Having a daemon/ directory makes little sense from a code structure
point of view, as 90% of the code that is built into libvirtd already
lives in the src/ directory. The virtlockd and virlogd daemons also live
entirely in src/{locking,logging} directories. This moves the source
code for libvirtd into src/remote/, alongside the client code.

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.

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.

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

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.

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

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.

Rather than add yet another $(CYGWIN_EXTRA_LDFLAGS) to all the

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.

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.

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.

The virQEMUDriverConfig object contains lists of
loader:nvram pairs to advertise firmwares supported by

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

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.
The current rule fails if the target already exists:
cd /home/jenkins/build/libvirt/lib && \
ln -s libnss_libvirt.so.1 nss_libvirt.so.1
ln: nss_libvirt.so.1: File exists
Makefile:3357: recipe for target 'install-exec-hook' failed
However, all other rules concerned with installation are
idempotent and will happily overwrite an existing target,
so this one should as well.

We currently blindly accept any numeric value as a GIC version, even
though only GIC v2 and GIC v3 actually exist; on the other hand, we
reject "host", which is a perfectly legitimate value for QEMU guests.
This new enumeration contains all GIC versions libvirt is aware of.
Extract out the qemuParseCommandLine{String|Pid} into their own
separate module - taking with it all the various static functions.
Causes a ripple effect with a few other modules to include the
new qemu_parse_command.h.
Narrowed down the list of #include's in the split out module to
those that are necessary for build.
The current code was a little bit odd. At first we've removed all
possible implicit input devices from domain definition to add them later
back if there was any graphics device defined while parsing XML
description. That's not all, while formating domain definition to XML
description we at first ignore any input devices with bus different to
USB and VIRTIO and few lines later we add implicit input devices to XML.
This seems to me as a lot of code for nothing. This patch may look
to be more complicated than original approach, but this is a preferred
way to modify/add driver specific stuff only in those drivers and not
deal with them in common parsing/formating functions.
The update is to add those implicit input devices into config XML to
follow the real HW configuration visible by guest OS.
There was also inconsistence between our behavior and QEMU's in the way,
that in QEMU there is no way how to disable those implicit input devices
for x86 architecture and they are available always, even without graphics
device. This applies also to XEN hypervisor. VZ driver already does its
part by putting correct implicit devices into live XML.

That happens because without any specific options gcc doesn't keep enum
information in the resulting binary object. I managed to isolate the
parameters of gcc that caused this issue to disappear, however I
remember that they influenced the resulting binaries quite a bit and
were definitely not something we would want to add as mandatory to the
build process.
So to deal with this cleanly, let's take that enum and separate it out
to its own header file. Since it is only used in the lockd driver and
the protocol, lock_driver_lockd.h feels like a suitable name.

The parameter --disable-dependency-tracking is supposed to speed up
one-time build due to the fact that it disables some dependency
extractors that, apparently, take longer time to execute. That is a
problem for code that is generated into builddir (especially some
specific subdirectory) because the directory it should be installed to
does not exists in VPATH and without the dependency tracking is not
created. Generating such file hence fails with -ENOENT. In order to
keep generating files into builddir instead of srcdir, we must create
the directory ourselves. This should finally fix the problem that is
being fixed multiple times since its introduction in commit a9fe620372
and let us continue with cleaning those parts of Makefiles that depend
on generating files into the srcdir rather than builddir as it should
be.
