Long" This patch series adds basic uprobes support to ARM. It is based on patches developed earlier by Rabin Vincent. That approach of adding hooks into the kprobes instruction parsing code was not well received. This approach separates the ARM instruction parsing code in kprobes out into a separate set of functions which can be used by both kprobes and uprobes. Both kprobes and uprobes then provide their own semantic action tables to process the results of the parsing. The following are noteworthy changes made for v5: 1) Created new decode_action type, instead of adding to the decode_item union. 2) Hardcoded the action array sizes so any (erroneous) partial static initialization will still leave an array of the correct size. 3) Remove redundant defines for in_it_block and current_cond. 4) Moved some changes between patches to group them more logically. 5) Added missing copyright headers to a couple new files. 6) Removed unnecessary checking before modifying the instruction in decode_regs in arch/arm/kernel/probes.c. 7) Fixed missing handling of abort/traps during XOL processing. 8) Removed unused local variable in arch_uprobe_skip_sstep in arch/arm/kernel/uprobes.c 9) Added missing "=" in static array initialization. 10) Updated some descriptive comments to describe new behavior. 11) Patches are now against v3.13-rc8. David A. Long (15): uprobes: allow ignoring of probe hits ARM: move shared uprobe/kprobe definitions into new include file ARM: Move generic arm instruction parsing code to new files for sharing between features ARM: move generic thumb instruction parsing code to new files for use by other feature ARM: use a function table for determining instruction interpreter action ARM: Remove use of struct kprobe from generic probes code ARM: Use new opcode type in ARM kprobes/uprobes code ARM: Make the kprobes condition_check symbol names more generic ARM: Change more ARM kprobes symbol names to something more ARM: Rename the shared kprobes/uprobe return value enum ARM: Change the remaining shared kprobes/uprobes symbols to something generic ARM: Add an emulate flag to the kprobes/uprobes instruction decode functions ARM: Make arch_specific_insn a define for new arch_probes_insn structure ARM: add uprobes support ARM: Remove uprobes dependency on kprobes Jon Medhurst (Tixy) (1): ARM: Disable jprobes test when built into thumb-mode kernel arch/arm/Kconfig | 3 + arch/arm/include/asm/kprobes.h | 15 +- arch/arm/include/asm/probes.h | 43 + arch/arm/include/asm/ptrace.h | 6 + arch/arm/include/asm/thread_info.h | 5 +- arch/arm/include/asm/uprobes.h | 45 + arch/arm/kernel/Makefile | 7 +- arch/arm/kernel/kprobes-arm.c | 804 ++------------ arch/arm/kernel/kprobes-common.c | 468 +------- arch/arm/kernel/kprobes-test.c | 18 +- arch/arm/kernel/kprobes-thumb.c | 1142 +++----------------- arch/arm/kernel/kprobes.c | 23 +- arch/arm/kernel/kprobes.h | 400 +------ arch/arm/kernel/{kprobes-arm.c => probes-arm.c} | 441 ++------ arch/arm/kernel/probes-arm.h | 73 ++ .../arm/kernel/{kprobes-thumb.c => probes-thumb.c} | 770 ++----------- arch/arm/kernel/probes-thumb.h | 97 ++ arch/arm/kernel/{kprobes-common.c => probes.c} | 209 +--- arch/arm/kernel/{kprobes.h => probes.h} | 125 +-- arch/arm/kernel/signal.c | 4 + arch/arm/kernel/uprobes-arm.c | 231 ++++ arch/arm/kernel/uprobes.c | 208 ++++ arch/arm/kernel/uprobes.h | 35 + include/linux/uprobes.h | 1 + kernel/events/uprobes.c | 9 + 25 files changed, 1342 insertions(+), 3840 deletions(-) create mode 100644 arch/arm/include/asm/probes.h create mode 100644 arch/arm/include/asm/uprobes.h copy arch/arm/kernel/{kprobes-arm.c => probes-arm.c} (64%) create mode 100644 arch/arm/kernel/probes-arm.h copy arch/arm/kernel/{kprobes-thumb.c => probes-thumb.c} (56%) create mode 100644 arch/arm/kernel/probes-thumb.h copy arch/arm/kernel/{kprobes-common.c => probes.c} (67%) copy arch/arm/kernel/{kprobes.h => probes.h} (80%) create mode 100644 arch/arm/kernel/uprobes-arm.c create mode 100644 arch/arm/kernel/uprobes.c create mode 100644 arch/arm/kernel/uprobes.h -- 1.8.1.2 -- 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/
