Found by Coverity. Because there's an "if ((cur = strstr(base, "revision"))
!= NULL) {" followed by a "base = cur" coverity notes that 'base' could
then be NULL causing the return to the top of the "while ((tmp_base =
strstr(base, "processor")) != NULL) {" to have strstr deref a NULL 'base'
pointer because the setting of base at the bottom of the loop is unconditional.
Alter the code to set "base = cur" after processing each key. That will
"ensure" that base doesn't get set to NULL if both "cpu" and "revision"
do no follow a "processor".
While a /proc/cpuinfo file that has a "processor" key but with neither
a "cpu" nor a "revision" doesn't seem feasible, the code is written as if
it could happen, so we have to account for it.

Calls to virFileReadAll after a VIR_ALLOC that return NULL all show
a memory leak since 'ret' isn't virSysinfoDefFree'd and normal path
"return ret" doesn't free outbuf.

Whole implementations along with helper totalling screens of code were
conditionally compiled. That made the code totally unreadable and
untestable. Rename functions to have the architecture in the name so
that all can be compiled at the same time and introduce header to allow
testing them all.
Proposed formal coding conventions encourage defining typedefs for
vir[Blah] and vir[Blah]Ptr separately from the associated struct named
_vir[Blah]:
typedef struct _virBlah virBlah;
typedef virBlah *virBlahPtr;
struct _virBlah {
...
};
At some point in the past, I had submitted several patches using a
more compact style that I prefer, and they were accepted:
typedef struct _virBlah {
...
} virBlah, *virBlahPtr;
Since these are by far a minority among all struct definitions, this
patch changes all those definitions to reflect the style prefered by
the proposal so that there is 100% consistency.
After the system has been booted, it should not change.
Cache the return value of virSystemdHasMachined.
Allow starting and terminating machines with just one
DBus call, instead of three, reducing the chance of
the call timing out.
Also introduce a small function for resetting the cache
to be used in tests.
Both virSystemdTerminateMachine and virSystemdCreateMachine
propagate the error to tell between a non-systemd system
and a hard error.
In virSystemdGetMachineNameByPID both are treated the same,
but an error is ignored by the callers.
Split out the checks into a separate function.
Make common helpers testNetworkObjFindByUUID and testStoragePoolObjFindByUUID
which will replace the repeated patter for each to find objects by UUID.
As a bonus, the error message processing will also provide the failed uuidstr
rather than a generic error message.
Rather than have multiple places using the same pattern to find
a network by name using virNetworkObjFindByName, create a common
helper which will provide a consistent error message as well.
Rather than have continued repeated sequences of :
testDriverLock()
xxx = vir*ObjFindByName()
testDriverUnlock()
if (xxx == NULL) {
virReportError
goto cleanup;
}
Make some common helpers which will use the pattern and make a single
reference using a single common error message.
Altered for Interfaces, Storage Pools, Storage Volumes, and Node Devices.
For each the common error message can now also indicate which 'name' was
not found. For Storage Volumes, the "new" error will be more specific
rather than just invalid argument.
In an effort to be consistent with the source module, alter the function
prototypes to follow the similar style of source with the "type" on one
line followed by the function name and arguments on subsequent lines with
with argument getting it's own line.

Now that we have some qemuSecurity wrappers over
virSecurityManager APIs, lets make sure everybody sticks with
them. We have them for a reason and calling virSecurityManager
API directly instead of wrapper may lead into accidentally
labelling a file on the host instead of namespace.

All existing Haswell CPUID data were gathered from CPUs with broken TSX.
Let's add new data for Haswell with correct TSX implementation.

All Intel Haswell processors (except Xeon E7 v3 with stepping >= 4) have
TSX disabled by microcode update. As not all CPUs are guaranteed to be
patched with microcode updates we need to explicitly disable TSX on
affected CPUs to avoid its accidental usage.

The original test didn't use family/model numbers to make better
decisions about the CPU model and thus mis-detected the model in the two
cases which are modified in this commit. The detected CPU models now
match those obtained from raw CPUID data.

Instantiating "host" CPU and querying it using qom-get has been the only
way of probing host CPU via QEMU until 2.9.0 implemented
query-cpu-model-expansion for x86_64. Even though libvirt never really
used the old way its result can be easily converted into the one
produced by query-cpu-model-expansion. Thus we can reuse the original
test data and possible get new data from hosts where QEMU does not
support the new QMP command.
