nondeterministic symbols relocation

[Giuseppe Scrivano]

Hi everybody,

I noticed that ld relocates symbols assigning them always the same
values in a deterministic way.  I am quite sure this is the desired
behaviour but wouldn't be better to add a bit of randomness?
Buffer overflow exploits can take advantage to know in advance the
position of a symbol, it will not solve completely the problem but
surely it will make things harder.

Does something similar already exist?  Is it a reasonable idea?

Thanks,
Giuseppe
