As reported in GH #2358, #2359, #2360, #2361 and #2362: ipv6 address handling may cause memory overrun due to struct in6_addr being handled as sockaddr_in6 which is larger. Moreover, source variable wasn't properly read from since the raw value was used as a pointer instead of pointing to the actual variable's address. This bug was introduced by 6fde37e046 ("MINOR: server/event_hdl: add SERVER_INETADDR event") Unfortunately for us, gcc didn't catch this and, this actually used to "work" by accident since in6_addr struct is made of array so not passing pointer explicitly still resolved to the proper starting address.. Hopefully this was caught by coverity so thanks to Ilya for that. The fix is simple: we simply copy the whole in6_addr struct by accessing it using a pointer and using the proper struct size for the copy.
