[PATCH mptcp-next v8 0/8] The infinite mapping support

[Geliang Tang <geliang.tang@suse.com>]

v8:
 - Patches 1-6 are unchanged, only updated the selftests scripts.
 - The patch (Squash to "mptcp: infinite mapping receiving" for v7) is
dropped too. Since this series only implemented MP_FAIL in one direction.
The TODO items, "MP_FAIL echo" and "MP_FAIL retrans", will implement later
as new patches.

v7:
 - drop the patch "mptcp: add last_ack_dss_start in the msk" in v6
 - set allow_infinite_fallback to false in __mptcp_subflow_connect and
   mptcp_finish_join.

v6:
 - use allow_infinite_fallback instead of last_retrans_seq.
 - rename mptcp_is_data_contiguous to mptcp_allow_infinite_fallback.
 - rename last_fully_acked_dss_start_seq to last_ack_dss_start.

v5:
 - move last_retrans_seq from msk to mptcp_subflow_context

v4:
 - update patch 1 and patch 2

v3:
 - drop MPTCP_INFINITE_DONE flag
 - drop MAPPING_INFINITE
 - add mptcp_is_data_contiguous helper
 - add the fallback check
 - The u32 target testcase has not been completed yet.

v2:
 - add MPTCP_INFINITE_DONE flag
 - add MAPPING_INFINITE mapping status
 - add start_seq in the msk

v1:
 - add noncontiguous flag
 - add the mibs check
 - tag: export/20210904T080009

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/216
