This invention relates to a method for cross-version binary compatibility of Linux kernel modules, belonging to the field of computer operating system kernels. It includes the following steps: During the compilation phase, the compiler identifies specific keywords (__kabi_reloc_member, __kabi_check_member, __kabi_sizeof) and records instruction offsets, type identifiers, member variable name offsets, and relocation types, generating a .kabi_relocs segment. During the loading phase, the loader parses the .kabi_relocs segment, combines it with module BTF and kernel BTF information, and dynamically repairs instructions based on the relocation type. This invention achieves "compile once, run anywhere" binary compatibility for kernel modules, with the repair operation completed at load time, having no impact on runtime performance.
