clang correctly points out a code path that would lead
to an uninitialized variable use:
security/selinux/netlabel.c:310:6: error: variable 'addr' is used uninitialized whenever 'if' condition is false
[-Werror,-Wsometimes-uninitialized]
if (ip_hdr(skb)->version == 4) {
^~~~~~~~~~~~~~~~~~~~~~~~~
security/selinux/netlabel.c:322:40: note: uninitialized use occurs here
rc = netlbl_conn_setattr(ep->base.sk, addr, &secattr);
^~~~
security/selinux/netlabel.c:310:2: note: remove the 'if' if its condition is always true
if (ip_hdr(skb)->version == 4) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
security/selinux/netlabel.c:291:23: note: initialize the variable 'addr' to silence this warning
struct sockaddr *addr;
^
= NULL
This is probably harmless since we should not see ipv6 packets
of CONFIG_IPV6 is disabled, but it's better to rearrange the code
so this cannot happen.
