These two places make it sound like it's interpreter only behavior. I've reworded it like: -the interpreter context is a pointer to networking packet. ``BPF_ABS`` +the program context is a pointer to networking packet. ``BPF_ABS`` -interpreter will abort the execution of the program. +program execution will be aborted. and pushed to bpf-next with the rest of patches.
