eBPF BoF
summary
Gathering of eBPF users and developers maps current pain points: community resources like docs.ebpf.io and meetups are growing, but kernel verifier bugs still cause crashes and deadlocks and bounded loops are only recently allowed. Proposal surfaces to refactor the verifier into a loadable kernel module or run a user-space verifier to speed testing and backport features to older kernels. Debug-info/DWARF size and missing inline/local-variable support push work toward extending BTF and compiler cooperation to enable reliable tracing.
