Pull kvm updates from Paolo Bonzini: "ARM64: - Eager page splitting optimization for dirty logging, optionally allowing for a VM to avoid the cost of hugepage splitting in the stage-2 fault path. - Arm FF-A proxy for pKVM, allowing a pKVM host to safely interact with services that live in the Secure world. pKVM intervenes on FF-A calls to guarantee the host doesn't misuse memory donated to the hyp or a pKVM guest. - Support for running the split hypervisor with VHE enabled, known as 'hVHE' mode. This is extremely useful for testing the split hypervisor on VHE-only systems, and paves the way for new use cases that depend on having two TTBRs available at EL2. - Generalized framework for configurable ID registers from userspace. KVM/arm64 currently prevents arbitrary CPU feature set configuration from userspace, but the intent is to relax this limitation and allow userspace to select a feature set consistent with the CPU. - Enable the use of Branch Target Identification (FEAT_BTI) in the hypervisor. - Use a separate set of pointer authentication keys for the hypervisor when running in protected mode, as the host is untrusted at runtime. - Ensure timer IRQs are consistently released in the init failure paths. - Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps (FEAT_EVT), as it is a register commonly read from userspace. - Erratum workaround for the upcoming AmpereOne part, which has broken hardware A/D state management. RISC-V: - Redirect AMO load/store misaligned traps to KVM guest - Trap-n-emulate AIA in-kernel irqchip for KVM guest - Svnapot support for KVM Guest s390: - New uvdevice secret API - CMM selftest and fixes - fix racy access to target CPU for diag 9c x86: - Fix missing/incorrect #GP checks on ENCLS - Use standard mmu_notifier hooks for handling APIC access page - Drop now unnecessary TR/TSS load after VM-Exit on AMD - Print more descriptive information about the status of SEV and SEV-ES during module load - Add a test for splitting and reconstituting hugepages during and after dirty logging - Add support for CPU pinning in demand paging test - Add support for AMD PerfMonV2, with a variety of cleanups and minor fixes included along the way - Add a "nx_huge_pages=never" option to effectively avoid creating NX hugepage recovery threads (because nx_huge_pages=off can be toggled at runtime) - Move handling of PAT out of MTRR code and dedup SVM+VMX code - Fix output of PIC poll command emulation when there's an interrupt - Add a maintainer's handbook to document KVM x86 processes, preferred coding style, testing expectations, etc. - Misc cleanups, fixes and comments Generic: - Miscellaneous bugfixes and cleanups Selftests: - Generate dependency files so that partial rebuilds work as expected" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (153 commits) Documentation/process: Add a maintainer handbook for KVM x86 Documentation/process: Add a label for the tip tree handbook's coding style KVM: arm64: Fix misuse of KVM_ARM_VCPU_POWER_OFF bit index RISC-V: KVM: Remove unneeded semicolon RISC-V: KVM: Allow Svnapot extension for Guest/VM riscv: kvm: define vcpu_sbi_ext_pmu in header RISC-V: KVM: Expose IMSIC registers as attributes of AIA irqchip RISC-V: KVM: Add in-kernel virtualization of AIA IMSIC RISC-V: KVM: Expose APLIC registers as attributes of AIA irqchip RISC-V: KVM: Add in-kernel emulation of AIA APLIC RISC-V: KVM: Implement device interface for AIA irqchip RISC-V: KVM: Skeletal in-kernel AIA irqchip support RISC-V: KVM: Set kvm_riscv_aia_nr_hgei to zero RISC-V: KVM: Add APLIC related defines RISC-V: KVM: Add IMSIC related defines RISC-V: KVM: Implement guest external interrupt line management KVM: x86: Remove PRIx* definitions as they are solely for user space s390/uv: Update query for secret-UVCs s390/uv: replace scnprintf with sysfs_emit s390/uvdevice: Add 'Lock Secret Store' UVC ...

2023-07-03mm: validate the mm before dropping the mmap lockLinus Torvalds1-2/+1
Commit 408579cd627a ("mm: Update do_vmi_align_munmap() return semantics") made the return value and locking semantics of do_vmi_align_munmap() more straightforward, but in the process it ended up unlocking the mmap lock just a tad too early: the debug code doing the mmap layout validation still needs to run with the lock held, or things might change under it while it's trying to validate things. So just move the unlocking to after the validate_mm() call.

2023-07-03execve: always mark stack as growing down during early stack setupLinus Torvalds1-1/+3
While our user stacks can grow either down (all common architectures) or up (parisc and the ia64 register stack), the initial stack setup when we copy the argument and environment strings to the new stack at execve() time is always done by extending the stack downwards. But it turns out that in commit 8d7071af8907 ("mm: always expand the stack with the mmap write lock held"), as part of making the stack growing code more robust, 'expand_downwards()' was now made to actually check the vma flags: if (!(vma->vm_flags & VM_GROWSDOWN)) return -EFAULT; and that meant that this execve-time stack expansion started failing on parisc, because on that architecture, the stack flags do not contain the VM_GROWSDOWN bit. At the same time the new check in expand_downwards() is clearly correct, and simplified the callers, so let's not remove it. The solution is instead to just codify the fact that yes, during execve(), the stack grows down. This not only matches reality, it ends up being particularly simple: we already have special execve-time flags for the stack (VM_STACK_INCOMPLETE_SETUP) and use those flags to avoid page migration during this setup time (see vma_is_temporary_stack() and invalid_migration_vma()). So just add VM_GROWSDOWN to that set of temporary flags, and now our stack flags automatically match reality, and the parisc stack expansion works again. Note that the VM_STACK_INCOMPLETE_SETUP bits will be cleared when the stack is finalized, so we only add the extra VM_GROWSDOWN bit on CONFIG_STACK_GROWSUP architectures (ie parisc) rather than adding it in general.

When init_file() failed it would call file_free_rcu() on the file allocated by the caller of init_file(). It naively assumed that the correct cleanup operation would be called depending on whether it is a regular file or a backing file. However, that presupposes that the FMODE_BACKING flag would already be set which it won't be as that is done in the caller of init_file(). Fix that bug by moving the cleanup of the allocated file into the caller where it belongs in the first place. There's no good reason for init_file() to consume resources it didn't allocate.

Pull CXL updates from Dan Williams: "The highlights in terms of new functionality are support for the standard CXL Performance Monitor definition that appeared in CXL 3.0, support for device sanitization (wiping all data from a device), secure-erase (re-keying encryption of user data), and support for firmware update. The firmware update support is notable as it reuses the simple sysfs_upload interface to just cat(1) a blob to a sysfs file and pipe that to the device. Additionally there are a substantial number of cleanups and reorganizations to get ready for RCH error handling (RCH == Restricted CXL Host == current shipping hardware generation / pre CXL-2.0 topologies) and type-2 (accelerator / vendor specific) devices. For vendor specific devices they implement a subset of what the generic type-3 (generic memory expander) driver expects. As a result the rework decouples optional infrastructure from the core driver context. For RCH topologies, where the specification working group did not want to confuse pre-CXL-aware operating systems, many of the standard registers are hidden which makes support standard bus features like AER (PCIe Advanced Error Reporting) difficult. The rework arranges for the driver to help the PCI-AER core. Bjorn is on board with this direction but a late regression disocvery means the completion of this functionality needs to cook a bit longer, so it is code reorganizations only for now. Summary: - Add infrastructure for supporting background commands along with support for device sanitization and firmware update - Introduce a CXL performance monitoring unit driver based on the common definition in the specification. - Land some preparatory cleanup and refactoring for the anticipated arrival of CXL type-2 (accelerator devices) and CXL RCH (CXL-v1.1 topology) error handling. - Rework CPU cache management with respect to region configuration (device hotplug or other dynamic changes to memory interleaving) - Fix region reconfiguration vs CXL decoder ordering rules" * tag 'cxl-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (51 commits) cxl: Fix one kernel-doc comment cxl/pci: Use correct flag for sanitize polling docs: perf: Minimal introduction the the CXL PMU device and driver perf: CXL Performance Monitoring Unit driver tools/testing/cxl: add firmware update emulation to CXL memdevs tools/testing/cxl: Use named effects for the Command Effect Log tools/testing/cxl: Fix command effects for inject/clear poison cxl: add a firmware update mechanism using the sysfs firmware loader cxl/test: Add Secure Erase opcode support cxl/mem: Support Secure Erase cxl/test: Add Sanitize opcode support cxl/mem: Wire up Sanitization support cxl/mbox: Add sanitization handling machinery cxl/mem: Introduce security state sysfs file cxl/mbox: Allow for IRQ_NONE case in the isr Revert "cxl/port: Enable the HDM decoder capability for switch ports" cxl/memdev: Formalize endpoint port linkage cxl/pci: Unconditionally unmask 256B Flit errors cxl/region: Manage decoder target_type at decoder-attach time cxl/hdm: Default CXL_DEVTYPE_DEVMEM decoders to CXL_DECODER_DEVMEM ...

2023-07-01pid: use struct_size_t() helperChristian Brauner2-2/+2
Before commit d67790ddf021 ("overflow: Add struct_size_t() helper") only struct_size() existed, which expects a valid pointer instance containing the flexible array. However, when we determine the default struct pid allocation size for the associated kmem cache of a pid namespace we need to take the nesting depth of the pid namespace into account without an variable instance necessarily being available. In commit b69f0aeb0689 ("pid: Replace struct pid 1-element array with flex-array") we used to handle this the old fashioned way and cast NULL to a struct pid pointer type. However, we do apparently have a dedicated struct_size_t() helper for exactly this case. So switch to that.

2023-07-01mm: Update do_vmi_align_munmap() return semanticsLiam R. Howlett3-69/+57
Since do_vmi_align_munmap() will always honor the downgrade request on the success, the callers no longer have to deal with confusing return codes. Since all callers that request downgrade actually want the lock to be dropped, change the downgrade to an unlock request. Note that the lock still needs to be held in read mode during the page table clean up to avoid races with a map request. Update do_vmi_align_munmap() to return 0 for success. Clean up the callers and comments to always expect the unlock to be honored on the success path. The error path will always leave the lock untouched. As part of the cleanup, the wrapper function do_vmi_munmap() and callers to the wrapper are also updated.

This is extremely useful for testing the split hypervisor on VHE-only systems, and paves the way for new use cases that depend on having two TTBRs available at EL2. - Generalized framework for configurable ID registers from userspace. KVM/arm64 currently prevents arbitrary CPU feature set configuration from userspace, but the intent is to relax this limitation and allow userspace to select a feature set consistent with the CPU. - Enable the use of Branch Target Identification (FEAT_BTI) in the hypervisor. - Use a separate set of pointer authentication keys for the hypervisor when running in protected mode, as the host is untrusted at runtime. - Ensure timer IRQs are consistently released in the init failure paths. - Avoid trapping CTR_EL0 on systems with Enhanced Virtualization Traps (FEAT_EVT), as it is a register commonly read from userspace. - Erratum workaround for the upcoming AmpereOne part, which has broken hardware A/D state management. As a consequence of the hVHE series reworking the arm64 software features framework, the for-next/module-alloc branch from the arm64 tree comes along for the ride.
