Running kunit tests on platform devices

by Ramon Fried

Hi. I implemented a test suite that checks a platform driver, that's the only way I can test interrupts behavior in the code. Because it's a platform, I can't use kunit_test_suite(), so I call __kunit_test_suites_init() as part of the platform driver probe function. This works fine but has the following problems. "TAP version 14" string is not printed and it's impossible to parse the results using the script. In addition, the suite is not displayed in /sys/kernel/debug/kunit. It would be my pleasure to provide a patch that fixes this, I just wanted to make sure that my testing strategy makes sense. Thanks, Ramon

[PATCH v4 0/4] Introduce security_create_user_ns()

by Frederick Lawler

While creating a LSM BPF MAC policy to block user namespace creation, we used the LSM cred_prepare hook because that is the closest hook to prevent a call to create_user_ns(). The calls look something like this: cred = prepare_creds() security_prepare_creds() call_int_hook(cred_prepare, ... if (cred) create_user_ns(cred) We noticed that error codes were not propagated from this hook and introduced a patch [1] to propagate those errors. The discussion notes that security_prepare_creds() is not appropriate for MAC policies, and instead the hook is meant for LSM authors to prepare credentials for mutation. [2] Ultimately, we concluded that a better course of action is to introduce a new security hook for LSM authors. [3] This patch set first introduces a new security_create_user_ns() function and userns_create LSM hook, then marks the hook as sleepable in BPF.

[PATCH] selftests/vm: enable running select groups of tests

by Joel Savitz

Add the ability to run one or more groups of vm tests (specified by the environment variable TEST_ITEMS). Preserve existing default behavior of running all tests when TEST_ITEMS is empty or "default". Documentation of test groups is included in the patch as follows: # ./run_vmtests.sh [ -h || --help ] usage: ./tools/testing/selftests/vm/run_vmtests.sh [ -h ] -h: display this message The default behavior is to run all tests. Alternatively, specific groups tests can be run by defining the TEST_ITEMS shell variable with a space-separated string of one or more of the following: - mmap tests for mmap(2) - gup_test tests for gup using gup_test interface - userfaultfd tests for userfaultfd(2) - compaction a test for the patch "Allow compaction of unevictable pages" - mlock tests for mlock(2) - mremap tests for mremap(2) - hugevm tests for very large virtual address space - vmalloc vmalloc smoke tests - hmm hmm smoke tests - madv_populate test memadvise(2) MADV_POPULATE_{READ,WRITE} options - memfd_secret test memfd_secret(2) - process_mrelease test process_mrelease(2) - ksm ksm tests that do not require >=2 NUMA nodes - ksm_numa ksm tests that require >=2 NUMA nodes example: TEST_ITEMS="hmm mmap ksm" ./run_vmtests.sh Signed-off-by: Joel Savitz <jsavitz(a)redhat.com> --- tools/testing/selftests/vm/run_vmtests.sh | 224 +++++++++++++++------- 1 file changed, 150 insertions(+), 74 deletions(-) diff --git a/tools/testing/selftests/vm/run_vmtests.sh b/tools/testing/selftests/vm/run_vmtests.sh index 41fce8bea929..d31fc66205f8 100755 --- a/tools/testing/selftests/vm/run_vmtests.sh +++ b/tools/testing/selftests/vm/run_vmtests.sh @@ -1,22 +1,74 @@ #!/bin/bash # SPDX-License-Identifier: GPL-2.0 -#please run as root +# Please run as root # Kselftest framework requirement - SKIP code is 4. ksft_skip=4 mnt=./huge exitcode=0 - -#get huge pagesize and freepages from /proc/meminfo -while read -r name size unit; do - if [ "$name" = "HugePages_Free:" ]; then - freepgs="$size" - fi - if [ "$name" = "Hugepagesize:" ]; then - hpgsize_KB="$size" +nr_tests_ran=0 + +if [ ${1:-0} == "-h" ] || [ ${1:-0} == "--help" ] +then + cat <<EOF +usage: ${BASH_SOURCE[0]:-$0} [ -h ] + -h: display this message + +The default behavior is to run all tests. + +Alternatively, specific groups tests can be run by defining +the TEST_ITEMS shell variable with a space-separated string +of one or more of the following: +- mmap + tests for mmap(2) +- gup_test + tests for gup using gup_test interface +- userfaultfd + tests for userfaultfd(2) +- compaction + a test for the patch "Allow compaction of unevictable pages" +- mlock + tests for mlock(2) +- mremap + tests for mremap(2) +- hugevm + tests for very large virtual address space +- vmalloc + vmalloc smoke tests +- hmm + hmm smoke tests +- madv_populate + test memadvise(2) MADV_POPULATE_{READ,WRITE} options +- memfd_secret + test memfd_secret(2) +- process_mrelease + test process_mrelease(2) +- ksm + ksm tests that do not require >=2 NUMA nodes +- ksm_numa + ksm tests that require >=2 NUMA nodes +example: TEST_ITEMS="hmm mmap ksm" ./run_vmtests.sh +EOF + exit 0 +fi # $1 == -h || $1 == --help + +# default behavior: run all tests +TEST_ITEMS=${TEST_ITEMS:-default} + +echo "Selected test items: ${TEST_ITEMS}" + +test_selected() { + if [ "$TEST_ITEMS" == "default" ]; then + # If no TEST_ITEMS are specified, run all tests + return 0 fi -done < /proc/meminfo + echo ${TEST_ITEMS} | grep ${1} 2>&1 >/dev/null + return ${?} +} + +# Hugepage setup only needed for hugetlb tests +if test_selected "hugetlb"; then # Simple hugetlbfs tests have a hardcoded minimum requirement of # huge pages totaling 256MB (262144KB) in size.

OpenSSL 3.0 deprecates some of the functions used in the SGX selftests, causing build errors on new distros.

[PATCH AUTOSEL 5.18 44/56] selftests/kprobe: Do not test for GRP/ without event failures

by Sasha Levin

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> [ Upstream commit f5eab65ff2b76449286d18efc7fee3e0b72f7d9b ] A new feature is added where kprobes (and other probes) do not need to explicitly state the event name when creating a probe. The event name will come from what is being attached. That is: # echo 'p:foo/ vfs_read' > kprobe_events Will no longer error, but instead create an event: # cat kprobe_events p:foo/p_vfs_read_0 vfs_read This should not be tested as an error case anymore. Remove it from the selftest as now this feature "breaks" the selftest as it no longer fails as expected.
