Address Space Layout Randomization
Program and dyld
- On program load, the address space offset of the program is randomized between 0x0 and 0x100000
- It always falls on a 0x1000 page boundary
- dyld is included in this sliding section
- The system libraries are now stored in a big cache file, see [[1]]
- This is address randomized at boot time, in many possible places
- The functions retain a fixed offset to each other.
