HulaHoop closed T530: CPU-induced latency Covert Channel Countermeasures as Invalid.

After running a bunch of tcp ping tests, the conclusion is this attack
is not really effective against TCP like ICMP. The latency is much lower
for TCP pings and though it slightly decreases with cpu stress it is not
consistent. Reloading pages in TBB with cpu stress
on/off does not impact latency readings while doing so with tc
attached has massive latency foot prints - implying it will ironically make such attacks much easier in addition to degrading performance.

The YAJL parser used in libvirt is tiny, modern (written in2007) and has no CVEs. It is an SAX type event-driven parser unlike the vulnerable, top-down recursive descent type that was used in QEMU.

HulaHoop added a comment to T550: Clock Drift Detection.

It turns out the QEMU guest agent warning was not relevant to those who use libvirt. With libvirt a safe parser is used. Breakouts can only happen if a process on the host is designed to parse guest input because there is no way to control that otherwise it should be safe for our uses. This potentially simplifies the design in many respects but a host package will still be needed. I will update the task list.
