**DoH Rollout** refers to the webextension code that decides whether TRR will

be enabled automatically for users in the `rollout population <https://support.mozilla.org/kb/firefox-dns-over-https#w_about-the-us-rollout-of-dns-over-https>`_.
|
||||
|
||||
The functioning of this module is described `here <https://wiki.mozilla.org/Security/DNS_Over_HTTPS>`_.
|
||||
|
||||
The code lives in `browser/components/doh <https://searchfox.org/mozilla-central/source/browser/components/doh>`_.
|
||||
|
||||
Implementation
|
||||
--------------
|
||||
|
||||
When enabled TRR may work in two modes, TRR-first (2) and TRR-only (3). These are controlled by the **network.trr.mode** or **doh-rollout.mode** prefs.
|
||||
The difference is that when a DoH request fails in TRR-first mode, we then fallback to **Do53**.
|
||||
|
||||
For TRR-first mode, we have a strict-fallback setting which can be enabled by setting network.trr.strict_native_fallback to true.
|
||||
With this, while we will still completely skip TRR for certain requests (like captive portal detection, bootstrapping the TRR provider, etc.)
|
||||
we will only fall back after a TRR failure to **Do53** for three possible reasons:
|
||||
1. We detected, via Confirmation, that TRR is currently out of service on the network. This could mean the provider is down or blocked.
|
||||
2. The address successfully resolved via TRR could not be connected to.
|
||||
3. TRR result is NXDOMAIN.
|
||||
|
||||
In other cases, instead of falling back, we will trigger a fresh Confirmation (which will start us on a fresh connection to the provider) and
|
||||
retry the lookup with TRR again. We only retry once.
|
||||
|
||||
DNS name resolutions are performed in nsHostResolver::ResolveHost. If a cached response for the request could not be found, nsHostResolver::NameLookup will trigger either
|
||||
a DoH or a Do53 request. First it checks the effective TRR mode of the request
|
||||
is as requests could have a different mode from the global one.
|
||||
|
|
@ -84,8 +72,6 @@ The confirmation state has one of the following values:
|
|||
|
||||
The state machine for the confirmation is defined in the `HandleConfirmationEvent` method in `TRRService.cpp`.
|
||||
|
||||
If strict fallback mode is enabled, Confirmation will set a flag to refresh our connection to the provider.
