In certain rare occasions qemu can transition a block job which was
already 'ready' into 'standby' and then back. If this happens in the
following order libvirt will get confused about the actual job state:
1) the block copy job is 'ready' (job->state == QEMU_BLOCKJOB_STATE_READY)
2) user calls qemuDomainBlockJobAbort with VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT
flag but without VIR_DOMAIN_BLOCK_JOB_ABORT_ASYNC
3) the block job is switched to synchronous event handling
4) the block job blips to 'standby' and back to 'ready', the event is
not processed since the blockjob is in sync mode for now
5) qemuDomainBlockJobPivot is called:
5.1) 'job-complete' QMP command is issued
5.2) job->state is set to QEMU_BLOCKJOB_STATE_PIVOTING
6) code for synchronous-wait for the job completion in qemuDomainBlockJobAbort
is invoked
7) the waiting loop calls qemuBlockJobUpdate:
7.1) job->newstate is QEMU_BLOCKJOB_STATE_READY due to 4)
7.2) qemuBlockJobEventProcess is called
7.3) the handler for QEMU_BLOCKJOB_STATE_READY overwrites
job->state from QEMU_BLOCKJOB_STATE_PIVOTING to QEMU_BLOCKJOB_STATE_READY
8) qemuDomainBlockJobAbort is looking for a finished job, so waits again
9) qemu finishes the blockjob and transitions it into 'concluded' state
10) qemuBlockJobUpdate is triggered again, this time finalizing the job.
10.1) job->newstate is = QEMU_BLOCKJOB_STATE_CONCLUDED
job->state is = QEMU_BLOCKJOB_STATE_READY
10.2) qemuBlockJobEventProcessConcluded is called, the function
checks whether there was an error with the blockjob. Since
there was no error job->newstate becomes
QEMU_BLOCKJOB_STATE_COMPLETED.
10.3) qemuBlockJobEventProcessConcludedTransition selects the action
for the appropriate block job type where we have:
case QEMU_BLOCKJOB_TYPE_COPY:
if (job->state == QEMU_BLOCKJOB_STATE_PIVOTING && success)
qemuBlockJobProcessEventConcludedCopyPivot(driver, vm, job, asyncJob);
else
qemuBlockJobProcessEventConcludedCopyAbort(driver, vm, job, asyncJob);
break;
Since job->state is QEMU_BLOCKJOB_STATE_READY,
qemuBlockJobProcessEventConcludedCopyAbort is called.
This patch forbids transitions to QEMU_BLOCKJOB_STATE_READY if the
previous job state isn't QEMU_BLOCKJOB_STATE_RUNNING or
QEMU_BLOCKJOB_STATE_NEW.

The new enum helpers use a set of flags to modify their behaviour, but
the declared set of flags is semantically confusing:
typedef enum {
VIR_XML_PROP_OPTIONAL = 0, /* Attribute may be absent */
VIR_XML_PROP_REQUIRED = 1 << 0, /* Attribute may not be absent */
Since VIR_XML_PROP_OPTIONAL is declared as 0 any other flag shadows it
and makes it impossible to detect. The functions are not able to detect
a semantic nonsense of VIR_XML_PROP_OPTIONAL | VIR_XML_PROP_REQUIRED and
it's a perfectly valid statement for the compilers.
In general having two flags to do the same boolean don't make sense and
the implementation doesn't fix any shortcomings either.
To prevent mistakes, rename VIR_XML_PROP_OPTIONAL to VIR_XML_PROP_NONE,
so that there's always an enum value used with the calls but it doesn't
imply that the flag makes the property optional when the actual value is
0.
