Description:
BPF Type Format (BTF),
BPF's debugging information format, has undergone rapid evolution to match
the evolving needs of BPF programs. Jos Marchesi spoke at Kangrejos about some of that work and how it could impact Rust, specifically. He discussed debug information, kernel-specific relocations, and the planned changes to kernel stack unwinding. Each of these will require some amount of work to fully support in Rust, but preliminary signs look promising.
