Each RELA section contains an array of Elf32_Rela entries as you know, but is also tied to a certain other section. r_offset is an offset into that other section (in this case – it … Read more
Your distro configured gcc with –enable-default-pie, so it’s making position-independent executables by default, (allowing for ASLR of the executable as well as libraries). Most distros are doing that, these days. You actually are making a shared object: PIE executables are sort of a hack using a shared object with an entry-point. The dynamic linker already … Read more
The R_X86_64_32S and R_X86_64_64 are names of relocation types, for code compiled for the amd64 architecture. You can look all of them up in the amd64 ABI. According to it, R_X86_64_64 is broken down to: R_X86_64 – all names are prefixed with this 64 – Direct 64 bit relocation and R_X86_64_32S to: R_X86_64 – prefix … Read more
