DESCRIPTION

ldns_dnssec_trust_tree_new() Creates a new (empty) dnssec_trust_tree structure .br Returns ldns_dnssec_trust_tree *

ldns_dnssec_trust_tree_free() Frees the dnssec_trust_tree recursively There is no deep free; all data in the trust tree consists of pointers to a data_chain .br tree: The tree to free

ldns_dnssec_trust_tree_depth() returns the depth of the trust tree .br tree: tree to calculate the depth of .br Returns The depth of the tree

ldns_dnssec_derive_trust_tree() Generates a dnssec_trust_tree for the given rr from the given data_chain This does not clone the actual data; Don't free the data_chain before you are done with this tree .br *data_chain: The chain to derive the trust tree from .br *rr: The RR this tree will be about .br Returns ldns_dnssec_trust_tree *

ldns_dnssec_trust_tree_contains_keys() Returns OK if there is a trusted path in the tree to one of the DNSKEY or DS RRs in the given list \param *tree The trust tree so search \param *keys A ldns_rr_list of DNSKEY and DS rrs to look for .br Returns LDNS_STATUS_OK if there is a trusted path to one of the keys, or the *first* error encountered if there were no paths

ldns_dnssec_trust_tree_print() Prints the dnssec_trust_tree structure to the given file stream. If a link status is not LDNS_STATUS_OK; the status and relevant signatures are printed too .br *out: The file stream to print to .br tree: The trust tree to print .br tabs: Prepend each line with tabs*2 spaces .br extended: If true, add little explanation lines to the output

ldns_dnssec_trust_tree_print_sm()

ldns_dnssec_trust_tree_add_parent() Adds a trust tree as a parent for the given trust tree .br *tree: The tree to add the parent to .br *parent: The parent tree to add .br *parent_signature: The RRSIG relevant to this parent/child connection .br parent_status: The DNSSEC status for this parent, child and RRSIG .br Returns LDNS_STATUS_OK if the addition succeeds, error otherwise

ldns_dnssec_derive_trust_tree_normal_rrset() Sub function for derive_trust_tree that is used for a 'normal' rrset .br new_tree: The trust tree that we are building .br data_chain: The data chain containing the data for the trust tree .br cur_sig_rr: The currently relevant signature

ldns_dnssec_derive_trust_tree_dnskey_rrset() Sub function for derive_trust_tree that is used for DNSKEY rrsets .br new_tree: The trust tree that we are building .br data_chain: The data chain containing the data for the trust tree .br cur_rr: The currently relevant DNSKEY RR .br cur_sig_rr: The currently relevant signature

ldns_dnssec_derive_trust_tree_ds_rrset() Sub function for derive_trust_tree that is used for DS rrsets .br new_tree: The trust tree that we are building .br data_chain: The data chain containing the data for the trust tree .br cur_rr: The currently relevant DS RR

ldns_dnssec_derive_trust_tree_no_sig() Sub function for derive_trust_tree that is used when there are no signatures .br new_tree: The trust tree that we are building .br data_chain: The data chain containing the data for the trust tree
