Subash Abhinov Kasiviswanathan a2cbb16039 tcp: Update window clamping condition ... This patch is based on the discussions between Neal Cardwell and Eric Dumazet in the link https://lore.kernel.org/netdev/20240726204105.1466841-1-quic_subashab@quicinc.com/ It was correctly pointed out that tp->window_clamp would not be updated in cases where net.ipv4.tcp_moderate_rcvbuf=0 or if (copied <= tp->rcvq_space.space). While it is expected for most setups to leave the sysctl enabled, the latter condition may not end up hitting depending on the TCP receive queue size and the pattern of arriving data. The updated check should be hit only on initial MSS update from TCP_MIN_MSS to measured MSS value and subsequently if there was an update to a larger value.
