mod_muc_limits: Add config option to limit to join stanzas only
This is a bit more limited in pre-0.11 MUC modules, because it just
detects stanzas sent to full JIDs (which would include all presence
and nick changes).
This option is useful for setups where users are typically unaffiliated,
but trusted (e.g. if access to the room is gated through some other
means such as password/token auth).

16 First, download and add the module to `module_enabled`. Then you can |
| 1842 | 17 decide on what policy you want to have. |
| 18 | |
| 19 Requiring ciphers with forward secrecy is the most simple to set up. | |
| 20 | |
| 21 ``` lua | |
| 22 tls_policy = "FS" -- allow only ciphers that enable forward secrecy | |
| 23 ``` | |
| 24 | |
| 25 A more complicated example: | |
| 26 | |
| 27 ``` lua | |
| 28 tls_policy = { | |
| 29 c2s = { | |
| 30 encryption = "AES"; -- Require AES (or AESGCM) encryption | |
| 31 protocol = "TLSv1.2"; -- and TLSv1.2 | |
| 32 bits = 128; -- and at least 128 bits (FIXME: remember what this meant) | |
| 33 } | |
| 34 s2s = { | |
| 35 cipher = "AESGCM"; -- Require AESGCM ciphers | |
| 36 protocol = "TLSv1.[12]"; -- and TLSv1.1 or 1.2 | |
| 37 authentication = "RSA"; -- with RSA authentication | |
| 38 }; | |
| 39 } | |
| 40 ``` | |
| 41 | |
| 42 # Compatibility | |
| 43 | |
| 44 Requires LuaSec 0.5 | |
