* Add dns.tsig.Key class.Brian Wellington2020-07-011-19/+4
| | | | | | | | | | | | | | | | | | | | This creates a new class to represent a TSIG key, containing name, secret, and algorithm. The keyring format is changed to be {name : key}, and the methods in dns.tsigkeyring are updated to deal with old and new formats. The Message class is updated to use dns.tsig.Key, although (to avoid breaking existing code), it stores them in the keyring field. Message.use_tsig() can accept either explicit keys, or keyrings; it will extract and/or create a key. dns.message.from_wire() can accept either a key or a keyring in the keyring parameter. If passed a key, it will now raise if the TSIG record in the message was signed with a different key. If passed a keyring containing keys (as opposed to bare secrets), it will check that the TSIG record's algorithm matches that of the key.

| | | | | | | errno doesn't cause the errno field in the exception to be set, and thus our exceptions were different and less useful than the stock ones. Adjust gethostbyaddr() to filter addresses like the system one does.

* Remove dns.rdata{type,class}.to_enum.Brian Wellington2020-05-211-2/+2
| | | | | | | These methods (which convert a str/int into an enum/int) shouldn't be commonly used by external code, so don't need to exist at the module level. The make() method on the enum class (renamed from to_enum()) can still be used, and the internal callers have been updated to use it.
