.8 2014-09-30 ==
|
|
|
|
* User-visible changes
|
|
|
|
* Updated license and copyright verbage to confirm to LBNL Tech
|
|
Transfer requirements. No substantive changes; license remains
|
|
the 3-clause BSD license.
|
|
|
|
* Developer-visible changes
|
|
|
|
* None.
|
|
|
|
== iperf 3.0.7 2014-08-28 ==
|
|
|
|
* User-visible changes
|
|
|
|
* A server bug where new connections from clients could disrupt
|
|
running tests has been fixed (issue #202).
|
|
|
|
* Rates now consistently use 1000-based prefixes (K, M, G), where
|
|
sizes of objects now consistently use 1024-based prefixes (issue #173).
|
|
|
|
* UDP tests with unlimited bandwidth are now supported (issue #170).
|
|
|
|
* An interaction between the -w and -B options, which kept them from
|
|
working when used together, has been fixed (issue #193).
|
|
|

== iperf 3.0.6 2014-07-28 ==
|
|
|
|
* User-visible changes
|
|
|
|
* Several bugs that kept the -B option from working in various
|
|
circumstances have been fixed (issue #193).
|
|
|
|
* Various compatibility fixes for OpenBSD (issue #196) and
|
|
Solaris (issue #177).
|
|
|
|
* Developer-visible changes
|
|
|
|
* The {get,set}_test_bind_address API calls have been added to
|
|
expose the -B functionality to API consumers (issue #197).
|
|
|
|
== iperf 3.0.5 2014-06-16 ==
|
|
|
|
* User-visible changes
|
|
|
|
* Erroneous output when doing --json output has been fixed (this
|
|
problem was caused by an attempt to fix issue #158).
|
|
|
|
* The maximum test running time has been increased from one hour to
|
|
one day (issue #166).
|
|
|
|
* Project documentation has been moved to GitHub Pages at this URL:
|
|
http://software.es.net/iperf/.
|
|
|
|
* A bug that caused CPU time to be computed incorrectly on FreeBSD
|
|
has been fixed.
|
|
|
|
* A timing issue which caused measurement intervals to be wrong
|
|
with TCP tests on lossy networks has been fixed (issue #125).
|
|
|
|
* Newer versions of autoconf / automake / libtool are now used by
|
|
default (issue #161).
|
|
|
|
* JSON output now indicates whether the test was run in --reverse
|
|
mode (issue #167).
|
|
|
|
* It is now possible to get (most of) the server-side output at
|
|
the client by using the --get-server-output flag (issue #160).
|
|
|
|
* Developer-visible changes
|
|
|
|
* automake/autoconf/libtool have been updated to more recent
|
|
versions. AM_MAINTAINER_MODE is now used to avoid requiring these
|
|
tools at build-time.

== iperf 3.0.4 was not released ==
|
|
|
|
== iperf 3.0.3 2014-03-26 ==
|
|
|
|
* User-visible changes
|
|
|
|
* Due to several oversights, the source code archive for iperf 3.0.2
|
|
was distributed as an uncompressed tarball, despite having an
|
|
extension (".tar.gz") that indicated it was compressed. The
|
|
release generation procedure has been changed to avoid this
|
|
problem going forward.
|
|
|
|
* Summary structures in the JSON output are now included, even if
|
|
there is only one stream. This change makes consuming the JSON
|
|
output easier and more consistent (issue #151).
|
|
|
|
* A possible buffer overflow in iperf_error.c has been fixed (issue
|
|
#155).
|
|
|
|
* Developer-visible changes
|
|
|
|
* Example programs now build correctly, after having been broken in
|
|
the 3.0.2 release (issue #152).
|
|
|
|
== iperf 3.0.2 2014-03-10 ==
|
|
|
|
* User-visible changes
|
|
|
|
* The iperf3 project has been moved to GitHub, and various URLs in
|
|
documentation files have been changed to point there.
|
|
|
|
* iperf3 now builds on Linux systems that do not support
|
|
TCP_CONGESTION. Most notably this allows iperf3 to work on CentOS
|
|
5.
|
|
|
|
* An abort on MacOS 10.9 has been fixed (issue #135).
|
|
|
|
* Added -I flag for the server to write a PID file, mostly useful for
|
|
daemon mode (issue #120).
|
|
|
|
* A bug that could break some TCP tests on FreeBSD has been fixed.
|
|
|
|
* TCP snd_cwnd output is now printed by default on Linux (issue #99).
|
|
|
|
* In JSON output, the --title string no longer has a colon and two
|
|
spaces appended (issue #139).
|
|
|
|
* A buffer for holding formatted numeric values is now
|
|
properly-sized so that output is not truncated (issue #142).
|
|
|
|
* Developer-visible changes
|
|
|
|
* Some memory leaks have been fixed.
|
|
|
|
* A -d flag enables debugging output.
|
|
|
|
* A .gitignore file has been added.
|
|
|
|
* libtoolize is now invoked correctly from the bootstrap.sh script.
|
|
|
|
* The test unit format can now be set from the API (issue #144).
|
|
|
|
* libiperf is now built as both shared and static libraries.
|
|
|
|
* In the JSON output, the "connection" structures are now stored as
|
|
an array in the "start" block, instead of overwriting each other.
|
|
While technically an incompatible API change, the former behavior
|
|
generated unusable JSON.
|
|
