In ELF, the same integers for two note type represent different meanings if the names they belong to are different. However, get_pt_note_info() doesn't distinguish note types by name space, due to which, for example, any new note type in "VMCOREINFO" name space is wrongly interpretted as NT_PRSTATUS or the unique note type in "VMCOREINFO" name space.
This patch series makes get_pt_note_info() distinguish ELF note types by ELF note names along with cleanups related to this change. For reference: Note Section http://www.sco.com/developers/gabi/latest/ch5.pheader.html#note_section type This word gives the interpretation of the descriptor. Each originator controls its own types; multiple interpretations of a single type value may exist. Thus, a program must recognize both the name and the type to recognize a descriptor. Types currently must be non-negative. The ABI does not define what descriptors mean. --- HATAYAMA Daisuke (3): elf: distinguish ELF note types by ELF note name space elf: swap checking order of VMCOREINFO and VMCOREINFO_XEN elf, sadump: move KEXEC macros from sadump_info.c to elf_info.h elf_info.c | 83 ++++++++++++++++++++++++++++++++++++++------------------- elf_info.h | 3 ++ sadump_info.c | 4 +-- 3 files changed, 59 insertions(+), 31 deletions(-) -- Thanks.
