March 2020 - Linux-kselftest-mirror

by Dmitry Vyukov

Hi Shuah, We discussed collecting and uploading all syzkaller reproducers somewhere. You wanted to see how they look. I've uploaded all current reproducers here: https://github.com/dvyukov/syzkaller-repros Minimalistic build/run scripts are included. +some testing mailing lists too as this can be used as a test suite If you have any potential uses for this, you are welcome to use it. But then we probably need to find some more official and shared place for them than my private github. The test programs can also be bulk updated if necessary, because all of this is auto-generated. Thanks

[PATCH] kunit/kunit_kernel: Rebuild .config if .kunitconfig is modified

by sj38.park＠gmail.com

From: SeongJae Park <sjpark(a)amazon.de> Deletions of configs in the '.kunitconfig' is not applied because kunit rebuilds '.config' only if the '.config' is not a subset of the '.kunitconfig'. To allow the deletions to applied, this commit modifies the '.config' rebuild condition to addtionally check the modified times of those files.

[RFC PATCH kunit-next 0/2] kunit: extend kunit resources API

by Alan Maguire

A recent RFC patch set [1] suggests some additional functionality may be needed around kunit resources. It seems to require 1. support for resources without allocation 2. support for lookup of such resources 3. support for access to resources across multiple kernel threads The proposed changes here are designed to address these needs. The idea is we first generalize the API to support adding resources with static data; then from there we support named resources. The latter support is needed because if we are in a different thread context and only have the "struct kunit *" to work with, we need a way to identify a resource in lookup. [1] https://lkml.org/lkml/2020/2/26/1286 Alan Maguire (2): kunit: generalize kunit_resource API beyond allocated resources kunit: add support for named resources include/kunit/test.h | 145 ++++++++++++++++++++++------ lib/kunit/kunit-test.c | 103 ++++++++++++++++---- lib/kunit/string-stream.c | 14 ++- lib/kunit/test.c | 234 +++++++++++++++++++++++++++++++++------------- 4 files changed, 375 insertions(+), 121 deletions(-) -- 1.8.3.1

[PATCH v6 kunit-next 0/4] kunit: add debugfs representation to show results

by Alan Maguire

When kunit tests are run on native (i.e. non-UML) environments, the results of test execution are often intermixed with dmesg output. This patch series attempts to solve this by providing a debugfs representation of the results of the last test run, available as /sys/kernel/debug/kunit/<testsuite>/results Changes since v5: - replaced undefined behaviour use of snprintf(buf, ..., buf) in kunit_log() with a function to append string to existing log (Frank, patch 1) - added clarification on log size limitations to documentation (Frank, patch 4) Changes since v4: - added suite-level log expectations to kunit log test (Brendan, patch 2) - added log expectations (of it being NULL) for case where CONFIG_KUNIT_DEBUGFS=n to kunit log test (patch 2) - added patch 3 which replaces subtest tab indentation with 4 space indentation as per TAP 14 spec (Frank, patch 3) Changes since v3: - added CONFIG_KUNIT_DEBUGFS to support conditional compilation of debugfs representation, including string logging (Frank, patch 1) - removed unneeded NULL check for test_case in kunit_suite_for_each_test_case() (Frank, patch 1) - added kunit log test to verify logging multiple strings works (Frank, patch 2) - rephrased description of results file (Frank, patch 3) Changes since v2: - updated kunit_status2str() to kunit_status_to_string() and made it static inline in include/kunit/test.h (Brendan) - added log string to struct kunit_suite and kunit_case, with log pointer in struct kunit pointing at the case log. This allows us to collect kunit_[err|info|warning]() messages at the same time as we printk() them. This solves for the most part the sharing of log messages between test execution and debugfs since we just print the suite log (which contains the test suite preamble) and the individual test logs. The only exception is the suite-level status, which we cannot store in the suite log as it would mean we'd print the suite and its status prior to the suite's results. (Brendan, patch 1) - dropped debugfs-based kunit run patch for now so as not to cause problems with tests currently under development (Brendan) - fixed doc issues with code block (Brendan, patch 3) Changes since v1: - trimmed unneeded include files in lib/kunit/debugfs.c (Greg) - renamed global debugfs functions to be prefixed with kunit_ (Greg) - removed error checking for debugfs operations (Greg) Alan Maguire (4): kunit: add debugfs /sys/kernel/debug/kunit/<suite>/results display kunit: add log test kunit: subtests should be indented 4 spaces according to TAP kunit: update documentation to describe debugfs representation Documentation/dev-tools/kunit/usage.rst | 14 +++ include/kunit/test.h | 59 +++++++++++-- lib/kunit/Kconfig | 8 ++ lib/kunit/Makefile | 4 + lib/kunit/assert.c | 79 ++++++++--------- lib/kunit/debugfs.c | 116 +++++++++++++++++++++++++ lib/kunit/debugfs.h | 30 +++++++ lib/kunit/kunit-test.c | 45 +++++++++- lib/kunit/test.c | 147 +++++++++++++++++++++++++------- 9 files changed, 421 insertions(+), 81 deletions(-) create mode 100644 lib/kunit/debugfs.c create mode 100644 lib/kunit/debugfs.h -- 1.8.3.1

[RFC PATCH kunit-next] kunit: kunit_tool: Separate out config/build/exec/parse

by David Gow

Add new subcommands to kunit.py to allow stages of the existing 'run' subcommand to be run independently: - 'config': Verifies that .config is a subset of .kunitconfig - 'build': Compiles a UML kernel for KUnit - 'exec': Runs the kernel, and outputs the test results. - 'parse': Parses test results from a file or stdin Most of these are not hugely useful by themselves yet, and there's room for plenty of bikeshedding on the names, but this hopefully can form a foundation for future improvements. Signed-off-by: David Gow <davidgow(a)google.com> --- As was briefly disccussed in [1], this change is part of a "separation of concerns" in kunit_tool. This should make it easier to integrate kunit_tool into other setups. Of particular intrest is probably 'kunit.py parse', which should allow KUnit results to be parsed from other sources, such as after loading a module, or from a non-UML kernel, or from debugfs when that's supported[2].

[PATCH V1 00/13] Miscellaneous fixes for resctrl selftests

by Sai Praneeth Prakhya

This patch set has several miscellaneous fixes to resctrl selftest tool. Some fixes are minor in nature while other are major fixes. The minor fixes are 1. Typos, comment format 2. Fix MBA feature detection 3. Fix a bug while selecting sibling cpu 4. Remove unnecessary use of variable arguments 5. Change MBM/MBA results reporting format from absolute values to percentage The major fixes are changing CAT and CQM test cases. CAT test wasn't testing CAT as it isn't using the cache it's allocated, hence, change the test case to test noisy neighbor use case. CAT guarantees a user specified amount of cache for a process or a group of processes, hence test this use case. The updated test case checks if critical process is impacted by noisy neighbor or not. If it's impacted the test fails. The present CQM test assumes that all the allocated memory (size less than LLC size) for a process will fit into cache and there won't be any overlappings. While this is mostly true, it cannot be *always* true by the nature of how cache works i.e. two addresses could index into same cache line. Hence, change CQM test such that it now uses CAT. Allocate a specific amount of cache using CAT and check if CQM reports more than what CAT has allocated.

[PATCH] selftests/seccomp: Adjust test fixture counts

by Kees Cook

The seccomp selftest reported the wrong test counts since it was using slightly the wrong API for defining text fixtures. Adjust the API usage.
