vmlinux-to-elf

vmlinux-to-elf 이 도구는 vmlinux/vmlinuz/bzImage/zImage 커널 이미지원시 바이너리 블롭 또는 이미 존재하지만 심볼이 제거된 .ELF 파일에서 함수 및 변수 심볼을 복구하여 완전히 분석 가능한 .ELF 파일을 얻을 수 있게 해 줍니다. 이를 위해 이 도구는 커널에서 커널 심볼 테이블kallsyms을 스캔합니다. kallsyms는 거의 모든 커널에 대부분 변경되지 않은 채로 존재하는 압축된 심볼 테이블입니다. 해당 심볼 테이블은 원래 압축되어 있기 때문에 원본 바이너리에는 보이지 않는 문자열도...
