Function Documentation

◆ dnsserv_close_listener()

void dnsserv_close_listener ( connection_t * conn )

Free the evdns server port for conn, which must be an AP_DNS_LISTENER.

Definition at line 407 of file dnsserv.c.

◆ dnsserv_configure_listener()

void dnsserv_configure_listener ( connection_t * conn )

Set up the evdns server port for the UDP socket on conn, which must be an AP_DNS_LISTENER

Definition at line 391 of file dnsserv.c.

◆ dnsserv_launch_request()

int dnsserv_launch_request	(	const char *	name,
		int	reverse,
		control_connection_t *	control_conn
	)

Helper function: called whenever the client sends a resolve request to our controller. We need to eventually answer the request req. Returns 0 if the controller will be getting (or has gotten) an event in response; -1 if we couldn't launch the request.

Definition at line 210 of file dnsserv.c.

◆ dnsserv_reject_request()

void dnsserv_reject_request ( entry_connection_t * conn )

If there is a pending request on conn that's waiting for an answer, send back an error and free the request.

Definition at line 289 of file dnsserv.c.

◆ dnsserv_resolved()

void dnsserv_resolved	(	entry_connection_t *	conn,
		int	answer_type,
		size_t	answer_len,
		const char *	answer,
		int	ttl
	)

Tell the dns request waiting for an answer on conn that we have an answer of type answer_type (RESOLVE_TYPE_IPV4/IPV6/ERR), of length answer_len, in answer, with TTL ttl. Doesn't do any caching; that's handled elsewhere.
