Andrii Nakryiko d54e0f6c1a bpf: improve stack slot state printing ... Improve stack slot state printing to provide more useful and relevant information, especially for dynptrs. While previously we'd see something like: 8: (85) call bpf_ringbuf_reserve_dynptr#198 ; R0_w=scalar() fp-8_w=dddddddd fp-16_w=dddddddd refs=2 Now we'll see way more useful: 8: (85) call bpf_ringbuf_reserve_dynptr#198 ; R0_w=scalar() fp-16_w=dynptr_ringbuf(ref_id=2) refs=2 I experimented with printing the range of slots taken by dynptr, something like: fp-16..8_w=dynptr_ringbuf(ref_id=2) But it felt very awkward and pretty useless. So we print the lowest address (most negative offset) only. The general structure of this code is now also set up for easier extension and will accommodate ITER slots naturally.
