inet-tool

The tool to manage SK_LOOKUP program.

Dependencies:

apt install \
    build-essential \
    clang \
    clang-format \
    lcov \
    libc6-dev-i386 \
    libz-dev \
    python3-virtualenv \
    virtualenv

Clang is needed to compile C into the eBPF program.

First, you need to run experimental kernel with SK_LOOKUP patches. For example:

cd /tmp
git clone https://github.com/jsitnicki/linux.git --branch bpf-inet-lookup --depth 1

Then you can build the inet-tool:

(cd /tmp/linux && make headers_install && make -C tools/lib/bpf)
make KERNEL_DIR=/tmp/linux

Tu run tests (requires root):

sudo make test
