Subject: [PATCH net-next v2 00/15] mptcp: ADD_ADDR enhancements
Date: Mon, 1 Feb 2021 15:09:05 -0800 [thread overview]
Message-ID: <20210201230920.66027-1-mathew.j.martineau@linux.intel.com> (raw)
This patch series from the MPTCP tree contains enhancements and
associated tests for the ADD_ADDR ("add address") MPTCP option. This
option allows already-connected MPTCP peers to share additional IP
addresses with each other, which can then be used to create additional
subflows within those MPTCP connections.
Patches 1 & 2 remove duplicated data in the per-connection path manager
structure.
Patches 3-6 initiate additional subflows when an address is added using
the netlink path manager interface and improve ADD_ADDR signaling
reliability, subject to configured limits. Self tests are also updated.
Patches 7-15 add new support for optional port numbers in ADD_ADDR. This
includes creating an additional in-kernel TCP listening socket for the
requested port number, validating the port number when processing
incoming subflow connections, including the port number in netlink
interfaces, and adding some new MIBs. New self test cases are added for
subflows connecting with alternate port numbers.
v2: Address review comments for patch 1 (drop unnecessary READ_ONCE()
under lock). Drop patch 16, which will be submitted later.
Geliang Tang (15):
mptcp: use WRITE_ONCE for the pernet *_max
mptcp: drop *_max fields in mptcp_pm_data
mptcp: create subflow or signal addr for newly added address
mptcp: send ack for every add_addr
selftests: mptcp: use minus values for removing address numbers
selftests: mptcp: add testcases for newly added addresses
mptcp: create the listening socket for new port
mptcp: drop unused skb in subflow_token_join_request
mptcp: add a new helper subflow_req_create_thmac
mptcp: add port number check for MP_JOIN
mptcp: enable use_port when invoke addresses_equal
mptcp: deal with MPTCP_PM_ADDR_ATTR_PORT in PM netlink
selftests: mptcp: add port argument for pm_nl_ctl
mptcp: add the mibs for ADD_ADDR with port
selftests: mptcp: add testcases for ADD_ADDR with port
