[PATCH v6 00/11] Add arm64/signal initial kselftest support

by Cristian Marussi

Hi this patchset aims to add the initial arch-specific arm64 support to kselftest starting with signals-related test-cases. This series is based on arm64/for-next/core [1]: commit 9ce1263033cd ("selftests, arm64: add a selftest for passing tagged pointers to kernel") A common internal test-case layout is proposed for signal tests and it is wired-up to the toplevel kselftest Makefile, so that it should be possible at the end to run it on an arm64 target in the usual way with KSFT. ~/linux# make TARGETS=arm64 kselftest New KSFT arm64 testcases live inside tools/testing/selftests/arm64 grouped by family inside subdirectories: arm64/signal is the first family proposed with this series. This series converts also to this subdirectory scheme the pre-existing (already queued on arm64/for-next/core) KSFT arm64 tags tests, moving them into arm64/tags. Thanks Cristian [1] git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git for-next/core Notes: ----- - further details in the included READMEs - more tests still to be written (current strategy is going through the related Kernel signal-handling code and write a test for each possible and sensible code-path) A few ideas for more TODO testcases: - fake_sigreturn_unmapped_sp: SP into unmapped addrs - fake_sigreturn_kernelspace_sp: SP into kernel addrs - fake_sigreturn_sve_bad_extra_context: SVE extra context badly formed - fake_sigreturn_misaligned_sp_4: misaligned SP by 4 (i.e., __alignof__(struct _aarch64_ctx)) - fake_sigreturn_misaligned_sp_8: misaligned SP by 8 (i.e., sizeof(struct _aarch64_ctx)) - fake_sigreturn_bad_size_non_aligned: a size that doesn't overflow __reserved[], but is not a multiple of 16 - fake_sigreturn_bad_size_tiny: a size that is less than 16 - fake_sigreturn_bad_size_overflow_tiny: a size that does overflow __reserved[], but by less than 16 bytes? - mangle_sve_invalid_extra_context: SVE extra_context invalid - SVE signal testcases and special handling will be part of an additional patch still to be released - KSFT arm64 tags test patch https://lore.kernel.org/linux-arm-kernel/c1e6aad230658bc175b42d92daeff2e300… is relocated into its own directory under tools/testing/selftests/arm64/tags Changes: -------- v5-->v6: -

[PATCH] Documentation: kunit: Fix verification command

by SeongJae Park

kunit wrapper script ('kunit.py') receives a sub-command (only 'run' for now) as its argument. If no sub-command is given, it prints help message and just quit. However, an example command in the kunit documentation for a verification of kunit is missing the sub-command. This commit fixes the example.

[PATCH v18 00/19] kunit: introduce KUnit, the Linux kernel unit testing framework

by Brendan Higgins

## TL;DR This revision addresses comments from Linus[1] and Randy[2], by moving top level `kunit/` directory to `lib/kunit/` and likewise moves top level Kconfig entry under lib/Kconfig.debug, so the KUnit submenu now shows up under the "Kernel Hacking" menu. As a consequence of this, I rewrote patch 06/18 (kbuild: enable building KUnit) - now 06/19 (lib: enable building KUnit in lib/), and now needs to be re-acked/reviewed. ## Background This patch set proposes KUnit, a lightweight unit testing and mocking framework for the Linux kernel. Unlike Autotest and kselftest, KUnit is a true unit testing framework; it does not require installing the kernel on a test machine or in a VM (however, KUnit still allows you to run tests on test machines or in VMs if you want[3]) and does not require tests to be written in userspace running on a host kernel. Additionally, KUnit is fast: From invocation to completion KUnit can run several dozen tests in about a second. Currently, the entire KUnit test suite for KUnit runs in under a second from the initial invocation (build time excluded). KUnit is heavily inspired by JUnit, Python's unittest.mock, and Googletest/Googlemock for C++. KUnit provides facilities for defining unit test cases, grouping related test cases into test suites, providing common infrastructure for running tests, mocking, spying, and much more. ### What's so special about unit testing? A unit test is supposed to test a single unit of code in isolation, hence the name. There should be no dependencies outside the control of the test; this means no external dependencies, which makes tests orders of magnitudes faster. Likewise, since there are no external dependencies, there are no hoops to jump through to run the tests. Additionally, this makes unit tests deterministic: a failing unit test always indicates a problem. Finally, because unit tests necessarily have finer granularity, they are able to test all code paths easily solving the classic problem of difficulty in exercising error handling code. ### Is KUnit trying to replace other testing frameworks for the kernel? No. Most existing tests for the Linux kernel are end-to-end tests, which have their place. A well tested system has lots of unit tests, a reasonable number of integration tests, and some end-to-end tests. KUnit is just trying to address the unit test space which is currently not being addressed. ### More information on KUnit There is a bunch of documentation near the end of this patch set that describes how to use KUnit and best practices for writing unit tests. For convenience I am hosting the compiled docs here[4]. Additionally for convenience, I have applied these patches to a branch[5]. The repo may be cloned with: git clone https://kunit.googlesource.com/linux This patchset is on the kunit/initial/v5.3/v18 branch. ## History since v15 ### v18 - Addrssed comments on 07/19 (kunit: test: add initial tests) from Randy Dunlap by removing redundant dependencies from Kconfig entries. ### v17 - Addressed comments on 06/19 (lib: enable building KUnit in lib/) from Stephen Boyd by moving KUnit submenu ahead of Runtime Testing submenu. ### v16 - Addressed comments from Linus Torvalds by moving all kunit/ paths to lib/kunit/. - Addressed comments by Randy Dunlap by moving KUnit Kconfig under lib/Kconfig.debug so the KUnit submenu shows up under the "Kernel Hacking" menu.

[RFC PATCH] selftests: fix build targets behaviour on failures

by Cristian Marussi

Currently, when some of the KSFT subsystems specified in TARGETS fails to build, the toplevel Makefile just keeps carrying on with the build process. This behaviour is expected and desirable especially in the context of a CI system running KSelfTest where is not always easy to guarantee that the most recent and esoteric toolchain's dependencies are respected across all KSFT TARGETS in a timely manner. Unfortunately, as of now, this holds true only if the very last of the subsystems listed in TARGETS happened to be one that could be successfully built: if the last listed TARGETS fails, it is taken as the whole outcome of the Makefile target and the complete build/install halts even though many other preceding subsytems were in fact already successfully built. Fix the KSFT Makefile behaviour related to all/install targets in order to fail as a whole only when the all/install targets have failed for all of the requested TARGETS, while succeeding when at least one of TARGETS has been successfully built.

Enter these 2 lines: > ip(){ return 0; } > export -f ip Now try the #!/bin/bash script. If that now fails, try again with #!/bin/bash changed to #!/bin/bash -p Any better now? Cheers ... Duncan.

Linux 5.4 kselftest known issues

by Shuah Khan

Here are the know kselftest issues on Linux 5.4 with top commit commit 619e17cf75dd58905aa67ccd494a6ba5f19d6cc6 on x86_64: The goal is to get these addressed before 5.4 comes out. 3 build failures and status: pidfd - undefined reference to `pthread_create' collect2: error: ld returned 1 exit status Fixed: https://patchwork.kernel.org/patch/11159517/ bfp (two issues) 1. "make TARGETS=bpf kselftest" build fails Makefile:127: tools/build/Makefile.include: No such file or directory This is due to recent kbuild changes and I have a patch ready to send. 2. Related to llvm latest version dependency. This is a hard dependency. Unless users upgrade to latest llvvm, bpf test won't run. The new llvm might not be supported on all distros yet, in which case bpf will not get tested in some rings and on some architectures. gpio "make TARGETS=gpio kselftest" build fails Makefile:23: tools/build/Makefile.include: No such file or directory This is due to recent kbuild changes and I have a patch ready to send. kvm "make TARGETS=kvm kselftest" build fails due --no-pie flags. I am working on a fix for this. no-pie-option defines aren't working correctly and I suspect try-run miht not be defined in this kselftest build case. thanks, -- Shuah
