    NVIDIA issued a security bulletin today regarding their GPU drivers and the Spectre speculative side-channel attacks...

    I would have been appalled if they had said they were vulnerable to variant three

      Tried updating my kernel to 4.14.12 earlier today and it would seem like Nvidia's drivers, including the 384.111 ones, seem to have issues with the generic 4.14.9 and newer 4.14 kernels relating to license changes.

        Well, they do call OpenCL programs "kernels"...

          no issues here, running 4.14.12 and nvidia 390.12 just fine

            <puts on tin foil hat> Isn't in interesting that all these security fixes in the Nvidia drivers came out just after they changed the license to prevent usage of various GPUs in datacenters?

            Those already doing that who figured they could at least just keep running the older driver versions figured wrong.

              There is a fix for that, will be in 4.14.13. Maybe to note better part of the comment

              As always I'm really thrilled to make this kind of change to support the #friends (or however the hot hashtag of today is spelled) from that closet sauce graphics corp.

Doesn't matter now though, I'm gaming on Windows so "not my problem" anymore. If the libtards in Linux-land want to pretend like everything is fine and dandy and Bill Clinton isn't a sexual harasser, then fine. I'm loving my new Android phone too! Think I'm going to shop for a refurbished iPad next... that'll solve all my Linux problems for sure. I got better things to do than argue.
                Would someone be able to translate that into human language?
                I don't speak "batshit insane".

                  Now that's a bummer! According to Alan Cox you cant change an export from _GPL to none_GPL without the approval of all copyright holders (see https://lists.freedesktop.org/archiv...er/028846.html ). The original author of the line "EXPORT_SYMBOL_GPL(cpu_tlbstate);" is Andy Lutomirski (see https://patchwork.kernel.org/patch/5082641/ ) but Thomas Gleixner changed it and Greg Kroah-Hartman approved? Are they risking a inner-kernel copyright fight just to suit nvidia?

                  //EDIT: Two years ago Thomas Gleixner tried the exact same thing but Andy Lutomirski declined: https://marc.info/?l=linux-kernel&m=144312144420420&w=2 - Somebody should tell Greg Kroah-Hartman to revert this ASAP!

                    Well they probably thinked about it, as i see same patch in all kernels - it is in 4.15-rc7 and it goes on in all longterm kernels GKH maintains... as i see he released them now already

                    And it is reported by Google's guy, maybe it is not just to please nvidia driver probably some drivers that google uses somewhere see a problem also... just a guess
