5ae24a13c7 Revert "dbus: correctly build reply message"
This reverts commit 39dded7bb6.

This commit broke virpolkittest on Ubuntu 18 which has an old
dbus (v1.12.2). Any other distro with the recent one works
(v1.12.16) which hints its a bug in dbus somewhere. Revert the
commit to stop tickling it.

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.)

4ef4ba4974 tests: Add a baseline test for multifunction pci device use case
There are already good number of test cases with hostdevices,
few have multifunction devices but none having more than one
than one multifunction cards.

This patch adds a case where there are two multifunction cards
and two Virtual functions part of the same XML.

0001:01:00.X & 0005:09:00.X - are Multifunction PCI cards.
0000:06:12.[5|6] - are SRIOV Virtual functions

Future commits will improve on automatically detecting the
multifunction cards and auto-assinging the addresses
appropriately.

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()
and virFileCanonicalizePath(). As a bonus, remove all ternary
conditionals with 'newpath';

- a new 'pathPrefixIsMocked()' helper to aggregate all the prefixes
we're mocking, making it easier to add/remove them. If a prefix
is added inside this function, we can be sure that all functions
are mocking them.

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.

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".

0ae6f5cea5 tests: Avoid gnulib replacements in mocks
gnulib headers change stat, lstat and open to replacement functions,
even for function definitions. This effectively disables standard
library overrides in virfilewrapper and virmockstathelpers since they
are never reached.

Rename the functions and provide a declartion that uses correct
assembler name for the mocks.

This fixes firmware lookup in domaincapstest on macOS.

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
mocks a little bit further.

d6b17edd51 tests: Lookup extended stat/lstat in mocks
macOS syscall interface (/usr/lib/system/libsystem_kernel.dylib) has
three kinds of stat but only one of them can be used to fill
"struct stat": stat$INODE64.

virmockstathelpers looks up regular stat instead of stat$INODE64.  That
causes a failure in qemufirmwaretest because "struct stat" is laid out
differently from the values returned by stat.

Introduce VIR_MOCK_REAL_INIT_ALIASED that can be used to lookup
stat$INODE64 and lstat$INODE64 and use it to setup real functions on
macOS.

c6b3bf9302 tests: Drop /private CWD prefix in commandhelper
/tmp is a symbolic link to /private/tmp on macOS. That causes failures
in commandtest, because getcwd returns /private/tmp and the expected
output doesn't match to "CWD: /tmp".

Rathern than making a copy of commanddata solely for macOS, the /private
prefix is stripped.

647c65186a tests: Remove -module flag for mocks
macOS has two kinds of loadable libraries: MH_BUNDLE, and MH_DYLIB.
bundle is used for plugins that are loaded with dlopen/dlsym/dlclose.
And there's no way to preload a bundle into an application. dynamic
linker (dyld) will reject it when finds it in DYLD_INSERT_LIBRARIES.

Unfortunately, a bundle is built if -module flag is provided to libtool.
The flag has been removed to build dylibs with ".dylib" suffix.

fde361083d tests: Add lib- prefix to all mocks
In preparation libtool "-module" flag removal, add lib prefix to all
mock shared objects.

While at it, introduce VIR_TEST_MOCK macros that makes path out of mock
name to be used with VIR_TEST_PRELOAD or VIR_TEST_MAIN_PRELOAD.  That,
hopefully, improves readability, reduces line length and allows to
tailor VIR_TEST_MOCK for specific platform if it has shared library
suffix different from ".so".

351492e304 tests: Preload mocks with DYLD_INSERT_LIBRARIES on macOS
LD_PRELOAD has no effect on macOS. Instead, dyld(1) provides a way for
symbol hooking via DYLD_INSERT_LIBRARIES. The variable should contain
colon-separated paths to the dylibs to be inserted.

dbb5e20ede tests: Avoid IPv4-translated IPv6 address in sockettest
getnameinfo on macOS formats certain IPv6 addresses as IPv4-translated
addresses. The following pattern has been observed:
  ::ffff is formated as ::0.0.255.255
  ::fffe is formated as ::0.0.255.254
  ::ffff:0 is formated as ::255.255.0.0
  ::fffe:0 is formated as ::255.254.0.0
  ::ffff:0:0 is formated as ::ffff:0.0.0.0
  ::fffe:0:0 is formated as ::fffe:0:0
  ::ffff:0:0:0 is formated as ::ffff:0:0:0

The getnameinfo behavior causes a failure for:
  DO_TEST_PARSE_AND_FORMAT("::ffff", AF_UNSPEC, true);

Use non-ambigious IPv6 for parse/format testing.

0f1b090b0d tests: Don't test octal localhost IP in sockettest on macOS
getaddrinfo on macOS doesn't interpret octal IPv4 addresses. Only
inet_aton can be used for that. Therefore, from macOS standpoint
"0177.0.0.01" is not the same as "127.0.0.1".
