[Info-vax] Throwhammer, remote Rowhammer via RDMA (was Re: CVE-2018-8897 Privilege Escalation due to widespread misunderstanding of x86-64 privileged instruction semantics)

[Stephen Hoffman]

More security fun, a remote rowhammer via RDMA.

Which means memory-level rowhammer detection, or faster or smarter 
(TRR/pTRR) refresh support.  ECC alone isn't quite enough.

DDR-related hardware updates for Itanium and Alpha systems are just not 
going to happen.
