    For diebesban.de issue - this should already be handled in 8.1.0 as there is an exception for features (https://github.com/tigase/tigase-server/blob/old-stable/src/main/java/tigase/server/xmppserver/proc/PacketChecker.java#L119)

    Looking at the code (https://github.com/tigase/tigase-server/blob/7c1a51d95e001a5da31318ff67ce8ba3121b027c/src/main/java/tigase/server/xmppserver/proc/PacketChecker.java#L119) I'm wondering whether we should add exceptions for <challenge xmlns="urn:ietf:params:xml:ns:xmpp-sasl">=</challenge> (though, it happens on tigase.im, which doesn't have above fix yet so maybe it doesn't matter) - what you think @andrzej.wojcik ?

  • Andrzej Wójcik (Tigase) commented 5 years ago

    AFAIR, this only happens if the stanza is not process by any S2S processor. In case of <challenge/> it should be processed, so there should not be any issues. As for <features/> if they were empty, they were not processed by any S2S processor and that was causing the issue.

  • Wojciech Kapcia (Tigase) commented 5 years ago

    OK, thank you for the explanation. It was said that it's possible to connect to tigase.org, so most likely the issue was fixed in 8.1.0.
