selftests: cgroup: config fragments required

by Naresh Kamboju

selftest cgroup tests are getting skipped due to missing kernel config fragments. Please create the required config fragments "config" file. Our CI system merges these kernel config fragments and builds the kernel for testing. You may refer config files in other test directories.

Re: [PATCH v3 3/7] kunit: tests for stats_fs API

However could the tests also be built as a module (i.e. make CONFIG_STATS_FS_TEST a tristate variable)? To test this you'd need to specify CONFIG_KUNIT=m and CONFIG_STATS_FS_TEST=m, and testing would simply be a case of "modprobe"ing the stats fs module and collecting results in /sys/kernel/debug/kunit/<module_name> (rather than running kunit.py). Are you relying on unexported internals in the the tests that would prevent building them as a module? Thanks! Alan

This is `make install` ;). I personally do not need OOT build, but since it's in the code, I'd prefer either fix it or remove it, otherwise it's misleading.

Kunit get 0 tests when run defconfig in Debian9

by kernel test robot

Hi, all. I met a strange problem that kunit run 0 tests in Debian9. Env: ``` root@lkp-hsw-ep4 ~/linus# head /etc/os-release PRETTY_NAME="Debian GNU/Linux 9 (stretch)" NAME="Debian GNU/Linux" VERSION_ID="9" VERSION="9 (stretch)" ID=debian root@lkp-hsw-ep4 ~/linus# uname -r 5.6.0 ``` Reproduce: Just run `./tools/testing/kunit/kunit.py run --defconfig` ``` root@lkp-hsw-ep4 ~/linus# ./tools/testing/kunit/kunit.py run --defconfig [13:41:30] Building KUnit Kernel ...

[PATCH] selftests: powerpc: Add test for execute-disabled pkeys

Apart from read and write access, memory protection keys can also be used for restricting execute permission of pages on powerpc. This adds a test to verify if the feature works as expected.

OUTPUT and TEST_CUSTOM_PROGS

by Yauheni Kaliuta

Hi! lib.mk expects TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED and TEST_GEN_FILES to be in local directory and tries to handle out of tree build adding OUTPUT to it at the beginning. commit be16a244c199 ("selftests: lib.mk: add TEST_CUSTOM_PROGS to allow custom test run/install") adds TEST_CUSTOM_PROGS but it handles it differently. Should it add OUTPUT as well? -- WBR, Yauheni Kaliuta
