aya,aya-obj: cache feat probed info fields 
Cached probed for ProgramInfo fields instead of exposing it through
global FEATURE. Probing operation happens on cache miss, which happens
when first accessing the field, *and* if the field is 0. No need to
probe if non-zero.

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.
