Use alloc_size attribute on *alloc functions malloc and family were not declared with __attribute__((alloc_size)). This was (sometimes) preventing FORTIFY_SOURCE related functions from knowing the size of the buffer it's dealing with, inhibiting FORTIFY_SOURCE protections. Add __attribute__((alloc_size)) Information about the alloc_size attribute can be found at http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html Change-Id: Ia2f0a445f0170a7325f69259b5e7fb35a9f14921
