    [$] Taming the BPF superpowers
    Work toward the signing of BPF programs has
    been finding its way into recent mainline kernel releases; it is intended
    to improve security by limiting the BPF programs that can be successfully
    loaded into the kernel. As John Fastabend described in his "Watching
    the super powers" session     at the 2021 Linux Plumbers Conference,
    this new feature has the potential to completely break his tools. But
    rather than just complain, he decided to investigate solutions; the result
    is an outline for an auditing mechanism that brings greater flexibility to
    the problem of controlling which programs can be run.
