srcip_matches() previously had code like this:
srcip_matches(..., struct sockaddr *rhs) {
/* ... */
struct sockaddr_in6 *vaddr6 = (struct sockaddr_in6 *) &rhs;
return ipv6_addr_equal(..., &vaddr6->sin6_addr);
}
which interpreted the values on the stack after the 'rhs' pointer as an
ipv6 address. The correct thing to do is to use 'rhs', not '&rhs'.
