1403690 - stylo: Stop whitelisting LookAndFeel::GetColor in the heap write hazard analysis

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect, P2)

Description

[Bobby Holley (:bholley)]

This is a followup issue from bug 1354966 comment 25.

Right now LookAndFeel::GetColor is whitelisted in the heap-write analysis [1]. We have a lock, but that lock lives in Gecko_GetLookAndFeelSystemColor, which means that it wouldn't protect other call paths to LookAndFeel::GetColor, if they exist.

So the first-order fix here would be to whitelist Gecko_GetLookAndFeelSystemColor instead, alongside the other locked stuff.

However, things are extra tricky because bug 1401063 removed the platform API calls from LookAndFeel::GetColor in the gtk case, which means that the analysis (which runs on linux) would actually be if we didn't whitelist Gecko_GetLookAndFeelSystemColor at all. This is kind of a dangerous place to be, so we should probably strip the platform API calls from all the NativeGetColor implementations, which in turn would allow us to eliminate sServoWidgetLock entirely.

The current patches make progress on this, but are visually problematic at least on macOS (where I can easily test). They display incorrect colors in Chrome elements on macOS. The patches attempt to cache colors in nsLookAndFeel::NativeInit(), which seems to be intended for this purpose. But I see that ServoStyleSet::PreTraverseSync calls NativeInit on every traversal: http://searchfox.org/mozilla-central/rev/a4702203522745baff21e519035b6c946b7d710d/layout/style/ServoStyleSet.cpp#420.

Bobby, is NativeInit intended to be a one-time only init? Or is it appropriate to be called per traversal (perhaps to handle changes of OS theming while the app is open)?

Bug 1386915 added NativeInit as a per-traversal call. At the time, only gtk/Linux did anything with NativeInit. This bug may change that and require change to the approach of calling it once per Stylo traversal.

I'm still not entirely sure why this matters. It's called every traversal, but it checks mInitialized and early-returns, so it's just a lazy init routine. I don't know why that's relevant to this bug.

Comment 8

[Bobby Holley (:bholley)]

And summarizing from the meeting:
* We should figure out if it's correct to cache the system colors on all the platforms. If so, we should do it on mac/windows. If not, we should back out the caching on linux, so that our linux-only static analysis properly recognizes that those codepaths trigger widget calls.
* We should probably go ahead and do bug 1403699 immediately, and just lock in Gecko_GetLookAndFeelSystemColor for now.

[Brad Werth [:bradwerth]]

Okay, got this working visually for macOS by doing the color caching as demanded by the first call to NativeGetColor, which is the approach taken by the existing, presumably correct gtk implementation. I'm now asking for review by DOM peers for macOS and Windows to see if this approach is acceptable on those platforms while I move ahead on implementation on Android and iOS.

[Jim Mathies [:jimm]]

For part 2, where is the code that invalidates the cached values when we receive a WM_SETTINGCHANGE?

I've updated all parts of the patch (including part 2 for Windows) to reset the mInitialized variable within the nsLookAndFeel::RefreshImpl() function. That function is called in platform-specific circumstances. On Windows, it is called in response to the WM_SETTINGCHANGE event.

Caching these colors is fine as long as they're invalidated by a call to NotifyThemeChanged, which does seem to be the case.

There are a few instances of end-of-line whitespace in the patch.

I figured it out; the Android implementation was fetching both SystemColors and ShowPassword during the same call, which was problematic. I split the initialization method into two parts, and only init each part when needed, and the tests work again.

> Part 1: Adjust heap write analysis whitelist to include Gecko_GetLookAndFeelSystemColor

Why are we doing this? Isn't the whole point of this patch set to make Gecko_GetLookAndFeelSystemColor not call into any external code? It would seem that whitelisting in this way prevents the static analysis from verifying that this was all done correctly.

You're right; I wasn't thinking clearly. I filed Bug 1412868 to sort this out and I'll have a patch shortly.
