  • Ah yes, the “extended Berkeley Packet Filter”.
    Wikipedia:

    eBPF is a technology that can run programs in a privileged context such as the operating system kernel.

    Phoronix:

    Hornet uses a similar signature verification scheme similar to that of kernel modules. A pkcs#7 signature is appended to the end of an executable file. During an invocation of bpf_prog_load, the signature is fetched from the current task’s executable file. That signature is used to verify the integrity of the bpf instructions and maps which where passed into the kernel. Additionally, Hornet implicitly trusts any programs which where loaded from inside kernel rather than userspace, which allows BPF_PRELOAD programs along with outputs for BPF_SYSCALL programs to run.

    So this is to make kernel-level instructions from userspace (something that’s already happening) more secure.

    The thread linked by the OP is Jarkko Sakkinen (kernel maintainer) seemingly saying “show your work, your patch is full of nonsense” in a patch submitted for review to the Linux kernel.
    Edit: the OP has edited the link, it used to point to this comment in the mailing list chain.
















  • I’d suggest the KDE flavor of Debian, then. Its settings manager is divine, and its software management platform ties every other package management system in (apt/dpkg for Debian, yum for Redhat, pacman for Arch, plus flatpak, nixpkg, and even snaps if you absolutely must). By default starting in Plasma 6.0.

    More to @fmstrat’s point, and to suggest a possible cause your friend had that impression: if you install the Minimal flavor of any distro, you’re going to get a minimal experience.
