Function Documentation

◆ routerset_add_unknown_ccs()

int routerset_add_unknown_ccs ( routerset_t **  setp,
int  only_if_some_cc_set 
)

If *setp includes at least one country code, or if only_some_cc_set is 0, add the ?? and A1 country codes to *setp, creating it as needed. Return true iff *setp changed.

Definition at line 257 of file routerset.c.

◆ routerset_contains_extendinfo()

int routerset_contains_extendinfo ( const routerset_t *  set,
const extend_info_t ei 
)

Return true iff we can tell that ei is a member of set.

Definition at line 293 of file routerset.c.

◆ routerset_contains_node()

int routerset_contains_node ( const routerset_t *  set,
const node_t node 
)

Return true iff node is in set.

◆ routerset_contains_router()

int routerset_contains_router ( const routerset_t *  set,
const routerinfo_t ri,
country_t  country 
)

Return true iff ri is in set. If country is -1, we look up the country.

◆ routerset_contains_routerstatus()

int routerset_contains_routerstatus ( const routerset_t *  set,
const routerstatus_t rs,
country_t  country 
)

Return true iff rs is in set. If country is -1, we look up the country.

◆ routerset_equal()

int routerset_equal ( const routerset_t *  old,
const routerset_t *  new 
)

Helper: return true iff old and new are both NULL, or both non-NULL equal routersets.

Definition at line 424 of file routerset.c.

◆ routerset_free_()

void routerset_free_ ( routerset_t *  routerset)

Free all storage held in routerset.

Definition at line 450 of file routerset.c.

◆ routerset_get_all_nodes()

void routerset_get_all_nodes ( smartlist_t out,
const routerset_t *  routerset,
const routerset_t *  excludeset,
int  running_only 
)

Add every known node_t that is a member of routerset to out, but never add any that are part of excludeset. If running_only, only add the running ones.

Definition at line 364 of file routerset.c.

◆ routerset_is_empty()

int routerset_is_empty ( const routerset_t *  set)

Return true iff there are no entries in set.

Referenced by addressmap_clear_excluded_trackexithosts(), and routerset_equal().

◆ routerset_is_list()

int routerset_is_list ( const routerset_t *  set)

Return true iff set lists only nicknames and digests, and includes no IP ranges or countries.

Definition at line 187 of file routerset.c.

Referenced by routerset_get_all_nodes().

◆ routerset_len()

int routerset_len ( const routerset_t *  set)

Return the number of entries in set. This does NOT return a negative value.

Definition at line 211 of file routerset.c.

◆ routerset_needs_geoip()

int routerset_needs_geoip ( const routerset_t *  set)

Return true iff we need a GeoIP IP-to-country database to make sense of set.

Definition at line 196 of file routerset.c.

Referenced by options_need_geoip_info().

◆ routerset_new()

routerset_t* routerset_new ( void  )

Return a new empty routerset.

Definition at line 51 of file routerset.c.

◆ routerset_parse()

int routerset_parse ( routerset_t *  target,
const char *  s,
const char *  description 
)

Parse the string s to create a set of routerset entries, and add them to target. In log messages, refer to the string as description. Return 0 on success, -1 on failure.

Three kinds of elements are allowed in routersets: nicknames, IP address patterns, and fingerprints. They may be surrounded by optional space, and must be separated by commas.

◆ routerset_refresh_countries()

void routerset_refresh_countries ( routerset_t *  target)

Update the routerset's countries bitarray_t. Called whenever the GeoIP IPv4 database is reloaded.

◆ routerset_subtract_nodes()

void routerset_subtract_nodes ( smartlist_t lst,
const routerset_t *  routerset 
)

Remove every node_t from lst that is in routerset.

◆ routerset_to_string()

char* routerset_to_string ( const routerset_t *  set)

Return a new string that when parsed by routerset_parse_string() will yield set.

Variable Documentation

◆ ROUTERSET_type_defn

const struct var_type_def_t ROUTERSET_type_defn

Definition of a routerset_t-based configuration type.

Values are mapped to and from strings using the format defined in routerset_parse(): nicknames, IP address patterns, and fingerprints–with optional space, separated by commas.

Empty sets are represented as NULL.
