I just tried to checkpoint a Go program with a simple HTTP server compiled with 1.24 and ran into this error:

(00.026522) Error (criu/sk-inet.c:130): inet: Unsupported proto 262 for socket 2f9bc5

Looks like MPTCP is now enabled by default for all Go TCP sockets so it would be great if criu would be able to checkpoint/restore these.
