Mat Martineau has uploaded this change for review. ( https://review.gerrithub.io/c/multipath-tcp/mptcp_net-next/+/452480 Change subject: tcp, ulp: Add clone operation to tcp_ulp_ops ...................................................................... tcp, ulp: Add clone operation to tcp_ulp_ops If ULP is used on a listening socket, icsk_ulp_ops and icsk_ulp_data are copied when the listener is cloned. Sometimes the clone is immediately deleted, which will invoke the release op on the clone and likely corrupt the listening socket's icsk_ulp_data. The clone operation is invoked immediately after the clone is copied and gives the ULP type an opportunity to set up the clone socket and its icsk_ulp_data.
