Ah thanks. Will have to open tcp.c, but it gets crazier every year it might take some time... It would make sense to keep it permanently if the justification is purely based on the risk of icmp spoofing. But TCP connections can be very long-lived and the network might change under your feet, even worst if you're doing some bonding/teaming or container-/connection-migration, it might be a good idea to probe the path mtu again. It's just a pain from a latency perspective. I wish I could skip a bit of a stream without re-establishing the full connection.
