0eda09f490 vbox: Add support for 5.2.x
Simply add the 5.2 SDK header to the existing unified framework. No
other special handling is needed as there's no API break between
existing 5.1 and the just added 5.2.

3e7db8d3e8 Remove backslash alignment attempts
Right-aligning backslashes when defining macros or using complex
commands in Makefiles looks cute, but as soon as any changes is
required to the code you end up with either distractingly broken
alignment or unnecessarily big diffs where most of the changes
are just pushing all backslashes a few characters to one side.

6c200c76f1 build: isolate core libvirt libs deps from xen runtime
Generating libvirt packages per make rpm, "with-libxl=1" and "with-xen=1",
adds strict runtime dependencies per libxenlight for xen-libs package from
core libvirt-libs package.  This is not necessary and unfortunate since
those dependencies set demand to "xen-libs" package even when there's no
need for libvirt xen or libxl driver components.

This patch is to have two separate xenconfig lib tool libraries: one for
core libvirt (without XL), and a another that contains xl for libxl driver
(libvirt_driver_libxl_impl.la) which when loading the driver, loads the
remaining symbols (xen{Format,Parse}XL. For the user/sysadmin, this means
the xen dependencies are moved into libxl driver, instead of core libvirt.

6cf7fc573f security: apparmor: load the storage driver dynamically
In commit 5e515b542d I've attempted to fix the inability to access
storage from the apparmor helper program by linking with the storage
driver. By linking with the .so the linker complains that it's not
portable. Fix this by loading the module dynamically as we are supposed

The cached data must be an instance of virObject.

5e515b542d security: apparmor: Properly link with storage driver in helper program
The refactor to split up storage driver into modules broke the apparmor
helper program, since that did not initialize the storage driver
properly and thus detection of the backing chain could not work.

Register the storage driver backends explicitly. Unfortunately it's now
necessary to link with the full storage driver to satisfy dependencies
of the loadable modules.

02fb15fb60 util: switch over to use keycodemapdb GIT submodule
A long time ago we imported the keymaps.csv file from GTK-VNC so we
can do conversions between keycode sets. Meanwhile lots of bug fixes
have gone into this CSV file and libvirt hasn't kept in sync. The
keymaps.csv file and associated generator script has been pulled out
of GTK-VNC into a dedicated GIT repo for use as a submodule. This
allows GTK-VNC, SPICE-GTK, QEMU and libvirt to share the same master
database and tools and pushing updates merely requires a submodule
commit update as with gnulib.

The test suite is updated to cover some extra boundary conditions.

3372f8fb5b hyperv: add support for Hyper-V 2012 and newer
This patch reworks the Hyper-V driver structs and the code generator
to provide seamless support for both Hyper-V 2008 and 2012 or newer.
This does not implement any new libvirt APIs, it just adapts existing
2008-only driver to also handle 2012 and newer by sharing as much
driver code as possible (currently it's all of it :-)). This is needed
to set the foundation before we can move forward with implementing the
rest of the driver APIs.

With the 2012 release, Microsoft introduced "v2" version of Msvm_* WMI
classes. Those are largely the same as "v1" (used in 2008) but have some
new properties as well as need different wsman request URIs. To
accomodate those differences, most of work went into the code generator
so that it's "aware" of possibility of multiple versions of the same WMI
class and produce C code accordingly.

To accomplish this the following changes were made:

 * the abstract hypervObject struct's data member was changed to a union
   that has "common", "v1" and "v2" members. Those are structs that
   represent WMI classes that we get back from wsman response. The
   "common" struct has members that are present in both "v1" and "v2"
   which the driver API callbacks can use to read the data from in
   version-independent manner (if version-specific member needs to be
   accessed the driver can check priv->wmiVersion and read from "v1" or
   "v2" as needed). Those structs are guaranteed to be  memory aligned
   by the code generator (see the align_property_members implementation
   that takes care of that)
 * the generator produces *_WmiInfo for each WMI class "family" that
   holds an array of hypervWmiClassInfoPtr each providing information
   as to which request URI to use for each "version" of given WMI class
   as well as XmlSerializerInfo struct needed to unserilize WS-MAN
   responsed into the data structs. The driver uses those to make proper
   WS-MAN request depending on which version it's connected to.
 * the generator no longer produces "helper" functions such as
   hypervGetMsvmComputerSystemList as those were originally just simple
   wrappers around hypervEnumAndPull, instead those were hand-written
   now (to keep driver changes minimal). The reason is that we'll have
   more code coming implementing missing libvirt APIs and surely code
   patterns will emerge that would warrant more useful "utility" functions
   like that.
 * a hypervInitConnection was added to the driver which "detects"
   Hyper-V version by testing simple wsman request using v2 then falling
   back to v1, obviously if both fail, the we're erroring out.

To express how the above translates in code:

void
hypervImplementSomeLibvirtApi(virConnectPtr conn, ...)
{
    hypervPrivate *priv = conn->privateData;
    virBuffer query = VIR_BUFFER_INITIALIZER;
    hypervWqlQuery wqlQuery = HYPERV_WQL_QUERY_INITIALIZER;
    Msvm_ComputerSystem *list = NULL; /* typed hypervObject instance */

    /* the WmiInfo struct has the data needed for wsman request and
     * response handling for both v1 and v2 */
    wqlQuery.info = Msvm_ComputerSystem_WmiInfo;
    wqlQuery.query = &query;

    virBufferAddLit(&query, "select * from Msvm_ComputerSystem");

    if (hypervEnumAndPull(priv, &wqlQuery, (hypervObject **) &list) < 0) {
        goto cleanup;
    }

    if (list == NULL) {
        /* none found */
        goto cleanup;
    }

    /* works with v1 and v2 */
    char *vmName = list->data.common->Name;

    /* access property that is in v2 only */
    if (priv->wmiVersion == HYPERV_WMI_VERSION_V2)
        char *foo = list->data.v2->V2Property;
    else
        char *foo = list->data.v1->V1Property;

 cleanup:
    hypervFreeObject(priv, (hypervObject *)list);
}

26ae4e482a Remove src/nodeinfo
There is no "node driver" as there was before, drivers have to do
their own ACL checking anyway, so they all specify their functions and
nodeinfo is basically just extending conf/capablities.  Hence moving
the code to src/conf/ is the right way to go.

Also that way we can de-duplicate some code that is in virsysfs and/or
virhostcpu that got duplicated during the virhostcpu.c split.  And
Some cleanup is done throughout the changes, like adding the vir*
prefix etc.

dbad8f8aee qemu: block: Add code to allow detection of auto-allocated node names
qemu for some time already sets node names automatically for the block
nodes. This patch adds code that attempts a best-effort detection of the
node names for the backing chain from the output of
'query-named-block-nodes'. The only drawback is that the data provided
by qemu needs to be matched by the filename as seen by qemu and thus
if two disks share a single backing store file the detection won't work.

This will allow us to use qemu commands such as
'block-set-write-threshold' which only accepts node names.

In this patch only the detection code is added, it will be used later.

eadaa97548 qemu: Enter the namespace on relabelling
Instead of trying to fix our security drivers, we can use a
simple trick to relabel paths in both namespace and the host.
I mean, if we enter the namespace some paths are still shared
with the host so any change done to them is visible from the host
too.
Therefore, we can just enter the namespace and call
SetAllLabel()/RestoreAllLabel() from there. Yes, it has slight
overhead because we have to fork in order to enter the namespace.
But on the other hand, no complexity is added to our code.
