mod_isolate_host: handle server-generated stanzas The hook for setting the no_host_isolation is only called for c2s sessions. This does not work for stanzas generated by the server, such as PEP notifications or presence probe answers. To handle that, we do per-stanza checks for the case that the origin is local.

Introduction
============

This module allows you to manually pin certificate fingerprints of
remote servers.

Details
=======

Servers not listed in the configuration are not affected.

Configuration
=============

After installing and enabling this module, you can put fingerprints of
remote servers in your config like this:

``` {.lua}
s2s_auth_fingerprint_digest = "sha1" -- This is the default. Other options are "sha256" and "sha512"
s2s_trusted_fingerprints = {
    ["jabber.org"] = "11:C2:3D:87:3F:95:F8:13:F8:CA:81:33:71:36:A7:00:E0:01:95:ED";
    ["matthewwild.co.uk"] = {
        "FD:7F:B2:B9:4C:C4:CB:E2:E7:48:FB:0D:98:11:C7:D8:4D:2A:62:AA";
        "CF:F3:EC:43:A9:D5:D1:4D:D4:57:09:55:52:BC:5D:73:06:1A:A1:A0";
    };
}

-- If you don't want to fall back to dialback, you can list the domains s2s_secure_domains too
s2s_secure_domains = {
    "jabber.org";
}
```
