These are the Release Notes for revision 2.3pl1 of netperf:
Things changed in this release
*) The bind() call in create_data_socket() in the file nettest_bsd.c
is no longer conditional on the user's specifying an IP address or
port number to which the data socket should be bound. This fixes
the "connection refused" errors in the UDP tests.
*) Some experimental code to allow one to specify a CPU to which the
remote netserver should be bound. This is intended to allow one to
get greater certainty (as in confidence intervals) on SMP
systems. At present the functionality is HP-UX specific.
Submittals of changes for a more general approach are welcomed.
These are the Release Notes for revision 2.3 of netperf:
Things changed in this release
*) The user can now specify local and/or remote port numbers for the
data connection using the -P test-specific option. This is to
support those folks who want to run netperf through those evil,
end-to-end-breaking things known as firewalls... :) This changes
the format of some of the control messages, hence the bump in the
update number in the VUF. While it may be possible to mix 2.3 and
pre-2.3 netperf and netserver, it is not supported.
*) The user can now specify local and/or remote IP addresses for the
data connection using the -I test-specific option. This is to
support those folks who want to run netperf through those evil,
end-to-end-breaking things known as firewalls... :) This changes
the format of some of the control messages, hence the bump in the
update number in the VUF. While it may be possible to mix 2.3 and
pre-2.3 netperf and netserver, it is not supported.
*) Set DL_mumble message priorities in the DLPI tests
*) Fix error return check for getaddrinfo()
*) Those systems with gethrtime() can define -DHAVE_GETHRTIME to use
gethrtime() instead of gettimeofday() and reduce the measurement
overhead when enabling the -DHISTOGRAM functionality.
*) The default for -DHISTOGRAM compilation now adds a UNIT_USEC and
TEN_USEC row and renames TENTH_MSEC to HUNDRED_USEC. If you want
the old behaviour add -DOLD_HISTOGRAM to CFLAGS.
*) Add missing '!' in the recv_udp*_stream so we recognize the end of
a timed test correctly.
*) Replace "||" with "&&" to fix an infinite loop in
recv_tcp_conn_rr() most likely introduced in 2.2pl5.
*) Code has been added to kludge around the bug in Linux getsockopt()
where it almost always returns twice the value for which one
asks unlike virtually every other stack on the face of the
planet. This was doing some unpleasant things to tests in which
confidence intervals were requested.
Things not changed in this release
*) Lots :)

Beware that only invocations are changed that don't set special
values for owner, mode or group!

(IPv6-ready when USE_INET6 - will be revisited when we change USE_INET6 to
something else)
