  • Mprotect stops any read and write and execute access to memory in both user and kernel lands (only rx or wx). Stuff like web browsers won’t work unless you have a program to mark it in elf to not use pax. However, this kills a lot of exploits with that turned on by itself (though there are probably work arounds if you are developing exploits which the other features would hopefully catch). That’s why people installed 3rd party unmainlined security patches, but that’s just me maybe idk.

    I am having a hard time following what this does or why this is desirable. You’re saying there’s a patch this thing provides that … disables memory access … unless a flag is set in an executable … which will then bypass the security?













  • Gonna just stream of consciousness some stuff here:

    Been thinking lately, especially as I have been self-hosting more, how much work is just managing data on disk.

    Which disk? Where does it live? How does the data transit from here to there? Why isn’t the data moving properly?

    I am not sure what this means, but it makes me feel like we are missing some important ideas around data management at personal scale.
