2024-07-16Merge tag 'sysctl-6.11-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl Pull sysctl updates from Joel Granados: - Remove "->procname == NULL" check when iterating through sysctl table arrays Removing sentinels in ctl_table arrays reduces the build time size and runtime memory consumed by ~64 bytes per array. With all ctl_table sentinels gone, the additional check for ->procname == NULL that worked in tandem with the ARRAY_SIZE to calculate the size of the ctl_table arrays is no longer needed and has been removed. The sysctl register functions now returns an error if a sentinel is used. - Preparation patches for sysctl constification Constifying ctl_table structs prevents the modification of proc_handler function pointers as they would reside in .rodata. The ctl_table arguments in sysctl utility functions are const qualified in preparation for a future treewide proc_handler argument constification commit. - Misc fixes Increase robustness of set_ownership by providing sane default ownership values in case the callee doesn't set them. Bound check proc_dou8vec_minmax to avoid loading buggy modules and give sysctl testing module a name to avoid compiler complaints. * tag 'sysctl-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl: sysctl: Warn on an empty procname element sysctl: Remove ctl_table sentinel code comments sysctl: Remove "child" sysctl code comments sysctl: Remove superfluous empty allocations from sysctl internals sysctl: Replace nr_entries with ctl_table_size in new_links sysctl: Remove check for sentinel element in ctl_table arrays mm profiling: Remove superfluous sentinel element from ctl_table locking: Remove superfluous sentinel element from kern_lockdep_table sysctl: Add module description to sysctl-testing sysctl: constify ctl_table arguments of utility function utsname: constify ctl_table arguments of utility function sysctl: move the extra1/2 boundary check of u8 to sysctl_check_table_array sysctl: always initialize i_uid/i_gid

git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi Pull EFI updates from Ard Biesheuvel: "Note the removal of the EFI fake memory map support - this is believed to be unused and no longer worth supporting. However, we could easily bring it back if needed. With recent developments regarding confidential VMs and unaccepted memory, combined with kexec, creating a known inaccurate view of the firmware's memory map and handing it to the OS is a feature we can live without, hence the removal. Alternatively, I could imagine making this feature mutually exclusive with those confidential VM related features, but let's try simply removing it first. Summary: - Drop support for the 'fake' EFI memory map on x86 - Add an SMBIOS based tweak to the EFI stub instructing the firmware on x86 Macbook Pros to keep both GPUs enabled - Replace 0-sized array with flexible array in EFI memory attributes table handling - Drop redundant BSS clearing when booting via the native PE entrypoint on x86 - Avoid returning EFI_SUCCESS when aborting on an out-of-memory condition - Cosmetic tweak for arm64 KASLR loading logic" * tag 'efi-next-for-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: efi: Replace efi_memory_attributes_table_t 0-sized array with flexible array efi: Rename efi_early_memdesc_ptr() to efi_memdesc_ptr() arm64/efistub: Clean up KASLR logic x86/efistub: Drop redundant clearing of BSS x86/efistub: Avoid returning EFI_SUCCESS on error x86/efistub: Call Apple set_os protocol on dual GPU Intel Macs x86/efistub: Enable SMBIOS protocol handling for x86 efistub/smbios: Simplify SMBIOS enumeration API x86/efi: Drop support for fake EFI memory maps

Pull SoC dt updates from Arnd Bergmann: "The devicetree updates are fairly well spread out across platforms, with Qualcomm making up about a third of the total. There are three new SoCs in existing product families this: - NXP i.MX95 is a variant of i.MX93, now with six Cortex-A55 cores instead of just two as well as a GPU and more high-speed I/O devices. - Qualcomm QCS8550 is a variant of SM8550 for IOT devices - Airoha EN7581 is a 10G-PON network chip and related to the MT7981 Wireless router chip from its parent Mediatek. In total there are 58 new machines, including four riscv boards and eight for 32-bit arm. The most exciting new addition is probably a pair of laptops based on the Qualcomm x1e80100 (Snapdragon X1 Elite) chip, the Asus Vivobook S15 and the Lenovo Yoga Slim7x. Other noteworthy new additions are: - A total of 20 Qualcomm based machines, mostly Android devices from Samsung, Motorola and LG, as well as a wireless router and some reference designs - Six NXP i.MX based machines, mostly industrial boards along with some reference designs - Mediatek sees some interesting Filogic based routers including the "OpenWRT One", a few new Chromebooks as well as single-board computers. - Four machines from Solidrun based on Marvell cn913x, replacing the older Armada 8000 based counterparts - The four Amlogic machines are all set top boxes or reference designs for them - The nine new Rockchips machines are mostly single-board computers including some interesting ones based on the rk3588 chip like the ROCK 5 ITX board and the CM3588 with its four NVMe slots - The RISC-V boards are all single-board computers based on Starfive JH7110, Microchip MPFS and Allwinner D1, which all had similar boards already There are also a lot of updates to already supported machines, notably for the TI K3, Rockchips, Freescale and of course Qualcomm platforms" * tag 'soc-dt-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (846 commits) arm64: dts: allwinner: h616: add crypto engine node riscv: dts: add clock generator for Sophgo SG2042 SoC arm64: dts: rockchip: Add Xunlong Orange Pi 3B dt-bindings: arm: rockchip: Add Xunlong Orange Pi 3B arm64: dts: rockchip: Add Radxa ROCK 3B dt-bindings: arm: rockchip: Add Radxa ROCK 3B mailmap: Update Luca Weiss's email address ARM: dts: ixp4xx: nslu2: beeper uses PWM arm64: dts: rockchip: add ROCK 5 ITX board dt-bindings: arm: rockchip: Add ROCK 5 ITX board arm64: dts: rockchip: Add dma-names to uart1 on Pine64 rk3566 devices arm64: dts: rockchip: Add avdd supplies to hdmi on rock64 arm64: dts: qcom: msm8916-lg-c50: add initial dts for LG Leon LTE arm64: dts: qcom: msm8916-lg-m216: Add initial device tree dt-bindings: arm: qcom: Add msm8916 based LG devices ARM: dts: qcom: msm8960: correct memory base arm64: dts: qcom: ipq9574: Add icc provider ability to gcc dt-bindings: interconnect: Add Qualcomm IPQ9574 support arm64: dts: qcom: sm8150: Add video clock controller node arm64: dts: qcom: pm6150: Add vibrator ...

2024-07-16docs: maintainer: discourage taking conversations off-listJakub Kicinski
Multiple vendors seem to prefer taking discussions off list, and ask contributors to work with them privately rather than just send patches to the list. I'd imagine this is because it's hard to fit in time for random developers popping up with features to review into packed schedule. From what I've seen "work in private" usually means someone on the company side will be assigned to handle the interaction, possibly months later. In worst case, the person scheduled to help the contributor takes over and writes the code themselves. This is not how the community is supposed to work.

2024-07-16Merge branch 'kvm-6.11-sev-attestation' into HEADPaolo Bonzini
The GHCB 2.0 specification defines 2 GHCB request types to allow SNP guests to send encrypted messages/requests to firmware: SNP Guest Requests and SNP Extended Guest Requests. These encrypted messages are used for things like servicing attestation requests issued by the guest. Implementing support for these is required to be fully GHCB-compliant. For the most part, KVM only needs to handle forwarding these requests to firmware (to be issued via the SNP_GUEST_REQUEST firmware command defined in the SEV-SNP Firmware ABI), and then forwarding the encrypted response to the guest. However, in the case of SNP Extended Guest Requests, the host is also able to provide the certificate data corresponding to the endorsement key used by firmware to sign attestation report requests. This certificate data is provided by userspace because: 1) It allows for different keys/key types to be used for each particular guest with requiring any sort of KVM API to configure the certificate table in advance on a per-guest basis. 2) It provides additional flexibility with how attestation requests might be handled during live migration where the certificate data for source/dest might be different. 3) It allows all synchronization between certificates and firmware/signing key updates to be handled purely by userspace rather than requiring some in-kernel mechanism to facilitate it. [1] To support fetching certificate data from userspace, a new KVM exit type will be needed to handle fetching the certificate from userspace. An attempt to define a new KVM_EXIT_COCO/KVM_EXIT_COCO_REQ_CERTS exit type to handle this was introduced in v1 of this patchset, but is still being discussed by community, so for now this patchset only implements a stub version of SNP Extended Guest Requests that does not provide certificate data, but is still enough to provide compliance with the GHCB 2.0 spec.
2024-07-16KVM: SEV: Provide support for SNP_EXTENDED_GUEST_REQUEST NAE eventMichael Roth
Version 2 of GHCB specification added support for the SNP Extended Guest Request Message NAE event. This event serves a nearly identical purpose to the previously-added SNP_GUEST_REQUEST event, but for certain message types it allows the guest to supply a buffer to be used for additional information in some cases. Currently the GHCB spec only defines extended handling of this sort in the case of attestation requests, where the additional buffer is used to supply a table of certificate data corresponding to the attestion report's signing key. Support for this extended handling will require additional KVM APIs to handle coordinating with userspace. Whether or not the hypervisor opts to provide this certificate data is optional. However, support for processing SNP_EXTENDED_GUEST_REQUEST GHCB requests is required by the GHCB 2.0 specification for SNP guests, so for now implement a stub implementation that provides an empty certificate table to the guest if it supplies an additional buffer, but otherwise behaves identically to SNP_GUEST_REQUEST.

sev_guest.h currently contains various definitions relating to the format of SNP_GUEST_REQUEST commands to SNP firmware. Currently only the sev-guest driver makes use of them, but when the KVM side of this is implemented there's a need to parse the SNP_GUEST_REQUEST header to determine whether additional information needs to be provided to the guest. Prepare for this by moving those definitions to a common header that's shared by host/guest code so that KVM can also make use of them.

2024-07-16KVM: SEV: Provide support for SNP_GUEST_REQUEST NAE eventBrijesh Singh
Version 2 of GHCB specification added support for the SNP Guest Request Message NAE event. The event allows for an SEV-SNP guest to make requests to the SEV-SNP firmware through the hypervisor using the SNP_GUEST_REQUEST API defined in the SEV-SNP firmware specification. This is used by guests primarily to request attestation reports from firmware. There are other request types are available as well, but the specifics of what guest requests are being made generally does not affect how they are handled by the hypervisor, which only serves as a proxy for the guest requests and firmware responses. Implement handling for these events. When an SNP Guest Request is issued, the guest will provide its own request/response pages, which could in theory be passed along directly to firmware. However, these pages would need special care: - Both pages are from shared guest memory, so they need to be protected from migration/etc. occurring while firmware reads/writes to them. At a minimum, this requires elevating the ref counts and potentially needing an explicit pinning of the memory. This places additional restrictions on what type of memory backends userspace can use for shared guest memory since there would be some reliance on using refcounted pages. - The response page needs to be switched to Firmware-owned state before the firmware can write to it, which can lead to potential host RMP #PFs if the guest is misbehaved and hands the host a guest page that KVM is writing to for other reasons (e.g. virtio buffers). Both of these issues can be avoided completely by using separately-allocated bounce pages for both the request/response pages and passing those to firmware instead. So that's the approach taken here.

Replace the deprecated[1] uses of strncpy() in tcp_ca_get_name_by_key() and tcp_get_default_congestion_control(). The callers use the results as standard C strings (via nla_put_string() and proc handlers respectively), so trailing padding is not needed. Since passing the destination buffer arguments decays it to a pointer, the size can't be trivially determined by the compiler. ca->name is the same length in both cases, so strscpy() won't fail (when ca->name is NUL-terminated). Include the length explicitly instead of using the 2-argument strscpy().

2024-07-16KVM: x86: Suppress MMIO that is triggered during task switch emulationSean Christopherson
Explicitly suppress userspace emulated MMIO exits that are triggered when emulating a task switch as KVM doesn't support userspace MMIO during complex (multi-step) emulation. Silently ignoring the exit request can result in the WARN_ON_ONCE(vcpu->mmio_needed) firing if KVM exits to userspace for some other reason prior to purging mmio_needed. See commit 0dc902267cb3 ("KVM: x86: Suppress pending MMIO write exits if emulator detects exception") for more details on KVM's limitations with respect to emulated MMIO during complex emulator flows.

2024-07-16KVM: x86/mmu: Clean up make_huge_page_split_spte() definition and introSean Christopherson
Tweak the definition of make_huge_page_split_spte() to eliminate an unnecessarily long line, and opportunistically initialize child_spte to make it more obvious that the child is directly derived from the huge parent. No functional change intended. Signed-off-by: Sean Christopherson <seanjc@google.com> Message-ID: <20240712151335.1242633-3-seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2024-07-16KVM: x86/mmu: Bug the VM if KVM tries to split a !hugepage SPTESean Christopherson
Bug the VM instead of simply warning if KVM tries to split a SPTE that is non-present or not-huge. KVM is guaranteed to end up in a broken state as the callers fully expect a valid SPTE, e.g. the shadow MMU will add an rmap entry, and all MMUs will account the expected small page. Returning '0' is also technically wrong now that SHADOW_NONPRESENT_VALUE exists, i.e. would cause KVM to create a potential #VE SPTE. While it would be possible to have the callers gracefully handle failure, doing so would provide no practical value as the scenario really should be impossible, while the error handling would add a non-trivial amount of noise.
