Hello, this patch implements strict check on segments order in ELF file. Current implementation doesn't check the order of ELF segments and compute totalsize as difference between last one and the first one. If ELF file has wrong order it allows to re-mmap existing memory region with one from ELF file. Ilya Smith (1): Additional strict check on ELF file. Checks segments are followed in order of 'p_vaddr ' value ascending. It fixes erorr in total_mapping_size with computation total size. This error happens if segments in ELF file are not in order. fs/binfmt_elf.c | 51 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 51 insertions(+) -- 2.14.1
