From: Eric Dumazet <edumazet@google.com>
syzbot found a typical data-race addressed in the first patch.
While we are at it, second patch makes the global rate limit
per net-ns and disabled by default.
Eric Dumazet (2):
tcp: annotate data-race around challenge_timestamp
tcp: make global challenge ack rate limitation per net-ns and default
disabled
