So, I'm not familiar with all of the CFI protections available in clang, but is full CFI actually implemented in CLANG? Especially with C/C++, there are a lot of potential attack vectors that would need to be closed (stack smashing, ROP, Vtable corruption). From a laymans perspective, some of these need full memory corruption protection. Any references would be appreciated. The last time I had to adress CFI in C, static analysis (with greater precision than CLANG had) was involved.
