== 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).
|
|
|
|
* Developer-visible changes
|
|
|
|
== 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.
|
|
|
