Summary:
This patch restricts any calls to navigator.credentials.* methods to selected
tabs. Any active WebAuthn request will be aborted when the parent chrome
window loses focus, or the <browser> is backgrounded.

Summary:
Always replace attestation statements with a "none" attestation.
Bug 1430150 will introduce a prompt that asks the user for permission whenever
the RP requests "direct" attestation. Only if the user opts in we will forward
the attestation statement with the token's certificate and signature.

The Web Authentication CollectedClientData is missing the type field, which
is just a simple string. (The editor's draft also removes hashAlgorithm, but
let's not get ahead of ourselves...)
Add in that simple string. This was found at interop testing.

The WebAuthn spec lets RPs ask to specifically get direct attestation certificates
during credential creation using the "Attestation Conveyance Preference" [1].
This change adds that field into the WebIDL and ignores it for now. This is
pre-work to Bug #1430150 which will make this useful (which in turn requires
Bug #1416056's support for anonymizing those attestation certificates).

Summary:
Add support for PublicKeyCredentialRequestOptions.userVerification. For now
this basically means that we'll abort the operation with NotAllowed, as we
don't support user verification yet.
Pass PublicKeyCredentialDescriptor.transports through to the token manager
implementations. The softoken will ignore those and pretend to support all
transports defined by the spec. The USB HID token will check for the "usb"
transport and either ignore credentials accordingly, or abort the operation.
Note: The `UserVerificationRequirement` in WebIDL is defined at https://w3c.github.io/webauthn/#assertion-options

webauthn says[1] that public keys are encoded as COSE keys. I find the COSE
RFC quite circuitous in many respects and so any reviews should check whether
they agree with my understanding of what should be in a COSE key.
The webauthn spec says that the key:
“MUST contain the "alg" parameter and MUST NOT contain
any other optional parameters.”
I don't believe that any of the parameters included are optional but, again, I
don't think the RFC is completely clear.

Summary:
We currently implement no platform authenticators, so this would always
resolve to false. For those cases, the spec recommends a resolve timeout
on the order of 10 minutes to avoid fingerprinting.
A simple solution is thus to never resolve the promise, otherwise we'd
have to track every single call to this method along with a promise
and timer to resolve it after exactly X minutes.
A Relying Party has to deal with a non-response in a timely fashion, so
we can keep this as-is (and not resolve) even when we support platform
authenticators but they're not available, or a user rejects a website's
request to use them.

The WD-06 (and later) WebAuthn specs choose to move to integer algorithm
identifiers for the signatures [1], with a handful of algorithms identified [2].
U2F devices only support ES256 (e.g., COSE ID "-7"), so that's all that is
implemented here.
Note that the spec also now requires that we accept empty lists of parameters,
and in that case, the RP says they aren't picky, so this changes what happens
when the parameter list is empty (but still aborts when the list is non-empty
but doesn't have anything we can use) [3].
There's a follow-on to move parameter-validation logic into the U2FTokenManager
in Bug 1409220.

It adds the method isPlatformAuthenticatorAvailable which is incomplete and

Adds type PublicKeyCredentialRpEntity.
Adds "userId" to AuthenticatorAssertionResponse.
Adds "id" as a buffer source to PublicKeyCredentialUserEntity and as a
DOMString to PublicKeyCredentialRpEntity, refactoring out the "id" field
from the parent PublicKeyCredentialEntity.
It also adds a simple enforcement per spec 4.4.3 "User Account Parameters for
Credential Generation" that the new user ID buffer, if set, be no more than
64 bytes long. I mostly added it here so I could adjust the tests all at once
in this commit.

WebAuthn has added a flag UV to indicate the user was biometrically verified. We
have to make sure not to set that flag for U2F. Turns out we already do that,

There's an intermittent which might be spurious because ASN.1 signatures might
sometimes be less than 70 bytes, but the actual floor is probably 68 (32 + 32
+ 4).
It's a sanity check, so I've adjusted it down and also am now emitting the
offending key bytes if this triggers again.

The Web Authentication types, by spec, return ArrayBuffer objects, while we
were returning a concrete Uint8Array. This is a fairly straightforward change
to add functionality to CryptoBuffer and the WebIDL types, however it's a
substantial change to the tests.
Frankly, the tests just could use another pass of clean-up now, since this is
a lot of relative ugliness added in. I refactored tab_webauthn_success.html
pretty heavily -- since it was also fairly ugly to start -- but I decided to go
with a lighter touch on the other tests.

Now that there are actual hardware devices, this test can't be run: it
depended on there being a deliberately-erroring implementation of WebAuthn
which would instantly reject promises. Fortunately, this test was really more
a test that telemetry scalars work properly than really the functionality
of WebAuthn.
Sadly, I don't see any way to re-enable this test without adding a new test-
only pref to the tree, which doesn't seem worth it for the telemetry.
So this patch removes the offending test completely which was backed out in
https://hg.mozilla.org/integration/mozilla-inbound/rev/c115eec567a6 .

In Bug 1380421 we reverted some behavior that required Web Authentication's
RP ID to be domain string to permit it to be an origin, too, for interop
testing. That is no longer needed, so this patch resumes enforcement that
RP ID be a domain string.
It also adds a needed test that the RP ID hash is calculated correctly.

WD-05 changed the "hashAlg" parameter of the CollectedClientData definition
from using an internally-defined "S256" string to identify the sha256 digest
to the definition in WebCrypto [1]. This only appears once, hard-coded in
WebAuthn (since U2F only supports SHA-256), so we need to change that one
instance.

This patch intends to obtain a 1) rough sense of the percentage of telemetry
population using Web Authentication over time, and 2) whether or not the
Authentication request was successful or errored out as a scalar. It also tracks
3) how long it takes for requests to complete as a histogram.
It counts Register (enrollment) and Sign (login) separately as we would
anticipate there being far, far more Sign uses than Register.

The WebAuthn WD-05 version of the specification defines the Origin field [1]
of the CollectedClientData as being set to the RP ID [2][3].
Note there is some ambiguity in the specification, as [1] says
CollectedClientData.Origin is the document's origin, while the
algorithms [2] and [3] set it to RP ID.
I'm going to stick with the algorithm's definition for this patch; it's
simple to revert when we move to WD-06 (Bug 1384776).

The Web Authentication PublicKeyCredential object has two fields currently
unpopulated which, to be spec-compliant, must be set. These fields duplicate
available data.
[PublicKeyCredential.id] must be set to the base64url encoding with omitted
padding of whatever data is in "rawId".
[PublicKeyCredential.type] must be the literal "public-key".

Web Authentication uses JWK algorithm names (ES256) instead of WebCrypto names
(such as P-256). There are other JWK algorithm names, but our current U2F-backed
implementation only can support ES256 anyway, as that's all that FIDO U2F
devices understand. This patch limits us to the name ES256 for the "alg"
parameter.
