Message

Mat Martineau Nov. 3, 2020, 7:05 p.m. UTC

This is a collection of small fixup and minor enhancement patches that
have accumulated in the MPTCP tree while net-next was closed. These are
prerequisites for larger changes we have queued up.

Patch 1 refines receive buffer autotuning.

Patches 2 and 4 are some minor locking and refactoring changes.

Patch 3 improves GRO and RX coalescing with MPTCP skbs.

Patches 5-7 add a sysctl for tuning ADD_ADDR retransmission timeout,
corresponding test code, and documentation.


v2: Add sysctl documentation and fix signoff tags.


Florian Westphal (3):
  mptcp: adjust mptcp receive buffer limit if subflow has larger one
  mptcp: use _fast lock version in __mptcp_move_skbs
  mptcp: split mptcp_clean_una function

Geliang Tang (2):
  mptcp: add a new sysctl add_addr_timeout
  selftests: mptcp: add ADD_ADDR timeout test case

Mat Martineau (1):
  docs: networking: mptcp: Add MPTCP sysctl entries

Paolo Abeni (1):
  tcp: propagate MPTCP skb extensions on xmit splits
