Description of problem: When connecting over proxy to IPv6 host, proxy returns 400 Bad Request because spice-gtk sends the address in the request without the enclosing brackets, e.g.: CONNECT 1234::1122:33ff:fe44:5566:5900 HTTP/1.0 instead of correct: CONNECT [1234::1122:33ff:fe44:5566]:5900 HTTP/1.0 Version-Release number of selected component (if applicable): spice-gtk3-0.26-8.el7.x86_64 glib-networking-2.42.0-1.el7.x86_64 glib2-2.46.2-3.el7.x86_64 How reproducible: always Steps to Reproduce: 1. run SPICE_PROXY=http://proxy.example.com remote-viewer spice://[ipv6]:port (ipv6 nor any VM has to be active, error takes place before proxy trying to connect to it) 2. 3. Actual results: 400 Bad Request Expected results: successful connection or different error Additional info:
Maybe a bug in proxy_lookup_ready() in spice-session.c, but this probably means spice_uri_create() (which returns a string of the form "spice://$host:$port") has the same issue. Or a bug in wocky-http-proxy.c:create_request(), which could try to use g_inet_address_new_from_string () on g_proxy_address_get_destination_hostname() to make sure it's not an ipv6 address it needs to bracket.
As Christophe said, the problem was missing "[]" around the hostname Fix was pushed upstream: ea37f06eaa11b6307c797895aeb85d87d142625a
