v4: - add more reviews (mimi, luis) - adjusted comment (mimi) - fixed build error when not building firmware tests (0day, sfr) - fixed needless .xz read (tiwai) - rebased to driver-core-next v3: https://lore.kernel.org/lkml/20200724213640.389191-1-keescook@chromium.org/ v2: lost to the ether v1: https://lore.kernel.org/lkml/20200717174309.1164575-1-keescook@chromium.org/ Hi, Here's my tree for adding partial read support in kernel_read_file(), which fixes a number of issues along the way. It's got Scott's firmware and IMA patches ported and everything tests cleanly for me (even with CONFIG_IMA_APPRAISE=y), and now appears to pass 0day. :) The intention is for this to go via Greg's tree since Scott's driver code will depend on it.

[PATCH] selftests: more general make nesting support

by Greg Thelen

selftests can be built from the toplevel kernel makefile (e.g. make kselftest-all) or directly (make -C tools/testing/selftests all). The toplevel kernel makefile explicitly disables implicit rules with "MAKEFLAGS += -rR", which is passed to tools/testing/selftests. Some selftest makefiles require implicit make rules, which is why commit 67d8712dcc70 ("selftests: Fix build failures when invoked from kselftest target") reenables implicit rules by clearing MAKEFLAGS if MAKELEVEL=1. So far so good. However, if the toplevel makefile is called from an outer makefile then MAKELEVEL will be elevated, which breaks the MAKELEVEL equality test. Example wrapped makefile error: $ cat ~/Makefile all: $(MAKE) defconfig $(MAKE) kselftest-all $ make -sf ~/Makefile futex_wait_timeout.c /src/tools/testing/selftests/kselftest_harness.h /src/tools/testing/selftests/kselftest.h ../include/futextest.h ../include/atomic.h ../include/logging.h -lpthread -lrt -o /src/tools/testing/selftests/futex/functional/futex_wait_timeout make[4]: futex_wait_timeout.c: Command not found Rather than checking $(MAKELEVEL), check for $(LINK.c), which is a more direct side effect of "make -R". This enables arbitrary makefile nesting.

[PATCH 0/2] selftests: rtnetlink: Fix for false-negative return values

by Po-Hsu Lin

This patchset will address the false-negative return value issue caused by the following: 1. The return value "ret" in this script will be reset to 0 from the beginning of each sub-test in rtnetlink.sh, therefore this rtnetlink test will always pass if the last sub-test has passed. 2. The test result from two sub-tests in kci_test_encap() were not being processed, thus they will not affect the final test result of this test.

[PATCH v10 0/5] KASAN-KUnit Integration

by David Gow

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. This patchset depends on: - "kunit: extend kunit resources API" [1] - This is already present in the kselftest/kunit branch I'd _really_ like to get this into 5.9 if possible: we also have some other changes which depend on some things here. Changes from v9: - Rebased on top of linux-next (20200731) + kselftest/kunit and [7] - Note that the kasan_rcu_uaf test has not been ported to KUnit, and remains in test_kasan_module. This is because: (a) KUnit's expect failure will not check if the RCU stacktraces show. (b) KUnit is unable to link the failure to the test, as it occurs in an RCU callback. Changes from v8: - Rebased on top of kselftest/kunit - (Which, with this patchset, should rebase cleanly on 5.8-rc7) - Renamed the KUnit test suite, config name to patch the proposed naming guidelines for KUnit tests[6] Changes from v7: - Rebased on top of kselftest/kunit - Rebased on top of v4 of the kunit resources API[1] - Rebased on top of v4 of the FORTIFY_SOURCE fix[2,3,4] - Updated the Kconfig entry to support KUNIT_ALL_TESTS Changes from v6: - Rebased on top of kselftest/kunit - Rebased on top of Daniel Axtens' fix for FORTIFY_SOURCE incompatibilites [2] - Removed a redundant report_enabled() check. - Fixed some places with out of date Kconfig names in the documentation. Changes from v5: - Split out the panic_on_warn changes to a separate patch. - Fix documentation to fewer to the new Kconfig names. - Fix some changes which were in the wrong patch. - Rebase on top of kselftest/kunit (currently identical to 5.7-rc1) Changes from v4: - KASAN no longer will panic on errors if both panic_on_warn and kasan_multishot are enabled. - As a result, the KASAN tests will no-longer disable panic_on_warn. - This also means panic_on_warn no-longer needs to be exported. - The use of temporary "kasan_data" variables has been cleaned up somewhat. - A potential refcount/resource leak should multiple KASAN errors appear during an assertion was fixed. - Some wording changes to the KASAN test Kconfig entries. 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(). Changes since v2: - Due to Alan's changes in [1], KUnit can be built as a module. - The name of the tests that could not be run with KUnit has been changed to be more generic: test_kasan_module. - Documentation on how to run the new KASAN tests and what to expect when running them has been added. - Some variables and functions are now static. - Now save/restore panic_on_warn in a similar way to kasan_multi_shot and renamed the init/exit functions to be more generic to accommodate. - Due to [4] in kasan_strings, kasan_memchr, and kasan_memcmp will fail if CONFIG_AMD_MEM_ENCRYPT is enabled so return early and print message explaining this circumstance. - Changed preprocessor checks to C checks where applicable. Changes since v1: - Make use of Alan Maguire's suggestion to use his patch that allows static resources for integration instead of adding a new attribute to the kunit struct - All KUNIT_EXPECT_KASAN_FAIL statements are local to each test - The definition of KUNIT_EXPECT_KASAN_FAIL is local to the test_kasan.c file since it seems this is the only place this will be used. - Integration relies on KUnit being builtin - copy_user_test has been separated into its own file since KUnit is unable to test these. This can be run as a module just as before, using CONFIG_TEST_KASAN_USER - The addition to the current task has been separated into its own patch as this is a significant enough change to be on its own.

[PATCH v5 00/12] kunit: create a centralized executor to dispatch all KUnit tests

by Brendan Higgins

## TL;DR This patchset adds a centralized executor to dispatch tests rather than relying on late_initcall to schedule each test suite separately along with a couple of new features that depend on it. ## What am I trying to do? Conceptually, I am trying to provide a mechanism by which test suites can be grouped together so that they can be reasoned about collectively. The last two of three patches in this series add features which depend on this: PATCH 09/12 Prints out a test plan[1] right before KUnit tests are run; this is valuable because it makes it possible for a test harness to detect whether the number of tests run matches the number of tests expected to be run, ensuring that no tests silently failed. The test plan includes a count of tests that will run. With the centralized executor, the tests are located in a single data structure and thus can be counted. PATCH 10/12 Add a new kernel command-line option which allows the user to specify that the kernel poweroff, halt, or reboot after completing all KUnit tests; this is very handy for running KUnit tests on UML or a VM so that the UML/VM process exits cleanly immediately after running all tests without needing a special initramfs. The centralized executor provides a definitive point when all tests have completed and the poweroff, halt, or reboot could occur. In addition, by dispatching tests from a single location, we can guarantee that all KUnit tests run after late_init is complete, which was a concern during the initial KUnit patchset review (this has not been a problem in practice, but resolving with certainty is nevertheless desirable). Other use cases for this exist, but the above features should provide an idea of the value that this could provide. ## Changes since last revision: - Fixed a compilation error in the centralized executor patch (07/12). I had forgotten to test the patches when building as modules. I verified that works now. - I accidentally merged patches 09/12 and 10/12 in the previous revision (v4), and made them separate patches again. ## Changes since v3: - On the last revision I got some messages from 0day that showed that this patchset didn't work on several architectures, one issue that this patchset addresses is that we were aligning both memory segments as well as structures in the segments to specific byte boundaries which was incorrect. - The issue mentioned above also caused me to test on additional architectures which revealed that some architectures other than UML do not use the default init linker section macro that most architectures use. There are now several new patches (2, 3, 4, and 6). - Fixed a formatting consistency issue in the kernel params documentation patch (11/12). - Add a brief blurb on how and when the kunit_test_suite macro works. ## Remaining work to be done: The only architecture for which I was able to get a compiler, but was apparently unable to get KUnit into a section that the executor to see was m68k - not sure why.

[PATCH v4 0/2] Syscall User Redirection

by Gabriel Krisman Bertazi

Hi, This is v4 of Syscall User Redirection. The implementation itself is not modified from v3, it only applies the latest round of reviews to the selftests. __NR_syscalls is not really exported in header files other than asm-generic for every architecture, so it felt safer to optionally expose it with a fallback to a high value. Also, I didn't expose tests for PR_GET as that is not currently implemented. If possible, I'd have it supported by a future patchset, since it is not immediately necessary to support this feature. Finally, one question: Which tree would this go through?
