integration-ebpf: invalidate on bpf-linker
Extract the symlink-to-bpf-linker logic from integration-test to xtask
and use it in a new build script in integration-ebpf, causing ebpf
probes to be rebuilt when bpf-linker changes. Previously bpf-linker
changes would rebuild integration-test, but not integration-ebpf,
resulting in stale tests.

Note that this still doesn't address the possibility that a new
bpf-linker is added to the PATH ahead of the cached one. Solving this in
the general case would require rebuild-if-changed-env=PATH *and*
rebuild-if-changed={every-directory-in-PATH} which would likely mean far
too much cache invalidation.

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. cargo install bpf-linker
  3. bpftool 1

Other OSs

  1. A POSIX shell
  2. rustup target add x86_64-unknown-linux-musl
  3. cargo install bpf-linker
  4. 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

Virtualized

./test/run.sh

Writing an integration test

Tests should follow these guidelines:

  • Rust eBPF code should live in integration-ebpf/${NAME}.rs and included in integration-ebpf/Cargo.toml and integration-test/src/lib.rs using include_bytes_aligned!.
  • C eBPF code should live in integration-test/bpf/${NAME}.bpf.c. It should be added to the list of files in integration-test/build.rs and the list of constants in integration-test/src/lib.rs using include_bytes_aligned!.
  • Tests should be added to integration-test/tests.
  • You may add a new module, or use an existing one.
  • Test functions should not return anyhow::Result<()> since this produces errors without stack traces. Prefer to panic! instead.
