Hi, This patch series moves KUnit test execution at the very end of kernel initialization, just before launching the init process. This opens the way to test any kernel code in its normal state (i.e. fully initialized). This patch series also teaches KUnit to handle kthread faults as errors, and it brings a few related fixes and improvements. New tests check NULL pointer dereference and read-only memory, which wasn't possible before. This is useful to test current kernel self-protection mechanisms or future ones such as Heki: https://github.com/heki-linux Regards, Mickaël Salaün (8): kunit: Run tests when the kernel is fully setup kunit: Handle thread creation error kunit: Fix kthread reference kunit: Fix timeout message kunit: Handle test faults kunit: Fix KUNIT_SUCCESS() calls in iov_iter tests kunit: Print last test location on fault kunit: Add tests for faults include/kunit/test.h | 24 +++++- include/kunit/try-catch.h | 3 - init/main.c | 4 +- lib/bitfield_kunit.c | 8 +- lib/checksum_kunit.c | 2 +- lib/kunit/executor.c | 81 ++++++++++++++------ lib/kunit/kunit-example-test.c | 6 +- lib/kunit/kunit-test.c | 115 +++++++++++++++++++++++++++- lib/kunit/try-catch.c | 33 +++++--- lib/kunit_iov_iter.c | 70 ++++++++--------- tools/testing/kunit/kunit_kernel.py | 6 +- 11 files changed, 261 insertions(+), 91 deletions(-) base-commit: d206a76d7d2726f3b096037f2079ce0bd3ba329b -- 2.44.0
