Hi, This is the continuation of the work Eric started for handling "p_memsz > p_filesz" in arbitrary segments (rather than just the last, BSS, segment). I've added the suggested changes: - drop unused "elf_bss" variable - report padzero() errors when PROT_WRITE is present - refactor load_elf_interp() to use elf_load() This passes my quick smoke tests, but I'm still trying to construct some more complete tests... -Kees Eric W. Biederman (1): binfmt_elf: Support segments with 0 filesz and misaligned starts Kees Cook (3): binfmt_elf: elf_bss no longer used by load_elf_binary() binfmt_elf: Provide prot bits as context for padzero() errors binfmt_elf: Use elf_load() for interpreter fs/binfmt_elf.c | 192 ++++++++++++++++++------------------------------ 1 file changed, 71 insertions(+), 121 deletions(-) -- 2.34.1
