OpenWebRTC on iOS can crash if given a TURN server that doesn't accept connections #375

Open dbkr opened 9 years ago

dbkr commented 9 years ago

Our demo had no Internet access and was over a direct network connection, so we were improvising by specifying a TURN URI pointing to a server that just had no TURN server running. The expectation here was that since the two devices could communicate directly they should never need to use the turn server. In practice, our iOS app crashed in the OpenWebRTC SDK with the following stack trace:

ara4n commented 9 years ago

The reason we were specifying a TURN server at all was because empirically OWR->FF37 calls (signalled via matrix) had ICE failures if there was no internet access, unless you specified a TURN server. (Even if that TURN server didn't exist).

I failed to realise that this could then cause Janus->OWR calls to crash - I guess we got sidetracked by the original bogus stacktrace.

superdump commented 9 years ago

The crash is somewhere in libnice: http://cgit.freedesktop.org/libnice/libnice/tree/agent/agent.c#n5992 I don't see why it would crash there though.
