This is v2 of my series of stuff from Debian.  (I already pushed the
uncontroversial parts of v1, so those patches are now missing from
v2.)  The remainder are build fixes, and addressing the namespace
pollution of the pygrub `fsimage' libraries by renaming it to
`xenfsimage'.

Hans van Kranenburg (1):
  tools/xenstore: Re-introduce (fake) xs_restrict call to preserve ABI

Ian Jackson (11):
  tools/Rules.mk: Honour PREPEND_LDFLAGS_XEN_TOOLS
  INSTALL: Mention kconfig
  gdbsx: Honour LDFLAGS when linking
  pygrub fsimage.so: Honour LDFLAGS when building
  xenmon: Install as xenmon, not xenmon.py
  tools/debugger/kdd: Install as `xen-kdd', not just `kdd'
  xenstore.h: Put ( ) around XS_* define shifts
  tools/libfsimage: Bump soname to 4.12
  tools/libfsimage: Add `xen' to .h names and principal .so name
  tools/pygrub: Add `xen' to fsimage python module name
  tools/libfsimage: Rename /usr/lib/fs to /usr/lib/xenfsimage

Firstly, add a reference to the documentation for the kconfig system.

Secondly, warn the user about the XEN_CONFIG_EXPERT problem.

This seems to have been simply omitted.  Obviously this is needed when
building and not just when installing.  Passing only when installing
is ineffective.

Adding the implementation language as a suffix to a program name is

From: Hans van Kranenburg <hans@knorrie.org>

libxenstore3.0 in Xen 4.8 had this function.  We don't really want to
bump the ABI version (soname) just for this, since we don't think
there are actual callers anywhere.  But tools complain about the
symbol going away.

So, provide a function xs_restrict which conforms to the original
semantics, although it always fails.

These definitions were not properly protected from unwanted operator
precedence interactions.

Existing use sites in-tree all use & or |, so this does not change any
actual behaviour in-tree.

The same seems likely to be true in external callers.

This library does not have a stable ABI promise.  As far as we know it
is used only by pygrub.  Bump its soname to the Xen version (and
intend to change it each time).

`fsimage' is rather general.  And we do not expect this library to be
very useful out of tree because of its unstable ABI.

So add the word `xen'.  This will avoid naming conflicts with anyone
else's fsimage library.

This module should be called `libxenfsimage' for the same reasons that
the C library should.

Again, avoid namespace pollution.  These paths are purely internal to
libfsimage and its fs-specific modules, so no visible change from the
outside.

Sure, if you think so.

Juergen, something like:

 * The fsimage library used by pygrub, which does not have a stable
   ABI, and the corresponding python module, have been renamed to
   `xenfsimage' (to reduce namespace pollution).  Any out-of-tree
   users of this library will have to be updated.

Thanks,
Ian.

No, this was in the changes that I copied back from Ubuntu, it was
written by Stefan Bader:

---- >8 ----

Description: Re-introduce fake xs_restrict API call
 libxenstore cannot remove an API function without changing its version
 number. As long as we want to remain with 3.0 we have to keep it around.
 Debian might decide to increment the version at some point but we do not
 know how and when. So for now keep the version stable.
