| void tcp_connection_cleanup | ( | tcp_connection_t * | tc | ) |
| void tcp_connection_close | ( | tcp_connection_t * | tc | ) |
Begin connection closing procedure.
If at the end the connection is not in CLOSED state, it is not removed. Instead, we rely on on TCP to advance through state machine to either 1) LAST_ACK (passive close) whereby when the last ACK is received tcp_connection_del is called. This notifies session of the delete and calls cleanup. 2) TIME_WAIT (active close) whereby after 2MSL the 2MSL timer triggers and cleanup is called.
N.B. Half-close connections are not supported
Definition at line 385 of file tcp.c.
Here is the call graph for this function: Here is the caller graph for this function:| void tcp_connection_del | ( | tcp_connection_t * | tc | ) |
Connection removal.
This should be called only once connection enters CLOSED state. Note that it notifies the session of the removal event, so if the goal is to just remove the connection, call tcp_connection_cleanup instead.
