Subtype of edge_connection_t for an "entry connection" – that is, a SOCKS connection, a DNS request, a TransPort connection or a NATD connection
Definition at line 19 of file entry_connection_st.h.
char* chosen_exit_name |
Nickname of planned exit node – used with .exit support.

unsigned int chosen_exit_optional |
For AP connections only. If 1, and we fail to reach the chosen exit, stop requiring it.
Definition at line 83 of file entry_connection_st.h.
Referenced by circuit_discard_optional_exit_enclaves().
unsigned int chosen_exit_retries |
For AP connections only. If non-zero, this exit node was picked as a result of the TrackHostExit, and the value decrements every time we fail to complete a circuit to our chosen exit – if it reaches zero, abandon the associated mapaddress.

struct evdns_server_request* dns_server_request |
If this is a DNSPort connection, this field holds the pending DNS request that we're going to try to answer.

struct edge_connection_t edge_ |
Definition at line 20 of file entry_connection_st.h.
entry_port_cfg_t entry_cfg |
Definition at line 31 of file entry_connection_st.h.
unsigned int hs_with_pow_conn |
True iff this is a connection to a HS that has PoW defenses enabled, so we know not to apply the usual SOCKS timeout.
Definition at line 102 of file entry_connection_st.h.
Referenced by connection_ap_expire_beginning(), and connection_ap_handshake_attach_circuit().
unsigned int is_transparent_ap |
True iff this is an AP connection that came from a transparent or NATd connection
Definition at line 92 of file entry_connection_st.h.
const char* marked_pending_circ_file |
Definition at line 64 of file entry_connection_st.h.
uint16_t marked_pending_circ_line |
Definition at line 63 of file entry_connection_st.h.
unsigned int may_use_optimistic_data |
For AP connections only: Set if this connection's target exit node allows optimistic data (that is, data sent on this stream before the exit has sent a CONNECTED cell) and we have chosen to use it.
Definition at line 98 of file entry_connection_st.h.
Referenced by circuit_detach_stream(), and connection_ap_supports_optimistic_data().
unsigned int num_circuits_launched |
Number of times we've launched a circuit to handle this stream. If it gets too high, that could indicate an inconsistency between our "launch a circuit to handle this stream" logic and our "attach our stream to one of the available circuits" logic.
Definition at line 72 of file entry_connection_st.h.
uint8_t num_socks_retries |
Number of times we've reassigned this application connection to a new circuit. We keep track because the timeout is longer if we've already retried several times.
Definition at line 45 of file entry_connection_st.h.
Referenced by compute_retry_timeout().
unsigned nym_epoch |
AP only: The newnym epoch in which we created this connection.
Definition at line 33 of file entry_connection_st.h.
Referenced by entry_connection_describe_status_for_controller().
char* original_dest_address |
AP only: The original requested address before we rewrote it.

Referenced by connection_edge_compatible_with_circuit(), and connection_edge_update_circuit_isolation().
struct buf_t* pending_optimistic_data |
For AP connections only: buffer for data that we have sent optimistically, which we might need to re-send if we have to retry this connection.
Definition at line 50 of file entry_connection_st.h.
struct buf_t* sending_optimistic_data |
Definition at line 54 of file entry_connection_st.h.
socks_request_t* socks_request |
SOCKS structure describing request (AP only.)

unsigned int use_begindir |
True iff this stream should use a BEGIN_DIR relay command to establish itself rather than BEGIN (either via onehop or via a whole circuit).
