Testing & Fuzzing Micro-Conference at Linux Plumbers Conference 2021

by Guillaume Tucker

The Testing & Fuzzing Micro-Conference[1] at Linux Plumbers 2021 will remain open to new proposals for talks and discussion topics until the end of next week (Friday 10th Sept). Please feel free to submit yours with the "Submit new proposal" form on this page: https://linuxplumbersconf.org/event/11/abstracts/ The MC is currently scheduled for Wednesday 22nd. This is where the timetable will appear as submissions get accepted: https://linuxplumbersconf.org/event/11/sessions/110/#20210922 Last year's edition was very effective in spite of being fully online rather than in-person. Topics around testing were mentioned in many other tracks too, such as real-time and toolchains. See also the related KernelCI blog post with community notes[2]. We're looking forward to having an equally good virtual experience this time again. Best wishes, Guillaume [1] https://www.linuxplumbersconf.org/blog/2021/index.php/2021/07/09/testing-an… The Testing and Fuzzing microconference focuses on advancing the current state of testing of the Linux kernel. We aim to create connections between folks working on similar projects, and help individual projects make progress. We ask that any topic discussions will focus on issues/problems they are facing and possible alternatives to resolving them. The Microconference is open to all topics related to testing & fuzzing on Linux, not necessarily in the kernel space. Suggested topics: KernelCI: Extending coverage and improving user experience. Growing KCIDB, integrating more sources. Better sanitizers: KFENCE, improving KCSAN. Using Clang for better testing coverage. How to spread KUnit throughout the kernel? Testing in-kernel Rust code. MC leads: Sasha Levin <sashal(a)kernel.org> Guillaume Tucker <guillaume.tucker(a)collabora.com> [2] https://foundation.kernelci.org/blog/2020/09/23/kernelci-notes-from-plumber…

[PATCH v3 1/4] kunit: tool: Do not error on tests without test plans

by David Gow

The (K)TAP spec encourages test output to begin with a 'test plan': a count of the number of tests being run of the form: 1..n However, some test suites might not know the number of subtests in advance (for example, KUnit's parameterised tests use a generator function). In this case, it's not possible to print the test plan in advance. kunit_tool already parses test output which doesn't contain a plan, but reports an error. Since we want to use nested subtests with KUnit paramterised tests, remove this error.

[PATCH v3 0/5] test_hash.c: refactor into KUnit

by Isabella Basso

We refactored the lib/test_hash.c file into KUnit as part of the student group LKCAMP [1] introductory hackathon for kernel development. This test was pointed to our group by Daniel Latypov [2], so its full conversion into a pure KUnit test was our goal in this patch series, but we ran into many problems relating to it not being split as unit tests, which complicated matters a bit, as the reasoning behind the original tests is quite cryptic for those unfamiliar with hash implementations. Some interesting developments we'd like to highlight are: - In patch 1/5 we noticed that there was an unused define directive that could be removed. - In patch 4/5 we noticed how stringhash and hash tests are all under the lib/test_hash.c file, which might cause some confusion, and we also broke those kernel config entries up. Overall KUnit developments have been made in the other patches in this series: In patches 2/5, 3/5 and 5/5 we refactored the lib/test_hash.c file so as to make it more compatible with the KUnit style, whilst preserving the original idea of the maintainer who designed it (i.e. George Spelvin), which might be undesirable for unit tests, but we assume it is enough for a first patch. This is our first patch series so we hope our contributions are interesting and also hope to get some useful criticism from the community. :) Changes since v2: - Added comments on struct elements. - Removed unecessary __init bits from KUnit test functions. - Change KUnit's "EXPECT_FALSE"s for "EXPECT_EQ"s. Changes since v1: - Fixed compilation on parisc and m68k. - Fixed whitespace mistakes. - Renamed a few functions. - Refactored globals into struct for test function params, thus removing a patch. - Reworded some commit messages.
