Public bug reported: First, sorry for my bad english.
The issue is that Linux-based OS sometimes can't make an tcp connection to some Windows servers with switched on buggy implementation of rfc1323, that described on this forum: http://www.network-builders.com /windows-tcp-timestamp-not-compliant-rfc-1323-a-t80898.html. Because some Windows hosts implementation of rfc1323 bases on randomly generated TSval and sent first value of TSval as 0, the difference of recent and new TSval sometimes has been affected by a sign magic issue and the PAWS mechanism has been triggered. Anyway, the rfc1323 has discribes the condition of PAWS as "0 < (t - s) < 2**31", that has been right implementation in current linux kernel, but incompatible with Windows bug. For example, the one of affected to this issue Windows host is behind relay.n-l-e.ru:80. Note that problems arise only when the remote side sets the TC val > 2147483647, ie when there is a sign. I think that my small patch makes the kernel more compatible with this windows bug.
