1825826 - Allow media.peerconnection.ice.proxy_only to affect only PBM

Status: RESOLVED FIXED

(Core :: WebRTC: Networking, enhancement)

Description

[Tom Ritter [:tjr]]

We want to test enabling media.peerconnection.ice.proxy_only, but we want to restrict the behavior to PBM only. To accomplish this, I am envisioning adding a media.peerconnection.ice.proxy_only.pbmode pref that, if true, enables the behavior in PBM. If media.peerconnection.ice.proxy_only is enabled, that behavior is used in Normal and PBM regardless of the pbmode pref.

I tested this with https://ritter.vg/misc/ff/webrtc-ip2.html

I confirmed that after granting capture permissions, I could leak my internal IP addresses - both in regular and PBM, (I couldn't leak my local IP without granting capture permissions.) Then I enabled the (new) pref, confirmed it still leaked in regular, and that in PBM it did not.

In PBM, with the pref enabled, I got the error ICE failed, add a TURN server and see about:webrtc for more details if I enumerated before getting capture permissions; and no error if I tried to enumerate after granting capture permissions. In neither case did it give either my local or remote IP address.
