Function Documentation

router_parse_addr_policy()

addr_policy_t* router_parse_addr_policy	(	directory_token_t *	tok,
		unsigned	fmt_flags
	)

Given a K_ACCEPT[6] or K_REJECT[6] token and a router, create and return a new exit_policy_t corresponding to the token. If TAPMP_EXTENDED_STAR is set in fmt_flags, K_ACCEPT6 and K_REJECT6 tokens followed by * expand to IPv6-only policies, otherwise they expand to IPv4 and IPv6 policies

router_parse_addr_policy_item_from_string()

addr_policy_t* router_parse_addr_policy_item_from_string	(	const char *	s,
		int	assume_action,
		int *	malformed_list
	)

Parse the addr policy in the string s and return it. If assume_action is nonnegative, then insert its action (ADDR_POLICY_ACCEPT or ADDR_POLICY_REJECT) for items that specify no action.

Returns NULL on policy errors.

Set *malformed_list to true if the entire policy list should be discarded. Otherwise, set it to false, and only this item should be ignored on error - the rest of the policy list can continue to be processed and used.

The addr_policy_t returned by this function can have its address set to AF_UNSPEC for '*'. Use policy_expand_unspec() to turn this into a pair of AF_INET and AF_INET6 items.

router_parse_addr_policy_private()

static addr_policy_t * router_parse_addr_policy_private ( directory_token_t *  tok )

static

Parse an exit policy line of the format "accept[6]/reject[6] private:...". This didn't exist until Tor 0.1.1.15, so nobody should generate it in router descriptors until earlier versions are obsolete.

accept/reject and accept6/reject6 private all produce rules for both IPv4 and IPv6 addresses.
