Handling the Reception of SYN Segments

  • Artículo

[The TCP chimney offload feature is deprecated and should not be used.]

If an offload target receives a SYN segment on an offloaded TCP connection that is in the TIME_WAIT state, the offload target should forward the segment to the host stack through the nonoffload NDIS interface by calling the NdisMIndicateReceiveNetBufferLists function.

When an offload target receives an in-order SYN segment in any state other than TIME_WAIT, the target must upload the connection in CLOSED state. An out-of-order SYN segment must trigger blind-reset attack mitigation.
