algorithm selection) option to work on FreeBSD for free, starting with
FreeBSD 9. Update various documentation places to note this. One
specifies the congestion algorithm in the same was on Linux, although
the names of the algorithms are (at least in the general case) different.
"sysctl net.inet.tcp.cc" on FreeBSD provides a list of available
algorithms, which are implemented as loadable kernel modules.
Rename the --linux-congestion long option to --congestion (retaining
the old option as a deprecated synonym).
not including it.
To fix this required us to change config.h to iperf_config.h (to
avoid potential filename collisions with this generic name). Then
iperf.h could include this.
Adjust the existing header file inclusions to track this, and also
canonicalize their inclusion to be at the top of *.c files.
As with several other recent commits, don't check explicitly for an
OS platform, but rather detect the various API bits that are used
to implement CPU affinity setting.
We check at configure-time to see if IPV6_FLOWLABEL_MGR is defined
in <linux/in.6>, if it is we set a HAVE_FLOWLABEL CPP symbol to
turn on conditional compilation of the support for this feature.
Rather than checking for anything Linux-specific at configure-time,
see if TCP_CONGESTION is defined in <netinet/tcp.h> and if so define
a CPP variable HAVE_TCP_CONGESTION, which we then use to enable
conditional compilation of the code for this feature.
These macros were never used anywhere in iperf3 anyways, and
conflicted with macro definitions that were in FreeBSD's system
headers.
Bump copyright date and add a comment to inclusion guard while here.
Rather than doing checks for platforms that we believe support SCTP,
instead look for an indication (notably the presence of <netinet/sctp.h>)
that it's supported. This makes the conditionals for SCTP more obvious.
In addition, it opens up the possibility that SCTP might work on some
new OS that's not FreeBSD or Linux.
This change may force some additional build-time requirements on Linux,
such as lksctp-tools-devel on CentOS / Fedora or libsctp-dev on
Ubuntu.
Committing this first cut for review and to enable testing on multiple
platforms. So far this works correctly on Linux (SCTP support) and
MacOS (no SCTP support).
Put the sphinx-generated docs/Makefile under revision control like it
should have been from the start (requires some changes and fixes
to .gitignore).
Change project name from iperf to iperf3 in a few generated places in
the documentation pages, most notably the page headers.

Add a few API calls to the client-side example program so we can
exercise recently-added JSON-related functionality.

Revert part of earlier change.
We still want to save the JSON for libiperf consumers that might want it,
but preserve the prior behavior of writing that JSON to stdout. This
maintains (roughly) the behavior of older libiperf, in which libiperf
consumers (such as the iperf3 executable) do not need to explicitly print
the JSON if that's all they're doing with it.

Allow consumers of libiperf3 to get the JSON output for a just-completed test.
This changes the behavior of iperf_json_finish() so that it no longer
outputs JSON output, but saves the rendered output in a NUL-terminated
string buffer. After calling iperf_run_server() or iperf_run_client(),
the client application should check iperf_get_test_json_output() to see
if it returns a non-NULL pointer. If so, there is JSON data available
for it to print or otherwise consume. The buffer is automatically
deallocated when the containing iperf_test structure is deallocated
with iperf_free_test().
Also adds a new API call iperf_get_test_outfile() to find the output
FILE* structure.
Modifies the iperf3 application to use the new API. Users of iperf3
will not notice any functional change.
No effect in "normal" output mode (non-JSON).
iperf_parse_arguments(). Basically we need to initialize the
output stream in the iperf_test structure regardless of whether
iperf_parse_arguments() gets called; some programs (in particular
the programs in the examples/ directory and bwctl) don't do this
(and indeed should not need to).
This problem was introduced in the solution for Issue #119; the fix
needs to be merged to any codeline where fixes for Issue #119 go.
This works for both client and server side (in the case of the server,
either for daemon or non-daemon mode).
Consistifies a few places that were using printf instead of iprintf.
Fixes Issue 119.
