Earlier implementation assumed last instruction is BPF_EXIT. Since this is no longer a restriction in eBPF, we remove this limitation. Per Alexei Starovoitov [1]: > classic BPF has a restriction that last insn is always BPF_RET. > eBPF doesn't have BPF_RET instruction and this restriction. > It has BPF_EXIT insn which can appear anywhere in the program > one or more times and it doesn't have to be last insn.
