Dave Tucker 5750c3ef7a aya: Add PinnedProgram
This commit adds PinnedProgram which allows the creation of a Program
from a path on bpffs. This is useful to be able to call `attach` or
other APIs for programs that are already loaded to the kernel.
Unfortunately figuring out the concrete type of program is hard given
the information in the kernel so this may not work for all program
types.

Aya Integration Tests

The aya integration test suite is a set of tests to ensure that common usage behaviours work on real Linux distros

Prerequisites

Linux

To run locally all you need is:

  1. Rust nightly
  2. A checkout of libbpf
  3. cargo install bpf-linker
  4. bpftool

Other OSs

  1. A POSIX shell
  2. A checkout of libbpf
  3. rustup target add x86_64-unknown-linux-musl
  4. cargo install bpf-linker
  5. Install qemu and cloud-init-utils package - or any package that provides cloud-localds

Usage

From the root of this repository:

Native

cargo xtask integration-test --libbpf-dir /path/to/libbpf

Virtualized

./test/run.sh /path/to/libbpf

Writing a test

Tests should follow these guidelines:

  • Rust eBPF code should live in integration-ebpf/${NAME}.rs and included in integration-ebpf/Cargo.toml
  • C eBPF code should live in integration-test/src/bpf/${NAME}.bpf.c. It's automatically compiled and made available as ${OUT_DIR}/${NAME}.bpf.o.
  • Any bytecode should be included in the integration test binary using include_bytes_aligned!
  • Tests should be added to integration-test/src/test
  • You may add a new module, or use an existing one
  • Integration tests must use the #[integration_test] macro to be included in the build
  • Test functions should return anyhow::Result<()> since this allows the use of ? to return errors.
  • You may either panic! when an assertion fails or bail!. The former is preferred since the stack trace will point directly to the failed line.
