Function Documentation

createResponse()

int createResponse	(	struct module_qstate *	qstate,
		sldns_buffer *	pkt )

Create response according to the ldns packet content

This function fills qstate.return_msg up with data of a given packet

Parameters

qstate	module environment
pkt	a sldns_buffer which contains sldns_packet data

Returns

0 on failure, out of memory or parse error.

delegpt_addr_addr2str()

void delegpt_addr_addr2str	(	struct delegpt_addr *	target,
		char *	dest,
		int	maxlen )

invalidateQueryInCache()

void invalidateQueryInCache	(	struct module_qstate *	qstate,
		struct query_info *	qinfo )

Invalidate the message associated with query_info stored in message cache.

This function invalidates the record in message cache associated with the given query only if such a record exists.

Parameters

qstate	module environment
qinfo	query info, the query for which answer is stored.

reply_addr2str()

void reply_addr2str	(	struct comm_reply *	reply,
		char *	dest,
		int	maxlen )

Convert reply->addr to string

Parameters

reply	comm reply with address in it.
dest	destination string.
maxlen	length of string buffer.

storeQueryInCache()

int storeQueryInCache	(	struct module_qstate *	qstate,
		struct query_info *	qinfo,
		struct reply_info *	msgrep,
		int	is_referral )

Store the reply_info and query_info pair in message cache (qstate->msg_cache)

Parameters

qstate	module environment
qinfo	query info, the query for which answer is stored.
msgrep	reply in dns_msg
is_referral	If true, then the given message to be stored is a referral. The cache implementation may use this as a hint. It will store only the RRsets, not the message.

Returns

0 on alloc error (out of memory).
