mod_smacks: Bounce unhandled stanzas from local origin (fix #1759)
Sending stanzas with a remote session as origin when the stanzas have a
local JID in the from attribute trips validation in core.stanza_router,
leading to warnings:
> Received a stanza claiming to be from remote.example, over a stream authed for localhost.example
Using module:send() uses the local host as origin, which is fine here.
local st = require "util.stanza";
local xmlns_csi = "urn:xmpp:csi:0";
local csi_feature = st.stanza("csi", { xmlns = xmlns_csi });
local csi_handler_available = nil;
module:hook("stream-features", function (event)
if event.origin.username and csi_handler_available then
event.features:add_child(csi_feature);
end
end);
function refire_event(name)
return function (event)
if event.origin.username then
event.origin.state = event.stanza.name;
module:fire_event(name, event);
return true;
end
end;
end
module:hook("stanza/"..xmlns_csi..":active", refire_event("csi-client-active"));
module:hook("stanza/"..xmlns_csi..":inactive", refire_event("csi-client-inactive"));
function module.load()
if prosody.hosts[module.host].events._handlers["csi-client-active"] then
csi_handler_available = true;
module:set_status("core", "CSI handler module loaded");
else
csi_handler_available = false;
module:set_status("warn", "No CSI handler module loaded");
end
end
module:hook("module-loaded", module.load);
module:hook("module-unloaded", module.load);
