BPF maintainer NACKs page_owner iterator series as overkill
Alexei Starovoitov wants one thin kfunc and a bpf_for loop instead of dual iterators, string-printing helpers, and a debugfs rewrite.

BPF unwinding lets Rust and C++ keep their destructors
New unwind instructions aim to make exceptions and RAII viable in BPF just as Rust is being pushed into parsing untrusted kernel-facing protocols, trading verifier complexity for safer language runtimes.

Untrusted csum_start and offset values can no longer leave CHECKSUM_PARTIAL pointing at arbitrary packet bytes after protocol decisions have been made.

Programs compiled against kernel type information lack a stable ABI, so systemd joins ZFS and NVIDIA in linuxPackages.
By chrootLinux hardens virtio-net checksum offload against rogue metadata
After a public report, the kernel will only trust CHECKSUM_PARTIAL when offsets match real TCP or UDP headers, or complete the checksum before protocol processing.
