* MFC r301592truckman2016-06-151-12/+13
| | | | | | | | | | | | | | | Don't leak addrinfo if ai->ai_addrlen <= minsiz test fails. If the ai->ai_addrlen <= minsiz test fails, then freeaddrinfo() does not get called to free the memory just allocated by getaddrinfo(). Fix by moving ai->ai_addrlen <= minsiz to a separate nested if block, and keep freeaddrinfo() in the outer block so that freeaddrinfo() will be called whenever getaddrinfo() succeeds.

| | | | | | | | | | | | | | | | | | | | resolver: automatically reload /etc/resolv.conf On each resolver query, use stat(2) to see if the modification time of /etc/resolv.conf has changed. If so, reload the file and reinitialize the resolver library. However, only call stat(2) if at least two seconds have passed since the last call to stat(2), since calling it on every query could kill performance. This new behavior is enabled by default. Add a "reload-period" option to disable it or change the period of the test. Document this behavior and option in resolv.conf(5). Polish the man page just enough to appease igor.
