1592620 - Add whitelist for mDNS hostname obfuscation

Status: VERIFIED FIXED

(Core :: WebRTC: Networking, enhancement, P2)

Description

[Dan Minor [:dminor]]

Usecase from drno: The Chrome folks announced that they are going to put a enterprise policy around mDNS. The idea is that enterprise network can provision a white list of domains for which the browser disables the mDNS feature. I was approached last week if we could launch with the same thing. The use case: apparently are company internal all hands streaming, where people are just watching, so recvonly. Which triggers mDNS, because the consumers don't turn on their mic/cam. And because of mDNS not working in their big enterprise networks they can't share the all hands video feed among the browsers any more.

Attachment: Bug 1592620 - Add whitelist for mDNS hostname obfuscation; r=bwc!

This adds a whitelist of domains for which mDNS hostname obfuscation is
disabled. The implementation is an updated version of the old screensharing
whitelist code.

I'm adding a pref policy in 1588183

once Chrome has a name for the official policy, I'll add that as well.
