• [$] KASAN for JIT-compiled BPF code

    From LWN.net@618:250/24 to All on Wed Jun 24 06:40:09 2026


    Alexis Lothoré has been working to add support for the kernel's memory-access checker,

    KASAN, to just-in-time-compiled BPF code. He spoke about that work at
    the 2026

    Linux Storage, Filesystem, Memory-Management, and BPF Summit.
    KASAN support is needed, he said, to help catch bugs in the BPF just-in-time (JIT)
    compiler. KASAN is a great tool for catching memory-management problems in the kernel, but only in code that can be monitored by it.
