Currently, kallsyms kernel code copes with symbols with the same name by indexing them according to their position in vmlinux and requiring to provide an index of the desired symbol. This is not really quite reliable and is fragile to any features performing symbol or section manipulations such as FG-KASLR.
Ah, here's the reasoning, stuff like this should go into the 0/X message too, right?
Anyway, what is currently broken that requires this? What will this make easier in the future? What in the future will depend on this?
- FG-KASLR will depend and probably some more crazy hardening stuff. And/or perf-based function/symbol placement, which is in the "discuss and dream sometimes" stage.
I have no idea what "FG-KASLR" is. Why not submit these changes when whatever that is is ready for submission?
