Many DLLs seem to be loading before chrome_elf.dll on Win10

Project Member Reported by scottmg@chromium.org, Mar 10 2017 
In https://bugs.chromium.org/p/chromium/issues/detail?id=700371 we discovered that crash init was broken again, but only on win7 this time.

chrome_elf was accidentally loading advapi32.dll in DllMain, which is bad. However, it works fine on win10 because that dll's already loaded. But why is that dll already loaded?? Here's a log from windbg on win10 for the current stable 57.0.2987.98 (64-bit).

Is this bad? (in particular that all the modules of the world appear to be loading before we get around to chrome_elf.dll?)

Comment 1 by scottmg@chromium.org, Mar 10 2017 

Here's the load from Win7 for comparison:

which looks like we'd want it to look from my understanding.

Comment 2 by scottmg@chromium.org, Mar 10 2017 

I guess it's apphelp/apppatch64 that's messing things up? So maybe it's only on my/some win10 machines?

I'll try setting up a vanilla Win10 VM to compare there next I guess.

Comment 3 by scottmg@chromium.org, Mar 10 2017 

Here's the results of a clean Win10 x64 1607 install, then chrome x64 m57 stable, then windbg:

So I don't think chrome_elf is effective on Win10 at the moment, and we're always getting AppPatch64'd which might not really be teh awesomest either.

Comment 4 by wfh@chromium.org, Mar 10 2017 

can you check the environment for the __COMPAT_LAYER variable maybe?

c.f. issue 694689

Comment 5 by scottmg@chromium.org, Mar 10 2017 

No __COMPAT_LAYER. Maybe AppPatch64 isn't compat? I'm not sure what it is, but it looks like it's mucking up our DLL loads anyway.

So, looks like we're getting shimmed for ConfigurePTPScrolling whatever that is, which in turn causes the earlier-than-us DLL loads.

I'm going to guess not Peer-To-Peer Scolling. How about Precision Touch(p)ad https://msdn.microsoft.com/en-us/windows/hardware/commercialize/design/component-guidelines/precision-touchpad-tests .

Anyone know anything about precision touchpads, and how we might avoid being shimmed for them? Otherwise, we may as well remove chrome_elf as it's not doing anything on 10.

Comment 9 by scottmg@chromium.org, Mar 11 2017 

I tried this in build/win/compatibility.manifest

      <windowsSettings>
        <highResolutionScrollingAware
          xmlns="http://schemas.microsoft.com/SMI/2013/WindowsSettings">
            true
        </highResolutionScrollingAware>

        <ultraHighResolutionScrollingAware
          xmlns="http://schemas.microsoft.com/SMI/2013/WindowsSettings">
            true
        </ultraHighResolutionScrollingAware>
      </windowsSettings>

(and also setting it to false) but doesn't make any difference either way, we still get shimmed.

Comment 10 by scottmg@chromium.org, Mar 11 2017 

Per Rob, trying to rename chrome.exe to khrome.exe changes things slightly for the better, but we still get apphelp and so advapi32 too early.

It seems like we need to do some outreach here to Microsoft to determine why we were added, and if there's something we can fix to be removed.

Comment 11 by robliao@chromium.org, Mar 11 2017 

Microsoft seems to have recently added a blanket policy to Chrome.

If the application matches the following, the shim will be applied:
 * Filename: chrome.exe
 * FILE_DESCRIPTION: Google Chrome
 * COMPANY_NAME: Google Inc.

Creating a Hello World like program with the above will result in running with the patched environment.

We'll need to talk to Microsoft to update the database.

<sigh> Well that explains why this behaviour doesn't get flagged on the chrome_elf tests on win10 bot.  It doesn't match the app filter - we don't test chrome_elf with a full chrome.exe.  I'd be very interested to know why they added us to some rando shim policy.

It might be worth adding some sort of test that launches one full chrome.exe process during chrome_elf tests.  Something like ChromeElfLoadSanityTest that checks for user32.dll.

Comment 13 by scottmg@chromium.org, Mar 20 2017 

That's what I saw looking at the appcompat DB in #c6 too, but even when the binary is renamed we still get advapi32 before chrome_elf.dll due to apphelp.dll (see #c10).

Do we know why that's happening and why it's not caught by tests?

Comment 14 by robliao@chromium.org, Apr 4 2017 

Did we get Microsoft to engage on this or should we ping them again?

Comment 15 by penny...@chromium.org, Apr 5 2017

Hey Rob, Scott.... I just want to confirm that one of you is reaching out to MS about the shimming for scrolling/touchpad.  I had kind of assumed you were?  Please assign this ticket to yourself if you're communicating with Microsoft about the shimming.


WRT #13, I've opened another ticket (crbug/708756) for advapi32/usermode import dependencies sneaking in.

Tests are here: https://cs.chromium.org/chromium/src/chrome_elf/elf_imports_unittest.cc

Looks like advapi32 was unfortunately added to the chrome_elf import whitelist in the tests in: https://chromium.googlesource.com/chromium/src/+/69086d7673ae14680c6451cec3b1160942885327

Let's move that discussion to the new ticket and leave this ticket for the Microsoft shimming (that we have no control over from inside chrome and elf)!

Comment 16 by penny...@chromium.org, Apr 5 2017 

I get the feeling apphelp.dll might be from a shim/appcompat situation as well.  Just based on the tests not blowing up.

Comment 17 by scottmg@chromium.org, Apr 5 2017 

I don't think anyone has made any inquiries to Microsoft.

Comment 18 by penny...@chromium.org, Apr 5 2017 

Confirmed: apphelp.dll is the AppCompat API dll (>=vista).

Comment 24 by brucedaw...@chromium.org, May 8 2018 

Microsoft's eventual reply, from August 2017, was:

"The ConfigurePTPScrolling shim has been removed from RS3 builds on or after 16259 and your input lead has been directly engaged with our input team."

So, as of the Fall Creators Update this issue should be resolved. Is there anything else we need to do?

Comment 25 by brucedaw...@chromium.org, May 8 2018

Status: Fixed (was: Untriaged)
Marking as fixed. Reopen with details if needed.

Comment 26 by scottmg@chromium.org, May 8 2018 

An integration test would be nice, but I guess since we're mostly at the whim of the OS it'd be difficult to run in all the configs it'd need to run.
