on some unconventional configuration.
The MPTCP protocol is trying to create a subflow for an
unaccepted server socket. That is allowed by the RFC, even
if subflow creation will likely fail.
Unaccepted sockets have still a NULL sk_socket field,

Thank you for the patch, the addition in the code looks very good to me!
But are you sure the commit you mention introduces the issue you fix here?
Cheers,
Matt
