Hum, it is a bit complex as the allocated dst is saved in
the definition a few lines earlier:
/* Labelling normally operates on src, but we need
* to actally label the dst here, so hack the config */
def->src = dst;
and then in cleanup it's overriden again with the value saved at the
start of the function:
cleanup:
def->src = tmpsrc;
virDomainAuditDisk(vm, NULL, def->src, "attach", ret == 0);
the leak is real and that free certainly need to be added but maybe
there is a bit of cleanup needed rather than just adding the VIR_FREE()
I will let someone with more knowledge of that code part decide :-)
