Subject: [PATCH net-next 0/2] tcp: change reaction to ICMP messages

ICMP[v6] messages received for a socket in TCP_SYN_SENT currently abort
the connection attempt, in violation of standards.

This series changes our stack to adhere to RFC 6069 and RFC 1122 (4.2.3.9)

Eric Dumazet (2):
  tcp: use tp->total_rto to track number of linear timeouts in SYN_SENT
    state
  tcp: no longer abort SYN_SENT when receiving some ICMP
