These essentially refine some interactions between TDX guests and VMMs. The first leverages a new TDX module feature to runtime disable the ability for a VM to inject #VE exceptions. Before this feature, there was only a static on/off switch and the guest had to panic if it was configured in a bad state. The second lets the guest opt in to be able to access the topology CPUID leaves. Before this, accesses to those leaves would #VE. For both of these, it would have been nicest to just change the default behavior, but some pesky "other" OSes evidently need to retain the legacy behavior. -- The following changes since commit 59b723cd2adbac2a34fc8e12c74ae26ae45bf230: Linux 6.12-rc6 (2024-11-03 14:05:52 -1000) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git tags/x86_tdx_for_6.13-rc1 for you to fetch changes up to 7ae15e2f69bad06527668b478dff7c099ad2e6ae: x86/tdx: Enable CPU topology enumeration (2024-11-07 10:27:45 -0800) ---------------------------------------------------------------- - Add new infrastructure for reading TDX metadata - Use the newly-available metadata to: - Disable potentially nasty #VE exceptions - Get more complete CPU topology information from the VMM ---------------------------------------------------------------- Kirill A.

The arm64 version is a superset of the KVM version. There are also some arm64 changes such as commit 09e6b306f3ba ("arm64: cpufeature: discover CPU support for MPAM") with acks from the maintainers. Some RISC-V changes are missing and should come next week. Thanks, Paolo ---------------------------------------------------------------- The biggest change here is eliminating the awful idea that KVM had, of essentially guessing which pfns are refcounted pages. The reason to do so was that KVM needs to map both non-refcounted pages (for example BARs of VFIO devices) and VM_PFNMAP/VM_MIXMEDMAP VMAs that contain refcounted pages. However, the result was security issues in the past, and more recently the inability to map VM_IO and VM_PFNMAP memory that _is_ backed by struct page but is not refcounted. In particular this broke virtio-gpu blob resources (which directly map host graphics buffers into the guest as "vram" for the virtio-gpu device) with the amdgpu driver, because amdgpu allocates non-compound higher order pages and the tail pages could not be mapped into KVM. This requires adjusting all uses of struct page in the per-architecture code, to always work on the pfn whenever possible. The large series that did this, from David Stevens and Sean Christopherson, also cleaned up substantially the set of functions that provided arch code with the pfn for a host virtual addresses. The previous maze of twisty little passages, all different, is replaced by five functions (__gfn_to_page, __kvm_faultin_pfn, the non-__ versions of these two, and kvm_prefetch_pages) saving almost 200 lines of code. ARM: * Support for stage-1 permission indirection (FEAT_S1PIE) and permission overlays (FEAT_S1POE), including nested virt + the emulated page table walker * Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This call was introduced in PSCIv1.3 as a mechanism to request hibernation, similar to the S4 state in ACPI * Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As part of it, introduce trivial initialization of the host's MPAM context so KVM can use the corresponding traps * PMU support under nested virtualization, honoring the guest hypervisor's trap configuration and event filtering when running a nested guest * Fixes to vgic ITS serialization where stale device/interrupt table entries are not zeroed when the mapping is invalidated by the VM * Avoid emulated MMIO completion if userspace has requested synchronous external abort injection * Various fixes and cleanups affecting pKVM, vCPU initialization, and selftests LoongArch: * Add iocsr and mmio bus simulation in kernel. * Add in-kernel interrupt controller emulation. * Add support for virtualization extensions to the eiointc irqchip. PPC: * Drop lingering and utterly obsolete references to PPC970 KVM, which was removed 10 years ago. * Fix incorrect documentation references to non-existing ioctls RISC-V: * Accelerate KVM RISC-V when running as a guest * Perf support to collect KVM guest statistics from host side s390: * New selftests: more ucontrol selftests and CPU model sanity checks * Support for the gen17 CPU model * List registers supported by KVM_GET/SET_ONE_REG in the documentation x86: * Cleanup KVM's handling of Accessed and Dirty bits to dedup code, improve documentation, harden against unexpected changes. Even if the hardware A/D tracking is disabled, it is possible to use the hardware-defined A/D bits to track if a PFN is Accessed and/or Dirty, and that removes a lot of special cases. * Elide TLB flushes when aging secondary PTEs, as has been done in x86's primary MMU for over 10 years. * Recover huge pages in-place in the TDP MMU when dirty page logging is toggled off, instead of zapping them and waiting until the page is re-accessed to create a huge mapping. This reduces vCPU jitter. * Batch TLB flushes when dirty page logging is toggled off. This reduces the time it takes to disable dirty logging by ~3x. * Remove the shrinker that was (poorly) attempting to reclaim shadow page tables in low-memory situations. * Clean up and optimize KVM's handling of writes to MSR_IA32_APICBASE. * Advertise CPUIDs for new instructions in Clearwater Forest * Quirk KVM's misguided behavior of initialized certain feature MSRs to their maximum supported feature set, which can result in KVM creating invalid vCPU state. E.g. initializing PERF_CAPABILITIES to a non-zero value results in the vCPU having invalid state if userspace hides PDCM from the guest, which in turn can lead to save/restore failures. * Fix KVM's handling of non-canonical checks for vCPUs that support LA57 to better follow the "architecture", in quotes because the actual behavior is poorly documented. E.g. most MSR writes and descriptor table loads ignore CR4.LA57 and operate purely on whether the CPU supports LA57. * Bypass the register cache when querying CPL from kvm_sched_out(), as filling the cache from IRQ context is generally unsafe; harden the cache accessors to try to prevent similar issues from occuring in the future. The issue that triggered this change was already fixed in 6.12, but was still kinda latent. * Advertise AMD_IBPB_RET to userspace, and fix a related bug where KVM over-advertises SPEC_CTRL when trying to support cross-vendor VMs. * Minor cleanups * Switch hugepage recovery thread to use vhost_task. These kthreads can consume significant amounts of CPU time on behalf of a VM or in response to how the VM behaves (for example how it accesses its memory); therefore KVM tried to place the thread in the VM's cgroups and charge the CPU time consumed by that work to the VM's container. However the kthreads did not process SIGSTOP/SIGCONT, and therefore cgroups which had KVM instances inside could not complete freezing. Fix this by replacing the kthread with a PF_USER_WORKER thread, via the vhost_task abstraction. Another 100+ lines removed, with generally better behavior too like having these threads properly parented in the process tree. * Revert a workaround for an old CPU erratum (Nehalem/Westmere) that didn't really work; there was really nothing to work around anyway: the broken patch was meant to fix nested virtualization, but the PERF_GLOBAL_CTRL MSR is virtualized and therefore unaffected by the erratum. * Fix 6.12 regression where CONFIG_KVM will be built as a module even if asked to be builtin, as long as neither KVM_INTEL nor KVM_AMD is 'y'. x86 selftests: * x86 selftests can now use AVX. Documentation: * Use rST internal links * Reorganize the introduction to the API document Generic: * Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock instead of RCU, so that running a vCPU on a different task doesn't encounter long due to having to wait for all CPUs become quiescent. In general both reads and writes are rare, but userspace that supports confidential computing is introducing the use of "helper" vCPUs that may jump from one host processor to another. Those will be very happy to trigger a synchronize_rcu(), and the effect on performance is quite the disaster. ---------------------------------------------------------------- Anup Patel (13): RISC-V:

There are still additional series needed to solve problems with IRQs, but this is the iommufd side of the work. For those following, these series are still progressing: - Draft AMD IOMMU nested translation: https://lore.kernel.org/linux-iommu/20240112000646.98001-1-suravee.suthikulpanit@amd.com (and many other AMD patches to prepare for this) - Draft vBTM support for SMMUv3: https://lore.kernel.org/linux-iommu/20240208151837.35068-1-shameerali.kolothum.thodi@huawei.com/ - Draft RISCV nesting support: https://lore.kernel.org/all/20240507142600.23844-1-zong.li@sifive.com/ - Grace command queue passthrough iommufd support: https://lore.kernel.org/all/cover.1712978212.git.nicolinc@nvidia.com/ Patches for PASID support in iommufd & vfio: https://lore.kernel.org/r/20241104132513.15890-1-yi.l.liu@intel.com https://lore.kernel.org/r/20241108121742.18889-1-yi.l.liu@intel.com (Several precursor series were merged this cycle so I hope this to go next cycle) A lot of the iommufd support has now been merged to qemu, with more progressing. This has a shared branch Will created for some of the SMMUv3 code. I have two patches renaming a function that I would like to get merged in this window as well to simplify next cycle. They need both iommufd and iommu trees to be merged together so I think there will be another tiny pull request. Thanks, Jason The following changes since commit 8e929cb546ee42c9a61d24fae60605e9e3192354: Linux 6.12-rc3 (2024-10-13 14:33:32 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd.git tags/for-linus-iommufd for you to fetch changes up to 6d026e6d48cd2a95407c8fdd8d6187b871401c23: iommu/arm-smmu-v3: Import IOMMUFD module namespace (2024-11-14 21:07:15 -0400) ---------------------------------------------------------------- iommufd 6.13 merge window pull Several new features and uAPI for iommufd: - IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the backing memory for an iommu mapping. To date VFIO/iommufd have used VMA's and pin_user_pages(), this now allows using memfds and memfd_pin_folios(). Notably this creates a pure folio path from the memfd to the iommu page table where memory is never broken down to PAGE_SIZE. - IOMMU_IOAS_CHANGE_PROCESS moves the pinned page accounting between two processes. Combined with the above this allows iommufd to support a VMM re-start using exec() where something like qemu would exec() a new version of itself and fd pass the memfds/iommufd/etc to the new process. The memfd allows DMA access to the memory to continue while the new process is getting setup, and the CHANGE_PROCESS updates all the accounting. - Support for fault reporting to userspace on non-PRI HW, such as ARM stall-mode embedded devices. - IOMMU_VIOMMU_ALLOC introduces the concept of a HW/driver backed virtual iommu. This will be used by VMMs to access hardware features that are contained with in a VM. The first use is to inform the kernel of the virtual SID to physical SID mapping when issuing SID based invalidation on ARM. Further uses will tie HW features that are directly accessed by the VM, such as invalidation queue assignment and others. - IOMMU_VDEVICE_ALLOC informs the kernel about the mapping of virtual device to physical device within a VIOMMU. Minimially this is used to translate VM issued cache invalidation commands from virtual to physical device IDs. - Enhancements to IOMMU_HWPT_INVALIDATE and IOMMU_HWPT_ALLOC to work with the VIOMMU - ARM SMMuv3 support for nested translation. Using the VIOMMU and VDEVICE the driver can model this HW's behavior for nested translation.

Subject: [GIT PULL] ring-buffer: Updates for 6.13 From: Steven Rostedt To: Linus Torvalds Cc: LKML , Masami Hiramatsu , Mathieu Desnoyers , Julia Lawall , Petr Pavlu , Thorsten Blum , liujing Date: Wed, 20 Nov 2024 15:48:33 -0500 Linus, trace ring-buffer updates for v6.13 - Limit the time interrupts are disabled in rb_check_pages() The rb_check_pages() is called after the ring buffer size is updated to make sure that the ring buffer has not been corrupted. Commit c2274b908db05 ("ring-buffer: Fix a race between readers and resize checks") fixed a race with the check pages and simultaneous resizes to the ring buffer by adding a raw_spin_lock_irqsave() around the check operation. Although this was a simple fix, it would hold interrupts disabled for non determinative amount of time. This could harm PREEMPT_RT operations. Instead, modify the logic by adding a counter when the buffer is modified and to release the raw_spin_lock() at each iteration. It checks the counter under the lock to see if a modification happened during the loop, and if it did, it would restart the loop up to 3 times. After 3 times, it will simply exit the check, as it is unlikely that would ever happen as buffer resizes are rare occurrences. - Replace some open coded str_low_high() with the helper - Fix some documentation/comments Please pull the latest trace-ring-buffer-v6.13 tree, which can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace.git trace-ring-buffer-v6.13 Tag SHA1: 787da17c39b4daa2c77c98a0a2821f68a030022a Head SHA1: 537affea1672a841cd5b87b208c193a3a542c7cf Julia Lawall (1): ring-buffer: Reorganize kerneldoc parameter names Petr Pavlu (1): ring-buffer: Limit time with disabled interrupts in rb_check_pages() Thorsten Blum (1): ring-buffer: Use str_low_high() helper in ring_buffer_producer() liujing (1): ring-buffer: Correct a grammatical error in a comment ---- kernel/trace/ring_buffer.c | 102 +++++++++++++++++++++++++---------- kernel/trace/ring_buffer_benchmark.c | 4 +- 2 files changed, 76 insertions(+), 30 deletions(-) --------------------------- diff --git a/kernel/trace/ring_buffer.c b/kernel/trace/ring_buffer.c index 3ea4f7bb1837..d6100a7da483 100644 --- a/kernel/trace/ring_buffer.c +++ b/kernel/trace/ring_buffer.c @@ -482,6 +482,8 @@ struct ring_buffer_per_cpu { unsigned long nr_pages; unsigned int current_context; struct list_head *pages; + /* pages generation counter, incremented when the list changes */ + unsigned long cnt; struct buffer_page *head_page; /* read from head */ struct buffer_page *tail_page; /* write to tail */ struct buffer_page *commit_page; /* committed pages */ @@ -1475,40 +1477,87 @@ static void rb_check_bpage(struct ring_buffer_per_cpu *cpu_buffer, RB_WARN_ON(cpu_buffer, val & RB_FLAG_MASK); } +static bool rb_check_links(struct ring_buffer_per_cpu *cpu_buffer, + struct list_head *list) +{ + if (RB_WARN_ON(cpu_buffer, + rb_list_head(rb_list_head(list->next)->prev) != list)) + return false; + + if (RB_WARN_ON(cpu_buffer, + rb_list_head(rb_list_head(list->prev)->next) != list)) + return false; + + return true; +} + /** * rb_check_pages - integrity check of buffer pages * @cpu_buffer: CPU buffer with pages to test * * As a safety measure we check to make sure the data pages have not * been corrupted. - * - * Callers of this function need to guarantee that the list of pages doesn't get - * modified during the check.
