I am trying to understand IPsec and found some related subfolders: crypto, net/key, net/xfrm, net/netlink and it may be more folders and files involved in the process.
Would anyone please tell me how is the flow of network(internet) information(traffic) from a user process to the deepest layers of the kernel only by the name of the most important files and folders in case of IPsec and a typical TCP, IP(and IPsec) and Ethernet adaptor senario?
For example: setkey(shell command)--> ....(some intermediate processes)-->crypto(setkey method)
I guess it should be: net/ipv4-->net/key-->net/xfrm-->crypto net/ipv4-->net/core-->net/core/dev.c
What is netlink, is it a kind of socket? how does it become connected to IPsec?
