Since apply_relocate_add() requires access to a module's section headers, symbol table, and relocation section indices, Elf information is preserved for livepatch modules and is made accessible by the module loader through -module->klp_info, which is a klp_modinfo struct. When a livepatch module loads, -this struct is filled in by the module loader. Its fields are documented below:: - - struct klp_modinfo { - Elf_Ehdr hdr; /* Elf header */ - Elf_Shdr *sechdrs; /* Section header table */ - char *secstrings; /* String table for the section headers */ - unsigned int symndx; /* The symbol table section index */ - }; +module->klp_info, which is a :c:type:`klp_modinfo` struct. When a livepatch module +loads, this struct is filled in by the module loader.
