Pull KVM fixes from Paolo Bonzini:
"Many patches, pretty much all of them small, that accumulated while I
was on vacation.
ARM:
- Remove the last leftovers of the ill-fated FPSIMD host state
mapping at EL2 stage-1
- Fix unexpected advertisement to the guest of unimplemented S2 base
granule sizes
- Gracefully fail initialising pKVM if the interrupt controller isn't
GICv3
- Also gracefully fail initialising pKVM if the carveout allocation
fails
- Fix the computing of the minimum MMIO range required for the host
on stage-2 fault
- Fix the generation of the GICv3 Maintenance Interrupt in nested
mode
x86:
- Reject SEV{-ES} intra-host migration if one or more vCPUs are
actively being created, so as not to create a non-SEV{-ES} vCPU in
an SEV{-ES} VM
- Use a pre-allocated, per-vCPU buffer for handling de-sparsification
of vCPU masks in Hyper-V hypercalls; fixes a "stack frame too
large" issue
- Allow out-of-range/invalid Xen event channel ports when configuring
IRQ routing, to avoid dictating a specific ioctl() ordering to
userspace
- Conditionally reschedule when setting memory attributes to avoid
soft lockups when userspace converts huge swaths of memory to/from
private
- Add back MWAIT as a required feature for the MONITOR/MWAIT selftest
- Add a missing field in struct sev_data_snp_launch_start that
resulted in the guest-visible workarounds field being filled at the
wrong offset
- Skip non-canonical address when processing Hyper-V PV TLB flushes
to avoid VM-Fail on INVVPID
- Advertise supported TDX TDVMCALLs to userspace
- Pass SetupEventNotifyInterrupt arguments to userspace
- Fix TSC frequency underflow"

netlink: specs: mptcp: replace underscores with dashes in names
We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen, if used, replaces special
chars in names) but it gives more uniform naming in Python.

ublk: fix narrowing warnings in UAPI header
When a C++ file compiled with -Wc++11-narrowing includes the UAPI header
linux/ublk_cmd.h, ublk_sqe_addr_to_auto_buf_reg()'s assignments of u64

KVM: TDX: Exit to userspace for GetTdVmCallInfo
Exit to userspace for TDG.VP.VMCALL<GetTdVmCallInfo> via KVM_EXIT_TDX, to allow userspace to provide information about the support of TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API. GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>, <ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>, <Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and <Instruction.WRMSR>. They must be supported by VMM to support TDX guests. For GetTdVmCallInfo - When leaf (r12) to enumerate TDVMCALL functionality is set to 0, successful execution indicates all GHCI base TDVMCALLs listed above are supported. Update the KVM TDX document with the set of the GHCI base APIs. - When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it indicates the TDX guest is querying the supported TDVMCALLs beyond the GHCI base TDVMCALLs. Exit to userspace to let userspace set the TDVMCALL sub-function bit(s) accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s) supported by itself when the TDVMCALLs don't need support from userspace after returning from userspace and before entering guest. Currently, no such TDVMCALLs implemented, KVM just sets the values returned from userspace.

KVM: TDX: Handle TDG.VP.VMCALL<GetQuote>
Handle TDVMCALL for GetQuote to generate a TD-Quote. GetQuote is a doorbell-like interface used by TDX guests to request VMM to generate a TD-Quote signed by a service hosting TD-Quoting Enclave operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in a shared-memory area as parameter. Host VMM can access it and queue the operation for a service hosting TD-Quoting enclave. When completed, the Quote is returned via the same shared-memory area. KVM only checks the GPA from the TDX guest has the shared-bit set and drops the shared-bit before exiting to userspace to avoid bleeding the shared-bit into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU) and userspace VMM queues the operation asynchronously. KVM sets the return code according to the 'ret' field set by userspace to notify the TDX guest whether the request has been queued successfully or not. When the request has been queued successfully, the TDX guest can poll the status field in the shared-memory area to check whether the Quote generation is completed or not. When completed, the generated Quote is returned via the same buffer. Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is required to handle the KVM exit reason as the initial support for TDX, by reentering KVM to ensure that the TDVMCALL is complete. While at it, add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.

net: ethtool: remove duplicate defines for family info
Commit under fixes switched to uAPI generation from the YAML
spec. A number of custom defines were left behind, mostly
for commands very hard to express in YAML spec.
Among what was left behind was the name and version of
the generic netlink family. Problem is that the codegen
always outputs those values so we ended up with a duplicated,
differently named set of defines.
Provide naming info in YAML and remove the incorrect defines.

Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt changes for 6.16-rc1.
Included in here are the following:
- USB offload support for audio devices.
I think this takes the record for the most number of patch series
(30+) over the longest period of time (2+ years) to get merged
properly.
Many props go to Wesley Cheng for seeing this effort through, they
took a major out-of-tree hacked-up-monstrosity that was created by
multiple vendors for their specific devices, got it all merged into
a semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees.
This feature offers major power savings on embedded devices where a
USB audio stream can continue to flow while the rest of the system
is sleeping, something that devices running on battery power really
care about. There are still some more small tweaks left to be done
here, and those patches are still out for review and arguing among
the different hardware companies, but this is a major step forward
and a great example of how to do upstream development well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added
for the USB offload feature.
- lots of little updates and fixes in different drivers
All of these have been in linux-next for over 2 weeks, the USB offload
logic has been in there for 8 weeks now, with no reported issues"

drm/xe/pxp: Clarify PXP queue creation behavior if PXP is not ready
The expected flow of operations when using PXP is to query the PXP status and wait for it to transition to "ready" before attempting to create an exec_queue. This flow is followed by the Mesa driver, but there is no guarantee that an incorrectly coded (or malicious) app will not attempt to create the queue first without querying the status. Therefore, we need to clarify what the expected behavior of the queue creation ioctl is in this scenario. Currently, the ioctl always fails with an -EBUSY code no matter the error, but for consistency it is better to distinguish between "failed to init" (-EIO) and "not ready" (-EBUSY), the same way the query ioctl does. Note that, while this is a change in the return code of an ioctl, the behavior of the ioctl in this particular corner case was not clearly spec'd, so no one should have been relying on it (and we know that Mesa, which is the only known userspace for this, didn't). v2: Minor rework of the doc (Rodrigo) Fixes: |

Merge tag 'pci-v6.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)
- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)
Resource management:
- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)
- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)
- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)
- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)
Error handling:
- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)
- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)
- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)
- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)
Power management:
- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)
- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)
Power control:
- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)
- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)
Bandwidth control:
- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)
- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)
PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)
Virtualization:
- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)
Endpoint framework:
- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)
- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)
- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)
- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)
- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:
- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)
- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)
- Skip ports disabled in DT when setting up ports (Janne Grunau)
- Add t6020 compatible string (Alyssa Rosenzweig)
- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)
Cadence PCIe controller driver:
- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)
- Make the cadence core buildable as a module (Kishon Vijay Abraham I)
- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)
Freescale i.MX6 PCIe controller driver:
- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)
Mobiveil PCIe controller driver:
- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)
NVIDIA Tegra194 PCIe controller driver:
- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)
Qualcomm PCIe controller driver:
- Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
equalization presets (Krishna Chaitanya Chundru)
- Read Maximum Link Width from the Link Capabilities register if DT
lacks 'num-lanes' property (Krishna Chaitanya Chundru)
- Add Physical Layer 64 GT/s Capability ID and register offsets for
8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
Chundru)
- Add generic dwc support for configuring lane equalization presets
(Krishna Chaitanya Chundru)
- Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)
Renesas R-Car PCIe controller driver:
- Describe endpoint BAR 4 as being fixed size (Jerome Brunet)
- Document how to obtain R-Car V4H (r8a779g0) controller firmware
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)
- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)
Rockchip DesignWare PCIe controller driver:
- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)
- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)
- Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
resets non-sticky registers (Shawn Lin)
- Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
(Diederik de Haas)
Synopsys DesignWare PCIe controller driver:
- Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
more robust; this will not affect the intended link width if all
lanes are functional (Wenbin Yao)
- Return bool (not int) for link-up check in dw_pcie_ops.link_up()
and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
tegra194, uniphier, visconti (Hans Zhang)
- Add debugfs support for exposing DWC device-specific PTM context
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Make j721e buildable as a loadable and removable module (Siddharth
Vadapalli)
- Fix j721e host/endpoint dependencies that result in link failures
in some configs (Arnd Bergmann)
Device tree bindings:
- Add qcom DT binding for 'global' interrupt (PCIe controller and
link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan
Sadhasivam)
- Add qcom DT binding for 8 MSI SPI interrupts for msm8998, ipq8074,
ipq8074-gen3, ipq6018 (Manivannan Sadhasivam)
- Add dw rockchip DT binding for rk3576 and rk3562 (Kever Yang)
- Correct indentation and style of examples in brcm,stb-pcie,
cdns,cdns-pcie-ep, intel,keembay-pcie-ep, intel,keembay-pcie,
microchip,pcie-host, rcar-pci-ep, rcar-pci-host, xilinx-versal-cpm
(Krzysztof Kozlowski)

and IPQ9574 (Varadarajan Narayanan)
- Convert v3,v360epc-pci from text to DT schema binding (Rob Herring)
- Change microchip,pcie-host DT binding to be 'dma-noncoherent' since
PolarFire may be configured that way (Conor Dooley)
Miscellaneous:
- Drop 'pci' suffix from intel_mid_pci.c filename to match similar
files (Andy Shevchenko)
- All platforms with PCI have an MMU, so add PCI Kconfig dependency
on MMU to simplify build testing and avoid inadvertent build
regressions (Arnd Bergmann)

Pull fuse updates from Miklos Szeredi: - Remove tmp page copying in writeback path (Joanne). This removes ~300 lines and with that a lot of complexity related to avoiding reclaim related deadlock. The old mechanism is replaced with a mapping flag that tells the MM not to block reclaim waiting for writeback to complete. The MM parts have been reviewed/acked by respective maintainers. - Convert more code to handle large folios (Joanne). This still just adds the code to deal with large folios and does not enable them yet. - Allow invalidating all cached lookups atomically (Luis Henriques).

Pull MM updates from Andrew Morton: - "Add folio_mk_pte()" from Matthew Wilcox simplifies the act of creating a pte which addresses the first page in a folio and reduces the amount of plumbing which architecture must implement to provide this. - "Misc folio patches for 6.16" from Matthew Wilcox is a shower of largely unrelated folio infrastructure changes which clean things up and better prepare us for future work. - "memory,x86,acpi: hotplug memory alignment advisement" from Gregory Price adds early-init code to prevent x86 from leaving physical memory unused when physical address regions are not aligned to memory block size. - "mm/compaction: allow more aggressive proactive compaction" from Michal Clapinski provides some tuning of the (sadly, hard-coded (more sadly, not auto-tuned)) thresholds for our invokation of proactive compaction. In a simple test case, the reduction of a guest VM's memory consumption was dramatic. - "Minor cleanups and improvements to swap freeing code" from Kemeng Shi provides some code cleaups and a small efficiency improvement to this part of our swap handling code. - "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin adds the ability for a ptracer to modify syscalls arguments. At this time we can alter only "system call information that are used by strace system call tampering, namely, syscall number, syscall arguments, and syscall return value. This series should have been incorporated into mm.git's "non-MM" branch, but I goofed. - "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl against /proc/pid/pagemap.

This might be needed when 128-bit Page Table Descriptors are enabled for ARM. - "Always call constructor for kernel page tables" from Kevin Brodsky ensures that the ctor/dtor is always called for kernel pgtables, as it already is for user pgtables. This permits the addition of more functionality such as "insert hooks to protect page tables". This change does result in various architectures performing unnecesary work, but this is fixed up where it is anticipated to occur. - "Rust support for mm_struct, vm_area_struct, and mmap" from Alice Ryhl adds plumbing to permit Rust access to core MM structures. - "fix incorrectly disallowed anonymous VMA merges" from Lorenzo Stoakes takes advantage of some VMA merging opportunities which we've been missing for 15 years. - "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from SeongJae Park optimizes process_madvise()'s TLB flushing. Instead of flushing each address range in the provided iovec, we batch the flushing across all the iovec entries. The syscall's cost was approximately halved with a microbenchmark which was designed to load this particular operation. - "Track node vacancy to reduce worst case allocation counts" from Sidhartha Kumar makes the maple tree smarter about its node preallocation. stress-ng mmap performance increased by single-digit percentages and the amount of unnecessarily preallocated memory was dramaticelly reduced. - "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes a few unnecessary things which Baoquan noted when reading the code. - ""Enhance sysfs handling for memory hotplug in weighted interleave" from Rakie Kim "enhances the weighted interleave policy in the memory management subsystem by improving sysfs handling, fixing memory leaks, and introducing dynamic sysfs updates for memory hotplug support".

ublk: have a per-io daemon instead of a per-queue daemon
Currently, ublk_drv associates to each hardware queue (hctx) a unique task (called the queue's ubq_daemon) which is allowed to issue COMMIT_AND_FETCH commands against the hctx. If any other task attempts to do so, the command fails immediately with EINVAL. When considered together with the block layer architecture, the result is that for each CPU C on the system, there is a unique ublk server thread which is allowed to handle I/O submitted on CPU C. This can lead to suboptimal performance under imbalanced load generation. For an extreme example, suppose all the load is generated on CPUs mapping to a single ublk server thread. Then that thread may be fully utilized and become the bottleneck in the system, while other ublk server threads are totally idle. This issue can also be addressed directly in the ublk server without kernel support by having threads dequeue I/Os and pass them around to ensure even load. But this solution requires inter-thread communication at least twice for each I/O (submission and completion), which is generally a bad pattern for performance. The problem gets even worse with zero copy, as more inter-thread communication would be required to have the buffer register/unregister calls to come from the correct thread. Therefore, address this issue in ublk_drv by allowing each I/O to have its own daemon task. Two I/Os in the same queue are now allowed to be serviced by different daemon tasks - this was not possible before. Imbalanced load can then be balanced across all ublk server threads by having the ublk server threads issue FETCH_REQs in a round-robin manner. As a small toy example, consider a system with a single ublk device having 2 queues, each of depth 4. A ublk server having 4 threads could issue its FETCH_REQs against this device as follows (where each entry is the qid,tag pair that the FETCH_REQ targets): ublk server thread: T0 T1 T2 T3 0,0 0,1 0,2 0,3 1,3 1,0 1,1 1,2 This setup allows for load that is concentrated on one hctx/ublk_queue to be spread out across all ublk server threads, alleviating the issue described above. Add the new UBLK_F_PER_IO_DAEMON feature to ublk_drv, which ublk servers can use to essentially test for the presence of this change and tailor their behavior accordingly.

bpf: Fix L4 csum update on IPv6 in CHECKSUM_COMPLETE
In Cilium, we use bpf_csum_diff + bpf_l4_csum_replace to, among other
things, update the L4 checksum after reverse SNATing IPv6 packets. That
use case is however not currently supported and leads to invalid
skb->csum values in some cases. This patch adds support for IPv6 address
changes in bpf_l4_csum_update via a new flag.
When calling bpf_l4_csum_replace in Cilium, it ends up calling
inet_proto_csum_replace_by_diff:
1: void inet_proto_csum_replace_by_diff(__sum16 *sum, struct sk_buff *skb,
2: __wsum diff, bool pseudohdr)
3: {
4: if (skb->ip_summed != CHECKSUM_PARTIAL) {
5: csum_replace_by_diff(sum, diff);
6: if (skb->ip_summed == CHECKSUM_COMPLETE && pseudohdr)
7: skb->csum = ~csum_sub(diff, skb->csum);
8: } else if (pseudohdr) {
9: *sum = ~csum_fold(csum_add(diff, csum_unfold(*sum)));
10: }
11: }
The bug happens when we're in the CHECKSUM_COMPLETE state. We've just
updated one of the IPv6 addresses. The helper now updates the L4 header
checksum on line 5. Next, it updates skb->csum on line 7. It shouldn't.
For an IPv6 packet, the updates of the IPv6 address and of the L4
checksum will cancel each other. The checksums are set such that
computing a checksum over the packet including its checksum will result
in a sum of 0. So the same is true here when we update the L4 checksum
on line 5. We'll update it as to cancel the previous IPv6 address
update. Hence skb->csum should remain untouched in this case.
The same bug doesn't affect IPv4 packets because, in that case, three
fields are updated: the IPv4 address, the IP checksum, and the L4
checksum. The change to the IPv4 address and one of the checksums still
cancel each other in skb->csum, but we're left with one checksum update
and should therefore update skb->csum accordingly. That's exactly what
inet_proto_csum_replace_by_diff does.
This special case for IPv6 L4 checksums is also described atop
inet_proto_csum_replace16, the function we should be using in this case.
This patch introduces a new bpf_l4_csum_replace flag, BPF_F_IPV6,
to indicate that we're updating the L4 checksum of an IPv6 packet. When
the flag is set, inet_proto_csum_replace_by_diff will skip the
skb->csum update.

"As far as x86 goes this pull request "only" includes TDX host support.
Quotes are appropriate because (at 6k lines and 100+ commits) it is
much bigger than the rest, which will come later this week and
consists mostly of bugfixes and selftests. s390 changes will also come
in the second batch.
ARM:
- Add large stage-2 mapping (THP) support for non-protected guests
when pKVM is enabled, clawing back some performance.
- Enable nested virtualisation support on systems that support it,
though it is disabled by default.
- Add UBSAN support to the standalone EL2 object used in nVHE/hVHE
and protected modes.
- Large rework of the way KVM tracks architecture features and links
them with the effects of control bits. While this has no functional
impact, it ensures correctness of emulation (the data is
automatically extracted from the published JSON files), and helps
dealing with the evolution of the architecture.
- Significant changes to the way pKVM tracks ownership of pages,
avoiding page table walks by storing the state in the hypervisor's
vmemmap. This in turn enables the THP support described above.
- New selftest checking the pKVM ownership transition rules
- Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
even if the host didn't have it.
- Fixes for the address translation emulation, which happened to be
rather buggy in some specific contexts.
- Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
from the number of counters exposed to a guest and addressing a
number of issues in the process.
- Add a new selftest for the SVE host state being corrupted by a
guest.
- Keep HCR_EL2.xMO set at all times for systems running with the
kernel at EL2, ensuring that the window for interrupts is slightly
bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
- Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
from a pretty bad case of TLB corruption unless accesses to HCR_EL2
are heavily synchronised.
- Add a per-VM, per-ITS debugfs entry to dump the state of the ITS
tables in a human-friendly fashion.
- and the usual random cleanups.
LoongArch:
- Don't flush tlb if the host supports hardware page table walks.
- Add KVM selftests support.
RISC-V:
- Add vector registers to get-reg-list selftest
- VCPU reset related improvements
- Remove scounteren initialization from VCPU reset
- Support VCPU reset from userspace using set_mpstate() ioctl
x86:
- Initial support for TDX in KVM.
This finally makes it possible to use the TDX module to run
confidential guests on Intel processors. This is quite a large
series, including support for private page tables (managed by the
TDX module and mirrored in KVM for efficiency), forwarding some
TDVMCALLs to userspace, and handling several special VM exits from
the TDX module.
This has been in the works for literally years and it's not really
possible to describe everything here, so I'll defer to the various
merge commits up to and including commit

Pull networking updates from Paolo Abeni:
"Core:
- Implement the Device Memory TCP transmit path, allowing zero-copy
data transmission on top of TCP from e.g. GPU memory to the wire.
- Move all the IPv6 routing tables management outside the RTNL scope,
under its own lock and RCU. The route control path is now 3x times
faster.
- Convert queue related netlink ops to instance lock, reducing again
the scope of the RTNL lock. This improves the control plane
scalability.
- Refactor the software crc32c implementation, removing unneeded
abstraction layers and improving significantly the related
micro-benchmarks.
- Optimize the GRO engine for UDP-tunneled traffic, for a 10%
performance improvement in related stream tests.
- Cover more per-CPU storage with local nested BH locking; this is a
prep work to remove the current per-CPU lock in local_bh_disable()
on PREMPT_RT.
- Introduce and use nlmsg_payload helper, combining buffer bounds
verification with accessing payload carried by netlink messages.
Netfilter:
- Rewrite the procfs conntrack table implementation, improving
considerably the dump performance. A lot of user-space tools still
use this interface.
- Implement support for wildcard netdevice in netdev basechain and
flowtables.
- Integrate conntrack information into nft trace infrastructure.
- Export set count and backend name to userspace, for better
introspection.
BPF:
- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops
programs and can be controlled in similar way to traditional qdiscs
using the "tc qdisc" command.
- Refactor the UDP socket iterator, addressing long standing issues
WRT duplicate hits or missed sockets.
Protocols:
- Improve TCP receive buffer auto-tuning and increase the default
upper bound for the receive buffer; overall this improves the
single flow maximum thoughput on 200Gbs link by over 60%.
- Add AFS GSSAPI security class to AF_RXRPC; it provides transport
security for connections to the AFS fileserver and VL server.
- Improve TCP multipath routing, so that the sources address always
matches the nexthop device.
- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS,
and thus preventing DoS caused by passing around problematic FDs.
- Retire DCCP socket. DCCP only receives updates for bugs, and major
distros disable it by default. Its removal allows for better
organisation of TCP fields to reduce the number of cache lines hit
in the fast path.
- Extend TCP drop-reason support to cover PAWS checks.
Driver API:
- Reorganize PTP ioctl flag support to require an explicit opt-in for
the drivers, avoiding the problem of drivers not rejecting new
unsupported flags.
- Converted several device drivers to timestamping APIs.
- Introduce per-PHY ethtool dump helpers, improving the support for
dump operations targeting PHYs.
Tests and tooling:
- Add support for classic netlink in user space C codegen, so that
ynl-c can now read, create and modify links, routes addresses and
qdisc layer configuration.
- Add ynl sub-types for binary attributes, allowing ynl-c to output
known struct instead of raw binary data, clarifying the classic
netlink output.
- Extend MPTCP selftests to improve the code-coverage.
- Add tests for XDP tail adjustment in AF_XDP.
New hardware / drivers:
- OpenVPN virtual driver: offload OpenVPN data channels processing to
the kernel-space, increasing the data transfer throughput WRT the
user-space implementation.

virtio_rtc: Add RTC class driver
Expose the virtio-rtc UTC-like clock as an RTC clock to userspace - if it is present, and if it does not step on leap seconds. The RTC class enables the virtio-rtc device to resume the system from sleep states on RTC alarm. Support RTC alarm if the virtio-rtc alarm feature is present. The virtio-rtc device signals an alarm by marking an alarmq buffer as used. Peculiarities ------------- A virtio-rtc clock is a bit special for an RTC clock in that - the clock may step (also backwards) autonomously at any time and - the device, and its notification mechanism, will be reset during boot or resume from sleep. The virtio-rtc device avoids that the driver might miss an alarm. The device signals an alarm whenever the clock has reached or passed the alarm time, and also when the device is reset (on boot or resume from sleep), if the alarm time is in the past. Open Issue ---------- The CLOCK_BOOTTIME_ALARM will use the RTC clock to wake up from sleep, and implicitly assumes that no RTC clock steps will occur during sleep. The RTC class driver does not know whether the current alarm is a real-time alarm or a boot-time alarm. Perhaps this might be handled by the driver also setting a virtio-rtc monotonic alarm (which uses a clock similar to CLOCK_BOOTTIME_ALARM). The virtio-rtc monotonic alarm would just be used to wake up in case it was a CLOCK_BOOTTIME_ALARM alarm. Otherwise, the behavior should not differ from other RTC class drivers.

virtio_rtc: Add module and driver core
Add the virtio_rtc module and driver core. The virtio_rtc module implements a driver compatible with the proposed Virtio RTC device specification. The Virtio RTC (Real Time Clock) device provides information about current time. The device can provide different clocks, e.g. for the UTC or TAI time standards, or for physical time elapsed since some past epoch. The driver can read the clocks with simple or more accurate methods. Implement the core, which interacts with the Virtio RTC device. Apart from this, the core does not expose functionality outside of the virtio_rtc module. Follow-up patches will expose PTP clocks and an RTC Class device. Provide synchronous messaging, which is enough for the expected time synchronization use cases through PTP clocks (similar to ptp_kvm) or RTC Class device.

wireguard: allowedips: add WGALLOWEDIP_F_REMOVE_ME flag
The current netlink API for WireGuard does not directly support removal of allowed ips from a peer. A user can remove an allowed ip from a peer in one of two ways: 1. By using the WGPEER_F_REPLACE_ALLOWEDIPS flag and providing a new list of allowed ips which omits the allowed ip that is to be removed. 2. By reassigning an allowed ip to a "dummy" peer then removing that peer with WGPEER_F_REMOVE_ME. With the first approach, the driver completely rebuilds the allowed ip list for a peer. If my current configuration is such that a peer has allowed ips 192.168.0.2 and 192.168.0.3 and I want to remove 192.168.0.2 the actual transition looks like this. [192.168.0.2, 192.168.0.3] <-- Initial state [] <-- Step 1: Allowed ips removed for peer [192.168.0.3] <-- Step 2: Allowed ips added back for peer This is true even if the allowed ip list is small and the update does not need to be batched into multiple WG_CMD_SET_DEVICE requests, as the removal and subsequent addition of ips is non-atomic within a single request. Consequently, wg_allowedips_lookup_dst and wg_allowedips_lookup_src may return NULL while reconfiguring a peer even for packets bound for ips a user did not intend to remove leading to unintended interruptions in connectivity. This presents in userspace as failed calls to sendto and sendmsg for UDP sockets. In my case, I ran netperf while repeatedly reconfiguring the allowed ips for a peer with wg. /usr/local/bin/netperf -H 10.102.73.72 -l 10m -t UDP_STREAM -- -R 1 -m 1024 send_data: data send error: No route to host (errno 113) netperf: send_omni: send_data failed: No route to host While this may not be of particular concern for environments where peers and allowed ips are mostly static, systems like Cilium manage peers and allowed ips in a dynamic environment where peers (i.e. Kubernetes nodes) and allowed ips (i.e. pods running on those nodes) can frequently change making WGPEER_F_REPLACE_ALLOWEDIPS problematic. The second approach avoids any possible connectivity interruptions but is hacky and less direct, requiring the creation of a temporary peer just to dispose of an allowed ip. Introduce a new flag called WGALLOWEDIP_F_REMOVE_ME which in the same way that WGPEER_F_REMOVE_ME allows a user to remove a single peer from a WireGuard device's configuration allows a user to remove an ip from a peer's set of allowed ips. This enables incremental updates to a device's configuration without any connectivity blips or messy workarounds. A corresponding patch for wg extends the existing `wg set` interface to leverage this feature. $ wg set wg0 peer <PUBKEY> allowed-ips +192.168.88.0/24,-192.168.0.1/32 When '+' or '-' is prepended to any ip in the list, wg clears WGPEER_F_REPLACE_ALLOWEDIPS and sets the WGALLOWEDIP_F_REMOVE_ME flag on any ip prefixed with '-'.

Pull locking updates from Ingo Molnar:
"Futexes:
- Add support for task local hash maps (Sebastian Andrzej Siewior,
Peter Zijlstra)
- Implement the FUTEX2_NUMA ABI, which feature extends the futex
interface to be NUMA-aware. On NUMA-aware futexes a second u32 word
containing the NUMA node is added to after the u32 futex value word
(Peter Zijlstra)
- Implement the FUTEX2_MPOL ABI, which feature extends the futex
interface to be mempolicy-aware as well, to further refine futex
node mappings and lookups (Peter Zijlstra)
Locking primitives:
- Misc cleanups (Andy Shevchenko, Borislav Petkov, Colin Ian King,
Ingo Molnar, Nam Cao, Peter Zijlstra)
Lockdep:
- Prevent abuse of lockdep subclasses (Waiman Long)
- Add number of dynamic keys to /proc/lockdep_stats (Waiman Long)
Plus misc cleanups and fixes"

Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/linux
Pull fscrypt update from Eric Biggers: "Add support for 'hardware-wrapped inline encryption keys' to fscrypt. When enabled on supported platforms, this feature protects file contents keys from certain attacks, such as cold boot attacks. This feature uses the block layer support for wrapped keys which was merged in 6.15. Wrapped key support has existed out-of-tree in Android for a long time, and it's finally ready for upstream now that there is a platform on which it works end-to-end with upstream. Specifically, it works on the Qualcomm SM8650 HDK, using the Qualcomm ICE (Inline Crypto Engine) and HWKM (Hardware Key Manager). The corresponding driver support is included in the SCSI tree for 6.16. Validation for this feature includes two new tests that were already merged into xfstests (generic/368 and generic/369)" * tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/linux: fscrypt: add support for hardware-wrapped keys |

Merge tag 'kvmarm-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD
KVM/arm64 updates for 6.16
* New features:
- Add large stage-2 mapping support for non-protected pKVM guests,
clawing back some performance.
- Add UBSAN support to the standalone EL2 object used in nVHE/hVHE and
protected modes.
- Enable nested virtualisation support on systems that support it
(yes, it has been a long time coming), though it is disabled by
default.
* Improvements, fixes and cleanups:
- Large rework of the way KVM tracks architecture features and links
them with the effects of control bits. This ensures correctness of
emulation (the data is automatically extracted from the published
JSON files), and helps dealing with the evolution of the
architecture.
- Significant changes to the way pKVM tracks ownership of pages,
avoiding page table walks by storing the state in the hypervisor's
vmemmap. This in turn enables the THP support described above.
- New selftest checking the pKVM ownership transition rules
- Fixes for FEAT_MTE_ASYNC being accidentally advertised to guests
even if the host didn't have it.
- Fixes for the address translation emulation, which happened to be
rather buggy in some specific contexts.
- Fixes for the PMU emulation in NV contexts, decoupling PMCR_EL0.N
from the number of counters exposed to a guest and addressing a
number of issues in the process.
- Add a new selftest for the SVE host state being corrupted by a
guest.
- Keep HCR_EL2.xMO set at all times for systems running with the
kernel at EL2, ensuring that the window for interrupts is slightly
bigger, and avoiding a pretty bad erratum on the AmpereOne HW.
- Add workaround for AmpereOne's erratum AC04_CPU_23, which suffers
from a pretty bad case of TLB corruption unless accesses to HCR_EL2
are heavily synchronised.
- Add a per-VM, per-ITS debugfs entry to dump the state of the ITS
tables in a human-friendly fashion.
- and the usual random cleanups.
