The logic to make configuration changes in ldpd is as follows: 1 - duplicate the current configuration; 2 - modify the duplicated configuration (delta); 3 - merge the duplicated configuration into the current configuration. We can however change things a little bit in order to simplify the code. If we provide a global vty_conf variable and make sure that it's always an up-to-date duplicate of ldpd_conf, then we don't need to call ldp_dup_config() in the callback of each configuration command. Instead of that, we just need to duplicate ldpd_conf in the startup of the daemon and in the end of the ldp_reload() function. Doing this is safe because, due to the single-threaded nature of the parent process, it's impossible to have multiple requests to change the configuration at the same time. Also, we can remove the *_ref() functions and do something much simpler instead. The problem we have to deal with here is that VTY_GET_CONTEXT() returns a pointer to an element of ldpd_conf, and what we want is a pointer to an element of vty_conf (e.g. an l2vpn). To solve this, we just need to look for the equivalent element inside vty_conf using standard functions from ldpd like l2vpn_find() and others.
