In this session we will create a small toy dynamic linker/loader, which allows importing and executing any piece of pre-compiled binary code. Imagine you have a binary blob from an obscure system with no toolchain to utilize it. Or you're designing a bespoke sandbox to research a piece of malware.

Along the way we will learn how runtime linking works and how executables and shared libraries are combined into a single application. We will dissect the ELF file format, implement code relocations and stub external dependencies. In the end we will have a small, but fully working standalone program, which can load an external piece of code and execute it.
