[PATCH mptcp-net v2 0/4] mptcp: fix races in add_addr handling

[Paolo Abeni <pabeni@redhat.com>]

the patches 1 && 2 fix actual races, even if the race addressed by
2/4 is not exposed by the self-tests, afaics.

patch 3 introduces some mibs to detect critical scenarios we can't
fix without major rework

patch 4 updates the self-test to be graceful in above cases.

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/254

  mptcp: fix race in overlapping signal events
