[PATCH v3 mptcp-next 0/6] mptcp: add some more diag info
Posted by Paolo Abeni 12 months ago
This is a follow up to the topic discussed in recent pubblic mtg.

Introduces unique id for accurate subflow stats tracking and
aggregate mptcp counters, plus some minimal self-tests.

The tests themself do not take in account support for running on
older kernel.

This is on top of "mptcp: a bunch of data race fixes".

There should be non trivial conflicts with:

"mptcp: use get_retrans wrapper".

v2 -> v3:
 - address Matttbe comments on patch 1, 2 and 5, see the indivdual
   patches changelog for the details

v1 -> v2:
 - introduce MPTCP_FULL_INFO instead of overloading a tcp_info field
 - add related self-tests
 - fix a couple of subflow_id initialization bugs

Paolo Abeni (6):
  mptcp: add subflow unique id
  mptcp: introduce MPTCP_FULL_INFO getsockopt
  mptcp: move snd_una update earlier for fallback socket.
  mptcp: track some aggregate data counters.
  selftests: mptcp: explicitly tests aggregate counters
  selftests: mptcp: add MPTCP_FULL_INFO testcase
