Agreed. Going by this version of function-granularity KASLR from 3 years ago:
https://lwn.net/Articles/824307/ https://lwn.net/ml/linux-kernel/20200623172327.5701-1-kristen@linux.intel.com/
The fgKASLR feature looks entirely viable to me. Back then I presumed it would get iterated beyond v3, and then it fell off my radar. :-/
If Kristen or someone else would like to dust this off & submit a fresh version it would be much appreciated!
Thanks,
Ingo
