1657808 - Restrict DTLS 1.3 to Nightly and keep DTLS 1.0 in Release

Status: RESOLVED FIXED

(Core :: WebRTC: Networking, defect, P1)

Description

[Nils Ohlmeier [:drno]]

The patch in bug 1641308 accidentally lets DTLS 1.3 ride the trains to release. Additionally it seems like Chrome is unfortunately still not ready to remove DTLS 1.0 yet, so we want to wait with the removal of that.

[Nils Ohlmeier [:drno]]

[Tracking Requested - why for this release]: The change to remove DTLS 1.0 was intended to ride the trains in 80 as it would have aligned with Chrome doing the same thing. But as the removal is not yet ready on the Chrome side we should wait as well. Additionally the patch in bug 1641308 accidentally turns on DTLS 1.3 for all trains.

Beta/Release Uplift Approval Request

• User impact if declined: Firefox users might face connection problems with WebRTC services which still rely on the old DTLS 1.0 version. And Firefox users might encounter new connectivity problems because the not yet fully specified and tested DTLS 1.3 version accidentally got turned on by default in a previous patch.
• Is this code covered by automated tests?: Yes
• Has the fix been verified in Nightly?: No
• Needs manual test from QE?: No
• If yes, steps to reproduce:
• List of other uplifts needed: None
• Risk to taking this patch: Low
• Why is the change risky/not risky? (and alternatives if risky): It is changing prefs which we have change several times before and know are working as expected.
• String changes made/needed: N/A
