[PATCH v1] selftests: Use optional USERCFLAGS and USERLDFLAGS

by Mickaël Salaün

This change enables to extend CFLAGS and LDFLAGS from command line, e.g. to extend compiler checks: make USERCFLAGS=-Werror USERLDFLAGS=-static USERCFLAGS and USERLDFLAGS are documented in Documentation/kbuild/makefiles.rst and Documentation/kbuild/kbuild.rst This should be backported (down to 5.10) to improve previous kernel versions testing as well.

[PATCH] kasan: Enable KUnit integration whenever CONFIG_KUNIT is enabled

by David Gow

Enable the KASAN/KUnit integration even when the KASAN tests are disabled, as it's useful for testing other things under KASAN. Essentially, this reverts commit 49d9977ac909 ("kasan: check CONFIG_KASAN_KUNIT_TEST instead of CONFIG_KUNIT"). To mitigate the performance impact slightly, add a likely() to the check for a currently running test. There's more we can do for performance if/when it becomes more of a problem, such as only enabling the "expect a KASAN failure" support wif the KASAN tests are enabled, or putting the whole thing behind a "kunit tests are running" static branch (which I do plan to do eventually). Fixes: 49d9977ac909 ("kasan: check CONFIG_KASAN_KUNIT_TEST instead of CONFIG_KUNIT") Signed-off-by: David Gow <davidgow(a)google.com> --- Basically, hiding the KASAN/KUnit integration broke being able to just pass --kconfig_add CONFIG_KASAN=y to kunit_tool to enable KASAN integration. We didn't notice this, because usually CONFIG_KUNIT_ALL_TESTS is enabled, which in turn enables CONFIG_KASAN_KUNIT_TEST. However, using a separate .kunitconfig might result in failures being missed. Take, for example: ./tools/testing/kunit/kunit.py run --kconfig_add CONFIG_KASAN=y \ --kunitconfig drivers/gpu/drm/tests This should run the drm tests with KASAN enabled, but even if there's a KASAN failure (such as the one fixed by [1]), kunit_tool will report success.

[PATCH v1] selftests/landlock: Build without static libraries

by Mickaël Salaün

The only (forced) static test binary doesn't depend on libcap. Because using -lcap on systems that don't have such static library would fail (e.g. on Arch Linux), let's be more specific and require only dynamic libcap linking.

[PATCH v11 0/2] SPDX: add copyleft-next-0.3.1

by Luis Chamberlain

As suggested by Thomas Gleixner, I'm following up to move on with the SPDX tag needed for copyleft-next-0.3.1. I've split this out from the test_sysfs selftest so to separate review from that. Changes on this v11: o Fixed a minor typo on patch #2 as noted by Kees Cook o Added Reviewed-by tags by Kees Cook Changes on this v10: o embraced paragraph from Thomas Gleixner which helps explain why the OR operator in the SPDX license name o dropped the GPL-2.0 and GPL-2.0+ tags as suggested by Thomas Gleixner as these are outdated (still valid) in the SPDX spec o trimmed the Cc list to remove the test_sysfs / block layer / fs folks as the test_sysfs stuff is now dropped from consideration in this series Prior to this the series was at v9 but it also had the test_sysfs and its changes, its history can be found here: https://lore.kernel.org/all/20211029184500.2821444-1-mcgrof@kernel.org/ Luis Chamberlain (2): LICENSES: Add the copyleft-next-0.3.1 license testing: use the copyleft-next-0.3.1 SPDX tag LICENSES/dual/copyleft-next-0.3.1 | 236 +++++++++++++++++++++++ lib/test_kmod.c | 12 +- lib/test_sysctl.c | 12 +- tools/testing/selftests/kmod/kmod.sh | 13 +- tools/testing/selftests/sysctl/sysctl.sh | 12 +- 5 files changed, 240 insertions(+), 45 deletions(-) create mode 100644 LICENSES/dual/copyleft-next-0.3.1 -- 2.35.1

[PATCH v3 0/4] Implement IOCTL to get and clear soft dirty PTE

by Muhammad Usama Anjum

Hello, This patch series implements a new ioctl on the pagemap proc fs file to get, clear and perform both get and clear at the same time atomically on the specified range of the memory. Soft-dirty PTE bit of the memory pages can be viewed by using pagemap procfs file. The soft-dirty PTE bit for the whole memory range of the process can be cleared by writing to the clear_refs file. This series adds features that weren't present earlier. - There is no atomic get soft-dirty PTE bit status and clear operation present. - The soft-dirty PTE bit of only a part of memory cannot be cleared. Historically, soft-dirty PTE bit tracking has been used in the CRIU project. The proc fs interface is enough for that as I think the process is frozen. We have the use case where we need to track the soft-dirty PTE bit for the running processes. We need this tracking and clear mechanism of a region of memory while the process is running to emulate the getWriteWatch() syscall of Windows. This syscall is used by games to keep track of dirty pages and keep processing only the dirty pages. This new ioctl can be used by the CRIU project and other applications which require soft-dirty PTE bit information. As in the current kernel there is no way to clear a part of memory (instead of clearing the Soft-Dirty bits for the entire process) and get+clear operation cannot be performed atomically, there are other methods to mimic this information entirely in userspace with poor performance: - The mprotect syscall and SIGSEGV handler for bookkeeping - The userfaultfd syscall with the handler for bookkeeping Some benchmarks can be seen [1]. This ioctl can be used by the CRIU project and other applications which require soft-dirty PTE bit information. The following operations are supported in this ioctl: - Get the pages that are soft-dirty. - Clear the pages which are soft-dirty. - The optional flag to ignore the VM_SOFTDIRTY and only track per page soft-dirty PTE bit There are two decisions which have been taken about how to get the output from the syscall. - Return offsets of the pages from the start in the vec - Stop execution when vec is filled with dirty pages These two arguments doesn't follow the mincore() philosophy where the output array corresponds to the address range in one to one fashion, hence the output buffer length isn't passed and only a flag is set if the page is present. This makes mincore() easy to use with less control. We are passing the size of the output array and putting return data consecutively which is offset of dirty pages from the start. The user can convert these offsets back into the dirty page addresses easily. Suppose, the user want to get first 10 dirty pages from a total memory of 100 pages. He'll allocate output buffer of size 10 and the ioctl will abort after finding the 10 pages. This behaviour is needed to support Windows' getWriteWatch(). The behaviour like mincore() can be achieved by passing output buffer of 100 size. This interface can be used for any desired behaviour.
