ELF

This repository is my attempt to get a better understanding of ELF binaries. It loosely follows the ELF32 standard laid out in the TIS Portable Formats Specification 1.1, and updates various things for our modern 64-bit world.

Currently, all this does is write bytes in ELF64 format for a binary file named b.out. This binary contains only the minimum necessary: the ELF header, program header, and 7 bytes of shellcode that call exit(0). There's (not yet) actual .data, .bss, or .text sections (or any of the other sections). The binary it outputs is 127 bytes in size.

Usage

make
./elf
./b.out
echo $?

Future

• Add proper sections?
• Run more interesting operations?
• Add ARM support?
