  • 54aea4542   kprobes: use _do_fork() in samples to make them work again ... Browse Code »

    Commit 3033f14ab78c ("clone: support passing tls argument via C rather
    than pt_regs magic") introduced _do_fork() that allowed to pass @tls
    parameter.

    The old do_fork() is defined only for architectures that are not ready
    to use this way and do not define HAVE_COPY_THREAD_TLS.

    Let's use _do_fork() in the kprobe examples to make them work again on
    all architectures.

  • e8ac6ea8a   kprobes: update jprobe_example.c for do_fork() change ... Browse Code »

    In commit e80d666 "flagday: kill pt_regs argument of do_fork()", the
    arguments to do_fork() changed.

    The example code in jprobe_example.c was not updated to match, so the
    arguments inside the jprobe handler do not match reality.

    Fix it by updating the arguments to match do_fork(). While we're at it
    use pr_info() for brevity, and print stack_start as well for interest.

  • 8a1492370   SAMPLES: kprobe_example: Make it print something on MIPS. ... Browse Code »

    This KProbes example is a little useless if it doesn't print anything.
    For MIPS print similar messages to those produced on x86 and PPC.

  • 804defea1   Kprobes: move kprobe examples to samples/ ... Browse Code »

    Move kprobes examples from Documentation/kprobes.txt to under samples/.
    Patch originally by Randy Dunlap.

    o Updated the patch to apply on 2.6.25-rc3
    o Modified examples code to build on multiple architectures. Currently,
    the kprobe and jprobe examples code works for x86 and powerpc
    o Cleaned up unneeded #includes
    o Cleaned up Kconfig per Sam Ravnborg's suggestions to fix build break
    on archs that don't have kretprobes
    o Implemented suggestions by Mathieu Desnoyers on CONFIG_KRETPROBES
    o Included Andrew Morton's cleanup based on x86-git
    o Modified kretprobe_example to act as a arch-agnostic module to
    determine routine execution times:
    Use 'modprobe kretprobe_example func=' to determine
    execution time of func_name in nanoseconds.
