* Don't leak addrinfo if ai->ai_addrlen <= minsiz test fails.truckman2016-06-081-12/+13
| | | | | | | | | | | | | | 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: preserve binary compatibility; reduce header pollutionvangyzen2015-12-141-15/+11
| | | | | | | | | | | | | | In r289315, I added new fields to res_state. This broke binary backward compatibility. It also broke some ports (and possibly other code) by requiring the definition of time_t and struct timespec. Fix these problems by moving the new fields into __res_state_ext.

* resolver: automatically reload /etc/resolv.confvangyzen2015-10-141-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | 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. https://lists.freebsd.org/pipermail/freebsd-arch/2015-October/017342.html Reviewed by: kp, wblock Discussed with: jilles, imp, alfred MFC after: 1 month Relnotes: yes Sponsored by: Dell Inc.
