  • 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.

    Provide support to add an optional user defined callback to be run at
    function entry of a kretprobe'd function. Also modify the kprobe smoke
    tests to include an entry-handler during the kretprobe sanity test.

  • 9e367d859   jprobes: remove JPROBE_ENTRY() ... Browse Code »

    AFAICT now that jprobe.entry is a void *, JPROBE_ENTRY doesn't do anything
    useful - so remove it ..

    I've left a do-nothing version so that out-of-tree jprobes code will still
    compile without modifications.

  • bf8f6e5b3   Kprobes: The ON/OFF knob thru debugfs ... Browse Code »

    This patch provides a debugfs knob to turn kprobes on/off

    o A new file /debug/kprobes/enabled indicates if kprobes is enabled or
    not (default enabled)
    o Echoing 0 to this file will disarm all installed probes
    o Any new probe registration when disabled will register the probe but
    not arm it. A message will be printed out in such a case.
    o When a value 1 is echoed to the file, all probes (including ones
    registered in the intervening period) will be enabled
    o Unregistration will happen irrespective of whether probes are globally
    enabled or not.
    o Update Documentation/kprobes.txt to reflect these changes. While there
    also update the doc to make it current.

    We are also looking at providing sysrq key support to tie to the disabling
    feature provided by this patch.
