2.0.12 change set (as of June 25th 2018) o Change the unicast TTL default value from 1 to the system default (to be compatable with previous versions.) Mulitcast still defaults to 1. o adpative formatting bug fix: crash occurs when values exceed 1 Tera. Add support for Tera and Peta and eliminate the potential crash condition o configure default compile to include isochronous support (use configure --disable-isochronous to remove support) o replace 2.0.11's --vary-load option with a more general -b option to include <mean>,<stdev>, e.g. -b 100m,40m, which will pull from a log normal distribution every 0.1 seconds o fixes for windows cross compile (using mingw32) o compile flags of -fPIE for android o configure --enable-checkprograms to compile ancillary binaries used to test things such as delay, isoch, pdf generation o compile tests when trying to use 64b seq numbers on a 32b platform o Fix GCC ver 8 warnings 2.0.11 change set (as of May 24th, 2018) o support for -b on server (read rate limiting) o honor -T (ttl) for unicast. (Note: the default value is 1 so this will impact unicast tests that require routing) o support for --isochronous traffic with optional frames per second, mean and variance uses a log normal distribution (requires configure w/-enable-isochronous and compile) o support for --udp triggers (requires configure w/ --enable-udptriggers, early code with very limited support) o support for --udp-histogram with optional bin width and number of bins (default is 1 millisecond bin width and 1000 bins) o support for frame (burst) latency histograms when --isochronous is set o support for --tx-sync with -P for synchonrized writes. Initial use is for WiFi OFDMA latency testing. o support for --incr-dstip with -P for simultaneous flows to multiple destinations (use case is for OFDMA) o support for --vary-load with optional weight, uses log normal distribution (requires -b to set the mean) o support for --l2checks to detect L2 length errors not detected by v4 or v6 payload length errors (requires linux, berkeley packet filters BPFs and AF_PACKET socket support) o support for server joining mulitcast source specific multicast (S,G) and (*,G) for both v4 and v6 on platforms that support it o improved write counters (requires -e) o accounting bug fix on client when write fails, this bug was introduced in 2.0.10 o slight restructure client/server traffic thread code for maintainability o python: flow example script updates o python: ssh node object using asyncio o python: histograms in flows with plotting (assumed gnuplot available) o python: hierarchical clustering of latency histograms (early code) o man pages updates o Note: latency histograms require client and server system clock synchronization. A GPS disciplined oscillator using Precision Time Protocol works well for this. Signed-off-by: Koen Vandeputte <koen.vandeputte@ncentric.com>
This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to choose your preferred configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Community http://www.openwrt.org
