add origin attributes into nsIDocShell. v8
29.25 KB, patch
Details | Diff | Splinter Review
See Jonas' comment in https://bugzilla.mozilla.org/show_bug.cgi?id=1209162#c46 also we need to modify nsDocShell::GetOriginAttributes for this.
Assignee: nobody → allstars.chh
Hi, Jonas Do you want to add this method into nsDocShell or nsIDocShell.idl ? Because I added originAttributes into nsILoadContext.idl in Bug 1165466 However nsDocShell implements nsIDocShell and nsILoadContext, so if we want to add this into nsIDocShell, it might make things more complicated, for example, originAttributes is a read-only attributes in nsILoadContext but has a setter in nsIDocShell.
Flags: needinfo?(jonas)
If you name the attribute 'docShellOriginAttributes' in nsIDocShell, then it should be no problem

Summary: Add nsDocShell::SetOriginAttributes → Add docShellOriginAttributes in nsIDocShell
Comment on attachment 8694145 [details] [diff] [review] WIP patch. Hi Jonas Could you take a look on this? I didn't remove those SetIsApp and SetIsBrowser... functions from nsIDocShell, as I found out some Desktop code will use set/getIsApp. Feel free to comment if you have other thoughts. Thanks
Attachment #8694145 - Flags: feedback?(jonas)
I might remove SetIsPackage/SetIsApp/SetIsBrowserInsideApp from nsIDocShell, but not sure should I do the same for those getters like isBrowserElement, isApp, isBrowserOrApp? For checking isBrowserElement is easy, they could just check the mInBrowsr flag from OriginAttributes, however for isApp and isBrowserOrApp, callers need to check if it's not NO_APP_ID nor UNKNOWN_APP_ID as well. not sure if I should do it here, comments are welcome :D

Review of attachment 8695741 [details] [diff] [review]: ----------------------------------------------------------------- In the end I still keep SetIsApp and SetIsBrowserInsideApp because I realized these two functions will set the mFrameType properly. For example, an iframe inside <iframe mozbrowser mozapp> should have a valid 'appId', but its mFrameType should still remain 'regular' However I did removed SetIsPackage and SetIsUserContextId from nsIDocShell.

Attached patch rename to originAttributes (obsolete) — — Splinter Review
rename it back to originAttributes if we think it's easier.
Comment on attachment 8695741 [details] [diff] [review] Patch. Review of attachment 8695741 [details] [diff] [review]: ----------------------------------------------------------------- This is definitely a step in the right direction. However I still think that there's a few things we need to do: Why do we still have setIsApp and setIsBrowserInsideApp on docshell? Doesn't that mean that we now store two appids in docshell? That seems bad since they can get out of sync. Similarly, why do we need the docShell->SetIsBrowserInsideApp and docShell->SetIsApp call in TabChild::NotifyTabContextUpdated? Does this mean that TabChild also tracks two types of appids? Generally though it seems like this patch is definitely in the right direction. So if you prefer we can land this as-is and remove the functions from docshell as a followup (though you'll need to merge with the changes in bug 1195881 which just landed). Let me know.

Ooh. I see. We should figure out a better solution for that. Could you add a SetFrameType function on nsIDocShell instead?

I found a conflict when I update to latest m-c, from Bug 1239420. However I'd like to confirm with Jonas and Baku first, Jonas has suggested we use inheritance for origin attributes back in Bug 1209162 And in this bug, when the DocShell is created, it will inherit the origin attributes of the document from the parent DocShell. However in Bug 1239420, when a user context id is set, it will also set the user context id to the child DocShell, that makes me confused about the inheritance of user context id, it looks to me we should leave userContextId out of those Inheritance functions and set it dynamically? Thanks
Flags: needinfo?(jonas)
Flags: needinfo?(amarchesini)
My understanding of how userContextIds are intended to work is that we always set the userContextId for a tab before we load anything in it. I'm not sure what the exact UX is, but if the user is able to change context on an existing tab, we should always do that by reloading the toplevel document currently in the tab. Kate, can you confirm? In fact, I think we should make SetOriginAttributes assert if the docshell contains anything other than an about:blank document (unfortunately I'm not sure what the best way is to test that).
Flags: needinfo?(jonas) → needinfo?(kmckinley)
There is no way for a user to change the context for a specific tab, and a tab should not change its userContextId after it starts loading. If the user wants to change contexts, they can open a new tab. It is highly likely in e10s that a change in userContextId will cause intermittent crashes.

We use setUserContextId() also when we are restoring sessions. In this case the content can be different than about:blank. For instance it can be about:sessionrestore. Hopefully it will be always an about:something page. Plus: in the docShell chain, we can have some remote content. This means that the parent docshell is still in the parent process (still using 'content' docshell type) but the child is a remote one. This means that we must propagate the UCI from parent to child. Plus: the reason why bug 1209162 is doing something wrong, is because we cannot inherit UCI from parent to child without checking if they are of the same type (chrome/content/other). I guess we don't want to use UCI in chrome docShells, but just in content ones.
Flags: needinfo?(amarchesini)
I think that we should never change the originAttributes of a docshell when it contains a document. Not even a about:sessionrestore document, ideally not even an about:blank document. Could you try to add an assertion in SetOriginAttributes which verifies that mContentViewer is null?
Thanks for the answer, Jonas, Kate and Baku. I still have some questions in mind, (In reply to Andrea Marchesini (:baku) from comment #27) > We use setUserContextId() also when we are restoring sessions.

I guess we don't want to use UCI in chrome > docShells, but just in content ones. 1. Since you mentioned 'propagate the UCI from parent to child (with the same mItemType)', so do we need some DocShellOriginAttributes.InheritFromParentDocShell ? actually I've added this in Bug1165466, Jonas said that child docShell should NOT inherit OA from parent docshell, but from the OA of document from parent docshell. Therefore we changed it in Bug 1209162 From baku's comment, when child docShell wants to inherit OA, it also needs to look at the itemType of parent docshell, which doesn't exist in the parent's document. So do we need to add InheritFromParentDocShell back? 2. Setting child docshell's UCI is for something like Session Restore or about::someting, but Jonas said (In reply to Jonas Sicking (:sicking) from comment #28) > I think that we should never change the originAttributes of a docshell when > it contains a document. Not even a about:sessionrestore document, ideally > not even an about:blank document. I am confused that whether we should set child docshell's UCI or not.:P But if we should, so my understanding is that in these cases the child docShells have been created already, but didn't load any document yet, is this correct? So I'd add assert as Jonas requested. (In reply to Jonas Sicking (:sicking) from comment #28) > Could you try to add an assertion in SetOriginAttributes which verifies that > mContentViewer is null? Thanks

Ideally it shouldn't even have a document (i.e. mContentViewer should be null). So the question should ideally be irrelevant since there should be nowhere to propagate the UCI to. It would be great to add an assertion to verify that that's the case though. > 2.

I don't think there should ever be a child docshell when SetOriginAttributes is called. During session restore we should be creating new tabs for any page which has a non-empty UCI.

rebase, I tried to add assert(!mContentViewer) when calling setOriginAttributes However it causes many crashes on try, and seems to be related to SessionRestore, I'll probably file another bug to track this.

> Tiny bit annoying to move this kind stuff outside docshell. Is there any chance to keep this logic in > DocShell? Actually, the place where I'd like this logic to end up is in DocShellOriginAttributes::InheritFromDocToChildDocShell. That function should eventually take just an nsIContent* which is the <iframe>/<xul:browser>/<frame> element that we're inheriting from. That'll follow the pattern of other *OriginAttributes::InheritFrom* functions. But I think we should do that as a followup.
(In reply to Andrea Marchesini (:baku) from comment #37) > With your patch, how do we propage the UserContextId to the child docShell? There really should never be any child docshells when we set the OriginAttributes on a docshell. If there is that would indicate that we have a "real" document in the docshell, and we can't mutate the OriginAttributes of a running document. That would be like changing the principal of a running document.
DocShellOriginAttributes sounds good too. Certainly better than moving more and more stuff to nsFrameLoader. Though, DocShellOriginAttributes itself can't set stuff like docshell mFrameType.
I don't really understand the frametype business. So far we're just keeping it as-is other than shuffling how it gets set. I agree that it's unfortunate to have to set it separately, but it's better than what we have now. But maybe we could set the frametime in SetOriginAttributes? I had not thought about that possibility. I don't know if that is possible?

And yes, the patch does seem to inherit origin attributes from parent document in nsFrameLoader (but it inherits also random bits from chrome docshell). The inheritance should be handled somewhere in docshell, IMO.

I'd be fine with making the inheriting code explicitly forbidding anything from being inherited from chrome document to any contained content docshells. Fhat seems to do the right thing for all properties that we have in OriginAttributes for now. If we eventually move private browsing to become an OriginAttribute (which I think would simplify a lot of things), then it might make sense to have the private-browsing flag be set on the chrome window and then inherit into the content docshells. I'm not sure. We can solve that when we get there. > The inheritance should be handled somewhere in docshell, IMO. Happy to let you decide where what code should go. The only thing I would say is that this bug is blocking a lot of other work and I think already significantly improves the flow of OriginAttributes. So it might be good to improve things in stages. Up to you.

After reading your Comment 43, My understanding is that when a child docshell is added onto a parent docshell, inheritance should propogate the OA, this is what my patch is doing now.

The userContextId is currently inherited from chrome since it gets set in tabbrowser.xml at tab creation on the tab when you do File->New Contextual Identity Tab.

I'm not sure. We can solve that when we get there. In this case, it would be no different from how userContextId works now.

I don't think we can only add this to nsDocShell::AddChild. I don't think that would work for e10s. Currently the way things work is that nsFrameLoader:MaybeCreateDocShell gathers information into an DocShellOriginAttributes and then sets that either on the child docshell, or the TabParent in which we will eventually create a inner docshell. We'll need something like that in the future as well. One thing to keep in mind here is that we need the parent process to safely store at least some of the origin attributes so that we can get dependable information even if the child process is hacked. For example the signed package ID is something we need to store in the parent process's TabParent. The best way to do this is likely to store a DocShellOriginAttributes in the parent, and then run code similar to [1] to verify that the child process isn't lying. In short, I think we should keep storing a DocShellOriginAttributes in the TabParent. And we need to set the information there without going through the child process docshell.

ni? for smaug for Comment 45, "But what I am still not sure is should we set origin attributes to the child docshell when we call origin attributes on the *parent* docshell, can you confirm? Since Jonas says there shouldn't be any child docshell existing when we call setOriginAttributes." I'd really like to get an agreement on this, but it looks to me that Jonas says "We shouldn't", and smaug and baku say "We should". And also check Jonas' comment 48 for the AddChild explanation. Thanks

There absolutely should not be any child docshells when SetOriginAttributes is called. If there is that is a bug. Can you add an assertion and see if we hit it? If the assertion is not triggered, then I am right :) In fact, there really shouldn't be any other document then an about:blank document in the docshell when SetOriginAttributes is called. If there is then that's a very serious security bug. We should, in a followup bug, see if we can make it possible to assert that when SetOriginAttributes is called, that mContentViewer is null, which means that there is no document at all (and hence can't be any child docshells).

This is what Jonas reviewed before. I moved the assertion to Part 2.

Flags: needinfo?(bugs)
The OriginAttributes of a Document is a function of the OriginAttributes of the Document's docshell. So if the OriginAttributes of the docshell changes, that can well mean that the OriginAttributes of the Document should change. But the OriginAttributes of a Document is part of the Document's origin and the documents principal. It affects things like permissions, cookies, and indexedDB data that is available to that Document. I feel strongly that we don't want the principal of a running document to change such that it affects the permissions, cookies and indexedDB data available to that document. The fact that the document.domain of a document can change is enough of a problem already, and this would be significantly worse. So I definitely think that changing the OriginAttributes of a docshell after it has started being used is a bug. That was certainly the intent that bholley and I had when designing OriginAttributes. It actually worries me enough that we've instantiated the about:blank document by the time that SetOriginAttributes is called. I'd really like to see that fixed. But in a separate bug likely.
I'm totally fine with allowing SetOriginAttributes call only when there is about:blank and not child shells. And if you're worried about about:blank, we could try to push SetOriginAttributes handling to happen right after docshell is created, not some random time later. The hard part is session restore, but even that should be doable. Like we could replace the existing docshell when setting originattributes on a frameloader or tabchild or something. (though better would be to know originattributes before frameloader or tabchild is created) (and sorry, I don't know all the background for originattributes, that stuff just started to show up at some point ;) )
I've got a full try result. https://treeherder.mozilla.org/#/jobs?repo=try&revision=45a8004b0f04&selectedJob=16087995 Some tests fail in the assertion of "about:blank", I didn't figure out the root cause yet, but mostly the case is when loading another URI, gBrowser still keeps the previous URI, so when SessionStore.jsm is going to recover the session it will triggger the assert. I'll file a follow-up for checking this.
now assert on the no child docshell will also have try error https://treeherder.mozilla.org/#/jobs?repo=try&revision=dafbc43549ab&selectedJob=16155906 So I'll move Part 2 as a seperate bug.

We inherit random stuff from chrome docshell to content docshell. And I'm not talking about taking attributes from xul:browser, but whatever is defined in chrome document's principal. We sure need to check the type of the docshell, and possibly also the app type before inheriting anything? (it is not clear to me whether we want to inherit all of origin attributes in case the app id changes) So, we need a whitelist here and inherit from doc's principal only in the cases we really want, not always. Remember, this same code is called for <xul:browser type="content"> containing web pages and <html:iframe> inside web pages. (Random wondering. Why does nsFrameLoader::GetNewTabContext always use usercontextid. Do we let apps to set that on html:iframe too? But non-OOP case does check that the element is in xul namespace)

Hopefully InheritFromDocToChildDocShell is the one place deciding what all gets inherited.
Comment on attachment 8720218 [details] [diff] [review] Part 1: add nsIContent to InheritFromDocToChildDocShell Review of attachment 8720218 [details] [diff] [review]: ----------------------------------------------------------------- I think we should keep things simple in order to move things forward here. Rather than add the nsIContent argument to DocShellOriginAttributes::InheritFromDocToChildDocShell, just make nsFrameLoader::MaybeCreateDocShell not call DocShellOriginAttributes::InheritFromDocToChildDocShell if the element is a xul:browser element. Then, in a separate bug, we should add the nsIContent argument, but we should also move a lot more handling from nsFrameLoader::MaybeCreateDocShell to DocShellOriginAttributes::InheritFromDocToChildDocShell. Specifically what DocShellOriginAttributes::InheritFromDocToChildDocShell should do is: * Check if it's a xul:browser element *and* the element has type=content (or whatever syntax it is that we use to create content docshells), and if so set the OA to its default values, rather than inherit from the nsIContent. * Check for usercontextid attributes. This should be done even if the nsIContent is a xul:browser and/or has type=content. * Check for mozapp and mozbrowser attributes. This should only be done if the nsIContent is a html:iframe or a html:frame. * Maybe other things that I'm missing. All of this is clearly too much to do in this bug. Which is why I would encourage us to do it later. For now, I would say, just make nsFrameLoader::MaybeCreateDocShell not call DocShellOriginAttributes::InheritFromDocToChildDocShell if the element is a xul:browser.

Mostly in tests written in JS from Necko, see https://bugzilla.mozilla.org/page.cgi?id=splinter.html&bug=1165466&attachment=8665349, those are the tests implementing nsILoadContext in JS.
Seems silly to keep an interface scriptable just for tests. However more and more other work is being held up by this patch landing, so I'd rather not block this on rewriting tests. I'd rather consider that for a followup bug.
