Detailed Description

struct tcp_cookie_values - each socket needs extra space for the cookies, together with (optional) space for any SYN data.

A tcp_sock contains a pointer to the current value, and this is cloned to the tcp_timewait_sock.

: variable data from the option exchange.

: user specified tcpct_cookie_desired. Zero indicates default (sysctl_tcp_cookie_size). After cookie sent, remembers size of cookie. Range 0, TCP_COOKIE_MIN to TCP_COOKIE_MAX.

: user specified tcpct_s_data_desired. When the constant payload is specified (), holds its length instead. Range 0 to TCP_MSS_DESIRED.

: constant data that is to be included in the payload of SYN or SYNACK segments when the cookie option is present.
