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.
