TCP_CC_INFO is a new socket option to get congestion control info without netlink (union tcp_cc_info is in linux/inet_diag.h kernel header). linux commit 6e9250f59ef9efb932c84850cd221f22c2a03c4a TCP_SAVE_SYN, TCP_SAVED_SYN socket options are for saving and getting the SYN headers of passive connections in a server application. linux commit cd8ae85299d54155702a56811b2e035e63064d3d Add new tcpi_* fields to struct tcp_info implementing RFC4898 counters. linux commit 2efd055c53c06b7e89c167c98069bab9afce7e59
