Merge branch 'tcp-take-care-of-tcp_get_timestamping_opt_stats-races'
Eric Dumazet says:
====================
tcp: take care of tcp_get_timestamping_opt_stats() races
tcp_get_timestamping_opt_stats() does not own the socket lock,
this is intentional.
It calls tcp_get_info_chrono_stats() while other threads could
change chrono fields in tcp_chrono_set(). It also reads many
tcp socket fields that can be modified by other cpus/threads.
I do not think we need coherent TCP socket state snapshot
in tcp_get_timestamping_opt_stats().
Add READ_ONCE()/WRITE_ONCE() or data_race() annotations.
Note that icsk_ca_state is a bitfield, thus not covered
in this series.
