dynamic memory automatically zero'd

[Stefan Schulze Frielinghaus]

Hi all,

if you allocate memory, e.g. via malloc(3), then it is automatically set
to zero. This is actually a security feature quite common nowadays. I
would like to know when this feature has made it into Fedora or in RHEL.
Is this a mandatory feature of some security policy as e.g. the Common
Criteria? I couldn't find much information about this. Therefore, any
pointers, hints and so on are welcomed!

Regards,
Stefan
