Detailed Description

Implement next generation hidden service client functionality.

Function Documentation

hs_client_note_connection_attempt_succeeded()

void hs_client_note_connection_attempt_succeeded

(

const edge_connection_t *

conn

)

A circuit just finished connecting to a hidden service that the stream conn has been waiting for. Let the HS subsystem know about this.

Here is the call graph for this function:

hs_client_refetch_hsdesc()

int hs_client_refetch_hsdesc

(

const ed25519_public_key_t *

identity_pk

)

Launch a connection to a hidden service directory to fetch a hidden service descriptor using identity_pk to get the necessary keys.

A hs_client_fetch_status_t code is returned.

MOCK_IMPL()

MOCK_IMPL	(	STATIC	hs_client_fetch_status_t,
		fetch_v3_desc	,
		(const ed25519_public_key_t *onion_identity_pk)
	)

Fetch a v3 descriptor using the given onion_identity_pk.

On success, HS_CLIENT_FETCH_LAUNCHED is returned. Otherwise, an error from hs_client_fetch_status_t is returned.

Here is the call graph for this function:

pick_hsdir_v3()

STATIC routerstatus_t* pick_hsdir_v3

(

const ed25519_public_key_t *

onion_identity_pk

)

Return the HSDir we should use to fetch the descriptor of the hidden service with identity key onion_identity_pk.

Here is the call graph for this function:
