From: "David A. Long" <dave.l...@linaro.org>
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 v4:
1) The dependency on kprobe.h is now correctly fixed.
2) A few changes to correctly support bigendian.
3) Remove the opcode address arg from the emulate and simulate functions
and just get the address from the pt_regs structure instead.
This patchset is based on v3.13-rc4.
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
actions
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
