Exercises and sample created while learning eBPF.

• Learning eBPF book by Liz Rice
• Repository of sample code from the book
• eBPF website
• BPF Compiler Collection (BCC)

You can follow the instructions from Liz Rice's sample code repository

Alternatively you can install the tools manually.

• Install BCC (needed to run the Python examples). Find instructions for your OS
• Install clang compiler or LLVM
• Install libbpf (needed to compile the C examples)

I went with the following options for my local setup:

• Install Ubuntu Desktop 22.04 on a virtual machine (using VMWare Workstation Player)
• Installed bcc tools using: sudo apt-get install bpfcc-tools linux-headers-$(uname -r)
  • Note: The bcc install instructions for Ubuntu warn that packages may be out of date and you should build from source to get the most up-to-date version. But I wasted a lot of time debugging compiler errors when I built from source that I prefered to risk it with the package manager.
• Installed clang using: sudo apt install clang (probably redundant since I also installed llvm)
• Installed llvm using sudp apt install llvm
• Installed libbpf using sudo apt install libbpf-dev
  • If building from source instead of a package manager, may also need to install libelf-dev and/or other dependencies
• Installed bpftool by building from source:
  • Cloned the repo in my home directory: git clone --recurse-submodules https://github.com/libbpf/bpftool.git
  • Then cd bpftool/src
  • Then make install
