It’s funny, the way you talk about it I’d guess it was an exploit of some sort, but it looks like the “mseal()” syscall was introduced in the 6.10 kernel to MITIGATE exploits. A quick search on the internet (not YouTube) gave me an idea of what it is. It’s a new syscall to mitigate (or prevent) attacks on a process’s memory. It was introduced by a Google engineer to improve Chromium security but it obviously is something that glibc has taken advantage of and will benefit many more things. Official kernel documentation: The commit: A blog post about it: I rarely search YouTube to learn about tech things like this. Sites like LWN and Phoronix often discuss these kinds of things, maybe start there next time. Don’t use generative AI at all to learn, either. -- Jonathan Billings |
