Hi Matt,

There are several questions I didn't answer clearly in the last meeting.
Here I try to write them down:

1 My name pronunciation
Geliang Tang sounds like Glenn Town.

2 My ideal meeting time
Every hour from 11am to 6pm (my location time-zone) at every working day is
fine to me to attend the meeting.

3 What would you like to work on?
I'm interested in the BPF topic in the last meeting. But I don't have any
idea about this at the moment. Can you please give me more detail about it
and I'll spend some time to learn it.

-Geliang

Thank you, that's helpful!

I just sent another email now that I am back to work. Did you see it?
I guess you subscribed to the ML but just in case: 
https://lists.01.org/hyperkitty/list/mptcp(a)lists.01.org/thread/SHULDCJUWQJX7CWUH6N66MFTRW6TAODS/

The best would be to have a single meeting, once per week where 
everybody can join. But it would always be difficult for people of some 
time zones...
I know it is very late and not in the working hours but do you think 
having the meeting one hour sooner (11pm your time) would be OK for you? 
Maybe not every week of course. Don't be afraid to say no!

An alternative would be to organise other meetings with less people.
But sadly, I don't see other possibilities. Feel free to share if any!

At the last meeting, we discussed about BPF because a new dev asked to 
work on this subject. He is for the moment looking at having the 
possibility to set in BPF some socket options per subflow.

Maybe later, he might look at adding BPF_CGROUP_SOCKET to allow 
per-cgroup override of proto in the socket() call. More details in 
https://github.com/multipath-tcp/mptcp_net-next/issues/18

But still in BPF, it would be good to look at other stuffs like 
modifying the behaviour of the Path Manager or the Scheduler with BPF.
Some works were done in a fork of the out-of-tree kernel, maybe it can 
help: https://dial.uclouvain.be/pr/boreal/object/boreal:225610

Cheers,
Matt

11pm is fine to me. Hope it is not too early to other people.

Thank you for your reply!

Great, thank you being available that late, that will be easier with 
only one meeting! Because I didn't receive answers from everybody and 
people in the US are likely sleeping now, I propose to keep the meeting 
this evening at the same time as last week. Sorry for that, do not feel 
forced to join if it is too late for you!

If it is OK with everybody, the next meeting would be scheduled one hour 
sooner.

Cheers,
Matt
