[libvirt] [PATCH 00/26] Resolve more Coverity issues

[John Ferlan]

Sorry for the large dump, but before I got too involved in other things
I figured I'd go through the list of the remaining 68 Coverity issues
from the new version in order to reduce the pile. Many are benign, some
seemingly false positives, and I think most are error paths. The one
non error path that does stick out is the qemu_driver.c changes in the
qemuDomainSetBlkioParameters() routine where 'param' and 'params' were
used differently between LIVE and CONFIG. In particular, in CONFIG the
use of 'params->field' instead of 'param->field'.

One that does bear looking at more closely and if someone has a better
idea is avoiding a false positive resource_leak in remote_driver.c. I
left a healthy comment in the code - you'll know when you see it.

These patches get the numbers down to 19 issues.  Of the remaining
issues - some are related to Coverity thinking that 'mgetgroups' could
return a negative value with an allocated groups structure (which I'm
still scratching my head over).  There is also a few calls to
virJSONValueObjectGetNumberUlong() in qemu_monitor_json.c that don't
check status, but I'm not sure why - just didn't have the research
cycles for that.
