Openstack developers reported that newly-created mdevs were not
recognized by libvirt until after a libvirt daemon restart. The source
of the problem appears to be that when libvirt gets the udev 'add'
event, the sysfs tree for that device might not be ready and so libvirt
waits 100ms for it to appear (max 100 waits of 1ms each). But in the
OpenStack environment, the sysfs tree for new mediated devices was
taking closer to 250ms to appear and therefore libvirt gave up waiting
and didn't add these new devices to its list of nodedevs.
By changing the wait time to 1 second (max 100 waits of 10ms each), this
should provide enough time to enable these deployments to recognize
newly-created mediated devices, but it shouldn't increase the delay for
more traditional deployments too much.

The most recent environment e.g. present in our Fedora Rawhide builds
fail to build the tree with clang with the following error:
../src/util/virhostcpu.c:1291:25: error: field 'header' with variable sized type 'struct kvm_msrs' not at the end of a struct or class is a GNU extension [-Werror,-Wgnu-variable-sized-type-not-at-end]
struct kvm_msrs header;
^
The problem seems to be that clang doesn't like the new way the
'entries' field in struct kvm_msrs is declared.
To work around the issue we can simply allocate the variable dynamically
and use the 'entries' member as it was intended to to access the
members.

Instead of separately building the commandline into a string to log,
just wait a few lines until we've built the virCommand object, and
call virCommandToString, which does the same thing.
(As a bonus, we were already calling virCommandToString to put the
commandline in a string in case of a failure when running it - from
the point of view of *that* usage, we're just moving the call to
virCommandToString *up* a few lines, i.e. we now only construct the
commandline string once.)

Although the next commit will eliminate the one current use of
virFirewallRuleToString(), a future commit will once again have a use
for it, but in a different source file so it will need to be a global
function rather than static. Make that change now so that we don't get
a compile error from having an unused static function in the next
commit.
(The arg list is also changed to include the name of the command as a
separate argument rather than just assuming that it can be derived
from the rule's layer (which is correct for iptables, but won't be
correct for nftables)).

This was a wrapper to call a function in virfirewalld.c that sends an
iptables passthrough rule to firewalld. It hasn't been used in a year
or two, and won't ever be used in the future since passthrough rules
are only supported for iptables, and we've determined that we
shouldn't use iptables passthrough rules.

Similar to the other drivers, virNetworkDriverState now has a
virObject-derived object called virNetworkDriverConfig which is used
for config items.
As a starting point, the directory paths used by the network driver
are moved there (again, parallelling what is done for other drivers).
Using items in virNetworkDriverConfig is (yes, again) similar to using
items in the other drivers' config - anything in the config object is
immutable (once initialized), so the state object only needs to be
locked while getting a reference to the config object, and then the
members of the config object can be safely used until the config
object is unrefed.

The virCommand module is specifically designed so that no caller
has to check for retval of individual virCommand*() APIs except
for virCommandRun() where the actual error is reported. Moreover,
virCommandNew*() use g_new0() to allocate memory and thus it's
not really possible for those APIs to return NULL. Which is why
they are even marked as ATTRIBUTE_NONNULL. But there are few
places where we do check the retval which is a dead code
effectively. Drop those checks.

When multiple VFIO or VDPA devices are assigned to a guest, the guest
can fail to start because the guest fails to map enough memory. For
example, the case mentioned in
https://bugzilla.redhat.com/show_bug.cgi?id=2111317 results in this
failure:
2021-08-05T09:51:47.692578Z qemu-kvm: failed to write, fd=31, errno=14 (Bad address)
2021-08-05T09:51:47.692590Z qemu-kvm: vhost vdpa map fail!
2021-08-05T09:51:47.692594Z qemu-kvm: vhost-vdpa: DMA mapping failed, unable to continue
The current memlock limit calculation does not work for scenarios where
there are multiple such devices assigned to a guest. The root causes are
a little bit different between VFIO and VDPA devices.
For VFIO devices, the issue only occurs when a vIOMMU is present. In
this scenario, each vfio device is assigned a separate AddressSpace
fully mapping guest RAM. When there is no vIOMMU, the devices are all
within the same AddressSpace so no additional memory limit is needed.
For VDPA devices, each device requires the full memory to be mapped
regardless of whether there is a vIOMMU or not.
In order to enable these scenarios, we need to multiply memlock limit
by the number of VDPA devices plus the number of VFIO devices for guests
with a vIOMMU. This has the potential for pushing the memlock limit
above the host physical memory and negating any protection that these
locked memory limits are providing, but there is no other short-term
solution.
In the future, there should be have a revised userspace iommu interface
(iommufd) that the VFIO and VDPA backends can make use of. This will be
able to share locked memory limits between both vfio and vdpa use cases
and address spaces and then we can disable these short term hacks. But
this is still in development upstream.

Xen toolstack has gained basic Virtio support recently which becides
adding various virtio related stuff introduces new disk backend type
LIBXL_DISK_BACKEND_STANDALONE [1].
Unfortunately, this caused a regression in libvirt build with Xen support
enabled, reported by the osstest today [2]:
CC libxl/libvirt_driver_libxl_impl_la-xen_xl.lo
../../src/libxl/xen_xl.c: In function 'xenParseXLDisk':
../../src/libxl/xen_xl.c:779:17: error: enumeration value 'LIBXL_DISK_BACKEND_STANDALONE'
not handled in switch [-Werror=switch-enum]
switch (libxldisk->backend) {
^~~~~~
cc1: all warnings being treated as errors
The interesting fact is that switch already has a default branch (which ought
to cover such new addition), but the error is triggered as -Wswitch-enum
gives a warning about an omitted enumeration code even if there is a default
label.
Also there is a similar issue in libxlUpdateDiskDef() which I have reproduced
after fixing the first one, but it that case the corresponding switch doesn't
have a default branch.
Fix both issues by inserting required enumeration item to make the compiler
happy and adding ifdef guard to be able to build against old Xen libraries
as well (without LIBXL_HAVE_DEVICE_DISK_SPECIFICATION). Also add a default
branch to switch in libxlUpdateDiskDef().
Please note, that current patch doesn't implement the proper handling of
LIBXL_DISK_BACKEND_STANDALONE and friends, it is just intended to fix
the regression immediately to unblock the osstest. Also it worth mentioning
that current patch won't solve the possible additions in the future.
