    libxl: don't close file descriptors 4..255 in libxl__exec
    
    It prevents callers from deliberately passing file descriptors to the child,
    hides any callers who erroneously do so and doesn't deal with all file
    descriptors in any case.
    
    Rather than remove it all together replace it with some debug code
    which checks for open file handles which do not have either O_CLOEXEC
    or FD_CLOEXEC set. To enable the debug set _LIBXL_DEBUG_EXEC_FDS=1 to
    print any open and non-CLOEXEC non-stdio FDs just before libxl__exec
    actualy calls exec. Set _LIBXL_DEBUG_EXEC_FDS=2 to abort if any of
    these exist.
    
    On the basis of this debugging fix some leaked filehandles:
      * The read end of the pipe used to wake the parent from the
        intermediate process during libxl__spawn_spawn was leaked into the
        intermediate process.
      * The file descriptor representing the xl lock was not marked
        O_CLOEXEC (the lock itself is already specified to not be
        inherited across a fork).
      * The file descriptors passed to libxl__exec to be dup'd as
        std{in,out,err} were leaked at their original number. They are
        harmless (an attacker can just as easily use fd 0..2) but close
        anyway since it removes a case which a person evaluating open fd's
        needs to consider.
      * libxl_run_bootloader was leaking the xenconsole pty master into
        the bootloader child process.
      * If the bootloader fails to get as far as opening its end of the
        FIFO then we can also hang, check that the process has not exited
        as part of that loop. (we actually block opening the FIFO too so
        this is only a partial fix for the case where the bootlader has
        crashed quickly).
    
    With these fixes I have tested that device models, bootloaders
    (pygrub) and vncviewers which are spawned via libxl__exec with no
    unexpected file descriptors open, at least in my configuration.

    libxl: add statup checks to libxl__wait_for_device_model
    
    When the device model is starting up push checks for spawn failure down into
    libxl__wait_for_device_model, allowing us to fail more quickly when the 
device
    model fails to start (e.g. due to a missing library or an early setup error
    etc).
    
    In order to allow the select loop in libxl__wait_for_device_model to wake 
when
    the child dies add pipe between the parent and the intermediate process 
which
    the intermediate process can use to signal the parent.

    libxl: pass libxl__spawn_starting to libxl__spawn_spawn.
    
    Passing a libxl__device_model_starting to a generic function and expecting 
it
    to scrobble inside for the generic data structure is a strange interface.
    Instead pass in a libxl__spawn_starting and an opaque hook data pointer.
    
    The for_spawn member of libxl__device_model_starting was annotated with
    "first!", suggesting that someone intended to use pointer casting tricks to
    move between the outer and inner struct. However the field is a pointer not 
a
    inline struct so this doesn't work (and it isn't used this way anyhow). 
Remove
    the comment, and move the field away from the front for good measure.

    libxc: obtain correct length of p2m during core dumping
    
    while implementing core dumping functionality for the libxl driver
    of libvirt, I discovered an issue with mapping pages of a pv guest.
    
    After dumping the core of a pv guest the domain was not cleared up
    properly and some pages were not unmapped. This issue is similar
    to the one reported here:
    http://lists.xensource.com/archives/html/xen-devel/2011-05/msg01314.html
    
    In xc_domain_dumpcore_via_callback in the file xc_core.c the function
    xc_core_arch_map_p2m is called to map P2M_FL_ENTRIES pages to the variable 
p2m.
    But to unmap the pages later, the dinfo->p2m_size has to be set accordingly.
    This was not done, instead a variable named p2m_size was set.
    This way P2M_FL_ENTRIES was always zero and the pages were left mapped.

    libxc: after saving, unmap correct amount for live_m2p
    
    With some help from Olaf, I've finally got to the bottom of an issue I
    came across while trying to implement save/restore in the libvirt
    libxenlight driver.  After issuing the save operation, the saved domain
    was not being cleaned up properly and left in this state from xl's
    perspective
    
    xen33:# xl list
    Name                   ID   Mem VCPUs      State   Time(s)
    Domain-0                0  6821     8     r-----     122.5
    (null)                  2     2     2     --pssd      10.8
    
    Checking the libvirtd /proc/$pid/maps I found this
    
    7f3798984000-7f3798b86000 r--s 00002000 00:03 4026532097 /proc/xen/privcmd
    
    So not all all pages belonging to the domain were unmapped from
    libvirtd.  In tools/libxc/xc_domain_save.c we found that P2M_FL_ENTRIES
    were being mapped but only P2M_FLL_ENTRIES were being unmapped.  The
    attached patch changes the unmapping to use the same P2M_FL_ENTRIES
    macro.  I'm not too familiar with this code though so posting here for
    review.
    
    I suspect this was not noticed before since most (all?) processes doing
    save terminate after the save and are not long-running like libvirtd.

    When a device can't be allocated to dom0 by the IOMMU, don't leave
    dom0 in the "domain" field.  It causes pci_remove_device()
    to crash trying to remove the dev from the domain's list of devices

    Fix Config.mk's cc-option for -Wno-* options.
    
    These disable-warning options are handled specially by GCC:
     (a) they are ignored unless the compiler emits a warning; and
     (b) even then they produce a warning rather than an error
    
    To handle this, modify the test invocation of GCC to compile a
    fragment of code that will always provoke a warning (integer assigned
    to pointer). This works around (a) above.
    
    Then, we grep the compiler's stdout/stderr for the option-under-test,
    the presence of which would indicate an "unrecognized command-line
    option" warning/error. This works around (b) above, letting us
    distinguish between the "integer assigned to pointer" and
    "unrecognized command-line option" warnings.
