[PATCH mptcp-next v9 0/4] setsockopt per subflow: BPF

[Geliang Tang <geliang@kernel.org>]

From: Geliang Tang <tanggeliang@kylinos.cn>

v9:
 - validate the return value of snprintf in patch 2 as Mat suggested.
 - patch 2 depends on "selftests/bpf: Add RUN_MPTCP_TEST macro", so this
   series could be merged in this order:
   1 selftests/bpf: Add mptcp subflow example
   2 selftests/bpf: Add RUN_MPTCP_TEST macro
   3 selftests/bpf: Add mptcp subflow subtest
   4 selftests/bpf: Handle SIGINT when creating netns

v8:
 - update the git metadata to add Nicolas as the git "Author" and add a
   "Co-authored-by" tag with my name in patch 1 as Mat suggested in v7.
 - use send_byte in patch 2 instead of send_recv_data, to make this
   series independent of the commit "selftests/bpf: Export send_recv_data
   helper", which is in bpf-next, but not in mptcp_net-next at this moment.

v7:
 - address Mat's comments in v6 (thanks): drop MPTCP_BASE_TEST and rebased.
 - depends on:
 "refactor mptcp bpf tests" v7
 "export send_byte and send_recv_data" v2

v6:
 - Deponds on "[bpf-next] export send_byte and send_recv_data" series.

v5:
 - #1-#7 Address #76: add new macros MPTCP_BASE_TEST and RUN_MPTCP_TEST.
 - #8-#14 add MPTCP_SCHED_TEST macro.

v4:
 - #1-#5 Address #76: add a new macro RUN_MPTCP_TEST.
 - #6-#11 Cleanups: add send_data_and_verify and SCHED_TEST.

v3:
 - deal with EAGAIN.
 - add _ss_search helper.

v2:
 - fix checkpatch warnings.
 - cleanups.
