Function call relationships in the tcp protocol stack during tcp three-way handshake in the Linux kernel-Linux general technology-Linux programming and kernel information. For more information, see the following. Recently, I need to modify a set of tcp protocol stacks. I simply looked at the function calling process of the kernel tcp protocol stack. It is just a rough process and I did not make a detailed investigation, take a closer look at the changes. in addition, I only read the tcp part, and none of the following ip addresses is viewed.
Here we will briefly talk about the function call relationship of the three-way handshake that begins with the tcp connection:
If you have not received a response for a while:
Tcp_retransmit_timer-> tcp_retransmit_skb-> tcp_transmit_skb
The other operations are the same as above.
The above is the description of the function call relationship in the tcp protocol stack of the three-way handshake. Due to the rush in sorting, some problems may exist.
