Function Documentation

◆ dirserv_orconn_tls_done()

void dirserv_orconn_tls_done ( const tor_addr_t addr,
uint16_t  or_port,
const char *  digest_rcvd,
const ed25519_public_key_t ed_id_rcvd 
)

Called when a TLS handshake has completed successfully with a router listening at address:or_port, and has yielded a certificate with digest digest_rcvd.

Inform the reachability checker that we could get to this relay.

◆ dirserv_should_launch_reachability_test()

int dirserv_should_launch_reachability_test ( const routerinfo_t ri,
const routerinfo_t ri_old 
)

Called when we, as an authority, receive a new router descriptor either as an upload or a download. Used to decide whether to relaunch reachability testing for the server.

◆ dirserv_single_reachability_test()

void dirserv_single_reachability_test ( time_t  now,
routerinfo_t router 
)

◆ dirserv_test_reachability()

void dirserv_test_reachability ( time_t  now)

Auth dir server only: load balance such that we only try a few connections per call.

The load balancing is such that if we get called once every ten seconds, we will cycle through all the tests in REACHABILITY_TEST_CYCLE_PERIOD seconds (a bit over 20 minutes).
