behzad nouri 161838655c removes port-based forwarding logic from turbine retransmit (#17716) ... Turbine retransmit logic is based on which socket it received the packet from (i.e `packet.meta.forward`): https://github.com/solana-labs/solana/blob/708bbcb00/core/src/retransmit_stage.rs#L467-L470 This can leave the cluster vulnerable to spoofing and selective propagation of packets; see https://github.com/solana-labs/solana/issues/6672 https://github.com/solana-labs/solana/pull/7774 This commit identifies if the node is on the "critical path" based on its index in the shuffled cluster. If so, it forwards the packet to both neighbors and children; otherwise, the packet is only forwarded to the children. The metrics added in https://github.com/solana-labs/solana/pull/17351 shows that the number of times the index does not match the port is very rare, and therefore this change should be safe.		2021-06-15 13:19:41 +00:00
