What is the reason for checking mss with 1<<rcv_wscale? include/net/tcp.h: static inline void tcp_select_initial_window(int __space, __u32 mss, __u32 *rcv_wnd, __u32 *window_clamp, int wscale_ok, __u

Because the advertised window field is 16-bits. It is interpreted as "value << rcv_wscale"

Thanks, still it is unclear to me why are we downsizing the advertised window(rcv_wnd) to cwnd? To defeat disobeying sender, or something like below? Suppose when wscale is zero, it is now checking

There is never any reason to advertise a receive window larger than the initial congestion window of the sender could ever be. Setting it properly like this also makes sure that we do receive window

That makes sense! But are we coping with cwnd increase on sender? Looks rcv rwnd s updated by only 1 pkt at time. Thanks, Prasanna.
