Subject: [PATCH v2 mptcp-next 0/8] mptcp: refactor active backup
Date: Tue, 13 Jul 2021 23:13:30 +0200 [thread overview]
Message-ID: <cover.1626210682.git.pabeni@redhat.com> (raw)
This series addresses a bunch of issues somewhat related to active
backup handling. The most visible functial issue addressed here is:
https://github.com/multipath-tcp/mptcp_net-next/issues/191
This series also add some specific self-tests, to cover both
active-backup switch-over and proper usage of backup link.
A new netns parameter is introduced:
stale_loss_cnt - the max amount of mptcp rtx timeouts with no progresses
and outstanding data over a single subflow needed to declare
such subflow 'stale': no more data will be queue until some ack
is observed.
Changes from v1:
- stale_loss_cnt is now configurable via sysctl
- addressed buglet noted by Mat on v1
- fixed timeout update issues in patches 1-2
- fixed splat in __mptcp_clean_una() on reinection
- the new self-tests are now less unstable
Paolo Abeni (8):
mptcp: more accurate timeout
mptcp: less aggressive retransmission stragegy
mptcp: handle pending data on closed subflow
mptcp: cleanup sysctl data and helpers
mptcp: faster active backup recovery
mptcp: add mibs for stale subflows processing
mptcp: backup flag from incoming MPJ ack option
selftests: mptcp: add testcase for active-back
