## Build and Run

Build code that gets injected into eBPF:
```sh
CARGO_TARGET_DIR=target/bpf cargo +nightly-2022-10-10 rustc --package=bpf-recorder --bin=bpf-recorder-kern --features=kern --no-default-features --target=bpfel-unknown-none -Z build-std=core --release -- -Cdebuginfo=2 -Clink-arg=--disable-memory-builtins -Clink-arg=--keep-btf
```

After that, build `bpf-recorder` binary:
```sh
cargo build --bin bpf-recorder --release
```
