We just had our 22th meeting with Mat and Peter (Intel OTC), Christoph
(Apple) and myself (Tessares).
Thanks again for this new good meeting!
Here are the minutes of the meeting:
mptcp_net-next: lockless sf patch-set proposed:
- there were some confusions in the comments (see next point to
resolve this issue)
- but going to be merged and need to be tested
- now we are aligned with mptcp_trunk
big changes on mptcp-dev:
- if also for mptcp_net-next: should we involve upstream ML for the
- the decision is to at least put Mat in CC.
More cleanup in mptcp-net-next:
- removing features/optimisations → Christoph is looking at that:
the goal is to remove features to simplify the code, patch will follow.
- but these features/optimisations will continue to be maintained in
- Note in recent kernels: GSO + SG are now enabled by default
- rethinking scatter-gather support.
- @Christoph / @Mat: may you re-share your point of views about
that here please?
- it could be nice to have a nice split between MPTCP and TCP for
the send part (it then means we don't need the re-injection for the
first version, some static values, etc.)
New test suite/environment for mptcp_net-next:
- Matth is working on testing mptcp_trunk, can be nice to have
mptcp_net-next but if we remove features, that will become difficult to test
- same for Christoph's test suite
- there is packetdrill but support for MPTCP in Open-Source is not
very nice (would be amazing to have people working on that)
- we don't see any (open-source) test suites for the kernel with
MPTCP support. Feel free to share if you have new ideas!
- maybe "re-using" the old testing suite for MPTCP: KVM hosts and
doing some tests in bash
- Matth: looking at alternatives for next time
How is Google Meet:
- Works good, quality is good, no disconnection
- last alternative is Jitsy (webrtc + phone) but seems not needed
- We will then continue to use Meet
- Please ask me (Matt) to share the Google calendar invitation with you.
- same as last week.
- We propose to have it on Wednesday this time, the 26th of
September. Usual time: 9am PDT - 16:00 UTC (9am PDT, 6pm CEST)
- Still open to everyone!
Feel free to comment on these points and propose new ones for the next
Talk to you next week,
