2 years ago Hello,
Ubuntu 22.04 comes with a newer kernel containing a re-implementation of MPTCP. This implementation had to be different to be accepted in the vanilla/upstream kernel. Some features are still missing, the work is in progress. You can follow the development there: https://github.com/multipath-tcp/mptcp_net-next
Please check this wiki page to know the different between the "out-of-tree" kernel (this project) and the upstream one (the one coming with Ubuntu 22.04): https://github.com/multipath-tcp/mptcp_net-next/wiki#upstream-vs-out-of-tree-implementations=
You can still install an older kernel and get the out-of-tree implementation but best is probably to check if the upstream one suite you, open ticket/send patch if not and if it is really blocking, switch to the out-of-tree kernel.
I hope you don't mind if I close this ticket as the "issue" is not with this kernel.
Hello there,
first of all, thank you o much for the great protocol.
I have installed mptcp in Ubuntu 22 and, sysctl net.mptcp.enabled is returning 1, but I can not see mptcp in uname -a, and in the net/mptcp folder threre are only five files. What can be wrong? Would you please help me.
Thanks a lo
