[PATCH v3 0/2] memcg: Fix test_memcg_min/low test failures

by Waiman Long

v3: - Take up Johannes' suggestion of just skip the !usage case and fix test_memcontrol selftest to fix the rests of the min/low failures. The test_memcontrol selftest consistently fails its test_memcg_low sub-test and sporadically fails its test_memcg_min sub-test. This patchset fixes the test_memcg_min and test_memcg_low failures by skipping the !usage case in shrink_node_memcgs() and adjust the test_memcontrol selftest to fix other causes of the test failures. Note that I decide not to use the suggested mem_cgroup_usage() call as it is a real function call defined in mm/memcontrol.c which is not available if CONFIG_MEMCG isn't defined.

[PATCH RESEND] kunit: qemu_configs: SH: Respect kunit cmdline

by Thomas Weißschuh

The default SH kunit configuration sets CONFIG_CMDLINE_OVERWRITE which completely disregards the cmdline passed from the bootloader/QEMU in favor of the builtin CONFIG_CMDLINE. However the kunit tool needs to pass arguments to the in-kernel kunit core, for filters and other runtime parameters. Enable CONFIG_CMDLINE_EXTEND instead, so kunit arguments are respected.

[PATCH] kunit: cs_dsp: Depend on FW_CS_DSP rather then enabling it

They come as part > of an SoC. "Yes and no. The problem is that the EP implementation is meant to be a generic library and while GIC-ITS guarantees immutability of the address/data pair after setup, there are architectures (x86, loongson, riscv) where the base MSI controller does not and immutability is only achieved when interrupt remapping is enabled. The latter can be disabled at boot-time and then the EP implementation becomes a lottery across affinity changes. That was my concern about this library implementation and that's why I asked for a mechanism to ensure that the underlying irqdomain provides a immutable address/data pair. So it does not matter for GIC-ITS, but in the larger picture it matters. Thanks, tglx " So it does not matter for GIC-ITS, but in the larger picture it matters. - Link to v15: https://lore.kernel.org/r/20250211-ep-msi-v15-0-bcacc1f2b1a9@nxp.com Changes in v15: - rebase to v6.14-rc1 - fix build issue find by kernel test robot - Link to v14: https://lore.kernel.org/r/20250207-ep-msi-v14-0-9671b136f2b8@nxp.com Changes in v14: Marc Zyngier raised concerns about adding DOMAIN_BUS_DEVICE_PCI_EP_MSI. As a result, the approach has been reverted to the v9 method. However, there are several improvements: MSI now supports msi-map in addition to msi-parent. - The struct device: id is used as the endpoint function (EPF) device identity to map to the stream ID (sideband information). - The EPC device tree source (DTS) utilizes msi-map to provide such information. - The EPF device's of_node is set to the EPC controller’s node. This approach is commonly used for multi-function device (MFD) platform child devices, allowing them to inherit properties from the MFD device’s DTS, such as reset-cells and gpio-cells. This method is well-suited for the current case, as the EPF is inherently created/binded to the EPC and should inherit the EPC’s DTS node properties. Additionally: Since the basic IMX95 LUT support has already been merged into the mainline, a DTS and driver increment patch is added to complete the solution. The patch is rebased onto the latest linux-next tree and aligned with the new pcitest framework. - Link to v13: https://lore.kernel.org/r/20241218-ep-msi-v13-0-646e2192dc24@nxp.com Changes in v13: - Change to use DOMAIN_BUS_PCI_DEVICE_EP_MSI - Change request id as func | vfunc << 3 - Remove IRQ_DOMAIN_MSI_IMMUTABLE Thomas Gleixner: I hope capture all your points in review comments.

[PATCH] selftests: Removing deprecated strncpy()

by Kevin Paul Reddy Janagari

This patch suggests the replacement of strncpy with strscpy as per Documentation/process/deprecated. The strncpy() fails to guarantee NULL termination, The function adds zero pads which isn't really convenient for short strings as it may cause performance issues. strscpy() is a preferred replacement because it overcomes the limitations of strncpy mentioned above.

[PATCH 0/4] sysctl: Move the u8 range check test to lib/test_sysctl.c

by Joel Granados

Originally introduced to sysctl-test.c by commit b5ffbd139688 ("sysctl: move the extra1/2 boundary check of u8 to sysctl_check_table_array"), it has been shown to lead to a panic under certain conditions related to a dangling registration. This series moves the u8 test to lib/test_sysctl.c where the registration calls are kept and correctly removed on module exit. An additional 0012 test is added to selftests/sysctl/sysctl.sh in order to visualize the registration calls done in test_sysctl.c. Very much related to adding tests to sysctl, the last two patches of this series reduce the places that need to be changed when tests are added by managing the initialization and closing of sysctl tables with a for loop. Comments are greatly appreciated Signed-off-by: Joel Granados <joel.granados(a)kernel.org> --- Joel Granados (4): sysctl: move u8 register test to lib/test_sysctl.c sysctl: Add 0012 to test the u8 range check sysctl: call sysctl tests with a for loop sysctl: Close test ctl_headers with a for loop kernel/sysctl-test.c | 49 ------------ lib/test_sysctl.c | 133 +++++++++++++++++++++---------- tools/testing/selftests/sysctl/sysctl.sh | 30 +++++++ 3 files changed, 122 insertions(+), 90 deletions(-) --- base-commit: 7eb172143d5508b4da468ed59ee857c6e5e01da6 change-id: 20250321-jag-test_extra_val-40954050a1f6 Best regards, -- Joel Granados <joel.granados(a)kernel.org>
