Macros
States of OR connections
These must be in a partial ordering such that usually no OR connection will transition from a higher-numbered state to a lower-numbered one. Code such as bto_update_best() depends on this ordering to determine the best state it's seen so far.

Macro Definition Documentation

OR_CONN_STATE_CONNECTING

#define OR_CONN_STATE_CONNECTING   1

State for a connection to an OR: waiting for connect() to finish.

Definition at line 31 of file orconn_event.h.

OR_CONN_STATE_OPEN

#define OR_CONN_STATE_OPEN   8

State for an OR connection: Ready to send/receive cells.

Definition at line 53 of file orconn_event.h.

OR_CONN_STATE_OR_HANDSHAKING_V2

#define OR_CONN_STATE_OR_HANDSHAKING_V2   6

State for an OR connection: We're done with our SSL handshake, we've done renegotiation, but we haven't yet negotiated link protocol versions and sent a netinfo cell.

Definition at line 47 of file orconn_event.h.

OR_CONN_STATE_OR_HANDSHAKING_V3

#define OR_CONN_STATE_OR_HANDSHAKING_V3   7

State for an OR connection: We're done with our SSL handshake, but we haven't yet negotiated link protocol versions, done a V3 handshake, and sent a netinfo cell.

Definition at line 51 of file orconn_event.h.

OR_CONN_STATE_PROXY_HANDSHAKING

#define OR_CONN_STATE_PROXY_HANDSHAKING   2

State for a connection to an OR: waiting for proxy handshake to complete

Definition at line 33 of file orconn_event.h.

OR_CONN_STATE_TLS_CLIENT_RENEGOTIATING

#define OR_CONN_STATE_TLS_CLIENT_RENEGOTIATING   4

State for a connection to an OR: We're doing a second SSL handshake for renegotiation purposes. (V2 handshake only.)

Definition at line 39 of file orconn_event.h.

OR_CONN_STATE_TLS_HANDSHAKING

#define OR_CONN_STATE_TLS_HANDSHAKING   3

State for an OR connection client: SSL is handshaking, not done yet.

Definition at line 36 of file orconn_event.h.

OR_CONN_STATE_TLS_SERVER_RENEGOTIATING

#define OR_CONN_STATE_TLS_SERVER_RENEGOTIATING   5

State for a connection at an OR: We're waiting for the client to renegotiate (to indicate a v2 handshake) or send a versions cell (to indicate a v3 handshake)

Definition at line 43 of file orconn_event.h.

Enumeration Type Documentation
