My earlier commit be46f61326 was incomplete. It removed caching of
microcode version in the CPU driver, which means the capabilities XML
will see the correct microcode version. But it is also cached in the
QEMU capabilities cache where it is used to detect whether we need to
reprobe QEMU. By missing the second place, the original commit
be46f61326 made the situation even worse since libvirt would report
correct microcode version while still using the old host CPU model

The microcode version checks are used to invalidate cached CPU data we
get from QEMU. To minimize /proc/cpuinfo parsing the microcode version
was only read when libvirtd started and cached for the daemon's
lifetime. However, the CPU microcode can change anytime (updating the
microcode package can automatically upload it to the CPU) and we need to
stop caching it to avoid using stale CPU model data.

Commit 6534b3c4 tried to raise an error when there is no numa
nodes by setting access='shared' in the domain config, but added
a helper called from qemuDomainDeviceDefValidate instead of a
helper called from qemuDomainDefValidate for XML:
<memoryBacking>
<hugepages/>
<access mode='shared'/>
</memoryBacking>
Since there are no memory devices in the test XML, there would
be no validation failure, but the test added was still failing.
Investigating that it turns out that unnecessary XML elements
were causing the failure (no need for <video>, <graphics>,
<pm>, usb controller model "piix3-uhci", disk attribute for
"discard='unmap'", <serial>, <console>, <channel> and a
memballoon model). Removing all those before moving the method
caused the test to succeed.
So this patch moves the validation to the right place and
removes all the unnecessary XML pieces that were causing
a false validation failure.

If @vm has flagged as "to be removed" virDomainObjListFindByNameLocked
returns NULL (although the definition actually exists). Therefore, the
possibility exits that "virHashAddEntry" will raise the error
"Duplicate key" => virDomainObjListAddObjLocked fails =>
virDomainObjEndAPI(&vm) is called and this leads to a freeing of @def
since @def is already assigned to vm->def. But actually this leads to
a double free since the common usage pattern is that the caller of
virDomainObjListAdd(Locked) is responsible for freeing @def in case of
an error.
Let's fix this by setting vm->def to NULL in case of an error.

QEMU is probed through monitor fd to check capabilities during libvirtd init.
The monitor fd is closed after probing by virQEMUCapsInitQMPCommandFree
that calls virQEMUCapsInitQMPCommandAbort that calls qemuMonitorClose,
the latter one notifies the event loop via an interrupt handle in
qemuMonitorUnregister and after then closes monitor fd.
There could be a case when interrupt is sent after eventLoop is unlocked
but before virEventPollRunOnce blocks in poll, shortly before file
descriptor is closed by qemuMonitorClose. Then poll receives closed monitor
fd in fdset and returns EBADF.
EBADF is not mentioned as a valid errno on macOS poll man-page but such
behaviour can appear release-to-release, according to cpython:

It was found that in cases with host devices virProcessKillPainfully

That is due to cleanup and reset of devices which might include a
secondary bus reset that on top of the actions taken has a 1s delay
to let the bus settle. Due to that guests with plenty of Host devices
could easily exceed the default timeouts.

So the procedure to detect SEV support works like this:
1) we detect that sev-guest is among the QOM types and set the cap flag
2) we probe the monitor for SEV support
- this is tricky, because QEMU with compiled SEV support will always
report -object sev-guest and query-sev-capabilities command, that
however doesn't mean SEV is supported
3) depending on what the monitor returned, we either keep or clear the
capability flag for SEV
Commit a349c6c21c added an explicit check for "GenericError" in the
monitor reply to prevent libvirtd to spam logs about missing
'query-sev-capabilities' command. At the same time though, it returned
success in this case which means that we didn't clear the capability
flag afterwards and happily formatted SEV into qemuCaps. Therefore,
adjust all the relevant callers to handle -1 on errors, 0 on SEV being
unsupported and 1 on SEV being supported.

Several cases were found needing /tmp, for example ceph will try to list /tmp
This is a compromise of security and usability:
- we only allow generally enumerating the base dir
- enumerating anything deeper in the dir is at least guarded by the
"owner" restriction, but while that protects files of other services
it won't protect qemu instances against each other as they usually run
with the same user.
- even with the owner restriction we only allow read for the wildcard

If a guest runs unconfined <seclabel type='none'>, but libvirtd is
confined then the peer for signal can only be detected as
'unconfined'. That triggers issues like:
apparmor="DENIED" operation="signal"
profile="/usr/sbin/libvirtd" pid=22395 comm="libvirtd"
requested_mask="send" denied_mask="send" signal=term peer="unconfined"
To fix this add unconfined as an allowed peer for those operations.
I discussed with the apparmor folks, right now there is no better
separation to be made in this case. But there might be further down the
road with "policy namespaces with scope and view control + stacking"
This is more a use-case addition than a fix to the following two changes:
- 3b1d19e6 AppArmor: add rules needed with additional mediation features

Previously we were ignoring "nodeset" attribute for hugepage pages
if there was no guest NUMA topology configured in the domain XML.
Commit <fa6bdf6afa878b8d7c5ed71664ee72be8967cdc5> partially fixed
that issue but it introduced a somehow valid regression.
In case that there is no guest NUMA topology configured and the
"nodeset" attribute is set to "0" it was accepted and was working
properly even though it was not completely valid XML.
This patch introduces a workaround that it will ignore the nodeset="0"
only in case that there is no guest NUMA topology in order not to
hit the validation error.
After this commit the following XML configuration is valid:
<memoryBacking>
<hugepages>
<page size='2048' unit='KiB' nodeset='0'/>
</hugepages>
</memoryBacking>
but this configuration remains invalid:
<memoryBacking>
<hugepages>
<page size='2048' unit='KiB' nodeset='0'/>
<page size='1048576' unit='KiB'/>
</hugepages>
</memoryBacking>
The issue with the second configuration is that it was originally
working, however changing the order of the <page> elements resolved
into using different page size for the guest. The code is written
in a way that it expect only one page configured and always uses only
the first page in case that there is no guest NUMA topology configured.

The virCapsDomainDataCompare() method is used for filtering out
candidates which don't match the desired criteria. It is called
primarily from the innermost loops and as such is doing many repeated
checks. For example if architcture and os type were checked at the top
level loop the two inner loops could be avoided entirely. If emulator
and domain type were checked in the 2nd level loop the 3rd level loop
can be avoided too.
This change thus removes the virCapsDomainDataCompare() method and puts
suitable checks at the start of each loop to ensure it executes the
minimal number of loop iterations possible. The code becomes clearer to
understand as a nice side-effect.

Fix regression introduced in <42fd5a58adb>. With q35 machine type which

it's called per-disk.
Move the call back after formatting all disks and reiterate the disks to
find the floppy controllers.
This also moves the '-global' directive which sets up the default

It is increasingly likely that some distro is going to change the
default "x86" machine type in QEMU from "pc" to "q35". This will
certainly break existing applications which write their XML on the
assumption that it is using a "pc" machine by default. For example they'll
lack a IDE CDROM and get PCIe instead of PCI which changes the topology
radically.
Libvirt promises to isolate applications from hypervisor changes that
may cause incompatibilities, so we must ensure that we always use the
"pc" machine type if it is available. Only use QEMU's own reported
default machine type if "pc" does not exist.
This issue is not x86-only, other arches are liable to change their
default machine, while some arches don't report any default at all
causing libvirt to pick the first machine in the list. Thus to
guarantee stability to applications, declare a preferred default
machine for all architectures we currently support with QEMU.
Note this change assumes there will always be a "pc" alias as long as a
versioned "pc-XXX" machine type exists. If QEMU were to ship a "pc-XXX"
machine type but not provide the "pc" alias, it is too hard to decide
which to default so. Versioned machine types are supposed to be
considered opaque strings, so we can't apply any sensible ordering
ourselves and QEMU isn't reporting the list of machines in any sensible
ordering itself.

The jansson and json-glib libraries both export symbols with a json_
name prefix and json_object_iter_next() clashes between them.
Unfortunately json-glib is linked in by GTK, so any app using GTK and
libvirt will get a clash, resulting in SEGV. This also affects the NSS
module provided by libvirt
Instead of directly linking to jansson, use dlopen() with the RTLD_LOCAL
flag which allows us to hide the symbols from the application that loads
libvirt or the NSS module.
Some preprocessor black magic and wrapper functions are used to redirect
calls into the dlopen resolved symbols.

Commit id fca9afa08 changed the @req->ifname to use
@req->binding->portdevname fillingin the @req->binding
in a similar way that @req->ifname would have been
filled in during virNWFilterDHCPSnoopReq processing.
However, in doing so it did not take into account some
code paths where the @req->binding should be checked
instead of @req->binding->portdevname. These checks
led to SEGVs in some cases during libvirtd reload
processing in virNWFilterSnoopRemAllReqIter (for
stop during nwfilterStateCleanup processing) and
virNWFilterSnoopReqLeaseDel (for start during
nwfilterStateInitialize processing).
In particular, when reading the nwfilter.leases file
a new @req is created, but the @req->binding is not
filled in. That's left to virNWFilterDHCPSnoopReq
processing which checks if the @req already exists
in the @virNWFilterSnoopState.snoopReqs hash table
after adding a virNWFilterSnoopState.ifnameToKey
entry for the @req->binding->portdevname by a
@ref->ikey value.
NB: virNWFilterSnoopIPLeaseInstallRule and
virNWFilterDHCPSnoopThread do not need the
req->binding check since they can only be called
after the filter->binding is created/assigned.

Consider creating a listener socket from a hostname that resolves to
multiple addresses. It might be the case that the hostname resolves to
both an IPv4 and IPv6 address because it is reachable over both
protocols, but the IPv6 connectivity is provided off-host. In such a
case no local NIC will have IPv6 and so bind() would fail with the
EADDRNOTAVAIL errno. Thus it should be treated as non-fatal as long as
at least one socket was succesfully bound.

When attaching a device to the domain we need to be sure
to use the correct domain definition (vm->def or vm->newDef)
when calling virDomainDeviceDefParse because the post parse
processing algorithms that may assign an address for the
device will use whatever domain definition was passed in.
Additionally, some devices (SCSI hostdev and SCSI disk) use
algorithms that rely on knowing what already exists of the
other type when generating the new device's address. Using
the wrong VM definition could result in duplicated addresses.
In the case of the bz, two hostdev's with no domain address
provided were added to the running domain's config only.
However, the parsing algorithm used the live domain in
order to figure out the host device address resulting in
the same address being used and a subsequent start failing
due to duplicate address.
Fix this by separating the checks/code into CONFIG and LIVE
processing using the correct definition for each block and
performing cleanup for both options as necessary.

When doing a memory snapshot qemuOpenFile() is used. This means
that the file where memory is saved is firstly attempted to be
created under root:root (because that's what libvirtd is running
under) and if this fails the second attempt is done under
domain's uid:gid. This does not make much sense - qemu is given
opened FD so it does not need to access the file. Moreover, if
dynamicOwnership is set in qemu.conf and the file lives on a
squashed NFS this is deadly combination and very likely to fail.
The fix consists of using:
qemuOpenFileAs(fallback_uid = cfg->user,
fallback_gid = cfg->group,
dynamicOwnership = false)
In other words, dynamicOwnership is turned off for memory
snapshot (chown() will still be attempted if the file does not
live on NFS) and instead of using domain DAC label, configured
user:group is set as fallback.

Currently, the functions return a pointer to the

Not only does this kind of error handling look quite

return zero on success and a negative int on failure,

The strncpy() function has this quirk where it will copy
*up* to the requested number of bytes, that is, it will
stop early if it encounters a NULL byte in the source
string.
This makes it legal to pass the size of the destination
buffer (minus one byte needed for the string terminator)
as the number of bytes to copy and still get something
somewhat reasonable out of the operation; unfortunately,
it also makes the function difficult to reason about
and way too easy to misuse.
We want to move away from the way strncpy() behaves and
towards better defined semantics, where virStrncpy()
will always copy *exactly* the number of bytes it's
been asked to copy; before we can do that, though, we
have to change a few of the callers.

While qemu supports the 'transaction' command since v1.1.0
(52e7c241ac766406f05fa) and the 'blockdev-snapshot-sync' command since
v0.14.0-rc0 we need to keep the capability bits present since some qemu
downstreams (RHEL/CentOS 7 for example) chose to cripple qemu by
arbitrarily compiling out some stuff which was already present at that
time.
To simplify the crazy code just require both commands to be present at
the beginning of an external snapshot so that we can remove the case when
'transaction' would not be supported.
This also allows to drop any logic connected to the
VIR_DOMAIN_SNAPSHOT_CREATE_ATOMIC flag since snapshots are atomic with
the 'transaction' command.

Historically, we've always enabled an emulated video device every time we

Since QEMU 2.12, QEMU understands a new vfio-pci device option 'display'
which can be used to turn on display capabilities on vgpu-enabled
mediated devices, IOW emulated GPU devices like QXL will no longer be
needed with vgpu-enable mdevs.
QEMU defaults to 'auto' for the 'display' attribute, which is not
foolproof, so we need to play it safe here and default to display='off'
if this attribute wasn't provided in the XML explicitly.

QEMU 2.12 introduced a new type of display for mediated devices using
vfio-pci backend which allows a mediated device to be used as a VGA
compatible device as an alternative to an emulated video device. QEMU
exposes this feature via a vfio device property 'display' with supported
values 'on/off/auto' (libvirt will default to 'off').
This patch adds the necessary bits to domain config handling in order to
expose this feature. Since there's no convenient way for libvirt to come
up with usable defaults for the display setting, simply because libvirt
is not able to figure out which of the display implementations - dma-buf
which requires OpenGL support vs vfio regions which doesn't need OpenGL
(works with OpenGL enabled too) - the underlying mdev uses.

Since 2.10 QEMU supports a new display type egl-headless which uses the
drm nodes for OpenGL rendering copying back the rendered bits back to
QEMU into a dma-buf which can be accessed by standard "display" apps
like VNC or SPICE. Although this display type can be used on its own,
for any practical use case it makes sense to pair it with either VNC or
SPICE display. The clear benefit of this display is that VNC gains
OpenGL support, which it natively doesn't have, and SPICE gains remote
OpenGL support (native OpenGL support only works locally through a UNIX
socket, i.e. listen type=socket/none).

AMD x86 CPUs have two separate ways to mitigate the Speculative Store
Bypass hardware flaw. In current processors only non-architectural MSRs
are available, and so hypervisors must expose a virtualized MSR and CPU
flag "virt-ssbd" (CPUID Function 8000_0008, EBX[25]=1).
In future processors AMD will provide an architectural MSR, indicated by
existance of the CPUID Function 8000_0008, EBX[24]=1, to which QEMU has
given the name "amd-ssbd".
The "amd-ssbd" flag should be used in preference to "virt-ssbd", if it
is available, since it provides improved performance. For virtual
machine configuration, both should be exposed when available, to allow
for maximal guest OS compatibility as not all guests yet support both.
If future processes are not vulnerable to the flaw, this will be
indicated by the existance of CPUID Function 8000_0008, EBX[26]=1,
to which QEMU has given the name "amd-no-ssb".
See also 124441_AMD64_SpeculativeStoreBypassDisable_Whitepaper_final.pdf
from:
https://bugzilla.kernel.org/show_bug.cgi?id=199889
Note that neither amd-ssbd or amd-no-ssb will be reported by the kernel

but doesn't report their existance as distinct flags in /proc/cpuinfo.

When libvirtd is restarted, it checks that each guest tap device is
still attached to the bridge device that the configuration info says
it should be connected to. If not, the tap will be disconnected from
[wherever it is] and connected to [wherever it should be].
The previous code that did this did not account for:
1) the IFLA_MASTER attribute in a netdev's ifinfo will be set to
"ovs-system" for any tap device connected to an OVS bridge, *not*
to the name of the bridge it is attached to.
2) virNetDevRemovePort() only works for devices that are attached to a
standard Linux host bridge. If a device is currently attached to an
OVS bridge, then virNetDevOpenvswitchRemovePort() must be called
instead.
This patch remedies those problems, and adds a couple of information

Once we called qemuDomainObjEnterRemote to talk to the destination
daemon during a peer to peer migration, the vm lock is released and we
only hold an async job. If the source domain dies at this point the
monitor EOF callback is allowed to do its job and (among other things)
clear all private data irrelevant for stopped domain. Thus when we call
qemuDomainObjExitRemote, the domain may already be gone and we should
avoid touching runtime private data (such as current job info).
In other words after acquiring the lock in qemuDomainObjExitRemote, we
need to check the domain is still alive. Unless we're doing offline
migration.

Starting with QEMU 2.9, encryption convert processing requires
a multi-step process in order to generate an encrypted image from
some non encrypted raw image.
Processing requires to first create an encrypted image using the
sizing parameters from the input source and second to use the
--image-opts, -n, and --target-image-opts options along with inline
driver options to describe the input and output files, generating
two commands such as:
$ qemu-img create -f luks \
--object secret,id=demo.img_encrypt0,file=/path/to/secretFile \
-o key-secret=demo.img_encrypt0 \
demo.img 500K
Formatting 'demo.img', fmt=luks size=512000 key-secret=demo.img_encrypt0
$ qemu-img convert --image-opts -n --target-image-opts \
--object secret,id=demo.img_encrypt0,file=/path/to/secretFile \
driver=raw,file.filename=sparse.img \
driver=luks,file.filename=demo.img,key-secret=demo.img_encrypt0
$
This patch handles the convert processing by running the processing
in a do..while loop essentially reusing the existing create logic and
arguments to create the target vol from the inputvol and then converting
the inputvol using new arguments.
This then allows the following virsh command to work properly:
virsh vol-create-from default encrypt1-luks.xml data.img --inputpool default
where encrypt1-luks.xml would provided the path and secret for
the new image, while data.img would be the source image.

If there's a long running job it might cause us to wait 30
seconds before we give up acquiring the job. This is problematic
to interactive applications that fetch stats repeatedly every few

xenParsePCI() does a lot of stuff and, in order to make things cleaner,
let's split it in two new functions:
- xenParsePCI(): it's a new function that keeps the old name. It's
responsible for the whole per-PCI logic from the old xenParsePCI();
- xenParsePCIList(): it's basically the old xenParsePCI(), but now it
just iterates over the list of PCIs, calling xenParsePCI() per each PCI.

TSEG (Top of Memory Segment) is one of many regions that SMM (System Management

lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG. The difference to the TSEG implemented in real q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments. Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here. Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message

we changed a switch in the nwfilter learning thread so that it had
explict cases for all enum entries. Unfortunately the parameters in the
method had been declared with incorrect type. The "howDetect" parameter
does *not* accept "enum howDetect" values, rather it accepts a bitmask
of "enum howDetect" values, so it should have been an "int" type.
The caller always passes DETECT_STATIC|DETECT_DHCP, so essentially the
IP addressing learning was completely broken by the above change, as it
never matched any switch case, hitting the default leading to EINVAL.
Stop using a typedef for the parameter name this this is a bitmask,
not a plain enum value. Also stop using switch() since that's misleading
with bitmasks too.

This patch adds support for an external swtpm TPM emulator. The XML for
this type of TPM looks as follows:
<tpm model='tpm-tis'>
<backend type='emulator'/>
</tpm>
The XML will currently only start a TPM 1.2.
Upon first start, libvirt will run `swtpm_setup`, which will simulate the
manufacturing of a TPM and create certificates for it and write them into
NVRAM locations of the emulated TPM.
After that libvirt starts the swtpm TPM emulator using the `swtpm` executable.
Once the VM terminates, libvirt uses the swtpm_ioctl executable to gracefully
shut down the `swtpm` in case it is still running (QEMU did not send shutdown)
or clean up the socket file.
The above mentioned executables must be found in the PATH.
The executables can either be run as root or started as root and switch to
the tss user. The requirement for the tss user comes through 'tcsd', which
is used for the simulation of the manufacturing. Which user is used can be
configured through qemu.conf. By default 'tss' is used.
The swtpm writes out state into files. The state is kept in /var/lib/libvirt/swtpm:
[root@localhost libvirt]# ls -lZ | grep swtpm
drwx--x--x. 7 root root unconfined_u:object_r:virt_var_lib_t:s0 4096 Apr 5 16:22 swtpm
The directory /var/lib/libvirt/swtpm maintains per-TPM state directories.
(Using the uuid of the VM for that since the name can change per VM renaming but
we need a stable directory name.)

Implement functions for managing the storage of the external swtpm as well
as starting and stopping it. Also implement functions to use swtpm_setup,
which simulates the manufacturing of a TPM, which includes creation of
certificates for the device.
Further, the external TPM needs storage on the host that we need to set
up before it can be run. We can clean up the host once the domain is
undefined.
This patch also implements a small layer for external device support that
calls into the TPM device layer if a domain has an attached TPM. This is
the layer we will wire up later on.

QEMU guest agent support
there was code that would loop and retry the connection when opening
the agent socket. At this time, the only thing done in between the
opening of the monitor socket & opening of the agent socket was a
call to set the monitor capabilities. This was a no-op on non-QMP
versions, so in theory there could be a race which let us connect
to the monitor while the agent socket was still not created by QEMU.
In the modern world, however, we long ago mandated the use of QMP
for managing QEMU, so we're guaranteed to have a set capabilities
QMP call. Once we've seen a reply to this, we're guaranteed that
QEMU has fully initialized all backends and is in its event loop.
We can thus be sure the QEMU agent socket is present and don't need
to retry connections to it, even without having the chardev FD passing
feature.

Since libvirt called bind() and listen() on the UNIX socket, it is
guaranteed that connect() will immediately succeed, if QEMU is running
normally. It will only fail if QEMU has closed the monitor socket by
mistake or if QEMU has exited, letting the kernel close it.
With this in mind we can remove the retry loop and timeout when
connecting to the QEMU monitor if we are doing FD passing. Libvirt can
go straight to sending the QMP greeting and will simply block waiting
for a reply until QEMU is ready.

There is a race condition when spawning QEMU where libvirt has spawned
QEMU but the monitor socket is not yet open. Libvirt has to repeatedly
try to connect() to QEMU's monitor until eventually it succeeds, or
times out. We use kill() to check if QEMU is still alive so we avoid
waiting a long time if QEMU exited, but having a timeout at all is still
unpleasant.
With QEMU 2.12 we can pass in a pre-opened FD for UNIX domain or TCP
sockets. If libvirt has called bind() and listen() on this FD, then we
have a guarantee that libvirt can immediately call connect() and
succeed without any race.
Although we only really care about this for the monitor socket and agent
socket, this patch does FD passing for all UNIX socket based character
devices since there appears to be no downside to it.
We don't do FD passing for TCP sockets, however, because it is only
possible to pass a single FD, while some hostnames may require listening
on multiple FDs to cover IPv4 and IPv6 concurrently.

Libvirt relies on being able to kill the destination domain and resume
the source one during migration until we called "cont" on the
destination. Unfortunately, QEMU automatically activates block devices
at the end of migration even when it's called with -S. This wasn't a big
issue in the past since the guest is not running and thus no data are
written to the block devices. However, when QEMU introduced its internal
block device locks, we can no longer resume the source domain once the
destination domain already activated the block devices (and thus
acquired all locks) unless the destination domain is killed first.
Since it's impossible to synchronize the destination and the source
libvirt daemons after a failed migration, QEMU introduced a new
migration capability called "late-block-activate" which ensures QEMU
won't activate block devices until it gets "cont". The only thing we
need to do is to enable this capability whenever QEMU supports it.

What is even worse is that we do not look up capabilities for
parsed emulator path rather some generic capabilities for parsed
arch. Therefore, if emulator points to qemu under non-default
path (say $HOME/qemu-system-arm) but there's no such qemu under

Per-domain log files were introduced in commit a30b08b717. The FILE
objects associated with these log files are stored in a hash table
using domid as a key. When a domain is shutdown, destroyed, or
otherwise powered-off, the FILE object is removed from the hash table,
where the free function will close the FILE.
Unfortunately the call to remove the FILE from the hash table occurs
after setting domid=-1 in the libxlDomainCleanup() function. The
object is never removed from the hash table, the free function is
never called, and the underlying fd is leaked. Fix by removing the
FILE object from the hash table before setting domid=-1.

In commit 8bebb2b735 I've refactored how the detach of disk with a
managed persistent reservations object is handled. After the commit if
any disk with a managed PR object would be removed libvirt would also
attempt to remove the shared 'pr-manager-helper' object potentially used
by other disks.
Thankfully this should not have practical impact as qemu should reject
deletion of the object if it was still used and the rest of the code is
correct.
Fix this by removing the disk from the definition earlier and checking
if the shared/managed pr-manager-helper object is still needed.
This basically splits the detach code for the managed PR object from the
unmanaged ones. The same separation will follow for the attachment code
as well as it greatly simplifies -blockdev support for this.

While RPM recorded 644 mode for the XMLs, libvirt saves them with 600

In order to avoid a possible error as a result of kernel interactions
with the partition helper, let's use virWaitForDevices to force things
to settle down before attempting to open and read the partition. This
is related to https://bugzilla.redhat.com/show_bug.cgi?id=1264719.
Although perhaps overkill to have too many places to settle, since
we know that the act of reading the partitions via libvirt_parthelper
will cause udev activity/events - we just need to ensure udev has
been settled before proceding with usage of the device.

Before we generate the command line for qemu, if the domain about to
be launched desires to utilize the VM Generation ID functionality, then
handle both the regenerating the GUID value for backup recovery (restore

Add the query of the device objects for the vmgenid device
Signed-off-by: John Ferlan <jferlan@redhat.com>
ACKed-by: Michal Privoznik <mprivozn@redhat.com>
The VM Generation ID is a mechanism to provide a unique 128-bit,
cryptographically random, and integer value identifier known as
the GUID (Globally Unique Identifier) to the guest OS. The value
is used to help notify the guest operating system when the virtual
machine is executed with a different configuration.
This patch adds support for a new "genid" XML element similar to
the "uuid" element. The "genid" element can have two forms "<genid/>"
or "<genid>$GUID</genid>". If the $GUID is not provided, libvirt
will generate one and save it in the XML.
Since adding support for a generated GUID (or UUID like) value to
be displayed modifying the xml2xml test to include virrandommock.so
is necessary since it will generate a "known" value.

Some AMD processors only support a non-architectural means of
enabling Speculative Store Bypass Disable. To allow simplified
handling in virtual environments, hypervisors will expose an
architectural definition through CPUID bit 0x80000008_EBX[25].
This needs to be exposed to guest OS running on AMD x86 hosts to
allow them to protect against CVE-2018-3639.
Note that since this CPUID bit won't be present in the host CPUID
results on physical hosts, it will not be enabled automatically
in guests configured with "host-model" CPU unless using QEMU
version >= 2.9.0. Thus for older versions of QEMU, this feature

QEMU has this new feature memory-backend-file.discard-data=yes
which is a nifty optimization. Basically, when qemu is quitting
or on memory hotplug it calls munmap() and close() on the file
that is backing the memory. However, this does not mean kernel
won't stop touching that part of memory. It still might. With
this feature enabled we tell kernel: "we don't need this memory
nor data stored in it". This makes kernel drop the memory
immediately without trying to sync memory with the mapped file.
Unfortunately, this cannot be turned on by default because we
can't be sure when users really don't care about what happens to
data after qemu dies. So it has to be opt-in. As usual, there are
three places where one can configure memory attributes. This
patch adds the feature to all of them.

Rather than specialcasing handling of the '*' character, use fnmatch()
to get normal shell wildcard syntax, as described in 'man glob(7)'.
To get an indication of the performance impact of using globs instead
of plain string matches, a test program was written. The list of all
260 log categories was extracted from the source. Then a typical log
filters setup was picked by creating an array of the strings "qemu",
"security", "util", "cgroup", "event", "object". Every filter string
was matched against every log category. Timing information showed that
using strstr() this took 8 microseconds, while fnmatch() took 114
microseconds.
IOW, fnmatch is 14 times slower than our existing strstr check. These
numbers show a worst case scenario that will never be hit, because it
is rare that every log category would have data output. The log category
matches are cached, so each category is only checked once no matter how
many log statements are emitted. IOW despite being slower, this will
be lost in the noise and have no consequence on real world logging
performance.

When adding a new object to the domain object list, there should
have been 2 virObjectRef calls made one for each list into which
the object was placed to match the 2 virObjectUnref calls that
would occur during Remove as part of virHashRemoveEntry when
virObjectFreeHashData is called when the element is removed from
the hash table as set up in virDomainObjListNew.
Some drivers (libxl, lxc, qemu, and vz) handled this inconsistency
by calling virObjectRef upon successful return from virDomainObjListAdd
in order to use virDomainObjEndAPI when done with the returned @vm.
While others (bhyve, openvz, test, and vmware) handled this via only
calling virObjectUnlock upon successful return from virDomainObjListAdd.
This patch will "unify" the approach to use virDomainObjEndAPI
for any @vm successfully returned from virDomainObjListAdd.
Because list removal is so tightly coupled with list addition,
this patch fixes the list removal algorithm to return the object
as entered - "locked and reffed". This way, the callers can then
decide how to uniformly handle add/remove success and failure.
This removes the onus on the caller to "specially handle" the
@vm during removal processing.
The Add/Remove logic allows for some logic simplification such
as in libxl where we can Remove the @vm directly rather than
needing to set a @remove_dom boolean and removing after the
libxlDomainObjEndJob completes as the @vm is locked/reffed.

When an nwfilter rule sets the parameter CTRL_IP_LEARNING to "dhcp",
this turns on the "dhcpsnoop" thread, which uses libpcap to monitor
traffic on the domain's tap device and extract the IP address from the
DHCP response.
If libpcap on the host is built with HAVE_TPACKET3 defined (to enable
support for TPACKET_V3), the dhcpsnoop code's initialization of the
libpcap socket would fail with the following error:
virNWFilterSnoopDHCPOpen:1134 : internal error: pcap_setfilter: can't remove kernel filter: Bad file descriptor
It turns out that this was because TPACKET_V3 requires a larger buffer
size than libvirt was setting (we were setting it to 128k). Changing
the buffer size to 256k eliminates the error, and the dhcpsnoop thread
once again works properly.
A fuller explanation of why TPACKET_V3 requires such a large buffer,
for future git spelunkers:
libpcap calls setsockopt(... SOL_PACKET, PACKET_RX_RING...) to setup a
ring buffer for receiving packets; two of the attributes sent to this
API are called tp_frame_size, and tp_frame_nr. If libpcap was built
with HAVE_TPACKET3 defined, tp_trame_size is set to MAXIMUM_SNAPLEN
(defined in libpcap sources as 262144) and tp_frame_nr is set to:
[the buffer size we set, i.e. PCAP_BUFFERSIZE i.e. 262144] / tp_frame_size.
So if PCAP_BUFFERSIZE < MAXIMUM_SNAPLEN, then tp_frame_nr (the number
of frames in the ring buffer) is 0, which is nonsensical. This same
value is later used as a multiplier to determine the size for a call
to malloc() (which would also fail).
(NB: if HAVE_TPACKET3 is *not* defined, then tp_frame_size is set to
the snaplen set by the user (in our case 576) plus a small amount to
account for ethernet headers, so 256k is far more than adequate)
Since the TPACKET_V3 code in libpcap actually reads multiple packets
into each frame, it's not a problem to have only a single frame
(especially when we are monitoring such infrequent traffic), so it's
okay to set this relatively small buffer size (in comparison to the
default, which is 2MB), which is important since every guest using
dhcp snooping in a nwfilter rule will hold 2 of these buffers for the
entire life of the guest.
Thanks to Christian Ehrhardt for discovering that buffer size was the
problem (this was not at all obvious from the error that was logged!)
