[PATCH mptcp-next v6 0/4] add skc_to_mptcp_sock

Posted by Geliang Tang 2 years, 1 month ago

v6:
 - add skc_to_mptcp_sock helper and test

RESEND:
 - fix the CI Build Failure.
v5:
 - fix incorrect token value
 - verify the token in selftest

v4:
 - define bpf_mptcp_sock_proto as a static function, no longer export
   it in linux/bpf.h

v3:
 - use RET_PTR_TO_BTF_ID_OR_NULL instead of RET_PTR_TO_MPTCP_SOCK_OR_NULL
 - add a new bpf_id BTF_SOCK_TYPE_MPTCP

v2:
 - keep RET_PTR_TO_MPTCP_SOCK_OR_NULL. If we use RET_PTR_TO_BTF_ID_OR_NULL
instead of RET_PTR_TO_MPTCP_SOCK_OR_NULL as Alexei suggested, the
"userspace" tests developed by Nicolas will break.

Geliang Tang (4):
  Revert "selftests: bpf: add bpf_mptcp_sock() verifier tests"
  Revert "bpf: add 'bpf_mptcp_sock' structure and helper"
  bpf: add skc_to_mptcp_sock helper
  selftests: bpf: add skc_to_mptcp_sock test
