Bart Van Assche 7672eb4cb5 valgrind: Support Xen toolstack process ioctls 
From: Ian Campbell <Ian.Campbell@citrix.com>

Under Xen the toolstack is responsible for managing the domains in
the system, e.g. creating, destroying, and otherwise manipulating
them.

To do this it uses a number of ioctls on the /proc/xen/privcmd
device. Most of these (the MMAPBATCH ones) simply set things up such
that a subsequenct mmap call will map the desired guest memory. Since
valgrind has no way of knowing what the memory contains we assume
that it is all initialised (to do otherwise would require valgrind to
be observing the complete state of the system and not just the given
process).

The most interesting ioctl is XEN_IOCTL_PRIVCMD_HYPERCALL which
allows the toolstack to make arbitrary hypercalls. Although the
mechanism here is specific to the OS of the guest running the
toolstack the hypercalls themselves are defined solely by the
hypervisor. Therefore I have split support for this ioctl into a part
in syswrap-linux.c which handles the ioctl itself and passes things
onto a new syswrap-xen.c which handles the specifics of the
hypercalls themselves. Porting this to another OS should just be a
matter of wiring up syswrap-$OS.c to decode the ioctl and call into
syswrap-xen.c. In the future we may want to split this into
syswrap-$ARCH-xen.c but for now this is x86 only.

The hypercall coverage here is pretty small but is enough to get
reasonable(-ish) results out of the xl toolstack when listing,
creating and destroying domains.

One issue is that the hypercalls which are exlusively used by the
toolstacks (as opposed to those used by guest operating systems) are
not considered a stable ABI, since the hypervisor and the lowlevel
tools are considered a matched pair. This covers the sysctl and
domctl hypercalls which are a fairly large chunk of the support
here. I'm not sure how to solve this without invoking a massive
amount of duplication. Right now this targets the Xen unstable
interface (which will shortly be released as Xen 4.2), perhaps I can
get away with deferring this problem until the first change .

On the plus side the vast majority of hypercalls are not of interest
to the toolstack (they are used by guests) so we can get away without
implementing them.

Note: a hypercall only reads as many words from the ioctl arg
struct as there are actual arguments to that hypercall and the
toolstack only initialises the arguments which are used. However
there is no space in the DEFN_PRE_TEMPLATE prototype to allow this to
be communicated from syswrap-xen.c back to syswrap-linux.c. Since a
hypercall can have at most 5 arguments I have hackily stolen ARG8 for
this purpose.

# Platform variants?
#----------------------------------------------------------------------------
# Normally the PLAT = (ARCH, OS) characterisation of the platform is enough.
# But there are times where we need a bit more control. The motivating
# and currently only case is Android: this is almost identical to
# {x86,arm}-linux, but not quite. So this introduces the concept of platform
# variant tags, which get passed in the compile as -DVGPV_<arch>_<os>_<variant>
# along with the main -DVGP_<arch>_<os> definition.
#
# In almost all cases, the <variant> bit is "vanilla". But for Android
# it is "android" instead.
#
# Consequently (eg), plain arm-linux would build with
#
# -DVGP_arm_linux -DVGPV_arm_linux_vanilla
#
# whilst an Android build would have
#
# -DVGP_arm_linux -DVGPV_arm_linux_android
#
# Same for x86. The setup of the platform variant is pushed relatively far
# down this file in order that we can inspect any of the variables set above.

# There now follow some tests for Boost, and OpenMP. These
# tests are present because Drd has some regression tests that use
# these packages. All regression test programs all compiled only
# for the primary target. And so it is important that the configure
# checks that follow, use the correct -m32 or -m64 flag for the
# primary target (called $mflag_primary). Otherwise, we can end up
# in a situation (eg) where, on amd64-linux, the test for Boost checks
# for usable 64-bit Boost facilities, but because we are doing a 32-bit
# only build (meaning, the primary target is x86-linux), the build
# of the regtest programs that use Boost fails, because they are
# build as 32-bit (IN THIS EXAMPLE).
#
# Hence: ALWAYS USE $mflag_primary FOR CONFIGURE TESTS FOR FACILITIES
# NEEDED BY THE REGRESSION TEST PROGRAMS.
# Check whether the boost library 1.35 or later has been installed.
# The Boost.Threads library has undergone a major rewrite in version 1.35.0.
