Add support for the following system calls: ioctl (FIONREAD) fcntl (F_GETFL) fcntl (F_SETFL) setsockopt (SOL_IPV6, IPV6_V6ONLY) setsockopt (SOL_TCP, TCP_NODELAY) setsockopt (SOL_SOCKET, SO_REUSEADDR) setsockopt (SOL_SOCKET, SO_BROADCAST) This patch supersedes https://gerrit.fd.io/r/#/c/8765/ Change-Id: I5d5309d9f43d93a990b389d8cb667631de1903fe Signed-off-by: Steven <sluong@cisco.com>
vcl-ldpreload a LD_PRELOAD library that uses the VPP Communications Library (VCL).
User can LD_PRELOAD any application that uses POSIX socket API. This library internally uses libvppcom.so library from VPP project.
HowTo
If VPP is not installed, but rather built in a separate directory, you can use the VPP_DIR 'configure' argument.
# 1. Set environment variables for source
cd vpp/extras/vcl-ldpreload
source ./env.sh
# 2. Change to VPP source directory and build
- Change director and modify uri.am to enable socket_test program
cd $VPP_DIR
perl -pi -e 's/noinst_PROGRAMS/bin_PROGRAMS/g' $VPP_DIR/src/uri.am
- Build VPP release
make install-dep wipe-release bootstrap dpdk-install-dev build-release
# 2. Build LD_PRELOAD library against VPP build above
## This does not install the LD_PRELOAD library in your system.
## Instead it will be referenced from the build directory set in VCL_LDPRELOAD_LIB
cd $LDP_DIR/vcl-ldpreload/src
autoreconf -i -f
./configure VPP_DIR=$VPP_DIR
make
```bash
# 3. Running the demo
## Run test script without parameters to see help menu:
cd $VPP_DIR/test/scripts
./socket_test.sh
# 4. Docker iPerf examples.
## These launch xterms. To quit, close xterms and run following docker kill cmd (WARNING: This will kill all docker containers!) 'docker kill $(docker ps -q)'
## Docker iPerf using default Linux Bridge
./socket_test.sh -bi docker-kernel
## Docker iPerf using VPP
./socket_test.sh -bi docker-preload
