Juergen Gross 976ce01e10 tools: remove systemd xenstore socket definitions
On a system with systemd the xenstore sockets are created via systemd.
Remove the related configuration files in order to be able to decide
at runtime whether the sockets should be created or not. This will
enable Xen to start xenstore either via a daemon or via a stub domain.

As the xenstore domain start program will exit after it has done its
job prepare the same behaviour to be tolerated by systemd for the
xenstore daemon by specifying the appropriate flags in the service
file.

A rerun of autogen.sh is required.

Rusty Bird 4f7e0d54a5 tools/hotplug: Add native systemd xendriverdomain.service
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"

(Please rerun autogen.sh after applying this patch)

George Dunlap 16181cbb10 tools: Honor Config.mk debug value, rather than setting our own
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
into place naturally.

Ian Campbell 2909ad4c96 tools/hotplug: Add an initscript to start "xl devd" in a driver domain
The removal of the udev rules highlighted that although it has been
replaced by "xl devd" there isn't an initscript to replace it.

To enable this add a --pidfile option to xl devd.

Tested on Linux by running the script in dom0 and checking the daemon
was started/stopped, but not in an actual driver domain environment
since I don't have one conveniently available. I also checked that
running without the --pidfile option still works.

Scripts mainly cribbed from the xencommons for each platform.

George Dunlap 2ba368d138 libxl: Remove linux udev rules
They are no longer needed, having been replaced by a daemon for
driverdomains which will run scripts as necessary.

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.

Rather than try to sort out that issue, just remove them entirely.

Julien Grall 59ccb33c40 xen/arm: Propagate clock-frequency to DOMU if present in the DT timer node
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 <
1.4.0 used by distribution such as Debian Wheezy.

Daniel Kiper b248d32f4f tools: link executables with libtinfo explicitly
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!

Julien Grall 51c2d7bd4d tools/(lib)xl: Add partial device tree support for ARM
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.

Ian Jackson 0013245473 tools: work around collision of -O0 and -D_FORTIFY_SOURCE
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'

Olaf Hering d30c14b1f1 tools/hotplug: use XEN_SCRIPT_DIR instead of hardcoded path
Helper scripts get installed into XEN_SCRIPT_DIR, but initscripts,
helper scripts and udev rules still refer to the hardcoded location
/etc/xen/scripts/. Update scripts, rules and Makefile to refer to
@XEN_SCRIPT_DIR@ instead.

Update configure.ac to substitute the path in files using
XEN_SCRIPT_DIR. Remove XEN_SCRIPT_DIR from StdGNU.mk and SunOS.mk, its
already in Paths.mk.

Note: In SunOS.mk it refered to PRIVATE_PREFIX, which was introduced by
9f6d07bac9 ("tools: get rid of hardcoded
config dirs").

Yang Hongyang 622e837570 autoconf: add libnl3 dependency for Remus network buffering support
Libnl3 is required for controlling Remus network buffering.
This patch adds dependency on libnl3 (>= 3.2.8) to autoconf scripts.
It also provides the ability to configure tools without libnl3 support
i.e., without network buffering support.

When there is no network buffering support, libxl__netbuffer_enabled()
returns 0, otherwise returns 1. The callers of this api will be
introduced in the rest of the series.

NOTE: This patch changes tools/configure.ac, please rerun
      autogen.sh while applying the patch.

Stefano Stabellini e9d6c685b1 tools: enable QEMU for ARM builds
Build qemu-xen on ARM and ARM64: it is used to provide the PV backends,
disk and framebuffer in particular.

Ideally we would also modify the configure options to only build what is
necessary: a machine just for PV backends. However that is a work in
progress and not yet available in QEMU (see
http://marc.info/?l=qemu-devel&m=139082425718379&w=2). So we just build
the usual i386 target, even though no i386 emulation is going to be done
by qemu-xen on ARM.

Luis R. Rodriguez 015330004e systemd: add xen systemd service and module files
This adds the systemd xen service / module files and integrates
support into the build system.

This goes in with AX_AVAILABLE_SYSTEMD() which will enable
systemd if development libraries have been found on your
build system. If you don't have systemd on target systems
for binaries built with systemd then the binary will not
work, you must explicitly disable systemd support if you
do not want to build systemd support.

When systemd libraries are present only systems that
have booted into systemd go through the systemd initialization,
otherwise the SysVinit is used.

These are originally based on the Fedora systemd files.

Changes made from Fedora's systemd files:

  * split sockets into two files to claim different permissions
  * Use /bin/sh -c exec to for a simple launcher implementation
  * enables systemd socket activation for C xenstored and Ocaml
    oxenstored
  * use sd_notify(), so change the service to Type=notify, because of
    this we remove the PIDFile specification as we don't care for it, and let
    systemd do its magic for us, this also means we don't have to fork
    so we use --no-fork with systemd
  * defines a modules-load.d, its original source file will be shared
    between systemd and old init systems
  * simplify service files with ConditionVirtualization=xen which uses
    the built in systemd virtualization backend detection, these
    service files will not be available to start on systems that do not
    boot with xen as a hypervisor
  * use autoconf to replace @variable@ paths for us which piggy
    backs on top of the latest autoconf changes to xen
  * removes oxenstored service file in favor of a system variable which
    controls which which xentored to use at run time, we avoid multiple
    service files this way.
  * simplifies startup to not require polling on the sockets
    as initial socket management is handled by systemd, we just
    take on the socket later once anything pokes at it, a simple nc -U
    (as root) on any of the sockets files can activate the service for example.
    Anything queued up will be sent to us once we start. Socket activation
    should in theory also let us dynamically switch between xenstores but more
    importantly we could upgrade xenstored while keeping all active
    socket communication queued up, but in order to take advantage of
    this we eventually would need to remove the requirement of not being
    able to bring down the xenstored. Even though active sockets are
    supported since most libxl communication doesn't triggger a check
    on the unix socket first administrators are encouraged to enable
    the xenstored.service to triggger an initialization of the xenstored
    upon bring up. Some systems also never use unix sockets for
    communication with the xenstored and as such active sockets will
    not be used there.
  * allow for xenstored configuration through *either* of these
    configuration files:
	- /etc/sysconfig/xenstored
	- /etc/default/xenstored
    The /etc/default/xenstored will let debian based systems do
    the same, while SUSE/OpenSUSE/Fedora/RedHat can keep on chugging
    with sysconfig. We leave these files all commented out by default
    though given that for systemd we want to encourage not using them.
  * ensures we create the run directory as most systems will likely
    be using a tmpfs for run dirs for the pid files
  * Some systems define the selinux context in the systemd Option for the
    /var/lib/xenstored tmpfs:
	Options=mode=755,context="system_u:object_r:xenstored_var_lib_t:s0"
    For the upstream version we remove that and let systems specify the
    context on their system /etc/default/xenstored or /etc/sysconfig/xenstored
    $XENSTORED_MOUNT_CTX variable, with a default to none.
  * takes advantage of the shared xendomains helper for the xendomains
    service
  * Add the new dom0 that gets kicked off for disk backend access into
    its own systemd service associated to xen

We end up with these systemd files:

General requirements:

  * proc-xen.mount
  * var-lib-xenstored.mount

xenstored:

  * xenstored.service
  * xenstored.socket
  * xenstored_ro.socket
  * xenconsoled.service
  * xen-qemu-dom0-disk-backend.service.in

Optional:

  * xendomains.service
  * xen-watchdog.service

As for integration with xen, we house keep all the systemd files
under a new directory tools/hotplug/Linux/systemd/ and will be targeted
by default when building on Linux systems if systemd development
libraries are present at build time.

The systemd files will be sanitized for meta @VARIABLES@ upon
configuration and installed upon the install target. Systems that
do not use systemd can still get systemd service unit files installed
if the build system enabled systemd support, this however does not
mandate a requirement of having systemd libraries present. Old init
scripts are always installed.

If you don't specify a prefix you will end up with the services
files under /usr/local/lib/systemd/system/ by default, and systemd
modules-load.d conf files under /usr/local/lib/modules-load.d/ which
systemd does look for (although it seems this is not documented).

Distributions are expected to provide their /usr/ prefix to end up in
the more generic location upon distribution install at
/usr/lib/systemd/system/ and /usr/lib/modules-load.d/ respectively.

Luis R. Rodriguez dff4c31163 autoconf: xen: enable explicit preference option for xenstored preference
As it stands oxenstored will be used by default if ocaml tools are
found, the init system will also try to use oxenstored first if its
found otherwise the cxenstored will be used. Lets simplify the init
script and let users be explicit about the preference through configure.

This adds support to let you be explicit about the xenstored preference,
you can only use one of these two options:

./configure --with-xenstored=xenstored
./configure --with-xenstored=oxenstored

We continue with the old behaviour and default oxenstored will be used
but only if you have ocaml dependencies. Since the xenstored preference
is explicit now and since we require configure substitutions for it we
make use of the AX_XEN_EXPAND_CONFIG() helpers as otherwise substitution
for SBINDIR is not propagated from the top level configuration.

All this allows us to simplify the init script to use the configured
xenstore from the start. We update the sysconfig/default xencommons file
with the paths for the different options though, this can be used by
users to override the default xenstored, this follows the old behaviour
but we now just explicitly provide the full configured paths for users.

As before, changing the xenstore requires a reboot.

In order to help with documentation we update the README with some
details on configure usage refer to the wiki [0] [1] [2] for more elaborate
details.

Since we are now parsing an entry within Paths.mk.in on tools we let
the move the parsing of the file to be the tool's configure.

Ian Jackson 69ba39ec05 rump kernels: Handle rumpxen host in configure
Support
   ./configure --host=x86_64-rumpxen-netbsd
   ./configure --host=i386-rumpxen-netbsd

Setting --host tells configure we are cross compiling and therefore
has various automatic effects.

But in this patch we make some deliberate changes as well:
 * We disable a large number of configure tests for libraries
   etc. which don't exist.
 * We set CONFIG_RUMP in Tools.mk.
 * Hence, we automatically set XEN_OS.

(I have only tested the 32-bit build but I think the 64-bit build
should work just as well.)

Reference:
  http://valgrind.org/docs/manual/mc-manual.html#mc-manual.clientreqs

Client requests are safe to compile into code for running outside of
valgrind.  Therefore, enable client requests whenever autoconf can find
memcheck.h and debug builds are enabled.
