49 * selinux_netlbl_inode_permission - Verify the socket is NetLabel labeled

53 * Description:
54 * Looks at a file's inode and if it is marked as a socket protected by
55 * NetLabel then verify that the socket has been labeled, if not try to label
56 * the socket now with the inode's SID. Returns zero on success, negative
57 * values on failure.
