Detailed Description

This file contains the functions for an authority zone.

This zone is queried by the iterator, just like a stub or forward zone, but then the data is locally held.

Cleanup auth zones.

This removes all events from event bases. Stops the xfr tasks. But leaves zone data.

Parameters

		struct regional *	region,
		struct dns_msg **	msg,
		int *	fallback,
		uint8_t *	dp_nm,
		size_t	dp_nmlen
	)

Use auth zones to lookup the answer to a query.

The query is from the iterator. And the auth zones attempts to provide the answer instead of going to the internet.

Parameters

az	auth zones structure.
qinfo	query info to lookup.
region	region to use to allocate the reply in.
msg	reply is stored here (if one).
fallback	if true, fallback to making a query to the internet.
dp_nm	name of delegation point to look for. This zone is used to answer the query. If the dp_nm is not found, fallback is set to true and false returned.
dp_nmlen	length of dp_nm.

Returns: 0: failure (an error of some sort, like servfail). if 0 and fallback is true, fallback to the internet. if 0 and fallback is false, like getting servfail. If true, an answer is available.
