For a few cases where we handle secret information it's good to clear
the buffers containing sensitive data before freeing them.
Introduce VIR_DISPOSE, VIR_DISPOSE_N and VIR_DISPOSE_STRING that allow

This script will check output generated by virtestmock against a

far, the white list is rather sparse at the moment.
This test should be ran only after all other tests finished, and
should cleanup the temporary file before their execution. Because

There is some magic going on when it comes to stat() or lstat().
Basically, stat() can either be a regular function, an inline
function that calls __xstat(_STAT_VER, ...) or a macro that does
the same as the inline func. Don't ask why is that, just read the
documentation in sys/stat.h and make sure you have a bucket next
to you. Anyway, currently there will not be both stat and __xstat
symbols at the same time, as one of them gets overwritten to the
other one during compilation. But this is not true anymore once
we start chaining our mocking libraries. Therefore we need a
wrapper that calls desired function from glibc.

Some of the test configuration files in tests/xlconfigdata
use the old qemu-dm as the emulator. Many of the configuration
features tested (spice, rbd, multi-usb) are not even usable with
the old qemu. Change these files to use the new qemu-xen (also
known as qemu upstream) emulator.
Note: This change fixes xlconfigtest failures when the old
qemu is actually installed on the system. During device post
parse, the libxl driver attempts to invoke the emulator to
determine if it is the old or new qemu so it can properly set
video RAM defaults. With the old qemu installed, the default
video RAM was set differently than the expected value.
Changing all the test data files to use qemu-xen ensures
predictable results wrt default video RAM size.

libvirt may automatically add a pci-root or pcie-root controller to a
domain, depending on the arch/machinetype, and it hopefully always
makes the right decision about which to add (since in all cases these
controllers are an implicit part of the virtual machine).
But it's always possible that someone will create a config that
explicitly supplies the wrong type of PCI controller for the selected
machinetype. In the past that would lead to an error later when
libvirt was trying to assign addresses to other devices, for example:
XML error: PCI bus is not compatible with the device at
0000:00:02.0. Device requires a PCI Express slot, which is not
provided by bus 0000:00
(that's the error message that appears if you replace the pcie-root
controller in a Q35 domain with a pci-root controller).
This patch adds a check at the same place that the implicit
controllers are added (to ensure that the same logic is used to check
which type of pci root is correct). If a pci controller with index='0'
is already present, we verify that it is of the model that we would
have otherwise added automatically; if not, an error is logged:
The PCI controller with index='0' must be " model='pcie-root' for
this machine type, " but model='pci-root' was found instead.

Now that we have all the pieces in place, we can add the 'iothread=#' to

Add the ability to add an 'iothread' to the controller which will be how
virtio-scsi-pci and virtio-scsi-ccw iothreads have been implemented in qemu.
Describe the new functionality and add tests to parse/validate that the
new attribute can be added.
An iothread for virtio-scsi is a property of the controller. Add a lookup
of the 'virtio-scsi-pci' and 'virtio-scsi-ccw' device properties and parse

while support for virtio-scsi in general was added in qemu 1.4.
Modify the various mock capabilities replies (by hand) to reflect the
when virtio-scsi was supported and then specifically when the iothread
property was added. For versions prior to 1.4, use the no device error
return for virtio-scsi. For versions 1.4 to before 2.4, add some data

because sasl library requires the IP address and service to be delimited by a
semicolon. The string form is a completely internal matter, however once the
admin interfaces to retrieve client identity information are merged, we should
return the socket address string in a common format, e.g. format defined by
URI rfc-3986, i.e. the IP address and service are delimited by a colon and
in case of an IPv6 address, square brackets are added:
Examples:

Admin API needs a way of addressing specific clients. Unlike servers, which we
are happy to address by names both because its name reflects its purpose (to
some extent) and we only have two of them (so far), naming clients doesn't make

disconnect followed by a reconnect, b) we can't predict what kind of requests
it's going to send to daemon, and c) the are loads of them comming and going,

The man page says: "(Re)-Connect to the hypervisor. When the shell is
first started, this is automatically run with the URI parameter
requested by the "-c" option on the command line." However, if you run:
virsh -c 'test://default' 'connect; uri'
the output will not be 'test://default'. That's because the 'connect'
command does not care about any virsh-only related settings and if it is
run without parameters, it connects with @uri == NULL. Not only that
doesn't comply to what the man page describes, but it also doesn't make

Similarly to what commit 7140807917 did with some internal paths,
clear vnc socket paths that were generated by us. Having such path in
the definition can cause trouble when restoring the domain. The path is
generated to the per-domain directory that contains the domain ID.
However, that ID will be different upon restoration, so qemu won't be
able to create that socket because the directory will not be prepared.
To be able to migrate to older libvirt, skip formatting the socket path
in migratable XML if it was autogenerated. And mark it as autogenerated
if it already exists and we're parsing live XML.

While working on the tests for the secret initialization vector, I found
that the existing iSCSI tests were lacking in how they defined the IQN.
Many had IQN's of just 'iqn.1992-01.com.example' for one disk while using
'iqn.1992-01.com.example/1' for the second disk (same for hostdevs - guess
how they were copied/generated).
Typically (and documented this way), IQN's would include be of the form
'iqn.1992-01.com.example:storage/1' indicating an IQN using "storage" for
naming authority specific string and "/1" for the iSCSI LUN.
So modify the input XML's to use the more proper format - this of course
has a ripple effect on the output XML and the args.

virTypedParamsValidate currently uses an index based check to find
duplicate parameters. This check does not work. Consider the following
simple example:
We have only 2 keys
A (multiples allowed)
B (multiples NOT allowed)
We are given the following list of parameters to check:
A
A
B
If you work through the validation loop you will see that our last iteration
through the loop has i=2 and j=1. In this case, i > j and keys[j].value.i will
indicate that multiples are not allowed. Both conditionals are satisfied so
an incorrect error will be given: "parameter '%s' occurs multiple times"
This patch replaces the index based check with code that remembers
the name of the last parameter seen and only triggers the error case if
the current parameter name equals the last one. This works because the
list is sorted and duplicate parameters will be grouped together.
In reality, we hit this bug while using selective block migration to migrate

This is backed by the qemu device pxb-pcie, which will be available in
qemu 2.6.0.
As with pci-expander-bus (which uses qemu's pxb device), the busNr
attribute and <node> subelement of <target> are used to set the bus_nr
and numa_node options.
During post-parse we validate that the domain's machinetype is
q35-based (since the device shows up for 440fx-based machinetypes, but
is unusable), as well as checking that <node> specifies a node that is
actually configured on the guest.
This controller provides a single PCIe port on a new root. It is
similar to pci-expander-bus, intended to provide a bus that can be
associated with a guest-identifiable NUMA node, but is for
machinetypes with PCIe rather than PCI (e.g. q35-based machinetypes).
Aside from PCIe vs. PCI, the other main difference is that a
pci-expander-bus has a companion pci-bridge that is automatically
attached along with it, but pcie-expander-bus has only a single port,
and that port will only connect to a pcie-root-port, or to a
pcie-switch-upstream-port. In order for the bus to be of any use in
the guest, it must have either a pcie-root-port or a
pcie-switch-upstream-port attached (and one or more
pcie-switch-downstream-ports attached to the
pcie-switch-upstream-port).
The pxb device is a PCIe expander bus that can be added to any
Q35-based machinetype. A single PCIe port (*not* hotpluggable) is
provided; if more than one device is desired, or if hotplug
support is needed, either a pcie-root-port, or some combination of
pcie-switch-upstream-port and pcie-swith-downstream-ports must be
added to it. It can have a NUMA node number associated with it, as
well as a bus number.
This is backed by the qemu device "pxb".
The pxb device always includes a pci-bridge that is at the bus number
of the pxb + 1.
busNr and <node> from the <target> subelement are used to set the
bus_nr and numa_node options for pxb.
During post-parse we validate that the domain's machinetype is
440fx-based (since the pxb device only works on 440fx-based machines),
and <node> also gets a sanity check to assure that the NUMA node
specified for the pxb (if any - it's optional) actually exists on the
guest.
This is a standard PCI root bus (not a bridge) that can be added to a
440fx-based domain. Although it uses a PCI slot, this is *not* how it
is connected into the PCI bus hierarchy, but is only used for
control. Each pci-expander-bus provides 32 slots (0-31) that can
accept hotplug of standard PCI devices.
The usefulness of pci-expander-bus relative to a pci-bridge is that
the NUMA node of the bus can be specified with the <node> subelement
of <target>. This gives guest-side visibility to the NUMA node of
attached devices (presuming that management apps only assign a device
to a bus that has a NUMA node number matching the node number of the
device on the host).
Each pci-expander-bus also has a "busNr" attribute. The expander-bus
itself will take the busNr specified, and all buses that are connected
to this bus (including the pci-bridge that is automatically added to
any expander bus of model "pxb" (see the next commit)) will use
busNr+1, busNr+2, etc, and the pci-root (or the expander-bus with next
lower busNr) will use bus numbers lower than busNr.
The pxb device is a PCI expander bus that can be added to any
440fx-based machinetype. The PCI bus that is created has 32 standard
PCI slots (hotpluggable). It can have a NUMA node number associated
with it, as well as a bus number.
When support for dmi-to-pci-bridge was added, it was assumed that,
just as with the pci-root bus, slot 0 was reserved. This is not the
case - it can be used to connect a device just like any other slot, so
remove the restriction and update the test cases that auto-assign an
address on a dmi-to-pci-bridge.
* Add a test for listen=XXX and <listen address=YYY/> collision error
* Add an explicit test for listen=XXX duplicated to <listen address=XXX/>
We implicitly test it elsewhere but I figure it's better to be explicit,

back compat if/when we support <listen type='socket'/> syntax

Commit d77ffb6876 added not only reporting of the PCI header type, but
also parsing of that information. However, because there was no parsing
done for the other sub-PCI capabilities, if there was any other
capability then a valid header type name (like phys_function or
virt_functions) the parsing would fail. This prevented passing node
device XMLs that we generated into our own functions when dealing with,
e.g. with SRIOV cards.
Instead of reworking the whole parsing, just fix this one occurence and
remove a test for it for the time being. Future patches will deal with
the rest.

In some cases it's impractical to use the regular APIs as the bitmap
size needs to be pre-declared. These new APIs allow to use bitmaps that
self expand.
The new code adds a property to the bitmap to track the allocation of
memory so that VIR_RESIZE_N can be used.
It was too similar to the non-scaled alternative.

This patch adds support for "vpindex", "runtime", "synic",
"stimer", and "vendor_id" features available in qemu 2.5+.
- When Hyper-V "vpindex" is on, guest can use MSR HV_X64_MSR_VP_INDEX
to get virtual processor ID.
- Hyper-V "runtime" enlightement feature allows to use MSR
HV_X64_MSR_VP_RUNTIME to get the time the virtual processor consumes
running guest code, as well as the time the hypervisor spends running
code on behalf of that guest.
- Hyper-V "synic" stands for Synthetic Interrupt Controller, which is
lapic extension controlled via MSRs.
- Hyper-V "stimer" switches on Hyper-V SynIC timers MSR's support.
Guest can setup and use fired by host events (SynIC interrupt and
appropriate timer expiration message) as guest clock events
- Hyper-V "reset" allows guest to reset VM.
- Hyper-V "vendor_id" exposes hypervisor vendor id to guest.

The test can return positive value even though it should have failed. It just
returns the value parser returned, which should be flipped back to -1 if
something went wrong or the result was unexpected, but it isn't.
After 9c17d665fd the tap device for ethernet network type is
automatically precreated before spawning qemu. Problem is, the
qemuxml2argvtest wasn't updated and thus is failing. Because of
all the APIs that new code is calling, I had to mock a lot. Also,
since the tap FDs are labeled separately from the rest of the
devices/files I had to enable NOP security driver for the test
too.

When constructing SCSI hostdev command line for qemu, the
/sys/bus/scsi/devices/... dir is scanned. Unfortunately, even in
the tests. This is needed to determine the name of SCSI device to
passthrough to qemu, because in the domain XML we were given its
address instead. Anyway, we should not be touching live system
data in our test suite as it produced unpredictable results. The
test is regressing from 1e9a083742 on.

Problem is that in the test any status file matching
tests/nssdata/*.status is loaded as it contains IP addresses that
are parsed. However, there's no order specified in which the
files are loaded. Therefore on different systems the order may be
different. This is then producing an unexpected results.
Instead of defining an order in which the files are loaded, make
the code that checks for missing IP addresses (or redundant ones)
cope with unordered list of addresses. The reasoning behind is
that the code doing the parsing is used in real NSS module where
we don't care for ordering.

This allows setting the address in host and/or network order and makes
the naming consistent. Now you don't need to call [hn]to[nh]l()
functions as that is taken care of by these functions. Also, now
the *NetOrder take the address in network order, the other functions in
host order so the naming and usage is consistent. Some places were
having the address in network order and calling ntohl() just so the
original function can call htonl() again. This makes it nicer to read.

If a <graphics type='spice'> has no port nor tlsPort set, the generated
QEMU command line will contain -spice port=0.
This is later going to be ignored by spice-server, but it's better not
to add it at all in this situation.
As an empty -spice is not allowed, we still need to append port=0 if we
did not add any other argument.
Even if nss is disabled, the build system tries to build some
targets like libnss_libvirt_impl.la and nsstest. Hide those
under the "if WITH_NSS" block like the rest of NSS plugin bits.
If we expose this information, which is one byte in every PCI config
file, we let all mgmt apps know whether the device itself is an endpoint
or not so it's easier for them to decide whether such device can be
passed through into a VM (endpoint) or not (*-bridge).

The only purpose of this test is to catch possible linking
problems with libnss_libvirt.so.2.
One of the problems I faced was that the NSS plugin was unloaded
immediately after it got loaded and the name resolution process
continued with next configured option. Without any error. It was
very hard to debug why until I created this simple test and found
out immediately that there were some symbols missing. The reason
why problem was not caught in nsstest is that in the test we want
to use all the fancy stuff and therefore link it with libvirt.la.
So even if there's a symbol missing in the NSS plugin it will be
found in the libvirt.la.
But even after I resolved the issue we still need this test
because files the NSS plugin is built from are still live (mostly
those under utils/ dir). So as they change new symbol might be
required which would render the NSS plugin unusable.

None of the existing domXML configs under tests/* specify a
default cache mode since default generally means "use the
hypervisor default" and is left unset by the various hypervisor
drivers. Add a config to tests/domainschemadata that specifies
cache='default'.
Currently we spawn couple of binaries in our test suite.
Moreover, we provide some spoofed versions of system binaries
hoping that those will be executed instead of the system ones.
For instance, for testing SSH socket we have written our own ssh
binary for producing predictable results. We certainly don't want
to execute the system ssh binary.
However, in order to prefer our binaries over system ones, we
need to set PATH environment variable. But this is done only at
the Makefile level. So if anybody runs a test by hand that
expects our spoofed binary, the test ends up executing real
system binaries. This is not good. In fact, it's terribly wrong.
The fix lies in a small trick - putting our build directory at
the beginning of the PATH environment variable in each test.
Hopefully, since every test has this VIRT_TEST_MAIN* wrapper, we
can fix this at a single place.
Moreover, while this removes setting PATH for our tests written
in bash, it's safe as we are not calling anything ours that would
require PATH change there.

We include the file in plenty of places. This is mostly due to
historical reasons. The only place that needs something from the
header file is storage_backend_fs which opens _PATH_MOUNTED. But
it gets the file included indirectly via mntent.h. At no other
place in our code we need _PATH_.*. Drop the include and
configure check then.

Patch adds a generic DO_TEST_FULL macro, some PASS/FAIL macros to better
visually distinguish tests that should fail and tests that should pass. Also,
some cosmetic changes like renames and direct call to fprintf is replaced with
our VIR_TEST_DEBUG macro, as using testutils should be our preferred way of
reporting errors in tests.
Since servers know their name, there is no need to supply such
information twice. Also defeats inconsistencies.
