Configuration file
|
|
==================
|
|
|
|
[X] Global logging
|
|
[X] Modules
|
|
[X] Module directory
|
|
[X] Modules to load on startup
|
|
[X] Interface
|
|
[X] IP
|
|
[X] Port
|
|
[X] Domain
|
|
[-] Certificate file
|
|
[-] Key file
|
|
[X] Logging
|
|
[X] Log destination: syslog, file
|
|
[X] Log options: connection events, etc.
|

|
Code flow
|
|
=========
|
|
|
|
[X] Command line processing (Command line option can override the place of the
|
|
configuration file)
|
|
[X] Configuration file processing (Command line options override configuration
|
|
global values like modules directory, log destination)
|
|
[ ] Create logger thread
|
|
[ ] Start logging according to configuration
|
|
[ ] Load modules
|
|
[ ] Load module file
|
|
[ ] Run initialization function to...
|
|
[ ] Register extensions
|
|
[ ] Create special interfaces
|
|
[ ] Register to hooks
|
|
[ ] Create interfaces
|
|
[ ] Create listener thread and sockets
|
|
[ ] Create stream processing threads
|
|
[ ] Associate stream processing threads with sockets
|
|
[ ] Assign extensions to stream processing threads
|
|
[ ] Process extension configuration directives
|
|
[ ] Start socket thread
|
|
When new connection arrives
|
|
[ ] Create peer object
|
|
[ ] Associate with corresponding stream interface
|
|
[ ] Run main loop
|
|
[ ] Socket thread
|
|
[ ] New connections
|
|
[ ] Run "before-accept" hook
|
|
[ ] Create client object unless connection is dropped in
|
|
"before-accept"
|
|
[ ] Run "after-accept" hooks
|
|
[ ] Install "always-install" extensions on client
|
|
[ ] Wait for remote XML Stream to start
|
|
[ ] Assign client to correct interface
|
|
[ ] Old connections
|
|
[ ] Run "layer-accept" hooks
|
|
[ ] Run "before-interface" hooks
|
|
[ ] Pass to assigned interface
|
|
[ ] Run "after-interface" hooks
|
|
[ ] Logging thread
|
|
[ ] Process received lines one by one. Errors first, info next, debug
|
|
last
|
|
[ ] Interface threads
|
|
[ ] Receive data from socket thread
|
|
[ ] Run "before-process" hooks
|
|
[ ] Process stream
|
|
[ ] Run "after-process" hooks
|
|
[ ] Run "before-send" hooks
|
|
[ ] Send packet to destination if packet is finished
|
|
[ ] Run "after-send" hooks
|
|
|
|
During the connection additional extensions can be installed on the client,
|
|
like the layer-tls module's TLS encryptions extension.
|
|
|
|
Authentication
|
|
==============
|
|
|
|
When a client requests authentication, client credentials get through the
|
|
authentication module(s) associated with the interface. This authentication
|
|
module must always check the jid via an user storage module, and if necessary,
|
|
it should get the password (or any other credentials like a X509 certificate's
|
|
Common Name field, or a Kerberos principal name) from this storage module,
|
|
either.
|
|
|
|
Additional modules to provide
|
|
=============================
|
|
[ ] user-mysql
|
|
[ ] roster-mysql
|
|
[ ] user-postgresql
|
|
[ ] roster-postgresql
|
|
[ ] user-ldap
|
|
[ ] roster-ldap?
|
|
[ ] auth-cyrus-sasl
|
|
[ ] log-c2c
|
|
[ ] conn-blackwhite-list
|
|
|
|
