    Hide CONFIG_OPTPROBES and set if the arch supports optimized
    kprobes (IOW, HAVE_OPTPROBES=y), since this option doesn't
    change the major behavior of kprobes, and workarounds for minor
    changes are documented.

  • 156f5a780   debugfs: Fix terminology inconsistency of dir name to mount debugfs filesystem. ... Browse Code »

    Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/"
    directory name to mount debugfs filesystem for ftrace according to
    ./Documentation/tracers/ftrace.txt file.

    And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is
    existed in kernel source like ftrace, DRM, Wireless, Documentation,
    Network[sky2]files to mount debugfs filesystem.

    debugfs means debug filesystem for debugging easy to use by greg kroah
    hartman. "/sys/kernel/debug/" name is suitable as directory name
    of debugfs filesystem.
    - debugfs related reference: http://lwn.net/Articles/334546/

    Fix inconsistency of directory name to mount debugfs filesystem.

    * From Steven Rostedt
    - find_debugfs() and tracing_files() in this patch.

  • de5bd88d5   kprobes: support per-kprobe disabling ... Browse Code »

    Add disable_kprobe() and enable_kprobe() to disable/enable kprobes
    temporarily.

    disable_kprobe() asynchronously disables probe handlers of specified
    kprobe. So, after calling it, some handlers can be called at a while.
    enable_kprobe() enables specified kprobe.

    aggr_pre_handler and aggr_post_handler check disabled probes. On the
    other hand aggr_break_handler and aggr_fault_handler don't check it
    because these handlers will be called while executing pre or post handlers
    and usually those help error handling.

  • e8386a0cb   kprobes: support probing module __exit function ... Browse Code »

    Allows kprobes to probe __exit routine. This adds flags member to struct
    kprobe. When module is freed(kprobes hooks module_notifier to get this
    event), kprobes which probe the functions in that module are set to "Gone"
    flag to the flags member. These "Gone" probes are never be enabled.
    Users can check the GONE flag through debugfs.

    This also removes mod_refcounted, because we couldn't free a module if
    kprobe incremented the refcount of that module.

  • 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.

    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.
