9pfs support has been a documented feature since Xen 4.9, but QEMU will
not be built with backend support unless VirtFS is enabled, which is
predicated on the libcap and libattr dev packages being installed. This is
not obvious to anyone intending to use 9pfs.
This patch adds an 'enable-9pfs' option to configure which, if specified,
will cause '--enable-virtfs' to be passed to QEMU's configure. This will
cause the dependency on libcap and libattr to be called out if the packages
are not in installed.
For completeness, specifying 'disable-9pfs' will cause '--disable-virtfs' to
be passed to QEMU's confgure and not specifying an option will keep the
previous behaviour of predicating VirtFS on whether the libcap and libattr
packages are installed.

It appears that the test in 01d631028 for ipxe's dependency on rombios
is not good enough. Configuring with --disable-rombios doesn't disable

Fix it by testing the dependency after AC_ARG_ENABLE and AC_ARG_WITH

At the same time, regularise options for ipxe:
--enable-ipxe enable building in-tree ipxe
--disable-ipxe disable building in-tree ipxe
--with-system-ipxe specify a path to be baked into code, disable
building in-tree ipxe, this trumps --{en,dis}able-ipxe

A dedicated Xen driver domain init service starts "xl devd" in domU. But
currently, it is only supplied in the form of a SysV init script, which
systemd users run through a backward compatiblity wrapper automatically
generated by systemd-sysv-generator. This patch adds a (naturally more
lightweight) native systemd unit to be used instead.
The xendriverdomain service is only relevant to domU, but should not run
in dom0. Therefore, the systemd unit uses "ConditionVirtualization=xen",
which evaluates to true in domU and (since systemd version 214, released
on 2014-06-11) to false in dom0. Users or distributors who need to be
compatible with even older systemd versions, but still want to prevent
"xl devd" startup in dom0, could add the following line in [Service]:
ExecStartPre=/bin/sh -c "! grep -q control_d /proc/xen/capabilities"

Changeset 1166ecf ('tools/Rules.mk: Don't optimize debug builds; add
macro debugging information') exposed a bug whereby the autoconf stuff
in tools was setting its own debug value (defaulting to ENABLED, even
for releases) instead of honoring the value set in Config.mk.
After that changeset, if the global build has -D_FORTIFY_SOURCE
enabled (as is the default in CentOS 7 rpmbuild), then the tools build
will fail (because debug builds default to on).
There should be only one place to specify whether to build debug or
not, and Config.mk is already included by the relevant makefiles. So
simply remove the tools/configure debug option and everything falls

They are no longer needed, having been replaced by a daemon for

Worse yet, they seem to be broken for script-based block devices, such
as block-iscsi. This wouldn't matter so much if they were never run
by default; but if you run block-attach without having created a
domain, then the appropriate node to disable running udev scripts will
not have been written yet, and the attach will silently fail.

When the property "clock-frequency" is present in the DT timer node, it
means that the bootloader/firmware didn't correctly configure the
CNTFRQ/CNTFRQ_EL0 on each processor.
The best solution would be to fix the offending firmware/bootloader,
although it may not always be possible to modify and re-flash it.
As it's not possible to trap the register CNTFRQ/CNTFRQ_EL0, we have
to extend xen_arch_domainconfig to provide the timer frequency to the
toolstack when the property "clock-frequency" is present to the host DT
timer node. Then, a property "clock-frequency" will be created in the guest
DT timer node if the value is not 0.
We could have set the property in the guest DT no matter if the property
is present in the host DT. Although, we still want to let the guest
using CNTFRQ in normal case. After all, the property "clock-frequency"
is just a workaround for buggy firmware.
Also add a stub for fdt_property_u32 which is not present in libfdt <

binutils 2.22 changed ld default from --copy-dt-needed-entries
to -no-copy-dt-needed-entries. This revealed that some objects
are linked implicitly with libtinfo and newer ld fails to build
relevant executables.
Below is short explanation why we should not do that...
http://fedoraproject.org/wiki/UnderstandingDSOLinkChange says:
The default behaviour for ld (my note: before version 2.22) allows
users to 'indirectly' link to required objects/libraries through
intermediate objects/libraries. While this is convenient, it can
also be dangerous because it makes your program's dependencies tied
to the dependencies of other objects. If those objects ever change
their linkages, they can break your program without any changes
to your own code!

Allow the user to pass additional nodes to the guest device tree. For
this purpose, everything in the node /passthrough from the partial
device tree will be copied into the guest device tree.
The node /aliases will be also copied to allow the user to define
aliases which can be used by the guest kernel.
A simple partial device tree will look like:
/dts-v1/;
/ {
#address-cells = <2>;
#size-cells = <2>;
passthrough {
compatible = "simple-bus";
ranges;
#address-cells = <2>;
#size-cells = <2>;
/* List of your nodes */
}
};
Note that:
* The interrupt-parent property will be added by the toolstack in
the root node
* The properties compatible, ranges, #address-cells and #size-cells
in /passthrough are mandatory.
The helpers provided by the libfdt don't perform all the necessary
security check on a given device tree. Therefore, only trusted device
tree should be used.
Note: The partial device tree code requires the presence of libfdt
functions which have been only correctly exported in libfdt 1.4.0 and
higher. All the major distributions but Debian Wheezy are using v1.4.0
or higher. It has been decided to disable partial device tree support on
OSes where libfdt doesn't meet the requirement.

Some systems have python-config include -D_FORTIFY_SOURCE in the
CFLAGS. But -D_FORTIFY_SOURCE does not (currently) work with -O0, and
-O0 is enabled in debug builds (since 1166ecf781). As a result, on
those systems, debug builds fail.
Work around this problem as follows:
* In configure, detect -D_FORTIFY_SOURCE in $(python-config --cflags)
* If detected, set the new autoconf substitution and make variable
PY_NOOPT_CFLAGS to -O1.
* In tools/Rules.mk, where we add -O0, also add PY_NOOPT_CFLAGS
(which will override the -O0 with -O1 if required).
Overriding the -O0 is better than disabling Fortify because the
latter might have an adverse security impact. A user who wants to
disable optimisation completely even for Python and also disable
Fortify can set the environment variable
EXTRA_CFLAGS_XEN_TOOLS='-U_FORTIFY_SOURCE -O0'
