The fact that > several major distros have it disabled makes me think it's fine. FWIW, it is now disabled in Ubuntu too: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/impish/commit/?h=master-next&id=f3aac5e47789cbeb3177a14d3d2a06575249e14b > But as always, it would be good to check Android. It looks like it's enabled (checking the Pixel 4 kernel image), but it's not specifically mentioned in any of the build configs that are used to construct the image, so I think this is just catching the "default y". I expect it'd be fine to turn this off. I will ask around to see if it's actually used. -- Kees Cook
