ca437d0603 qemu: Refuse partitions in disk targets
The way in which the qemu driver generates aliases for disks involves
ignoring the partition number part of a target dev name.  This means that
all partitions of a block device and the device itself all end up with the
same alias.  If multiple such disks are specified in XML, the resulting
name clash makes qemu invocation fail.

Since attaching partitions to qemu VMs doesn't seem to make much sense
anyway, disallow partitions in target specifications altogether.

76d31244c5 rpc: fix escaping of shell path for netcat binary
Consider having a nc binary in the path with a space in its name,
for example '/tmp/fo o/nc'

This results in libvirt running SSH with the following arg value

  "'if ''/tmp/fo o/nc'' -q 2>&1 | grep \"requires
    an argument\" >/dev/null 2>&1; then ARG=-q0;
    else ARG=;fi;''/tmp/fo o/nc'' $ARG -U
    /var/run/libvirt/libvirt-sock'"

The use of the single quote escaping was introduced by

  commit 6ac6238de3
  Author: Guido Günther <agx@sigxcpu.org>
  Date:   Thu Oct 13 21:49:01 2011 +0200

    Use virBufferEscapeShell in virNetSocketNewConnectSSH

    to escape the netcat command since it's passed to the shell. Adjust
    expected test case output accordingly.

While the intention of this change was good, the result is broken as it
is still underquoted.

On the SSH server side, SSH itself runs the command via the shell.
Our command is then invoking the shell again. Thus we see

$ virsh -c qemu+ssh://root@domokun/system?netcat=%2Ftmp%2Ffo%20o%2Fnc list
error: failed to connect to the hypervisor
error: End of file while reading data: sh: /tmp/fo: No such file or directory: Input/output error

With the second level of escaping added we can now successfully use a nc
binary with a space in the path.

The original test case added was misleading as it illustrated using a
binary path of 'nc -4' which is not a path, it is a command with a
separate argument, which is getting interpreted as a path.

      qemu: add qemuDomainVideoPrivate

Since the test suite does not invoke qemuExtDevicesStart(), no
vhost_user_fd will be present when generating test XML. To deal
with this we can must a fake FD number. While the current XML
is using FD == 0, we pick a very interesting number that's unlikely
to be a real FD, so that we're more likely to see any mistakes
closing the invalid FD.

There is one hack hidden here, but since this is in a test, it's
okay. In order to get a list of expected firmwares in
virFirmwarePtr form I'm using virFirmwareParseList(). But
usually, in real life scenario, this function is used only to
parse a list of UEFI images which have NVRAM split out. In other
words, this function expects ${FW}:${NVRAM} pairs. But in this
test, we also want to allow just a single path: ${FW} because
some reported firmwares are just a BIOS image really. To avoid
writing some parser function, let's just pass "NULL" as ${NVRAM}
and fix the result later.

78f8769a84 qemu_firmware: Extend qemuFirmwareGetSupported to return FW paths
The qemuFirmwareGetSupported() function is called from qemu
driver to generate domain capabilities XML based on FW descriptor
files. However, the function currently reports only some features
from domcapabilities XML and not actual FW image paths. The paths
reported in the domcapabilities XML are still from pre-FW
descriptor era and therefore the XML might be a bit confusing.
For instance, it may say that secure boot is supported but
secboot enabled FW is not in the listed FW image paths.

To resolve this problem, change qemuFirmwareGetSupported() so
that it also returns a list of FW images (we have the list
anyway). Luckily, we already have a structure to represent a FW
image - virFirmware.

so now build using this script to run against an uninstalled tree we

7cd0911e1a qemu: support unmanaged target tap dev for <interface type='ethernet'>
If managed='no', then the tap device must already exist, and setting
of MAC address and online status (IFF_UP) is skipped.

NB: we still set IFF_VNET_HDR and IFF_MULTI_QUEUE as appropriate,
because those bits must be properly set in the TUNSETIFF we use to set
the tap device name of the handle we've opened - if IFF_VNET_HDR has
not been set and we set it the request will be honored even when
running libvirtd unprivileged; if IFF_MULTI_QUEUE is requested to be
different than how it was created, that will result in an error from
the kernel. This means that you don't need to pay attention to
IFF_VNET_HDR when creating the tap devices, but you *do* need to set
IFF_MULTI_QUEUE if you're going to use multiple queues for your tap
device.

NB2: /dev/vhost-net normally has permissions 600, so it can't be
opened by an unprivileged process. This would normally cause a warning
message when using a virtio net device from an unprivileged
libvirtd. I've found that setting the permissions for /dev/vhost-net
permits unprivileged libvirtd to use vhost-net for virtio devices, but
have no idea what sort of security implications that has. I haven't
changed libvrit's code to avoid *attempting* to open /dev/vhost-net -
if you are concerned about the security of opening up permissions of
/dev/vhost-net (probably a good idea at least until we ask someone who
knows about the code) then add <driver name='qemu'/> to the interface
definition and you'll avoid the warning message.

Note that virNetDevTapCreate() is the correct function to call in the
case of an existing device, because the same ioctl() that creates a
new tap device will also open an existing tap device.

77f72a8615 conf: new "managed" attribute for target dev of <interface type='ethernet'>
Although <interface type='ethernet'> has always been able to use an
existing tap device, this is just a coincidence due to the fact that
the same ioctl is used to create a new tap device or get a handle to
an existing device.

Even then, once we have the handle to the device, we still insist on
doing extra setup to it (setting the MAC address and IFF_UP).  That
*might* be okay if libvirtd is running as a privileged process, but if
libvirtd is running as an unprivileged user, those attempted
modifications to the tap device will fail (yes, even if the tap is set
to be owned by the user running libvirtd). We could avoid this if we
knew that the device already existed, but as stated above, an existing
device and new device are both accessed in the same manner, and
anyway, we need to preserve existing behavior for those who are
already using pre-existing devices with privileged libvirtd (and
allowing/expecting libvirt to configure the pre-existing device).

In order to cleanly support the idea of using a pre-existing and
pre-configured tap device, this patch introduces a new optional
attribute "managed" for the interface <target> element. This
attribute is only valid for <interface type='ethernet'> (since all
other interface types have mandatory config that doesn't apply in the
case where we expect the tap device to be setup before we
get it). The syntax would look something like this:

   <interface type='ethernet'>
      <target dev='mytap0' managed='no'/>
      ...
   </interface>

This patch just adds managed to the grammar and parser for <target>,
but has no functionality behind it.

(NB: when managed='no' (the default when not specified is 'yes'), the
target dev is always a name explicitly provided, so we don't
auto-remove it from the config just because it starts with "vnet"
(VIR_NET_GENERATED_TAP_PREFIX); this makes it possible to use the
same pattern of names that libvirt itself uses when it automatically
creates the tap devices.)

2d9b8acf58 virpcimock.c: simplify getrealpath() usage
Previous patch had to add '/sys/kernel/' prefix in opendir() because
the path, which is being mocked, wasn't being considered due to
an 'if SYSFS_PCI_PREFIX' guarding the call to getrealpath().

In fact, all current getrealpath() callers are guarding it with a
conditional to ensure that the function will never be called with
a non-mocked path. In this case, an extra non-NULL verification is
needed for the 'newpath' string to use the variable - which is
counterintuitive, given that getrealpath() will always write the
'newpath' string in any non-error conditon.

However, simply removing the guard of all getrealpath() instances
causes an abort in init_env(). This happens because tests will
execute access() to non-mocked paths even before the
LIBVIRT_FAKE_ROOT_DIR variable is declared in the test files. We
don't need 'fakerootdir' to be created at this point though.

This patch does the following changes to simplify getrealpath()
usage:

- getrealpath() will now guard the init_env() call by checking if
both fakeroot isn't created and the required path is being mocked.
This ensures that we're not failing inside init_env() because
we're too early and LIBVIRT_FAKE_ROOT_DIR wasn't defined yet;

- remove all conditional guards to call getrealpath() from
access(), virMockStatRedirect(), open(), open_2(), opendir()

we're mocking, making it easier to add/remove them. If a prefix

944a35d7f0 tests: Add test case for QEMU pci-hostdev hotplug
This patch adds hostdev test cases in qemuhotplugtest.c.

Note: the small tweak inside virpcimock.c was needed because
the new tests added a code path in which virHostHasIOMMU()
(virutil.c) started being called, and the mocked '/sys/kernel/'
prefix that is mocked in virpcimock.c wasn't being considered
in the opendir() mock. An alternative to avoid these situations
in virpcimock.c is implemented in the next patch.

The multifunction PCI devices dont have 'physfn' softlinks.

The patch adds few Virtual functions to the mock environment and
changes the existing VFIO test xmls using the VFs to use the newly

9f90a4bfb4 qemu: maintain user alias for video type 'none'
After parsing a video device with a model type of
VIR_DOMAIN_VIDEO_TYPE_NONE, all device info is cleared (see
virDomainDefPostParseVideo()) in order to avoid formatting any
auto-generated values for the XML. Subsequently, however, an alias is
generated for the video device (e.g. 'video0'), which results in an
alias property being formatted in the XML output anyway. This creates
confusion if the user has explicitly provided an alias for the video
device since the alias will change.

To avoid this, don't clear the user-defined alias for video devices of
type "none".

fefc4ff4cd tests: Use flat namespace on macOS
Test executables and mocks have assumption that any symbol can be
replaced with LD_PRELOAD. That's not a case for macOS unless flat
namespace is used, because every external symbol reference records the
library to be looked up. And the symbols cannot be replaced unless dyld
interposing is used.

Setting DYLD_FORCE_FLAT_NAMESPACE changes symbol lookup behaviour to be
similar to Linux dynamic linker. It's more lightweight solution than
explicitly decorating all mock symbols as interpositions and building
libvirt as interposable dynamic library.

This fixes vircryptotest and allows to proceed other tests that rely on

e8b8d96e2b virpcimock: Don't create "pci-stub" driver
Now that nothing supports "pci-stub" driver (aka KVM style of PCI
device assignment) there is no need for virpcimock to create it.

The KVM assignment was removed in qemu driver in previous commit.
Remove it from domaincapstest too which is hard coding it.

80b58a7c1a qemu: Drop KVM assignment
KVM style of PCI devices assignment was dropped in kernel in
favor of vfio pci (see kernel commit v4.12-rc1~68^2~65). Since
vfio is around for quite some time now and is far superior
discourage people in using KVM style.

Ideally, I'd make QEMU_CAPS_VFIO_PCI implicitly assumed but turns
out qemu-3.0.0 doesn't support vfio-pci device for RISC-V.

7cfb7aab57 security_util: Remove stale XATTRs
It may happen that we leave some XATTRs behind. For instance, on
a sudden power loss, the host just shuts down without calling
restore on domain paths. This creates a problem, because when the
host starts up again, the XATTRs are there but they don't reflect
the true state and this may result in libvirt denying start of a
domain.

To solve this, save a unique timestamp (host boot time) among
with our XATTRs.

51da92f418 conf: resctrl object is not properly handled
resctrl object stored in def->resctrls is shared by cachetune and
memorytune. The domain xml configuration is parsed firstly for
cachetune then memorytune, and the resctrl object will not be created
in parsing settings for memorytune once it found sharing exists.

But resctrl is improperly freed when sharing happens.

c46ab0d48f tests: don't try to mock __open_2 on non-GLibc builds
Mocking of the __open_2 function was added in

  commit 459f071cac
  Author: Michal Privoznik <mprivozn@redhat.com>
  Date:   Thu Aug 15 16:37:17 2019 +0200

    virpcimock: Mock __open_2()

This function only exists in glibc, however, and the mocking code runs
on systems not using glibc, such as FreeBSD. Even Linux hosts might be
using a different libc impl, though we don't actively try to support
that.

9f3b5f89d4 qemu: add support for Direct Mode for Hyper-V Synthetic timers
QEMU-4.1 supports 'Direct Mode' for Hyper-V synthetic timers
(hv-stimer-direct CPU flag): Windows guests can request that timer
expiration notifications are delivered as normal interrupts (and not
VMBus messages). This is used by Hyper-V on KVM.
