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 272 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 308 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 439 of file routerset.c.

◆ routerset_free_()

void routerset_free_ ( routerset_t * routerset )

Free all storage held in routerset.

Definition at line 465 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 379 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 188 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 212 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 197 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.

Definition at line 413 of file routerset.c.

◆ 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.

◆ routerset_union()

void routerset_union	(	routerset_t *	target,
		const routerset_t *	source
	)

Add all members of the set source to target.

Variable Documentation

◆ ROUTERSET_type_defn

const struct var_type_def_t ROUTERSET_type_defn

extern

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.
