[PATCH] selftests: hid: fix vmtests.sh not running make headers

by Benjamin Tissoires

According to commit 01d6c48a828b ("Documentation: kselftest: "make headers" is a prerequisite"), running the kselftests requires to run "make headers" first. Do that in "vmtest.sh" as well to fix the HID CI. Signed-off-by: Benjamin Tissoires <bentiss(a)kernel.org> --- Looks like the new master branch (v6.5-rc1) broke my CI. And given that `make headers` is now a requisite to run the kselftests, also include that command in vmtests.sh. Broken CI job: https://gitlab.freedesktop.org/bentiss/hid/-/jobs/44704436 Fixed CI job: https://gitlab.freedesktop.org/bentiss/hid/-/jobs/45151040 --- tools/testing/selftests/hid/vmtest.sh | 1 + 1 file changed, 1 insertion(+) diff --git a/tools/testing/selftests/hid/vmtest.sh b/tools/testing/selftests/hid/vmtest.sh index 681b906b4853..4da48bf6b328 100755 --- a/tools/testing/selftests/hid/vmtest.sh +++ b/tools/testing/selftests/hid/vmtest.sh @@ -79,6 +79,7 @@ recompile_kernel() cd "${kernel_checkout}" ${make_command} olddefconfig + ${make_command} headers ${make_command} } --- base-commit: 0e382fa72bbf0610be40af9af9b03b0cd149df82 change-id: 20230709-fix-selftests-c8b0bdff1d20 Best regards, -- Benjamin Tissoires <bentiss(a)kernel.org>

[PATCH v1 0/5] selftests/nolibc: report: print test status

by Zhangjin Wu

Hi, Willy As you suggested, the 'status: [success|warning|failure]' info is added to the summary line, with additional newlines around this line to extrude the status info. at the same time, the total tests is printed, the passed, skipped and failed values are aligned with '%03d'. This patchset is based on 20230705-nolibc-series2 of nolibc repo[1]. The test result looks like: ... 138 test(s): 135 passed, 002 skipped, 001 failed => status: failure See all results in /labs/linux-lab/src/linux-stable/tools/testing/selftests/nolibc/run.out Or: ... 137 test(s): 134 passed, 003 skipped, 000 failed => status: warning See all results in /labs/linux-lab/src/linux-stable/tools/testing/selftests/nolibc/run.out Best regards, Zhangjin --- [1]: https://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/nolibc.git Zhangjin Wu (5): selftests/nolibc: report: print a summarized test status selftests/nolibc: report: print total tests selftests/nolibc: report: align passed, skipped and failed selftests/nolibc: report: extrude the test status line selftests/nolibc: report: add newline before test failures tools/testing/selftests/nolibc/Makefile | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) -- 2.25.1

It's also documentation. The two are related, as one is the hand off to the other. It's not a random union, and I'd like to leave it that way. -- Steve

[PATCH v4 0/4] RISC-V: mm: Make SV48 the default address space

by Charlie Jenkins

Make sv48 the default address space for mmap as some applications currently depend on this assumption. Also enable users to select desired address space using a non-zero hint address to mmap. Previous kernel changes caused Java and other applications to be broken on sv57 which this patch fixes. Documentation is also added to the RISC-V virtual memory section to explain these changes. -Charlie --- v4: - Split testcases/document patch into test cases, in-code documentation, and formal documentation patches - Modified the mmap_base macro to be more legible and better represent memory layout - Fixed documentation to better reflect the implmentation - Renamed DEFAULT_VA_BITS to MMAP_VA_BITS - Added additional test case for rlimit changes --- Charlie Jenkins (4): RISC-V: mm: Restrict address space for sv39,sv48,sv57 RISC-V: mm: Add tests for RISC-V mm RISC-V: mm: Update pgtable comment documentation RISC-V: mm: Document mmap changes Documentation/riscv/vm-layout.rst | 22 +++ arch/riscv/include/asm/elf.h | 2 +- arch/riscv/include/asm/pgtable.h | 21 ++- arch/riscv/include/asm/processor.h | 43 +++++- tools/testing/selftests/riscv/Makefile | 2 +- tools/testing/selftests/riscv/mm/.gitignore | 1 + tools/testing/selftests/riscv/mm/Makefile | 21 +++ .../selftests/riscv/mm/testcases/mmap.c | 133 ++++++++++++++++++ 8 files changed, 232 insertions(+), 13 deletions(-) create mode 100644 tools/testing/selftests/riscv/mm/.gitignore create mode 100644 tools/testing/selftests/riscv/mm/Makefile create mode 100644 tools/testing/selftests/riscv/mm/testcases/mmap.c -- 2.41.0

[PATCH v3 0/8] add UFFDIO_POISON to simulate memory poisoning with UFFD

by Axel Rasmussen

This series adds a new userfaultfd feature, UFFDIO_POISON. See commit 4 for a detailed description of the feature. The series is based on Linus master (partial 6.5 merge window), and structured like this: - Patches 1-3 are preparation / refactoring - Patches 4-6 implement and advertise the new feature - Patches 7-8 implement a unit test for the new feature Changelog: v2 -> v3: - Rebase onto current Linus master. - Don't overwrite existing PTE markers for non-hugetlb UFFDIO_POISON. Before, non-hugetlb would override them, but hugetlb would not. I don't think there's a use case where we *want* to override a UFFD_WP marker for example, so take the more conservative behavior for all kinds of memory. - [Peter] Drop hugetlb mfill atomic refactoring, since it isn't needed for this series (we don't touch that code directly anyway). - [Peter] Switch to re-using PTE_MARKER_SWAPIN_ERROR instead of defining new PTE_MARKER_UFFD_POISON. - [Peter] Extract start / len range overflow check into existing validate_range helper; this fixes the style issue of unnecessary braces in the UFFDIO_POISON implementation, because this code is just deleted. - [Peter] Extract file size check out into a new helper. - [Peter] Defer actually "enabling" the new feature until the last commit in the series; combine this with adding the documentation. As a consequence, move the selftest commits after this one. - [Randy] Fix typo in documentation. v1 -> v2: - [Peter] Return VM_FAULT_HWPOISON not VM_FAULT_SIGBUS, to yield the correct behavior for KVM (guest MCE). - [Peter] Rename UFFDIO_SIGBUS to UFFDIO_POISON. - [Peter] Implement hugetlbfs support for UFFDIO_POISON.

ww_mutex.sh hangs since v5.16-rc1

by Li Zhijian

Hi Folks LKP/0Day found that ww_mutex.sh cannot complete since v5.16-rc1, but I'm pretty sorry that we failed to bisect the FBC, instead, the bisection pointed to a/below merge commit(91e1c99e17) finally. Due to this hang, other tests in the same group are also blocked in 0Day, we hope we can fix this hang ASAP. So if you have any idea about this, or need more debug information, feel free to let me know :) BTW, ww_mutex.sh was failed in v5.15 without hang, and looks it cannot reproduce on a vm.

[PATCH v2 bpf-next] selftests/bpf: Corrected two typos

by Lu Hongfei

When wrapping code, use ';' better than using ',' which is more in line with the coding habits of most engineers.
