Important updates

Kernel updates

  • New features

    • Core scheduling is supported.

      The core scheduling security feature that is released by the upstream community is backported. This feature allows trusted processes only in the same group to run on the hyper threads of the same physical core. This feature is incompatible with the group identity feature. Do not enable the features at the same time. By default, this feature is disabled. To enable this feature, run the sysctl -w kernel.sched_core=1 command.

    • The extended Berkeley Packet Filter (eBPF) trampoline feature is supported on the Arm 64-bit architecture.

      The eBPF trampoline feature is backported on the Arm 64-bit architecture to support the Berkeley Packet Filter (BPF) struct_ops feature. The BPF fentry series features are unavailable because they are not backported on the Arm 64-bit architecture.

    • The Multi-Generational Least Recently Used (MGLRU) feature is supported.

      The MGLRU feature supports memory page reclaim with improved performance. This way, the speed and accuracy of memory reclaim in big data scenarios are increased, and E2E performance is improved.

    • Batch translation lookaside buffer (TLB) flushing is supported.

      The batch migration feature uses batch TLB flushing and page copying during memory page migration to improve the performance of kernel page migration operations.

      The current batch migration feature is a refactored version that is optimized from the previous version in the kernel based on the upstream code. Main changes: The batch_migrate parameter is removed from cmdline, the /sys/kernel/mm/migrate/batch_migrate_enabled interface is removed, and batch migration becomes the default configuration used during page migration.

      The /sys/kernel/mm/migrate/dma_migration_min_pages interface is added. Default value: 32. This interface applies only to scenarios where the Direct Memory Access (DMA) page copy feature is enabled. The DMA page copy feature is used only when the /sys/kernel/mm/migrate/dma_migrate_enabled parameter is set to enabled and the number of migrate pages reaches the /sys/kernel/mm/migrate/dma_migration_min_pages value.

    • The cachestat feature is backported.

      The cachestat system call is introduced in the kernel. This allows you to view detailed page cache statistics about a specific file.

    • Arm 64 kernel-mode Reliability, Availability, and Serviceability (RAS) events are enhanced.

      The abilities of recovering from RAS errors in different scenarios are supported, such as copy_{from/to}_user, {get/put}_user, copy-on-write (COW), and pagecache read.

    • The in-house Shared Memory Communication-Direct Memory Access (SMC-D) loopback feature is supported.

      The SMC-D loopback feature is introduced to accelerate TCP communication between local processes and between containers.

    • The in-house page table binding feature is supported and provides cross-die statistics on page tables.

      The ability of binding page tables to cores is provided to allocate the page tables of QoS-sensitive services to the current Non-Uniform Memory Access (NUMA) node as much as possible when the memory is insufficient. This feature helps reduce the memory access latency and implement more efficient memory access.

    • The in-house duptext feature is enhanced.

      An asynchronous task can be used to make another attempt if multiple copies of the code do not take effect on process startup. The memory.duptext_nodes kernel interface is added to limit the duptext memory allocation nodes.

    • The in-house Kernel Electric-Fence (KFENCE) enhancements are added.

      • The in-house KFENCE enhancement feature is added on the Arm 64-bit architecture. This feature can flexibly and dynamically enable or disable KFENCE to fully capture memory pollution problems. This facilitates online detection and offline debugging.

      • The immediate downtime feature is added to trigger downtime as soon as a memory issue is detected, to help developers better analyze problems in a debugging environment. You can enable this feature by specifying the boot cmdline "kfence.fault=panic" or echo panic > /sys/module/kfence/parameters/fault parameter. The default value is report, which indicates that the system only displays logs without downtime.

    • The in-house control interface is provided for memcg Transparent Huge Pages (THPs).

      The memcg THP control interface is used to prohibit the application of a specific memcg THP.

    • The in-house Assess CPU (ACPU) is supported.

      The ACPU can count the peer HT idle time of a task during the runtime and provide per-cgroup statistics, which can be used to evaluate the hardware resource competition on shared CPUs during the task runtime.

    • The in-house HT-aware-quota feature is supported.

      The computing power stabilization solution based on Completely Fair Scheduler (CFS) bandwidth control and core scheduling can calibrate quotas by checking whether the HT peer is idle in hybrid deployment scenarios. This way, tasks can obtain relatively stable computing power in each scheduling cycle. The solution is suitable for compute-intensive tasks.

    • In-house group identity 2.0 is supported.

      The SCHED_IDLE feature is provided for cgroups. You can set the cpu.idle property of a cgroup to use the SCHED_IDLE scheduling policy for the cgroup. This feature is suitable for batch management of offline tasks.

  • Behavior changes

    • The module signature feature is added.

      Signatures are added to kernel modules to help developers identify and reject unsigned kernel modules.

    • By default, mitigations for the Spectre-BHB and Variant 4 vulnerabilities are disabled on the Arm 64-bit architecture.

      The Spectre-BHB and Variant 4 vulnerabilities are fixed when you fix the Spectre V2 vulnerability, disable the unprivileged eBPF or Site Isolation technology, or disable the SharedArrayBuffer object. You do not need to separately fix the Spectre-BHB and Variant 4 vulnerabilities. By default, on the Arm 64-bit architecture, the nospectre_bhb ssbd=force-off parameter is added to cmdline to disable mitigations for the Spectre-BHB and Variant4 vulnerabilities to improve performance.

    • Trust Domain Extensions (TDX) guest-related configurations are added to support TDX confidential virtual machine (VM) scenarios.

New software package features

  • Provision of erofs-utils-1.7.1 by using software repositories

    The erofs-utils tool is used to create, check, and compress Enhanced Read-Only File System (EROFS). This tool supports compression algorithms such as LZ4, Lempel–Ziv–Markov chain algorithm (LZMA), and DEFLATE, and supports tar-to-erofs format conversion.

  • Provision of stress-ng-0.15.00 by using software repositories

  • Provision of alibaba-cloud-compiler-13.0.1.4 by using software repositories

    Alibaba Cloud Compiler is a C/C++ compiler developed by Alibaba Cloud based on the open source version from the Clang/LLVM-13 community. Alibaba Cloud Compiler inherits all options and parameters supported in the open source version. In addition, Alibaba Cloud Compiler is deeply optimized based on the Alibaba Cloud infrastructure and provides unique features and optimizations to make the C/C++ compiler better for Alibaba Cloud users.

  • glibc is patched to support GB18030-2022 coding.

  • Dragonwell17 is updated to 17.0.9.0.10.9. In the just-in-time compilation (JIT) compiler, inlining performance is improved, and the judgment logic of inline based on the number of absolute calls is removed.

  • Dragonwell8 is updated to 8.15.16.372. Multiple coroutines can wait for the read and write events of the same socket, and bugs in the okhttp scenario are fixed.

  • Provision of plugsched-1.3 by using software repositories

    Plugsched is an SDK that supports the live update of the Linux kernel scheduler. Plugsched is intended for kernel scheduler developers. You can install plugsched to develop scheduler modules.

  • Sysak is updated to 2.2.0. The application observation feature is added to support the metric observation and diagnostics of MySQL and Java applications. The metrics related to container monitoring and cluster monitoring are added. The local monitoring feature is added.

  • Keentune is updated to 2.3.0. x264/265-related scripts are updated to support the latest FFmpeg. The issue of binding errors of Transmit Packet Steering (XPS) and Receive Packet Steering (RPS) is fixed. The default elastic Remote Direct Memory Access (eRDMA) settings in profile are updated.

  • The software chain of the Intel QuickAssist (QAT), Dynamic Load Balancer (DLB), and In-Memory Analytics Accelerator (IAA) is updated. The QAT driver bug is fixed. The DLB driver is upgraded. User-mode bugfixes are added in QAT and IAA. The centralized memory management solution for user-mode DMA of accelerators across architectures is added.

  • Shared Memory Communication (SMC) tools are updated. The smc-ebpf command is added to control the effective range of smc_run based on the port granularity. The control mode supports blacklists, whitelists, and intelligent scheduling.

Fixed issues

  • The following issue is fixed: If RPM packages such as kernel-modules-extra and kernel-modules-internal are not automatically installed when the kernel is updated, the netfilter-related features are unavailable.

  • The following issue is fixed: The /proc/sys/kernel/sched_group_identity_enabled interface sometimes fails to shut down because the group identity reference count is incorrect during cgroup creation or deletion.

Image updates

  • Container images

    • alibaba-cloud-linux-3-registry.cn-hangzhou.cr.aliyuncs.com/alinux3/alinux3:3.9

    • alibaba-cloud-linux-3-registry.cn-hangzhou.cr.aliyuncs.com/alinux3/alinux3:latest

      Note

      After a new version is released, you can no longer specify the latest parameter to obtain version 3.9 of images.

  • VM images

    • By default, the rpmdb format is switched to the sqlite format.

    • By default, the KeenTune service is installed and disabled.

    • By default, the NFS-server service is disabled.

Known issues

  • The kdump service may fail to work as expected on ecs.g6r.large instances due to the memory size. You can adjust the crash parameters such as 0M-2G:0M,2G-128G:256M, and 128G-:384M to prevent the kdump service failure.

  • In Network File System Version 3 (NFSv3) file systems, the S permission can be added to files. In special cases, after the owner of a file is changed, the S permission of the belonging group is missing.

    The fix for this issue is 2d8ae8c417 ("db nfsd: use vfs setgid helper"). However, the code of the auxiliary function and kernel version 5.10 required for the fix have changed greatly. This issue is not fixed.

  • After you replace TCP with SMC, the netperf test may exit unexpectedly.

    SMC uses a fixed-size ring buffer, and the remaining space in the ring buffer may be less than the amount of data specified by send() during the sending process. In this case, SMC returns the number of bytes that can be sent, which is generally less than the user-specified amount in send(). This behavior is considered abnormal and the netperf test exits. The upstream maintainers recommend maintaining the existing design to prevent the connection stalled issue. This issue is not fixed.

Important updates

  • Kernel updates

    • Community tracking

      • Devlink supports subfunction management.

        A subfunction is a lightweight function that is deployed on a parent Peripheral Component Interconnect (PCI) function. Compared with a PCI Express (PCIe) Virtual Function (VF), a subfunction is more lightweight and shares resources with its parent PCI function. A subfunction provides all networking-related resources, such as transmit queues, receive queues, and completion queues. A subfunction serves as a complete network interface controller (NIC) in Linux. This update allows you to use devlink to manage subfunctions on NICs. You can use devlink together with drivers to create, destroy, or query subfunctions on NICs.

      • IO_uring Non-Volatile Memory Express (NVMe) passthrough is supported.

        In access to storage devices, the overheads of a complex storage stack have a significant impact on latency and IOPS. As storage devices become faster, the proportion of overheads that are introduced by the software stack increases. When you access NVMe disks, you must traverse through multiple abstraction layers, including file system, block layer, and NVMe driver. This update backports the io_uring uring_cmd feature, which was introduced in mainline Linux kernel 5.19. The feature passes the actual file operations to the kernel by using io_uring. This way, the operations are not parsed at the io_uring layer and are sent directly to the NVMe driver layer, bypassing the file system layer and block layer. Additionally, to support this feature, io_uring is introduced to support CQE32 and NVMe character device creation.

      • Fine-grained permissions control is supported for NVMe and Small Computer System Interface (SCSI) persistent reservations.

        Before the update, performing persistent reservations required the CAP_SYS_ADMIN permission, which prevented the use of persistent reservations in specific non-privileged scenarios, such as containers. After the update, persistent reservations can be performed by non-privileged processes that have write permissions on block storage devices but do not have the CAP_SYS_ADMIN permission. This allows persistent reservations to be used in more scenarios.

      • The IOPS throttling of large I/O block sizes is optimized.

        In Linux kernel 5.10, IOPS throttling may not work as expected in scenarios that involve large I/O block sizes such as 1 MB. This is primarily due to the mishandling of split large I/O block sizes initiated by IOPS throttling of block throttle. This phenomenon is more apparent in I/O buffering scenarios where buffers are first stored in page caches and then written back. In these scenarios, large I/O block sizes are often generated. This issue is optimized in mainline kernel 5.18. This update optimizes the IOPS throttling of large I/O block sizes by using backported patches from the mainline kernel and fixes the vulnerability of repeatedly calculating bits per second (BPS).

      • Hash BPF maps are backported from the community for the lookup_and_delete_elem operation, and bloom filter maps are supported.

        • Before the update, the lookup_and_delete_elem operation supports only queue and stack maps. After the update, hash maps are also supported.

        • Bloom filter maps are supported to help you efficiently find sets.

      • The CPU and memory hot-swapping feature for QEMU Arm 64 that is used as the VM guest operating system.

        • The vCPU quantity can be hot-updated in the guest OS by running the virsh setvcpus command.

        • By default, the CONFIG_MEMORY_HOTPLUG_DEFAULT_ONLINE configuration is enabled to prevent the memhp_default_online_type configuration from being set to offline. This way, hot-plugged memory is automatically available for use, eliminating hot-plugging failures caused by insufficient memory that results from creating page descriptors.

      • The Hardware P-State (HWP) IO boost feature is supported for all Intel chips.

        The HWP IO boost technology enhances I/O performance. In the previous kernel versions, HWP IO boost was enabled only for specific Skylake platforms and enterprise servers. This patch removes the CPU type check to enable HWP IO boost for all CPUs by default.

      • The HugeTLB Vmemmap Optimization (HVO) feature is backported from the community.

        The HVO technique reduces the vmemmap space occupied by large pages. Specifically, this technique maps all virtual addresses of a struct page for a large page in vmemmap to the same physical address to release the physical memory occupied by the struct page.

      • The memcg Least Recently Used (LRU) lock feature is backported.

        In scenarios that require a global LRU lock, this feature replaces the global LRU lock with locks that are specific to the memcg where the involved pages reside. These scenarios include page movement, memcg movement, and swap-in and swap-out scenarios. This update reduces contention caused by the global LRU lock and improves performance by 50% in scenarios where multiple memcgs are involved.

      • Linux kernels can run on Intel TDX guests.

        Linux kernels can run on Intel TDX guests to provide various features, such as memory encryption, memory integrity protection, CPU register protection, and remote attestation of the trusted environment.

      • Performance Monitoring Unit (PMU) capabilities are enabled on Emerald Rapids (EMR) platforms.

        • EMR CPU IDs are added to PMU drivers to enable PMU capabilities on EMR platforms.

        • The Array Built-in-Self-Test (BIST) support is added to In Field Scan (IFS). IFS is a feature that runs circuit-level tests on each CPU core to detect issues that are not caught by error correction code (ECC) checks.

    • In-house features

      • Shared Memory Communication over RDMA (SMC-R) can help TCP network applications transparently use Remote Direct Memory Access (RDMA) to obtain network communication services with high bandwidth and low latency.

        SMC is a high-performance kernel network stack that is contributed by IBM to the upstream Linux. SMC-R can help TCP network applications transparently use RDMA to obtain network communication services with high bandwidth and low latency. ANCK fixes a large number of stability issues based on the upstream foundation, supports the default use of SMCv2 and SMCv2.1 protocol negotiation, and incorporates features such as max_link, max_conn, and Alibaba Vendor ID. It optimizes the number of link connections, supports Receive Queue (RQ) throttling, and supports the RDMA Write With Immediate operation. ANCK has added various diagnostic information, supports the use of the SMC protocol stack by using the PF_INET protocol family, and supports transparent replacement by using BPF.

      • The cache consistency in FUSE is enhanced, and a data collection interface is added.

        • A debugging interface is added to sysfs to display all requests that are sent to the userspace daemon and wait to be processed in a specific FUSE file system.

        • A data collection interface is added to sysfs to count and display the number and processing time of various requests for a specific FUSE file system.

        • Cache consistency in cache (cache=always|auto) mode is enhanced to apply to distributed file system backends that rely on strong consistency, such as NFS.

          1. A userspace daemon can notify the FUSE client to invalidate all directory entries (dentries) within a directory.

          2. The Close-To-Open (CTO) cache consistency model is implemented. The model implements flush-on-close and invalidate-on-open semantics on both data and metadata.

          3. The cache consistency model is enhanced in FUSE failover mode.

      • TAR files can be directly mounted in EROFS, and non-compressed 4k-block EROFS images can be mounted on the Arm 64-bit architecture that uses 16K or 64K pages.

        • Non-compressed 4k-block EROFS images can be mounted on the Arm 64-bit architecture that uses 16K or 64K pages.

        • TAR files can be used as data sources. You can use EROFS metadata to mount and access the data in the TAR files.

      • Cross-namespace propagation of FUSE mount points is supported.

        FUSE mount points can be propagated from non-privileged sidecar containers to application containers, providing a solution for FUSE-based remote storage in cloud-native scenarios.

      • Memory bloat issues that are caused by THP are fixed.

        THP enhances performance but may lead to memory bloat issues. Memory bloat can trigger out of memory (OOM) errors. For example, if an application that requests 8 KiB of memory (two 4-KiB pages) is assigned a THP, the THP consists of two 4-KiB pages that the application requests and 510 4-KiB pages that are filled with zeros, known as zero pages. As a result, OOM errors may occur due to the increase of Resident Set Size (RSS) memory usage.

        THP zero subpages reclaim (ZSR) is proposed to fix memory bloat issues. THP ZSR is a mechanism that splits THPs into subpages and reclaims zero subpages to prevent OOM errors that are caused by memory bloat.

  • System configuration updates

    • The value of tcp_max_tw_buckets is reset to 5000.

    • The default character set for mounting VFAT file systems is reset to ISO-8859-1.

  • Software package feature updates

    • By default, aliyun_cli is integrated.

    • By default, container-selinux is integrated.

    • The anolis-epao-release package is added. Alibaba Cloud Linux 3 can access packages from the Anolis OS epao repository to install AI and other applications.

Fixed issues

  • The issue that rngd.service failed to start in Alibaba Cloud Linux 3 64-bit for Arm images is fixed.

  • The bugfix is backported from the mainline kernel to address a memory leak issue that arises in a cgroup when a process fails to fork.

  • An overlayfs permission issue is fixed. If all upper directories and lower directories are located in the same file system and files or directories on which the read permissions are not granted in the file system are accessed, ovl_override_creds() cannot be executed as expected due to logic errors from previous overlayfs performance optimizations. The actual execute permissions are not elevated to the credential of the mounter, and a permission lack error is reported when read permissions are required to perform copy up operations.

  • FUSE bugfixes are backported from the mainline kernel, improving FUSE stability.

  • Multiple ext4 bugfixes of the bigalloc feature are backported from the kernel community, significantly optimizing real-time scale-outs in these scenarios.

  • Potential data consistency issues that arise when CONT-PTE or CONT-PMD is backported from the kernel community are fixed.

  • The issue that specific AMD instances cannot use resctrl is fixed.

  • The stability issue of the IAX hardware compression and decompression accelerator is fixed.

  • The cyclic redundancy check (CRC) failure in the IAX hardware compression and decompression accelerator is fixed.

  • Memory thrashing issues that are caused by the improper use of the swap_info_struct lock in high-concurrency swapon and swapoff scenarios are fixed. This bugfix is integrated into the kernel community.

  • The issue that the self-developed zombie memcg reaper feature does not take effect in one-shot mode is fixed.

  • Potential stability issues that occur on YiTian 710 instances when Memory System Resource Partitioning and Monitoring (MPAM) is used are fixed.

    The multi-pcp feature reserves memory pages that have orders greater than 0 in per-core memory pools. This eliminates the need to allocate high-order memory pages by using the zone buddy system. This also bypasses the lock of the buddy system and improves packet reception performance.

  • The IAA driver is supported to enhance compression and decompression performance.

    IAA is a hardware accelerator that provides primitive analytic features and high-throughput compression and decompression capabilities. The driver code comes from Intel code repositories and is optimized to ensure compatibility with the ANCK kernel. Bugs are fixed.

  • Silent data corruption that is caused by truncated page cache is fixed for the shmem and hugetlb file systems.

    Before the update, poisoned shmem and hugetlb pages are removed from the page cache. Subsequent access to the offset in the file results in a new zero-filled page, which causes silent data corruption. After the update, silent data corruption that is caused by poisoned pages is fixed in the shmem, tmpfs, and hugetlb file systems.

  • The CoreSight Embedded Trace Extension (ETE) driver is added, and tools under tools/perf are supported.

  • The signal handling mechanism of the Kernel-based Virtual Machine (KVM) module for the Arm 64-bit architecture is enhanced to fix failures that occur in RAS scenarios.

    Before the update, if the TIF_NOTIFY_RESUME flag is not handled before the CPU enters the guest mode, failures occur due to exceptions that are triggered by frequent RAS events. To address this issue, the full generic entry infrastructure is supported on the Arm 64-bit architecture to handle pending tasks.

  • The Coherent Mesh Network (CMN) and Direct Rendering Manager (DRM) drivers of the Linux community and debugfs are supported, and vulnerabilities are fixed.

    In versions earlier than 5.10-014, the CMN and DRW drivers deviate from those of the Linux community. To reduce maintenance costs, 5.10-014 synchronizes the CMN and DRW drivers of the Linux community and ensures compatibility with CMN-700 of YiTian 710. debugfs is supported, and vulnerabilities are fixed. The topology of CMN can be viewed in user mode.

  • Machine Check Exception (MCE) errors that are triggered by copy-on-write (COW) can be fixed on x86 instances that run in kernel mode.

    If uncorrectable errors are triggered when COW is implemented in the kernel, the system fails because it does not have recovery programs for this case where poison is consumed by the kernel. This feature adds support for recovery programs by sending a SIGBUS to applications to prevent system failures.

  • Top-down performance analysis can be performed by using performance metrics to make CPU PMU easier to use.

    In versions earlier than 5.10-014, the performance metric feature is not supported and no top-down performance analysis tool is available. In 5.10-014, the performance metric feature is supported to make CPU PMU easier to use and help users troubleshoot CPU performance bottlenecks. Top-down metrics of YiTian 710, Kunpeng, and x86 are also supported.

  • UDP Segmentation Offload (USO) is supported for virtio-net.

    Compared with UDP Fragmentation Offload (UFO), USO improves packet reception performance in complex network environments and the forwarding performance of forwarding components. Starting from version 5.10-014, USO is supported for virtio-net. Compared with UFO, USO reduces packet loss that is caused by fragment reassembly in unstable network conditions, incast scenarios, and traffic spikes. USO also reduces the overhead of fragment reassembly on the receiving side. Packet loss and out-of-order (OOO) packets cause fragment reassembly for forwarding components. As such, USO improves the efficiency of forwarding components.

  • Secure Encrypted Virtualization (SEV) and Secure Encrypted Virtualization-Encrypted State (SEV-ES) are supported. This ensures that the pre-attestation feature of SEV confidential containers works as expected.

  • The following issue is fixed: The empty pci_iounmap() implementation of the AArch64 architecture exhausts virtual address space.

    In versions earlier than 5.10-014, the pci_iounmap function is empty when CONFIG_GENERIC_IOMAP is not configured. Mapped memory cannot be released. Consequently, virtual address space is exhausted. In 5.10-014, pci_iounmap() can be implemented.

  • The high-performance ublk framework is supported.

    ublk is a high-performance framework that is used to implement block device logic from userspace based on the io_uring passthrough mechanism. ublk can be used to efficiently deploy agents in distributed storage.

  • The following technologies developed by Alibaba Cloud are supported:

    • Code block lock is supported. The code blocks that reside in memory can be locked as a whole or by cgroup.

      Low memory usage triggers memory reclamation. Code blocks of core business that are stored in the memory may also be reclaimed. When the business programs are rerun, the code blocks are retrieved from disks and then stored in the memory. Frequent I/O operations slow down response speeds and cause performance jitters. The feature locks the cgroups of the memory where core code blocks are stored to prevent the memory from being frequently swapped in and out. This feature also allows you to configure a memory lock quota. The quota specifies the proportion of code block memory that you want to retain.

    • A size limit can be specified for the page cache to free up memory space to support business growth.

      In scenarios that involve containers, the available memory that is provided by the containers is limited. If the page cache occupies a large amount of memory, memory reclamation is triggered. If the reclamation cannot meet the memory requirements for business growth, OOM errors may occur and degrade performance. To address this issue, this feature is provided by ANCK to limit the size of page cache for containers. Excess page cache is reclaimed in advance to free up memory space. This feature can limit the page cache size for all containers or containers that reside in each cgroup. This feature also supports synchronous and asynchronous reclamation methods to provide high flexibility.

    • Dynamic CPU isolation is supported.

      CPU isolation involves assigning different CPU cores or CPU sets to different tasks to prevent resource competition and improve system performance and stability. To support crucial tasks, the CPU isolation technology assigns isolated CPUs to crucial tasks and non-isolated CPUs to non-crucial tasks. The number of crucial tasks changes during task runtime. If you isolate a large number of CPUs to support crucial tasks, resources may be wasted and costs may increase. Dynamic CPU isolation allows the number of isolated CPUs to be changed to maximize resource utilization, reduce costs, and improve business performance.

    • CPU burst and the minimum memory watermark QoS capability are supported in cgroup v2.

      To promote the use of cgroup v2, the interfaces of cgroup v2 of various in-house ANCK technologies, including CPU burst and the minimum memory watermark QoS capability, are supported.

    • The vmalloc() function is supported for the XDP socket feature to allocate virtual memory to queues. This prevents XDP socket allocation failures that are caused by memory fragmentation.

      By default, the XDP socket feature uses the __get_free_pages() function to allocate contiguous physical memory. If severe memory fragmentation occurs on instances, XDP sockets may fail to be created. This feature uses the vmalloc() function to allocate memory to reduce the risks of XDP socket creation failure.

  • The boot mode is changed to UEFI, and only the UEFI mode is supported.

aliyun_3_x64_20G_alibase_20230110.vhd

2023-01-10

  • The Alibaba Cloud Linux 3.2104 LTS 64-bit base image is updated to include the latest software versions.

  • The configurations of the Plus debug repository are added.

  • Kernel updates:

    • The kernel version is updated to 5.10.134-13.al8.x86_64.

    • Kernel bugs and critical CVEs are fixed.

    • /dev/ioasid is supported.

      In versions earlier than ANCK 5.10-013, device-passthrough frameworks such as VFIO and vDPA create their own logic to isolate untrusted device DMAs that are initiated by userspace. In ANCK 5.10-013 and later, /dev/ioasid provides a unified interface to manage I/O page tables for devices that are assigned to userspace. This simplifies Virtual Function I/O (VFIO) and vDPA.

    • The performance of the SoftWare Input/Output Translation Lookaside Buffer (SWIOTLB) mechanism is optimized.

      In versions earlier than ANCK 5.10-013, the SWIOTLB mechanism that is used to communicate with peripherals uses only one lock when allocating memory. In ANCK 5.10-013 and later, the lock is split into multiple locks and allows user configuration. Confidential VMs (AMD SEV- or Intel TDX-based VMs) that have high configurations, such as more than 32 CPUs, can benefit from the change. For Redis and MySQL, the tests show that I/O performance can be improved by up to eight times after the lock splitting.

    • napi.tx is enabled in virtio-net to improve the performance of TCP Small Queue (TSQ).

      In 3bedc5bca69d ('ck: Revert "virtio_net: enable napi_tx by default"'), high si leads to performance degradations in some special scenarios. This causes TSQ not to work as expected. To fix the issue, the napi.tx feature is re-enabled.

    • The AST2600 PCIe 2D Video Graphics Array (VGA) driver is supported.

      In versions earlier than ANCK 5.10-013, ASPEED AST2600 graphics cards are not supported. In ANCK 5.10-013 and later, ASPEED AST2600 graphics cards are supported. When such a graphics card is connected to an external monitor, images can be properly displayed on the screen.

    • A switch is added for the group identity feature.

      In ANCK 5.10-013, the global sysctl switch is added for the group identity feature. By default, the switch is turned off to reduce the scheduling overhead of common processes. You can run the echo 1 > /proc/sys/kernel/sched_group_identity_enabled command to turn on the switch.

    • The default kernel boot cmdline is adjusted on the Arm 64-bit architecture.

      In 5.10.134-013 and later, the following parameter settings are added to the kernel boot cmdline on the Arm 64-bit architecture to improve performance:

      cgroup.memory=nokmem iommu.passthrough=1 iommu.strict=0
      • cgroup.memory=nokmem: disables kernel memory accounting. When enabled, kernel memory accounting results in additional logic for allocating and releasing slab pages and affects performance. For more information, visit OpenAnolis.

      • iommu.passthrough=1: bypasses the Input-Output Memory Management Unit (IOMMU) for direct memory access (DMA). This can reduce translations for page table mappings. If iommu.passthrough=1 is not added to the kernel boot cmdline, the value of CONFIG_IOMMU_DEFAULT_PASSTHROUGH is used. The iommu.passthrough parameter takes effect for physical machines.

      • iommu.strict=0: invalidates translation look-aside buffers (TLBs) in lazy mode. The lazy mode defers the invalidation of hardware TLBs during DMA unmap operations to increase throughput and the unmapping speed. If the lazy mode is not supported by the relevant IOMMU driver, the mode automatically switches back to the strict mode (iommu.strict=1). The strict mode invalidates IOMMU hardware TLBs during DMA unmap operations.

    • The Compact NUMA aware (CNA) spinlock feature is supported.

      In 5.10.134-013 and later, NUMA awareness is added to qspinlock. One of the following kernel boot cmdline parameter settings can be added to enable the CNA spinlock feature: numa_spinlock=on or numa_spinlock=auto.

      After this feature is enabled, qspinlock can give a lock to the CPU of the same NUMA node as much as possible when CPUs on different NUMA nodes compete for the spinlock. This reduces the number of cross-NUMA sessions and improves performance. In the benchmark tests of sysbench and leveldb, performance is improved by more than 10%.

    • The perf mem and perf c2c commands provide more features on the Arm 64-bit architecture.

      In 5.10.134-013 and later, the perf mem and perf c2c commands are extended to provide more features. On the Arm 64-bit architecture, perf mem and perf c2c can be used to show the data sources of samples, such as L1 hit. perf mem supports synthesized memory events, synthesized instruction events, synthesis directive events, and instruction delay information. perf c2c provides the capability of locating NUMA node information.

    • fsck.xfs supports journal replay.

      After a machine breaks down, file systems may be in the inconsistent state and the journal log is not replayed. In xfsprogs-5.0.0-10.0.4 and earlier, this may drop the machine into the rescue shell because fsck.xfs does not support journal replay, which brings maintenance trouble. In xfsprogs-5.0.0-10.0.5 and later, fsck.xfs supports journal replay. When you assume the administrator role, you can set the fsck.mode parameter to force and the fsck.repair parameter to yes to enable journal replay. Take note that journal replay takes effect only for system disks.

    • Adaptive Huge Pages are supported.

      In 5.10.134-013 and later, the adaptive Huge Pages feature is provided to resolve hardware drawbacks, especially for x86 platforms. An example of the hardware drawbacks is that Intel Skylake has only eight iTLB entries to use. This feature selects the most popular 2 MB areas into huge pages based on page table entry (PTE) scan results. In short, this feature provides two system interfaces to limit the number of huge pages per application and prevent performance degradations that are caused by iTLB miss increase. This feature is applicable to Java applications and applications with large code segments, such as ApsaraDB for OceanBase and MySQL.

    • Software Guard Extensions (SGX) dynamic memory management is supported.

      In versions earlier than ANCK 5.10, the dynamic management of SGX enclave memory is not supported. In ANCK 5.10 and later, the SGX Enclave Dynamic Memory Management (EDMM) feature is provided to allow the dynamic management of SGX memory.

    • The WireGuard module is enabled.

      In versions earlier than ANCK 5.10-013, the WireGuard module is disabled. In ANCK 5.10 and later, the WireGuard module is enabled. WireGuard is an easy-to-configure, fast, and secure virtual private network (VPN) that can replace IPSec. WireGuard is abstract and suitable for general use in most scenarios.

      • The XFS 16k atomic write feature is supported. Compared with double writes, XFS 16k atomic writes improve the performance of disks by up to 50% and reduce I/O on disks. The corresponding xfsprogs and mariadb repositories are updated to Anolis YUM repositories. This solution has the following advantages over the hardware-based atomic write solution:

        • This solution is based on the COW technique.

        • This solution does not depend on hardware.

        • This solution does not depend on runtime I/O path configurations.

        The XFS 16k atomic write feature can be used together with the Hugetext feature. For more information, see Work with MariaDB 16K atomic writes.
