[PATCH] kunit: Reset suite counter right before running tests

by Michal Wajdeczko

Today we reset the suite counter as part of the suite cleanup, called from the module exit callback, but it might not work that well as one can try to collect results without unloading a previous test (either unintentionally or due to dependencies). For easy reproduction try to load the kunit-test.ko and then collect and parse results from the kunit-example-test.ko load. Parser will complain about mismatch of expected test number: [ ] KTAP version 1 [ ] 1..1 [ ] # example: initializing suite [ ] KTAP version 1 [ ] # Subtest: example .. [ ] # example: pass:5 fail:0 skip:4 total:9 [ ] # Totals: pass:6 fail:0 skip:6 total:12 [ ] ok 7 example [ ] [ERROR] Test: example: Expected test number 1 but found 7 [ ] ===================== [PASSED] example ===================== [ ] ============================================================ [ ] Testing complete. Ran 12 tests: passed: 6, skipped: 6, errors: 1 Since we are now printing suite test plan on every module load, right before running suite tests, we should make sure that suite counter will also start from 1. Easiest solution seems to be move counter reset to the __kunit_test_suites_init() function.

[PATCH RFC] tools/nolibc: add support for constructors and destructors

[PATCH v2 0/3] userfaultfd remap option

by Suren Baghdasaryan

This patch series introduces UFFDIO_REMAP feature to userfaultfd, which has long been implemented and maintained by Andrea in his local tree [1], but was not upstreamed due to lack of use cases where this approach would be better than allocating a new page and copying the contents. UFFDIO_COPY performs ~20% better than UFFDIO_REMAP when the application needs pages to be allocated [2]. However, with UFFDIO_REMAP, if pages are available (in userspace) for recycling, as is usually the case in heap compaction algorithms, then we can avoid the page allocation and memcpy (done by UFFDIO_COPY). Also, since the pages are recycled in the userspace, we avoid the need to release (via madvise) the pages back to the kernel [3]. We see over 40% reduction (on a Google pixel 6 device) in the compacting thread’s completion time by using UFFDIO_REMAP vs. UFFDIO_COPY. This was measured using a benchmark that emulates a heap compaction implementation using userfaultfd (to allow concurrent accesses by application threads). More details of the usecase are explained in [3]. Furthermore, UFFDIO_REMAP enables remapping swapped-out pages without touching them within the same vma. Today, it can only be done by mremap, however it forces splitting the vma. Main changes since Andrea's last version [1]: - Trivial translations from page to folio, mmap_sem to mmap_lock - Replace pmd_trans_unstable() with pte_offset_map_nolock() and handle its possible failure - Move pte mapping into remap_pages_pte to allow for retries when source page or anon_vma is contended. Since pte_offset_map_nolock() start RCU read section, we can't block anymore after mapping a pte, so have to unmap the ptesm do the locking and retry. - Add and use anon_vma_trylock_write() to avoid blocking while in RCU read section. - Accommodate changes in mmu_notifier_range_init() API, switch to mmu_notifier_invalidate_range_start_nonblock() to avoid blocking while in RCU read section. - Open-code now removed __swp_swapcount() - Replace pmd_read_atomic() with pmdp_get_lockless() - Add new selftest for UFFDIO_REMAP Changes since v1 [4]: - add mmget_not_zero in userfaultfd_remap, per Jann Horn - removed extern from function definitions, per Matthew Wilcox - converted to folios in remap_pages_huge_pmd, per Matthew Wilcox - use PageAnonExclusive in remap_pages_huge_pmd, per David Hildenbrand - handle pgtable transfers between MMs, per Jann Horn - ignore concurrent A/D pte bit changes, per Jann Horn - split functions into smaller units, per David Hildenbrand - test for folio_test_large in remap_anon_pte, per Matthew Wilcox - use pte_swp_exclusive for swapcount check, per David Hildenbrand - eliminated use of mmu_notifier_invalidate_range_start_nonblock, per Jann Horn - simplified THP alignment checks, per Jann Horn - refactored the loop inside remap_pages, per Jann Horn - additional clarifying comments, per Jann Horn [1] https://gitlab.com/aarcange/aa/-/commit/2aec7aea56b10438a3881a20a411aa4b1fc… [2] https://lore.kernel.org/all/1425575884-2574-1-git-send-email-aarcange@redha… [3] https://lore.kernel.org/linux-mm/CA+EESO4uO84SSnBhArH4HvLNhaUQ5nZKNKXqxRCyj… [4] https://lore.kernel.org/all/20230914152620.2743033-1-surenb@google.com/ Andrea Arcangeli (2): userfaultfd: UFFDIO_REMAP: rmap preparation userfaultfd: UFFDIO_REMAP uABI Suren Baghdasaryan (1): selftests/mm: add UFFDIO_REMAP ioctl test fs/userfaultfd.c | 63 ++ include/linux/rmap.h | 5 + include/linux/userfaultfd_k.h | 12 + include/uapi/linux/userfaultfd.h | 22 + mm/huge_memory.c | 130 ++++ mm/khugepaged.c | 3 + mm/rmap.c | 13 + mm/userfaultfd.c | 590 +++++++++++++++++++ tools/testing/selftests/mm/uffd-common.c | 41 +- tools/testing/selftests/mm/uffd-common.h | 1 + tools/testing/selftests/mm/uffd-unit-tests.c | 62 ++ 11 files changed, 940 insertions(+), 2 deletions(-) -- 2.42.0.515.g380fc7ccd1-goog

[PATCH v2] selftests/user_events: Fix abi_test for BE archs

by Beau Belgrave

The abi_test currently uses a long sized test value for enablement checks. On LE this works fine, however, on BE this results in inaccurate assert checks due to a bit being used and assuming it's value is the same on both LE and BE. Use int type for 32-bit values and long type for 64-bit values to ensure appropriate behavior on both LE and BE.
