Detailed Description

This file contains functions to assist the iterator module.

Keep track of the private addresses and lookup fast.

Function Documentation

priv_create()

struct iter_priv* priv_create

(

void

)

Create priv structure.

Returns

new structure or NULL on error.

Referenced by iter_apply_cfg().

priv_delete()

void priv_delete

(

struct iter_priv *

priv

)

Delete priv structure.

Parameters

priv	to delete.

References iter_priv::region, and regional_destroy().

Referenced by iter_deinit(), and priv_create().

priv_apply_cfg()

int priv_apply_cfg	(	struct iter_priv *	priv,
		struct config_file *	cfg
	)

Process priv config.

Parameters

priv	where to store.
cfg	config options.

Returns

0 on error.

priv_rrset_bad()

int priv_rrset_bad	(	struct iter_priv *	priv,
		struct sldns_buffer *	pkt,
		struct rrset_parse *	rrset
	)

See if rrset is bad.

Will remove individual RRs that are bad (if possible) to sanitize the RRset without removing it completely.

Parameters

priv	structure for private address storage.
pkt	packet to decompress rrset name in.
rrset	the rrset to examine, A or AAAA.

Returns

true if the rrset is bad and should be removed.

priv_get_mem()

size_t priv_get_mem

(

struct iter_priv *

priv

)

Get memory used by priv structure.

Parameters

priv	structure for address storage.

Returns

bytes in use.
