This commit removes memset and memcpy, relying instead on implementations provided by std/compiler-builtins. This commit adds `#![no_builtins]` to all the BPF programs written in Rust, and the same should be propagated to aya-template and all examples in the book and elsewhere before this commit is merged. It turns out that without the `#![no_builtins]` annotation rustc generates LLVM IR that calls LLVM intrinsics rather than libcalls. These may end up as libcalls after lowering, but not before emitting errors in BPF lowering[0]. This works thanks to https://github.com/rust-lang/rust/pull/113716 which causes `#![no_builtins]` to behave similarly to `-fno-builtin` in clang, which was added in https://reviews.llvm.org/D68028 with similar motivation. This commit implies that we now require rustc nightly >= 2023-07-20. [0] https://github.com/llvm/llvm-project/blob/7b2745b/llvm/lib/Target/BPF/BPFISelLowering.cpp#L472-L474 |

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
- (virtualized only)
qemu
Usage
From the root of this repository:
Native
cargo xtask integration-test local
Virtualized
cargo xtask integration-test vm
Writing an integration test
Tests should follow these guidelines:
- Rust eBPF code should live in
integration-ebpf/${NAME}.rs
and included inintegration-ebpf/Cargo.toml
andintegration-test/src/lib.rs
usinginclude_bytes_aligned!
. - C eBPF code should live in
integration-test/bpf/${NAME}.bpf.c
. It should be added to the list of files inintegration-test/build.rs
and the list of constants inintegration-test/src/lib.rs
usinginclude_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 topanic!
instead.
