The pvshim can only be built 64-bit because the hypervisor is only
64-bit nowadays. The hypervisor build supports XEN_COMPILE_ARCH and
XEN_TARGET_ARCH which override the information from uname. The pvshim
build runs out of the tools/ directory but calls the hypervisor build
system.
If one runs in a Linux 32-bit userland with a 64-bit kernel, one used
to be able to set XEN_COMPILE_ARCH. But nowadays this does not work.
configure sees the target cpu as 64-bit and tries to build pvshim.
The build prints
echo "*** Xen x86/32 target no longer supported!"
and doesn't build anything. Then the subsequent Makefiles try to
install the non-built pieces.
Fix this anomaly by causing configure to honour the Xen hypervisor way
of setting the target architecture.
In principle this user behaviour is not handled quite right, because
configure will still see 64-bit and so all the autoconf-based
architecture testing will see 64-bit rather than 32-bit x86. But the
tools are in fact generally quite portable: this particular location
in configure{.ac,} is the only place in tools/ where 64-bit x86 is
treated differently from 32-bit x86, so the fix is sufficient and
correct for this use case.
It remains the case that XEN_COMPILE_ARCH or XEN_TARGET_ARCH to a
non-x86 architecture, when configure thinks things are x86, or vice
versa, will not work right.
(This is a bugfix to 8845155c83
pvshim: make PV shim build selectable from configure
which inadvertantly deleted the logic to only build the shim for
XEN_TARGET_ARCH != x86_32.)
I have rerun autogen.sh, so this patch contains the fix to configure
as well as the source fix to configure.ac.

Previously, defaulting and checking of some aspects of the domain
config was skipped for stub dms. This has been the case forever.
In ad011ad088 "libxl/xl: Overhaul passthrough setting logic" some
defaulting that was needed for stub dms was moved from
libxl__domain_create_info_setdefault to .._config_setdefault with the
result that for stub dms, libxl__domain_make fails with this
assertion:
xl: libxl_create.c:582: libxl__domain_make: Assertion
`info->passthrough != LIBXL_PASSTHROUGH_DEFAULT' failed.
Fix this by properly doing all defaulting and all checking for stub
dms. This is more correct, but (especially at this stage of the
release) it is necessary to more closely evaluate the effects by
reviewing the body of _config_setdefault. The changes are as follows:
One actual functional change:
* The new passthrough defaulting is properly done. This is what we
are trying to actually fix here.
And a lot of things that make no difference:
* shadow_memkb would now be set. Whether this would be correct is not
entirely clear. It seems better to make this patch (whose purpose
is to fix the passthrough defaulting) *not* include that semantic
change, so here I have included a hunk to explicitly override this.
* FLASK ssid_label is processed. But the actual ssidref is copied
from the guest domain by spawn_stub_dm, and ssid_label is set to
NULL. So no change.
* We set iommu_memkb. But to 0 since passthrough is disabled.
* cpuid pool_name is processed. But this is not set by
spawn_stub_dm. (Arguably this is a bug: stub dms should inherit the
parent cpupool.) The effect is to leave poolid set to 0 and call
libxl_cpupoolid_is_valid but that always succeeds for 0. So no
change.
* Various extra checks are done: reject PCI passthrough for HVM with
POD (stub dm is PV); reject pod + vnuma, or PV + vnuma (stub dm has
no vnuma); reject nested HVM or pod, with alt2pm-hvm (again, stub dm
is PV). So these checks will always pass.

LIBXL_PASSTHROUGH_UNKNOWN (aka "ENABLED" in an earlier uncommitted
version of this code) is doing double duty. We actually need all of
the following to be specifiable:
* "default": enable PT iff we have devices to
pass through specified in the initial config file.
* "enabled" (and fail if the platform doesn't support it).
* "disabled" (and reject future PT hotplug).
* "share_pt"/"sync_pt": enable PT and set a specific PT mode.
Defaulting and error checking should be done in libxl. So, we make
several changes here.
We introduce "enabled", and rename "unknown" to "default".
We move all of the error checking and defaulting code from xl into
libxl. Now, libxl__domain_config_setdefault has all of the necessary
information to get this right. So we can do it all there. Choosing
the specific mode is arch-specific.
We can also arrange to have only one place each which calculates
(i) whether passthrough needs to be enabled because pt devices were
specified (ii) whether pt_share can be used (for each arch).
xl now only has to parse the enum in the same way as it parses all
other enums.
This change fixes a regression from earlier 4.13-pre: until recent
changes, passthrough was only enabled by default if passthrough
devices were specified. We restore this behaviour.

These are now redundant because shadow_memkb and iommu_memkb are now
defaulted automatically by libxl_domain_need_memory and
libxl_domain_create etc. Callers should not now call these; instead,
they should just let libxl take care of it.
libxl_get_required_shadow_memory was introduced in f89f555827
"remove late (on-demand) construction of IOMMU page tables"
We can freely remove it because it was never in any release.
libxl_get_required_shadow_memory has been in libxl approximately
forever. It should probably not have survived the creation of
libxl_domain_create, but it seems the API awkwardnesses we see in
recent commits prevented this. So we have to keep it. It remains
functional but we can deprecate it. Hopefully we can get rid of it
completely before we find the need to change the calculation to use
additional information which its arguments do not currently supply.

Defaulting is supposed to be done by libxl. So these calculations
should be here in libxl. libxl__domain_config_setdefault has all the
necessary information including the values of max_memkb and max_vcpus.
The overall functional effect depends on the caller:
For xl, no change. The code moves from xl to libxl.
For callers who set one or both shadow_memkb and iommu_memkb (whether
from libxl_get_required_shadow_memory or otherwise) before calling
libxl_domain_need_memory (any version): the new code will leave their
setting(s) unchanged.
For callers who do not call libxl_domain_need_memory at all, and who
fail to set one of these memory values: now they are both are properly
set. The shadow and iommu memory to be properly accounted for as
intended.
For callers which call libxl_domain_need_memory and request the
current API (4.13) or which track libxl, the default values are also
now right and everything works as intended.
For callers which call libxl_domain_need_memory, and request an old
pre-4.13 libxl API, and which leave one of these memkb settings unset,
we take special measures to preserve the old behaviour.
This means that they don't get the additional iommu memory and are at
risk of the domain running out of memory as a result of f89f555827
"remove late (on-demand) construction of IOMMU page tables". But this
is no worse than the state just after f89f555827, which already
broke such callers in that way. This is perhaps justifiable because
of the API stability warning next to libxl_domain_need_memory.
An alternative would be to drop the special-casing of these callers.
That would cause a discrepancy between libxl_domain_need_memory and
libxl_domain_create: the former would not include the iommu memory and
the latter would. That seems worse, but it's debateable.

This should calculate the extra memory needed for shadow and iommu,
the defaults for which depend on values in c_info. So we need this to
have the complete domain config available.
And the defaults should actually be updated and stored. So make it
non-const.
We provide the usual kind of compatibility function for callers
expecting 4.12 and earlier. This function becomes responsible for the
clone-and-modify of the b_info.
No overall functional change for external libxl callers which use the
API version system to request a particular API version.
Other external libxl callers will need to update their calling code,
and will then find that the new version of this function fills in most
of the defaults in d_config. Because libxl__domain_config_setdefault
doesn't quite do all of the defaults, that's only partial. For
present purposes that doesn't matter because none of the missing
settings are used by the memory calculations. It does mean we need to
document in the API spec that the defaulting is only partial.
This lack of functional change is despite the fact that
numa_place_domain now no longer calls
libxl__domain_build_info_setdefault (via libxl_domain_need_memory).
That is OK because it's idempotent and numa_place_domain's one call
site is libxl__build_pre which is called from libxl__domain_build
which is called from domcreate_bootloader_done, well after the
defaults are set by initiate_domain_create.

Break out this into a new function. We are going to want to call it

Unfortunately not all of the defaults can be moved into the new
function without changing the order in which things are done. That
does not seem wise at this stage of the release. The effect is that
additional calls to libxl__domain_config_setdefault (which are going
to be introduced) do not quite set everything. But they will do what
is needed. After Xen 4.13 is done, we should move those settings into
the right order.

./configure takes a PYTHON=... argument. You can use this to specify

Fix this. The new logic is:
* if not set, default to `python'
* if not absolute, look it up with type -p
* split into directory and executable name
The results in config/Tools.mk (which contains @PYTHON@ and
@PYTHONPATH@) are identical for both
./configure
./configure PYTHON=/usr/bin/python
so I assert this has no functional change except that now you can say
./configure PYTHON=python
In particular you can now say
./configure PYTHON=python2
./configure PYTHON=python3
The latter is useful if you want python3 (which should probably be the
default, but does not work right now). The former is useful if you
want python2 but your distro has foolishly made "python" refer to
python3.

In d290e32517
"build system: don't let install-stubdom depend on install-tools"
the dependency of install-stubdom on install-tools was removed.
However, this was not correct. stubdom/Makefile contains this:
$(XEN_ROOT)/tools/qemu-xen-traditional-dir:
$(MAKE) DESTDIR= -C $(XEN_ROOT)/tools qemu-xen-traditional-dir-find
As I have written before:
With recursive make, it is necessary for the overall structure of the
makefiles to sequence things so that each directory is entered exactly
once, before its dependent directories are entered. (It is possible
to violate this rule without creating races but it is tricky and
inadvisable.)
Since d290e32517, it can happen that the command for the
qemu-xen-traditional-dir-find rule is run twice simultaneously - once
as a result of $(MAKE) -C tools install, and once as a result of
$(MAKE) -C stubdom install. If you get unlucky, this causes lossage.
(This just happened to me in an osstest flight.)
In principle we could alternatively fix this by lifting the commands
in the qemu-xen-traditional-dir-find target (and perhaps other things
too) into the toplevel Makefile, as was done for mini-os.
But that seems overkill given how bad the stubdom build system is, and
the fact that we think at some point this qemu-trad will go away
entirely. Adding the tools dependency back to the stubdom build is
by and large good enough.
(Someone who really wants to build stubdom without tools is welcome to
do this separation if they really want to.)

CLONE_NEWIPC was introduced in Linux 2.6.19, on the 29th of November
2006, which was 12 years, 1 month, and 14 days ago.
Nevertheless apparently some people are trying to build Xen on systems
whose kernel headers are that old. Placate these people by providing
a fallback #define for CLONE_NEWIPC.
The actual binary value will of course remain constant, because of the
kernel API promise, so this is and will be correct on all platforms
where the CLONE_NEWIPC is supported. (Even if for some reason we miss
the right #includes.)
Of course at runtime this value will not work on older kernels. It
will be rejected as unknown by anything except some pre-2.6.18
kernels. On those kernels we do not want to support dm_restrict, and
an attempt to use it will fail. It is OK for the failure to be a
messy EINVAL syscall failure. (The IPC namespace unshare is necessary
to avoid a suborned deprivileged qemu from causing trouble with shm,
sem, etc.)
On the very old kernels, the feature is totally out of scope.
(We are only interested, here, in making the build work, to avoid
blocking people who aren't using this feature.)

`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 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).

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.

The patch file 00cvs is an import of a new upstream version of
grub1 from upstream CVS.
Unfortunately, in the period covered by the update, upstream changed
the documentation licence from a simple permissive licence, to the GNU
"Free Documentation Licence" with Front and Back Cover Texts.
The Debian Project is of the view that use the Front and Back Cover
Texts feature of the GFDL makes the resulting document not Free
Software, because of the mandatory redistribution of these immutable
texts. (Personally, I agree.)
This is awkward because Debian do not want to ship non-free content.
So the Debian maintainers need to launder the upstream source code, to
remove the troublesome files. This is an extra step when
incorporating new upstream versions. It's particularly annoying for
security response, which often involves rebasing onto a new upstream
release.
grub1 is obsolete and the last change to Xen's PV grub1 stubdom code
was in 2016. Furthermore, the grub1 documentation is not built and
installed by the Xen pv-grub stubdom Makefiles.
Therefore, remove all docs changes from stubdom/grub.patches. This
means that there are now no longer any GFDL-licenced grub docs in
xen.git.
There is no user impact, and Debian is helped. This change would
complicate any attempts to update to a new version of upstream grub1,
but it seems unlikely that such a thing will ever happen.

This is not really very nice.
This line doesn't have much value in itself. The rest of this comment

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
the future, so it wants a licence compatible with osstest's AGPLv3+.

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 of the libxc handle.
ISTM that it is best to do this by providing an interface to get the
underlying library handles for a libxc handle. This kind of interface
is quite common elsewhere and has not caused problems.
libxc is not a stable API so the downside risk of providing this
access is not significant.

A read-only check was introduced for XSA-142, commit ef6cb76026 ("libxl:
relax readonly check introduced by XSA-142 fix") added the passing of
the extra setting, but commit dab0539568 ("Introduce COLO mode and
refactor relevant function") dropped the passing of the setting again,
quite likely due to improper re-basing.
Restore the readonly= parameter to SCSI disks. For IDE disks this is
supposed to be rejected; add an assert. And there is a bare ad-hoc
disk drive string in libxl__build_device_model_args_new, which we also
update.
This is XSA-266.

The 4.10 release preparation was significantly more hairy than ideal.
(We seem to have a good overall outcome despite, rather than because
of, our approach.)
This is the second time (at least) that we have come close to failure
by committing to a release date before the exact code to be released
is known and has been made and tested.
Evidently our docs makes it insufficiently clear not to do that.

When SUPPORT.md uses the syntax
Status, <some thing>: <support status>
the caveats were lost (not footnoted) because they were attached
only to <some thing>.
Caveats occur in running text, so they are necessarily part of a real
section, not an individual status line like that. So attach them to
the RealSectNode, and look there for them.
