Subject: [PATCH net-next 00/11] Multipath TCP: Prerequisites
Date: Fri, 13 Dec 2019 15:00:11 -0800
Message-ID: <20191213230022.28144-1-mathew.j.martineau@linux.intel.com> (raw)

The MPTCP upstreaming community has been collaborating on an
upstreamable MPTCP implementation that complies with RFC 8684. A minimal
set of features to comply with the specification involves a sizeable set
of code changes, so David requested that we split this work in to
multiple, smaller patch sets to build up MPTCP infrastructure.

The minimal MPTCP feature set we are proposing for review in the v5.6
timeframe begins with these three parts:

Part 1 (this patch set): MPTCP prerequisites. Introduce some MPTCP
definitions, additional ULP and skb extension features, TCP option space
checking, and a few exported symbols.

Part 2: Single subflow implementation and self tests.

Part 3: Switch from MPTCP v0 (RFC 6824) to MPTCP v1 (new RFC 8684,
publication expected in the next few days).

We plan to send those over the next week. Additional patches for
multiple subflow support, path management, active backup, and other
features are in the pipeline for submission after making progress with
the above reviews.
