    KernelCI joins the Linux Foundation
    A long-anticipated move has finally been made
    official    : the KernelCI
    continuous-integration project has found a new home under the Linux
    Foundation umbrella. "The primary goal of KernelCI is to use an open
    testing philosophy to improve the quality, stability and long-term
    maintenance of the Linux kernel. Expected improvements to the platform
    under the Linux Foundation include improved LTS kernel testing and
    validation; consolidation of existing testing initiatives; quality-of-life
    improvements to the current service; expanded compute resources; and
    increased pool of hardware to be tested. In the long-term, members expect
    to modernize the architecture; test software beyond the Linux kernel; and
    define testing standards and engage in cross-project collaboration.    "

    [$] Type checking for BPF tracing
    The BPF in-kernel virtual machine has
    brought a new set of capabilities to a number of functional areas in the
    kernel, including, significantly, tracing.
    Since BPF programs run in the kernel, much effort goes into ensuring that
    they will not cause problems for the running system;
    to that end, the BPF verifier checks every possible aspect of each BPF program's
    behavior to ensure that it is safe to run in the kernel — with one notable
    exception. With a patch set titled "revolutionize
    bpf tracing    ", Alexei Starovoitov aims to close that loophole and
    eliminate a set of potential problems in a widely used class of BPF
    programs.
