Unit test for following has been done so far and they have been found working 1. Normal instruction, which can be probed like sub, ldr, add etc. 2. Instructions which can be simulated like ret. 3. uretprobe [1]https://lkml.org/lkml/2014/11/18/33 Pratyush Anand (8): ARM64: Move BRK opcodes defines from kprobes.h to insn.h ARM64: Refactor kprobes-arm64 Kernel/uprobe: Define arch_uprobe_exception_notify as __weak ARM64: Add instruction_pointer_set function ARM64: Re-factor flush_ptrace_access ARM64: Handle TRAP_HWBRKPT for user mode as well ARM64: Handle TRAP_BRKPT for user mode as well ARM64: Add uprobe support arch/arm/kernel/uprobes.c | 6 - arch/arm64/Kconfig | 3 + arch/arm64/include/asm/insn.h | 8 + arch/arm64/include/asm/probes.h | 26 ++- arch/arm64/include/asm/ptrace.h | 7 + arch/arm64/include/asm/thread_info.h | 5 +- arch/arm64/include/asm/uprobes.h | 43 ++++ arch/arm64/kernel/Makefile | 5 +- arch/arm64/kernel/debug-monitors.c | 14 +- arch/arm64/kernel/kprobes.c | 11 +- arch/arm64/kernel/kprobes.h | 7 +- .../kernel/{kprobes-arm64.c => probes-arm64.c} | 84 +++---- .../kernel/{kprobes-arm64.h => probes-arm64.h} | 17 +- arch/arm64/kernel/probes-condn-check.c | 2 +- arch/arm64/kernel/probes-decode.h | 4 +- arch/arm64/kernel/signal.c | 4 +- arch/arm64/kernel/uprobes.c | 255 +++++++++++++++++++++ arch/arm64/mm/flush.c | 30 ++- kernel/events/uprobes.c | 18 ++ 19 files changed, 445 insertions(+), 104 deletions(-) create mode 100644 arch/arm64/include/asm/uprobes.h rename arch/arm64/kernel/{kprobes-arm64.c => probes-arm64.c} (79%) rename arch/arm64/kernel/{kprobes-arm64.h => probes-arm64.h} (60%) create mode 100644 arch/arm64/kernel/uprobes.c -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
