[PATCH RFC v2 0/6] ARM64: Add kernel probes(Kprobes) support

by Sandeepa Prabhu

This patchset adds support for kernel probes(kprobes), jump probes(jprobes) and return probes(kretprobes) support for ARM64. Kprobes mechanism make use of software breakpoint and single stepping support available in ARM v8 kernel. This patchset make use of (and dependant upon) dynamic kernel patching feature published in patch series: https://lkml.org/lkml/2013/10/15/891 changes: v1 -> v2 1. Implemented review comments on v1 2. Debug montior hooks implementation is changed to use rwlocks instead of rcu and spinlock. 3. Enabled recursing in kprobes handler for kprobes re-enter support. 4. Re-split the patchset to seperate single-stepping, simulation and kretprobes features. 5. instruction simulation is made independent of 'struct kprobes' 6. Added 'Linaro Copyright' statements in new added files. 7. Used arm64 instead of aarch64 in file names and comments. Tested on ARM v8 fast model with sample modules from: samples/kprobes/ Sandeepa Prabhu (6): arm64: support single-step and breakpoint handler hooks arm64: Kprobes with single stepping support arm64: Kprobes instruction simulation support arm64: Add kernel return probes support(kretprobes) arm64: Enable kprobes support for arm64 platform kprobes: Add cases for arm and arm64 in sample module arch/arm64/Kconfig | 2 + arch/arm64/configs/defconfig | 20 +- arch/arm64/include/asm/debug-monitors.h | 21 + arch/arm64/include/asm/kprobes.h | 60 +++ arch/arm64/include/asm/probes.h | 50 +++ arch/arm64/include/asm/ptrace.h | 6 + arch/arm64/kernel/Makefile | 2 + arch/arm64/kernel/condn-helpers.c | 120 ++++++ arch/arm64/kernel/debug-monitors.c | 86 +++- arch/arm64/kernel/entry.S | 2 + arch/arm64/kernel/kprobes-arm64.c | 313 +++++++++++++++ arch/arm64/kernel/kprobes-arm64.h | 30 ++ arch/arm64/kernel/kprobes.c | 682 ++++++++++++++++++++++++++++++++ arch/arm64/kernel/kprobes.h | 30 ++ arch/arm64/kernel/probes-decode.h | 110 ++++++ arch/arm64/kernel/simulate-insn.c | 184 +++++++++ arch/arm64/kernel/simulate-insn.h | 33 ++ arch/arm64/kernel/vmlinux.lds.S | 1 + samples/kprobes/kprobe_example.c | 16 + 19 files changed, 1756 insertions(+), 12 deletions(-) create mode 100644 arch/arm64/include/asm/kprobes.h create mode 100644 arch/arm64/include/asm/probes.h create mode 100644 arch/arm64/kernel/condn-helpers.c create mode 100644 arch/arm64/kernel/kprobes-arm64.c create mode 100644 arch/arm64/kernel/kprobes-arm64.h create mode 100644 arch/arm64/kernel/kprobes.c create mode 100644 arch/arm64/kernel/kprobes.h create mode 100644 arch/arm64/kernel/probes-decode.h create mode 100644 arch/arm64/kernel/simulate-insn.c create mode 100644 arch/arm64/kernel/simulate-insn.h -- 1.8.1.2
