Make data members private and convert functions for adding and checking user and initiator authentication into class methods. Use std::string to store the label for an auth_group and add a label() method to retrieve a const C string version for logging. Replace AG_TYPE_* macros with a scoped enum. Replace the TAILQ of auth_group objects in struct conf with an unordered_map<> of named auth_group objects. Anonymous auth_group objects for targets are no longer stored in a global data structure. Since a target can have a pointer to either named or anonymous objects, use a shared_ptr<> to store references to auth_group objects. Use the shared_ptr<>'s reference count to determine if a named auth_group is unused in conf_verify() instead of walking all the linked lists to check for references. While here, avoid making a second copy of socket address for a client and instead just store a pointer in ctld_connection.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
