Re: Trust model for raw QPs

Currently, for an app to open a raw QP from user space, we (verbs) require

problematic on some of the environments.

Well yes it is but the kernel mod is a one line to get rid of this
problem.

Suppose we allow to user to provide source mac+vlan when creating the QP or
when modifying its state, and the HW can enforce that -- in that case I think
its OK to remove that restriction e.g ala what is allowed today with user
space UD QPs when the fabric is IB.

Well yes that would mean that the source mac and vlan are configured with
admin permissions and then the app would run without within the
constraints established in priviledged moded.
