  • GCC Toolset 11

  • LLVM Toolset 13.0.1

  • Rust Toolset 1.58.1

  • GoToolset 1.17.7

03 Kernel

  • Fixed the use after free problem when tcp free skb, the virtio length problem, the virtio-net XDP queues problem, the Feiteng architecture acs problem, and the interruption of distribution failure.

  • bpf supports the nettrace function, which allows developers to track the cause of network packet loss through bpf (the kernel also rounds related packet loss trace points).

  • The sli active monitoring function is supported, allowing performance monitoring indicators to be set through the sli interface, and the kernel will actively notify when a performance problem is detected, thereby reducing the periodic monitoring overhead of user-mode components.

  • The cgroup thp function is supported. This function can control the thp usage status of all processes in a container, allowing users to enable thp at the container granularity.
