In the main.c file, there is a comment saying that 'we need to open fifo before do_suid() and start the fifo server after all the socket are initialized, to inherit them'. I'm wondering why SER has to do it like that. Can't SER lower its privileges first (do_suid), then open fifo and start the fifo server? The reason being that I want to run SER with an unprivileged user. With the current implementation, the fifo file will be created by root which is not accessible to anyone else. Unless I change the fifo_mode to 0666, which I don't want to, I can't make SER more secure and yet accessible. I've tried to move the do_suid() before init_fifo_server() and compile successfully. The server can run as ser:apache with fifo_mode set to 0660. That way, my Apache server can talk to SER yet limiting other user directly talking to SER via serctl. However, I would like to know the reason why it is implemented the way it is now. Maybe I'm not insightful to see the obviously reason. Also, will unix_sock get something like unix_sock_mode in the future?
