> you could use the vDSO for high-resolution timing but, from an attack perspective, it’s a red herring. Any serious attacker would use RDTSC,
Good point. I was going to say that in general the vDSO is just rdtsc + an offset applied. However they insert a barrier before it usually. That maybe or many not be helpful so I would probably still use rdtsc by itself.
