[PATCH] selftests/net: fix unused return value warnings in ksft.h

[PATCH bpf-next 0/5] selftests/bpf: Extend sockmap_redir to test no-redir SK_DROP/SK_PASS

sockmap_redir was introduced to comprehensively test the BPF redirection.

[PATCH v1] selftests/mm: gup_tests: option to GUP all pages in a single call

by David Hildenbrand

We recently missed detecting an issue during early testing because the default (!all) tests would not trigger it and even when running "all" tests it only would happen sometimes because of races. So let's allow for an easy way to specify "GUP all pages in a single call", extend the test matrix and extend our default (!all) tests. By GUP'ing all pages in a single call, with the default size of 128MiB we'll cover multiple leaf page tables / PMDs on architectures with sane THP sizes.

As of v6.8 commit 7fbb5e188248 ("mm: remove VM_EXEC requirement for THP eligibility") thp collapse no longer requires file-backed mappings be created with PROT_EXEC.

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 net 0/3] mptcp: misc fixes for v6.17-rc6

by Matthieu Baerts (NGI0)

Here are various unrelated fixes: - Patch 1: Fix a wrong attribute type in the MPTCP Netlink specs. A fix for v6.7. - Patch 2: Avoid mentioning a deprecated MPTCP sysctl knob in the doc. A fix for v6.15. - Patch 3: Handle new warnings from ShellCheck v0.11.0. This prevents some warnings reported by some CIs. If it is not a good material for 'net', please drop it and I can resend it later, targeting 'net-next'.
