mptcp: mptcp_parse_option() fix for MPTCPOPT_MP_JOIN
mptcp_parse_option() currently sets OPTIONS_MPTCP_MPJ, for the three
possible cases handled for MPTCPOPT_MP_JOIN option.
OPTIONS_MPTCP_MPJ is the combination of three flags:
- OPTION_MPTCP_MPJ_SYN
- OPTION_MPTCP_MPJ_SYNACK
- OPTION_MPTCP_MPJ_ACK
This is a problem, because backup, join_id, token, nonce and/or hmac fields
could be left uninitialized in some cases.
Distinguish the three cases, as following patches will need this step.
Fixes: f296234c98a8 ("mptcp: Add handling of incoming MP_JOIN requests")
