+ * in the associated inode. Typically, the inode alloc_security hook will

+ * @sock contains the socket structure.
+ * @backlog contains the maximum length for the pending connection queue.
+ * Return 0 if permission is granted.
+ * @socket_accept:
+ * Check permission before accepting a new connection. Note that the new
+ * socket, @newsock, has been created and some information copied to it,
+ * but the accept operation has not actually been performed.
+ * @sock contains the listening socket structure.
+ * @newsock contains the newly created server socket for connection.
