From mboxrd@z Thu Jan 1 00:00:00 1970 Content-Type: multipart/mixed; boundary="===============5170112647898363106==" MIME-Version: 1.0 From: Paolo Abeni To: mptcp at lists.01.org Subject: [MPTCP] [PATCH v3 00/13] mptcp: support for queuing data at mptcp-level Date: Fri, 02 Oct 2020 11:26:10 +0200 Message-ID: X-Status: X-Keywords: X-UID: 6151 --===============5170112647898363106== Content-Type: text/plain; charset="utf-8" MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable This is necessary to cope correctly with large sendbuffer (larger then snd = wnd) while respecting the MPTCP level snd window. A major rework of both xmit and shudown path is required to support this feature (patches 8 and 9). To try to keep the related patches as small as possible, a bunch of new helpers is created by patches 3-7. Note that patch 5 can stand for it's own merit and possibly be upstreamed s= oon. Finally patch 10 uses the MPTCP equivalent of tcp_push_pending_frames(), to spool queued data ad MPTCP level, as soon as the windows allow that. Patches 1 and 2 are bugfixes for the current upstream tree will target -net/-net-next soon. Patch 13 is possibly a bit too aggressive, perhaps it could be left staging in export branch for a while. This iteration fixes all known pending issue present in previous snapshow. Note that we still hit some unexpected out of receive window events, but the issue was already present in the export branch and its fix is unrelated to this work.
