qrexec policy NewStatus is unclear

grepping new status shows that anon-vm will target anon-gateway.

$ cd /etc/qubes/policy.d
$ grep -R NewStatus
80-whonix.policy:whonix.NewStatus     *         @tag:anon-vm      @tag:anon-gateway allow  autostart=no
80-whonix.policy:whonix.NewStatus     *         @anyvm            @anyvm            deny

But qrexec-policy-graph shows that a Workstation anon-whonix-example that has a separate Gateway sys-whonix-example uses sys-whonix for whonix.NewStatus.

$ qrexec-policy-graph --source anon-whonix-example --target sys-whonix
digraph g {
  "anon-whonix-example" -> "sys-whonix" [label="whonix.NewStatus" color=red];
}

Is this something that should be added to the Multiple Gw intructions?

I’ve already done that, but that is in VM.
The dom0 policy should command it.
Any workstation can use any gateway for sdwdate if they wish…

Anything that requires manual edits by the user in the VM or in dom0 is a bad design anyhow.

Not sure if the re-design proposal in ⚓ T930 whonix.SdwdateStatus service starts VMs that were killed would fix it.

Various discussions in various tickets such as qrexec autostart=no and new policy format by adrelanos · Pull Request #13 · QubesOS/qubes-core-admin-addon-whonix · GitHub

So this needs probably more work than just more manual dom0 editing documentation.

Maybe Qubes should tag Workstations according to gateway, this makes much easier to enforce the policies via @tag:something.

For example, Gateway is created, names sys-whonix-test, receives tag anon-gateway-sys-whonix-test. Every Workstation that assigns the above Gateway to be its NetVM will receive the tag anon-vm-gateway-sys-whonix-test.

Of course the tags should have a better name, but putting the name according to the domain name makes it easier to locate.

Qubes already puts tags anon-vm and anon-gateway when the AppVMs are created anyway.

Yes, it still requires editing the policy with the above tag response.

But anyway, I don’t have other idea on how to keep Workstations not connecting to other Gateways via qrexec without dom0 policy.

An additional tag perhaps. The existing ones are/might be re-used for other purposes already. Or some other qrexec feature. “Qrexec only to the Net Qube I am connected to.”

In any case, this is too complex. I cannot even foresee when this would happen unless contributed by a volunteer. Would have to be discussed upstream at Qubes.

Adding to this, they first have to prohibit a anon-vm to have a NetVM that is not anon-gateway. Then this second part would be closer to foreseeable.
