* 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.

nsc_gpio.c
|
|
|
|
National Semiconductor GPIO common access methods.
|
|
|
|
struct nsc_gpio_ops abstracts the low-level access
|
|
operations for the GPIO units on 2 NSC chip families; the GEODE
|
|
integrated CPU, and the PC-8736[03456] integrated PC-peripheral
|
|
chips.
|
|
|
|
The GPIO units on these chips have the same pin architecture, but
|
|
the access methods differ. Thus, scx200_gpio and pc8736x_gpio
|
|
implement their own versions of these routines; and use the common
|
|
file-operations routines implemented in nsc_gpio module.

NB: this work was tested on the Geode SC-1100 and PC-87366 chips.
|
|
NSC sold the GEODE line to AMD, and the PC-8736x line to Winbond.
