[mptcp-next,v2,0/4] BPF 'force to MPTCP'

Message

Geliang Tang July 1, 2023, 12:56 p.m. UTC

v2:
 - Address issue #79 "allow 'force to MPTCP' mode: BPF".
 - Define the prog in patch 3 in SEC "cgroup/sock_create" instead of
  "sockops".
 - Update other patches correspondingly.

v1:

This series depends on the two netns patches, should be inserted before
the BPF scheduler series:
  selftests/bpf: use random netns name for mptcp
  selftests/bpf: add two mptcp netns helpers
  bpf: Add bpf_mptcpify helper
  selftests/bpf: Test bpf_mptcpify helper
  selftests/bpf: Add mptcpify selftest
  mptcp: refactor push_pending logic

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/79

Geliang Tang (4):
  Squash to "selftests/bpf: add two mptcp netns helpers"
  bpf: Add bpf_mptcpify helper
  selftests/bpf: Test bpf_mptcpify helper
  selftests/bpf: Add mptcpify selftest
