57 ldns_dnssec_trust_tree_new() Creates a new (empty) dnssec_trust_tree
58 structure
59 Returns ldns_dnssec_trust_tree *
61 ldns_dnssec_trust_tree_free() Frees the dnssec_trust_tree recursively
63 There is no deep free; all data in the trust tree consists of
65 pointers to a data_chain
66 tree: The tree to free
68 ldns_dnssec_trust_tree_depth() returns the depth of the trust tree
70 tree: tree to calculate the depth of
72 Returns The depth of the tree
73 ldns_dnssec_derive_trust_tree() Generates a dnssec_trust_tree for the
75 given rr from the given data_chain
76 This does not clone the actual data; Don't free the data_chain
78 before you are done with this tree
79 *data_chain: The chain to derive the trust tree from
81 *rr: The RR this tree will be about
82 Returns ldns_dnssec_trust_tree *
83 ldns_dnssec_trust_tree_contains_keys() Returns OK if there is a trusted
85 path in the tree to one of the DNSKEY or DS RRs in the given
86 list
87 \param *tree The trust tree so search \param *keys A
89 ldns_rr_list of DNSKEY and DS rrs to look for
90 Returns LDNS_STATUS_OK if there is a trusted path to one of the
92 keys, or the *first* error encountered if there were no paths
93 ldns_dnssec_trust_tree_print() Prints the dnssec_trust_tree structure
95 to the given file stream.
96 If a link status is not LDNS_STATUS_OK; the status and relevant
98 signatures are printed too
99 *out: The file stream to print to
101 tree: The trust tree to print
102 tabs: Prepend each line with tabs*2 spaces
103 extended: If true, add little explanation lines to the output
104 ldns_dnssec_trust_tree_print_sm()
106 ldns_dnssec_trust_tree_add_parent() Adds a trust tree as a parent for
108 the given trust tree
109 *tree: The tree to add the parent to
111 *parent: The parent tree to add
112 *parent_signature: The RRSIG relevant to this parent/child con‐
113 nection
114 parent_status: The DNSSEC status for this parent, child and
115 RRSIG
116 Returns LDNS_STATUS_OK if the addition succeeds, error otherwise
117 ldns_dnssec_derive_trust_tree_normal_rrset() Sub function for de‐
119 rive_trust_tree that is used for a 'normal' rrset
120 new_tree: The trust tree that we are building
122 data_chain: The data chain containing the data for the trust
123 tree
124 cur_sig_rr: The currently relevant signature
125 ldns_dnssec_derive_trust_tree_dnskey_rrset() Sub function for de‐
127 rive_trust_tree that is used for DNSKEY rrsets
128 new_tree: The trust tree that we are building
130 data_chain: The data chain containing the data for the trust
131 tree
132 cur_rr: The currently relevant DNSKEY RR
133 cur_sig_rr: The currently relevant signature
134 ldns_dnssec_derive_trust_tree_ds_rrset() Sub function for de‐
136 rive_trust_tree that is used for DS rrsets
137 new_tree: The trust tree that we are building
139 data_chain: The data chain containing the data for the trust
140 tree
141 cur_rr: The currently relevant DS RR
142 ldns_dnssec_derive_trust_tree_no_sig() Sub function for de‐
144 rive_trust_tree that is used when there are no signatures
145 new_tree: The trust tree that we are building
147 data_chain: The data chain containing the data for the trust
148 tree
