From mboxrd@z Thu Jan 1 00:00:00 1970 From: Hiraku Toyooka Subject: [PATCH v2 0/2] selftests/pstore: add pstore test script Date: Fri, 02 Oct 2015 20:46:37 +0900 Message-ID: <20151002114637.20957.61769.stgit@arietta> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Sender: linux-api-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-kernel-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Cc: Tony Luck , Kees Cook , linux-api-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, Anton Vorontsov , Shuah Khan , Mark Salyzyn , Colin Cross , Seiji Aguchi List-Id: linux-api@vger.kernel.org These scripts include test cases which check pstore behavior. This is useful to avoid regressions of pstore. Changes since v1: * Exit with 1 in pstore/Makefile when pstore_crash_test failed. * Create helper functions to make the tests much more readable. * Use /sys/module/pstore/parameters/backend to check pstore backend is registered. * Show content of /sys/module/.../backend and /proc/cmdline for debug * Give UUID to each execution of test script. * Write unique test string with UUID into pmsg. * Check only one test string pattern appears in pmsg after crash. * Check UUID written to pmsg matches across crash. * Don't touch panic_on_oops because it is not necessary for reboot on crash (v1: http://www.kernelhub.org/?msg=831044&p=2) I also confirmed that these scripts work fine with kdump reboot with kernel boot parameter 'crash_kexec_post_notifiers'. --- Hiraku Toyooka (2): selftests/pstore: add pstore test script for pre-reboot selftests/pstore: add pstore test scripts going with reboot tools/testing/selftests/Makefile | 4 + tools/testing/selftests/pstore/Makefile | 15 ++++ tools/testing/selftests/pstore/common_tests | 83 ++++++++++++++++++++ tools/testing/selftests/pstore/pstore_crash_test | 30 +++++++ .../selftests/pstore/pstore_post_reboot_tests | 77 +++++++++++++++++++ tools/testing/selftests/pstore/pstore_tests | 30 +++++++ 6 files changed, 239 insertions(+) create mode 100644 tools/testing/selftests/pstore/Makefile create mode 100755 tools/testing/selftests/pstore/common_tests create mode 100755 tools/testing/selftests/pstore/pstore_crash_test create mode 100755 tools/testing/selftests/pstore/pstore_post_reboot_tests create mode 100755 tools/testing/selftests/pstore/pstore_tests -- Hiraku Toyooka
