Help with Quanta+ code

Hi,

I am a Ph.D. student at UIUC working with Professor Ralph Johnson. My
research interest is security and software architecture. At this point, I am
surveying existing software architecture for buffer overflow vulnerability
protection.

I need some help understanding the Quanta+ codebase. In particular I have
three questions.

1. Does the C/C++ code use the string library functions (strcpy, strcat,
gets etc)?

2. Or does it use some sort of buffer bounds checking, either by rewriting
the string library, or checking before every buffer operation?

3. Is the bounds checking available from the first release, or it has been
included in a subsequent release? How did the development team go about
making this change in the code?


Any information would be greatly appreciated. Thanks in advance.
