Since /usr/local is where ports live, it's reasonable to assume
that a grep binary found in there will have been installed via
ports and will thus be GNU grep.

macOS is similar to FreeBSD in that it ships non-GNU versions
of several utilities that we need in the base system.
macOS actually includes GNU make already, but unfortunately due
to licensing reasons the tool is permanently stuck in 2006, so
even in that case users are better off installing a recent
version from Homebrew along with the dozens of other libvirt
dependencies that already need to be obtained that way.
Note that, unlike FreeBSD ports, Homebrew is fully consistent
in adding the 'g' prefix to the name of the GNU tools, so we
can detect GNU grep without additional hacks.

As explained in the comment in build-aux/Makefile.in, the
version of sed included in the FreeBSD base system is not GNU
sed, which our syntax-check rules expect; as a result, many
checks will fail with
gmake: gsed: No such file or directory
/bin/sh: gsed: not found
Similarly to what we're already doing with GNU make and GNU
grep, look for GNU sed during the configuration step and fail
early if it's not available.

Previously, we accepted empty bridge name, because some old versions of
VMWare Workstation did not put it into the config. But this doesn't make
much sense - to have an interface type bridge with no name. We
circumvented this problem by generating an empty name but that is
equally wrong.
Therefore, fill in missing bridge names (according to the documentation
[1] the default bridge name is VMnet0) and error out if bridge name is
missing.

When testing locally built daemons on a systemd host there can be quite
a few systemd units that need temporarily stopping, and ideally
restarting after the test is complete. This becomes a massive burden
when modular daemons are running and you want to test libvirtd, as a
huge number of units need stopping.
The run script can facilitate this usage by looking at what units are
running and automatically stopping any that are known to conflict with
the daemon that is about to be run. This is only done when running as
root, since non-root libvirtd does not (currently) use systemd.

Recently, a few commits back I've switched bunch of code to
g_steal_pointer() using coccinelle. Problem was that the semantic
patch used was slightly off:
@@
expression a, b;
@@
+ b = g_steal_pointer(&a);
- b = a;
... when != a
- a = NULL;
Problem is that, "... when != a" is supposed to jump over those
lines, which don't contain expression a. My idea was to replace
the following pattern too:
ptrX = ptrY;
if (something(ptrZ) < 0) goto error;
ptrY = NULL;
But what I missed is that the following pattern is also matched
and replaced:
ptrX = ptrY;
if (something(ptrX) < 0) goto error;
ptrY = NULL;
This is not necessarily correct - as demonstrated by our hotplug
code. The real problem is ambiguous memory ownership transfer
(functions which add device to domain def take ownership only on
success), but to not tackle the real issue let's revert those
parts.

The order in which virNetworkUpdate() accepts @section and
@command arguments is not the same as in which it passes them
onto networkUpdate() callback. Until recently, it did not really
matter, because calling the API on client side meant arguments
were encoded in reversed order (compared to the public API), but
then on the server it was fixed again - because the server
decoded RPC (still swapped), called public API (still swapped)
and in turn called the network driver callback (with reversing
the order - so magically fixing the order).
Long story short, if the public API is called even number of
times those swaps cancel each other out. The problem is when the
API is called an odd numbed of times - which happens with split
daemons and the right URI. There's one call in the client (e.g.
virsh net-update), the other in a hypervisor daemon (say
virtqemud) which ends up calling the API in the virnetworkd.
The fix is obvious - fix the order in which arguments are passed
to the callback.
But, to maintain compatibility with older, yet unfixed, daemons
new connection feature is introduced. The feature is detected
just before calling the callback and allows client to pass
arguments in correct order (talking to fixed daemon) or in
reversed order (talking to older daemon).
Unfortunately, older client talking to newer daemon can't be
fixed. Let's hope that it's less frequent scenario.

The ESX implementation of virConnectListAllDomains() follows
pretty much implementations in other drivers: it has local array
of virDomainPtr-s which (if requested by caller) is filled by
actual domains or not (if the caller is interested only in the
count of domains).
Anyway, in case of the former, the passed @domains argument is
set to the local array, which is then set to NULL to prevent it
from freeing under cleanup label. Pretty standard pattern.
Except, the local array is set to NULL always. Even if the local
array is not stolen. Fortunately, this doesn't lead to a memory
leak, because if caller is not interested in the array, none is
allocated. But it doesn't set good example and also breaks my
spatch rules.

Some SRIOV PFs don't have a netdev associated with them (the spec
apparently doesn't require it). In most cases when libvirt is dealing
with an SRIOV VF, that VF must have a PF, and the PF *must* have an
associated netdev (the only way to set the MAC address of a VF is by
sending a netlink message to the netdev of that VF's PF). But there
are times when we don't need for the PF to have a netdev; in
particular, when we're just getting the Switchdev Features for a VF,
we don't need the PF netdev - the netdev of the VF (apparently) works
just as well.
Commit 6452e2f5 (libvirt 5.1.0) *kind of* made libvirt work around PFs
with no netdevs in this case - if virNetDevGetPhysicalFunction
returned an error when setting up to retrieve Switchdev feature info,
it would ignore the error, and then check if the PF netdev name was
NULL and, if so it would reset the error object and continue on rather
than returning early with a failure. The problem is that by the time
this special handling occured, the error message about missing netdev
had already been logged, which was harmless to proper operation, but
confused the user.
Fortunately there are only 2 users of virNetDevGetPhysicalFunction, so
it is easy to redefine it's API to state that a missing netdev name is
*not* an error - in that case it will still return success, but the
caller must be prepared for the PF netdev name to be NULL. After
making this change, we can modify the two callers to behave properly
with the new semantics (for one of the callers it *is* still an error,
so the error message is moved there, but for the other it is okay to
continue), and our spurious error messages are a thing of the past.
