We do so in the vast majority of places, so there's no problem of adding
the attribute to enforce it by the complier and fix a few leftover
places.
This was originally pointed out by Coverity as a recent change triggered
it's warning that our code checked the vast majority of returns from
virStrToLong_ui.
There's no need to use it since we have this shiny functions
that even checks for conversion and overflow errors.

In the future we might need to track state of individual images. Move
the readonly and shared flags to the virStorageSource struct so that we
can keep them in a per-image basis.
Replace:
if (virBufferError(&buf)) {
virBufferFreeAndReset(&buf);
virReportOOMError();
...
}
with:
if (virBufferCheckError(&buf) < 0)
...
This should not be a functional change (unless some callers
misused the virBuffer APIs - a different error would be reported
then)
Commit ac63014c introduced a regression in the conversion of Xen
xm config to XML by emitting an empty <cmdline>. Prior to this
commit, <cmdline> was omitted if the xm config was missing (or
contained an empty) 'extra='.
In addition to extra= xm supported a root= option which was supposed
to be incorporated into the final command line. Handle that for "virsh
domxml-from-native xen-xm". Tested with the libxl backend.

A future patch wants to create disk definitions with non-zero
default contents; to avoid crashes, all callers that allocate
a disk definition should go through a common point.
I found allocation points by looking for any code that increments
ndisks, as well as any matches for ALLOC.*disk. Most places that
modified ndisks were covered by the parse from XML to domain/device
definition by initial domain creation or device hotplug; I also
hand-checked all drivers that generate a device struct on the
fly during getXMLDesc.

Currently we were storing domain feature flags in a bit field as the
they were either enabled or disabled. New features such as paravirtual
spinlocks however can be tri-state as the default option may depend on
hypervisor version.
To allow storing tri-state feature state in the same place instead of
having to declare dedicated variables for each feature this patch
refactors the bit field to an array.
If an OOM occurs in xenFormatXM when formatting to the

The xenParseXM sets def->nconsoles to 1 before claling
VIR_REALLOC_N on def->consoles. So if the alloc fails
due to OOM, the cleanup code will crash accessing a
console that does not exist.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
There will soon be other items related to pci hostdevs that need to be
in the same part of the hostdevsubsys union as the pci address (which
is currently a single member called "pci". This patch replaces the
single member named pci with a struct named pci that contains a single
member named "addr".
Format the address using the helper instead of having similar code in
multiple places.
This patch also fixes leak of the MAC address string in
ebtablesRemoveForwardAllowIn() and ebtablesAddForwardAllowIn() in
src/util/virebtables.c

We have historically allowed 'aio' as a synonym for 'raw' for
back-compat to xen, but since a future patch will move to using
an enum value, we have to pick one to be our preferred output
name. This is a slight change in the output XML, but the sexpr
and xm outputs should still be identical, and the input XML can
still use either form.

Parsing xen-xm format configuration will fail if UUID is not
specified, e.g.
virsh domxml-from-native xen-xm some-config-without-uuid
error: internal error parsing xm config failed
Initially I thought to skip parsing the UUID in xenParseXM() when
not present in the configuration, but this results in a UUID of
all zeros since it is never set
virsh domxml-from-native xen-xm /tmp/jim/bug-773621_pierre-test
<domain type='xen'>
<name>test</name>
<uuid>00000000-0000-0000-0000-000000000000</uuid>
...
which certainly can't be correct since this is the UUID the xen
tools use for dom0.
This patch takes the approach of generating a UUID when it is not
specified in the configuration.
Any time we have a string with no % passed through gettext, a
translator can inject a % to cause a stack overread. When there
is nothing to format, it's easier to ask for a string that cannot
be used as a formatter, by using a trivial "%s" format instead.
In the past, we have used --disable-nls to catch some of the
offenders, but that doesn't get run very often, and many more
uses have crept in. Syntax check to the rescue!
The syntax check can catch uses such as
virReportError(code,
_("split "
"string"));
by using a sed script to fold context lines into one pattern
space before checking for a string without %.
This patch is just mechanical insertion of %s; there are probably
several messages touched by this patch where we would be better
off giving the user more information than a fixed string.
