MongooseIM 2.2 - The Global Server

Authentication with certificates

Typical XMPP authentication involves a password or a token that is sent to the server. There are several SASL (Simple Authentication and Security Layer) mechanisms with SCRAM-SHA-1 being the recommended one.

Stable Global Distribution

All of you know what mobile network and landline are. The former allows you to call everyone in the world, as long as they carry their device with them, always with the same number. The latter requires the recipient to be present at a specific location in order to receive a call. What is more, you actually have to know where they are, as landline phone numbers (at least usually) include prefixes assigned to certain districts or cities.

Jingle/SIP proxy

Many VoIP applications rely on SIP — a protocol with good support and wide range of software implementing it. It has its shortcomings though. First of all, it is difficult to extend and is focused on P2P session management. Secondly, it does not use long-lived sessions.

Important security fix for error routing

This patch deserves a separate section as it is especially important for deployments based on previous MongooseIM versions that use the mod_event_pusher_push extension. A malicious user may send a prepared stanza that eventually could lead to an endless routing loop that crashes the MongooseIM node due to the out of memory exception.

Misc. technical improvements & changes

It’s always cool to have a strong highlights in a release but much more always happens behind the scenes. MongooseIM 2.2 includes many smaller changes or the ones relevant to developers rather than users and devops.

Header files refactoring

MongooseIM header files underwent significant refactoring, including split into smaller files and moving definitions to more appropriate places. Here are some examples: ejabberd.hrl has been renamed to mongoose.hrl All error macros from jlib.hrl have been transformed into mongoose_xmpp_errors.erl module. All namespace definitions from jlib.hrl have been moved to mongoose_ns.hrl JID-related type definitions have been moved to jid.erl

Mongoose Services

Classic MongooseIM extension modules are started for every served XMPP domain, as configured in a hosts option in a config file. In most cases it is a perfectly valid approach, e.g. in case of roster or privacy lists support. It does not apply though to features that should be started only once, e.g. Global Distribution (because it strictly operates only with two domains: global and local one) or mod_admin_extra.

Hidden components

Sometimes XMPP components connected to the server do not interact directly with ordinary clients but they are listed in Service Discovery result anyway. It is inconvenient if the deployment uses many of them and the Disco response to a client is not only big but simply cluttered.
