kprobes: Disable the jprobes test code

2017-10-20T09:02:54Z

Disable jprobes test code because jprobes are deprecated. This code will be completely removed when the jprobe code is removed.

kprobes: Improve smoke test to check preemptibility

2017-09-28T07:23:03Z

Add preemptible check to each handler. Handlers are called with non-preemtible, which is guaranteed by Documentation/kprobes.txt.

kernel/test_kprobes.c: use current logging functions

2014-08-08T22:57:18Z

- Add pr_fmt - Coalesce formats - Use current pr_foo() functions instead of printk - Remove unnecessary "failed" display (already in log level).

kernel/: rename random32() to prandom_u32()

2013-04-30T01:28:42Z

Use preferable function name which implies using a pseudo-random number generator. Signed-off-by: Akinobu Mita Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kprobes: Fix selftest to clear flags field for reusing probes

2010-10-14T06:55:27Z

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.

kprobes: add tests for register_kprobes

Add testcases for *probe batch registration (register_kprobes) to kprobes sanity tests. Signed-off-by: Masami Hiramatsu Acked-by: Ananth N Mavinakayanahalli Cc: Jim Keniston Cc: David Miller Cc: Anil S Keshavamurthy Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

kprobes: indirectly call kprobe_target

2009-01-06T23:59:20Z

Call kprobe_target indirectly. This prevents gcc to unroll a noinline function in caller function.

kprobes: kretprobe user entry-handler

2008-02-06T18:41:11Z

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.

x86: kprobes: add kprobes smoke tests that run on boot

2008-01-30T12:32:53Z

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.
