Hello, Yesterday, we had our 72nd meeting with Mat, Peter and Ossama (Intel OTC), Paolo, Florian and Davide (RedHat) and myself (Tessares). Thanks again for this new good meeting! Here are the minutes of the meeting: Accepted patches: - mptcp: recvmsg refactor follow-up: - by Paolo - fix tests - Accepted by Matth & Mat - Fix issues in prerequisite [IPv6] patches: - by Peter - 3 patches: 1 has been applied, accepted by Matth Pending patches: - mptcp: switch mptcp_poll to use parent sock wait queue: - include: mptcp: sendmsg scheduler skeleton - include: mptcp_poll should not block on each subflow: - by Florian - v2 - Accepted by Paolo - *Waiting for application* - selftests: mptcp: increase test coverage: - include: selftests: fixes and improvements - include: prepare for mptcp ipv6 support - by Florian - v3 sent + 1 new one - *Waiting for review* - mptcp: Add DATA_FIN transmission and handling: - by Mat - RFC - Commented by Paolo, Christoph - new version expected - IPv6 support: - by Peter - RFC - Commented by Paolo, Matth - new version expected - Fix issues in prerequisite [IPv6] patches: - by Peter - 3 patches: 2 are left on review - Paolo raised a question about IPv4 mapped in IPv6: add the support for later? - new version expected - selftests:mptcp: increase timeout: - by Matth - v2 - *Waiting for review* - Fix bug processing options: - by Peter - *Waiting for review* Remaining items for the initial submission: Planning: - Part 1 (mainly TCP changes, will be sent with Part 2): - MAINTAINERS file - Part 2 (minimum set for MPTCP, up to KSelftests, one subflow): - MPTCPv1 support - opti in TCP options? - Send DATA_FIN, no corner cases - Part 3 (after the KSelftests, to be sent ideally before the end of the year) - Full DATA_FIN support - Shared recv window - Active backup support Remaining items for the initial submission: Update: - IPv6 support → part 2: - Peter is working on a v2 - MPTCP v1 support → part 2: - Paolo started to look at the RFC to support Christoph - Christoph will be the submitter of the patch - *Matth*: publish a branch with mptcp.org + MPTCPv1 - is it OK to have v0 then switch to v1 in the same series? - maybe better to do the squashing to have a clearer code (hoping the v1 simplify a bit some parts) - will check if we squash or not when we have the code - DATA_FIN → part 3 (after kselftests): - Mat is working on it - working on top of the recent changes done and the mptcp_rcvmesg refactor - trying to list the different corner cases (e.g. this is the last packet and it is dropped) - maybe we can have only the sending part for the moment without the corner cases in the part 2 (before kselftests, after TCP) - Mat will look at that perspective - Shared recv window → part 3 (after kselftests, OK because we only support one subflow before that): - work to be done - Active backup support → part 3 (after kselftests) or 4 (extra): - Paolo is working on it - receive part is done - send side is handle by Florian - found one issue with MP_JOIN - optimisation of options in TCP "struct mptcp_options_received": - Peter has a patch to share - MAINTAINERS file timeout in selftest: - we will try to have default "series" around ~45seconds IPv4 mapped in IPv6: - add the support for later - only support v4 only and v6 only Feedback from netdev: - nope :'( - could be good to send a message to the list, explaining with other words what we have sent, what it would be useful for us - it is likely possible that we will not get any replies if we don't ask or send something else - Mat was asking if it could help if someone else was sending the patches? Maybe just unlucky: reviewers were maybe busy Patchwork: - we need username - Mat will check with Peter which one to use - *Matth* will send the list to Patchwork maintainers - Mat added their email in the subscribers list Netdev?: - https://netdevconf.info/0x14/news.html?netdev-0x14-call-for-submissions - In Vancouver - close to Seattle - Submission: around January Next meeting: - We propose to have it next Thursday, the 31st of October. - *NOT* the usual time if you are going to change the clock this weekend: 16:00 UTC (9am PDT, *5pm CET*) - Still open to everyone! - https://annuel2.framapad.org/p/mptcp_upstreaming_20191031 Feel free to comment on these points and propose new ones for the next meeting!
