In old kernel-xen MAX_SKB_FRAGS was 18, while nowadays it is 17. This

In order to support auditing of qemu depriv, my audit tool wants to
know the fd of a privcmd handle on which it can easily make
hypercalls. xencall provides such a handle, but has no cooked
facilities for making hypercalls. So I open a libxc handle. That
means I need to get the privcmd fd out

fish it out of the build tree.

I have chosen to licence this utility as LGPL-v2.1-only, similar to
other LGPL elements of the Xen tools, because it may want to be moved
into or combined with osstest or some other project at some point in

This series provides the support in xen.git for auditing whether qemu
file descriptors are deprivileged, as expected with libxl
dm_restrict=1.
The approach I have chosen is to fish the descriptors out of qemu (by
using debugging facilities), and try to make hypercalls etc.
Add mention of LIBXL_QEMU_USER_RANGE_BASE, in case that is what the
user was intending.
