Multipath TCP

#MPTCP in #Linux v6.4 got some improvements around the reception of connection requests:

  • Some refactoring around the reception of MPCapable/MPJoin connection requests
  • MPTCP_INFO and Netlink (ss -M) no longer fill info not used by the PM in used
  • First subflow allocation is moved at MPCapable access time

Many fixes have also been done and backported to stable versions. There was even a special mention in v6.3-rc7 announcement 😄

Nothing particular stands out in the rc this week, unless you count the mptcp selftest changes that are about making the tests work on stable kernels too. That accounts for almost a quarter of the patch…
