From mboxrd@z Thu Jan 1 00:00:00 1970 Content-Type: multipart/mixed; boundary="===============6505138484021689441==" MIME-Version: 1.0 From: Mat Martineau To: mptcp at lists.01.org Subject: [MPTCP] [PATCH net-next v4 00/11] Date: Thu, 19 Dec 2019 14:05:46 -0800 Message-ID: <20191219220557.17823-1-mathew.j.martineau@linux.intel.com> X-Status: X-Keywords: X-UID: 3185 --===============6505138484021689441== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable v3 -> v4: Update coalesce/collapse of incoming MPTCP skbs (patch 7) v2 -> v3: Ensure sk_type alignment in struct sock (patch 2) v1 -> v2: sk_pacing_shift left as a regular struct member (patch 2), and modified SACK space check based on recent -net fix (patch 9). 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.
