2025-02-12fs: add open_tree_attr()Christian Brauner1-1/+3
Add open_tree_attr() which allow to atomically create a detached mount tree and set mount options on it. If OPEN_TREE_CLONE is used this will allow the creation of a detached mount with a new set of mount options without it ever being exposed to userspace without that set of mount options applied.

2025-02-12statmount: add a new supported_mask fieldJeff Layton1-1/+3
Some of the fields in the statmount() reply can be optional. If the kernel has nothing to emit in that field, then it doesn't set the flag in the reply. This presents a problem: There is currently no way to know what mask flags the kernel supports since you can't always count on them being in the reply. Add a new STATMOUNT_SUPPORTED_MASK flag and field that the kernel can set in the reply. Userland can use this to determine if the fields it requires from the kernel are supported. This also gives us a way to deprecate fields in the future, if that should become necessary.

2025-02-12statmount: allow to retrieve idmappingsChristian Brauner1-1/+7
This adds the STATMOUNT_MNT_UIDMAP and STATMOUNT_MNT_GIDMAP options. It allows the retrieval of idmappings via statmount(). Currently it isn't possible to figure out what idmappings are applied to an idmapped mount. This information is often crucial. Before statmount() the only realistic options for an interface like this would have been to add it to /proc/<pid>/fdinfo/<nr> or to expose it in /proc/<pid>/mountinfo. Both solution would have been pretty ugly and would've shown information that is of strong interest to some application but not all. statmount() is perfect for this. The idmappings applied to an idmapped mount are shown relative to the caller's user namespace. This is the most useful solution that doesn't risk leaking information or confuse the caller. For example, an idmapped mount might have been created with the following idmappings: mount --bind -o X-mount.idmap="0:10000:1000 2000:2000:1 3000:3000:1" /srv /opt Listing the idmappings through statmount() in the same context shows: mnt_id: 2147485088 mnt_parent_id: 2147484816 fs_type: btrfs mnt_root: /srv mnt_point: /opt mnt_opts: ssd,discard=async,space_cache=v2,subvolid=5,subvol=/ mnt_uidmap[0]: 0 10000 1000 mnt_uidmap[1]: 2000 2000 1 mnt_uidmap[2]: 3000 3000 1 mnt_gidmap[0]: 0 10000 1000 mnt_gidmap[1]: 2000 2000 1 mnt_gidmap[2]: 3000 3000 1 But the idmappings might not always be resolvable in the caller's user namespace. For example: unshare --user --map-root In this case statmount() will skip any mappings that fil to resolve in the caller's idmapping: mnt_id: 2147485087 mnt_parent_id: 2147484016 fs_type: btrfs mnt_root: /srv mnt_point: /opt mnt_opts: ssd,discard=async,space_cache=v2,subvolid=5,subvol=/ The caller can differentiate between a mount not being idmapped and a mount that is idmapped but where all mappings fail to resolve in the caller's idmapping by check for the STATMOUNT_MNT_{G,U}IDMAP flag being raised but the number of mappings in ->mnt_{g,u}idmap_num being zero. Note that statmount() requires that the whole range must be resolvable in the caller's user namespace. If a subrange fails to map it will still list the map as not resolvable. This is a practical compromise to avoid having to find which subranges are resovable and wich aren't. Idmappings are listed as a string array with each mapping separated by zero bytes. This allows to retrieve the idmappings and immediately use them for writing to e.g., /proc/<pid>/{g,u}id_map and it also allow for simple iteration like: if (stmnt->mask & STATMOUNT_MNT_UIDMAP) { const char *idmap = stmnt->str + stmnt->mnt_uidmap; for (size_t idx = 0; idx < stmnt->mnt_uidmap_nr; idx++) { printf("mnt_uidmap[%lu]: %s\n", idx, idmap); idmap += strlen(idmap) + 1; } } Link: https://lore.kernel.org/r/20250204-work-mnt_idmap-statmount-v2-2-007720f39f2e@kernel.org Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Christian Brauner <brauner@kernel.org>

2025-02-11thermal/netlink: Prevent userspace segmentation fault by adjusting UAPI headerZhang Rui1-1/+1
The intel-lpmd tool [1], which uses the THERMAL_GENL_ATTR_CPU_CAPABILITY attribute to receive HFI events from kernel space, encounters a segmentation fault after commit 1773572863c4 ("thermal: netlink: Add the commands and the events for the thresholds"). The issue arises because the THERMAL_GENL_ATTR_CPU_CAPABILITY raw value was changed while intel_lpmd still uses the old value. Although intel_lpmd can be updated to check the THERMAL_GENL_VERSION and use the appropriate THERMAL_GENL_ATTR_CPU_CAPABILITY value, the commit itself is questionable. The commit introduced a new element in the middle of enum thermal_genl_attr, which affects many existing attributes and introduces potential risks and unnecessary maintenance burdens for userspace thermal netlink event users. Solve the issue by moving the newly introduced THERMAL_GENL_ATTR_TZ_PREV_TEMP attribute to the end of the enum thermal_genl_attr. This ensures that all existing thermal generic netlink attributes remain unaffected.

2025-02-10blk-crypto: add ioctls to create and prepare hardware-wrapped keysEric Biggers2-4/+46
Until this point, the kernel can use hardware-wrapped keys to do encryption if userspace provides one -- specifically a key in ephemerally-wrapped form. However, no generic way has been provided for userspace to get such a key in the first place. Getting such a key is a two-step process. First, the key needs to be imported from a raw key or generated by the hardware, producing a key in long-term wrapped form. This happens once in the whole lifetime of the key. Second, the long-term wrapped key needs to be converted into ephemerally-wrapped form. This happens each time the key is "unlocked". In Android, these operations are supported in a generic way through KeyMint, a userspace abstraction layer. However, that method is Android-specific and can't be used on other Linux systems, may rely on proprietary libraries, and also misleads people into supporting KeyMint features like rollback resistance that make sense for other KeyMint keys but don't make sense for hardware-wrapped inline encryption keys. Therefore, this patch provides a generic kernel interface for these operations by introducing new block device ioctls: - BLKCRYPTOIMPORTKEY: convert a raw key to long-term wrapped form. - BLKCRYPTOGENERATEKEY: have the hardware generate a new key, then return it in long-term wrapped form. - BLKCRYPTOPREPAREKEY: convert a key from long-term wrapped form to ephemerally-wrapped form. These ioctls are implemented using new operations in blk_crypto_ll_ops.

2025-02-06Merge branch 'io_uring-zero-copy-rx'Jakub Kicinski1-0/+7
David Wei says: ==================== io_uring zero copy rx This patchset contains net/ patches needed by a new io_uring request implementing zero copy rx into userspace pages, eliminating a kernel to user copy. We configure a page pool that a driver uses to fill a hw rx queue to hand out user pages instead of kernel pages. Any data that ends up hitting this hw rx queue will thus be dma'd into userspace memory directly, without needing to be bounced through kernel memory. 'Reading' data out of a socket instead becomes a _notification_ mechanism, where the kernel tells userspace where the data is. The overall approach is similar to the devmem TCP proposal. This relies on hw header/data split, flow steering and RSS to ensure packet headers remain in kernel memory and only desired flows hit a hw rx queue configured for zero copy. Configuring this is outside of the scope of this patchset. We share netdev core infra with devmem TCP. The main difference is that io_uring is used for the uAPI and the lifetime of all objects are bound to an io_uring instance. Data is 'read' using a new io_uring request type. When done, data is returned via a new shared refill queue. A zero copy page pool refills a hw rx queue from this refill queue directly. Of course, the lifetime of these data buffers are managed by io_uring rather than the networking stack, with different refcounting rules. This patchset is the first step adding basic zero copy support. We will extend this iteratively with new features e.g. dynamically allocated zero copy areas, THP support, dmabuf support, improved copy fallback, general optimisations and more. In terms of netdev support, we're first targeting Broadcom bnxt. Patches aren't included since Taehee Yoo has already sent a more comprehensive patchset adding support in [1]. Google gve should already support this, and Mellanox mlx5 support is WIP pending driver changes. =========== Performance =========== Note: Comparison with epoll + TCP_ZEROCOPY_RECEIVE isn't done yet.

2025-02-05pidfd: add PIDFD_SELF* sentinels to refer to own thread/processLorenzo Stoakes1-0/+24
It is useful to be able to utilise the pidfd mechanism to reference the current thread or process (from a userland point of view - thread group leader from the kernel's point of view). Therefore introduce PIDFD_SELF_THREAD to refer to the current thread, and PIDFD_SELF_THREAD_GROUP to refer to the current thread group leader. For convenience and to avoid confusion from userland's perspective we alias these: * PIDFD_SELF is an alias for PIDFD_SELF_THREAD - This is nearly always what the user will want to use, as they would find it surprising if for instance fd's were unshared()'d and they wanted to invoke pidfd_getfd() and that failed. * PIDFD_SELF_PROCESS is an alias for PIDFD_SELF_THREAD_GROUP - Most users have no concept of thread groups or what a thread group leader is, and from userland's perspective and nomenclature this is what userland considers to be a process. We adjust pidfd_get_task() and the pidfd_send_signal() system call with specific handling for this, implementing this functionality for process_madvise(), process_mrelease() (albeit, using it here wouldn't really make sense) and pidfd_send_signal().

2025-02-03drm/xe/pxp/uapi: Add API to mark a BO as using PXPDaniele Ceraolo Spurio1-0/+19
The driver needs to know if a BO is encrypted with PXP to enable the display decryption at flip time. Furthermore, we want to keep track of the status of the encryption and reject any operation that involves a BO that is encrypted using an old key. There are two points in time where such checks can kick in: 1 - at VM bind time, all operations except for unmapping will be rejected if the key used to encrypt the BO is no longer valid. This check is opt-in via a new VM_BIND flag, to avoid a scenario where a malicious app purposely shares an invalid BO with a non-PXP aware app (such as a compositor). If the VM_BIND was failed, the compositor would be unable to display anything at all. Allowing the bind to go through means that output still works, it just displays garbage data within the bounds of the illegal BO. 2 - at job submission time, if the queue is marked as using PXP, all objects bound to the VM will be checked and the submission will be rejected if any of them was encrypted with a key that is no longer valid. Note that there is no risk of leaking the encrypted data if a user does not opt-in to those checks; the only consequence is that the user will not realize that the encryption key is changed and that the data is no longer valid. v2: Better commnnts and descriptions (John), rebase v3: Properly return the result of key_assign up the stack, do not use xe_bo in display headers (Jani) v4: improve key_instance variable documentation (John) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Matthew Brost <matthew.brost@intel.com> Cc: Thomas Hellström <thomas.hellstrom@linux.intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Cc: Jani Nikula <jani.nikula@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250129174140.948829-11-daniele.ceraolospurio@intel.com

Vulkan can't support DCC and Z/S compression on GFX12 without WRITE_COMPRESS_DISABLE in this commit or a completely different DCC interface. AMDGPU_TILING_GFX12_SCANOUT is added because it's already used by userspace.

Pull nfsd updates from Chuck Lever: "Jeff Layton contributed an implementation of NFSv4.2+ attribute delegation, as described here: https://www.ietf.org/archive/id/draft-ietf-nfsv4-delstid-08.html This interoperates with similar functionality introduced into the Linux NFS client in v6.11. An attribute delegation permits an NFS client to manage a file's mtime, rather than flushing dirty data to the NFS server so that the file's mtime reflects the last write, which is considerably slower. Neil Brown contributed dynamic NFSv4.1 session slot table resizing. This facility enables NFSD to increase or decrease the number of slots per NFS session depending on server memory availability. More session slots means greater parallelism. Chuck Lever fixed a long-standing latent bug where NFSv4 COMPOUND encoding screws up when crossing a page boundary in the encoding buffer. This is a zero-day bug, but hitting it is rare and depends on the NFS client implementation. The Linux NFS client does not happen to trigger this issue. A variety of bug fixes and other incremental improvements fill out the list of commits in this release.

Add host bridge .enable_device() and .disable_device() hooks for bridges that need to configure things like Requester ID to StreamID mapping when enabling devices (Frank Li) - Extend struct pci_ecam_ops with .enable_device() and .disable_device() hooks so drivers that use pci_host_common_probe() instead of their own .probe() have a way to set the .enable_device() callbacks (Marc Zyngier) - Drop 'No bus range found' message so we don't complain when DTs don't specify the default 'bus-range = <0x00 0xff>' (Bjorn Helgaas) - Rename the drivers/pci/of_property.c struct of_pci_range to of_pci_range_entry to avoid confusion with the global of_pci_range in include/linux/of_address.h (Bjorn Helgaas) Driver binding: - Update resource request API documentation to encourage callers to supply a driver name when requesting resources (Philipp Stanner) - Export pci_intx_unmanaged() and pcim_intx() (always managed) so callers of pci_intx() (which is sometimes managed) can explicitly choose the one they need (Philipp Stanner) - Convert drivers from pci_intx() to always-managed pcim_intx() or never-managed pci_intx_unmanaged(): amd_sfh, ata (ahci, ata_piix, pata_rdc, sata_sil24, sata_sis, sata_uli, sata_vsc), bnx2x, bna, ntb, qtnfmac, rtsx, tifm_7xx1, vfio, xen-pciback (Philipp Stanner) - Remove pci_intx_unmanaged() since pci_intx() is now always unmanaged and pcim_intx() is always managed (Philipp Stanner) Error handling: - Unexport pcie_read_tlp_log() to encourage drivers to use PCI core logging rather than building their own (Ilpo Järvinen) - Move TLP Log handling to its own file (Ilpo Järvinen) - Store number of supported End-End TLP Prefixes always so we can read the correct number of DWORDs from the TLP Prefix Log (Ilpo Järvinen) - Read TLP Prefixes in addition to the Header Log in pcie_read_tlp_log() (Ilpo Järvinen) - Add pcie_print_tlp_log() to consolidate printing of TLP Header and Prefix Log (Ilpo Järvinen) - Quirk the Intel Raptor Lake-P PIO log size to accommodate vendor BIOSes that don't configure it correctly (Takashi Iwai) ASPM: - Save parent L1 PM Substates config so when we restore it along with an endpoint's config, the parent info isn't junk (Jian-Hong Pan) Power management: - Avoid D3 for Root Ports on TUXEDO Sirius Gen1 with old BIOS because the system can't wake up from suspend (Werner Sembach) Endpoint framework: - Destroy the EPC device in devm_pci_epc_destroy(), which previously didn't call devres_release() (Zijun Hu) - Finish virtual EP removal in pci_epf_remove_vepf(), which previously caused a subsequent pci_epf_add_vepf() to fail with -EBUSY (Zijun Hu) - Write BAR_MASK before iATU registers in pci_epc_set_bar() so we don't depend on the BAR_MASK reset value being larger than the requested BAR size (Niklas Cassel) - Prevent changing BAR size/flags in pci_epc_set_bar() to prevent reads from bypassing the iATU if we reduced the BAR size (Niklas Cassel) - Verify address alignment when programming iATU so we don't attempt to write bits that are read-only because of the BAR size, which could lead to directing accesses to the wrong address (Niklas Cassel) - Implement artpec6 pci_epc_features so we can rely on all drivers supporting it so we can use it in EPC core code (Niklas Cassel) - Check for BARs of fixed size to prevent endpoint drivers from trying to change their size (Niklas Cassel) - Verify that requested BAR size is a power of two when endpoint driver sets the BAR (Niklas Cassel) Endpoint framework tests: - Clear pci-epf-test dma_chan_rx, not dma_chan_tx, after freeing dma_chan_rx (Mohamed Khalfella) - Correct the DMA MEMCPY test so it doesn't fail if the Endpoint supports both DMA_PRIVATE and DMA_MEMCPY (Manivannan Sadhasivam) - Add pci-epf-test and pci_endpoint_test support for capabilities (Niklas Cassel) - Add Endpoint test for consecutive BARs (Niklas Cassel) - Remove redundant comparison from Endpoint BAR test because a > 1MB BAR can always be exactly covered by iterating with a 1MB buffer (Hans Zhang) -

Add DT compatible string 'fsl,imx8q-pcie-ep' and driver support for i.MX8Q series (i.MX8QM, i.MX8QXP, and i.MX8DXL) Endpoints (Frank Li) - Add DT binding for optional i.MX95 Refclk and driver support to enable it if the platform hasn't enabled it (Richard Zhu) - Configure PHY based on controller being in Root Complex or Endpoint mode (Frank Li) - Rely on dbi2 and iATU base addresses from DT via dw_pcie_get_resources() instead of hardcoding them (Richard Zhu) - Deassert apps_reset in imx_pcie_deassert_core_reset() since it is asserted in imx_pcie_assert_core_reset() (Richard Zhu) - Add missing reference clock enable or disable logic for IMX6SX, IMX7D, IMX8MM (Richard Zhu) - Remove redundant imx7d_pcie_init_phy() since imx7d_pcie_enable_ref_clk() does the same thing (Richard Zhu) Freescale Layerscape PCIe controller driver: - Simplify by using syscon_regmap_lookup_by_phandle_args() instead of syscon_regmap_lookup_by_phandle() followed by of_property_read_u32_array() (Krzysztof Kozlowski) Marvell MVEBU PCIe controller driver: -

Move Airoha EN7581 post-reset delay from the en7581 clock .enable() method to mtk_pcie_en7581_power_up() (Lorenzo Bianconi) - Sleep instead of delay during Airoha EN7581 power-up, since this is a non-atomic context (Lorenzo Bianconi) - Skip PERST# assertion on Airoha EN7581 during probe and suspend/resume to avoid a hardware defect (Lorenzo Bianconi) - Enable async probe to reduce system startup time (Douglas Anderson) Microchip PolarFlare PCIe controller driver: -

Pull kvm updates from Paolo Bonzini: "Loongarch: - Clear LLBCTL if secondary mmu mapping changes - Add hypercall service support for usermode VMM x86: - Add a comment to kvm_mmu_do_page_fault() to explain why KVM performs a direct call to kvm_tdp_page_fault() when RETPOLINE is enabled - Ensure that all SEV code is compiled out when disabled in Kconfig, even if building with less brilliant compilers - Remove a redundant TLB flush on AMD processors when guest CR4.PGE changes - Use str_enabled_disabled() to replace open coded strings - Drop kvm_x86_ops.hwapic_irr_update() as KVM updates hardware's APICv cache prior to every VM-Enter - Overhaul KVM's CPUID feature infrastructure to track all vCPU capabilities instead of just those where KVM needs to manage state and/or explicitly enable the feature in hardware. Along the way, refactor the code to make it easier to add features, and to make it more self-documenting how KVM is handling each feature - Rework KVM's handling of VM-Exits during event vectoring; this plugs holes where KVM unintentionally puts the vCPU into infinite loops in some scenarios (e.g. if emulation is triggered by the exit), and brings parity between VMX and SVM - Add pending request and interrupt injection information to the kvm_exit and kvm_entry tracepoints respectively - Fix a relatively benign flaw where KVM would end up redoing RDPKRU when loading guest/host PKRU, due to a refactoring of the kernel helpers that didn't account for KVM's pre-checking of the need to do WRPKRU - Make the completion of hypercalls go through the complete_hypercall function pointer argument, no matter if the hypercall exits to userspace or not. Previously, the code assumed that KVM_HC_MAP_GPA_RANGE specifically went to userspace, and all the others did not; the new code need not special case KVM_HC_MAP_GPA_RANGE and in fact does not care at all whether there was an exit to userspace or not - As part of enabling TDX virtual machines, support support separation of private/shared EPT into separate roots. When TDX will be enabled, operations on private pages will need to go through the privileged TDX Module via SEAMCALLs; as a result, they are limited and relatively slow compared to reading a PTE. The patches included in 6.14 allow KVM to keep a mirror of the private EPT in host memory, and define entries in kvm_x86_ops to operate on external page tables such as the TDX private EPT - The recently introduced conversion of the NX-page reclamation kthread to vhost_task moved the task under the main process. The task is created as soon as KVM_CREATE_VM was invoked and this, of course, broke userspace that didn't expect to see any child task of the VM process until it started creating its own userspace threads. In particular crosvm refuses to fork() if procfs shows any child task, so unbreak it by creating the task lazily. This is arguably a userspace bug, as there can be other kinds of legitimate worker tasks and they wouldn't impede fork(); but it's not like userspace has a way to distinguish kernel worker tasks right now. Should they show as "Kthread: 1" in proc/.../status? x86 - Intel: - Fix a bug where KVM updates hardware's APICv cache of the highest ISR bit while L2 is active, while ultimately results in a hardware-accelerated L1 EOI effectively being lost - Honor event priority when emulating Posted Interrupt delivery during nested VM-Enter by queueing KVM_REQ_EVENT instead of immediately handling the interrupt - Rework KVM's processing of the Page-Modification Logging buffer to reap entries in the same order they were created, i.e. to mark gfns dirty in the same order that hardware marked the page/PTE dirty - Misc cleanups Generic: - Cleanup and harden kvm_set_memory_region(); add proper lockdep assertions when setting memory regions and add a dedicated API for setting KVM-internal memory regions. The API can then explicitly disallow all flags for KVM-internal memory regions - Explicitly verify the target vCPU is online in kvm_get_vcpu() to fix a bug where KVM would return a pointer to a vCPU prior to it being fully online, and give kvm_for_each_vcpu() similar treatment to fix a similar flaw - Wait for a vCPU to come online prior to executing a vCPU ioctl, to fix a bug where userspace could coerce KVM into handling the ioctl on a vCPU that isn't yet onlined - Gracefully handle xarray insertion failures; even though such failures are impossible in practice after xa_reserve(), reserving an entry is always followed by xa_store() which does not know (or differentiate) whether there was an xa_reserve() before or not RISC-V: - Zabha, Svvptc, and Ziccrse extension support for guests. None of them require anything in KVM except for detecting them and marking them as supported; Zabha adds byte and halfword atomic operations, while the others are markers for specific operation of the TLB and of LL/SC instructions respectively - Virtualize SBI system suspend extension for Guest/VM - Support firmware counters which can be used by the guests to collect statistics about traps that occur in the host Selftests: - Rework vcpu_get_reg() to return a value instead of using an out-param, and update all affected arch code accordingly - Convert the max_guest_memory_test into a more generic mmu_stress_test. The basic gist of the "conversion" is to have the test do mprotect() on guest memory while vCPUs are accessing said memory, e.g. to verify KVM and mmu_notifiers are working as intended - Play nice with treewrite builds of unsupported architectures, e.g. arm (32-bit), as KVM selftests' Makefile doesn't do anything to ensure the target architecture is actually one KVM selftests supports - Use the kernel's $(ARCH) definition instead of the target triple for arch specific directories, e.g. arm64 instead of aarch64, mainly so as not to be different from the rest of the kernel - Ensure that format strings for logging statements are checked by the compiler even when the logging statement itself is disabled - Attempt to whack the last LLC references/misses mole in the Intel PMU counters test by adding a data load and doing CLFLUSH{OPT} on the data instead of the code being executed. It seems that modern Intel CPUs have learned new code prefetching tricks that bypass the PMU counters - Fix a flaw in the Intel PMU counters test where it asserts that events are counting correctly without actually knowing what the events count given the underlying hardware; this can happen if Intel reuses a formerly microarchitecture-specific event encoding as an architectural event, as was the case for Top-Down Slots" * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (151 commits) kvm: defer huge page recovery vhost task to later KVM: x86/mmu: Return RET_PF* instead of 1 in kvm_mmu_page_fault() KVM: Disallow all flags for KVM-internal memslots KVM: x86: Drop double-underscores from __kvm_set_memory_region() KVM: Add a dedicated API for setting KVM-internal memslots KVM: Assert slots_lock is held when setting memory regions KVM: Open code kvm_set_memory_region() into its sole caller (ioctl() API) LoongArch: KVM: Add hypercall service support for usermode VMM LoongArch: KVM: Clear LLBCTL if secondary mmu mapping is changed KVM: SVM: Use str_enabled_disabled() helper in svm_hardware_setup() KVM: VMX: read the PML log in the same order as it was written KVM: VMX: refactor PML terminology KVM: VMX: Fix comment of handle_vmx_instruction() KVM: VMX: Reinstate __exit attribute for vmx_exit() KVM: SVM: Use str_enabled_disabled() helper in sev_hardware_setup() KVM: x86: Avoid double RDPKRU when loading host/guest PKRU KVM: x86: Use LVT_TIMER instead of an open coded literal RISC-V: KVM: Add new exit statstics for redirected traps RISC-V: KVM: Update firmware counters for various events RISC-V: KVM: Redirect instruction access fault trap to guest ...

git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs Pull fsnotify pre-content notification support from Jan Kara: "This introduces a new fsnotify event (FS_PRE_ACCESS) that gets generated before a file contents is accessed. The event is synchronous so if there is listener for this event, the kernel waits for reply. On success the execution continues as usual, on failure we propagate the error to userspace. This allows userspace to fill in file content on demand from slow storage. The context in which the events are generated has been picked so that we don't hold any locks and thus there's no risk of a deadlock for the userspace handler. The new pre-content event is available only for users with global CAP_SYS_ADMIN capability (similarly to other parts of fanotify functionality) and it is an administrator responsibility to make sure the userspace event handler doesn't do stupid stuff that can DoS the system. Based on your feedback from the last submission, fsnotify code has been improved and now file->f_mode encodes whether pre-content event needs to be generated for the file so the fast path when nobody wants pre-content event for the file just grows the additional file->f_mode check. As a bonus this also removes the checks whether the old FS_ACCESS event needs to be generated from the fast path. Also the place where the event is generated during page fault has been moved so now filemap_fault() generates the event if and only if there is no uptodate folio in the page cache. Also we have dropped FS_PRE_MODIFY event as current real-world users of the pre-content functionality don't really use it so let's start with the minimal useful feature set" * tag 'fsnotify_hsm_for_v6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: (21 commits) fanotify: Fix crash in fanotify_init(2) fs: don't block write during exec on pre-content watched files fs: enable pre-content events on supported file systems ext4: add pre-content fsnotify hook for DAX faults btrfs: disable defrag on pre-content watched files xfs: add pre-content fsnotify hook for DAX faults fsnotify: generate pre-content permission event on page fault mm: don't allow huge faults for files with pre content watches fanotify: disable readahead if we have pre-content watches fanotify: allow to set errno in FAN_DENY permission response fanotify: report file range info with pre-content events fanotify: introduce FAN_PRE_ACCESS permission event fsnotify: generate pre-content permission event on truncate fsnotify: pass optional file access range in pre-content event fsnotify: introduce pre-content permission events fanotify: reserve event bit of deprecated FAN_DIR_MODIFY fanotify: rename a misnamed constant fanotify: don't skip extra event info if no info_mode is set fsnotify: check if file is actually being watched for pre-content events on open fsnotify: opt-in for permission events at file open time ...
