integration-test: kernel_assert anti-condition
Rather than emitting a warning, assert the inverse of the condition when
the current kernel version is lower than required. This strengthens the
assertions made by our tests (provided we run them over kernel versions
before and after the listed version, which is not yet the case).

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 --cache-dir <CACHE_DIR> <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.
