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 v2 0/2] tracing/kselftest: histogram trigger expression tests

by Kalesh Singh

This series adds kselftest for histogram trigger expressions and is dependent on the series at [1] and can be applied on top of those after dropping the patch 7 in [1]. This version drops the changes to reset_trigger_file().

[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.

[RFC v6 net-next 0/6] Add RTNL interface for SyncE

by Maciej Machnikowski

Synchronous Ethernet networks use a physical layer clock to syntonize the frequency across different network elements. Basic SyncE node defined in the ITU-T G.8264 consist of an Ethernet Equipment Clock (EEC) and have the ability to recover synchronization from the synchronization inputs - either traffic interfaces or external frequency sources. The EEC can synchronize its frequency (syntonize) to any of those sources. It is also able to select synchronization source through priority tables and synchronization status messaging. It also provides neccessary filtering and holdover capabilities This patch series introduces basic interface for reading the Ethernet Equipment Clock (EEC) state on a SyncE capable device. This state gives information about the source of the syntonization signal (ether my port, or any external one) and the state of EEC. This interface is required\ to implement Synchronization Status Messaging on upper layers. v2: - removed whitespace changes - fix issues reported by test robot v3: - Changed naming from SyncE to EEC - Clarify cover letter and commit message for patch 1 v4: - Removed sync_source and pin_idx info - Changed one structure to attributes - Added EEC_SRC_PORT flag to indicate that the EEC is synchronized to the recovered clock of a port that returns the state v5: - add EEC source as an optiona attribute - implement support for recovered clocks - align states returned by EEC to ITU-T G.781 v6: - fix EEC clock state reporting - add documentation - fix descriptions in code comments Maciej Machnikowski (6): ice: add support detecting features based on netlist rtnetlink: Add new RTM_GETEECSTATE message to get SyncE status ice: add support for reading SyncE DPLL state rtnetlink: Add support for SyncE recovered clock configuration ice: add support for SyncE recovered clocks docs: net: Add description of SyncE interfaces Documentation/networking/synce.rst | 88 ++++++ drivers/net/ethernet/intel/ice/ice.h | 7 + .../net/ethernet/intel/ice/ice_adminq_cmd.h | 94 ++++++- drivers/net/ethernet/intel/ice/ice_common.c | 175 ++++++++++++ drivers/net/ethernet/intel/ice/ice_common.h | 17 +- drivers/net/ethernet/intel/ice/ice_devids.h | 3 + drivers/net/ethernet/intel/ice/ice_lib.c | 6 +- drivers/net/ethernet/intel/ice/ice_main.c | 138 ++++++++++ drivers/net/ethernet/intel/ice/ice_ptp.c | 34 +++ drivers/net/ethernet/intel/ice/ice_ptp_hw.c | 98 +++++++ drivers/net/ethernet/intel/ice/ice_ptp_hw.h | 25 ++ drivers/net/ethernet/intel/ice/ice_type.h | 1 + include/linux/netdevice.h | 33 +++ include/uapi/linux/if_link.h | 57 ++++ include/uapi/linux/rtnetlink.h | 10 + net/core/rtnetlink.c | 253 ++++++++++++++++++ security/selinux/nlmsgtab.c | 6 +- 17 files changed, 1041 insertions(+), 4 deletions(-) create mode 100644 Documentation/networking/synce.rst -- 2.26.3
