They seem not. Just one line is nothing. Need to read the f info about kernel.
- jcelerier 7y ago
  yes, that was tongue in cheek - actual work is done by people writing the kernel

Thank you for that website. As I disable mitigations on all my personal hardware, this saved me a bit of time when this whole thing started and has served as a nice quick reference since.

Isn't mitigations=off enough on newer kernels?

  One of the article's comments says so.

  Yes. Its also been added into various LTS versions about five or six months ago. https://cdn.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.68 https://cdn.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.... https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.176 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.1... https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.119 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.... https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.43 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.19.... ctrl+f: cpu/speculation: Add 'mitigations=' cmdline option

  it is, but I know a fair amount of people on older distros - ubuntu 16.04, 18.04, etc... whom may have some flags available but not mitigations=off which is a more recent addition

Big thanks for making the website. I stumbled upon it a few days ago and I'm pretty happy that somebody pointed my attention towards this. The parameter list could be even reduced to fewer elements as mitigations=off covers nopti, nospectre_v1, nospectre_v2, l1tf=off, nospec_store_bypass_disable and mds=off.[1] [1] https://github.com/torvalds/linux/blob/master/Documentation/admin-guide/kernel-parameters.txt#L2629 https://github.com/torvalds/linux/blob/master/Documentation/...

  That seems to depend on kernel version. So just add them all. Better safe than sorry... I mean... unsafe than sorry.

That looks cool. Always wanted to know though, do you benefit something from such websites? Just interested, thanks!
- brirec 7y ago
  As the owner of a couple vanity domains for no useful purpose, no, I don’t “benefit” from it. In fact, each domain costs me a small amount of money. But the amusement I get from them makes it worth it. :)

    As someone also with a few dozen vanity domains. The benefit is learning how to manage multiple web properties with minimum resources. It costs me about $500/year in domain registration alone. I would consider it my hobby as well, but it makes us a shoe-in candidate for a lot of technical positions because we dont need to tell we can simply show.

      Why don't you put them on a tld that'll give you cheap domains?
      - o-__-o 7y ago
        Then they’re not vanity domains anymore (; I’ve been doing this for 20 years, all discounts found and baked in. FWIW all of my demo sites since last summer use .xyz before they become full fledged vanity domains
