[PATCH mptcp-next v10 0/8] userspace pm remove id 0 subflow & address

Posted by Geliang Tang 7 months, 2 weeks ago

v10:
 - add mptcpi_subflows_total counter, instead of no_initial_subflow
   flag.
 - rename the helper to __mptcp_has_initial_subflow, add READ_ONCE() in
   it.

v9:
 - update __mptcp_check_initial_subflow().
 - split the code that relies on the 'ss' modification into patch 9.

v8:
 - merge two squash-to patches for v7.
 - address to #428 too.

v7:
 - move evts_get_info into mptcp_lib.sh, update userspace_pm.sh with
   this helper too.
 - drop the last two cleanup patches, they'll be sent in another series.

v6:
 - add a new helper get_info_value, update chk_mptcp_info(),
   verify_listener_events() and pedit_action_pkts() too.
 - only patch 1, 2, 4 are changed, other patches are the same as v5.

v5:
 - update userspace_pm_add_addr/sf helpers.
 - add userspace_pm_rm_addr/sf helpers.
 - remove id 0 subflow or address will send MP_RST, add chk_rst_nr for
   them.
 - add two selftests cleanups using for-loop.

v4:
 - add evts_get_info and chk_subflows helpers.
 - split the selftests patch into three.

v3:
 - address Matt's comments in v2.

v2:
 - fix CI errors.

This patchset addresses #379 and #391, add the abilities to remove id 0
subflow and address for userspace PM. And a selftest.
