H A Dprotocol.cdiff 1b1b43ee7a208096ecd79e626f2fc90d4a321111 Wed May 31 14:37:06 CDT 2023 Paolo Abeni <pabeni@redhat.com> mptcp: fix data race around msk->first access

The first subflow socket is accessed outside the msk socket lock
by mptcp_subflow_fail(), we need to annotate each write access
with WRITE_ONCE, but a few spots still lacks it.

Fixes: 76a13b315709 ("mptcp: invoke MP_FAIL response when needed")
