In this case, should we set the ID on the request to be the ID of the current document? If we're trying to make the ID non-optional, I do think it's beneficial to have it populated with the "right" value for consistency, in places where we can predict what that value is.

Maybe add a comment here that we'll clean up this function eventually, unlike the other two.

Not blocking for this CL, but now that this is not optional, we should consider moving this higher up in the arguments list given its importance (I got this feedback on one of my Websocket/Webtransport CLs this week.)

File services/network/websocket_factory_unittest.cc
Line 243, Patchset 18 (Latest):TEST_F(WebSocketFactoryTest, CreateWebSocketBypassWithNoOpRestrictionsID) {

Do we need these tests? Seems a little out of place to test the NoOp ID just in this one spot.

    Xiaochen Zhou . resolved

    Non-blocking comment: In IsNetworkForNetworkRestrictionsIdAndUrlAllowed, perhaps consider early return if the the id == GetNoOpNetworkRestrictionsId(), so we can avoid a map lookup.

    File services/network/public/cpp/constants.h
    Line 24, Patchset 18 (Latest):const base::UnguessableToken& GetNoOpNetworkRestrictionsId();
    Xiaochen Zhou . unresolved

    We would like to require developers to choose one of the followings for network restriction id param:

    • The context's ID.
    • Or use one of the 3 functions here.

    But passing a `base::UnguessableToken::Null()` or `base::UnguessableToken{}` still compiles. Developers not aware of CA perhaps think this is reasonable.

    Perhaps we can have a wrapper class around base::UnguessableToken that disables the default constructor (marking it private). And it offers factory methods like these 3 and force developer to choose one.

    A lot more work is required though for adding the wrapper class.

        Thanks, content/ LGTM with a few notes.

        It seems that this is included and used in both the browser process code and network service process code. Does that mean that the browser process and NS process will have differing values for network::GetNoOpNetworkRestrictionsId(), etc, since we will create a unique token in each process? Is that ok?

        Would this also need to be updated to remove the optional at some point?

        General note: it's invalid to send an empty UnguessableToken over Mojo - [see here](https://source.chromium.org/chromium/chromium/src/+/main:base/unguessable_token.h;l=47-50;drc=cdc524b176956e1aa3d4bb4e3b4d7b156b6cbaa9). I wonder if that can cause any issues if this is read for an initial empty document of a brand new tab, or something where we don't otherwise create or inherit the network restrictions ID. I guess that document is unlikely to be scripted by another frame to do a network request that would need this, but it could potentially happen in a corner case via extension content scripts or DevTools.

        So I wonder if it should be invalid to return a null token here.

          That's a great point.
          The Test and TODO constants are ok to be in both processes with different values.

          The NoOp constant should only be necessary for populating the id in the browser process and network service should be agnostic to the value. If we tried to do early return based on NoOp before checking the network_restriction_ids_ map in the n/w service then it wouldn't really be working on the right NoOp value and other than that there is no use for it in the n/w service. Moving it to the content/browser layer makes sense but some of the layers like device/ cannot depend on content/ so instead I am adding a dcheck for it to only be invoked in the browser process.

          Thanks! I was adding the changes to always have this be initialized to no-op id in the follow up CL, but actually moving these changes here so this CL is safe. Also added DCHECKs for id to be non-empty before the network context mojo calls are called.

              Yes I am thinking that TODO will be removed soon after CA impl completion so doesn't really need to be in the doc.

              It seems that this is included and used in both the browser process code and network service process code. Does that mean that the browser process and NS process will have differing values for network::GetNoOpNetworkRestrictionsId(), etc, since we will create a unique token in each process? Is that ok?

              Shivani Sharma

              That's a great point.
              The Test and TODO constants are ok to be in both processes with different values.

              The NoOp constant should only be necessary for populating the id in the browser process and network service should be agnostic to the value. If we tried to do early return based on NoOp before checking the network_restriction_ids_ map in the n/w service then it wouldn't really be working on the right NoOp value and other than that there is no use for it in the n/w service. Moving it to the content/browser layer makes sense but some of the layers like device/ cannot depend on content/ so instead I am adding a dcheck for it to only be invoked in the browser process.

              Alex Moshchuk

              Ack. I'm not sure if there's a better way to check for the browser process from the network service code (I suppose we can't access switches::kProcessType :/); I'll leave that part to network service reviewers.

              I noticed that this will probably come up for Xiaochen's suggestion in https://chromium-review.git.corp.google.com/c/chromium/src/+/7899247/comment/a32c8401_91fbd03f/ to return early for NoOp case. I agree that a cleaner way forward would be with some sort of wrapper or union type (as crbug.com/520464337 suggests), where the bypass_allowlist case is more explicit, or sending the NoOp token to the network service if it needs to be in sync there.

              Line 130, Patchset 22: return base::UnguessableToken::Null();
              Alex Moshchuk . resolved

              General note: it's invalid to send an empty UnguessableToken over Mojo - [see here](https://source.chromium.org/chromium/chromium/src/+/main:base/unguessable_token.h;l=47-50;drc=cdc524b176956e1aa3d4bb4e3b4d7b156b6cbaa9). I wonder if that can cause any issues if this is read for an initial empty document of a brand new tab, or something where we don't otherwise create or inherit the network restrictions ID. I guess that document is unlikely to be scripted by another frame to do a network request that would need this, but it could potentially happen in a corner case via extension content scripts or DevTools.

              So I wonder if it should be invalid to return a null token here.

              Shivani Sharma

              Thanks! I was adding the changes to always have this be initialized to no-op id in the follow up CL, but actually moving these changes here so this CL is safe. Also added DCHECKs for id to be non-empty before the network context mojo calls are called.

              dullweber@, PTAL at *private_ai*, thanks!
              My understanding is that PrivateAI WebSocket connections are browser-wide operations not associated with any page/frame, so no Connection Allowlist restrictions should apply, thus the CL adds the no-op network_restricitons_id to it.

              torne@: PTAL at aw_preconnector, thanks!

              My understanding is that the Preconnect in this file is a Preconnect initiated at the Profile level and hence is out of scope of connection allowlists which applies to document/workers initiated Preconnect and other requests. Hence passing a No-op network_restrictions_id.

              nit: prefer CHECK in new code

              Shivani Sharma

              Done but with NotFatalUntil for M165 (over 6 months from now) to be on the safe side. Hope that's fine.

                chrome-sig...@google.com: PTAL at components/signin/internal/identity_manager/account_fetcher_factory_gaia.cc, thanks!

                My understanding is that account capabilities fetches are browser-wide sign-in operations not associated with any page/frame, so no Connection Allowlist restrictions should apply. Hence passing a no-op network_restrictions_id.

                [Connection-Allowlist] Non-optional network_restrictions_id

                This CL should have no functional changes.

                This CL is the first in a series that make network_restrictions_id
                non-optional so that consumers (existing and future) can make a
                well thought-out decision for how Connection Allowlists apply to their
                network request. Next CL will also make URLLoaderFactory params
                network_restriction_id to be non-optional.

                It does the following:
                - Always creates a network_restrictions_id for a document (workers
                already did that).
                - Adding `GetNoOpNetworkRestrictionsId()` for cases where CA should not
                be applied.
                - Adding `GetTODONetworkRestrictionsId()` and
                `GetTestNetworkRestrictionsId()` to
                explicitly categorize placeholder IDs used in unimplemented code paths
                and tests, respectively.
                - Updating signatures of NetworkContext functions to pass the
                non-optional network restrictions ID.

                Bug: 492456054
