2014-08-08kernel/test_kprobes.c: use current logging functionsFabian Frederick
- Add pr_fmt - Coalesce formats - Use current pr_foo() functions instead of printk - Remove unnecessary "failed" display (already in log level).

2013-04-29kernel/: rename random32() to prandom_u32()Akinobu Mita
Use preferable function name which implies using a pseudo-random number generator. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2010-10-14kprobes: Fix selftest to clear flags field for reusing probesMasami Hiramatsu
Fix selftest to clear flags field for reusing probes because the flags field can be modified by Kprobes. This also set NULL to kprobe.addr instead of 0.

2009-01-06kprobes: indirectly call kprobe_targetMasami Hiramatsu
Call kprobe_target indirectly. This prevents gcc to unroll a noinline function in caller function.

2008-02-06kprobes: kretprobe user entry-handlerAbhishek Sagar
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.

2008-01-30x86: kprobes: add kprobes smoke tests that run on bootAnanth N Mavinakayanahalli
Here is a quick and naive smoke test for kprobes. This is intended to just verify if some unrelated change broke the *probes subsystem. It is self contained, architecture agnostic and isn't of any great use by itself. This needs to be built in the kernel and runs a basic set of tests to verify if kprobes, jprobes and kretprobes run fine on the kernel. In case of an error, it'll print out a message with a "BUG" prefix. This is a start; we intend to add more tests to this bucket over time. Thanks to Jim Keniston and Masami Hiramatsu for comments and suggestions. Tested on x86 (32/64) and powerpc.
