The "install" rules depends on both "all" and "subdirs-install" and
"all" depends on "subdirs-all". This leads the "install" rules to call
both "subdirs-all" and "subdirs-install" which create a race with two
concurrent `make` within the same directory (systemd) trying to make the
same things (xen.conf) and failing.
Ultimatly, "install" should only depend on the things it needs to
install, and not on "all".

This replaces config/Linux.modules with a configure option. As a result
of this change only a single xencomons.in is required, instead of a
xencomons.in.in and sed hackery.
After this change blktap2 and blktap will be loaded at the same time.
This is already done in out-of-tree xencommons scripts, and systemd will
load both modules as well. No harm is expected by loading both modules.

[ ijc -- ran autogen.sh as requested ]
The current usage of LIBEXEC is bogus. It describes the directory for
private xen executables. Other places create their own, similar
libexecdir path as $prefix/lib/xen/*.
Additional two other variables are used to describe similar paths:
PRIVATE_BINDIR and PRIVATE_PREFIX
The autoconf documentation refers to libexec as a directory for
executables and stuff which is called by other programs, not by the
user.
Adjust all places that want libexecdir as a target path. LIBEXEC refers
now to the base directory. Three convenience variables are used to refer
to paths to private binaries, libs and include files.
In the systemd files LIBEXEC_BIN is substituted, so this variable has to
be present in autoconf. All other variables are expanded in Paths.mk
because they are only used in Makefiles.
Most users of LIBEXEC are updated to use LIBEXEC_BIN because that is
what they want.
Users of PRIVATE_BINDIR are updated to use LIBEXEC_BIN because that is
what they want. PRIVATE_BINDIR and PRIVATE_PREFIX usage is removed by
this patch, in favour of LIBXEC_BIN and LIBEXEC
An internal libxl function was removed. A single helper to retrieve
LIBEXEC_BIN remains.
As suggested by the autoconf documentation, configure appends the
package name to LIBEXEC to make sure the provided directory really
refers to xen. This makes sure "make uninstall" preserves the real
libexecdir.

This patch adds the machinery required for protecting a guest's
disk state, when the guest disk uses a DRBD disk backend.
This patch comprises of two parts:
1. Hotplug scripts: The block-drbd-probe script is responsible for
performing sanity checks on the state of the DRBD disk before the
checkpointing process begins. This script should be invoked by
libxl for each of the guest's disk devices, when starting Remus.
2. Remus drbd disk device: Implements the interfaces required by the
remus abstract device layer. A note about the implementation:
a) setup() is called for each disk attached to the guest.
During setup():
i) The hotplug script is called to perform the sanity check.
ii) Libxl obtains a handle to the DRBD device (/dev/drbd*) and
and subsequently controls disk checkpoint replication using
this handle in the checkpoint callbacks.
c) The preresume() checkpoint callback is executed asynchronously
using libxl__ev_child_fork(), as it may potentially block for more
than few seconds in case of backup failure.

This patch adds the machinery required for protecting a guest's
network device state. This patch comprises of two parts:
1. Hotplug scripts: The remus-netbuf-setup script is responsible for
setting up and tearing down the necessary infrastructure required for
network output buffering. This script should be invoked by libxl for
each of the guest's network interfaces, when starting or stopping Remus.
Apart from returning success/failure indication via the usual hotplug
entries in xenstore, this script also writes to xenstore, the name of
the REMUS_IFB device to be used to control the vif's network output.
The script relies on libnl3 command line utilities to perform various
setup/teardown functions. The script is confined to Linux platforms only
since NetBSD does not seem to have libnl3.
2. Remus network device: Implements the interfaces required by the
remus abstract device layer. A note about the implementation:
a) init_subkind_nic() & cleanup_subkind_nic() are called once per Remus
invocation. They establish and free netlink related state respectively.
b) setup() and teardown are called for each vif attached to the
guest.
During setup():
i) The hotplug script is called to setup a network buffer on a
given vif. The script chooses an available IFB device from
the system, redirects vif egress traffic to the IFB device
and sets up the plug qdisc (output buffer) on the IFB device.
The name of the IFB device is communicated via xenstore to
libxl.
ii) Libxl obtains a handle to the plug qdisc using the libnl3 API
and subsequently controls output buffering using this handle
in the checkpoint callbacks.
During teardown(), the hotplug scripts are called again to remove
the vif->ifb traffic redirection, release the ifb and the plug
qdisc associated with it.
c) The checkpoint callbacks [postsuspend(), preresume() and commit()]
are implemented as synchronous ops as the netlink calls associated
with the qdisc subsystem are very fast.

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.

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.

When a HVM guest is shutdown some of the 'remove' events can not claim
the lock for some reason. Instead they try to grab the lock in a busy
loop, until udev reaps the xen-hotplug-cleanup helper.
After analyzing the resulting logfile its not obvious what the cause is.
The only explanation is that bash (?) gets confused if the same lockfd
is opened again and again. Closing it in each iteration seem to fix the
issue.
This was observed with sles11sp2 (bash 3.2) and 4.2 xend.
