Good point, Paolo was certainly right, as always :) We do need to investigate. Note that it might be hard for me to do that the next few days as I'm travelling for work, but we are tracking the issue: https://github.com/multipath-tcp/mptcp_net-next/issues/574 I see that you already marked the mptcp-connect-sh selftest as ignored, so I guess we are not causing other troubles with the CI. (We could then also apply this series here and ignore the new tests, but it is also fine for me to wait.) Cheers, Matt -- Sponsored by the NGI0 Core fund.
