These days, STUN/TURN authentication can be performed with ephemeral
credentials, where the REALM is irrelevant. Therefore, just log an
[info] message rather than a [warning] in the case where no
authentication REALM is configured but multiple virtual domains exist.
Add the 'mod_stun_disco' module, which allows XMPP clients to discover
STUN/TURN services and to obtain temporary credentials for using them as
per XEP-0215: External Service Discovery. The temporary credentials
handed out to clients have the format described in:
https://tools.ietf.org/html/draft-uberti-behave-turn-rest-00
Also add the new module to the example configuration file.
Closes#2947.
We really don't need those, and thanks to each individual room having
different hash (as one of hashed data is room description) we end with
lot of data that we really don't need.
Make sure modules won't be reloaded before listeners. This is necessary
to allow the (not yet committed) 'mod_stun_disco' module to parse the
listener configuration after configuration reloads.
The 'turn_ip' option validator doesn't accept an inet:ip4_address()
tuple.
While at it, change the logic to only perform the fallback address
lookup if no 'turn_ip' is configured (analogous to the fallback
mechanism for the case where the 'auth_realm' is undefined).
Try to resolve the local hostname, use the result as the default
'turn_ip', and only log a warning if that fails. Using the local
hostname's address by default is analogous to mod_proxy65's behavior.
When another connection is inserting something to spool at this same time
as we do pop_messages, it's possible that insert will happen between we
fetch messages and delete them, so we effectively will delete it without
delivering it to client. This change catch this situation and restart
transaction, so we should always have consistent results.
It looks like old version of Smack don't accept request that are have
from sent to sender jid, but are only working when jid is set to server
address. This is also how it looks in old xmpp rfc examples.
Messages that are received when no c2s is active will be stored in offline,
even when mam archived them, so i don't think we should be doing something
different in this case.
