99ea70b49a spec: Avoid RPM verification errors on nwfilter XMLs
/etc/libvirt/nwfilter/*.xml files are installed with no UUID, which
means libvirtd will automatically alter all of them once it starts. Thus
RPM verification will always fail on them. Let's use a trick similar to
the default network XML and store nwfilter XMLs in /usr/share. They will
be copied into /etc in %post. Additionally the /etc files are marked as
%ghost so that they are uninstalled if the RPM package is removed.

Note that the %post script overwrites existing files with new ones on
upgrade, which is what has always been happening.

b6be55d7c5 qemu: Fix crash during qemuStateCleanup
Rather than waiting until we've free'd up all the resources, cause the
'workerPool' thread pool to flush as soon as possible during stateCleanup.
Otherwise, it's possible something waiting to run will SEGV such as is the
case during race conditions of simultaneous exiting libvirtd and qemu process.
Resolves the following crash:

2e66047cc0 daemon: Fix crash during daemon cleanup
Do not dereference the 'dmn' until after the virStateCleanup is completed.

During initialization, virStateInitialize requires/uses the "dmn" as the
argument to/for the daemonInhibitCallback functions. Thus, cleanup cannot
dereference 'dmn' until after calling the virStateCleanup which calls the
the daemonInhibitCallback using 'dmn'; otherwise, the following crash occurs:

e24ff1f38e qemu: Don't assume secret provided for LUKS encryption
https://bugzilla.redhat.com/show_bug.cgi?id=1405269

If a secret was not provided for what was determined to be a LUKS
encrypted disk (during virStorageFileGetMetadata processing when
called from qemuDomainDetermineDiskChain as a result of hotplug
attach qemuDomainAttachDeviceDiskLive), then do not attempt to
look it up (avoiding a libvirtd crash) and do not alter the format
to "luks" when adding the disk; otherwise, the device_add would
fail with a message such as:

   "unable to execute QEMU command 'device_add': Property 'scsi-hd.drive'
    can't find value 'drive-scsi0-0-0-0'"

because of assumptions that when the format=luks that libvirt would have
provided the secret to decrypt the volume.

Access to unlock the volume will thus be left to the application.

7627dcdc7d virtlogd: Don't stop or restart along with libvirtd
Commit 839a060 tied the lifecycle of virtlogd more
closely to that of libvirtd. Unfortunately, while starting
virtlogd when libvirtd is started is definitely a good idea,
restarting virtlogd or shutting it down at any time outside
of system poweroff is not.

Revert part of that commit by removing the PartOf= lines,
meaning that only startup requests will be propagated from
libvirtd to virtlogd.

We already guarantee that virtlogd.socket is enabled/disabled

been installed and is started before rebooting, then
virtlogd.socket will not be running and guest startup will
fail.

Add Requires=virtlogd.socket to libvirtd.service to make sure
virtlogd.socket is always started along with libvirtd.service,
and add Before=libvirtd.service to both virtlogd.socket and
virtlogd.service so that virtlogd never disappears before
libvirtd has exited.

Also add PartOf=libvirtd.service to both virtlogd.socket and
virtlogd.service, so that virtlogd can be shut down when not
needed.

2f469c062c qemu: capabilities: Don't partially reprope caps on process reconnect
Thanks to the complex capability caching code virQEMUCapsProbeQMP was
never called when we were starting a new qemu VM. On the other hand,
when we are reconnecting to the qemu process we reload the capability
list from the status XML file. This means that the flag preventing the
function being called was not set and thus we partially reprobed some of
the capabilities.

The recent addition of CPU hotplug clears the
QEMU_CAPS_QUERY_HOTPLUGGABLE_CPUS if the machine does not support it.
The partial re-probe on reconnect results into attempting to call the
unsupported command and then killing the VM.

Remove the partial reprobe and depend on the stored capabilities. If it
will be necessary to reprobe the capabilities in the future, we should
do a full reprobe rather than this partial one.

06f5c46e5d network: fix endless loop when starting network with multiple IPs and no dhcp
commit 9065cfaa added the ability to disable DNS services for a
libvirt virtual network. If neither DNS nor DHCP is needed for a
network, then we don't need to start dnsmasq, so code was added to
check for this.

Unfortunately, it was written with a great lack of attention to detail
(I can say that, because I was the author), and the loop that checked
if DHCP is needed for the network would never end if the network had
multiple IP addresses and the first <ip> had no <dhcp> subelement
(which would have contained a <range> or <host> subelement, thus
requiring DHCP services).

This patch rewrites the check to be more compact and (more
importantly) finite.

This bug was present in release 2.2.0 and 2.3.0, so will need to be
backported to any relevant maintainence branches.

52cc796d1c qemu: allow 32 slots on pcie-expander-bus, not just 1
When I added support for the pcie-expander-bus controller in commit
bc07251f, I incorrectly thought that it only had a single slot
available. Actually it has 32 slots, just like the root complex aka
pcie-root (the part that I *did* get correct is that unlike pcie-root
a pcie-expander-bus doesn't allow any integrated endpoint devices -
only pcie-root-ports and dmi-to-pci-controllers are allowed).

4c052baf46 qemu: Only use memory-backend-file with NUMA if needed
If this reminds you of a commit message from around a year ago, it's
41c2aa729f and yes, we're dealing with
"the same thing" again.  Or f309db1f4d and
it's similar.

There is a logic in place that if there is no real need for
memory-backend-file, qemuBuildMemoryBackendStr() returns 0.  However
that wasn't the case with hugepage backing.  The reason for that was
that we abused the 'pagesize' variable for storing that information, but
we should rather have a separate one that specifies whether we really
need the new object for hugepage backing.  And that variable should be
set only if this particular NUMA cell needs special treatment WRT
hugepages.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.

[![CII Best Practices](https://bestpractices.coreinfrastructure.org/projects/355/badge)](https://bestpractices.coreinfrastructure.org/projects/355)
Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
Further information about the libvirt project can be found on the
website:
[https://libvirt.org](https://libvirt.org)
License
-------
The libvirt C API is distributed under the terms of GNU Lesser General
Public License, version 2.1 (or later). Some parts of the code that are
not part of the C library may have the more restrictive GNU General
Public License, version 2.1 (or later). See the files `COPYING.LESSER`
and `COPYING` for full license terms & conditions.
Installation
------------
Libvirt uses the GNU Autotools build system, so in general can be built
and installed with the usual commands. For example, to build in a manner
that is suitable for installing as root, use:
```
$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install
```
While to build & install as an unprivileged user
```
$ ./configure --prefix=$HOME/usr
$ make
$ make install
```
The libvirt code relies on a large number of 3rd party libraries. These will
be detected during execution of the `configure` script and a summary printed
which lists any missing (optional) dependencies.
Contributing
------------
The libvirt project welcomes contributions in many ways. For most components
the best way to contribute is to send patches to the primary development
mailing list. Further guidance on this can be found on the website:
[https://libvirt.org/contribute.html](https://libvirt.org/contribute.html)
Contact
-------
The libvirt project has two primary mailing lists:
* libvirt-users@redhat.com (**for user discussions**)
* libvir-list@redhat.com (**for development only**)
Further details on contacting the project are available on the website:
[https://libvirt.org/contact.html](https://libvirt.org/contact.html)

Threading in the libvirtd daemon
================================
To allow efficient processing of RPC requests, the libvirtd daemon
makes use of threads.
- The process leader. This is the initial thread of control
when the daemon starts running. It is responsible for
initializing all the state, and starting the event loop.
Once that's all done, this thread does nothing except
wait for the event loop to quit, thus indicating an orderly
shutdown is required.
- The event loop. This thread runs the event loop, sitting
in poll() on all monitored file handles, and calculating
and dispatching any timers that may be registered. When
this thread quits, the entire daemon will shutdown.
- The workers. These 'n' threads all sit around waiting to
process incoming RPC requests. Since RPC requests may take
a long time to complete, with long idle periods, there will
be quite a few workers running.
The use of threads obviously requires locking to ensure safety when
accessing/changing data structures.
- the top level lock is on 'struct qemud_server'. This must be
held before acquiring any other lock
- Each 'struct qemud_client' object has a lock. The server lock
must be held before acquiring it. Once the client lock is acquired
the server lock can (optionally) be dropped.
- The event loop has its own self-contained lock. You can ignore
this as a caller of virEvent APIs.
The server lock is used in conjunction with a condition variable
to pass jobs from the event loop thread to the workers. The main
event loop thread handles I/O from the client socket, and once a
complete RPC message has been read off the wire (and optionally
decrypted), it will be placed on the 'dx' job queue for the
associated client object. The job condition will be signalled and
a worker will wakup and process it.
The worker thread must quickly drop its locks on the server and
client to allow the main event loop thread to continue running
with its other work. Critically important, is that now libvirt
API call will ever be made with the server or client locks held.

<p class="example">See <a href="api_extension/0009-support-all-flags-in-test-driver.patch">0009-support-all-flags-in-test-driver.patch</a></p>
<p> <p>
Any cleanups resulting from the changes should be added as separate The qemu changes were easier to split into two phases, one for
patches at the end of the series. updating the mapping between the new XML and the hypervisor
command line arguments, and one for supporting all possible
flags of the new API:
</p>
<p class="example">See <a href="api_extension/0010-improve-vcpu-support-in-qemu-command-line.patch">0010-improve-vcpu-support-in-qemu-command-line.patch</a>
and <a href="api_extension/0011-complete-vcpu-support-in-qemu-driver.patch">0011-complete-vcpu-support-in-qemu-driver.patch</a></p>
<p>
Finally, the example breaks the xen driver changes across four
patches. One maps the XML changes to the hypervisor command,
the next two are independently implementing the getter and
setter APIs, and the last one provides cleanup of code that was
rendered dead by the new API.
</p>
<p class="example">See <a href="api_extension/0012-improve-vcpu-support-in-xen-command-line.patch">0012-improve-vcpu-support-in-xen-command-line.patch</a>,
<a href="api_extension/0013-improve-getting-xen-vcpu-counts.patch">0013-improve-getting-xen-vcpu-counts.patch</a>,
<a href="api_extension/0014-improve-setting-xen-vcpu-counts.patch">0014-improve-setting-xen-vcpu-counts.patch</a>,
and <a href="api_extension/0015-remove-dead-xen-code.patch">0015-remove-dead-xen-code.patch</a></p>
<p>
The exact details of the example code are probably uninteresting
unless you're concerned with virtual cpu management.

Subject: [PATCH 01/15] vcpu: add current attribute to <vcpu> element
Syntax agreed on in
https://www.redhat.com/archives/libvir-list/2010-September/msg00476.html
<domain ...>
<vcpu current='x'>y</vcpu>
...
can now be used to specify 1 <= x <= y current vcpus, in relation
to the boot-time max of y vcpus. If current is omitted, then
current and max are assumed to be the same value.
* docs/schemas/domain.rng: Add new attribute.
* docs/formatdomain.html.in: Document it.
* tests/qemuxml2argvdata/qemuxml2argv-smp.xml: Add to
domainschematest.
* tests/xml2sexprdata/xml2sexpr-pv-vcpus.xml: Likewise.

Subject: [PATCH 05/15] vcpu: implement the remote protocol
Done by editing the first three files, then running
'make -C src rpcgen', then editing src/remote_protocol-structs
to match.
* daemon/remote.c (remoteDispatchDomainSetVcpusFlags)
(remoteDispatchDomainGetVcpusFlags): New functions.
* src/remote/remote_driver.c (remoteDomainSetVcpusFlags)
(remoteDomainGetVcpusFlags, remote_driver): Client side
serialization.
* src/remote/remote_protocol.x
(remote_domain_set_vcpus_flags_args)
(remote_domain_get_vcpus_flags_args)
(remote_domain_get_vcpus_flags_ret)
(REMOTE_PROC_DOMAIN_SET_VCPUS_FLAGS)
(REMOTE_PROC_DOMAIN_GET_VCPUS_FLAGS): Define wire format.
* daemon/remote_dispatch_args.h: Regenerate.
* daemon/remote_dispatch_prototypes.h: Likewise.
* daemon/remote_dispatch_table.h: Likewise.
* src/remote/remote_protocol.c: Likewise.
* src/remote/remote_protocol.h: Likewise.
* src/remote_protocol-structs: Likewise.

From 50c51f13e2af04afac46e181c4ed62581545a488 Mon Sep 17 00:00:00 2001

Subject: [PATCH 06/15] vcpu: make old API trivially wrap to new API
Note - this wrapping is completely mechanical; the old API will
function identically, since the new API validates that the exact
same flags are provided by the old API. On a per-driver basis,
it may make sense to have the old API pass a different set of flags,
but that should be done in the per-driver patch that implements
the full range of flag support in the new API.
* src/esx/esx_driver.c (esxDomainSetVcpus, escDomainGetMaxVpcus):
Move guts...
(esxDomainSetVcpusFlags, esxDomainGetVcpusFlags): ...to new
functions.
(esxDriver): Trivially support the new API.
* src/openvz/openvz_driver.c (openvzDomainSetVcpus)
(openvzDomainSetVcpusFlags, openvzDomainGetMaxVcpus)
(openvzDomainGetVcpusFlags, openvzDriver): Likewise.

* src/test/test_driver.c (testSetVcpus, testDomainSetVcpusFlags)

Likewise.
* src/vbox/vbox_tmpl.c (vboxDomainSetVcpus)
(vboxDomainSetVcpusFlags, virDomainGetMaxVcpus)

From bf945ee97b72d3b0c4fc2da04530f5294f529d66 Mon Sep 17 00:00:00 2001
From: Eric Blake <eblake@redhat.com>
Date: Wed, 29 Sep 2010 15:20:23 -0600
Subject: [PATCH 08/15] vcpu: add virsh support
* tools/virsh.c (cmdSetvcpus): Add new flags. Let invalid
commands through to driver, to ease testing of hypervisor argument
validation.
(cmdMaxvcpus, cmdVcpucount): New commands.
(commands): Add new commands.
* tools/virsh.pod (setvcpus, vcpucount, maxvcpus): Document new
behavior.

From 4617eedfaeee2b187a1f14691d25746ba3ff31b6 Mon Sep 17 00:00:00 2001

Subject: [PATCH 07/15] vcpu: support maxvcpu in domain_conf
Although this patch adds a distinction between maximum vcpus and
current vcpus in the XML, the values should be identical for all
drivers at this point. Only in subsequent per-driver patches will
a distinction be made.
In general, virDomainGetInfo should prefer the current vcpus.
* src/conf/domain_conf.h (_virDomainDef): Adjust vcpus to unsigned
short, to match virDomainGetInfo limit. Add maxvcpus member.
* src/conf/domain_conf.c (virDomainDefParseXML)
(virDomainDefFormat): parse and print out vcpu details.
* src/xen/xend_internal.c (xenDaemonParseSxpr)
(xenDaemonFormatSxpr): Manage both vcpu numbers, and require them
to be equal for now.
* src/xen/xm_internal.c (xenXMDomainConfigParse)
(xenXMDomainConfigFormat): Likewise.
* src/phyp/phyp_driver.c (phypDomainDumpXML): Likewise.
* src/openvz/openvz_conf.c (openvzLoadDomains): Likewise.
* src/openvz/openvz_driver.c (openvzDomainDefineXML)
(openvzDomainCreateXML, openvzDomainSetVcpusInternal): Likewise.
* src/vbox/vbox_tmpl.c (vboxDomainDumpXML, vboxDomainDefineXML):
Likewise.
* src/xenapi/xenapi_driver.c (xenapiDomainDumpXML): Likewise.
* src/xenapi/xenapi_utils.c (createVMRecordFromXml): Likewise.
* src/esx/esx_vmx.c (esxVMX_ParseConfig, esxVMX_FormatConfig):
Likewise.
* src/qemu/qemu_conf.c (qemuBuildSmpArgStr)
(qemuParseCommandLineSmp, qemuParseCommandLine): Likewise.
* src/qemu/qemu_driver.c (qemudDomainHotplugVcpus): Likewise.

Subject: [PATCH 12/15] vcpu: improve vcpu support in xen command line
This patch series focuses on xendConfigVersion 2 (xm_internal) and 3
(xend_internal), but leaves out changes for xenapi drivers.
See this link for more details about vcpu_avail for xm usage.
http://lists.xensource.com/archives/html/xen-devel/2009-11/msg01061.html
This relies on the fact that def->maxvcpus can be at most 32 with xen.
* src/xen/xend_internal.c (xenDaemonParseSxpr)
(sexpr_to_xend_domain_info, xenDaemonFormatSxpr): Use vcpu_avail
when current vcpus is less than maximum.
* src/xen/xm_internal.c (xenXMDomainConfigParse)
(xenXMDomainConfigFormat): Likewise.
* tests/xml2sexprdata/xml2sexpr-pv-vcpus.sexpr: New file.
* tests/sexpr2xmldata/sexpr2xml-pv-vcpus.sexpr: Likewise.
* tests/sexpr2xmldata/sexpr2xml-pv-vcpus.xml: Likewise.
* tests/xmconfigdata/test-paravirt-vcpu.cfg: Likewise.
* tests/xmconfigdata/test-paravirt-vcpu.xml: Likewise.
* tests/xml2sexprtest.c (mymain): New test.
* tests/sexpr2xmltest.c (mymain): Likewise.
* tests/xmconfigtest.c (mymain): Likewise.

From e443a003129a172a7332f3cb6e40b3c39363ed5e Mon Sep 17 00:00:00 2001
From: Eric Blake <eblake@redhat.com>
Date: Thu, 14 Oct 2010 16:17:18 -0600
Subject: [PATCH 14/15] vcpu: improve support for setting xen vcpu counts
Tested with RHEL 5.6 (xendConfigVersion 2, where xend_internal
controls live domains and xm_internal controls inactive domains).
Hopefully this works with xendConfigVersion 3 (where xend_internal
controls everything).
* src/xen/xen_driver.c (xenUnifiedDomainSetVcpusFlags): Support
more flags.
(xenUnifiedGetMaxVcpus): Export.
* src/xen/xm_internal.h (xenXMDomainSetVcpusFlags): New prototype.
* src/xen/xend_internal.h (xenDaemonDomainSetVcpusFlags): Likewise.
* src/xen/xen_driver.h (xenUnifiedGetMaxVcpus): Likewise.
* src/xen/xm_internal.c (xenXMDomainSetVcpusFlags): New function.
* src/xen/xend_internal.c (xenDaemonDomainSetVcpusFlags): Likewise.

<h1>Storage management architecture</h1>
<p>
The storage management APIs are based around 2 core concepts
</p>
<ol>
<li>
<strong>Volume</strong> - a single storage volume which can
be assigned to a guest, or used for creating further pools. A
volume is either a block device, a raw file, or a special format
file.
</li>
<li>
<strong>Pool</strong> - provides a means for taking a chunk
of storage and carving it up into volumes. A pool can be used to
manage things such as a physical disk, a NFS server, a iSCSI target,
a host adapter, an LVM group.
</li>
</ol>
<p>
These two concepts are mapped through to two libvirt objects, a
<code>virStorageVolPtr</code> and a <code>virStoragePoolPtr</code>,
each with a collection of APIs for their management.

it is vulnerable to MITM attacks and the MD5 hash can be brute-forced

<h3><a id="ACL_server_username">Username/password auth</a></h3>
<p>
As noted above, the DIGEST-MD5 mechanism is considered obsolete and should
not be used anymore. To provide a simple username/password auth scheme on
the libvirt UNIX socket or TLS listeners, however, it is possible to use
the SCRAM mechanism. The <code>auth_unix_ro</code>, <code>auth_unix_rw</code>,
<code>auth_tls</code> config params in <code>libvirt.conf</code> can be used
to turn on SASL auth in these listeners.
</p>
<p>
Since the libvirt SASL config file defaults to using GSSAPI (Kerberos), a
config change is rquired to enable plain password auth. This is done by
editting <code>/etc/sasl2/libvirt.conf</code> to set the <code>mech_list</code>
parameter to <code>scram-sha-1</code>.
