You are on the right track, that reading directory entries (like in dirent()) is provided as read operation on directory nodes. Please have a look at os/src/lib/vfs/fs_file_system.h for an implementation of dirent(). The trick is to use n * sizeof(::File_system::Directory_entry) as file_offset parameter to read the n-th entry.
