Subject: [MPTCP] [RFC PATCH 0/4] mptcp: [try to] fix armegaddon on late tcp fallback
Date: Fri, 13 Dec 2019 15:33:48 +0100 [thread overview]
Message-ID: <cover.1576247361.git.pabeni@redhat.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 702 bytes --]
Passive connection can fallback to TCP after that the subflow is established.
That leads to disaster in several nasty ways.
Address the issue explicitly falling back to TCP (converting the socket) as
soon as we notice the unsuccessful MPC hanshake completion.
Sent as a very early RFC - completely untested yet.
Paolo Abeni (4):
mptcp: add helper to forcefully fallback the msk socket to TCP
mptcp: cache the first subflow sock
mptcp: late fallback support
mptcp: deal with fallback in additional places.
