hwmon: (ina238) Report energy in microjoules

2025-07-18T16:50:51Z

The hwmon sysfs interface specifies that energy values should be reported in microjoules. This is also what tools such as lmsensors expect, reporting wrong values otherwise. Adjust the driver to scale the output accordingly and adjust ina238 driver documentation.

Pull networking fixes from Jakub Kicinski: "Including fixes from Bluetooth, CAN, WiFi and Netfilter. More code here than I would have liked. That said, better now than next week. Nothing particularly scary stands out. The improvement to the OpenVPN input validation is a bit large but better get them in before the code makes it to a final release. Some of the changes we got from sub-trees could have been split better between the fix and -next refactoring, IMHO, that has been communicated. We have one known regression in a TI AM65 board not getting link. The investigation is going a bit slow, a number of people are on vacation.

KVM TDX fixes for 6.16 - Fix a formatting goof in the TDX documentation. - Reject KVM_SET_TSC_KHZ for guests with a protected TSC (currently only TDX). - Ensure struct kvm_tdx_capabilities fields that are not explicitly set by KVM are zeroed.

ovpn: reject unexpected netlink attributes

2025-07-16T09:51:30Z

Netlink ops do not expect all attributes to be always set, however this condition is not explicitly coded any where, leading the user to believe that all sent attributes are somewhat processed. Fix this behaviour by introducing explicit checks. For CMD_OVPN_PEER_GET and CMD_OVPN_KEY_GET directly open-code the needed condition in the related ops handlers. While for all other ops use attribute subsets in the ovpn.yaml spec file.

KVM: Documentation: document how KVM is tested

2025-07-15T17:32:18Z

Proper testing greatly simplifies both patch development and review, but it can be unclear what kind of userspace or guest support should accompany new features. Clarify maintainer expectations in terms of testing expectations; additionally, list the cases in which open-source userspace support is pretty much a necessity and its absence can only be mitigated by selftests. While these ideas have long been followed implicitly by KVM contributors and maintainers, formalize them in writing to provide consistent (though not universal) guidelines.
