Changelog for netperf-2.4.4-1.sles10.i586.rpm :
Fri Nov 16 11:00:00 2007 Bruno Cornec 2.4.4-1.sles10
- Updated to 2.4.4
- The LOC_CPU and REM_CPU tests will report their respective beliefs
as to the number of CPUs present when the verbosity is set to more
than one. This can be used when trying to diagnose issues with CPU
utilization.
- A kind soul who wishes to remain anonymous provided a patch to
enable use of sendfile() on OSX.
- Fix a misplaced \
in a format string of send_tcp_maerts, courtesy
of Alexander Duyck.
- There is an experimental global -r option which will allow one to
include CPU utilization measurements, but make the decision about
hitting confidence based on the result only. The test banner will
reflects this when -r is used.
- It is no longer necessary to specify a file with the global -F
option when running a _SENDFILE test. Netperf will create a
temporary file and populate it with random data and use that. If
running aggregate tests it is strongly suggested one use a -F
option. Otherwise, the overhead spent creating and populating the
temporary file will be included in the CPU utilization calculation.
- The configure script recognizes Solaris 11 and selects the correct
CPU utilization mechanism - or rather it selects the same mechanism
as is used in Solaris 10. Fix courtesy of Andrew Gallatin.
- Convert a number of struct sockaddr_in\'s to struct
sockaddr_storage\'s and add requisite casts to deal with some abort
problems on Windows and perhaps other platforms as well. Kudos to
Alexander Duyck.
- One can now pass a value of \'x\' to the global -f option to specify
the units as transactions per second. This is the default for any
request/response test, which is determined by there being a \"double
`r\'\" in the name - eg \"RR,\" \"rr,\" \"Rr,\" or \"rR.\" At present only
the TCP_RR test actually looks for this to be set.
- One can request bits/bytes per second as the primary output of a
TCP_RR test by setting the global -f option to [kmgKMG] as with any
of the \"STREAM\" tests. This converts the primary throughput metric
to a bitrate (byterate) following the verbosity rules for a STREAM
test. Service demand remains usec/Transaction regardless of the
setting of the global -f option.
A verbosity level of 2 or more will cause the TCP_RR test to report
calculated average RTT latency, transaction rate, and inbound and
outbound transfer rates regardless of the primary units selected
with the global -f paramter. If the primary output is transactions
per second, the reported inbound and outbound transfer rates will
be 10^6 bits per second, otherwise, they honor the setting of the
global -f option.
All of this is EXPERIMENTAL and subject to change without prior
notice in future versions of netperf.
- Replace \"break\" with \"break 2\" in acinclude.m4 for a socklen macro
- The default for the requested socket buffer size is changed from 0
to -1 to enable passing a value of 0 under Windows, which tells that
stack one wishes to enable copy-avoidance.
- Call fflush() on each interim result displayed in demo mode to make
things happier for folks redirecting same to a file. From Dan
Yost.
- In theory each distinct netserver child will have a debug log with
its pid appended to the name, somewhat like what appears to happen
under Windows.
- A new global, command-line option to netperf and netserver has been
added. The -V option will cause netperf/netserver to display its
version and exit.
- Setting -I without setting -i will now implicitly set the iteration
minimum and maximums as if a -i 10,3 were set. Also, some further
sanity checking on the bounds for each is made.
- Fixed a typo in the manual (found by Emir Halepovic) so the
description for the -s and -S options properly specifies they
affect the data connection.

Fri Oct 5 12:00:00 2007 Bruno Cornec 2.4.3-1.sles10
- Updated to 2.4.3
- The UDP_STREAM test includes --enable-demo support, courtesy of
patches from Scott Weitzenkamp.
- The nettest_dns.
* files have been removed from the release and the
repository. Those wishing to perform DNS server tests should
migrate to netperf4 which has better support for DNS test.
- Fixes for compiling under Windows with Mingw/gcc courtesy of Gisle
Vanem.
- A new global option - -N - has been added. When specified, this
option will tell netperf to not bother to try to establish a
control connection with a remote netserver. Instead, netperf will
only attempt to make a data connection to the remote system. By
default, this will be to the \"discard\" service for a \"STREAM\" or
\"SENDFILE\" test, the \"echo\" service for a \"RR\" test and the
\"chargen\" service for a \"MAERTS\" test. Any \"remote\" settings are
changed to reflect their being unused in the test, and a \"no
control\" tag is added to the test banner when -N is specified.
This still needs to be propagated to other test files - at least
for those for which it may make sense.
- The tests in nettest_bsd.c have been altered to not actually take
timestamps and deltas in --enable-histogram unless the verbosity
level has been set to actually display a histogram. This reduces
the overhead measurably, even on systems with \"fast\" time calls,
which _may_ mean that a future release of netperf may have
histogram support enabled by default.
This still needs to be propagated to other test files. Patches
from the community would be most welcome :)
- Eliminate a bogus fprintf from the signal catching routine which
was being executed when both intervals and demo mode were active at
the same time.
- The nettest_ipv6.
* files are no longer included in the source
tar/zip file. IPv6 functionality has been subsumed into the
nettest_bsd.
* files for some time now.
- Use a higher resolution \"time\" source for HISTOGRAM support under
Windows, courtesy of Spencer Frink. Prior to this it had no better
than 10ms granularity which could lead to some rather strange
looking results :)
- A bug fix reporting recv_size rather than send_size in TCP_MAERTS
when CPU utilization was requested.
- A bug fix for buffer filling from a file to properly advance the
buffer pointer when the file is smaller than the send buffer.
- Enable certain UDP tests which previously used unconnected sockets
to use connected sockets. Courtesy of Shilpi Agarwal.
- The OSX CPU utilization code actually gets put into the tarball in
a make dist now :)
- The check to make sure that getaddrinfo returned ai_protocol and/or
ai_socktype\'s matching that which we requested is done for all socket
and/or protocol types and a warning is emitted if it returns any which
do not match.
- The linux CPU affinity code has been made capable of binding to
CPU\'s >=32 on a 32-bit compilation and >=64 on a 64-bit
compilation.
- More complete closing/redirecting of stdin/stdout/stderr/where in
netserver to make it easier to launch netserver at the far-end of a
remote shell. Courtesy of Hans Blom.
- Sendfile changes for Solaris courtesy of Andrew Gallatin.
- \"spec\" file support to generate RPMs courtesy of Martin Brown

Sat Sep 1 12:00:00 2007 Bruno Cornec 2.4.2-1.sles10
- Updated to 2.4.2
- Fixes for floating point format differences, courtesy of George
Davis.
- Additions for CPU util support on MacOS X, courtesy of Anonymous.
- Processor affinity is now supported on AIX 5.3 (perhaps earlier)
via the bindprocessor system call.
- Fixes for test lockups with TCP_CRR and TCP_CC under Windows
courtesy of Dikon Reed.
- Fixes to netcpu_looper.c to get it to actually compile :)
- Have netcpu_looper use the bind_to_specific_processor() call
provided by netlib since that knows about more platforms than the
code in netcpu_looper did. The looper CPU binding will use a
mapping to handle cases where the CPU id\'s on the system may not be
a contiguous space starting from zero. At present, the code that
setups the mapping only knows about retrieving actual CPU ids under
HP-UX.
- The netcpu_sysctl method becomes calibration-free, courtesy of
Andrew Gallatin
