2017-06-29Cleanup call expression handling in fm2jsRyan Harrison
Remove handling of arbitrary function calls, and only allow supported function calls. Issues with the lexer being overly permissive led to large blobs of javascript being dropped into the output. Specifically driver code was assuming that anything marked as a function would just be an identifier that could be inserted into the javascript, but the lexer marks things like ()()() as a function, which would lead to the following JS being inserted as an identifier. This change is intended to be a patch for the specific issue that was being seen from the fuzzer test, and further work will be needed to make the lexer more strict. BUG=724913 TEST=Ran fuzzer test case. Ran unittests,embeddertests,corpustests.

2017-05-20Use observed ptrs from CFGAS_GEFont back to its font mgrs.chromium/3106Tom Sepez
CFGAS_GEFonts are ref counted, and its a good thing since they are managed by at least three different font managers: CFGAS_FontMgr, CXFA_PDFFontMgr, and CXFA_FontMgr. None of these have a clear claim to ownership of the CFGAS_GEFont. CFGAS_GEFont has back-pointers to two of these, CFGAS_FontMgr, and CXFA_PDFFontMgr, and they could each outlive the other. Thus the font needs to watch for destruction of either of its managers, so as to stop using it after its gone.

2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.
