| | | | | Introduction ELF is the file format used for object files (.o's), binaries, shared libraries and core dumps in Linux. It's actually pretty simple and well thought-out. ELF has the same layout for all architectures, however endianness and word size can differ; relocation types, symbol types and the like may have platform-specific values, and of course the contained code is arch specific. An ELF file provides 2 views on the data it contains: A linking view and an execution view. Those two views can be accessed by two headers: the section header table and the program header table. Linking view: Section Header Table (SHT) The SHT gives an overview on the sections contained in the ELF file. Of particular interest are REL sections (relocations), SYMTAB/DYNSYM (sym... | |

In this tutorial I will present all of the techniques I know (and use) to reduce the size of executables. | ||
