From 3af2785c97622c0a64b266e18a06d735af822df9 Mon Sep 17 00:00:00 2001 From: Luis Machado Date: Thu, 5 Aug 2021 13:50:17 -0300 Subject: Add 3 new PAC-related ARM note types The following patch synchronizes includes/objdump/readelf with the Linux Kernel in terms of ARM regset notes. We're currently missing 3 of them: NT_ARM_PACA_KEYS NT_ARM_PACG_KEYS NT_ARM_PAC_ENABLED_KEYS We don't need GDB to bother with this at the moment, so this doesn't update bfd/elf.c. If needed, we can do it in the future. binutils/ * readelf.c (get_note_type): Handle new ARM PAC notes. include/elf/ * common.h (NT_ARM_PACA_KEYS, NT_ARM_PACG_KEYS) (NT_ARM_PAC_ENABLED_KEYS): New constants. --- include/elf/common.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'include') diff --git a/include/elf/common.h b/include/elf/common.h index 0d381f0..95ade89 100644 --- a/include/elf/common.h +++ b/include/elf/common.h @@ -672,9 +672,18 @@ /* note name must be "LINUX". */ #define NT_ARM_PAC_MASK 0x406 /* AArch pointer authentication code masks */ /* note name must be "LINUX". */ +#define NT_ARM_PACA_KEYS 0x407 /* ARM pointer authentication address + keys */ + /* note name must be "LINUX". */ +#define NT_ARM_PACG_KEYS 0x408 /* ARM pointer authentication generic + keys */ + /* note name must be "LINUX". */ #define NT_ARM_TAGGED_ADDR_CTRL 0x409 /* AArch64 tagged address control (prctl()) */ /* note name must be "LINUX". */ +#define NT_ARM_PAC_ENABLED_KEYS 0x40a /* AArch64 pointer authentication + enabled keys (prctl()) */ + /* note name must be "LINUX". */ #define NT_ARC_V2 0x600 /* ARC HS accumulator/extra registers. */ /* note name must be "LINUX". */ #define NT_RISCV_CSR 0x900 /* RISC-V Control and Status Registers */ -- cgit v1.1
