Bug 181339 – WebAssembly: poison JS object's secrets

• Status: RESOLVED
• Resolution: FIXED
• Component: WebAssembly

[JF Bastien]

Separating WebAssembly's JS objects from their non-JS implementation means that all interesting information lives outside of the JS object itself. The only interesting by that could be confused or speculated on are the pointers to the non-JS implementations themselves. This patch poisons each JS object's pointer to non-JS implementation using the poisoning mechanism and a unique key per JS object type origin.

This doesn't do all of the interesting scrambling / poisoning, only JSWebAssembly* -> Wasm*. I'll do the others in a follow-up.

[JF Bastien]

There's a bug in this patch, will fix after taking care of something else.

Order doesn't really matter, but let's keep these alphabetically ordered (with NotPoisoned being the only exception) to help us read the code.  When the list gets large, this will help.

> +            jit.move(CCallHelpers::TrustedImm64(WTF::makeConstExprPoison(JSWebAssemblyInstancePoison)), scratchReg);

I meant to fix this but I haven't done so yet: please remove the WTF:: qualifier here and add "using WTF::makeConstExprPoison" in Poisoned.h.

> +    }

Please add test cases to TestWebKitAPI/.../Poisoned.cpp and PoisonedRef.cpp

This should come before JSCell.h (uppercase before lowercase).

This should come before JSDestructibleObject.h.

IIUC I was running into the same compiler bug Mark had a while ago, with mismatched template deduction with just the reference qualifier differing. That only occurs on current SDK, but not more recent ones... So worked for me! I #if'd these tests out, and luckily am only using the constexpr version of this which doesn't have this bug. I also added a test to ConstExprPoisoned.cpp which I just realized I'd missed. Will see if bots are happy.
