The solution is to yet again fix the kernel and put a "timestamp offset" on a socket. A socket offset is added in places where externally visible tcp timestamp option is parsed/initialized. Connections in the SYN_RECV state are not supported, global tcp_time_stamp is used for them, because repair mode doesn't support this state. In a future it can be implemented by the similar way as for TIME_WAIT sockets. For time-wait sockets offset is inhereted by a proper tcp_sock. A per-socket offset can be set only for sockets in repair mode. ==================== Signed-off-by: David S. Miller --- b8fa4100350432504df438014e2e5e9c1bbb6325
