- general construct/destroy in connectdata - default implementations of callback functions - connect: cfilters for connect and accept - socks: cfilter for socks proxying - http_proxy: cfilter for http proxy tunneling - vtls: cfilters for primary and proxy ssl - change in general handling of data/conn - Curl_cfilter_setup() sets up filter chain based on data settings, if none are installed by the protocol handler setup - Curl_cfilter_connect() boot straps filters into `connected` status, used by handlers and multi to reach further stages - Curl_cfilter_is_connected() to check if a conn is connected, e.g. all filters have done their work - Curl_cfilter_get_select_socks() gets the sockets and READ/WRITE indicators for multi select to work - Curl_cfilter_data_pending() asks filters if the have incoming data pending for recv - Curl_cfilter_recv()/Curl_cfilter_send are the general callbacks installed in conn->recv/conn->send for io handling - Curl_cfilter_attach_data()/Curl_cfilter_detach_data() inform filters and addition/removal of a `data` from their connection - adding vtl functions to prevent use of Curl_ssl globals directly in other parts of the code.
