      KVM: Actually create debugfs in kvm_create_vm() · b74ed7a6
      Oliver Upton authored
      Doing debugfs creation after vm creation leaves things in a
      quasi-initialized state for a while. This is further complicated by the
      fact that we tear down debugfs from kvm_destroy_vm(). Align debugfs and
      stats init/destroy with the vm init/destroy pattern to avoid any
      headaches.
      
      Note the fix for a benign mistake in error handling for calls to
      kvm_arch_create_vm_debugfs() rolled in. Since all implementations of
      the function return 0 unconditionally it isn't actually a bug at
      the moment.
      
      Lastly, tear down debugfs/stats data in the kvm_create_vm_debugfs()
      error path. Previously it was safe to assume that kvm_destroy_vm() would
      take out the garbage, that is no longer the case.

      KVM: Pass the name of the VM fd to kvm_create_vm_debugfs() · 59f82aad
      Oliver Upton authored
      At the time the VM fd is used in kvm_create_vm_debugfs(), the fd has
      been allocated but not yet installed. It is only really useful as an
      identifier in strings for the VM (such as debugfs).
      
      Treat it exactly as such by passing the string name of the fd to
      kvm_create_vm_debugfs(), futureproofing against possible misuse of the
      VM fd.

      KVM: x86/mmu: Add sanity check that MMIO SPTE mask doesn't overlap gen · 8bad4606
      Sean Christopherson authored
      Add compile-time and init-time sanity checks to ensure that the MMIO SPTE
      mask doesn't overlap the MMIO SPTE generation or the MMU-present bit.
      The generation currently avoids using bit 63, but that's as much
      coincidence as it is strictly necessarly.  That will change in the future,
      as TDX support will require setting bit 63 (SUPPRESS_VE) in the mask.
      
      Explicitly carve out the bits that are allowed in the mask so that any
      future shuffling of SPTE bits doesn't silently break MMIO caching (KVM
      has broken MMIO caching more than once due to overlapping the generation
      with other things).

      KVM: x86/mmu: rename trace function name for asynchronous page fault · 1685c0f3
      Mingwei Zhang authored
      Rename the tracepoint function from trace_kvm_async_pf_doublefault() to
      trace_kvm_async_pf_repeated_fault() to make it clear, since double fault
      has nothing to do with this trace function.
      
      Asynchronous Page Fault (APF) is an artifact generated by KVM when it
      cannot find a physical page to satisfy an EPT violation. KVM uses APF to
      tell the guest OS to do something else such as scheduling other guest
      processes to make forward progress. However, when another guest process
      also touches a previously APFed page, KVM halts the vCPU instead of
      generating a repeated APF to avoid wasting cycles.
      
      Double fault (#DF) clearly has a different meaning and a different
      consequence when triggered. #DF requires two nested contributory exceptions
      instead of two page faults faulting at the same address. A prevous bug on
      APF indicates that it may trigger a double fault in the guest [1] and
      clearly this trace function has nothing to do with it. So rename this
      function should be a valid choice.
      
      No functional change intended.

      KVM: x86/xen: Stop Xen timer before changing IRQ · c0368991
      Coleman Dietsch authored
      Stop Xen timer (if it's running) prior to changing the IRQ vector and
      potentially (re)starting the timer. Changing the IRQ vector while the
      timer is still running can result in KVM injecting a garbage event, e.g.
      vm_xen_inject_timer_irqs() could see a non-zero xen.timer_pending from
      a previous timer but inject the new xen.timer_virq.

      KVM: SVM: Disable SEV-ES support if MMIO caching is disable · 0c29397a
      Sean Christopherson authored
      Disable SEV-ES if MMIO caching is disabled as SEV-ES relies on MMIO SPTEs
      generating #NPF(RSVD), which are reflected by the CPU into the guest as
      a #VC.  With SEV-ES, the untrusted host, a.k.a. KVM, doesn't have access
      to the guest instruction stream or register state and so can't directly
      emulate in response to a #NPF on an emulated MMIO GPA.  Disabling MMIO
      caching means guest accesses to emulated MMIO ranges cause #NPF(!PRESENT),
      and those flavors of #NPF cause automatic VM-Exits, not #VC.
      
      Adjust KVM's MMIO masks to account for the C-bit location prior to doing
      SEV(-ES) setup, and document that dependency between adjusting the MMIO
      SPTE mask and SEV(-ES) setup.

      Fully re-evaluate whether or not MMIO caching can be enabled when SPTE
      masks change; simply clearing enable_mmio_caching when a configuration
      isn't compatible with caching fails to handle the scenario where the
      masks are updated, e.g. by VMX for EPT or by SVM to account for the C-bit
      location, and toggle compatibility from false=>true.
      
      Snapshot the original module param so that re-evaluating MMIO caching
      preserves userspace's desire to allow caching.  Use a snapshot approach
      so that enable_mmio_caching still reflects KVM's actual behavior.

      KVM: X86: avoid uninitialized 'fault.async_page_fault' from fixed-up #PF · 2bc685e6
      Yu Zhang authored
      kvm_fixup_and_inject_pf_error() was introduced to fixup the error code(
      e.g., to add RSVD flag) and inject the #PF to the guest, when guest
      MAXPHYADDR is smaller than the host one.
      
      When it comes to nested, L0 is expected to intercept and fix up the #PF
      and then inject to L2 directly if
      - L2.MAXPHYADDR < L0.MAXPHYADDR and
      - L1 has no intention to intercept L2's #PF (e.g., L2 and L1 have the
        same MAXPHYADDR value && L1 is using EPT for L2),
      instead of constructing a #PF VM Exit to L1. Currently, with PFEC_MASK
      and PFEC_MATCH both set to 0 in vmcs02, the interception and injection
      may happen on all L2 #PFs.
      
      However, failing to initialize 'fault' in kvm_fixup_and_inject_pf_error()
      may cause the fault.async_page_fault being NOT zeroed, and later the #PF
      being treated as a nested async page fault, and then being injected to L1.
      Instead of zeroing 'fault' at the beginning of this function, we mannually
      set the value of 'fault.async_page_fault', because false is the value we
      really expect.

       "Most of the MM queue. A few things are still pending.
      
        Liam's maple tree rework didn't make it. This has resulted in a few
        other minor patch series being held over for next time.
      
        Multi-gen LRU still isn't merged as we were waiting for mapletree to
        stabilize. The current plan is to merge MGLRU into -mm soon and to
        later reintroduce mapletree, with a view to hopefully getting both
        into 6.1-rc1.
      
        Summary:
      
         - The usual batches of cleanups from Baoquan He, Muchun Song, Miaohe
           Lin, Yang Shi, Anshuman Khandual and Mike Rapoport
      
         - Some kmemleak fixes from Patrick Wang and Waiman Long
      
         - DAMON updates from SeongJae Park

         - vmalloc speedup from Uladzislau Rezki
      
         - more folio conversion work from Matthew Wilcox
      
         - enhancements for coherent device memory mapping from Alex Sierra
      
         - addition of shared pages tracking and CoW support for fsdax, from
           Shiyang Ruan
      
         - hugetlb optimizations from Mike Kravetz
      
         - Mel Gorman has contributed some pagealloc changes to improve
           latency and realtime behaviour.
      
         - mprotect soft-dirty checking has been improved by Peter Xu
      
         - Many other singleton patches all over the place"

         - do not change nor->addr_nbytes at SFDP parsing time. At the SFDP
           parsing time we should not change members of struct spi_nor, but
           instead fill members of struct spi_nor_flash_parameters which could
           later on be used by the callers.

      Pull tracing updates from Steven Rostedt:
      
       - Runtime verification infrastructure
      
         This is the biggest change here. It introduces the runtime
         verification that is necessary for running Linux on safety critical
         systems.
      
         It allows for deterministic automata models to be inserted into the
         kernel that will attach to tracepoints, where the information on
         these tracepoints will move the model from state to state.
      
         If a state is encountered that does not belong to the model, it will
         then activate a given reactor, that could just inform the user or
         even panic the kernel (for which safety critical systems will detect
         and can recover from).
      
       - Two monitor models are also added: Wakeup In Preemptive (WIP - not to
         be confused with "work in progress"), and Wakeup While Not Running
         (WWNR).
      
       - Added __vstring() helper to the TRACE_EVENT() macro to replace
         several vsnprintf() usages that were all doing it wrong.
      
       - eprobes now can have their event autogenerated when the event name is
         left off.
      
       - The rest is various cleanups and fixes.

      Pull xfs updates from Darrick Wong:
       "The biggest changes for this release are the log scalability
        improvements, lockless lookups for the buffer cache, and making the
        attr fork a permanent part of the incore inode in preparation for
        directory parent pointers.
      
        There's also a bunch of bug fixes that have accumulated since -rc5. I
        might send you a second pull request with some more bug fixes that I'm
        still working on.
      
        Once the merge window ends, I will hand maintainership back to Dave
        Chinner until the 6.1-rc1 release so that I can conduct the design
        review for the online fsck feature, and try to get it merged.
      
        Summary:
      
         - Improve scalability of the XFS log by removing spinlocks and global
           synchronization points.
      
         - Add security labels to whiteout inodes to match the other
           filesystems.
      
         - Clean up per-ag pointer passing to simplify call sites.
      
         - Reduce verifier overhead by precalculating more AG geometry.
      
         - Implement fast-path lockless lookups in the buffer cache to reduce
           spinlock hammering.
      
         - Make attr forks a permanent part of the inode structure to fix a
           UAF bug and because most files these days tend to have security
           labels and soon will have parent pointers too.
      
         - Clean up XFS_IFORK_Q usage and give it a better name.
      
         - Fix more UAF bugs in the xattr code.
      
         - SOB my tags.
      
         - Fix some typos in the timestamp range documentation.
      
         - Fix a few more memory leaks.
      
         - Code cleanups and typo fixes.
      
         - Fix an unlocked inode fork pointer access in getbmap"

           sparc-specific pci_mmap_page_range() and pci_mmap_resource_range().
      
           This removes the ability to map the entire PCI I/O space using
           /proc/bus/pci, but we believe that's already been broken since
           v2.6.28 (Arnd Bergmann)
      
         - Move common PCI definitions to asm-generic/pci.h and rework others
           to be be more specific and more encapsulated in arches that need
           them (Stafford Horne)
      
        Power management:
      
         - Convert drivers to new *_PM_OPS macros to avoid need for '#ifdef
           CONFIG_PM_SLEEP' or '__maybe_unused' (Bjorn Helgaas)
      
        Virtualization:
      
         - Add ACS quirk for Broadcom BCM5750x multifunction NICs that isolate
           the functions but don't advertise an ACS capability (Pavan Chebbi)
      
        Error handling:
      
         - Clear PCI Status register during enumeration in case firmware left
           errors logged (Kai-Heng Feng)
      
         - When we have native control of AER, enable error reporting for all
           devices that support AER. Previously only a few drivers enabled
           this (Stefan Roese)
      
         - Keep AER error reporting enabled for switches. Previously we
           enabled this during enumeration but immediately disabled it (Stefan
           Roese)
      
         - Iterate over error counters instead of error strings to avoid
           printing junk in AER sysfs counters (Mohamed Khalfella)
      
        ASPM:
      
         - Remove pcie_aspm_pm_state_change() so ASPM config changes, e.g.,
           via sysfs, are not lost across power state changes (Kai-Heng Feng)
      
        Endpoint framework:
      
         - Don't stop an EPC when unbinding an EPF from it (Shunsuke Mie)
      
        Endpoint embedded DMA controller driver:
      
         - Simplify and clean up support for the DesignWare embedded DMA
           (eDMA) controller (Frank Li, Serge Semin)
      
        Broadcom STB PCIe controller driver:
      
         - Avoid config space accesses when link is down because we can't
           recover from the CPU aborts these cause (Jim Quinlan)
      
         - Look for power regulators described under Root Ports in DT and
           enable them before scanning the secondary bus (Jim Quinlan)
      
         - Disable/enable regulators in suspend/resume (Jim Quinlan)
      
        Freescale i.MX6 PCIe controller driver:
      
         - Simplify and clean up clock and PHY management (Richard Zhu)
      
         - Disable/enable regulators in suspend/resume (Richard Zhu)

           Pin values (Jianmin Lv)

           improve consistency (Robert Marko, Christian Marangi)
      
         - Move pipe_clk handling to PHY drivers (Dmitry Baryshkov)

           we skipped it if 'num-lanes' was absent (Serge Semin)
      
         - Allocate a 32-bit DMA-able page to be MSI target instead of using a
           driver data structure that may not be addressable with 32-bit
           address (Will McVicker)
      
         - Add DWC core support for more than 32 MSI interrupts (Dmitry
