GNU poke is a new interactive editor for binary data. Not limited to editing basic entities such as bits and bytes, it provides a full-fledged procedural, interactive programming language designed to describe data structures and to operate on them.

This talk covers the ongoing effort about adding eBPF support to the GNU Toolchain. eBPF is a virtual machine running within the Linux kernel; initially intended for user-level packet capture and filtering, eBPF has since been generalized to also serve as a general-purpose infrastructure for non-networking purposes.
