I've been playing with the latest snapshot of cfenvd, and noticed this:
in cfenvd.c, in function RejectAnomaly:
srand((unsigned int)time(NULL));
if (drand48() < 0.7) /* 70% chance of using full value - as in learning
policy */
{
return new;
}
else
{
return average+2.0*dev;
}
drand48() is always returning 0, because it wants to be initalized
with srand48(), not srand().
