1778510 - Cut Performance and timestamps in general over to fine-grained RFP checks

Status: RESOLVED FIXED

(Core :: DOM: Performance APIs, enhancement)

Description

[Tom Ritter [:tjr]]

I had thought this would be a simple patch, but as I got more and more into it I realized how expansive it was.

The goal, in general, is to cut over all ReduceTimePrecision* callsites over to a new signature that takes in a shouldResistFingerprinting boolean to allow fine-grained control of whether we should use RFP's timer precision, or Firefox's general timer precision.

This boolean will be provided by fine-grained calls based on the context of the call, using the newer fine-grained nsContentUtils::ShouldResistFingerprinting() functions.

Along the way we remove the calls to JS::SetTimeResolutionUsec.
This function is used to set values that are only used when
we don't have a ReuceTimerPrecision callback, which we always do
(as confirmed by coverage.) This in turns lets us remove some
other code.

The System Principal boolean was only used for RFP purposes.
We can repurpose the same boolean for our fine-grained RFP

but rather in the CreateFor methods that will populate it
based on the context of their construction.

This commit moves the test description from the test file

It also adds two parameters to the set of shared tests:
extraData and extraPrefs. extraData is data passed through
to the validation function (mostly) unchanged and unused.
extraPrefs are prefs that applied (and removed) before executing
the test.

Attachment: Bug 1778510: Add tests that exercise RFP exemptions r?timhuang

We now need to check if a value is rounded to the RFP
value (16.67ms) or the baseline RTP value (default 1 ms).
To do this we pass both precisions in extraData.

We also need to communicate the expected behavior of rounding,
that is if RFP should apply for this test set. Typically we
would know this based on the expectedValues which are supplied
to the testFunction (as in the navigator test) - but here we
don't know the expected values ahead of time - we're testing if
timer values are properly rounded. Therefore we need to add
a boolean (in each test) that indicates if RFP is expected to
apply for this test.

Comment 29

[Tom Ritter [:tjr]]

Welcome everyone to this very large patchset you have been flagged for review on. I appreciate your attention.

As mentioned in the first comment: this patchset grew and grew until it eventually came to encompass all calls to the ReduceTimePrecision set of functions which means it affects virtually every dom-exposed timestamp everywhere.

To start at the beginning. In Bug 1450398 we (that is to say I, voluneteering on behalf of Tor) are pursuing a goal of allowing Resist Fingerprinting (RFP, privacy.resistFingerprinting, Tor's pref) to be disabled on a per-site basis, while also allowing it to be restricted to PBM and to not affect Web Extensions. It's a slow migration, and all behind a testing preference privacy.resistFingerprinting.testGranularityMask, so nothing is directly affecting Tor or FF users who have enabled RFP today.

The starting point of this bug was to cut over the Performance objects so they didn't round the timestamp when they didn't need to. I quickly realized that actually I would need to cut over all the ReduceTimePrecision functions. Presently, they take two bools IsSystemPrincipal and CrossOriginIsolated that help them determine their behavior. As part of this cutover, these functions needed to now consider three bools: ShouldResistFingerprinting (because no longer is this a global pref, but now a context-sensitive decision where we pass in the appropriate behavior), IsSystemPrincipal, and CrossOriginIsolated. That's a lot of bools, so I opted to make it a bitfield.

I would also need to throw a ShouldRFP boolean into a JS Context, as JS will call into the ReduceTimePrecision functions also. This means Workers, Worklets, and the normal page JS Realm get some attention as well.

So the bulk of the patches for everyone besides Tim are of the form "Figure out if we should resist fingerprinting in this context by using the new ShouldRFP functions and then use a new helper function GetRTPCallerType() to call the ReduceTimePrecision function". You will probably want to peek at D156504 to see how that helper function works so you can be sure I'm doing the right thing in your particular area of expertise.

I have try nearly completely green, I'm just doing some double checking that these are true intermittents not related to the patch.

As far as testing goes, all tests that previously tested that timestamps are clamped appropriately should still pass. Even better if they tested Cross Origin Isolation or RFP. Tests that did RFP sometimes needed to be refactored, in particular this test which tests performance.now, event timestamp, JS' Date, audiocontext, and File's timestamp was completely rewritten to test things under third party iframes respecting RFP being exempted on different domains related to the frame/framer - so all that is pretty well tested.

Attachment: Bug 1778510: Move shouldRFP from WorkerPrivate to WorkerGlobalScopeBase r?asuth

This does not remove mShouldResistFingerprinting from
WorkerPrivate->mLoadInfo. This is because in between
mLoadInfo getting initialized (including where shouldRFP gets
set) and when the worker's global scope is constructed, we
need to keep track of whether we shouldRFP or not. We could
make this single bool an outparam of GetLoadInfo to later
pass to GetOrCreateGlobalScope, but that seems noisy.

[Tom Ritter [:tjr]]

Attachment: Bug 1778510: Will not land - Worker Fix r?asuth

I'm not going to land this patch, instead I'm going
to rebase it into the others like it was always this
way. But I wanted to get your r+ on it this way because
I thought that'd be easier to understand.

tl;dr: RTPCallerType on Workers (and probably Worklets)
was broken because they were off main thread.

Basically I was getting test failures that were not directly
attributed to this, but rather exposed the fact that RTPCaller
type wasn't working in workers. I eventually (took a looooong
time) realized that was because nsIGlobalObject::RTPCallerType
was using PrincipalOrNull() and if you're off main thread -
that's null.

So I let RTPCallerType be overrideen in subclasses, and override
it for Workers and Worklets. I tried to not duplicate code with
a second function, but it couldn't be used for Workers.
