[ruby/resolv] Fix confusion of received response message

2021-05-11T03:37:34+00:00

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.

`fe80` should be case insensitive too

Support s390 IPv6 link local addresses

Add support for IPv6 link local addresses to resolv

2020-11-07T21:47:45+00:00

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.

Remove sender/message_id pair after response received in resolv

2020-11-07T21:12:27+00:00

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.

Convert ip addresses to canonical form in Resolv::DNS::Requester::UnconnectedUDP#sender

2020-05-29T22:59:27+00:00

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-ops

2019-11-17T23:00:25+00:00

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.

Fallback to TCP in resolv if UDP bind raises EACCES
