  • abe088401   bpf: Remove struct bpf_verifier_env argument from print_bpf_insn ... Browse Code »

    We use print_bpf_insn in user space (bpftool and soon perf),
    so it'd be nice to keep it generic and strip it off the kernel
    struct bpf_verifier_env argument.

    This argument can be safely removed, because its users can
    use the struct bpf_insn_cbs::private_data to pass it.

    By changing the argument type we can no longer have clean
    'verbose' alias to 'bpf_verifier_log_write' in verifier.c.
    Instead we're adding the 'verbose' cb_print callback and
    removing the alias.

    This way we have new cb_print callback in place, and all
    the 'verbose(env, ...) calls in verifier.c will cleanly
    cast to 'verbose(void *, ...)' so no other change is
    needed.

  • 7105e828c   bpf: allow for correlation of maps and helpers in dump ... Browse Code »

    Currently a dump of an xlated prog (post verifier stage) doesn't
    correlate used helpers as well as maps. The prog info lists
    involved map ids, however there's no correlation of where in the
    program they are used as of today. Likewise, bpftool does not
    correlate helper calls with the target functions.

    The latter can be done w/o any kernel changes through kallsyms,
    and also has the advantage that this works with inlined helpers
    and BPF calls.

    Example, via interpreter:

    # tc filter show dev foo ingress
    filter protocol all pref 49152 bpf chain 0
    filter protocol all pref 49152 bpf chain 0 handle 0x1 foo.o:[ingress] \
    direct-action not_in_hw id 1 tag c74773051b364165
