* [ruby/resolv] Support a :use_ipv6 option to Resolv#initializeJeremy Evans2023-11-251-2/+15
| | | | | | | | | When set, supports returning IPv6 results even if there is no public IPv6 address for the system. Implements Ruby Feature #14922 https://github.com/ruby/resolv/commit/09d141de38
* [ruby/resolv] Support a :raise_timeout_errors option to raise timeouts as ↵Jeremy Evans2023-11-251-0/+6
| | | | | | | | | | Resolv::ResolvError This allows to differentiate a timeout from an NXDOMAIN response. Fixes [Bug #18151] https://github.com/ruby/resolv/commit/c0e5abab76
* [ruby/resolv] Fix the fallback from UDP to TCP due to message truncationJeremy Evans2023-11-241-2/+4
| | | | | | | | | | If truncation is detected, return immediately from decode so that the UDP connection can be retried with TCP, instead of failing to decode due to trying to decode a truncated response. Fixes [Bug #13513] https://github.com/ruby/resolv/commit/0de996dbca
* [ruby/resolv] Catch EPROTONOSUPPORT as a sign of no IPv6 as wellKJ Tsanaktsidis2023-11-241-1/+1
| | | | | | | | | | | | (https://github.com/ruby/resolv/pull/41) If IPv6 is disabled inside a freebsd jail, it seems this returns EPROTONOSUPPORT and not EAFNOSUPPORT. In both cases, we should simply try some other listed DNS servers. Fixes [Bug #19928] https://bugs.ruby-lang.org/issues/19928 https://github.com/ruby/resolv/commit/5e2d48708b
* [ruby/resolv] Implement dohpath SvcParamKasumi Hanazuki2023-11-241-0/+29
| | | | | | | | | | | | | | | | | | | | | | (https://github.com/ruby/resolv/pull/33) * Implement dohpath SvcParam [RFC 9461] This patch implements "dohpath" SvcParam proposed in [draft-ietf-add-svcb-dns-08]. This parameter specifies a URI template for the :path used in DNS-over-HTTPS requests. "dohpath" is employed by [DDR], also a to-be-published Proposed Standard that specifies how to upgrade DNS transport to a more secure one, i.d., DNS-over-TLS or DNS-over-HTTPS. DDR is deployed in the public DNS resolvers including Cloudflare DNS, Google Public DNS, and Quad9.

* [ruby/resolv] IPv6: update to_s method to be RFC5952 compliantJohn Bond2023-11-221-5/+1
| | | | | | | | | | | | | | | | | | | (https://github.com/ruby/resolv/pull/25) * IPv6: update to_s method to be RFC5952 compliant I noticed that the resolv library does not honour RFC 5952 Section 4.2.2. in relation to textural representation of ipv6 addresses: The symbol "::" MUST NOT be used to shorten just one 16-bit 0 field. For example, the representation 2001:db8:0:1:1:1:1:1 is correct, but 2001:db8::1:1:1:1:1 is not correct.

* [ruby/resolv] Fix confusion of received response messageKazuki Yamaguchi2021-05-111-3/+3
| | | | | | | | | | | | | | | | | | | This is a follow up for commit 33fb966197f1 ("Remove sender/message_id pair after response received in resolv", 2020-09-11). As the @senders instance variable is also used for tracking transaction ID allocation, simply removing an entry without releasing the ID would eventually deplete the ID space and cause Resolv::DNS.allocate_request_id to hang. It seems the intention of the code was to check that the received DNS message is actually the response for the question made within the method earlier. Let's have it actually do so. [Bug #12838] https://bugs.ruby-lang.org/issues/12838 [Bug #17748] https://bugs.ruby-lang.org/issues/17748 https://github.com/ruby/resolv/commit/53ca9c9209

* Add support for IPv6 link local addresses to resolvJeremy Evans2020-11-071-1/+26
| | | | | | | | | | Now that it should work correctly, test that every address returned by Socket.ip_address_list is resolvable. Socket works with IPv6 link local addresses, and ipaddr now does as well, so I think resolv should support them. Fixes [Bug #17112]
* Remove sender/message_id pair after response received in resolvJeremy Evans2020-11-071-1/+1
| | | | | | | | | Once a response for a given DNS request has been received (which requires a matching message id), the [sender, message_id] pair should be removed from the list of valid senders. This makes it so duplicate responses from the same sender are ignored. Fixes [Bug #12838]

| | | | | | | | | Resolv::DNS::Requester::UnconnectedUDP#sender Otherwise, if the IP address given is not in canonical form, it won't match, and Resolv will ignore it. Fixes [Bug #16439]
* Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans2019-11-181-4/+0
