Revision 21e43569685de4ad773fb060c11a15f3fd5e7ac4 authored by Paolo Abeni on 07 February 2023, 13:04:14 UTC, committed by David S. Miller on 08 February 2023, 09:39:34 UTC
We need to call the __mptcp_nmpc_socket(), and later subflow socket
access under the msk socket lock, or e.g. a racing connect() could
change the socket status under the hood, with unexpected results.
Fixes: 54635bd04701 ("mptcp: add TCP_FASTOPEN_CONNECT socket option")
