I'm a bit confused by these two statements:
> Uses of cBPF are unprivileged
> But other Spectre variants kept showing up, so it was eventually decided to add a configuration option to disable unprivileged BPF completely
Is this saying that on modern kernels, BPF requires privilege to be used, even though BPF itself doesn't use any privileges?
