Towards #707.
|
|
|
|
|
|
The master codeline is once again 3-CURRENT, not 3.3.
|
|
TODO: Need to update some documentation that reflects `-A` is applicable to Windows. @bmah888 to do this.
|
|
* EXIT_SUCCESS and EXIT_FAILURE are defined in stdlib.h, not sysexits.h
so no need to include the latter.
* No need to include pthread.h.
* Remove the no longer used delay() function.
This also removes the reliance on nanosleep().
* Remove get_tcp_windowsize() and set_tcp_windowsize() which are unused.
These days, iperf uses get/setsockopt() with SO_SNDBUF SO_RCVBUF directly.
|
|
Fixes (and based on a patch in) #369, with some reworking by @bmah888 and @pprindeville.
|
|
The getline(3) implementation comes from NetBSD's file(1) command.
This should make compiling work on macOS pre 10.7. Fixes #607.

* Fix warnings about _GNU_SOURCE being redefined.

* Simplify endianness checks
Linux can be built with too many types of C run-time library and it's
not reasonable to have to enumerate all of them, especially since at
least one of them (MUSL) goes out of its way to not be easily
detectable.
Instead, leverage autoconf better for Linux/BSD to detect either
<endian.h> or <sys/endian.h> directly.

* Sys headers should not be included directly
There's usually a top-level header which then includes the sys/
descendent.

Don't make OpenSSL detection error out unless --with-openssl explicitly given.
This fixes the out-of-the-box build on macOS, which doesn't include
headers, etc. for OpenSSL by default. The configure script still
errors out if the user specifies a --with-openssl flag but for some
reason the build host's OpenSSL is broken or can't be used.
* Regen.
|
|
* fix: now --without-openssl configure flags works
enh: if openssl support is required and no valid installation is found, now it raise an error
* enh: added warning if building without openssl (iperf_auth disabled)

* Add configurable timeout for the setup of the control connection.
This is specified using the new --connect-timeout option, with an
integer parameter in ms. The iperf3 client will wait for this
amount of time for the setup of the control connection to the
server. If this option is not given, the OS default for TCP
connection setup is used. Specifying a smaller connection timeout
allows faster detection of a down / unresponsive iperf3 server.
The implementation uses a variation on the timeout_connect()
function from OpenBSD's netcat utility.
Fixes #216.

Follow-up for #517.

Add an optional mode that requires clients to authenticate with the server.
In this mode, clients need to provide a username and a password, which are checked against a password file on the server. The authentication credentials are protected by an RSA public keypair...the encrypted credentials are sent along with the test parameters.
Operationally the use of this feature places the following additional requirements on the build and installation of iperf3:
o The presence of the OpenSSL headers and libraries to build iperf3, and the libraries available on the client and server at runtime.
o Generation of an RSA public keypair; the private part is used by the server and the public part must be distributed to the clients.
o Username/password pairs for all authorized users, to be stored in a file on the server.
o Loose time synchronization between the server and clients (to within approximately 30 seconds).
o Appropriate command-line flags given on the client and server.
Note that iperf3 can be built and run as before, without fulfilling any of these requirements.
Partial documentation for this feature is included in this commit. It is anticipated that additional documentation text and editing will follow this merge.
Submitted by @ralcini. First suggested by @codyhanson in pull request #242.

* Remove unused hstrerror(), bad nanosleep() message in configure.ac (#503)
* Remove dead code involving h_errno and hstrerror()
h_errno was formerly set as a side effect of a failed
gethostbyname(3) call, but this function has been
deprecated.

malformed JSON string was passed on the control channel. This issue,
present in the cJSON library, was already fixed upstream, so was
addressed here in iperf3 by importing a newer version of cJSON (plus
local ESnet modifications).
Discovered and reported by Dave McDaniel, Cisco Talos.
Based on a patch by @dopheide-esnet, with input from @DaveGamble.

Add some documentation for fair-queueing per-socket pacing.
For #325.
commit 5571059870f7aefefb574816de70b6406848888f
Author: Bruce A. Mah <bmah@es.net>
Date: Tue May 24 11:55:44 2016 -0400
Change the fair-queueing socket pacing logic in response to feedback.
By default, on platforms where per-socket pacing is available, it
will be used. If not available, iperf3 will fall back to application-
level pacing.
The --no-fq-socket-pacing option can be used to forcibly disable
fair-queueing per-socket pacing. (The earlier --socket-pacing option
has been removed.)
Tested on CentOS 7, more testing on other platforms is required to
be sure it didn't break the old application-level pacing behavior.
For #325.

commit 200d3fe3917b3d298bdf52a0bde32c47cf2727b0
Author: Bruce A. Mah <bmah@es.net>
Date: Sat Apr 16 02:41:32 2016 -0400
Checkpoint for initial work on #325 to add socket pacing.
This works only on Linux and depends on the availability of
the SO_MAX_PACING_RATE socket option and the fq queue discipline.
Use --socket-pacing to use SO_MAX_PACING_RATE instead of the
default iperf3 user-level rate limiting; in either case, the
--bandwidth parameter controls the desired rate.
Lightly tested with both --tcp and --udp, normal and --reverse.
Real testing requires analysis of packet timestamps between
multiple hosts.

Solaris implements an (older?) version of the API for SCTP_MAXSEG,
which takes an integer argument rather than a struct sctp_assoc_val.
We need to test for that and handle it appropriately. There are some
signs it doesn't even work correctly if we do this, so quietly ignore
errors that happen if the OS complains it's unsupported.
Also, Solaris doesn't support SCTP_DISABLE_FRAGMENTS even though it
defines the preprocessor symbol for this. Rather than aborting when
we try to unsuccessfully unset this option, just ignore the error.
Lightly tested with SCTP over IPv6 on localhost.

Contains an alternate implementation of previously-submitted patches
to set the maximum segment size and no-delay options.
As a result of this change, SCTP functionality on Linux will generally
require the libsctp library (on CentOS and similar distributions this
is provided by the lksctp-tools RPM).
Part of #131.

the best thing to do from a code hygeine standpoint, it's too
painful to try to get right for now.
Fixes #174 (second try).

Only do -Wall by default if on GCC (or something that looks like
GCC, such as clang/llvm).
Turn on -Werror so we can get some better error-checking, but
we also need -Wno-deprecated-declarations at least for MacOS,
because daemon(3) is deprecated starting with MacOS 10.5.
Fixes #174 (I think).

Resolves #161.

These simplify the release process because they eliminate a manual
file-editing step.

There's still a bunch of OS-dependent fu because every platform that
supports sendfile(2) does it differently.
|
|
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.

Makefile infrastructure. So get rid of the autoconf goop that sets
it.

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.
