Back in commit 2c71d3826, which appeared in libvirt-1.2.3 in April
2014, the location used to store saved MAC addresses and vlan tags of
SRIOV VFs was changed from /var/run/libvirt/qemu to
/var/run/libvirt/hostdevmgr. For backward compatibility the code was
made to continue looking in the old location for the files when it
didn't find them in the new location.
It's now been 6 years, and even if there was somebody still running
libvirt-1.2.3 on their system, that system would now be out of support
for libvirt, so there would be no way for them to upgrade to a new
libvirt that no longer looks in "oldStateDir" for the files. So
let's no longer look in "oldStateDir" for the files!

virGetConnectNetwork() calls
virGetConnectGeneric(), which calls
virConnecCacheInitialize(), which is actually a call (only once) to
virConnectCacheOnceInit() which calls
virThreadLocalInit() several times, which calls
pthread_key_create()
If pthread_key_create() fails, it (of course) doesn't log an error
(because it's not a part of libvirt), nor does any other function on
the call chain all the way up to virGetConnectNetwork(). But none of
the callers of virGetConnectNetwork() log an error either, so it is
possible that an API could fail due to virGetConnectNetwork() failing,
but would only log "an error was encountered, but the cause is
unknown. Deal with it." (paraphrasing).
(In all likelyhood, virConnectCacheOnceInit() is going to be called at
some earlier time, and almost certainly pthread_key_create() will
never fail (and if it does, the user will have *much* bigger problems
than an obtuse error message from libvirt)).

posix_fallocate() might be not supported by a filesystem, for example,
it's not supported by ZFS. In that case it fails with
return code 22 (EINVAL), and thus safezero_posix_fallocate() returns -1.
As safezero_posix_fallocate() is the first function tried by safezero()
and it tries other functions only when it returns -2, it fails
immediately without falling back to other methods, such as
safezero_slow().
Fix that by returning -2 if posix_fallocate() returns EINVAL, to give
safezero() a chance to try other functions.

The current virPCIDeviceNew() signature, receiving 4 uints in sequence
(domain, bus, slot, function), is not neat.
We already have a way to represent a PCI address in virPCIDeviceAddress
that is used in the code. Aside from the test files, most of
virPCIDeviceNew() callers have access to a virPCIDeviceAddress reference,
but then we need to retrieve the 4 required uints (addr.domain, addr.bus,
addr.slot, addr.function) to satisfy virPCIDeviceNew(). The result is
that we have extra verbosity/boilerplate to retrieve an information that
is already available in virPCIDeviceAddress.
A better way is presented by virNVMEDeviceNew(), where the caller just
supplies a virPCIDeviceAddress pointer and the function handles the
details internally.
This patch changes virPCIDeviceNew() to receive a virPCIDeviceAddress
pointer instead of 4 uints.

If QEMU driver fails to initialize for whatever reason (it can be
as trivial as a typo on qemu.conf), the control jumps to error
label in qemuStateInitialize() where qemuStateCleanup() is called
which frees the driver. But the daemon then asks drivers to
prepare for shutdown, which in case of QEMU driver is implemented
in qemuStateShutdownPrepare(). In here, the driver is
dereferenced but since it was freed earlier, the pointer is NULL
which leads to instant crash.
Solution is simple - just check if qemu_driver is not NULL. But
doing so only in qemuStateShutdownPrepare() would push the
problem down to virStateShutdownWait(), well
qemuStateShutdownWait(). Therefore, duplicate the trick there

As explained in QEMU commit 4c257911dcc7c4189768e9651755c849ce9db4e8
intel-pt features should never be included in the CPU models as it was
not supported by KVM back then and even once it started to be supported,
users have to enable it by passing pt_mode=1 parameter to kvm_intel
module. The Icelake-* CPU models with intel-pt included were added to
QEMU 3.1.0 and removed right in the following 4.0.0 release (and even in
3.1.1 maintenance release).
In libvirt 6.10.0 I introduced 'removed' attribute for features included
in our CPU model definitions which we can use to drop intel-pt from
Icelake-* CPU models. Back then I explained we can safely do so only for
features which could never be enabled, which is not the case of intel-pt.
Theoretically, it could be possible to create an environment in which
QEMU would enable intel-pt without asking for it explicitly: it would
need to use a new enough kernel (not available at the time of QEMU
3.1.0) and pt_mode KVM parameter in combination with QEMU 3.1.0 running
a domain with q35 machine type and all that on a CPU which didn't really
exist at that time.
Migrating such domain to a host with newer SW stack including libvirt
with this patch applied would result in incompatible guest ABI (the
virtual CPU would lose intel-pt). However, QEMU changed its CPU models
unconditionally and thus migration would not work even without this
patch. That said, it is safe to follow QEMU and remove the feature from
Icelake-* CPU models in our cpu_map.

virPCIGetNetName is used to get the name of the netdev associated with
a particular PCI device. This is used when we have a VF name, but need
the PF name in order to send a netlink command (e.g. in order to
get/set the MAC address of the VF).
In simple cases there is a single netdev associated with any PCI
device, so it is easy to figure out the PF netdev for a VF - just look
for the PCI device that has the VF listed in its "virtfns" directory;
the only name in the "net" subdirectory of that PCI device's sysfs
directory is the PF netdev that is upstream of the VF in question.
In some cases there can be more than one netdev in a PCI device's net
directory though. In the past, the only case of this was for SR-IOV
NICs that could have multiple PF's per PCI device. In this case, all
PF netdevs associated with a PCI address would be listed in the "net"
subdirectory of the PCI device's directory in sysfs. At the same time,
all VF netdevs and all PF netdevs have a phys_port_id in their sysfs,
so the way to learn the correct PF netdev for a particular VF netdev
is to search through the list of devices in the net subdirectory of
the PF's PCI device, looking for the one netdev with a "phys_port_id"
matching that of the VF netdev.
But starting in kernel 5.8, the NVIDIA Mellanox driver began linking
the VFs' representor netdevs to the PF PCI address [1], and so the VF
representor netdevs would also show up in the net
subdirectory. However, all of the devices that do so also only have a
single PF netdev for any given PCI address.
This means that the net directory of the PCI device can still hold
multiple net devices, but only one of them will be the PF netdev (the
others are VF representors):
$ ls '/sys/bus/pci/devices/0000:82:00.0/net'
ens1f0 eth0 eth1
In this case the way to find the PF device is to look at the
"phys_port_name" attribute of each netdev in sysfs. All PF devices
have a phys_port_name matching a particular regex
(p[0-9]+$)|(p[0-9]+s[0-9]+$)
Since there can only be one PF in the entire list of devices, once we
match that regex, we've found the PF netdev.

guest writes might not be guaranteed while with virtio-pmem it
is.
To express this new model at domain XML level, I've chosen the
following:
<memory model='virtio-pmem' access='shared'>
<source>
<path>/tmp/virtio_pmem</path>

In the past, the MTU of libvirt virtual network bridge devices was
implicitly set by setting the MTU of the "dummy tap device" (which was
being added in order to force a particular MAC address from the
bridge). But the dummy tap device was removed in commit ee6c936fbb
(libvirt-6.8.0), and so the mtu setting in the network is ignored.
The solution is, of course, to explicitly set the bridge device MTU
when it is created.
Note that any guest interface with a larger MTU that is attached will
cause the bridge to (temporarily) assume the larger MTU, but it will
revert to the bridge's own MTU when that device is deleted (this is
not due to anything libvirt does; it's just how Linux host bridges
work).

This patch only sets the MTU if managed='no' is *not* set (so, if it
is 'yes', or just not set at all).
Note that MTU of the tap is also set when connecting the tap to a

So far we assumed that any vhostuser interface is plugged into an
OVS bridge and thus 'ovs-vsctl' exists. But this is not always
true. In testing scenarios it is possible to create a vhostuser
interface with this tool dpdk-testpmd (part of dpdk RPM) which
creates/connects to UNIX socket needed for vhostuser. Of course,
since there is no OVS then there is no interface name in which
case virNetDevOpenvswitchGetVhostuserIfname() should return 0.
The rest of APIs that assume OVS are not 'fixed' because we still
want them to fail (e.g. getting statistics, plugging interface
into an OVS bridge, unplugging it from an OVS bridge, ...).
The only API that is fixed is
virNetDevOpenvswitchGetVhostuserIfname() because it is called
explicitly when starting a guest (and callers are okay if no name
was found).
The other way to fix this bug seems to be to simply require
'ovs-vsctl' on spec file level, but that is too heavy gun given
that vhostuser is used by a small set of our users (assumption
made on requirements for vhostuser). Also, this way would drag in
yet another dependency for all users (even those who want minimal
libvirt).

Now that this function can be called regardless of interface type (and
whether or not we have a conn for the network driver), let's actually
call it for all interface types. This will assure that we re-connect
any disconnected bridge devices for <interface type='bridge'> as
mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=1730084#c26

The bridge reattach functionality in this function should be called
for interface types other than just type='network', so make it
callable for any type - it just becomes a NOP for types where no
action is needed.
In the case of <interface type='network'> we need to create a port in
the network driver, and for both type='network and type='bridge' we
need to reattach the bridge device (note that
virDomainNetGetActualBridgeName() gets the bridge name from the
appropriate (and different!) location for either type of interface).
All other interfaces currently require no action.
modifying callers of this function to actually call it for all
interface types is in the next patch. For now the behavior should be
identical pre and post-patch.
(NB: the conn argument can now legitimately be NULL, so we need to
change the ATTRIBUTE_NONNULL() directive for the function's
declaration - I noticed when making this change that argument 3 (the
NetDefPtr) could never be NULL, so I added ATTRIBUTE_NONNULL(3) while
removing ATTRIBUTE_NONNULL(1) (conn)).

dnsmasq usually prints out a version string like this:
Dnsmasq version 2.82 [...]
but a user reported that the build of dnsmasq included with pihole has
a version string like this:
Dnsmasq version pi-hole-2.81 [...]
We parse the dnsmasq version number to figure out if the dnsmasq
binary supports certain features. Since we expect the version number
(and it must be only numbers!) to start on the first non-space after
the string "Dnsmasq version", we fail to parse this format of the
version string.
Rather than spending a bunch of time trying to get pihole to change
that, we can just make our parsing more permissive - after searching
for "Dnsmasq version", we'll skip ahead to the first decimal digit,
rather than just the first non-space.
(NB: The features we're checking for purely by looking at version
number have been in all releases of dnsmasq since at least 2012, so we
could actually just remove the reading of the version number
completely. However it's possible (although *highly* unlikely)
that some new feature would be added to dnsmasq in the future and we
would need to add that code back.)

The lookup didn't do anything apart from comparing the sysfs paths
anyway since that's what makes each mdev unique.
The most ridiculous usage of the old logic was in
virHostdevReAttachMediatedDevices where in order to drop an mdev
hostdev from the list of active devices we first had to create a new
mdev and use it in the lookup call. Why couldn't we have used the
hostdev directly? Because the hostdev and mdev structures are
incompatible.
The way mdevs are currently removed is via a write to a specific sysfs
attribute. If you do it while the machine which has the mdev assigned
is running, the write call may block (with a new enough kernel, with
older kernels it would return a write error!) until the device
is no longer in use which is when the QEMU process exits.
The interesting part here comes afterwards when we're cleaning up and
call virHostdevReAttachMediatedDevices. The domain doesn't exist
anymore, so the list of active hostdevs needs to be updated and the
respective hostdevs removed from the list, but remember we had to
create an mdev object in the memory in order to find it in the list
first which will fail because the write to sysfs had already removed
the mdev instance from the host system.
And so the next time you try to start the same domain you'll get:
"Requested operation is not valid: mediated device <path> is in use by
driver QEMU, domain <name>"

The two scenarios were found by Coverity after a seemingly-unrelated
change to virLXCProcessSetupInterfaceTap() (in commit ecfc2d5f43), and
explained by John Ferlan here:
https://www.redhat.com/archives/libvir-list/2020-December/msg00810.html
To re-explain:
a) On entry to virLXCProcessSetupInterfaceTap() if net->ifname != NULL
then a copy of net->ifname is made into parentVeth, and a reference
to *that* pointer is sent down to virNetDevVethCreate().
b) If parentVeth (aka net->ifname) is a template name (e.g. "blah%d"),
then virNetDevVethCreate() calls virNetDevGenerateName(), and if
virNetDevGenerateName() successfully generates a usable name
(e.g. "blah27") then it will free the original template string
(which is pointed to by net->ifname and by parentVeth), then
replace the pointer in parentVeth with a pointer to the new
string. Note that net->ifname still points to the now-freed
template string.
c) returning back up to virLXCProcessSetupInterfaceTap(), we check if
net->ifname == NULL - it *isn't* (still contains stale pointer to
template string), so we don't replace it with the pointer to the new
string that is in parentVeth.
d) Result: the new string is leaked once we return from
virLXCProcessSetupInterfaceTap(), while there is a dangling pointer
to the old string in net->ifname.
There is also a leak if there is a failure somewhere between steps (b)
and (c) above - the failure cleanup in virNetDevVethCreate() will only
free the newly-generated parentVeth string if the original pointer was
NULL (narrator: "It wasn't."). But it's a new string allocated by
virNetDevGenerateName(), not the original string from net->ifname, so
it really does need to be freed.
The solution is to make a copy of the entire original string into a
g_autofree pointer, then iff everything is successful we g_free() the
original net->ifname and replace it by stealing the string returned by
virNetDevVethCreate().

In all cases *except* when parsing status XML as libvirt is being

name (aka "<target dev='blah'/>" aka net->ifname) that could have been
generated by virNetDevGenerateName(). This means that during the setup
when a domain is being started (e.g. during
virLXCProcessSetupInterfaceTap()) it is pointless to call
virNetDevReserveName() with any setting of net->ifname that has come
from the XML parser - it is guaranteed to not fit the pattern of any
auto-generated name, and so the call is just a NOP anyway.
