SPDX-License-Identifier: GPL-2.0 ================================= Linux-specific ELF idiosyncrasies ================================= Definitions =========== "First" program header is the one with the smallest offset in the file: e_phoff. "Last" program header is the one with the biggest offset in the file: e_phoff + (e_phnum - 1) * sizeof(Elf_Phdr). PT_INTERP ========= First PT_INTERP program header is used to locate the filename of ELF interpreter. Other PT_INTERP headers are ignored (since Linux 2.4.11). PT_GNU_STACK ============ Last PT_GNU_STACK program header defines userspace stack executability (since Linux 2.6.6). Other PT_GNU_STACK headers are ignored. PT_GNU_PROPERTY =============== ELF interpreter's last PT_GNU_PROPERTY program header is used (since Linux 5.8). If interpreter doesn't have one, then the last PT_GNU_PROPERTY program header of an executable is used. Other PT_GNU_PROPERTY headers are ignored. |
