    [$] Spectre revisits BPF
    It has been well over three years now since the
    Spectre hardware
    vulnerabilities were disclosed    , but Spectre is truly a gift that keeps on
    giving. Writing correct and secure code is hard enough when the hardware
    behaves in predictable ways; the problem gets far worse when processors can
    do random and crazy things. For an illustration of the challenges
    involved, one need look no further than the BPF vulnerability described in
    this
    advisory    , which was fixed in the 5.13-rc7 release.
