getaddrinfo memory leak

Question

I have this code for getting information about IPv4 address:

struct addrinfo hints, *info = NULL;
char addr4[INET_ADDRSTRLEN];

memset(&hints, 0, sizeof(h         


        

Answer 1

Looking a bit the gblic, it's about object catching in case of ipv6 (look 249 line).

As other members have explained, "still reachable" is not an error itself, but it may hide some buggy situations. In this case it's not a problem, just a warning about something that could hide something nasty.

This warning has also been reported to redhat

The reason of the warning for google and not for ubuntu it's beacause google has ipv6 deployed on its servers and ubuntu not, and then the catching is not performed. You can check it with:

nslookup -q=AAAA www.google.com
nslookup -q=AAAA www.ubuntu.com
