This is a brief system message to let you know about some upcoming changes to the $HOST service. Some of your contacts are on other Jabber/XMPP services that do not support encryption. As part of an initiative to increase the security of the Jabber/XMPP network, this service ($HOST) will be participating in a series of tests to discover the impact of our planned changes, and you may lose the ability to communicate with some of your contacts. The test days well be on the following dates: January 4, February 22, March 22 and April 19. On these days we will require that all client and server connections are encrypted. Unless they enable encryption before that, you will be unable to communicate with your contacts that use these services: $SERVICES Your affected contacts are: $CONTACTS What can you do? You may tell your contacts to inform their service administrator about their lack of encryption. Your contacts may also switch to a more secure service. A list of public services can be found at https://xmpp.net/directory.php For more information about the Jabber/XMPP security initiative that we are participating in, please read the announcement at https://stpeter.im/journal/1496.html If you have any questions or concerns, you may contact us via $CONTACTVIA at $CONTACT ]]; local message = module:get_option_string("manifesto_contact_encryption_warning", default_tpl); local contact = module:get_option_string("admin_contact_address", module:get_option_array("admins", {})[1]); if not contact then error("mod_manifesto needs you to set 'admin_contact_address' in your config file.", 0); end local contact_method = "Jabber/XMPP"; if select(2, contact:gsub("^mailto:", "")) > 0 then contact_method = "email"; end local notified; module:hook("resource-bind", function (event) local session = event.session; local now = time(); local last_notify = notified[session.username] or 0; if last_notify > ( now - 86400 * 7 ) then return end timer.add_task(15, function () local bad_contacts, bad_hosts = {}, {}; for contact_jid, item in pairs(session.roster or {}) do local _, contact_host = jid_split(contact_jid); local bad = false; local remote_host_session = host_session.s2sout[contact_host]; if remote_host_session and remote_host_session.type == "s2sout" then -- Only check remote hosts we have completed s2s connections to if not remote_host_session.secure then bad = true; end end for session in pairs(incoming_s2s) do if session.to_host == host and session.from_host == contact_host and session.type == "s2sin" then if not session.secure then bad = true; end end end if bad then local contact_name = item.name; if contact_name then table.insert(bad_contacts, contact_name.." <"..contact_jid..">"); else table.insert(bad_contacts, contact_jid); end if not bad_hosts[contact_host] then bad_hosts[contact_host] = true; table.insert(bad_hosts, contact_host); end end end if #bad_contacts > 0 then local vars = { HOST = host; CONTACTS = " "..table.concat(bad_contacts, "\n "); SERVICES = " "..table.concat(bad_hosts, "\n "); CONTACTVIA = contact_method, CONTACT = contact; }; session.send(st.message({ type = "headline", from = host }):tag("body"):text(message:gsub("$(%w+)", vars))); end notified[session.username] = now; end); end); function module.load() notified = dm.load(nil, host, module.name) or {}; end function module.save() dm.store(nil, host, module.name, notified); return { notified = notified }; end function module.restore(data) notified = data.notified; end function module.unload() dm.store(nil, host, module.name, notified); end function module.uninstall() dm.store(nil, host, module.name, nil); end
