How can I "interconnect" two sockets in Linux?
- by Vi
There are two connected sockets. How can I interconnect them?
Data appeared on the one socket should be written to the other.
EOF/FIN should propogate well. If one is half-closed, the other should also be half-closed.
int client = get_connected_client_socket();
int proxy = get_connected_proxy_socket();
negotiate_with_proxy(proxy);
iterconnect(client, proxy);
// Now forgot about both client and proxy.
// System should handle IO/shutdown/close.
// Ideally even without any support of the user-space process.
Can Linux do it? Can it be done by tricking connection tracking to change tracking status of existing connection?
