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.

Rather than static linking in various of the helper libraries to
libvirt_lxc, just link against the main libvirt.so. This is more memory
and time efficient because it will already be cached in memory and
sharable between processes.
CAPNG flags need adding because the LXC code directly calls various
libcapng APIs and no longer inherits the CAPNG flags via the statically
linked .a libs.

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.

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.

Generating libvirt packages per make rpm, "with-libxl=1" and "with-xen=1",
adds strict runtime dependencies per libxenlight for xen-libs package from

those dependencies set demand to "xen-libs" package even when there's no

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

Move all the virNetworkObj related API/data structures into their own
modules virnetworkobj.{c,h} from the network_conf.{c,h}
Purely code motion at this point plus adjustments to cleanly build
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);
}
Introduce STRICT_FRAME_LIMIT_CFLAGS that will be used for
production code and RELAXED_FRAME_LIMIT_CFLAGS for tests.
Raising the limit for tests allows building them with clang
with optimizations disabled.
Beside creation, disposal, getter, and setter methods the module exports
methods to work with lists of mediated devices.

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.

If driver modules are enabled turn storage driver backends into

rpm based distros will at this point install all the backends when

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.

the lists, all of which is useful for other drivers too.
To avoid code duplication, introduce a virFirmware object
to encapsulate firmware details and switch the qemu driver
to use it.

Add the virDomainLxcEnterCGroup API to the libvirt-lxc.so
file. This method moves the calling process into the cgroups
associated with the container.

We need to use the gnutls_priority_set_direct method which
was not introduced until 2.1.7, so bump version to 2.2.0
which is the first stable release with it included. This
release dates from Dec 2007 so it is reasonable to ditch
support for the 1.x.x series for gnutls releases entirely.

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:
See "Reimplementable Independently" column in the
"$NOTIFY_SOCKET Daemon Notifications" row:

Move the module from qemu_command.c to a new module virqemu.c and
rename the API to virQEMUBuildObjectCommandline.
This API will then be shareable with qemu-img and the need to build
a security object for luks support.

We need to append GNUTLS_CFLAGS while building utils because virtcrypto
is using it. This fixes build on freebsd where gnutuls is in
/usr/local/include.

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.
We can't use eg. @sysconfdir@ directly in the .pod file, because
pod2man(1) will interpret that as a variable name and format it
accordingly.
Instead, we use eg. SYSCONFDIR and use a subsequent sed(1) call
to turn it into the expected @sysconfdir@.
After this commit, all man pages are generated using the same two
steps:
1. Process a source $command.pod file with pod2man(1) to obtain
a valid man page in $command.$section.in
2. Process $command.$section.in with sed(1) to obtain the final
man page in $command.$section
FreeBSD's sed(1) doesn't support using "\n" to insert a newline,
so the installed default.xml file ends up containing a literal
"n" between tags; to work around this problem, add a tr(1)
invocation as suggested by the sed FAQ[1].

According to the autoconf manual, using '$(LN_S) -f' is not
portable; remove the target explicitly beforehand to work around
this limitation.
Adjust some slightly awkward indentation while at it.
