  Message : evdns: evdns_base_free(): fix UAF of evdns_base with @fail_requests If you call evdns_base_free() with @fail_requests == 1, then it will defer callback with DNS_ERR_SHUTDOWN, but that callback (internal) uses data->evdns_base, but we already freed that evdns base, so we can't do this, fix this by checking @result to DNS_ERR_SHUTDOWN. Fixes: regress dns/client_fail_requests_getaddrinfo Fixes: #269
