mod_compat_dialback

This module provides a workaround for servers that do not set the to attribute on stream headers, which is required per RFC6120:

4.7.2. to

For initial stream headers in both client-to-server and server-to-server communication, the initiating entity MUST include the ‘to’ attribute and MUST set its value to a domainpart that the initiating entity knows or expects the receiving entity to service.

As a side effect of this issue, Prosody 0.10 will be unable to do Dialback with servers that don’t follow this.

Known servers affected

• Openfire 3.10.2 (and probably earlier versions)

sudo prosodyctl install --server=https://modules.prosody.im/rocks/ mod_compat_dialback
