kprobes: use _do_fork() in samples to make them work again

2015-10-02T01:42:35Z

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.

kprobes: update jprobe_example.c for do_fork() change

2014-09-26T09:11:12Z

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. Signed-off-by: Michael Ellerman Acked-by: Masami Hiramatsu Signed-off-by: Jiri Kosina

SAMPLES: kprobe_example: Make it print something on MIPS.

2010-08-05T12:26:29Z

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.

Kprobes: move kprobe examples to samples/

2008-03-05T00:35:11Z

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.
