Classic BPF vs eBPF — The Linux Kernel documentation

WebOur larger BPF-related project right now is implementing BPF-based packet scheduling for MPTCP. One MPTCP connection may aggregate multiple TCP "subflows", and the packet scheduler chooses which of those subflows to use for each outgoing packet. So far we have been focusing on BPF-based TCP congestion control code as a template. WebMay 8, 2010 · Classic BPF is using BPF_MISC class to represent A = X and X = A moves. eBPF is using BPF_MOV BPF_X BPF_ALU code instead. Since there are no BPF_MISC operations in eBPF, the class 7 is used as BPF_ALU64 to mean exactly the same operations as BPF_ALU, but with 64-bit wide operands instead.
