History

tyrone-wu 88f5ac3114 aya,obj,int-test: revamp ProgramInfo be more friendly with older kernels Purpose of this commit is to add detections for whether a field is available in `ProgramInfo`. - For `program_type()`, we return the new enum `ProgramType` instead of the integer representation. - For fields that we know cannot be zero, we return `Option<NonZero*>` type. - For `name_as_str()`, it now also uses the feature probe `bpf_name()` to detect if field is available or not. - Two additional feature probes are added for the fields: - `prog_info_map_ids()` probe -> `map_ids()` field - `prog_info_gpl_compatible()` probe -> `gpl_compatible()` field With the `prog_info_map_ids()` probe, the previous implementation that I had for `bpf_prog_get_info_by_fd()` is shortened to use the probe instead of having to make 2 potential syscalls. The `test_loaded_at()` test is also moved into info tests since it is better related to the info tests. `aya::programs::Programs::prog_type(&self)` now returns `ProgramType` instead of the generated FFI from aya-obj. Also previously, `loaded_programs()` could be accessed either through `aya` or `aya::programs`. To avoid confusion and duplicate export of the item, the function should now only be exposed through `aya::programs`.		3 weeks ago

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:

rustup toolchain install nightly
rustup target add {aarch64,x86_64}-unknown-linux-musl
cargo install bpf-linker
libelf-dev (libelf-devel on rpm-based distros)
llvm (for llvm-objcopy)
(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.
