Linus Torvalds	9f16d5e6f2	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. -----BEGIN PGP SIGNATURE----- iQFIBAABCAAyFiEE8TM4V0tmI4mGbHaCv/vSX3jHroMFAmc9MRYUHHBib256aW5p QHJlZGhhdC5jb20ACgkQv/vSX3jHroP00QgArxqxBIGLCW5t7bw7vtNq63QYRyh4 dTiDguLiYQJ+AXmnRu11R6aPC7HgMAvlFCCmH+GEce4WEgt26hxCmncJr/aJOSwS letCS7TrME16PeZvh25A1nhPBUw6mTF1qqzgcdHMrqXG8LuHoGcKYGSRVbkf3kfI 1ZoMq1r8ChXbVVmCx9DQ3gw1TVr5Dpjs2voLh8rDSE9Xpw0tVVabHu3/NhQEz/F+ t8/nRaqH777icCHIf9PCk5HnarHxLAOvhM2M0Yj09PuBcE5fFQxpxltw/qiKQqqW ep4oquojGl87kZnhlDaac2UNtK90Ws+WxxvCwUmbvGN0ZJVaQwf4FvTwig== =lWpE -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull kvm updates from Paolo Bonzini: "The biggest change here is eliminating the awful idea that KVM had of essentially guessing which pfns are refcounted pages.

Linus Torvalds	341d041daa	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.

Linus Torvalds	fcc79e1714	Networking changes for 6.13. ... The most significant set of changes is the per netns RTNL. The new behavior is disabled by default, regression risk should be contained. Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its default value from PTP_1588_CLOCK_KVM, as the first is intended to be a more reliable replacement for the latter. Core ---- - Started a very large, in-progress, effort to make the RTNL lock scope per network-namespace, thus reducing the lock contention significantly in the containerized use-case, comprising: - RCU-ified some relevant slices of the FIB control path - introduce basic per netns locking helpers - namespacified the IPv4 address hash table - remove rtnl_register{,_module}() in favour of rtnl_register_many() - refactor rtnl_{new,del,set}link() moving as much validation as possible out of RTNL lock - convert all phonet doit() and dumpit() handlers to RCU - convert IPv4 addresses manipulation to per-netns RTNL - convert virtual interface creation to per-netns RTNL the per-netns lock infra is guarded by the CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim. - Introduce NAPI suspension, to efficiently switching between busy polling (NAPI processing suspended) and normal processing. - Migrate the IPv4 routing input, output and control path from direct ToS usage to DSCP macros. This is a work in progress to make ECN handling consistent and reliable. - Add drop reasons support to the IPv4 rotue input path, allowing better introspection in case of packets drop. - Make FIB seqnum lockless, dropping RTNL protection for read access. - Make inet{,v6} addresses hashing less predicable. - Allow providing timestamp OPT_ID via cmsg, to correlate TX packets and timestamps Things we sprinkled into general kernel code -------------------------------------------- - Add small file operations for debugfs, to reduce the struct ops size. - Refactoring and optimization for the implementation of page_frag API, This is a preparatory work to consolidate the page_frag implementation. Netfilter --------- - Optimize set element transactions to reduce memory consumption - Extended netlink error reporting for attribute parser failure. - Make legacy xtables configs user selectable, giving users the option to configure iptables without enabling any other config. - Address a lot of false-positive RCU issues, pointed by recent CI improvements. BPF --- - Put xsk sockets on a struct diet and add various cleanups. Overall, this helps to bump performance by 12% for some workloads. - Extend BPF selftests to increase coverage of XDP features in combination with BPF cpumap. - Optimize and homogenize bpf_csum_diff helper for all archs and also add a batch of new BPF selftests for it. - Extend netkit with an option to delegate skb->{mark,priority} scrubbing to its BPF program. - Make the bpf_get_netns_cookie() helper available also to tc(x) BPF programs. Protocols --------- - Introduces 4-tuple hash for connected udp sockets, speeding-up significantly connected sockets lookup. - Add a fastpath for some TCP timers that usually expires after close, the socket lock contention. - Add inbound and outbound xfrm state caches to speed up state lookups. - Avoid sending MPTCP advertisements on stale subflows, reducing risks on loosing them. - Make neighbours table flushing more scalable, maintaining per device neigh lists. Driver API ---------- - Introduce a unified interface to configure transmission H/W shaping, and expose it to user-space via generic-netlink. - Add support for per-NAPI config via netlink. This makes napi configuration persistent across queues removal and re-creation. Requires driver updates, currently supported drivers are: nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice. - Add ethtool support for writing SFP / PHY firmware blocks. - Track RSS context allocation from ethtool core. - Implement support for mirroring to DSA CPU port, via TC mirror offload. - Consolidate FDB updates notification, to avoid duplicates on device-specific entries. - Expose DPLL clock quality level to the user-space. - Support master-slave PHY config via device tree. Tests and tooling ----------------- - forwarding: introduce deferred commands, to simplify the cleanup phase Drivers ------- - Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic, Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the IRQs and queues to NAPI IDs, allowing busy polling and better introspection. - Ethernet high-speed NICs: - nVidia/Mellanox: - mlx5: - a large refactor to implement support for cross E-Switch scheduling - refactor H/W conter management to let it scale better - H/W GRO cleanups - Intel (100G, ice):: - adds support for ethtool reset - implement support for per TX queue H/W shaping - AMD/Solarflare: - implement per device queue stats support - Broadcom (bnxt): - improve wildcard l4proto on IPv4/IPv6 ntuple rules - Marvell Octeon: - Adds representor support for each Resource Virtualization Unit (RVU) device. - Hisilicon: - adds support for the BMC Gigabit Ethernet - IBM (EMAC): - driver cleanup and modernization - Cisco (VIC): - raise the queues number limit to 256 - Ethernet virtual: - Google vNIC: - implements page pool support - macsec: - inherit lower device's features and TSO limits when offloading - virtio_net: - enable premapped mode by default - support for XDP socket(AF_XDP) zerocopy TX - wireguard: - set the TSO max size to be GSO_MAX_SIZE, to aggregate larger packets. - Ethernet NICs embedded and virtual: - Broadcom ASP: - enable software timestamping - Freescale: - add enetc4 PF driver - MediaTek: Airoha SoC: - implement BQL support - RealTek r8169: - enable TSO by default on r8168/r8125 - implement extended ethtool stats - Renesas AVB: - enable TX checksum offload - Synopsys (stmmac): - support header splitting for vlan tagged packets - move common code for DWMAC4 and DWXGMAC into a separate FPE module. - Add the dwmac driver support for T-HEAD TH1520 SoC - Synopsys (xpcs): - driver refactor and cleanup - TI: - icssg_prueth: add VLAN offload support - Xilinx emaclite: - adds clock support - Ethernet switches: - Microchip: - implement support for the lan969x Ethernet switch family - add LAN9646 switch support to KSZ DSA driver - Ethernet PHYs: - Marvel: 88q2x: enable auto negotiation - Microchip: add support for LAN865X Rev B1 and LAN867X Rev C1/C2 - PTP: - Add support for the Amazon virtual clock device - Add PtP driver for s390 clocks - WiFi: - mac80211 - EHT 1024 aggregation size for transmissions - new operation to indicate that a new interface is to be added - support radio separation of multi-band devices - move wireless extension spy implementation to libiw - Broadcom: - brcmfmac: optional LPO clock support - Microchip: - add support for Atmel WILC3000 - Qualcomm (ath12k): - firmware coredump collection support - add debugfs support for a multitude of statistics - Qualcomm (ath5k): - Arcadyan ARV45XX AR2417 & Gigaset SX76[23] AR241[34]A support - Realtek: - rtw88: 8821au and 8812au USB adapters support - rtw89: add thermal protection - rtw89: fine tune BT-coexsitence to improve user experience - rtw89: firmware secure boot for WiFi 6 chip - Bluetooth - add Qualcomm WCN785x support for ids Foxconn 0xe0fc/0xe0f3 and 0x13d3:0x3623 - add Realtek RTL8852BE support for id Foxconn 0xe123 - add MediaTek MT7920 support for wireless module ids - btintel_pcie: add handshake between driver and firmware - btintel_pcie: add recovery mechanism - btnxpuart: add GPIO support to power save feature Signed-off-by: Paolo Abeni <pabeni@redhat.com> -----BEGIN PGP SIGNATURE----- iQJGBAABCAAwFiEEg1AjqC77wbdLX2LbKSR5jcyPE6QFAmc8sukSHHBhYmVuaUBy ZWRoYXQuY29tAAoJECkkeY3MjxOkLEYQAIMM6Qjh0bh3Byr3gOS1xZzXG+APLjP4 9Jr0p3i+X53i90jvVqzeVO5FTc95MVHSKZ3kvPkDMXSLUaEJxocNHCI5Dzl/2/qL wWdpUB6/ou+jKB4Bn6Z8OvVODT7qrr0tVa9M2/fuKWrIsOU/ntIhG8EhnGddk5U/ vKPSf5PUIb81uNRnF58VusY3wrT1dEoh9VfJYxL+ST+inPxjEAMy6Y+lmlsjGaSX jrS+Pp9KYiUwl3Qt0AQs+cG4OHkJdjbnChrfosWwpkiyddO8klVq06+wX/TiSzfF b9VZtBfy/GZs3lkE1mQkcILdtX5pP3YHQdpsuxFfVI0JHVszx2ck7WdoRux/8F0v kKZsYcO7bH9I1wMFP66Ff9hIbdEQaeucK+KdDkXyPNMfP91Vzmfjii8IBxOC36Ie BbOeFUrXyTxxJ2u0vf/X9JtIq8bcrkNrSd1n1jlGPMqG3FVzsY95+Oi4qfsyeUbl lS1PlVTqPMPFdX54HnxM3y2rJjhd7iXhkvmtuXNjRFThXlOiK3maAPWlM1aZ3b8u Vjs4JFUsW0tleZG+RzANjsGjXbf7AiPUGLZt+acem0K+fcjG4i5aGIAJrxwa/ORx eG74IZRt5cOI371W7gNLGHjwnuge8tFPgOWcRP2eozNm7jvMYALBejYS7eWUTvaf THcvVM+bupEZ =GzPr -----END PGP SIGNATURE----- Merge tag 'net-next-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "The most significant set of changes is the per netns RTNL.

Linus Torvalds	bf9aa14fc5	A rather large update for timekeeping and timers: ... - The final step to get rid of auto-rearming posix-timers posix-timers are currently auto-rearmed by the kernel when the signal of the timer is ignored so that the timer signal can be delivered once the corresponding signal is unignored. This requires to throttle the timer to prevent a DoS by small intervals and keeps the system pointlessly out of low power states for no value. This is a long standing non-trivial problem due to the lock order of posix-timer lock and the sighand lock along with life time issues as the timer and the sigqueue have different life time rules. Cure this by: * Embedding the sigqueue into the timer struct to have the same life time rules. Aside of that this also avoids the lookup of the timer in the signal delivery and rearm path as it's just a always valid container_of() now. * Queuing ignored timer signals onto a seperate ignored list. * Moving queued timer signals onto the ignored list when the signal is switched to SIG_IGN before it could be delivered. * Walking the ignored list when SIG_IGN is lifted and requeue the signals to the actual signal lists. This allows the signal delivery code to rearm the timer. This also required to consolidate the signal delivery rules so they are consistent across all situations. With that all self test scenarios finally succeed. - Core infrastructure for VFS multigrain timestamping This is required to allow the kernel to use coarse grained time stamps by default and switch to fine grained time stamps when inode attributes are actively observed via getattr(). These changes have been provided to the VFS tree as well, so that the VFS specific infrastructure could be built on top. - Cleanup and consolidation of the sleep() infrastructure * Move all sleep and timeout functions into one file * Rework udelay() and ndelay() into proper documented inline functions and replace the hardcoded magic numbers by proper defines. * Rework the fsleep() implementation to take the reality of the timer wheel granularity on different HZ values into account. Right now the boundaries are hard coded time ranges which fail to provide the requested accuracy on different HZ settings. * Update documentation for all sleep/timeout related functions and fix up stale documentation links all over the place * Fixup a few usage sites - Rework of timekeeping and adjtimex(2) to prepare for multiple PTP clocks A system can have multiple PTP clocks which are participating in seperate and independent PTP clock domains. So far the kernel only considers the PTP clock which is based on CLOCK TAI relevant as that's the clock which drives the timekeeping adjustments via the various user space daemons through adjtimex(2). The non TAI based clock domains are accessible via the file descriptor based posix clocks, but their usability is very limited. They can't be accessed fast as they always go all the way out to the hardware and they cannot be utilized in the kernel itself. As Time Sensitive Networking (TSN) gains traction it is required to provide fast user and kernel space access to these clocks. The approach taken is to utilize the timekeeping and adjtimex(2) infrastructure to provide this access in a similar way how the kernel provides access to clock MONOTONIC, REALTIME etc. Instead of creating a duplicated infrastructure this rework converts timekeeping and adjtimex(2) into generic functionality which operates on pointers to data structures instead of using static variables. This allows to provide time accessors and adjtimex(2) functionality for the independent PTP clocks in a subsequent step. - Consolidate hrtimer initialization hrtimers are set up by initializing the data structure and then seperately setting the callback function for historical reasons. That's an extra unnecessary step and makes Rust support less straight forward than it should be. Provide a new set of hrtimer_setup*() functions and convert the core code and a few usage sites of the less frequently used interfaces over. The bulk of the htimer_init() to hrtimer_setup() conversion is already prepared and scheduled for the next merge window. - Drivers: * Ensure that the global timekeeping clocksource is utilizing the cluster 0 timer on MIPS multi-cluster systems. Otherwise CPUs on different clusters use their cluster specific clocksource which is not guaranteed to be synchronized with other clusters. * Mostly boring cleanups, fixes, improvements and code movement -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmc7kPITHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoZKkD/9OUL6fOJrDUmOYBa4QVeMyfTef4EaL tvwIMM/29XQFeiq3xxCIn+EMnHjXn2lvIhYGQ7GKsbKYwvJ7ZBDpQb+UMhZ2nKI9 6D6BP6WomZohKeH2fZbJQAdqOi3KRYdvQdIsVZUexkqiaVPphRvOH9wOr45gHtZM EyMRSotPlQTDqcrbUejDMEO94GyjDCYXRsyATLxjmTzL/N4xD4NRIiotjM2vL/a9 8MuCgIhrKUEyYlFoOxxeokBsF3kk3/ez2jlG9b/N8VLH3SYIc2zgL58FBgWxlmgG bY71nVG3nUgEjxBd2dcXAVVqvb+5widk8p6O7xxOAQKTLMcJ4H0tQDkMnzBtUzvB DGAJDHAmAr0g+ja9O35Pkhunkh4HYFIbq0Il4d1HMKObhJV0JumcKuQVxrXycdm3 UZfq3seqHsZJQbPgCAhlFU0/2WWScocbee9bNebGT33KVwSp5FoVv89C/6Vjb+vV Gusc3thqrQuMAZW5zV8g4UcBAA/xH4PB0I+vHib+9XPZ4UQ7/6xKl2jE0kd5hX7n AAUeZvFNFqIsY+B6vz+Jx/yzyM7u5cuXq87pof5EHVFzv56lyTp4ToGcOGYRgKH5 JXeYV1OxGziSDrd5vbf9CzdWMzqMvTefXrHbWrjkjhNOe8E1A8O88RZ5uRKZhmSw hZZ4hdM9+3T7cg== =2VC6 -----END PGP SIGNATURE----- Merge tag 'timers-core-2024-11-18' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "A rather large update for timekeeping and timers: - The final step to get rid of auto-rearming posix-timers posix-timers are currently auto-rearmed by the kernel when the signal of the timer is ignored so that the timer signal can be delivered once the corresponding signal is unignored.

Kees Cook	96c677fca5	UAPI: ethtool: Avoid flex-array in struct ethtool_link_settings ... struct ethtool_link_settings tends to be used as a header for other structures that have trailing bytes[1], but has a trailing flexible array itself. Using this overlapped with other structures leads to ambiguous object sizing in the compiler, so we want to avoid such situations (which have caused real bugs in the past). Detecting this can be done with -Wflex-array-member-not-at-end, which will need to be enabled globally. Using a tagged struct_group() to create a new ethtool_link_settings_hdr structure isn't possible as it seems we cannot use the tagged variant of struct_group() due to syntax issues from C++'s perspective (even within "extern C")[2]. Instead, we can just leave the offending member defined in UAPI and remove it from the kernel's view of the structure, as Linux doesn't actually use this member at all. There is also no change in size since it was already a flexible array that didn't contribute to size returned by any use of sizeof().

It can be hard to appropriately size the CQ ring upfront, if the application doesn't know how busy it will be. This results in applications sizing rings for the most busy case, which can be wasteful. With ring resizing, they can start small and grow the ring, if needed. - Add support for fixed wait regions, rather than needing to copy the same wait data tons of times for each wait operation. - Rewrite the resource node handling, which before was serialized per ring. This caused issues with particularly fixed files, where one file waiting on IO could hold up putting and freeing of other unrelated files. Now each node is handled separately. New code is much simpler too, and was a net 250 line reduction in code. - Add support for just doing partial buffer clones, rather than always cloning the entire buffer table. - Series adding static NAPI support, where a specific NAPI instance is used rather than having a list of them available that need lookup. - Add support for mapped regions, and also convert the fixed wait support mentioned above to that concept. This avoids doing special mappings for various planned features, and folds the existing registered wait into that too. - Add support for hybrid IO polling, which is a variant of strict IOPOLL but with an initial sleep delay to avoid spinning too early and wasting resources on devices that aren't necessarily in the < 5 usec category wrt latencies. - Various cleanups and little fixes. * tag 'for-6.13/io_uring-20241118' of git://git.kernel.dk/linux: (79 commits) io_uring/region: fix error codes after failed vmap io_uring: restore back registered wait arguments io_uring: add memory region registration io_uring: introduce concept of memory regions io_uring: temporarily disable registered waits io_uring: disable ENTER_EXT_ARG_REG for IOPOLL io_uring: fortify io_pin_pages with a warning switch io_msg_ring() to CLASS(fd) io_uring: fix invalid hybrid polling ctx leaks io_uring/uring_cmd: fix buffer index retrieval io_uring/rsrc: add & apply io_req_assign_buf_node() io_uring/rsrc: remove '->ctx_ptr' of 'struct io_rsrc_node' io_uring/rsrc: pass 'struct io_ring_ctx' reference to rsrc helpers io_uring: avoid normal tw intermediate fallback io_uring/napi: add static napi tracking strategy io_uring/napi: clean up __io_napi_do_busy_loop io_uring/napi: Use lock guards io_uring/napi: improve __io_napi_add io_uring/napi: fix io_napi_entry RCU accesses io_uring/napi: protect concurrent io_napi_entry timeout accesses ...	2024-11-18 17:02:57 -08:00

A common pattern when using pidfds is having to get information about the process, which currently requires /proc being mounted, resolving the fd to a pid, and then do manual string parsing of /proc/N/status and friends. This needs to be reimplemented over and over in all userspace projects (e.g.: it has been reimplemented in systemd, dbus, dbus-daemon, polkit so far), and requires additional care in checking that the fd is still valid after having parsed the data, to avoid races. Having a programmatic API that can be used directly removes all these requirements, including having /proc mounted. As discussed at LPC24, add an ioctl with an extensible struct so that more parameters can be added later if needed.

Unfortunately, part of that work caused both NLM (for NFS v3 exports) and kNFSD (for NFSv4.1+ exports) to no longer send lock notifications to clients This in itself is not a huge problem because most NFS clients will still poll the server in order to acquire a conflicted lock It's important for NLM and kNFSD that they do not block their kernel threads inside filesystem's file_lock implementations because that can produce deadlocks. We used to make sure of this by only trusting that posix_lock_file() can correctly handle blocking lock calls asynchronously, so the lock managers would only setup their file_lock requests for async callbacks if the filesystem did not define its own lock() file operation However, when GFS2 and OCFS2 grew the capability to correctly handle blocking lock requests asynchronously, they started signalling this behavior with EXPORT_OP_ASYNC_LOCK, and the check for also trusting posix_lock_file() was inadvertently dropped, so now most filesystems no longer produce lock notifications when exported over NFS Fix this by using an fop_flag which greatly simplifies the problem and grooms the way for future uses by both filesystems and lock managers alike - Add a sysctl to delete the dentry when a file is removed instead of making it a negative dentry Commit 681ce86235 ("vfs: Delete the associated dentry when deleting a file") introduced an unconditional deletion of the associated dentry when a file is removed. However, this led to performance regressions in specific benchmarks, such as ilebench.sum_operations/s, prompting a revert in commit 4a4be1ad3a ("Revert "vfs: Delete the associated dentry when deleting a file""). This reintroduces the concept conditionally through a sysctl - Expand the statmount() system call: * Report the filesystem subtype in a new fs_subtype field to e.g., report fuse filesystem subtypes * Report the superblock source in a new sb_source field * Add a new way to return filesystem specific mount options in an option array that returns filesystem specific mount options separated by zero bytes and unescaped. This allows caller's to retrieve filesystem specific mount options and immediately pass them to e.g., fsconfig() without having to unescape or split them * Report security (LSM) specific mount options in a separate security option array. We don't lump them together with filesystem specific mount options as security mount options are generic and most users aren't interested in them The format is the same as for the filesystem specific mount option array - Support relative paths in fsconfig()'s FSCONFIG_SET_STRING command - Optimize acl_permission_check() to avoid costly {g,u}id ownership checks if possible - Use smp_mb__after_spinlock() to avoid full smp_mb() in evict() - Add synchronous wakeup support for ep_poll_callback. Currently, epoll only uses wake_up() to wake up task. But sometimes there are epoll users which want to use the synchronous wakeup flag to give a hint to the scheduler, e.g., the Android binder driver. So add a wake_up_sync() define, and use wake_up_sync() when sync is true in ep_poll_callback() Fixes: - Fix kernel documentation for inode_insert5() and iget5_locked() - Annotate racy epoll check on file->f_ep - Make F_DUPFD_QUERY associative - Avoid filename buffer overrun in initramfs - Don't let statmount() return empty strings - Add a cond_resched() to dump_user_range() to avoid hogging the CPU - Don't query the device logical blocksize multiple times for hfsplus - Make filemap_read() check that the offset is positive or zero Cleanups: - Various typo fixes - Cleanup wbc_attach_fdatawrite_inode() - Add __releases annotation to wbc_attach_and_unlock_inode() - Add hugetlbfs tracepoints - Fix various vfs kernel doc parameters - Remove obsolete TODO comment from io_cancel() - Convert wbc_account_cgroup_owner() to take a folio - Fix comments for BANDWITH_INTERVAL and wb_domain_writeout_add() - Reorder struct posix_acl to save 8 bytes - Annotate struct posix_acl with __counted_by() - Replace one-element array with flexible array member in freevxfs - Use idiomatic atomic64_inc_return() in alloc_mnt_ns()" * tag 'vfs-6.13.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (35 commits) statmount: retrieve security mount options vfs: make evict() use smp_mb__after_spinlock instead of smp_mb statmount: add flag to retrieve unescaped options fs: add the ability for statmount() to report the sb_source writeback: wbc_attach_fdatawrite_inode out of line writeback: add a __releases annoation to wbc_attach_and_unlock_inode fs: add the ability for statmount() to report the fs_subtype fs: don't let statmount return empty strings fs:aio: Remove TODO comment suggesting hash or array usage in io_cancel() hfsplus: don't query the device logical block size multiple times freevxfs: Replace one-element array with flexible array member fs: optimize acl_permission_check() initramfs: avoid filename buffer overrun fs/writeback: convert wbc_account_cgroup_owner to take a folio acl: Annotate struct posix_acl with __counted_by() acl: Realign struct posix_acl to save 8 bytes epoll: Add synchronous wakeup support for ep_poll_callback coredump: add cond_resched() to dump_user_range mm/page-writeback.c: Fix comment of wb_domain_writeout_add() mm/page-writeback.c: Update comment for BANDWIDTH_INTERVAL ...	2024-11-18 09:35:30 -08:00

Pavel Begunkov	d617b3147d	io_uring: restore back registered wait arguments ... Now we've got a more generic region registration API, place IORING_ENTER_EXT_ARG_REG and re-enable it. First, the user has to register a region with the IORING_MEM_REGION_REG_WAIT_ARG flag set. It can only be done for a ring in a disabled state, aka IORING_SETUP_R_DISABLED, to avoid races with already running waiters. With that we should have stable constant values for ctx->cq_wait_{size,arg} in io_get_ext_arg_reg() and hence no READ_ONCE required. The other API difference is that we're now passing byte offsets instead of indexes. The user _must_ align all offsets / pointers to the native word size, failing to do so might but not necessarily has to lead to a failure usually returned as -EFAULT. liburing will be hiding this details from users.

Pavel Begunkov	93238e6618	io_uring: add memory region registration ... Regions will serve multiple purposes. First, with it we can decouple ring/etc. object creation from registration / mapping of the memory they will be placed in. We already have hacks that allow to put both SQ and CQ into the same huge page, in the future we should be able to: region = create_region(io_ring); create_pbuf_ring(io_uring, region, offset=0); create_pbuf_ring(io_uring, region, offset=N); The second use case is efficiently passing parameters. The following patch enables back on top of regions IORING_ENTER_EXT_ARG_REG, which optimises wait arguments. It'll also be useful for request arguments replacing iovecs, msghdr, etc. pointers. Eventually it would also be handy for BPF as well if it comes to fruition.

Pavel Begunkov	dfbbfbf191	io_uring: introduce concept of memory regions ... We've got a good number of mappings we share with the userspace, that includes the main rings, provided buffer rings, upcoming rings for zerocopy rx and more. All of them duplicate user argument parsing and some internal details as well (page pinnning, huge page optimisations, mmap'ing, etc.) Introduce a notion of regions. For userspace for now it's just a new structure called struct io_uring_region_desc which is supposed to parameterise all such mapping / queue creations. A region either represents a user provided chunk of memory, in which case the user_addr field should point to it, or a request for the kernel to allocate the memory, in which case the user would need to mmap it after using the offset returned in the mmap_offset field. With a uniform userspace API we can avoid additional boiler plate code and apply future optimisation to all of them at once. Internally, there is a new structure struct io_mapped_region holding all relevant runtime information and some helpers to work with it. This patch limits it to user provided regions.

This will be used for live update, allowing an old process to hand the iommufd device descriptor to a new process. The new process calls the ioctl. IOMMU_IOAS_CHANGE_PROCESS only supports DMA mappings created with IOMMU_IOAS_MAP_FILE, because the kernel metadata for such mappings does not depend on the userland VA of the pages (which is different in the new process). IOMMU_IOAS_CHANGE_PROCESS fails if other types of mappings are present. This is a revised version of code originally provided by Jason.

Stefan Berger	95f567f81e	fs: Simplify getattr interface function checking AT_GETATTR_NOSEC flag ... Commit 8a924db2d7 ("fs: Pass AT_GETATTR_NOSEC flag to getattr interface function")' introduced the AT_GETATTR_NOSEC flag to ensure that the call paths only call vfs_getattr_nosec if it is set instead of vfs_getattr. Now, simplify the getattr interface functions of filesystems where the flag AT_GETATTR_NOSEC is checked. There is only a single caller of inode_operations getattr function and it is located in fs/stat.c in vfs_getattr_nosec. The caller there is the only one from which the AT_GETATTR_NOSEC flag is passed from. Two filesystems are checking this flag in .getattr and the flag is always passed to them unconditionally from only vfs_getattr_nosec: - ecryptfs: Simplify by always calling vfs_getattr_nosec in ecryptfs_getattr. From there the flag is passed to no other function and this function is not called otherwise. - overlayfs: Simplify by always calling vfs_getattr_nosec in ovl_getattr. From there the flag is passed to no other function and this function is not called otherwise. The query_flags in vfs_getattr_nosec will mask-out AT_GETATTR_NOSEC from any caller using AT_STATX_SYNC_TYPE as mask so that the flag is not important inside this function. Also, since no filesystem is checking the flag anymore, remove the flag entirely now, including the BUG_ON check that never triggered. The net change of the changes here combined with the original commit is that ecryptfs and overlayfs do not call vfs_getattr but only vfs_getattr_nosec.

Miklos Szeredi	2f4d4503e9	statmount: add flag to retrieve unescaped options ...
