tcp: introduce TCP_PAWS_WRAP tcp_paws_check() uses TCP_PAWS_24DAYS constant to detect if TCP TS values might have wrapped after a long idle period. This mechanism is described in RFC 7323 5.5 (Outdated Timestamps) TCP_PAWS_24DAYS value was based on the assumption of a clock of 1 Khz. As we want to adopt a 1 Mhz clock in the future, we reduce this constant. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
