bpfix

End-to-end workflow for diagnosing and repairing eBPF verifier rejections in C, Rust/Aya, libbpf, libbpf-rs, BCC, bpftool, and CI logs from raw verbose verifier logs, BPFix diagnostics, or source/test failures. Use when Codex is asked to fix, explain, or patch verifier errors, verifier logs, BPFIX diagnostics, packet bounds, nullable pointer, stack initialization, reference lifetime, scalar range, pointer provenance, compiler lowering artifact, helper/kfunc/dynptr/iterator, RCU/IRQ/lock, environment capability, or verifier budget failures.
