But what does it actually look like? Does the stack always grow downwards? What is vDSO? How does address space layout randomization come into play? How do JIT compilers put code in memory and execute it? What else is mapped into the address space of programs? In this talk, I aim to unravel the complexities of process address space using the Linux kernel as an example.
