elf.h had a comment saying: > Notes used in ET_CORE. Architectures export some of the arch register > sets using the corresponding note types via the PTRACE_GETREGSET and > PTRACE_SETREGSET requests. > The note name for these types is "LINUX", except NT_PRFPREG that is > named "CORE". However, NT_PRSTATUS is also named "CORE". It is also unclear what "these types" refers to. To fix these problems, define a name for each note type. The added definitions are macros so the kernel and userspace can directly refer to them. Signed-off-by: Akihiko Odaki <akihiko.odaki@xxxxxxxxxx> --- Changes in v2: - Added a macro definition for each note type instead of trying to describe in a comment. - Link to v1: https://lore.kernel.org/r/20241225-elf-v1-1-79e940350d50@xxxxxxxxxx --- Akihiko Odaki (5): elf: Define note name macros binfmt_elf: Use note name macros powwerpc: Use note name macros crash: Use note name macros crash: Remove KEXEC_CORE_NOTE_NAME arch/powerpc/kernel/fadump.c | 2 +- arch/powerpc/platforms/powernv/opal-core.c | 8 +-- arch/s390/kernel/crash_dump.c | 2 +- fs/binfmt_elf.c | 21 ++++---- fs/binfmt_elf_fdpic.c | 8 +-- fs/proc/kcore.c | 12 ++--- include/linux/kexec.h | 2 - include/linux/vmcore_info.h | 3 +- include/uapi/linux/elf.h | 86 ++++++++++++++++++++++++++++-- kernel/crash_core.c | 2 +- 10 files changed, 111 insertions(+), 35 deletions(-) --- base-commit: a32e14f8aef69b42826cf0998b068a43d486a9e9 change-id: 20241210-elf-b80ea3949c39 Best regards, -- Akihiko Odaki <akihiko.odaki@xxxxxxxxxx>
