RFC: Speculative Load Hardening (a Spectre variant #1 mitigation)
...is
region is
guaranteed to be preserved across interrupts and context switches, making
the
return address used in returning to the current code remain on the stack and
valid to read. We can emit code in the caller to verify that a return edge
was
not mispredicted:
```
callq other_function
return_addr:
testq -8(%rsp), return_addr # Validate return address.
cmovneq %r8, %rax # Update predicate state.
```
For an ABI without a "red zone" (and thus unable to read the return address
from
the stack), mitigating returns face similar problems to calls below....
