NAME
ldns_dnssec_data_chain, ldns_dnssec_data_chain_struct, ldns_dnssec_trust_tree
SYNOPSIS
#include <stdint.h> #include <stdbool.h> #include <ldns/ldns.h> ldns_dnssec_data_chain_struct();
DESCRIPTION
- ldns_dnssec_data_chain
- Chain structure that contains all DNSSEC data needed to
verify an rrset
struct ldns_dnssec_data_chain_struct
{ldns_rr_list *rrset;
ldns_rr_list *signatures;
ldns_rr_type parent_type;
ldns_dnssec_data_chain *parent;
ldns_pkt_rcode packet_rcode;
ldns_rr_type packet_qtype;
bool packet_nodata; - };
- typedef struct ldns_dnssec_data_chain_struct ldns_dnssec_data_chain;
- ldns_dnssec_data_chain_struct()
- ldns_dnssec_trust_tree
- Tree structure that contains the relation of DNSSEC data,
and their cryptographic status. - This tree is derived from a data_chain, and can be used
to look whether there is a connection between an RRSET
and a trusted key. The tree only contains pointers to the
data_chain, and therefore one should *never* free() the
data_chain when there is still a trust tree derived from
that chain. - Example tree:
key key key\ | /\ | /\ | /ds
|key|key|
rr - For each signature there is a parent; if the parent
pointer is null, it couldn't be found and there was no
denial; otherwise is a tree which contains either a
DNSKEY, a DS, or a NSEC rr
struct ldns_dnssec_trust_tree_struct
{ - ldns_rr *rr;
/* the complete rrset this rr was in */
ldns_rr_list *rrset;
ldns_dnssec_trust_tree *par - ents[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS];
- ldns_status parent_status[LDNS_DNSSEC_TRUST_TREE_MAX_PAR
- ENTS];
- /** for debugging, add signatures too (you might want
those if they contain errors) */
- ldns_rr *parent_signature[LDNS_DNSSEC_TRUST_TREE_MAX_PAR
- ENTS];
- size_t parent_count;
- };
- typedef struct ldns_dnssec_trust_tree_struct ldns_dnssec_trust_tree;
