Yeah, you could make a smart symbol sorting hash program, increasing complexity. Now it's a hack on top of a hack. This rewriting also complicates mounting your libraries as read-only (ie, immutable system). If it's worth doing, surely the rest of the libraries would benefit as well. From a performance standpoint, it's pretty quick for libc, how slow will it be to do this for all libraries? We have ASLR; is there a fundamental reason why ASLR can't be modified/extended/repurposed to achieve the same goal?
