When libvirt first implemented a stable and configurable MAC address
for the bridges created for libvirt virtual networks (commit
5754dbd56d, in libvirt v0.8.8) most distro stable releases didn't
support explicitly setting the MAC address of a bridge; the bridge
just always assumed the lowest numbered MAC of all attached
interfaces. Because of this, we stabilized the bridge MAC address by
creating a "dummy" tap interface with a MAC address guaranteed to be
lower than any of the guest tap devices' MACs (which all started with
0xFE, so it's not difficult to do) and attached it to the bridge -
this was the inception of the "virbr0-nic" device that has confused so
many people over the years.
Even though the linux kernel had recently gained support for
explicitly setting a bridge MAC, we deemed it unnecessary to set the
MAC that way, because the other (indirect) method worked everywhere.
But recently there have been reports that the bridge MAC address was
not following the setting in the network config, and mismatched the
MAC of the dummy tap device (which was still correct). It turns out
that this is due to a change in systemd-242 that persists whatever MAC
address is set for a bridge when it's initially started. According to
the systemd NEWS file entry for version 242
(https://github.com/systemd/systemd/blob/master/NEWS):
"if a bridge interface is created without any slaves, and gains
a slave later, then now the bridge does not inherit slave's MAC."
This change was the result of:
https://github.com/systemd/systemd/issues/3374
(apparently if there is no MAC saved for a bridge by the name of a
bridge being created, the random MAC generated during creation is
saved, and then that same MAC is used to explicitly set the MAC each
time it is created). Once a bridge has an explicitly set MAC, the "use
the lowest numbered MAC of attached devices" rule is ignored, so our
dummy tap device is like the goggles - it does nothing! (well, almost).
We could whine about changes in default behavior, etc. etc., but
because the change was in response to actual user problems, that seems
likely a fruitless task. Fortunately, time has marched on, and even
distro releases that are old enough that they are no longer supported
by upstream libvirt (e.g. RHEL6) have support for explicitly setting a
bridge device MAC address, either during creation or with a separate
ioctl after creation, so we can now do that.
To enable explicitly setting the mac during bridge creation, we add a
mac arg to virNetDevBridgeCreate(). In the case of platforms where
the bridge is created with a netlink RTM_NEWLINK message, we just add
that mac to the message. For platforms that still use an ioctl (either
SIOCBRADDBR or SIOCIFCREATE2), we make a separate call to
virNetDevSetMAC() after creating the bridge.
(NB: I was unable to test the calling of virNetDevSetMAC() from the
SIOCIFCREATE2 (BSD) version of virNetDevBridgeCreate(); even though I
managed to get a FreeBSD system setup and libvirt built there, when I
tried to start the default network the SIOCIFCREATE2 ioctl itself
failed, so it never even got to the virNetDevSetMAC(). That leaves the
FreeBSD implementation untested.)
This makes the dummy tap pointless for purposes of setting the MAC
address, but it is still useful for IPv6 DAD initialization (which
apparently requires at least one interface to be attached to the
bridge and online), as well as for setting an initial MTU for the
bridge, so it hasn't been removed.
(NB: we can safely *always* call virNetDevBridgeCreate() with
&def->mac from the network driver because, in spite of the existence
of a "mac_specified" bool in the config suggesting that it may not
always be present, in reality a mac address will always be added to
any network that doesn't have one - this is guaranteed in all cases by
commit a47ae7c004)

Although until now, any use of the extra_args argument (a pointer to a
struct containing extra attributes to add the the RTM_NEWLINK message)
would always have the ifindex and mac set, so the code could assume it
was safe to add both to the message if extra_args != NULL. There is
now a use for setting a MAC address in the RTM_NEWLINK without setting
the ifindex, so we should check each of these separately.

Commit 01ca4010d8 (libvirt v5.1.0) moved address reservation for
hotplugged interface devices up to an earlier point in
qemuDomainAttachNetDevice(), because that function calls
qemuDomainSupportsNicdev() (in the case of
VIR_DOMAIN_NET_TYPE_VHOSTUSER), and qemuDomainSupportsNicdev() needs
to know the address type (for ARM machinetypes) and returns incorrect
results when the address type is "none".
This bugfix unfortunately caused a regression, because it also made PCI
address reservation happen before we noticed that the device was a
*hostdev* interface. Those interfaces are hotplugged by just calling
out to qemuDomainAttachHostdevDevice() - that function would then also
attempt to reserve the *same PCI address* that had just been reserved
in qemuDomainAttachNetDevice().
The solution is to move the bit of code that short-circuits out to
virDomainHostdevAttach() up *even earlier* so that no PCI address has
been allocated by the time it's called.

According to rfc3986:
2.3. Unreserved Characters
Characters that are allowed in a URI but do not have a reserved
purpose are called unreserved. These include uppercase and lowercase
letters, decimal digits, hyphen, period, underscore, and tilde.
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
URIs that differ in the replacement of an unreserved character with
its corresponding percent-encoded US-ASCII octet are equivalent: they
identify the same resource. However, URI comparison implementations
do not always perform normalization prior to comparison (see Section
6). For consistency, percent-encoded octets in the ranges of ALPHA
(%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D), period (%2E),
underscore (%5F), or tilde (%7E) should not be created by URI
producers and, when found in a URI, should be decoded to their
corresponding unreserved characters by URI normalizers.
Thus we must not include few other characters which don't match
c_isalpha to conform to the rules.

If we are updating the current checkpoint when redefining by mentioning
the current checkpoint as a parent of the newly redefined one we don't
have to clear it first.

There's no point in clearing the current checkpoint when we are just
changing the definition of the current checkpoint as by the virtue of the
'update_current' flag the same checkpoint would become current in
qemuCheckpointCreateXML.

The 'other' variable was used to store the parent of the redefined
checkpoint and then the existing version of the currently redefined
checkpoint. Make it less confusing by adding a 'parent' variable for the
first case.

Libtool gets a wrong order of arguments of libraries to install and it
fails when installing libvirt-admin.so that libvirt.so is not yet
installed. Caused by commit <3097282d8668693eb4b7c3fb1b4fe5b474996b9c>.

In few places we have the following code pattern:
int ret;
... /* @ret is not accessed here */
ret = f(...);
return ret;
This pattern can be written less verbose:
...
return f(...);
This patch was generated with following coccinelle spatch:
@@
type T;
constant C;
expression f;
identifier ret;
@@
-T ret = C;
... when != ret
-ret = f;
-return ret;
+return f;
Afterwards I needed to fix a few places, e.g. comment in
virDomainNetIPParseXML() was removed too because coccinelle
thinks it refers to @ret while in fact it doesn't. Also in few
places it replaced @ret declaration with a few spaces instead of
removing the line. But nothing terribly wrong.

These two functions have pattern that's preventing us from
simpler virAsprintf() -> g_strdup_printf() transition. Modify
their logic a bit.

In a few places our code relies on the fact that virAsprintf()
not only prints to allocated string but also that it returns the
length of that string. Fortunately, only few such places were
identified:
https://www.redhat.com/archives/libvir-list/2019-September/msg01382.html
In case of virNWFilterSnoopLeaseFileWrite() and virFilePrintf()
we can use strlen() right after virAsprintf() to calculate the
length. In case of virDoubleToStr() it's only caller checks for
error case only, so we can limit the set of returned values to
just [-1, 0].

There is no need to have the libvirt-admin.so library definition in the
src directory. In addition the library uses directly code from admin
sub-directory so move the remaining bits there as well.
