How can I get the local address in sf_connect_out_func or is there another way to achieve this?

Have you tried calling `sock_getsockname`? If anything is going to work, that’d be it.

Yes. If I call `sock_getsockname` in `sf_connect_out_func`, an empty address will be returned. I think it is still in the early stage of a connection, there is no local address allocated. One more thing I found, I can get local address by `sock_getsockname` in `sf_notify_fn` for some event. BUT, in `sf_notify_fn` I cannot filter the trafiic since it is a void function.
