900383f5b8 make: skip pdwtags when building with CLang
When building with CLang the structs that are emitted by pdwtags appear
in a completely different order than with GCC, which causes the
comparison against expected data to fail.

Ideally the test would not be sensitive to the ordering, because even
future GCC could cause changes, but that's not easy to fix. So for now
just skip the test when using clang.

e1ab81b339 storage: fix sheepdog driver / test linking to avoid duplicating source
The libvirt_storage_backend_sheepdog_priv.la library depends on symbols
provided in the libvirt_driver_storage_impl.la library. As such the
latter must be listed 2nd when passed to the linker to avoid symbol
resolution problems. This mistake is being masked by the sheepdog
driver linking in a second copy of the storage driver code. Remove
this duplicate linkage of backend source and fix the test link order.

A typo in the uninstall-data-extra rule expansion meant we just called
the install rule again, instead of the uninstall rule. While fixing
this, just inline the dependancy, since the intermediate
install-data-extra rule adds no value.

a1f6030def build: passing the "-z defs" linker flag to prevent undefined symbols
Undefined symbols are a bad thing in general because they can get
resolved in unexpected ways at runtime if multiple sources provide the
same symbol name. For example both glibc and libtirpc may provide XDR
symbols and we want to ensure that we resolve to libtirpc if that's what
we originally built against.

The toolchain maintainers thus strongly recommend that all applications
use the '-z defs' linker flag to prevent undefined symbols. This is
shortly becoming part of the default linker flags for RPMs. As an added
benefit this aligns Linux builds with Windows builds, where the linker
has never permitted undefined symbols.

21639744f6 build: explicitly link all modules with libvirt.so
The dlopened modules we currently build all use various symbols from
libvirt.so, but don't actually link to it. They rely on the libvirtd
daemon re-exporting the libvirt.so symbols. This means that at the
time the modules are linked, they contain a huge number of undefined
symbols. It also means that these undefined symbols are not versioned,
so despite us providing a LIBVIRT_PRIVATE_XXXX version that
intentionally changes on every release, the loadable modules could
actually be loaded into any libvirtd regardless of version.

This change explicitly links all modules against libvirt.so so
that they don't rely on the re-export behave and can be fully resolved
at build time. This will give us a stronger guarantee modules will
actually be loadable at runtime and that we're using modules from the
matched build.

c3b24e7051 rpc: don't link in second copy of RPC code to libvirtd & lockd plugin
The libvirt_driver_remote.la static library is linked into the
libvirt.so dynamic library, providing both the generic RPC layer code
and the remote protocol client driver. The libvirtd daemon the itself
links to libvirt_driver_remote.la, in order to get access to the generic
RPC layer code and the XDR functions for the remote driver. This means
we get multiple copies of the same code in libvirtd, one direct and one
indirect via libvirt.so. The same mistake affects the lockd plugin.

The libvirtd daemon should instead just link aganist the generic RPC
layer code that's in libvirt.so. This is easily doable if we add exports
for the few symbols we've previously missed, and wildcard export xdr_*
to expose the auto-generated XDR marshallers.

064fec69be storage: move storage file backend framework into util directory
The QEMU driver loadable module needs to be able to resolve all ELF
symbols it references against libvirt.so. Some of its symbols can only
be resolved against the storage_driver.so loadable module which creates
a hard dependancy between them. By moving the storage file backend
framework into the util directory, this gets included directly in the
libvirt.so library. The actual backend implementations are still done as
loadable modules, so this doesn't re-add deps on gluster libraries.

no reason for 'update' not being part of the module as well. This also

This patch also drops the node_device_linux_sysfs module from the repo
since:
a) it only contained the capability handlers we just moved
b) it's only linked with the driver (by design) and thus unreachable to
other modules
c) we touch sysfs across all the src/util modules so the module being

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.

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*

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.

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.

(older) systems don't advertise their hostname in DHCP
transactions at all.
In cases like that it would be helpful if we translate domain
name as seen by libvirt too so that users can:

  # virsh start $dom && ssh $dom

while older libvirt module maintains its current behaviour (that

Rather than add yet another $(CYGWIN_EXTRA_LDFLAGS) to all the
impacted *_la_LDFLAGS, it was easier to just pull the extra
flags into ALL libraries via AM_LDFLAGS.

Then, fix lockd_la_LDFLAGS to include AM_LDFLAGS, like all other
libraries.

01163b1b1f bhyve: implement virConnectDomainXMLFromNative
First, remove escaped newlines and split up the string into an argv-list for
the bhyve and loader commands, respectively. This is done by iterating over the
string splitting it by newlines, and then re-iterating over each line,
splitting it by spaces.

Since this code reuses part of the code of qemu_parse_command.c
(in bhyveCommandLine2argv), add the appropriate copyright notices.

1eca5f6581 secret: Move virStorageSecretType and rename
Move the enum into a new src/util/virsecret.h, rename it to be
virSecretLookupType. Add a src/util/virsecret.h in order to perform
a couple of simple operations on the secret XML and virSecretLookupTypeDef
for clearing and copying.

This includes quite a bit of collateral damage, but the goal is to remove
the "virStorage*" and replace with the virSecretLookupType so that it's
easier to to add new lookups that aren't necessarily storage pool related.

53d98ccea7 xenconfig: support bios=ovmf xl.cfg
Add support to xenconfig for conversion of xl.cfg(5) bios config
to/from libvirt domXml <loader> config. SeaBIOS is the default
for HVM guests using upstream QEMU. ROMBIOS is the default when
using the old qemu-dm. This patch allows specifying OVMF as an
alternate firmware.

Example xl.cfg:
  bios = "ovmf"

Example domXML:
  <os>
    ...
    <loader readonly='yes' type='pflash'>/usr/lib/xen/boot/ovmf.bin</loader>
  </os>

Note that currently Xen does not support a separate nvram for
non-volatile variables.

c0bc172383 systemd: directly notify systemd instead of using sd_notify
The sd_notify method is used to tell systemd when libvirtd
has finished starting up. All it does is send a datagram
containing the string parameter to systemd on a UNIX socket
named in the NOTIFY_SOCKET environment variable. Rather than
pulling in the systemd libraries for this, just code the
notification directly in libvirt as this is a stable ABI
from systemd's POV which explicitly allows independant
implementations:

4652b158aa secret: Create virsecretobj.c and virsecretconf.h
Move virSecretObj from secret_driver.c to virsecretobj.h

To support being able to create a hashed secrets list, move the
virSecretObj to virsecretobj.h so that the code can at least find
the definition.

This should be a temporary situation while the virsecretobj.c code
is patched in order to support a hashed secret object while still
having the linked list support in secret_driver.c. Eventually, the
goal is to move the virSecretObj into virsecretobj.c, although it
is notable that the existing model from which virSecretObj was
derived has virDomainObj in src/conf/domain_conf.h and virNetworkObj
in src/conf/network_conf.h, so virSecretObj wouldn't be unique if
it were to remain in virsecretobj.h  Still adding accessors to fetch
and store hashed object data will be the end goal.

Add definitions and infrastucture in virsecretobj.c to create and
handle a hashed virSecretObj and virSecretObjList including the class,
object, lock setup, and disposal API's. Nothing will call these yet.

This infrastructure will replace the forward linked list logic
within the secret_driver, eventually.
