Andrew Cooper 5b42c82f55 tools/libxc: Fix domid parameter types
Mixed throughout libxc are uint32_t, int, and domid_t for domid parameters.
With a signed type, and an explicitly 16-bit type, it is exceedingly difficult
to construct an INVALID_DOMID constant which works with all of them.  (The
main problem being that domid_t gets unconditionally zero extended when
promoted to int for arithmatic.)

Libxl uses uint32_t consistently everywhere, so alter libxc to match.

The only remaining mentions of these addresses are in COPYING files which I
haven't touched.

Some of the changed files are imports from elsewhere, however
filtering them out is tricky, I think it is tolerable to have these
files be modified here and then perhaps reverted on the next sync,
since it's only 1-2 lines and obvious what is going on.

Konrad Rzeszutek Wilk 479dab8498 libxc: xc_physdev_map return -1 and populate errno.
The users of these (qemu) check for a negative value
so we are safe in regards to that. However they
also use the return value to inform the user of the
error.

Jan Beulich 934a5253d9 fix XSA-46 regression with xend/xm
The hypervisor side changes for XSA-46 require the tool stack to now
always map the guest pIRQ before granting access permission to the
underlying host IRQ (GSI). This in particular requires that pciif.py
no longer can skip this step (assuming qemu would do it) for HVM
guests.

This in turn exposes, however, an inconsistency between xend and qemu:
The former wants to always establish 1:1 mappings between pIRQ and host
IRQ (for non-MSI only of course), while the latter always wants to
allocate an arbitrary mapping. Since the whole tool stack obviously
should always agree on the mapping model, make libxc enforce the 1:1
mapping as the more natural one (as well as being the one that allows
for easier debugging, since there no need to find out the extra
mapping). Users of libxc that want to establish a particular (rather
than an allocated) mapping are still free to do so, as well as tool
stacks not based on libxc wanting to implement an allocation based
model (which is why it's not the hypervisor that's being changed to
enforce either model).

Since libxl, like xend, already uses a 1:1 model, it's unaffected by
the libxc change (and it being unaffected by the original hypervisor
side changes is - afaict - simply due to qemu getting spawned at a
later point in time compared to the xend event flow).

tools/libxc, tools/libelf: Relicense under LGPL v2.1

Relicense these two libraries under LGPL v2.1 only except where
individual files already included the "or later" provision.

Copyright holders have been contacted by Stephen Spector and have all
agreed this change.

Removed tools/libxc/ia64/aclinux.h since it appeared to be
unused. There is a separate, more up to date, copy in
xen/include/acpi/platform/aclinux.h which does appear to be used.

Clarify the license of MiniOS privcmd.h under the same terms as other
tools/include/xen-sys headers.

Keir Fraser 5cc436c1d2 libxc: eliminate static variables, use xentoollog; API change
This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).

Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.

There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.

All libxc callers have been adjusted accordingly.

Also update QEMU_TAG for corresponding qemu change.

Keir Fraser d6aaa9ee0f libxc: New hcall_buf_{prep,release} pre-mlock interface
Allow certain performance-critical hypercall wrappers to register data
buffers via a new interface which allows them to be 'bounced' into a
pre-mlock'ed page-sized per-thread data area. This saves the cost of
mlock/munlock on every such hypercall, which can be very expensive on
modern kernels.
