Mentioned last month here:
And just as a demonstration of the limitations of __builtin_object_size, you show how it would have prevented the perf_counter exploit (which is more a statement of how utterly trivial the vulnerability was). It would indeed have prevented it (even with an older 4.X compiler I believe). However, making one small change of having perf_copy_attr() become a global function, and __builtin_object_size suddenly becomes useless. There's tons of real kernel code like that to be found.
