perf_event_tests's Introduction

The Perf Event Testsuite
  by Vince Weaver   <vincent.weaver _at_ maine.edu>


This series of test is meant to validate that the perf_event
subsystem is working.


QUICKSTART
~~~~~~~~~~
  1. run "make"
  2. run "./run_tests.sh"

  If a test fails you can run the individual test to get more info on
  why.

CROSS COMPILE
~~~~~~~~~~~~~

  1. make sure that the cross compiler toolchain is in PATH
  2. run "make CROSS_COMPILE=<compiler name>"

  e.g., "make CROSS_COMPILE=arm-linux-gnueabihf-"


LAYOUT
~~~~~~
There are various subdirectories:

   + crashes   -- these contain tests known to crash certain
                  kernel versions from userspace.
                  * USE CAUTION RUNNING THESE TESTS *

   + exploits  -- perf_event code that can cause some sort of security exploit

   + fuzzer    -- a fuzzer tool that tries to hit the extremes of
                  the perf_event interface and find bugs in the kernel

   + include   -- common include files

   + lib       -- common library code

   + papi      -- tests for the PAPI library.  Only compile/run
                  these if you have PAPI installed

   + perf_event_h -- an archive of perf_event.h files over the
                     history of the interface.  Useful when
                     figuring out when a feature was added

   + results   -- results of ./run_tests.sh across kernel versions

   + tests     -- all of the various tests live under here

   + tools     -- various perf_event related tools

perf_event_tests's Issues

tests/openmp/openmp_sample: Segmentation fault

lkp caught a "Segmentation fault" when running tests/openmp/openmp_sample since kernel commit:
f812fdeee ("signal: Add calculate_sigpending()")

root@lkp-hsw-ep4 /lkp/benchmarks/perf_event_tests# tests/openmp/openmp_sample
Testing OpenMP sample behavior
Note!!! Inherit only works if the event is created
before the fork happens!  OpenMP creates thread pools
so if you create the event after the thread pools hae been
created it may be too late and you won't get child events!

Segmentation fault

fuzzer calls parse_open_event with wrong pointer

In active_events.c 'pe' is a perf_event_attr, in fuzzer.c 'pe' is a pointer to perf_event_attr. parse_open_event is called with &pe both times. This is likely to crash or corrupt something, and my build warns about it. Judging from the code, fuzzer.c should call parse_open_event with ...,pe not ...,&pe).

ARM build breakage

Hi,

The following commit breaks building for ARM and AArch64.

commit d16cdafcae817fa27dc650fe1404ba1ba20247cb
Author: Vince Weaver
Date:   Thu Jul 10 16:45:38 2014 -0400

    tests: add support for reading the SAMPLE_REGS_USERS values

    was actually introduced in 3.7, running a bit behind.      

    values are screwy though, need to find out why.

how do I port this to android

hi,deater, I want to port this to android,but I do not know how to write the shellcode on android ,how do I port this to android.Can you help me to port this on android , thanks

After run perftool.py in Rhel8.1 with Avocado(version:77.0), it shows "CANCEL: gcc-g++ is needed for the test to be run", which makes the result FAIL

【Test Result】
After run perftool.py in Rhel8.1 with Avocado(version:77.0), it shows "CANCEL: gcc-g++ is needed for the test to be run", which makes the result FAIL. SOL-log is like below:

(1/1) perftool.py:Perftool.test: CANCEL: gcc-g++ is needed for the test to be run (9.69 s)
RESULTS : PASS 0 | ERROR 0 | FAIL 0 | SKIP 0 | WARN 0 | INTERRUPT 0 | CANCEL 1

However, we can't install "gcc-g++" in Rhel8.1 so far. Please check if Rhel8.1 supports "gcc-g++" and the test of perftool.py.

【Expect Result】
After run perftool.py, it should show PASS.

【Test Steps】
Run perftool.py via cmd "avocado run perftool.py"

【Configuration】

perf_event_tests: branches and non-existent are failing for aarch64

Hi,

I am using Hikey (ARM64) target.

When I execute perf_event_tests below are failing:

[1]. perf "branches" test failing with below error:
{{{

[2]. perf "non-existent" failing with below error:

Could you please share your comments whether this supports AArch64 targets or not. and How to resolve above issues.

Thanks,

all above results are tested under root.

are those failures possible related to hardware?

    Testing if minimized rdpmc papi-multi-attach works...        FAILED

there are two different cases comparing to your uploaded results (results/haswell/haswell-4.13-rc0 )
For the EACCES, it can be passed if i run it with a normal user
For the EPERM, it always failed under both root and normal user

want to know, is EACCES required under root, what's user when you run thoes cases
and any idea about EPERM?
