Expand description
This module provides functionality to allocate memory with higher randomness on returned addresses.
The most simple approach is to allocate memory multiple times, return the final allocation as the desired memory.
Allocators differ between operating systems. On *nix and BSD-based systems malloc(int) is being called
but does not initialize the allocated spaced. Microsoft Windows uses
VirtualAlloc
allocates and initializes a region of memory pages with zeroes.
FragStrategy implements at least two possible allocation strategies:
- Direct: The algorithm tries to allocate a huge amount of memory space while keeping a certain address distance
- Memory Mapped: anonymous memory is being mapping, the memory address will be randomly selected.
Structs
Frag is being used as control object to load different allocators
according to their strategy
