Tools and languages
User space helpers and patterns that make building and debugging eBPF programs easier
BCC
BPF Compiler Collection a Python and Lua toolkit that wraps Clang so you can embed small eBPF snippets in scripts and run them with just a few lines of loader code.
BPFTool
The official command-line utility shipped with the kernel source that loads pins inspects and benchmarks eBPF programs and maps from user space.
Tail call
One eBPF program can jump straight into another without returning which lets you chain logic and sidestep the per-program instruction limit while adding almost no overhead.
