back to article I want life to be boring, says Linus Torvalds as Linux 4.15 debuts

Linus Torvalds has hit the Go button on version 4.15 of the Linux kernel, blaming the Meltdown and Spectre CPU design flaws for the delay and warning of more pain to come as fixes trickle out for silicon architectures. “This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the …

    If, like me, you wanted to know what retpoline is, and why it matters.

      Did they bounce the idea around before they settled on retpoline?

        Apparently they got the idea from John Lewis.

      Sounds like the kind of stuff you'll get prescribed if you suffer chronic functional constipation.

      Which seems to be the situation for many PCs/Servers out there.

        I would have said it sounds like a hotline for the snakes, crocodiles and lizards.

    Whenever I see a word like that I want to see what it spells backwards. Nothing interesting in this case. Mind you, maybe it's about time someone invented an enilopter. Yes, I want one now.

      Now you have me interested. I want to see an enilopter. I really do.

    Yay for ArchLinux

    Thanks to a really, really small patchset in the distribution itself, it is trivially simple to build my own Linux kernel straight from and with my own configuration. Even better, thanks to following GCC releases really fast, my kernel is now reporting this: "Mitigation: Full generic reptoline". And I am running 4.14.15 - but I bet the distribution will make kernel 4.15 available in the next few weeks (or I can just roll my own - not tempted though, just yet)

      Fedora 27 also showing the same result, but spectre_v1 still vulnerable.

        I am not living under the impression that my computer is not vulnerable to spectre v1. But there is very little I can do about it. I am simply happy that living on the bleeding edge of both kernel and compiler development has, at least once, given me some real benefits. Few distributions make this easy and most are lagging behind, sometimes quite significantly.

      Yes. Marketing would insist on substituting "features" for "vulnerabilities".
