Andre Fredette f5d4fdedba Exercise all new TCX APIs in the TCX integration test
Also removed unused code in the tcx eBPF program.

I've manually verified that all the programs get attached in the correct
order.

TODO: Add code to the integration test to automatically verify that the
programs are attached in the correct order after the API based on the
BPF_PROG_QUERY syscall has been implemented.

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

You'll need:

  1. rustup toolchain install nightly
  2. rustup target add {aarch64,x86_64}-unknown-linux-musl
  3. cargo install bpf-linker
  4. libelf-dev (libelf-devel on rpm-based distros)
  5. llvm (for llvm-objcopy)
  6. (virtualized only) qemu

Usage

From the root of this repository:

Native

cargo xtask integration-test local

Virtualized

cargo xtask integration-test vm <KERNEL IMAGE>

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.
