Can unix sockets be accessed without using __sock_recvmsg?

Question

I'm trying to debug an interaction between a driver and a user program that talks to each other using a unix socket. So my question is: "Is the method __sock_recvmsg (in net/socket.c) the only way data is received from a socket or are there other methods in the kernel that read data from the socket?"

Answer 1

The answer I found is kinda... If the socket is a normal unix socket then the output must go through __sock_recvmsg but it is possible to change the function that is called by the socket when receiving a message but then it's not a normal unix socket.
