Hello, during build of Linux 5.6.2 (also happened on 5.5.x series)
gcc (9.3) prints following warning:
security/smack/smack_lsm.c: In function ‘smack_socket_connect’:
security/smack/smack_lsm.c:2838:24: warning: unused variable ‘sip’ [-Wunused-variable]
2838 | struct sockaddr_in6 *sip = (struct sockaddr_in6 *)sap;
My kernel has set CONFIG_IPV6=n during build.
