Lower the expected level of traffic in the pp_alloc_fail test and calculate failure counter thresholds based on the traffic rather than using a fixed constant. We only have "QEMU HW" in NIPA right now, and the test (due to debug dependencies) only works on debug kernels in the first place. We need some place for it to pass otherwise it seems to be bit rotting. So lower the traffic threshold so that it passes on QEMU and with a debug kernel...

2025-10-08selftests: netfilter: query conntrack state to check for port clash resolutionFlorian Westphal1-17/+41
Jakub reported this self test flaking occasionally (fails, but passes on re-run) on debug kernels. This is because the test checks for elapsed time to determine if both connections were established in parallel. Rework this to no longer depend on timing. Use busywait helper to check that both sockets have moved to established state and then query the conntrack engine for the two entries.

2025-10-08selftests: netfilter: nft_fib.sh: fix spurious test failuresFlorian Westphal1-5/+8
Jakub reports spurious failure of nft_fib.sh test. This is caused by a subtle bug inherited when i moved faulty ping from one test case to another. nft_fib.sh not only checks that the fib expression matched, it also records the number of matches and then validates we have the expected count. When I did this it was under the assumption that we would have 0 to n matching packets. In case of the failure, the entry has n+1 matching packets. This happens because ping_unreachable helper uses "ping -c 1 -w 1", instead of the intended "-W". -w alters the meaning of -c (count), namely, its then treated as number of wanted *replies* instead of "number of packets to send". So, in some cases, ping -c 1 -w 1 ends up sending two packets which then makes the test fail due to the higher-than-expected packet count. Fix the actual bug (s/-w/-W) and also change the error handling: 1. Show the number of expected packets in the error message 2. Always try to delete the key from the set. Else, later test that makes sure we don't have unexpected keys in there will always fail as well.

2025-10-07KVM: selftests: Test prefault memory during concurrent memslot removalYan Zhao1-17/+114
Expand the prefault memory selftest to add a regression test for a KVM bug where KVM's retry logic would result in (breakable) deadlock due to the memslot deletion waiting on prefaulting to release SRCU, and prefaulting waiting on the memslot to fully disappear (KVM uses a two-step process to delete memslots, and KVM x86 retries page faults if a to-be-deleted, a.k.a. INVALID, memslot is encountered). To exercise concurrent memslot remove, spawn a second thread to initiate memslot removal at roughly the same time as prefaulting. Test memslot removal for all testcases, i.e. don't limit concurrent removal to only the success case. There are essentially three prefault scenarios (so far) that are of interest: 1. Success 2. ENOENT due to no memslot 3. EAGAIN due to INVALID memslot For all intents and purposes, #1 and #2 are mutually exclusive, or rather, easier to test via separate testcases since writing to non-existent memory is trivial. But for #3, making it mutually exclusive with #1 _or_ #2 is actually more complex than testing memslot removal for all scenarios. The only requirement to let memslot removal coexist with other scenarios is a way to guarantee a stable result, e.g. that the "no memslot" test observes ENOENT, not EAGAIN, for the final checks. So, rather than make memslot removal mutually exclusive with the ENOENT scenario, simply restore the memslot and retry prefaulting. For the "no memslot" case, KVM_PRE_FAULT_MEMORY should be idempotent, i.e. should always fail with ENOENT regardless of how many times userspace attempts prefaulting. Pass in both the base GPA and the offset (instead of the "full" GPA) so that the worker can recreate the memslot.

2025-10-07selftests: drv-net: make linters happy with our importsJakub Kicinski2-11/+33
Linters are still not very happy with our __init__ files, which was pointed out in recent review (see Link). We have previously started importing things one by one to make linters happy with the test files (which import from __init__). But __init__ file itself still makes linters unhappy. To clean it up I believe we must completely remove the wildcard imports, and assign the imported modules to __all__. hds.py needs to be fixed because it seems to be importing the Python standard random from lib.net. We can't use ksft_pr() / ktap_result() in case importing from net.lib fails. Linters complain that those helpers themselves may not have been imported.

The alternative would be to intercept XSAVES/XRSTORS, which is not feasible for performance reasons - Fix a variety of fuzzing WARNs all caused by checking L1 intercepts when completing userspace I/O.

This feature splits the shared SEV-ES/SEV-SNP ASID space into separate ranges for SEV-ES and SEV-SNP guests, therefore a new module parameter is needed to control the number of ASIDs that can be used for VMs with CipherText Hiding vs. how many can be used to run SEV-ES guests - Add support for Secure TSC for SEV-SNP guests, which prevents the untrusted host from tampering with the guest's TSC frequency, while still allowing the the VMM to configure the guest's TSC frequency prior to launch - Validate the XCR0 provided by the guest (via the GHCB) to avoid bugs resulting from bogus XCR0 values - Save an SEV guest's policy if and only if LAUNCH_START fully succeeds to avoid leaving behind stale state (thankfully not consumed in KVM) - Explicitly reject non-positive effective lengths during SNP's LAUNCH_UPDATE instead of subtly relying on guest_memfd to deal with them - Reload the pre-VMRUN TSC_AUX on #VMEXIT for SEV-ES guests, not the host's desired TSC_AUX, to fix a bug where KVM was keeping a different vCPU's TSC_AUX in the host MSR until return to userspace KVM (Intel): - Preparation for FRED support - Don't retry in TDX's anti-zero-step mitigation if the target memslot is invalid, i.e. is being deleted or moved, to fix a deadlock scenario similar to the aforementioned prefaulting case - Misc bugfixes and minor cleanups" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (142 commits) KVM: x86: Export KVM-internal symbols for sub-modules only KVM: x86: Drop pointless exports of kvm_arch_xxx() hooks KVM: x86: Move kvm_intr_is_single_vcpu() to lapic.c KVM: Export KVM-internal symbols for sub-modules only KVM: s390/vfio-ap: Use kvm_is_gpa_in_memslot() instead of open coded equivalent KVM: VMX: Make CR4.CET a guest owned bit KVM: selftests: Verify MSRs are (not) in save/restore list when (un)supported KVM: selftests: Add coverage for KVM-defined registers in MSRs test KVM: selftests: Add KVM_{G,S}ET_ONE_REG coverage to MSRs test KVM: selftests: Extend MSRs test to validate vCPUs without supported features KVM: selftests: Add support for MSR_IA32_{S,U}_CET to MSRs test KVM: selftests: Add an MSR test to exercise guest/host and read/write KVM: x86: Define AMD's #HV, #VC, and #SX exception vectors KVM: x86: Define Control Protection Exception (#CP) vector KVM: x86: Add human friendly formatting for #XM, and #VE KVM: SVM: Enable shadow stack virtualization for SVM KVM: SEV: Synchronize MSR_IA32_XSS from the GHCB when it's valid KVM: SVM: Pass through shadow stack MSRs as appropriate KVM: SVM: Update dump_vmcb with shadow stack save area additions KVM: nSVM: Save/load CET Shadow Stack state to/from vmcb12/vmcb02 ...

Loads of different stuff in here, it was a busy development cycle in lots of different subsystems, with over 27k new lines added to the tree. Included in here are: - IIO updates including new drivers, reworking of existing apis, and other goodness in the sensor subsystems - MEI driver updates and additions - NVMEM driver updates - slimbus removal for an unused driver and some other minor updates - coresight driver updates and additions - MHI driver updates - comedi driver updates and fixes - extcon driver updates - interconnect driver additions - eeprom driver updates and fixes - minor UIO driver updates - tiny W1 driver updates But the majority of new code is in the rust bindings and additions, which includes: - misc driver rust binding updates for read/write support, we can now write "normal" misc drivers in rust fully, and the sample driver shows how this can be done. - Initial framework for USB driver rust bindings, which are disabled for now in the build, due to limited support, but coming in through this tree due to dependencies on other rust binding changes that were in here. I'll be enabling these back on in the build in the usb.git tree after -rc1 is out so that developers can continue to work on these in linux-next over the next development cycle. - Android Binder driver implemented in Rust. This is the big one, and was driving a huge majority of the rust binding work over the past years. Right now there are two binder drivers in the kernel, selected only at build time as to which one to use as binder wants to be included in the system at boot time. The binder C maintainers all agreed on this, as eventually, they want the C code to be removed from the tree, but it will take a few releases to get there while both are maintained to ensure that the rust implementation is fully stable and compliant with the existing userspace apis.

Pull kvm updates from Paolo Bonzini: "This excludes the bulk of the x86 changes, which I will send separately. They have two not complex but relatively unusual conflicts so I will wait for other dust to settle. guest_memfd: - Add support for host userspace mapping of guest_memfd-backed memory for VM types that do NOT use support KVM_MEMORY_ATTRIBUTE_PRIVATE (which isn't precisely the same thing as CoCo VMs, since x86's SEV-MEM and SEV-ES have no way to detect private vs. shared). This lays the groundwork for removal of guest memory from the kernel direct map, as well as for limited mmap() for guest_memfd-backed memory. For more information see: - commit a6ad54137af9 ("Merge branch 'guest-memfd-mmap' into HEAD") - guest_memfd in Firecracker: https://github.com/firecracker-microvm/firecracker/tree/feature/secret-hiding - direct map removal: https://lore.kernel.org/all/20250221160728.1584559-1-roypat@amazon.co.uk/ - mmap support: https://lore.kernel.org/all/20250328153133.3504118-1-tabba@google.com/ ARM: - Add support for FF-A 1.2 as the secure memory conduit for pKVM, allowing more registers to be used as part of the message payload. - Change the way pKVM allocates its VM handles, making sure that the privileged hypervisor is never tricked into using uninitialised data. - Speed up MMIO range registration by avoiding unnecessary RCU synchronisation, which results in VMs starting much quicker. - Add the dump of the instruction stream when panic-ing in the EL2 payload, just like the rest of the kernel has always done. This will hopefully help debugging non-VHE setups. - Add 52bit PA support to the stage-1 page-table walker, and make use of it to populate the fault level reported to the guest on failing to translate a stage-1 walk. - Add NV support to the GICv3-on-GICv5 emulation code, ensuring feature parity for guests, irrespective of the host platform. - Fix some really ugly architecture problems when dealing with debug in a nested VM. This has some bad performance impacts, but is at least correct. - Add enough infrastructure to be able to disable EL2 features and give effective values to the EL2 control registers. This then allows a bunch of features to be turned off, which helps cross-host migration. - Large rework of the selftest infrastructure to allow most tests to transparently run at EL2. This is the first step towards enabling NV testing. - Various fixes and improvements all over the map, including one BE fix, just in time for the removal of the feature. LoongArch: - Detect page table walk feature on new hardware - Add sign extension with kernel MMIO/IOCSR emulation - Improve in-kernel IPI emulation - Improve in-kernel PCH-PIC emulation - Move kvm_iocsr tracepoint out of generic code RISC-V: - Added SBI FWFT extension for Guest/VM with misaligned delegation and pointer masking PMLEN features - Added ONE_REG interface for SBI FWFT extension - Added Zicbop and bfloat16 extensions for Guest/VM - Enabled more common KVM selftests for RISC-V - Added SBI v3.0 PMU enhancements in KVM and perf driver s390: - Improve interrupt cpu for wakeup, in particular the heuristic to decide which vCPU to deliver a floating interrupt to. - Clear the PTE when discarding a swapped page because of CMMA; this bug was introduced in 6.16 when refactoring gmap code. x86 selftests: - Add #DE coverage in the fastops test (the only exception that's guest- triggerable in fastop-emulated instructions). - Fix PMU selftests errors encountered on Granite Rapids (GNR), Sierra Forest (SRF) and Clearwater Forest (CWF). - Minor cleanups and improvements x86 (guest side): - For the legacy PCI hole (memory between TOLUD and 4GiB) to UC when overriding guest MTRR for TDX/SNP to fix an issue where ACPI auto-mapping could map devices as WB and prevent the device drivers from mapping their devices with UC/UC-. - Make kvm_async_pf_task_wake() a local static helper and remove its export. - Use native qspinlocks when running in a VM with dedicated vCPU=>pCPU bindings even when PV_UNHALT is unsupported.
