Multipath TCP

#MPTCP in the future #Linux v6.5 version should have more exposed info:

  • LSM/SELinux: correctly inherit labels on MPTCP subflows
  • New ADD_ADDR (+ echo) transmission MIB counters
  • New aggregated data counters exposed via Netlink and getsockopt(MPTCP_INFO)
  • New getsockopt(MPTCP_FULL_INFO) aggregating MPTCP and subflows info (with ID)
  • Some clean-up and small improvements (MPTCP and selftests + support of old kernels)

(These modifications are in Linus’ tree, hopefully everything will still be there when v6.5 will be released!)
