-Subject: [PATCH] stream: tcp: Handle retransmitted SYN with TSval
-
-For connections that use TCP timestamps for which the first SYN packet
-does not reach the server, any replies to retransmitted SYNs will be
-tropped.
-
-This is happening in StateSynSentValidateTimestamp, where the timestamp
-value in a SYN-ACK packet must match the one from the SYN packet.
-However, since the server never received the first SYN packet, it will
-respond with an updated timestamp from any of the following SYN packets.
-
-The timestamp value inside suricata is not being updated at any time
-which should happen. This patch fixes that problem.
-
-This problem was introduced in 9f0294fadca3dcc18c919424242a41e01f3e8318.
