[PATCH v2] kunit: Fix kunit.py run --build_dir='<foo>' fails on "unclean" trees

by Vitor Massaru Iha

Fix this bug: https://bugzilla.kernel.org/show_bug.cgi?id=205219 For some reason, the environment variable ARCH is used instead of ARCH passed as an argument, this patch uses a copy of the env, but using ARCH=um and CROSS_COMPILER='' to avoid this problem. This patch doesn't change the user's environment variables, avoiding side effects.

[PATCH v4 0/4] KUnit-KASAN Integration

by Patricia Alfonso

This patchset contains everything needed to integrate KASAN and KUnit. KUnit will be able to: (1) Fail tests when an unexpected KASAN error occurs (2) Pass tests when an expected KASAN error occurs Convert KASAN tests to KUnit with the exception of copy_user_test because KUnit is unable to test those. Add documentation on how to run the KASAN tests with KUnit and what to expect when running these tests. Depends on "[PATCH v3 kunit-next 0/2] kunit: extend kunit resources API" patchset [1] [1] https://lore.kernel.org/linux-kselftest/1585313122-26441-1-git-send-email-a… Changes from v3: - KUNIT_SET_KASAN_DATA and KUNIT_DO_EXPECT_KASAN_FAIL have been combined and included in KUNIT_DO_EXPECT_KASAN_FAIL() instead. - Reordered logic in kasan_update_kunit_status() in report.c to be easier to read. - Added comment to not use the name "kasan_data" for any kunit tests outside of KUNIT_EXPECT_KASAN_FAIL().
