git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire updates from Takashi Sakamoto: "This consist of three parts; UAPI update, OHCI driver update, and several bug fixes. Firstly, the 1394 OHCI specification defines method to retrieve hardware time stamps for asynchronous communication, which was previously unavailable in user space. This adds new events to the UAPI, allowing applications to retrieve the time when asynchronous packet are received and sent. The new events are tested in the bleeding edge of libhinawa and look to work well. The new version of libhinawa will be released after current merge window is closed: https://git.kernel.org/pub/scm/libs/ieee1394/libhinawa.git/ Secondly, the FireWire stack includes a PCM device driver for 1394 OHCI hardware, This change modernizes the driver by managed resource (devres) framework.

2023-07-04rdma: fix INFINIBAND_USER_ACCESS dependencyArnd Bergmann1-2/+4
After a change to the bnxt_re driver, it fails to link when CONFIG_INFINIBAND_USER_ACCESS is disabled: aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o: in function `bnxt_re_handler_BNXT_RE_METHOD_ALLOC_PAGE': ib_verbs.c:(.text+0xd64): undefined reference to `ib_uverbs_get_ucontext_file' aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x168): undefined reference to `uverbs_idr_class' aarch64-linux-ld: drivers/infiniband/hw/bnxt_re/ib_verbs.o:(.rodata+0x1a8): undefined reference to `uverbs_destroy_def_handler' The problem is that the 'bnxt_re_uapi_defs' structure is built unconditionally and references a couple of functions that are never really called in this configuration but instead require other functions that are left out. Adding an #ifdef around the new code, or a Kconfig dependency would address this problem, but adding the compile-time check inside of the UAPI_DEF_CHAIN_OBJ_TREE_NAMED() macro seems best because that also addresses the problem in other drivers that may run into the same dependency.

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 ...

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.

2023-07-03vhost: Allow worker switching while work is queueingMike Christie1-3/+1
This patch drops the requirement that we can only switch workers if work has not been queued by using RCU for the vq based queueing paths and a mutex for the device wide flush. We can also use this to support SIGKILL properly in the future where we should exit almost immediately after getting that signal. With this patch, when get_signal returns true, we can set the vq->worker to NULL and do a synchronize_rcu to prevent new work from being queued to the vhost_task that has been killed.

2023-07-03vhost: allow userspace to create workersMike Christie2-0/+49
For vhost-scsi with 3 vqs or more and a workload that tries to use them in parallel like: fio --filename=/dev/sdb --direct=1 --rw=randrw --bs=4k \ --ioengine=libaio --iodepth=128 --numjobs=3 the single vhost worker thread will become a bottlneck and we are stuck at around 500K IOPs no matter how many jobs, virtqueues, and CPUs are used. To better utilize virtqueues and available CPUs, this patch allows userspace to create workers and bind them to vqs. You can have N workers per dev and also share N workers with M vqs on that dev. This patch adds the interface related code and the next patch will hook vhost-scsi into it. The patches do not try to hook net and vsock into the interface because: 1. multiple workers don't seem to help vsock. The problem is that with only 2 virtqueues we never fully use the existing worker when doing bidirectional tests. This seems to match vhost-scsi where we don't see the worker as a bottleneck until 3 virtqueues are used. 2. net already has a way to use multiple workers.

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 ...

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.

2023-07-01xtensa: fix NOMMU build with lock_mm_and_find_vma() conversionLinus Torvalds1-2/+3
It turns out that xtensa has a really odd configuration situation: you can do a no-MMU config, but still have the page fault code enabled. Which doesn't sound all that sensible, but it turns out that xtensa can have protection faults even without the MMU, and we have this: config PFAULT bool "Handle protection faults" if EXPERT && !MMU default y help Handle protection faults. MMU configurations must enable it. noMMU configurations may disable it if used memory map never generates protection faults or faults are always fatal. If unsure, say Y. which completely violated my expectations of the page fault handling.

2023-06-30pid: Replace struct pid 1-element array with flex-arrayKees Cook1-1/+1
For pid namespaces, struct pid uses a dynamically sized array member, "numbers". This was implemented using the ancient 1-element fake flexible array, which has been deprecated for decades. Replace it with a C99 flexible array, refactor the array size calculations to use struct_size(), and address elements via indexes. Note that the static initializer (which defines a single element) works as-is, and requires no special handling. Without this, CONFIG_UBSAN_BOUNDS (and potentially CONFIG_FORTIFY_SOURCE) will trigger bounds checks: https://lore.kernel.org/lkml/20230517-bushaltestelle-super-e223978c1ba6@brauner Cc: Christian Brauner <brauner@kernel.org> Cc: Jan Kara <jack@suse.cz> Cc: Jeff Xu <jeffxu@google.com> Cc: Andreas Gruenbacher <agruenba@redhat.com> Cc: Daniel Verkamp <dverkamp@chromium.org> Cc: "Paul E.

Fix the STI console to be able to execute either the 64-bit STI ROM code or the 32-bit STI ROM code. This is necessary on 64-bit only machines (e.g. C8000 workstation) which otherwise won't show the STI text console with HP graphic cards like Visualize-FX5/FX10/FXe. Note that when calling 32-bit code from a 64-bit kernel one needs to copy contents on the CPU stack from high memory down below the 4GB limit.
