samples/jprobe: convert the printk to pr_info/pr_err

2016-08-04T12:50:07+00:00

We prefer to use the pr_* to print out the log now, this patch converts
the printk to pr_info.  In the error path, use the pr_err to replace the
printk.

kprobes: add the "tls" argument for j_do_fork

2016-05-21T00:58:30+00:00

Commit 3033f14ab78c ("clone: support passing tls argument via C rather
than pt_regs magic") added the tls argument for _do_fork().  This patch
adds the "tls" argument for j_do_fork to make it match _do_fork().

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

2015-10-02T01:42:35+00:00

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

2014-09-26T09:11:12+00:00

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.

Kprobes: move kprobe examples to samples/

2008-03-05T00:35:11+00:00

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.
