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 *parents[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS];

       ldns_status parent_status[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS];

       /** for debugging, add signatures too (you might want

        those if they contain errors) */

       ldns_rr *parent_signature[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS];

       size_t parent_count;

};
