Demonstrate how VIR_RETURN_PTR is used by refactoring qemu_block.c
Signed-off-by: Peter Krempa <pkrempa@redhat.com>
Reviewed-by: Ján Tomko <jtomko@redhat.com>
With the introduction of more and more internal data types which support
VIR_AUTOPTR it's becoming common to see the following pattern:
VIR_AUTOPTR(virSomething) some = NULL
virSomethingPtr ret = NULL;
... (ret is not touched ) ...
VIR_STEAL_PTR(ret, some);
return ret;
This patch introduces a macro named VIR_RETURN_PTR which returns the
pointer directly without the need for an explicitly defined return
variable and use of VIR_STEAL_PTR. Internally obviously a temporary
pointer is created to allow setting the original pointer to NULL so that
the VIR_AUTOPTR function does not free the memory which we want to
actually return.
The name of the temporary variable is deliberately long and complex to
minimize the possibility of collision.

Commit 5b9819eedc started using the virFileWrapper APIs in
the test program, and correctly called them only in the section
of code guarded by WITH_QEMU; however, a single call to the
virFileWrapperClearPrefixes() function ended up in the
hypervisor-agnostic section, causing a build failure on MinGW.
Move the call to the QEMU-only section; while at it, also drop
the virFileWrapperRemovePrefix() calls, which are entirely
redundant since we'd drop all prefixes immediately afterwards
anyway.

If a management application wants to use firmware auto selection
feature it can't currently know if the libvirtd it's talking to
support is or not. Moreover, it doesn't know which values that
are accepted for the @firmware attribute of <os/> when parsing
will allow successful start of the domain later, i.e. if the mgmt
application wants to use 'bios' whether there exists a FW
descriptor in the system that describes bios.
This commit then adds 'firmware' enum to <os/> element in
<domainCapabilities/> XML like this:
<enum name='firmware'>
<value>bios</value>
<value>efi</value>
</enum>
We can see both 'bios' and 'efi' listed which means that there
are descriptors for both found in the system (matched with the
machine type and architecture reported in the domain capabilities
earlier and not shown here).

Commit b647d2195 introduced a use-after-free situation when the caller
is trying to delete a snapshot and its children: if the callback
function deletes the parent, it is no longer safe to query the parent
to learn which children also need to be deleted (where we previously
saved deleting the parent for last). To fix the problem, while still
maintaining support for topological visits of callback functions, we
have to stash off any information needed for later traversal prior to
using a callback function (virDomainMomentForEachChild already does
this, it is only virDomainMomentActOnDescendant that was running into
problems).
Sadly, the testsuite did not cover the problem at the time. Worse,
even though I later added commit 280a2b41e to catch problems like
this, and even though that test is indeed sufficient to detect the
problem when run under valgrind or suitable MALLOC_PERTURB_ settings,
I'm guilty of not running the test in such an environment. Thus,
v5.2.0 has a regression that could have been prevented had we used the
testsuite to its full power. On the bright side, deleting snapshots
requires ACL domain:snapshot, which is arguably as powerful as
domain:write, so I don't think this use-after-free forms a security
hole.
At some point, it would be nice to convert virDomainMomentObj into a
virObject, at which point, the solution is even simpler: add
virObjectRef/Unref around the callback. But as that will require
auditing even more places in the code, I went with the simplest patch
for the regression fix.

was only read when libvirtd started and cached for the daemon's
lifetime. However, the CPU microcode can change anytime (updating the
microcode package can automatically upload it to the CPU) and we need to
stop caching it to avoid using stale CPU model data.
