by vivekyadav1207731111＠gmail.com

From: Vivek Yadav <vivekyadav1207731111(a)gmail.com> Hi all, This small series makes cosmetic style cleanups in the arm64 kselftests to improve readability and suppress checkpatch warnings. These changes are purely cosmetic and do not affect functionality. Changes in this series: * Suppress unnecessary checkpatch warning in a comment * Add parentheses around sizeof for clarity * Remove redundant blank line --- Vivek Yadav (3): kselftest/arm64: Remove extra blank line kselftest/arm64: Supress warning and improve readability kselftest/arm64: Add parentheses around sizeof for clarity tools/testing/selftests/arm64/abi/hwcap.c | 1 - tools/testing/selftests/arm64/bti/assembler.h | 1 - tools/testing/selftests/arm64/fp/fp-ptrace.c | 1 - tools/testing/selftests/arm64/fp/fp-stress.c | 4 ++-- tools/testing/selftests/arm64/fp/sve-ptrace.c | 2 +- tools/testing/selftests/arm64/fp/vec-syscfg.c | 1 - tools/testing/selftests/arm64/fp/zt-ptrace.c | 1 - tools/testing/selftests/arm64/gcs/gcs-locking.c | 1 - 8 files changed, 3 insertions(+), 9 deletions(-) -- 2.25.1

[PATCH 0/4] selftests/mm/uffd: refactor global variables

by Ujwal Kundur

This patchset refactors non-composite global variables into a common struct that can be initialized and passed around per-test instead of relying on the presence of global variables. This allows: - Better encapsulation - Debugging becomes easier -- local variable state can be viewed per stack frame, and we can more easily reason about the variable mutations Patch 1 needs to be applied first and can be followed by any of the other patches. I've ensured that the tests are passing locally (or atleast have the same output as the code on master).

[PATCH net] selftests: tls: make the new data_steal test less flaky

by Jakub Kicinski

The CI has hit a couple of cases of: RUN global.data_steal ... tls.c:2762:data_steal:Expected recv(cfd, buf2, sizeof(buf2), MSG_DONTWAIT) (20000) == -1 (-1) data_steal: Test terminated by timeout FAIL global.data_steal Looks like the 2msec sleep is not long enough. Make the sleep longer, and then instead of second sleep wait for the thieving process to exit. That way we can be sure it called recv() before us. While at it also avoid trying to steal more than a record, this seems to be causing issues in manual testing as well.

[PATCH v18 0/8] fork: Support shadow stacks in clone3()

by Mark Brown

The kernel has recently added support for shadow stacks, currently x86 only using their CET feature but both arm64 and RISC-V have equivalent features (GCS and Zicfiss respectively), I am actively working on GCS[1]. With shadow stacks the hardware maintains an additional stack containing only the return addresses for branch instructions which is not generally writeable by userspace and ensures that any returns are to the recorded addresses. This provides some protection against ROP attacks and making it easier to collect call stacks. These shadow stacks are allocated in the address space of the userspace process. Our API for shadow stacks does not currently offer userspace any flexiblity for managing the allocation of shadow stacks for newly created threads, instead the kernel allocates a new shadow stack with the same size as the normal stack whenever a thread is created with the feature enabled. The stacks allocated in this way are freed by the kernel when the thread exits or shadow stacks are disabled for the thread. This lack of flexibility and control isn't ideal, in the vast majority of cases the shadow stack will be over allocated and the implicit allocation and deallocation is not consistent with other interfaces. As far as I can tell the interface is done in this manner mainly because the shadow stack patches were in development since before clone3() was implemented. Since clone3() is readily extensible let's add support for specifying a shadow stack when creating a new thread or process, keeping the current implicit allocation behaviour if one is not specified either with clone3() or through the use of clone(). The user must provide a shadow stack pointer, this must point to memory mapped for use as a shadow stackby map_shadow_stack() with an architecture specified shadow stack token at the top of the stack. Yuri Khrustalev has raised questions from the libc side regarding discoverability of extended clone3() structure sizes[2], this seems like a general issue with clone3(). There was a suggestion to add a hwcap on arm64 which isn't ideal but is doable there, though architecture specific mechanisms would also be needed for x86 (and RISC-V if it's support gets merged before this does). The idea has, however, had strong pushback from the architecture maintainers and it is possible to detect support for this in clone3() by attempting a call with a misaligned shadow stack pointer specified so no hwcap has been added.

[PATCH v3 0/7] kunit: Refactor and extend KUnit's parameterized testing framework

by Marie Zhussupova

Hello! KUnit offers a parameterized testing framework, where tests can be run multiple times with different inputs. However, the current implementation uses the same `struct kunit` for each parameter run. After each run, the test context gets cleaned up, which creates the following limitations: a. There is no way to store resources that are accessible across the individual parameter runs. b. It's not possible to pass additional context, besides the previous parameter (and potentially anything else that is stored in the current test context), to the parameter generator function. c. Test users are restricted to using pre-defined static arrays of parameter objects or generate_params() to define their parameters. There is no flexibility to make a custom dynamic array without using generate_params(), which can be complex if generating the next parameter depends on more than just the single previous parameter. This patch series resolves these limitations by: 1. [P 1] Giving each parameterized run its own `struct kunit`. It will remove the need to manage state, such as resetting the `test->priv` field or the `test->status_comment` after every parameter run. 2. [P 1] Introducing parameterized test context available to all parameter runs through the parent pointer of type `struct kunit`. This context won't be used to execute any test logic, but will instead be used for storing shared resources. Each parameter run context will have a reference to that parent instance and thus, have access to those resources. 3. [P 2] Introducing param_init() and param_exit() functions that can initialize and exit the parameterized test context. They will run once before and after the parameterized test. param_init() can be used to add resources to share between parameter runs, pass parameter arrays, and any other setup logic. While param_exit() can be used to clean up resources that were not managed by the parameterized test, and any other teardown logic. 4. [P 3] Passing the parameterized test context as an additional argument to generate_params(). This provides generate_params() with more context, making parameter generation much more flexible. The generate_params() implementations in the KCSAN and drm/xe tests have been adapted to match the new function pointer signature. 5. [P 4] Introducing a `params_array` field in `struct kunit`. This will allow the parameterized test context to have direct storage of the parameter array, enabling features like using dynamic parameter arrays or using context beyond just the previous parameter. This will also enable outputting the KTAP test plan for a parameterized test when the parameter count is available. Patches 5 and 6 add examples tests to lib/kunit/kunit-example-test.c to showcase the new features and patch 7 updates the KUnit documentation to reflect all the framework changes.

[PATCH v2 00/19] rust: replace `kernel::c_str!` with C-Strings
