1042345 - Problems with DNS resolution for ice configuration on B2G

Status: RESOLVED DUPLICATE of bug 1042873

(Core :: WebRTC, defect)

Description

[Nils Ohlmeier [:drno]]

B2G does not support STUN servers with DNS names, but only with IP addresses.

[Blocking Requested - why for this release]:

Nominating to 2.0, as without this fix, Loop FxOS calls are not going to work when located in different networks.

Comment 2

[Nils Ohlmeier [:drno]]

Sorry misunderstood how nICEr is doing DNS resolution.

Comment 3

[Jason Smith [:jsmith]]

Shell - Can you find out if this can be worked around on the server-side with Tokbox?

Comment 4

[Maire Reavy [:mreavy]]

It can.  I've asked TokBox to make that change ASAP.  They are preparing a change -- first to their QA system to verify it fixes this issue.

Comment 5

[Eric Rescorla (:ekr)]

As Byron indicates, this is not a lack of DNS resolution but most likely instead
a byte ordering issue in the resolution system:

ICE(PC:272899921727 (id=4 url=http://mozilla.github.io/webrtc-landing/stun_test.html)): resolved candidate srflx(IP4:31.133.149.56:45999/UDP|stun.l.google.com:19302). addr=IP4:173.194.78.127:26187/UDP

Okay. Thanks for the clarification.

Maria - Given that this can fixed via a server-side workaround for Loop, are you okay with triage deciding to unblock this?

[Eric Rescorla (:ekr)]

Byron has found the problem. I suggest we just wait instead of doing a workaround.

Okay - blocking on this basis then. We'll fix this directly in the platform. If there's concern with this, feel free to renominate.
