* 0day explit mitigation * Memory corruption prevention * Privilege escalation prevention * Buffer over flow prevention * File System corruption defense * Thread escape prevention This may very well be the most intensive inclusion to BrooklynR. This will not be part of an x86 suite nor it will be released as tool kit. The security core toolkit will remain part of kernel base.

* DLCI/FRAD Definitions for Frame Relay Access Devices. DLCI devices are
|
|
* created for each DLCI associated with a FRAD. The FRAD driver
|
|
* is not truly a network device, but the lower level device
|
|
* handler. This allows other FRAD manufacturers to use the DLCI
|
|
* code, including its RFC1490 encapsulation alongside the current
|
|
* implementation for the Sangoma cards.
|
