OSI Stack

OSI communication stack, initially written for AVR UART communication.

This implementation intentionally uses raw pointers instead of smart pointers.

The reasoning is that it will be ported to small 8-bit hardware architectures such as AVR/Arduino, with limited support for modern C++.

Layers

Build and Test

First, get the sources:

git clone https://github.com/mihaigalos/osi-stack.git && cd osi-stack

Baremetal

Building and testing is managed by bazel, including dependencies to other repos such as containers (transparent to the end-user).

bazel build //...
bazel test //...

Using Docker

docker run -it --rm --cap-add SYS_PTRACE -v $(pwd):/src -v /tmp:/tmp/bazel docker.pkg.github.com/mihaigalos/docker/bazel /bin/zsh -c "cd /src && bazel --output_base=/tmp/bazel test //..."

Session Layer Authentification

The Session handshake is described in the following diagram:
