The tree only contains pointers to the .br data_chain, and therefore one should *never* free() the .br data_chain when there is still a trust tree derived from .br that chain. .br .br Example tree: .br key key key .br \\ | / .br \\ | / .br \\ | / .br ds .br | .br key .br | .br key .br | .br rr .br .br For each signature there is a parent; if the parent .br pointer is null, it couldn't be found and there was no .br denial; otherwise is a tree which contains either a .br DNSKEY, a DS, or a NSEC rr .br struct ldns_dnssec_trust_tree_struct .br { .br ldns_rr *rr; .br /* the complete rrset this rr was in */ .br ldns_rr_list *rrset; .br ldns_dnssec_trust_tree *parents[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS]; .br ldns_status parent_status[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS]; .br /** for debugging, add signatures too (you might want .br those if they contain errors) */ .br ldns_rr *parent_signature[LDNS_DNSSEC_TRUST_TREE_MAX_PARENTS]; .br size_t parent_count; .br }; .br .br typedef struct ldns_dnssec_trust_tree_struct ldns_dnssec_trust_tree; .PP .SH AUTHOR The ldns team at NLnet Labs. .SH REPORTING BUGS Please report bugs to dns-team@nlnetlabs.nl or on GitHub at https://github.com/NLnetLabs/ldns/issues .SH COPYRIGHT Copyright (c) 2004 - 2006 NLnet Labs. .PP Licensed under the BSD License.
