mod_c2s_conn_throttle: Reduce log level from error->info
Our general policy is that "error" should never be triggerable by remote
entities, and that it is always about something that requires admin
intervention. This satisfies neither condition.
The "warn" level can be used for unexpected events/behaviour triggered by
remote entities, and this could qualify. However I don't think failed auth
attempts are unexpected enough.
I selected "info" because it is what is also used for other notable session
lifecycle events.
local st = require "util.stanza";
local whitelist = module:get_option_inherited_set("s2s_whitelist", {});
module:hook("route/remote", function (event)
if not whitelist:contains(event.to_host) then
module:send(st.error_reply(event.stanza, "cancel", "not-allowed", "Communication with this domain is restricted"));
return true;
end
end, 100);
module:hook("s2s-stream-features", function (event)
if not whitelist:contains(event.origin.from_host) then
event.origin:close({
condition = "policy-violation";
text = "Communication with this domain is restricted";
});
end
end, 1000);
