2024-02-29[ruby/resolv] Implement CAA resource recordKasumi Hanazuki
This patch implements handling of CAA resource records defined by [RFC8659]. - There are no known deployment of CAA records outside of IN (Internet), but the RFC does not state that CAA records are class-specific. Thus `CAA` class is defined as a class-independent RRType. - `CAA` class stores `flags` field (a 1-octet bitset) as an Integer. In this way it's easier to ensure the encoded RR is in the valid wire format.

2023-11-25[ruby/resolv] Support a :use_ipv6 option to Resolv#initializeJeremy Evans
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
2023-11-25[ruby/resolv] Support a :raise_timeout_errors option to raise timeouts as ↵Jeremy Evans
Resolv::ResolvError This allows to differentiate a timeout from an NXDOMAIN response. Fixes [Bug #18151] https://github.com/ruby/resolv/commit/c0e5abab76
2023-11-24[ruby/resolv] Fix the fallback from UDP to TCP due to message truncationJeremy Evans
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
2023-11-24[ruby/resolv] Catch EPROTONOSUPPORT as a sign of no IPv6 as wellKJ Tsanaktsidis
(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
2023-11-24[ruby/resolv] Implement dohpath SvcParamKasumi Hanazuki
(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.

2023-11-24[ruby/resolv] Implement SVCB and HTTPS RRsKasumi Hanazuki
(https://github.com/ruby/resolv/pull/32) * Add MessageDecoder#get_list This method repeats yielding until all the data upto the current limit is consumed, and then returns an Array containig the block results. * Implement SVCB and HTTPS RRs [RFC 9460] > This patch implements SVCB and HTTPS resource record types defined in > [RFC 9460]. > > The RR types are now supported by many server implementations including > BIND, unbound, PowerDNS, and Knot DNS.

2023-11-22[ruby/resolv] IPv6: update to_s method to be RFC5952 compliantJohn Bond
(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.

2021-05-11[ruby/resolv] Fix confusion of received response messageKazuki Yamaguchi
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

2020-11-07Support s390 IPv6 link local addressesJeremy Evans
2020-11-07Add support for IPv6 link local addresses to resolvJeremy Evans
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] Notes: Merged: https://github.com/ruby/ruby/pull/3452
2020-11-07Remove sender/message_id pair after response received in resolvJeremy Evans
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] Notes: Merged: https://github.com/ruby/ruby/pull/3536
2020-05-29Convert ip addresses to canonical form in ↵Jeremy Evans
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] Notes: Merged: https://github.com/ruby/ruby/pull/3161
2019-11-18Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans
This removes the related tests, and puts the related specs behind version guards. This affects all code in lib, including some libraries that may want to support older versions of Ruby. Notes: Merged: https://github.com/ruby/ruby/pull/2476
